1. A vehicle seat, comprising:
- a seat cushion;
a seat back connected to the seat cushion, the seat back including;
a seat pad including a surface configured to support a first upper body of an occupant, who sits on the seat cushion, from a back of the occupant;
a covering including front portion that covers the surface of the seat pad, and a back portion opposite to the front portion; and
an airbag disposed between the front portion and the back portion in a deflated state; and
an inflator connected to the airbag,wherein the inflator is configured to supply an inflation gas into the airbag to transform the airbag from the deflated state to a deployed state in response to a collision,wherein, in the deployed state, the airbag has such a shape that a deployment amount, in a front-back direction, of the airbag near an upper part of the seat back is greater than that near a lower part of the seat back, andwherein the airbag deploys in the seat back in such a way that, in the deployed state, the airbag elastically supports a second upper body of another occupant and elastically receives an impact force applied to a back surface of the seat back.

Abstract
A vehicle seat includes a seat back, and an airbag that deploys in 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 an upper part of the seat back differs from that near a lower part of 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.
