Abstract

At the inflation thereof, an airbag (10) has a three-dimensional shape composed of a front face (11), a back face (12), left and right side faces (13L, 13R), a ceiling face (14), and a bottom face (15). The front face (11) and the back face (12) have a trapezoidal shape in which the upper bottom is wider than the lower bottom. The upper edge of the front face (11) is formed to be wider than the upper edge of the back face (12). At a side collision, the airbag (10) inflates between seats (20L, 20R) so that the airbag face opposed to an occupant (P) falls to the occupant side. This can allow, when the occupant (P) moves to the collision side, the shoulder of the occupant to strike the airbag while simultaneously or substantially simultaneously allowing the head to strike the airbag. An airbag can be provided that blocks, at a side collision, the move due to the impact of the side collision of the occupant in the lateral direction.

Claims

1. An airbag inflating between two seats arranged in a vehicle width direction, wherein

in an inflated status, an outline of a vertical cross section along a vehicle width direction has a shape in which an upper bottom is wider than a lower bottom, and

the airbag has a portion to abut to a ceiling, and the portion is configured to have a high surface friction coefficient so as to suppress a horizontal movement of the airbag.

4. The airbag according to claim 1 or claim 2, wherein the portion that is abutted to the ceiling is treated with a surface roughening.

5. The airbag apparatus according to claim 1 or claim 2, wherein the portion that is abutted to the ceiling is composed of different material having a high friction coefficient from that of other portions of the airbag.

2. An airbag inflating between two seats arranged in a vehicle width direction and that forms, at the inflation thereof, a three-dimensional shape composed of a front face, a back face, left and right side faces, a ceiling face, and a bottom face, wherein

the front face and the back face form a shape in which an upper bottom is wider than a lower bottom, and

the airbag has a portion to abut to a ceiling, and the portion is configured to have a high surface friction coefficient so as to suppress a horizontal movement of the airbag.

3. The airbag according to claim 2, wherein the front face has an upper edge wider than an upper edge of the back face.

6-8. -8. (canceled)

9. An airbag inflating between two seats arranged in a vehicle width direction, wherein

in an inflated status, an outline of a vertical cross section along a vehicle width direction has a shape in which an upper bottom is wider than a lower bottom, and

the airbag inflate without entering a region between surfaces of two seats.
