Abstract

An air bag cover is formed of synthetic resin and is connected to and held by the body of a car in a plurality of discontinuous portions thereof along the peripheral edge of an opening formed on the interior side of the car in such a manner that the air bag cover not only can cover an air bag folded in the peripheral edge of the opening on the car interior side, but also, when an air bag main body of the air bag is developed and expanded, can be so opened and moved as to allow the air bag main body to project toward the opening side. The air bag cover further includes a restricting wall which projects toward the body of the car in such a manner that it can connect together these connecting/holding portions while the restricting wall is disposed on the back surface side of the air bag cover, in more particular, on the side of the folded air bag main body that is distant from the opening and on the opening side of connecting/holding portions.

Claims

1. An air bag cover being formed of synthetic resin and connected to and held by a car body, said air bag cover being disposed along a peripheral edge of an opening formed on an interior side of the car body for covering an air bag folded in the peripheral edge of the opening, wherein, when the folded air bag is developed and expanded, the air bag cover can be so opened and moved as to allow the air bag to project toward said opening side, said air bag cover comprising:

a cover main body being disposed along the peripheral edge of the opening;

a plurality of connecting/holding portions being discontinuously disposed on said cover main body; and

a restricting wall projecting from said cover main body toward the car body side to connect together said plurality of connecting/holding portions, said restricting wall being formed on a side of the air bag that is distant from the opening as well as on the opening side of said connecting/holding portions.

2. An air bag cover according to claim 1, wherein a thickness of said restricting wall is set in a range of 1 mm to 4 mm.

3. An air bag cover according to claim 1, wherein said restricting wall is formed by one integral wall.

4. An air bag cover according to claim 1, wherein said restricting wall is formed by a plurality of walls.

5. An air bag cover according to claim 1, wherein the restricting wall is arranged to extend in substantially a longitudinal direction of the cover main body.

6. An air bag cover according to claim 5, wherein the restricting is integrally formed with the cover main body.
