DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side support device for a vehicle seat, and more particularly, to a seat cushion, and a seat back provided at the rear of the seat cushion so as to be able to rotate back and forth through a reclining mechanism. The present invention relates to a vehicle seat side support device having a side support device provided between a side rear portion of a seat cushion and a lower side portion of a seat back.

[0002]

2. Description of the Related Art Conventionally, a vehicle seat is provided with a front-rear slide mechanism, a reclining mechanism, a side support device, and the like, and adjusts the front-rear position and the angles of forward and backward tilt according to the physique and preference of a seated person. The safety is improved by improving the supportability of the occupant.

As shown in FIG. 7, a vehicle seat 1 has a seat back 3 attached to a seat cushion 2 by a reclining mechanism 5 such that the seat back 3 can be tilted back and forth. An arm 5b is pivotally supported on a base 5a of the reclining mechanism 5 so as to be rotatable. A side support 2 a is provided on a side portion of the seat cushion 2, and a side support 3 a is provided on a lower side portion of the seat back 3.

[0004]

Therefore, in the conventional vehicle seat 1, since the reclining mechanism 5 causes the seat back 3 to tilt forward, the shapes of the seat cushion 2 and the side supports 2a and 3a of the seat back 3 are limited. If the desired supportability cannot be obtained, and the side supports 2a and 3a of the seat cushion 2 and the seatback 3 are formed large, the seatback 3 cannot be sufficiently tilted forward. there were.

[0005] Further, the rear side of the seat cushion 2 and
If the side support device is fixedly provided between the seat back 3 and the lower part of the side, the getting on and off property is poor, and the welding of the side frame, the tearing of the trim cover, and the like at the time of getting on and off, and the collision of a vehicle or the like occur. In the event of an accident or the like, there is a possibility that the side support device may become an obstacle when the occupant escapes from the vehicle seat.

SUMMARY OF THE INVENTION An object of the present invention is to improve the occupant's getting on and off, improve the occupant's supportability, sufficiently tilt the seat back forward, and quickly move the occupant out of the vehicle in the event of an accident. An object of the present invention is to provide a vehicle seat side support device which can be rescued and has excellent safety.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a vehicle seat side support device according to claim 1 is provided with a seat cushion and a reclining mechanism behind the seat cushion. A seat back provided rotatably forward and backward, and a side support device for a vehicle seat provided with a side support device between a rear side of a seat cushion and a lower side portion of the seat back, wherein the reclining mechanism is provided. A fixing bracket is fixed to the base side of the bracket, and a side bracket is fixed to the fixing bracket, and the side plate slides between the support position where the side plate protrudes obliquely upward and the boarding / alighting position where the side plate moves obliquely downward. Movably arranged, with the pad material covered by the trim cover on the side plate Wherein the detachably attached.

According to a second aspect of the present invention, there is provided a vehicle seat side support device, wherein a fixed bracket is fixed to a base side of a reclining mechanism, a side bracket is fixed to the fixed bracket, and a side plate is fixed to the side bracket. Slidably provided, a drive mechanism including a drive motor between the side bracket and the side plate, and a guide portion is provided, from a support position where the side plate projects obliquely upward with respect to the side bracket, The drive mechanism is provided so as to be slidable between the boarding position and the boarding position which has moved obliquely downward, and the pad material is attached to the side plate in a state covered with a trim cover.

[0009]

According to the side support device for a vehicle seat according to the first aspect of the present invention, the side plate mounted with the pad material covered with the trim cover projects obliquely upward with respect to the side bracket. It is slidably disposed between the boarding position and the boarding position moved diagonally downward from the position, so that the side plate can be lowered when the occupant gets on and off or the seat back leans forward, and when the occupant is seated. The occupant can be reliably supported by raising the side plate.

Further, since the pad material is detachably attached to the side plate while being covered with the trim cover, the pad material is removed in the event of a collision of a vehicle or the like to secure a space and the occupant can be quickly taken out of the vehicle. It can be rescued.

According to the vehicle seat side support device of the second aspect of the present invention, a drive mechanism having a drive motor between the side bracket and the side plate and a guide portion are provided, and Since the side plate is slidably provided by the drive mechanism between the support position where the side plate protrudes obliquely upward with respect to the side bracket and the getting on / off position which moves obliquely downward,
The occupant can get on and off easily, the seat back can be sufficiently tilted forward, and the supportability can be improved.
