ABSTRACT:
An improved air cushion restraint system utilizes a gas flow-regulating valve having an inner membrane, an outer membrane, a pucker formed therebetween, and a flow passage from the air bag inflation chamber to the pucker for expulsion through an outer membrane aperture. The inner membrane is extensible in response to occupant impact with the air bag which exceeds a threshold value such that the inner membrane extends in response to such load where it is brought into nested engagement with the outer membrane pucker which flow restricts the aperture and stiffens the air bag.
