Abstract

A vehicle seat includes a seat back, and an airbag that deploys in the seat back. 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. 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.

Claims

1. A vehicle seat, comprising:

a seat back; and

an airbag that deploys in the seat back,

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, and

wherein, 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.

2. The vehicle seat according to claim 1, wherein, after having deployed, the airbag has such a shape that a deployment amount, in the front-back direction, of the airbag near an outer side of a vehicle is greater than that near an inner side of the vehicle.

3. The vehicle seat according to claim 1, wherein, after having deployed, the airbag has such a shape that a deployment amount, in the front-back direction, of the airbag near an inner side of a vehicle is greater than that near an outer side of the vehicle.
