Description
Si:AT SLrDE DEVICE
BAC:KGROUND OF THE INVENTION
The present invention relates ganerally to automotive vehicle seating and, more particularly, to a seat slide device of the type used in manually operated seat adjustment ",echallis",s.
Virtually all modern motor vehicies are equipped with seating systems that can be selectively ad~usted for providing l"creased oomfort and convenlence to the seat occupants. In many manually actuated systems, the seat is supported for movement on a seat adjustment ",echanisr" that can be selectively ~rtu~'~d for permitting the seat occupant to adJust the ho,i~onl~l (I.e., "fore" and "aft") position of the seat. Typically, the seat adjustment ",ecl,anl~", Includes a pair of laterally spaced seat slide devices each having a lower track flxed to the vehicle's fioor structure, an upper track fixed to the seat and which is supported for sliding movement on the lower track, and a manually operable latching n~eclianis. " for (~ Iy latching the upper track (and seat) in the desired adjusted po~ition relative to the lower track. In addition, a cor",non handle or linkage ass~r"~ly is also generally provided for causing sy"cl,fonous actuation of each of the latching ",echani_rns aCsoc; ~lec! with the laterally spaced seat slide devicss to Inhibit lateral (i.~., side-to-side) misallgnment of the seat.
Co"""on'J, the latching ",ecllani~",s illCCIr~ JldleCi into conventional seat slide devices include a lock plate atlached to the stdlional~r lower track and a latch plate supported from the upper track for pivotable movement between a "locked" posnion of enyage" ,enl with the lock plate and a 'I~ d' position of d;sangagemerit II,ei~ h. Typically, a plurality of locking prs;e '~ns (i.e., teeth, hooks, tabs, etc.) are formed on one of tha latch plate and the lock plate for interdigitated engage" ,enl with a series of locking apertures formed on the other of the plates in rt,sponse to movement of the latch pl~a to the "iocked" position. The _1_ 210976~
manually operable handle assen,bly permits the seat occupant to pivot the latch plate to the Itleased"positionwhenitisdesiredtoadJustthehG~i~Gl~tdlpositiono7theseat. Inaddition, the latcliing r"echar~i~ "s are spring-biased for normally urging the latch plata toward the "locked" position.
In an effort to inhibit sep~, ~llon (~.e., Upeeling'') of the upper track from the lower track during collisions and other heavily loaded conditions it is known to structurally ~interlock" the upper track on the lower track. Such an a"dngel"enl is di:~tlosed in U.S. Pat.
No. 4,957 267 to Terai wherein the Inwardly turned vertical fianges formed on the oppos;~e lateral edges of the upper track are nested within longitudinal cha~ ,e:s formed by outwardly turned vertical flanges on the lower track. To p~rmR sliding movement and minimize lateral "play", a plurality of balls are roldtably di~"osed above the longltudinal channels and betwezn a horl~o"lal surface portion of the upper track and a hori~o"l~l portion of the ouh~ardiy turned 1ianges on the lower track. A similar i"lerlochi,lg track a,.anger"enl is shown in U.S.
Pat No. 4,487,459 to Rees with the excepliQn that plastic slides are s~ Ihs~i~uted for the balls.
However, while most conventional seat slide dsvices work s~ c~ ry for their i,ltanded purpose, they are typically complex in design and construction and e~,enshre to manufacture.
SUMMARY OF THE INVENTION
Accordingly, it is an obJect of the present invention to provide an improved seat sllde device that Is rel~liv.,ly simple in design and construction, i"e,~,er,s;ve to ~dbricale and ass~" '-16, and yet is durable and highly reliablQ.
A more detailed obJect of the present Invention is 10 provide a seat slide device with an l"terlochi"gly interfitted track a"~,~ge",ent havlng high load-bearing capabilities for Inhibiting "peeling" of th0 upper tracks under highly loaded conditions. Fetainer asse,n~l"e s are ope,t,bly disposed between the i"lei lock;, Iyiy i, Itel ~tled tracks for causing smooth sliding movement, inhiblting lateral (i.e., "side-to-slde") play and l,dnsfer,i"~ vertically directed (i.e., 210~760 "peel") loads from the seat and upper tracks into the lower track and the vehicle's t_;n~orced sill and/or floor structure.
A further object of ~he present invention is to provide a seat slide device with an Improved latching ",ecl,an.~", for pe""~ ,g the seat occupant to manually adjust the longitudinal position of the seat. More speciflcally, the latching ",ecl,anis", includes a latch plate supported from the upper track for s~ 3~ rectilin0ar mov0ment alon~ a vertical plana between positions of "locked" engag6r"ellt and ~ d" d:_engagel"6nt relative to a lock plate fixed to the lower track. Moreover, the latch plate Includes a plurality of locking pl~ e ~ ns that are adapted to move into and out of interdigitated engagel"enl with a series of locking apertures formed in the lock plate. The locking prc,e 'icns have a segmsn~ed tooU ,fo" " that includes camming means for facilitating CGr"~ inlel dls-' " n ~G " ~v3"g initial engage",e,l~ of the locking pr~;2 ';~a5 within ~he locking apertures. The seg",anted tooth form includes a first locking portion for facilitating initial receipt within the locking apertures, a second locking portion for causing co", lil-. interdigitated anyage",ent and a camming portion for providing a ramped tr~nsition between the first and second locking portions Thus, the flrst locking portion deflnes an "anti-ratchet" engage",~nl position and the second locking portions defines an "anti-chucking" enyag~r"enl position.
According to yet another obJect of the present invention, the improved latching ",ecl\an: ." can be ins~alled on the seat slide dsvice as a sul-asser"bly to further reduce system cost and cGr";l~
From the ~ 119 speciflcation taken In conjunction with the acc~r"pa"ylng dri~w3~lys and appended claims, other obJects, features, and advantages of the present invention will become appare,)l to those skilled In the art.

DETAILED DESCRIPTION OF THE PFitl-tHi~tU EMBODIMENT
According to the dl~l.lgs, and pal'ic~'- ly Figures 1 and 2, an e,~",pla,y manual seat adlustment ,..echanl_." 101s shown. In general, manual seat adjustment "echani_." 10 is of the type co",l"only referred to as a ' two-way" adjuster that is adapted to permlt a seat occupant to sE'e l-ely adjust the longitudinal (i.e., "fore" and "afl") position of a seat. To provide means for such longitudinal adjustment, seat adjustment ",e-:l,anl_." 10 Includes a palr o~ laterally spaced seat slide devices 12 which each include a lower track 14 and an upper track 16. A pair of manually oper ~'e latchlng ",echani~."s 18 are also :
210~76~
provided and which are operably coupled by handle means 20 for permitting sy-,cl"ùnous actuation thereof. Thus, se e ivo actuation of latching ."echan;~.ns 18 permit upper tracks 16 to slide longi ~ lly with respect to lower tracks 14.
Lower tracks 14 are elongd1ed structural ."e.nbe,~ that are secured via suitable ~c,~1ener~ 22 to mounting brachet~ 24 which, in turn are secured to the vehicl~ s r~l"folc~d slll and/or floor structure. As best seen from Figure 3 and 4, lower tracks 14 are each conflgured to Include a central U-shaped portion having a planar base seg,.,e"l 26 and a palr ~f !aterally-spaced vertical legs or side walls 28 extending 11 ,e(~ 5~ Ul 11. Formed at the distal end of zach side wall 28 is an outwardly bent lip or flange 30 which defines an elangaled slide channel 32. Pre~er~bly, each flange 30 Includes an outwardly e len ing hori or,lal sey")enl 34, a dû.~ a dl~ extendiny vertlcal segr,.el)t 36, and an Inwardly angulated end seg",en13~.
As noted, aach upper track 16 is slidably mounted on its respective lower track 14 for relativ0 movement In the fore and aft directions. Seat mounting ~aslene,~i, such as lI"eaded studs 40 and nuts 42, are secur~d to upper tracks 16 and are adapted to be secured to a ~el.~fùrced seat pan section of the seat. In this manner, the s0at is mounted for sliding movement with upper tracks 16 on lower tracks 14.
With partlcular r~ere,lce to Figures 2 through 4 upper tracks 16 are shown as P ~nga1ad structural l"ember~; havlng a generally rectangular shape in cross-sectlon with a central channel 44 formed along its bottom edge for enabllng the U-shaped portion of lower tracks 14 to be slidably posllioned therein. More speciticaliy each upper track 16 has a planar upper ho,l ontal sey"~enl 46 which overlies the entire lateral width of lower track 14, and vertical slde walls 48 which extend do.~..;;a~dly from opplcF'I~ lateral edges of hG,i on1al seg",enl 46. Inwardly bent lips or flanges 50 are formed at the lower end of slde walls 48 snd each Includes a planar inwardly extending hGli O ltdl say,nant 51 an upwardly extending vertical segment 52 and an ou~, dll angulated end sey"~enl 54. As best seen from Figure 4, central channel 44 is defined between the laterally spaced vertical segments 52 while a portion of each vertical segment 52 and angulated end seyn,el ,154 is slidably disposed withinone of slide channEls 32 of lowertrack 14. Mor00ver, upper seg",erlt 40 vertical side walls 48 and inwardly bent flanges 50 define a second se~ of Glongaled slide channels 66 within which outwardly bent nanges 30 of lower track 14 ar0 slidably retained. Thus upper track 16 is Vh l~erlochi, Iyly" Il~ on lower track 14 in a manner which facilitates the lransfer of vertically directed (i.e., ~peei") loads to the vehici0's ,~ ;.,iorced sill and/or floor structure.
Moreover the i"lerlochi"g'y i, llenllled track a" ~ngeme"~ of the present invention is designed to Rfold-in" on itself upon exertion of heavy "peel" loading thereon to augment ~es;slance to sepa,dlion of upper tracks 16 from lower tracks 14.
A pair of retainer asser"~"~ s 58 are interposed between each set of interfitted upper tracks 16 and lower tracks 14 for enabling smooth sliding movement o~ upper tracks 16 on lower tracks 14 along a sul,slar, inl'y hori~onlal plane. i~etainer ass~r, '-"es 5~ are shown to include a unitary retainer body 60 having a central ,~cessed portion 62 and a pair of raised planar ho,kGnlal surfaces 64 ad3acent to ~ecessed portion 62 which, in turn, are each joined to a down-turned portion 66. When installed between the i"le, fitled tracks, raised planar surfaces 64 are interposed betwsen upper ho,i~on~al seg",~"l 46 of upper track 18 and hori,ontdl sagmel,ts 34 of outv...rdly bent flanges 30 on lower tracks 14. Fl"ll,er",Gre, the distal ends of down-turned portions 66 are inwardly rolled-over to form generally cylindrical lips 68 each having a pair of longitudinally-spaced openings 70 formed therein within which ball bea,inys 72 are rolalably retained. More spe 'ic ~Iy, ball bea,in~s 72 are entrapped within cylindrlcal lips 68 for rolling movement in the longitudinal guld~ .~ a~s formed between an outer surface of angulated end seg",~"ts 38 of lower tracks 14 and the arcuate surface formed at the internal ll ,ler:,el l;on of side walls 48 and lower hol i~or)lal segments ~1 of upper tracks 16. Thus, ball bea,i,,ys 72 are a"anged in rolling engager"el)l with each of the IllterlGcked tracks to minimize dc"eLt;en the,~bst~een while l,~ns~"i"g the upwardly directed vertical (i.e., "peel") loads ~rom upper tracks 16 to lower tracks 14 and, in turn, to the 21~97~0 ~ehicle's re;.,~orced sill and/or floor structure. In addition, a cylindrical roller 74 is retained within a central cut~ut portion 76 of retainer body 60 so as to provide smooth sliding movement while l,ans~r,iny d~ ~ dly directed vertical loads ~rom upper tracks 16 into lower tracks 14.
As noted, each of th~ manually ope, ~le latching ",echar,is.na 18 can be s~,lchronously Pctl~ted lor permitting fore and aft sliding movement of upper tracks 16 (and the seat) on lower tracks 14. In general, each latching ~"echa~ ." 18 is a spring-blased a"di1gel"er,l that can be readily associated with a seat slide device. More particularly, latch m6cha~ n,s 18 are constructed to include a latching co",ponerlt that moves rec.~ilinearly along a vertical plane for overcoming pf~t'e "s collllllonly ACSoc;~?d with conventional swlng-type latching systems. As wlll be ullderslood, left and rlght latching ",echan.3;"s 18 are Identical or mirror-image equivalents that ar~ co" ,pa~:t in construction and which can be pre-ass6r"~'ed as a s~b~Qse",bll for easy i" ~ai' n into slide devices 12.
As shown, each latch ",ecl ,an;_." 18 includes a latch plate 80 that is operably coupled to a linkage member 82 of handle 20 such that upward movement of handle 20 causes latch plates 80 to move llnearly along a vertical plane from the "locked" posltion of Figure 6 to the "1~'3. ~ed" position shown in Figure 7. In the 'I.~leased' position, a series of locking prc'e~lcns or teeth 84 formed on latch plate 80 are d;_Engaged from a series of locklng apertures 86 that are formed along an inner longitudinal edge surface of a lock plate 88 that is flxed to, or integral with, support member 24. A spring member, such as leaf spring 90, Is adàpted to bias latch plate 80, linkage 82 and handle 20 in a do/,. ,..~ d direction such that locking teeth 84 are normally biased toward the "locked" position (Figure 6) f~r facilitating Interdigltated engayem6l ,t with locking apertures 86. As wlll be appr~s': ' - d, when locking teeth 84 are inserted into locking apertures 86, subsec;uent longitudinal movement of upper tracks 16 is inhibiting, whereby the seat is lul~ l~ ' Iy locked in a desired hori~o" 'Iy ad;llst position.
21~97~
Accor." ,g to the particular e~),bod, nenl shown, latch plate 80 is rztained for sul sla,~ '1y rectilinear movement along a vertical plane be~Neen first and second brackets 100 and 102, respectively. First bracket 100 is a right-angled member having 3 hGI;~Gllldl surface 104 that is adapted to be secured to an external surface of upper track 16, and a vertical surface 106 that projects inwardly to su~slal~ir'l~ enclose locking plate 88. First bracket 100 further includes a series of three slongaled slots 108 formed in vertical surface 106. Second bracket 102 is laterally spaced from flrst bracket 100 and is secured thereto by suitable ~a~tenar~, such as rivets 110. In addition, second bracket 102 also includes a series of three elongaled slots 112 which are alignable with elongated slots 108 of flrst bracket 100.
Llnkage member 82 is pivotably coupled about pivot 114 to a r eal ~_rd embossed portion 115 on vertical sutfaca 106 of first bracket 100 and includes a slot 116 that is alignable with the central ones of aligned sets of slots 108 and 112.
Latch plate 80 Is disposed between first and second brackets 100 and 102, respectively, and includes a pair of transverse pins 118 that are fixed to latch plate 80 so as to extend through the outside ones of slots 108 and 112 formed in flrst bracket 100 and second bracket 102, respectively. In addition, latch plate 80 also includes an elongaled central post 120 that is po~itioned beh~een transverse pins 118 and which extends through the central ones of the aligned sets of slots 108 and t 12 in flrst and second brackets 100 and 102, fespect;vel,/, as well as slot 116 In linkage 82. Pins 118 and post 120 have a similar wldth dimension and are adapted to be guided for smooth rectilinear movement within the above-noted slots in a manner Inhibiting rotation of latch plate 80. Thus, latch plate 80 moves along a vertlcal rec~"lnea, path in response 1O pivotable movement of handle 20 and linkage 82 about pivot 114. Since slot 116 in linkage 82 is shorter and wider than th0 aligned series of bracket slots 108 and 1.12, central post 118 er,gages a lower end surfaces of slot 116 in tesponse to upward pivotal movement of linkage 82 fot moving latch plate 80 to the '~eleased' position of Figure 7. Ukewise, release of handle 20 causes do~.,.J? d pivotal movement of linkage 82 about pivot 114 such that an upper end surface of link slot 116 acts on central post 118 for forcibly urging latch plate 80 toward the "locked" posltlon.
To provide a fail-safe latching a"ange",enl, leaf spring 90 is retained above latch plate 80to augment the inertial do.~ ,.vai!ci locking action of pr~ L'iCn 84within locklng apertures 86. In addition, the free ends 122 of leaf spring 90 are slidably d;~ posed In cut-out tabs formed in first bracket 100 such that its central cambered portion 124 Is adapted to directly act on latch plats 80 such that central post 120 Is urged into engayei"ent with the lower end surface of link slot 116 In the "locked" posRlon. To permit Installation of latch ",echal1;s." 18 as a SUIJ~SSeIIIbIY~ tha forward end of linkage 82 can be quickly coupled to the free ends of handle 20 i~ . ,g mounting of hori~u, ,ldl surface 104 on first bracket 100 to an upper planar surface of upper tracks 16. Moreover, since latch plate 80 is enclosed wlthin first bracket 100, the upward linsar travel of latch plate 80 is limited below the level of upper track 16 to facilitate utilization of latching ",ecl,ar,;~.."s 18 with various cushion pans and seating arrangements.
With particular reference now to Figure 8, a seg",ented toothfor", for locking teeth 84iS i;~losed which is considered to be an improvement over conventional linear or Involute tooth forms. In general locking teeth 84 are ~."r"~t,lcal about their respective centerlines and Include a genen 'Iy 'Idr"ped" edga contourtor defining a dual-position locking a~dnge",er,l. More particularly, the seylllellled lo~ltll~ fûr locking teeth 84 includes a flrst locking portion 126 for facilitating initial receipt within locking apertures 86t a second locking portlon 128 for causlng cGn, ' :~. Interdigitated engage",e,lt, and a cammln3 portion 130 providing a ramped ha,)s;llon between flrst and second locking portions 126 and 128, respectively. Thus, the 10cked" posltion for latching ",echal,:3."s 18 Is actually divide Into nrst and second engage",e"l p c 'i~ ns. In the flrst engager"er)l position, first locking portion 126is inltialiy i"la, .!ig~ d with locking apertures 86 for deflning an "anti-, d~chellr,gr positlon.
Thereanar, slight movement by the seat occupant causes locking teeth ~4 to be guided by g 2~ 0~760 ~ts ramped l,~nsition of camming portion 130 into the second engagel"enl position. Due to cor"-'o: interdigi~ated engagement in the second posHion, chucking movement of ths seat is inh'b't~l thereby defining an "anti-chucking" position. While the center tooth of locking teeth 84 is shown to be slightly lon~er than the outer teeth, this is consldered a design cholce for thc particular embodiment shown.
First locking portion 126 of seg",6nted teeth 84 is defined by the gensn 'Iy rectangular tip portion thereof and includes linear edge surfaces 132. Plt:ielvbly, linear edge surfaces 132 are substantially parallel to the centerline of teeth ~4. Moreover, the length of linear edge surfaces 132 is selected to e,nended inwardly from the terminal enq ot each tooth 84 to a first l,~ns;lion point. More pr~fe.~bly, the wldth of first locklng portion 126 is selected to ba smaller (I.e., appro,~;", Ely 50%-75%) than the width of locking apertures 86 for tacilitating the flrst or "anti-ratchet" engagemen~ position (see phanlc r" line posltion of Figure 8). Iuler",ediale cammlng portion 130 Ir,'~rconnec1s first locking portion 126 to second locklng portion 128 and Includes a ramped llanv'ti~n surfaces 134 for guiding one set of locklng aperture edge surfaces 136 from Initial enydger"enl with respectivo ones of linear edge surfaces 132 (I.e., the Ranti-ratchet" position) into co".

As shown in Figure 8, camming surfaces 130 extend between the first l,ansition point and a second t,~n ' ~n point located at the outer extent of edge surfaces 138. While camming surfaces 130 are shown to be arcuate, a wlll be appreclaled that other profiles (i.e., linear) are conler"F' ' ç ! which would likewise provide a sultable camming surface.
According to the l~r~r, ed embodiment, edge surfaces 138 of second locking portion 128 are linear and slightly tapered relative to the centerline of teeth 84.

BAC:KGROUND OF THE INVENTION
The present invention relates ganerally to automotive vehicle seating and, more particularly, to a seat slide device of the type used in manually operated seat adjustment ",echallis",s.
Virtually all modern motor vehicies are equipped with seating systems that can be selectively ad~usted for providing l"creased oomfort and convenlence to the seat occupants. In many manually actuated systems, the seat is supported for movement on a seat adjustment ",echanisr" that can be selectively ~rtu~'~d for permitting the seat occupant to adJust the ho,i~onl~l (I.e., "fore" and "aft") position of the seat. Typically, the seat adjustment ",ecl,anl~", Includes a pair of laterally spaced seat slide devices each having a lower track flxed to the vehicle's fioor structure, an upper track fixed to the seat and which is supported for sliding movement on the lower track, and a manually operable latching n~eclianis. " for (~ Iy latching the upper track (and seat) in the desired adjusted po~ition relative to the lower track. In addition, a cor",non handle or linkage ass~r"~ly is also generally provided for causing sy"cl,fonous actuation of each of the latching ",echani_rns aCsoc; ~lec! with the laterally spaced seat slide devicss to Inhibit lateral (i.~., side-to-side) misallgnment of the seat.
Co"""on'J, the latching ",ecllani~",s illCCIr~ JldleCi into conventional seat slide devices include a lock plate atlached to the stdlional~r lower track and a latch plate supported from the upper track for pivotable movement between a "locked" posnion of enyage" ,enl with the lock plate and a 'I~ d' position of d;sangagemerit II,ei~ h. Typically, a plurality of locking prs;e '~ns (i.e., teeth, hooks, tabs, etc.) are formed on one of tha latch plate and the lock plate for interdigitated engage" ,enl with a series of locking apertures formed on the other of the plates in rt,sponse to movement of the latch pl~a to the "iocked" position. The _1_ 210976~
manually operable handle assen,bly permits the seat occupant to pivot the latch plate to the Itleased"positionwhenitisdesiredtoadJustthehG~i~Gl~tdlpositiono7theseat. Inaddition, the latcliing r"echar~i~ "s are spring-biased for normally urging the latch plata toward the "locked" position.
In an effort to inhibit sep~, ~llon (~.e., Upeeling'') of the upper track from the lower track during collisions and other heavily loaded conditions it is known to structurally ~interlock" the upper track on the lower track. Such an a"dngel"enl is di:~tlosed in U.S. Pat.
No. 4,957 267 to Terai wherein the Inwardly turned vertical fianges formed on the oppos;~e lateral edges of the upper track are nested within longitudinal cha~ ,e:s formed by outwardly turned vertical flanges on the lower track. To p~rmR sliding movement and minimize lateral "play", a plurality of balls are roldtably di~"osed above the longltudinal channels and betwezn a horl~o"lal surface portion of the upper track and a hori~o"l~l portion of the ouh~ardiy turned 1ianges on the lower track. A similar i"lerlochi,lg track a,.anger"enl is shown in U.S.
Pat No. 4,487,459 to Rees with the excepliQn that plastic slides are s~ Ihs~i~uted for the balls.
However, while most conventional seat slide dsvices work s~ c~ ry for their i,ltanded purpose, they are typically complex in design and construction and e~,enshre to manufacture.
SUMMARY OF THE INVENTION
Accordingly, it is an obJect of the present invention to provide an improved seat sllde device that Is rel~liv.,ly simple in design and construction, i"e,~,er,s;ve to ~dbricale and ass~" '-16, and yet is durable and highly reliablQ.
A more detailed obJect of the present Invention is 10 provide a seat slide device with an l"terlochi"gly interfitted track a"~,~ge",ent havlng high load-bearing capabilities for Inhibiting "peeling" of th0 upper tracks under highly loaded conditions. Fetainer asse,n~l"e s are ope,t,bly disposed between the i"lei lock;, Iyiy i, Itel ~tled tracks for causing smooth sliding movement, inhiblting lateral (i.e., "side-to-slde") play and l,dnsfer,i"~ vertically directed (i.e., 210~760 "peel") loads from the seat and upper tracks into the lower track and the vehicle's t_;n~orced sill and/or floor structure.
A further object of ~he present invention is to provide a seat slide device with an Improved latching ",ecl,an.~", for pe""~ ,g the seat occupant to manually adjust the longitudinal position of the seat. More speciflcally, the latching ",ecl,anis", includes a latch plate supported from the upper track for s~ 3~ rectilin0ar mov0ment alon~ a vertical plana between positions of "locked" engag6r"ellt and ~ d" d:_engagel"6nt relative to a lock plate fixed to the lower track. Moreover, the latch plate Includes a plurality of locking pl~ e ~ ns that are adapted to move into and out of interdigitated engagel"enl with a series of locking apertures formed in the lock plate. The locking prc,e 'icns have a segmsn~ed tooU ,fo" " that includes camming means for facilitating CGr"~ inlel dls-' " n ~G " ~v3"g initial engage",e,l~ of the locking pr~;2 ';~a5 within ~he locking apertures. The seg",anted tooth form includes a first locking portion for facilitating initial receipt within the locking apertures, a second locking portion for causing co", lil-. interdigitated anyage",ent and a camming portion for providing a ramped tr~nsition between the first and second locking portions Thus, the flrst locking portion deflnes an "anti-ratchet" engage",~nl position and the second locking portions defines an "anti-chucking" enyag~r"enl position.
According to yet another obJect of the present invention, the improved latching ",ecl\an: ." can be ins~alled on the seat slide dsvice as a sul-asser"bly to further reduce system cost and cGr";l~
From the ~ 119 speciflcation taken In conjunction with the acc~r"pa"ylng dri~w3~lys and appended claims, other obJects, features, and advantages of the present invention will become appare,)l to those skilled In the art.

DETAILED DESCRIPTION OF THE PFitl-tHi~tU EMBODIMENT
According to the dl~l.lgs, and pal'ic~'- ly Figures 1 and 2, an e,~",pla,y manual seat adlustment ,..echanl_." 101s shown. In general, manual seat adjustment "echani_." 10 is of the type co",l"only referred to as a ' two-way" adjuster that is adapted to permlt a seat occupant to sE'e l-ely adjust the longitudinal (i.e., "fore" and "afl") position of a seat. To provide means for such longitudinal adjustment, seat adjustment ",e-:l,anl_." 10 Includes a palr o~ laterally spaced seat slide devices 12 which each include a lower track 14 and an upper track 16. A pair of manually oper ~'e latchlng ",echani~."s 18 are also :
210~76~
provided and which are operably coupled by handle means 20 for permitting sy-,cl"ùnous actuation thereof. Thus, se e ivo actuation of latching ."echan;~.ns 18 permit upper tracks 16 to slide longi ~ lly with respect to lower tracks 14.
Lower tracks 14 are elongd1ed structural ."e.nbe,~ that are secured via suitable ~c,~1ener~ 22 to mounting brachet~ 24 which, in turn are secured to the vehicl~ s r~l"folc~d slll and/or floor structure. As best seen from Figure 3 and 4, lower tracks 14 are each conflgured to Include a central U-shaped portion having a planar base seg,.,e"l 26 and a palr ~f !aterally-spaced vertical legs or side walls 28 extending 11 ,e(~ 5~ Ul 11. Formed at the distal end of zach side wall 28 is an outwardly bent lip or flange 30 which defines an elangaled slide channel 32. Pre~er~bly, each flange 30 Includes an outwardly e len ing hori or,lal sey")enl 34, a dû.~ a dl~ extendiny vertlcal segr,.el)t 36, and an Inwardly angulated end seg",en13~.
As noted, aach upper track 16 is slidably mounted on its respective lower track 14 for relativ0 movement In the fore and aft directions. Seat mounting ~aslene,~i, such as lI"eaded studs 40 and nuts 42, are secur~d to upper tracks 16 and are adapted to be secured to a ~el.~fùrced seat pan section of the seat. In this manner, the s0at is mounted for sliding movement with upper tracks 16 on lower tracks 14.
With partlcular r~ere,lce to Figures 2 through 4 upper tracks 16 are shown as P ~nga1ad structural l"ember~; havlng a generally rectangular shape in cross-sectlon with a central channel 44 formed along its bottom edge for enabllng the U-shaped portion of lower tracks 14 to be slidably posllioned therein. More speciticaliy each upper track 16 has a planar upper ho,l ontal sey"~enl 46 which overlies the entire lateral width of lower track 14, and vertical slde walls 48 which extend do.~..;;a~dly from opplcF'I~ lateral edges of hG,i on1al seg",enl 46. Inwardly bent lips or flanges 50 are formed at the lower end of slde walls 48 snd each Includes a planar inwardly extending hGli O ltdl say,nant 51 an upwardly extending vertical segment 52 and an ou~, dll angulated end sey"~enl 54. As best seen from Figure 4, central channel 44 is defined between the laterally spaced vertical segments 52 while a portion of each vertical segment 52 and angulated end seyn,el ,154 is slidably disposed withinone of slide channEls 32 of lowertrack 14. Mor00ver, upper seg",erlt 40 vertical side walls 48 and inwardly bent flanges 50 define a second se~ of Glongaled slide channels 66 within which outwardly bent nanges 30 of lower track 14 ar0 slidably retained. Thus upper track 16 is Vh l~erlochi, Iyly" Il~ on lower track 14 in a manner which facilitates the lransfer of vertically directed (i.e., ~peei") loads to the vehici0's ,~ ;.,iorced sill and/or floor structure.
Moreover the i"lerlochi"g'y i, llenllled track a" ~ngeme"~ of the present invention is designed to Rfold-in" on itself upon exertion of heavy "peel" loading thereon to augment ~es;slance to sepa,dlion of upper tracks 16 from lower tracks 14.
A pair of retainer asser"~"~ s 58 are interposed between each set of interfitted upper tracks 16 and lower tracks 14 for enabling smooth sliding movement o~ upper tracks 16 on lower tracks 14 along a sul,slar, inl'y hori~onlal plane. i~etainer ass~r, '-"es 5~ are shown to include a unitary retainer body 60 having a central ,~cessed portion 62 and a pair of raised planar ho,kGnlal surfaces 64 ad3acent to ~ecessed portion 62 which, in turn, are each joined to a down-turned portion 66. When installed between the i"le, fitled tracks, raised planar surfaces 64 are interposed betwsen upper ho,i~on~al seg",~"l 46 of upper track 18 and hori,ontdl sagmel,ts 34 of outv...rdly bent flanges 30 on lower tracks 14. Fl"ll,er",Gre, the distal ends of down-turned portions 66 are inwardly rolled-over to form generally cylindrical lips 68 each having a pair of longitudinally-spaced openings 70 formed therein within which ball bea,inys 72 are rolalably retained. More spe 'ic ~Iy, ball bea,in~s 72 are entrapped within cylindrlcal lips 68 for rolling movement in the longitudinal guld~ .~ a~s formed between an outer surface of angulated end seg",~"ts 38 of lower tracks 14 and the arcuate surface formed at the internal ll ,ler:,el l;on of side walls 48 and lower hol i~or)lal segments ~1 of upper tracks 16. Thus, ball bea,i,,ys 72 are a"anged in rolling engager"el)l with each of the IllterlGcked tracks to minimize dc"eLt;en the,~bst~een while l,~ns~"i"g the upwardly directed vertical (i.e., "peel") loads ~rom upper tracks 16 to lower tracks 14 and, in turn, to the 21~97~0 ~ehicle's re;.,~orced sill and/or floor structure. In addition, a cylindrical roller 74 is retained within a central cut~ut portion 76 of retainer body 60 so as to provide smooth sliding movement while l,ans~r,iny d~ ~ dly directed vertical loads ~rom upper tracks 16 into lower tracks 14.
As noted, each of th~ manually ope, ~le latching ",echar,is.na 18 can be s~,lchronously Pctl~ted lor permitting fore and aft sliding movement of upper tracks 16 (and the seat) on lower tracks 14. In general, each latching ~"echa~ ." 18 is a spring-blased a"di1gel"er,l that can be readily associated with a seat slide device. More particularly, latch m6cha~ n,s 18 are constructed to include a latching co",ponerlt that moves rec.~ilinearly along a vertical plane for overcoming pf~t'e "s collllllonly ACSoc;~?d with conventional swlng-type latching systems. As wlll be ullderslood, left and rlght latching ",echan.3;"s 18 are Identical or mirror-image equivalents that ar~ co" ,pa~:t in construction and which can be pre-ass6r"~'ed as a s~b~Qse",bll for easy i" ~ai' n into slide devices 12.
As shown, each latch ",ecl ,an;_." 18 includes a latch plate 80 that is operably coupled to a linkage member 82 of handle 20 such that upward movement of handle 20 causes latch plates 80 to move llnearly along a vertical plane from the "locked" posltion of Figure 6 to the "1~'3. ~ed" position shown in Figure 7. In the 'I.~leased' position, a series of locking prc'e~lcns or teeth 84 formed on latch plate 80 are d;_Engaged from a series of locklng apertures 86 that are formed along an inner longitudinal edge surface of a lock plate 88 that is flxed to, or integral with, support member 24. A spring member, such as leaf spring 90, Is adàpted to bias latch plate 80, linkage 82 and handle 20 in a do/,. ,..~ d direction such that locking teeth 84 are normally biased toward the "locked" position (Figure 6) f~r facilitating Interdigltated engayem6l ,t with locking apertures 86. As wlll be appr~s': ' - d, when locking teeth 84 are inserted into locking apertures 86, subsec;uent longitudinal movement of upper tracks 16 is inhibiting, whereby the seat is lul~ l~ ' Iy locked in a desired hori~o" 'Iy ad;llst position.
21~97~
Accor." ,g to the particular e~),bod, nenl shown, latch plate 80 is rztained for sul sla,~ '1y rectilinear movement along a vertical plane be~Neen first and second brackets 100 and 102, respectively. First bracket 100 is a right-angled member having 3 hGI;~Gllldl surface 104 that is adapted to be secured to an external surface of upper track 16, and a vertical surface 106 that projects inwardly to su~slal~ir'l~ enclose locking plate 88. First bracket 100 further includes a series of three slongaled slots 108 formed in vertical surface 106. Second bracket 102 is laterally spaced from flrst bracket 100 and is secured thereto by suitable ~a~tenar~, such as rivets 110. In addition, second bracket 102 also includes a series of three elongaled slots 112 which are alignable with elongated slots 108 of flrst bracket 100.
Llnkage member 82 is pivotably coupled about pivot 114 to a r eal ~_rd embossed portion 115 on vertical sutfaca 106 of first bracket 100 and includes a slot 116 that is alignable with the central ones of aligned sets of slots 108 and 112.
Latch plate 80 Is disposed between first and second brackets 100 and 102, respectively, and includes a pair of transverse pins 118 that are fixed to latch plate 80 so as to extend through the outside ones of slots 108 and 112 formed in flrst bracket 100 and second bracket 102, respectively. In addition, latch plate 80 also includes an elongaled central post 120 that is po~itioned beh~een transverse pins 118 and which extends through the central ones of the aligned sets of slots 108 and t 12 in flrst and second brackets 100 and 102, fespect;vel,/, as well as slot 116 In linkage 82. Pins 118 and post 120 have a similar wldth dimension and are adapted to be guided for smooth rectilinear movement within the above-noted slots in a manner Inhibiting rotation of latch plate 80. Thus, latch plate 80 moves along a vertlcal rec~"lnea, path in response 1O pivotable movement of handle 20 and linkage 82 about pivot 114. Since slot 116 in linkage 82 is shorter and wider than th0 aligned series of bracket slots 108 and 1.12, central post 118 er,gages a lower end surfaces of slot 116 in tesponse to upward pivotal movement of linkage 82 fot moving latch plate 80 to the '~eleased' position of Figure 7. Ukewise, release of handle 20 causes do~.,.J? d pivotal movement of linkage 82 about pivot 114 such that an upper end surface of link slot 116 acts on central post 118 for forcibly urging latch plate 80 toward the "locked" posltlon.
To provide a fail-safe latching a"ange",enl, leaf spring 90 is retained above latch plate 80to augment the inertial do.~ ,.vai!ci locking action of pr~ L'iCn 84within locklng apertures 86. In addition, the free ends 122 of leaf spring 90 are slidably d;~ posed In cut-out tabs formed in first bracket 100 such that its central cambered portion 124 Is adapted to directly act on latch plats 80 such that central post 120 Is urged into engayei"ent with the lower end surface of link slot 116 In the "locked" posRlon. To permit Installation of latch ",echal1;s." 18 as a SUIJ~SSeIIIbIY~ tha forward end of linkage 82 can be quickly coupled to the free ends of handle 20 i~ . ,g mounting of hori~u, ,ldl surface 104 on first bracket 100 to an upper planar surface of upper tracks 16. Moreover, since latch plate 80 is enclosed wlthin first bracket 100, the upward linsar travel of latch plate 80 is limited below the level of upper track 16 to facilitate utilization of latching ",ecl,ar,;~.."s 18 with various cushion pans and seating arrangements.
With particular reference now to Figure 8, a seg",ented toothfor", for locking teeth 84iS i;~losed which is considered to be an improvement over conventional linear or Involute tooth forms. In general locking teeth 84 are ~."r"~t,lcal about their respective centerlines and Include a genen 'Iy 'Idr"ped" edga contourtor defining a dual-position locking a~dnge",er,l. More particularly, the seylllellled lo~ltll~ fûr locking teeth 84 includes a flrst locking portion 126 for facilitating initial receipt within locking apertures 86t a second locking portlon 128 for causlng cGn, ' :~. Interdigitated engage",e,lt, and a cammln3 portion 130 providing a ramped ha,)s;llon between flrst and second locking portions 126 and 128, respectively. Thus, the 10cked" posltion for latching ",echal,:3."s 18 Is actually divide Into nrst and second engage",e"l p c 'i~ ns. In the flrst engager"er)l position, first locking portion 126is inltialiy i"la, .!ig~ d with locking apertures 86 for deflning an "anti-, d~chellr,gr positlon.
Thereanar, slight movement by the seat occupant causes locking teeth ~4 to be guided by g 2~ 0~760 ~ts ramped l,~nsition of camming portion 130 into the second engagel"enl position. Due to cor"-'o: interdigi~ated engagement in the second posHion, chucking movement of ths seat is inh'b't~l thereby defining an "anti-chucking" position. While the center tooth of locking teeth 84 is shown to be slightly lon~er than the outer teeth, this is consldered a design cholce for thc particular embodiment shown.
First locking portion 126 of seg",6nted teeth 84 is defined by the gensn 'Iy rectangular tip portion thereof and includes linear edge surfaces 132. Plt:ielvbly, linear edge surfaces 132 are substantially parallel to the centerline of teeth ~4. Moreover, the length of linear edge surfaces 132 is selected to e,nended inwardly from the terminal enq ot each tooth 84 to a first l,~ns;lion point. More pr~fe.~bly, the wldth of first locklng portion 126 is selected to ba smaller (I.e., appro,~;", Ely 50%-75%) than the width of locking apertures 86 for tacilitating the flrst or "anti-ratchet" engagemen~ position (see phanlc r" line posltion of Figure 8). Iuler",ediale cammlng portion 130 Ir,'~rconnec1s first locking portion 126 to second locklng portion 128 and Includes a ramped llanv'ti~n surfaces 134 for guiding one set of locklng aperture edge surfaces 136 from Initial enydger"enl with respectivo ones of linear edge surfaces 132 (I.e., the Ranti-ratchet" position) into co". '~l engayer"0"l betwe~n both sets of locking aperture edge surfac~s 136 with both edge surfaces 138 formed on second locking portion 128. In addition, such "camming" movement if not i",r"ed;ale, will occur In response to slight movement of the seat. As shown in Figure 8, camming surfaces 130 extend between the first l,ansition point and a second t,~n ' ~n point located at the outer extent of edge surfaces 138. While camming surfaces 130 are shown to be arcuate, a wlll be appreclaled that other profiles (i.e., linear) are conler"F' ' ç ! which would likewise provide a sultable camming surface.
According to the l~r~r, ed embodiment, edge surfaces 138 of second locking portion 128 are linear and slightly tapered relative to the centerline of teeth 84. The back-angled contour for edge surfaces 138 assists in minimizing resislance to movement of latch 21~9760 plate 80 to the "released" position when seat adjustment Is desirad. Second locking portion 128 terminates at a third l~cnsition polnt with a wldth dimension that is substantlally identical to the overall width of locking apertures 86. As such, a wedging-type frictional contact In the second en~agbr"er,t position acts to inhibit "chucking" movement of the seat. Thus, linear ;
edge surfaces 132 of first locking por~ion 126 are siz0d to facilitate initial interdigitation w3"g ho,i~onlal seat adjustment to retain the seat In the a~justed posltlon while concurrently inhlbitlng false latching or ~ratchetin~" ~f lockiny teeth 84 over locklng aper~ures 86.
The loregc-.,g ~iscussion d'~closes and desc,i~es pr,,~f~r,ed er"~~ 'imbr,ts of a unique Interlockingly iutelfilled track ar,di,ge",bnl and a vertical latching ",echan;~l" for a seat slide devlce. However, one skilled in the art will read31y IGCGgrli~e from such d;scussion, and from the accGmpanying d~ 3ngs and claims, that various changes""Gdilicalions and ~ ~ g vdilalions can be made therein without departing from the spirit and SCOp9 of the invention as defined in the ~ ..ing claims.
