Abstract
An occupant restraining inflatable cushion apparatus includes a gas generator used to inflate an inflatable fabric cushion which is packaged about the gas generator in a deflated condition. The cushion and gas generator are connected with a closed end of a housing having diverging side walls. The side walls of the housing have venting apertures. The side wall of the cushion also has apertures which, upon inflation of the air bag, register with the apertures in the housing, allowing aspiration of the air bag through the side walls of the housing. Therefore, direct venting through the air bag into the vehicle occupant compartment is avoided.
