Description
- This non-provisional application claims priority from Japanese Patent Application No. 2008-012806 filed on Jan. 23, 2008, the discloser of which application is hereby incorporated by reference into this application in its entirety for all purposes.
- A technique disclosed in the present specification relates to an armrest structure for a vehicle seat in which an armrest is mounted on the outboard side of a seat back.
- It is general to provide an armrest at a side door in a conventional armrest structure for a vehicle seat. In a side door of a vehicle disclosed in, for example, Japanese Unexamined Patent Application Publication 2006-56424, a support shaft serving as a swinging support axis is provide at the lower side part of a support member (the armrest) to allow the armrest to be capable of swinging and shifting about the support shaft as the support axis.
- In the conventional armrest structure for a vehicle seat, however, the armrest is provided at the side door to necessitate operation for accommodating the armrest in operating to open/close the side door, which is laborious. Automation of this operation makes the structure of the side door more complicated than a case with an armrest merely provided at a resin-made trim panel and increases its weight to make the opening/closing operation difficult.
- While on the other hand, when the armrest is provided at a seat without narrowing the width of the seat, a hand or the like may be caught between the side door and the armrest in opening/closing the side door.
- The present invention has been made in view of the foregoing and has its object of securely preventing a hand and the like from being-caught by an armrest in opening/closing a door in a simple structure with no narrowing of the width of a seat involved.
- To attain the above object, an armrest provided outboard of a seat back is arranged close to a door trim panel and is made capable of moving inboard.
- Specifically, an armrest structure includes: a mounting portion provided on an outboard side in a car width direction of a seat back; an armrest mounted at the mounting portion; and a door trim panel provided outboard of the seat back, wherein the armrest is arranged close to the door trim panel and is movable inboard upon receipt of an inboard load.
- With the above arrangement, the armrest moves inboard upon receipt of an inboard load caused when a hand or the like intervening between the door trim panel and the armrest pushes the armrest in opening/closing the door. Hence, the hand or the like is not caught even though the width of the seat is not reduced.
- The door trim panel may be provided at a sliding door and is located close to an outboard surface of the armrest when the sliding door is closed.
- The above arrangement eliminates the need to form the armrest at the door trim panel of the sliding door to lead to reduction in the amount of outboard ejection in opening of the sliding door and to eliminate the need to form in the door trim panel a large armrest releasing clearance for preventing a hand and the like from being caught. Hence, the width of the seat is need not to be narrowed to increase the degree of freedom of design.
- The armrest may include a swing mechanism capable of swinging inboard about the mounting portion as a center upon receipt of the inboard load, and the swing mechanism may include a biasing member for always pushing back the armrest outboard.
- With the above arrangement, when no inboard load is applied, the armrest returns self-operatively to the original position by the operation of the biasing member, thereby eliminating the need to return the armrest manually.
- The swing mechanism may be mounted at the seat back, and the armrest is provided at the swing mechanism.
- In the above arrangement, it is unnecessary to provide the swing mechanism at the armrest to lead to reduction in size and weight of the armrest, thereby facilitating its swinging.
- The armrest may be mounted at the swing mechanism so as to be capable of turning vertically relative to the swing mechanism.
- In the above arrangement, vertical turning of the armrest does not accompany turning of the swing mechanism. Hence, the armrest can swing smoothly when a load in the horizontal direction is applied regardless of the turning position of the armrest.
- The swing mechanism may include: a base plate mounted at a seat back frame; and a swing plate pivotally supported by the base plate so as to be capable of swinging inboard relative to the base plate, wherein the armrest is mounted at the swing plate so as to be capable of turning vertically relative to the base plate.
- With the above arrangement, the swing plate swings relative to the base plate mounted at the seat back frame to cause the armrest to swing relative to the seat back frame. Vertical turning of the armrest means mere turning of the arrest relative to the swing plate and does not cause the swing mechanism to turn. Hence, the armrest is prevented from unintentional inboard swinging at vertical turning of itself and can swing smoothly upon receipt of a load in the horizontal direction regardless of the turning position of the armrest.
- The armrest may include a cushion while the seat back may include another cushion, wherein the armrest is mounted at the mounting potion so as to be in contact at an inboard surface thereof with an outboard surface of the seat back, and the cushion of the armrest and the cushion of the seat back are in contact with each other before the mounting portion.
- With the above arrangement, the mounting portion to which the armrest and the seat back are mounted is not covered with any cushions to reduced the width of the seat as a whole and to facilitate swinging of the armrest by deforming the cushion of the armrest and the cushion of the seat back.

-
FIG. 1 shows the interior of a passenger compartment of a vehicle having anarmrest structure 1 for avehicle seat 2 in the present embodiment, wherein thevehicle seat 2 is composed of three rear seats connected in series. The three rear seats are independent of each other and are capable of sliding back and forth relative to afloor plate 3, and anarmrest 4 is provided on each outboard side in the car width direction of thevehicle seat 2. -
FIG. 2 toFIG. 4 show in enlarged scales one of the rear seats as the right side part of thevehicle seat 2. On each outboard side of thevehicle seat 2, a slidingdoor 5 is arranged, which includes aninner panel 5 a, anouter panel 5 b, and adoor reinforcement 5 c. The inboard surface of theinner panel 5 a is covered with adoor trim panel 6 made of resin or the like. The slidingdoor 5 is opened by sliding it once outward and sliding it rearward then. When the slidingdoor 5 is closed, thedoor trim panel 6 is located close to the outboard surface of thearmrest 4. Since thearmrest 4 is unnecessary to be provided at thedoor trim panel 6, thedoor trim panel 6 has a simple structure including less protrusions other than a slidingdoor handle portion 6 a. Each rear seat includes therebelow asliding mechanism 2 a fixed to thefloor plate 3 to be allowed to slide back and forth. - The
armrest 4 is capable of moving inboard upon receipt of an inboard load, which is a significant feature of the present embodiment. Specifically, as shown inFIG. 5 , which shows the left side part of thevehicle seat 2, aseat back 7 of a left rear seat of thevehicle seat 2 is so composed that aseat back frame 7 a as a framework formed of a cylindrical pipe and a steel plate is covered with aseat cushion 7 b. Thearmrest 4 is mounted at the steel plate on the outboard side in the car width direction of theseat back frame 7 a. As shown inFIG. 8 , at amounting portion 8 of theseat back 7, aswing mechanism 10 is provided which is capable of swinging inboard about themounting portion 8 as a center upon receipt of an inboard load. - As shown in
FIG. 6 , theswing mechanism 10 includes abase plate 11 mounted at theseat back frame 7 a. Thebase plate 11 is bent outboard at the upper and lower parts thereof to form bent portions, and a throughhole 11 a is formed in each of these bent portions. Aswing plate 12 is supported by thebase plate 11 pivotally to be capable of swinging inboard (horizontally). Theswing plate 12 is bent inboard at upper and lower parts thereof to form bent portions, and a throughhole 12 a is formed in each of these bent portions. Aswing pin 13 is fitted from below in each of the throughholes 11 a and the throughholes 12 a with them aligned, and anut 14 is fastened from above. Atorsional coil spring 15 as a biasing member is fitted around theswing pin 13. Though a detailed mounting structure of thetorsional coil spring 15 is not shown, thetorsional coil spring 15 includes a catch formed at one end thereof and a catch formed at the other end thereof. In a state that thetorsional coil spring 15 is wound up from an original natural state (in a state that the bias force in a direction in which the winding is released applied), the catch at the one end is engaged with a hole, a notch, or the like formed in thebase plate 11 while the catch at the other end is engaged with a hole, a notch, or the like formed in theswing plate 12. Thetorsional coil spring 15 always pushes back thearmrest 4 outboard. As shown inFIG. 8 , astopper 12 b is formed in the rear end part of theswing plate 12. Thestopper 12 b comes in contact with the outboard surface of thebase plate 11, thereby restricting the swinging range of theswing plate 12. - From the outboard surface of the
swing plate 12, anarmrest supporting shaft 16 and a turningrange restricting pin 17 are protruded. As shown inFIG. 7 andFIG. 8 , anarmrest frame 18 in a angular C-shape in section of which the lower part is opened is mounted at theswing plate 12. A supportshaft insertion hole 18 a as a through hole is formed in each side plate of thearmrest frame 18 so as to allow thearmrest supporting shaft 16 to pass therethrough. An arc-shapedpin hole 18 b is formed in the inboard side plate so as to receive the turningrange restricting pin 17. Thearmrest supporting shaft 16 is inserted in each supportingshaft insertion hole 18 a with aspacer 19 intervening around thearmrest supporting shaft 16 while the turningrange restricting pin 17 is inserted in thepin hole 18 b, and a tip end screw part of thearmrest support shaft 16 is fastened with anut 20 and aspring washer 21. Whereby, thearmrest 4 is mounted at theswing plate 12 to be capable of vertically turning relative to theswing plate 12. Vertical turning of thearmrest 4 means only turning thereof relative to theswing plate 12 and causes no turning of theswing mechanism 10 itself. This prevents unintentional inboard swinging of thearmrest 4 in vertical turning of thearmrest 4. - In the
armrest 4, a part of thearmrest frame 18 other than the vicinity of the mountingportion 8 is covered with anarm cushion 4 a. Thearmrest 4 in this state is mounted at the mountingportion 8 so as to be in contact at the inboard surface thereof to the outboard surface of the seat back 7, so that theseat cushion 7 b and thearm cushion 4 a are in contact with each other before the mountingportion 8. Theseat cushion 7 b and thearm cushion 4 a are thus provided at a part of the seat back 7 except the mountingportion 8 to which thearmrest 4 and the seat back 7 are mounted, thereby reducing the total width of theseat 2. - Provision of the
armrest 4 at the seat back 7 means that it is unnecessary to form thearmrest 4 at the doortrim panel 6 of the slidingdoor 5, thereby reducing the amount of outboard ejection in opening the slidingdoor 5 and eliminating the need to form a large armrest releasing clearance in the doortrim panel 6. Hence, the degree of freedom in design increases. - —Operation—
- An operation of the
armrest structure 1 for a vehicle seat in accordance with the present embodiment will be described next. - There are two cases in closing the sliding
door 5, namely: the case where a passenger sitting on theseat 2 closes the slidingdoor 5; and the case where a person outside the vehicle closes the slidingdoor 5. Particularly, in the latter case, a passenger sitting on theseat 2 may put on his/her arm on thearmrest 4. When the slidingdoor 5 is closed in such a state, the doortrim panel 6 may push the passenger's hand if the hand is put between the doortrim panel 6 and thearmrest 4. If so, thearmrest 4 is pushed, namely, receives an inboard load, thereby causing theswing plate 12 to swing inboard relative to thebase plate 11 mounted at the seat backframe 7 a. This causes thearmrest frame 18 to swing in the direction indicated by open arrows in the drawings relative to the seat backframe 7 a to deform theseat cushion 7 b and thearm cushion 4 a. Thus, thearmrest 4 swings inboard in this way to prevent the passenger's hand from being caught by the slidingdoor 5. - The
armrest 4 is turned vertically according to the posture of a passenger. Such vertical turning of thearmrest 4, however, causes no turning of theswing mechanism 10. Therefore, thearmrest 4 can swing smoothly upon receipt of a load in the horizontal direction regardless of the turning position of thearmrest 4. Theswing mechanism 10 is provided at the seat back 7 rather than at thearmrest 4, and thearmrest 4 is mounted at theswing mechanism 10. This leads to compaction and weight reduction of thearmrest 4, thereby facilitating swinging and vertical turning of thearmrest 4. - When an inboard load ceases, namely, when a passenger removes his/her hand from the
armrest 4, or so, thetorsional coil spring 15 returns thearmrest 4 self-operatively to the original position. - In the
armrest structure 1 for thevehicle seat 2 of the present embodiment, thearmrest 4 mounted at the mountingportion 8 on the outboard side of the seat back 7 is arranged close to the doortrim panel 6 and is allowed to move inboard upon receipt of an inboard load. Hence, a hand and the like is securely prevented from being caught by thearmrest 4 in opening/closing the door in such a simple structure with no narrowing of the width of theseat 2 involved. - The above embodiment may employ any of the following structures.
- The
armrest 4 is provided at each side of theseat 2 of the three rear seats connected in series in the above embodiment but may be provided at each side of a bench seat. Wherein, in a case of the three seats connected in series which can slide independently of each other, the total width thereof is great, and therefore, the present invention can exhibit the effects prominently. Thearmrest 4 may be provided on the outboard side of the front passenger seat. - The above embodiments are essentially preferable examples and are not intended to limit each scope of the present invention, applicable subject, and use.
