ABSTRACT:
An inflatable vehicle passenger restraint system has an inner and an outer air bag which are both coupled to a manifold which provides inflation gas produced by a gas generator. When the gas generator is activated, inflation gas quickly inflates the smaller inner air bag and simultaneously inflates the outer air bag at a slightly slower rate, thereby more fully protecting an out of position occupant by filling the outer air bag with a relatively slow fill rate as compared to the inner air bag. The inflatable restraint system preferably includes a control arrangement for controlling the deflation rate of at least one of the inner and outer air bags.
