Abstract
Abstract An air bag structure for an automotive vehicle is mounted on an instrument panel in front of a passenger seated on a front seat of the vehicle. The air bag structure includes a casing enclosing an inflator and air bag. The casing is formed with a plurality of aspiration holes, through which air is introduced into the air bag when the air bag is inflated by an ignition of inflator. A cover member surrounds and covers the casing. The cover member is spaced from the casing by a predetermined distance, so that an air passage is formed between the cover member and the casing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
An air bag structure for an automotive vehicle which is mounted on an instrument panel in front of a passenger seated on a front seat of the vehicle, comprising: an inflator for generating gas, an air bag for receiving the gas generated by the inflator, a casing for enclosing the inflator and the air bag, said casing including a plurality of aspiration holes formed therein through which air is introduced into the air bag when the air bag is inflated by ignition of said inflator, and a cover member for surrounding and covering the casing, said cover member being spaced from the casing so that air is introduced into the air bag, through the aspiration holes, from an air passage between the cover member and the casing.
Claim 2
Dependent Claim
