The airbag cushion has a passive venting system that remains open or transitions to a closed position depending on the impact of the airbag with an occupant and the position of the occupant. The venting system self closes upon deployment when an occupant is not out of position but remains open when an occupant is out of position. The venting system self closes due to cushion membrane tension.

Safety venting with passively closeable vents

An airbag cushion has two chambers to permit the front chamber to inflate less rapidly than the back chamber for cushioning the head of an occupant in a vehicle with less force than the chest of an occupant is cushioned by the back chamber.

Dual chamber airbag cushion

An airbag cushion has two chambers to permit the front chamber to inflate less rapidly than the back chamber for cushioning the head of an occupant in a vehicle with less force than the chest of an occupant is cushioned by the back chamber. The front chamber has at least one safety vent.

An improvement in inflatable restraint air bag module assemblies with non-symmetric gas output inflators wherein a diffuser of specific design and in cooperation with the reaction canister results in reduced air bag deployment skewness.

Reduced airbag deployment skewness with non-symmetric gas output

A valve is provided in an automotive airbag module housing to relieve any excessive pressure in the module housing as may occur during deployment of an airbag. The valve is formed entirely from material in the housing by punching out openings in the housing material. The invention is applicable to airbag inflating devices in which the inflator is enclosed entirely within the module housing and is particularly useful in passenger side airbag inflation devices.
