The head rest 156 is then lowered through the central opening 198 until the pin 188 engages one or more of the plateau portions 192 , 194 or ramps 196 and the collar 187 is seated on an upper flat surface 189 of the base 160 . When the head rest 156 is located in its retracted position, opposite sides of the pin 188 are located on each of the upper plateau portions 192 . This position is schematically illustrated in FIG. 15 as position 1 (with only one end of the pin 188 being shown).
- the head rest 156 In order to pivot the head rest 156 to its extended position, the head rest 156 , rod 170 and pin 188 are pivoted about axis C such that the pin 188 rides up each of the ramp portions 196 , as shown in position 2 of FIG. 15. As the pin 108 rides up the ramps 196 , the tips 176 of the rod are raised generally upwardly, which then pulls the retaining tabs 178 generally upwardly in the direction of arrows D in FIG. 11. Accordingly, if the head rest 156 is pivoted only partially to its extended position (as shown in position 2 of FIG. 15) and the head rest 156 is then released, the head rest 156 will return to its retracted position (i.e., position 1 of FIG. 15) as pulled by the retaining tabs 178 .
- the pin 188 clears the ramps 196 and snaps into position on the lower plateau portion 194 , shown as position 3 in FIG. 14. In this position, the head rest 156 is securely retained in the extended position due to the interaction between the pin 188 and the generally vertically-extending face 201 of each ramp portion 196 .
- the head rest 156 is gripped and lifted upwardly until the pin 188 clears the vertical face 201 of the ramp portions 196 , as shown in position 5 of FIG. 15.
- the coupling tabs 172 , 174 bend the retaining tabs 178 upwardly in the direction of arrows D.
- the head rest body 160 may include a pair of limit bars 204 (FIG. 1I) to limit the upward deflection of the retaining tabs 178 .
- the head rest 156 can be pivoted between its extended and retracted position, and is bi-stable.
- the size of the pin 188 and vertical face 201 may be selected such that when the head rest 156 is in its extended position the pin 188 can “ride up” and over the vertical face 201 and into its retracted position when sufficient rotational force is applied to the head rest 156 without being required to lift up the head rest 156 .
- the configuration and operation of the head rest 154 is substantially identical to the head rest described and shown above for head rest 156 .
- the shape and configuration of each ramp 196 may be reversed such that each head rest 154 , 156 is moved from its retracted position to its extended position by the sequence illustrated in FIG. 15.

As shown in FIG. 2, thethigh support 30 may include a pair of support members orrods rod circumferential grooves 36 formed thereon. Theseat pan 18 may include a pair of grippingportions front surface 41 thereof (FIG. 5). Eachgripping portion seat pan tabs rods tabs grooves 36 to lock thethigh support 30 in place relative to theseat pan 18. For example, as shown in FIG. 2, thetabs 46, 48 (only one of which is shown in FIG. 2) of thegripping portion 44 are received in thegroove 36′ to lock thethigh support 30 in place relative to theseat pan 18. Of course, thetabs groove 36′ of therod 32. - The
thigh support 30 may include aprotruding handle portion 50 located on afront surface 52 thereof, thehandle portion 50 defining a hand-receivinggroove 54 located behind the front surface 52 (see FIG. 4). In this manner, a user can grip thehandle portion 50 by sliding the user's fingers behind thehandle portion 50 and into the hand-receivinggroove 54 to grip thethigh support 30 to move thethigh support 30 closer to or further away from theseat pan 18. In this manner, thethigh support 30 may be moved along axis A which extends across the depth of thecar seat 10 between a retracted position, wherein thethigh support 30 is located adjacent to the seat pan 18 (FIG. 1), and any one of an extended position wherein thethigh support 30 is spaced away from seat pan (see, e.g., FIG. 2). In each of the extended positions, as well as the retracted position, thetabs portion grooves 36 to retain thethigh support 30 in place. Thethigh support 30 can be moved to a different position by pushing or pulling on thethigh support 30 with force sufficient to urge thetabs corresponding grooves 36. Thethigh support 30 is then slid closer to or further away from the seat pan until thetabs portion groove 36 to retain thethigh support 30 in place. - As best shown in FIG. 4, each
rod cantilevered coupling prongs coupling prong tapered coupling tip 62 located at an end thereof (also see FIG. 2). In order to couple eachrod thigh support 30, thetips 62 of one set ofcoupling prongs opening 64 in thethigh support 30, and the coupling prongs 58, 60 are pushed into the associatedopening 64. As the coupling prongs 58, 60 are urged into theopening 64, the outer angled surfaces of thetips 62 engage the surfaces of theopening 64, which presses thetips 62 together so that the tips can pass through the associatedopening 64. Once thetips 62 are passed through and emerge on the other side of the opening 40, thetips 62 spring apart to thereby lock therod thigh support 30. - Similarly, in order to couple the thigh support30 to the
seat pan 18, an end of eachrod gripping portions tips 62 are received through theopenings 51 of thebody 14 in a manner similar to that described above for coupling therods thigh support 30. - As best shown in FIGS. 2 and 5, the seat pan may include a pair of
protection panels 70 coupled to and located generally below thethigh support 30. Theprotection panels 70 may be coupled to and extend generally outwardly from theseat pan 18 to provide support to thethigh support 30 when thethigh support 30 is located in one of its extended positions. Theprotection panels 70 may also protect the vehicle seat upon which thebooster seat 10 is located by spacing thethigh support 30 from the vehicle seat. - Although the illustrated
booster seat 10 includes a pair ofcoupling rods corresponding openings 51, thebooster seat 10 may also include only a single coupling rod and opening, or more than two coupling rods and openings. Furthermore, although thecoupling rods thigh support 30 and slidable relative to theseat pan 18, therods seat pan 18 and thethigh support 30 may include the grippingportions rods openings 51 are preferably shaped to correspond to the shape of therods - The
adjustable thigh support 30 enables thethigh support 30 to move outwardly such that thethigh support 30 can be located at a desired extended position. For example, it may be desired to have thethigh support 30 located at an outer end of the thigh of an occupant (that is, located immediately adjacent to the crook of the knee of an occupant), and theadjustable thigh support 30 enables the booster seat to accommodate differently-sized occupants. Thethigh support 30 can also enable thebooster seat 10 to assume a compact condition when thethigh support 30 is in its retracted position. - As shown in FIG. 1, the

Thebody 14 may include a pair of columns of generally vertically-extending openings (not shown), each column of openings extending along an outer edge seat back 16. In order to couple thehead rest assembly 152 to the seat back 16, thehead rest assembly 152 is placed against the seat back 16 such that each of the attachment points 164 is aligned with an opening on the seat back 16. A fastener can be passed through each of the aligned openings of thehead rest assembly 152 and seat back 16 to secure thehead rest assembly 152 to the seat back 16 at the desired height. - The
head rest base 160 may include abelt guide 22 defining aslot 24 therein for receiving a vehicle belt therethrough. Thehead rest assembly 152 may also include a generally triangular-shapedhead rest 156 coupled to thehead rest base 160. Thehead rest 156 may include a generally downwardly extendingrod 170 that is received in thehead rest base 160 to pivotally couple thehead rest 156 to thehead rest base 160. Thehead rest 156 may include acollar 187 located on therod 170. Thehead rest 154 is substantially identical to thehead rest 156. - Each
head rest body 14 and is pivotable about an axis C which extends generally along the height of the body 14 (see FIG. 1). Eachhead rest head rest 154 of FIG. 1) wherein the head rest is generally flush with the seat back 16, and an extended position (head rest 156 of FIG. 1) wherein the head rest forms an angle with the seat back 16. - As shown in FIG. 11, the
rod 170 ofhead rest 156 may include a pair ofcantilevered coupling prongs coupling prong tip 176. Thehead rest base 160 may include a pair of opposed cantilevered retainingtabs 178 defining anopening 180 therebetween. In order to couple therod 170 to thehead rest base 160, thetips 176 of eachcoupling prong opening 180, and therod 170 andhead rest 156 are urged downwardly, which urges thetips 176 together so that thetips 176 can fit through theopening 180. Once thetips 176 emerge on the opposite side of theopening 180, thetips 176 spring apart to couple therod 170 andhead rest 156 to thehead rest base 160. The retainingtabs 178 andtips 176 may be shaped and located such that after thehead rest 156 is coupled to thehead rest base 160, the retainingtabs 178 pull therod 170 andhead rest 156 generally downwardly; in other words, once thecoupling flanges opening 180, thecoupling flanges tips 176 may pull the retainingtabs 178 slightly upwardly in the direction of arrow D, as will be discussed in greater detail below. - The
head rest assembly 152 may include a retaining mechanism, generally designated 186, that can maintain thehead rest 156 in its retracted and extended position. As shown in FIG. 14, theretaining mechanism 186 may include apin 188 that is coupled to, and extends generally transversely to, therod 170 of thehead rest 156. Thepin 188 preferably protrudes from both sides of therod 170, and is shaped and located to be received in arecess 190 formed in the head rest base 160 (see FIGS. 12 and 13). Therecess 190 may include acentral opening 198, a pair of opposedupper plateau portions 192 and a pair of opposedlower plateau portions 194. Eachupper plateau portion 192 may be located slightly above the associatedlower plateau portion 194. Therecess 190 may further include a pair oframps 196, with eachramp 196 being located between an associated upper 192 and lower 194 plateau portion. - In order to mount the
head rest 156 to the associatedbase 160, thehead rest 156 is placed into thehead rest base 160 such that therod 170 is passed through the central opening 198 (see FIG. 16). Thehead rest 156 is then lowered through thecentral opening 198 until thepin 188 engages one or more of theplateau portions ramps 196 and thecollar 187 is seated on an upperflat surface 189 of thebase 160. When thehead rest 156 is located in its retracted position, opposite sides of thepin 188 are located on each of theupper plateau portions 192. This position is schematically illustrated in FIG. 15 as position 1 (with only one end of thepin 188 being shown). In order to pivot thehead rest 156 to its extended position, thehead rest 156,rod 170 and pin 188 are pivoted about axis C such that thepin 188 rides up each of theramp portions 196, as shown inposition 2 of FIG. 15. As thepin 108 rides up theramps 196, thetips 176 of the rod are raised generally upwardly, which then pulls the retainingtabs 178 generally upwardly in the direction of arrows D in FIG. 11. Accordingly, if thehead rest 156 is pivoted only partially to its extended position (as shown inposition 2 of FIG. 15) and thehead rest 156 is then released, thehead rest 156 will return to its retracted position (i.e.,position 1 of FIG. 15) as pulled by the retainingtabs 178. - Upon sufficient rotation of the
head rest 156, thepin 188 clears theramps 196 and snaps into position on thelower plateau portion 194, shown asposition 3 in FIG. 14. In this position, thehead rest 156 is securely retained in the extended position due to the interaction between thepin 188 and the generally vertically-extendingface 201 of eachramp portion 196. In order to return thehead rest 156 to its retracted position, thehead rest 156 is gripped and lifted upwardly until thepin 188 clears thevertical face 201 of theramp portions 196, as shown inposition 5 of FIG. 15. As thehead rest 156 androd 170 are lifted, thecoupling tabs tabs 178 upwardly in the direction of arrows D. Thehead rest body 160 may include a pair of limit bars 204 (FIG. 1I) to limit the upward deflection of the retainingtabs 178. Once thehead rest 156 and pin 188 are lifted sufficiently such that thepin 188 clears thevertical faces 201 of the ramps 196 (as shown inposition 5 of FIG. 15), thehead rest 156 may then be pivoted to its retracted position, as illustrated inposition 6 of FIG. 15. - In this manner, the
head rest 156 can be pivoted between its extended and retracted position, and is bi-stable. The size of thepin 188 andvertical face 201 may be selected such that when thehead rest 156 is in its extended position thepin 188 can “ride up” and over thevertical face 201 and into its retracted position when sufficient rotational force is applied to thehead rest 156 without being required to lift up thehead rest 156. The configuration and operation of thehead rest 154 is substantially identical to the head rest described and shown above forhead rest 156. Furthermore, it should be understood that the shape and configuration of eachramp 196 may be reversed such that eachhead rest - Having described the invention in detail and by reference to the preferred embodiments, it will be apparent that modifications and variations thereof are possible without departing from the scope of the invention.
