Vehicle seat
First Claim
1. A vehicle seat, comprising:
- a seat back covered with a covering;
a seat back frame disposed in the seat back;
an airbag that is disposed in the seat back between a reaction-force-receiving member and a back portion of the covering, and that deploys in the seat back between the reaction-force-receiving member and the back portion of the covering; and
the reaction-force-receiving member that is disposed in back of a seat pad and is disposed in front of the air bag, the reaction-force-receiving member being configured to be deformed, in a forward direction of a vehicle, to protrude into an area that is occupied by the seat pad before the air bag deploys, and the reaction-force-receiving member controls a deployment direction of the airbag by receiving a reaction force generated when the airbag deploys such that, in the forward direction of the vehicle, a width of the seat pad decreases after the air bag is deployed,wherein the airbag deploys in the seat back in such a way that, after having deployed, the airbag elastically supports an upper body of an occupant and elastically receives an impact force applied to a back surface of the seat back by a body of a seated person on a rear seat, andwherein the reaction-force-receiving member comprises an elastic support member that is disposed across the seat back frame.

Abstract
A plurality of elastic support members extends across a seat back frame that forms a skeleton of a seat back of the vehicle seat. A seat pad is disposed on the front sides of the elastic support members. An airbag is disposed between the elastic support members and a back portion of a covering in a deflated state. After having deployed, the airbag has such a shape that a deployment amount, in a front-back direction, of the airbag near a side of the seat back is greater than that near a center of the seat back. In a collision or the like, the airbag deploys in the seat back in such a way that, after having deployed, the airbag elastically supports an upper body of an occupant and elastically receives an impact force applied to a back surface of the seat back.
