ABSTRACT:
A multi-stage inflator including a housing at least in part defining first and second combustion chambers each containing a quantity of gas generant reactable to form respective product gases. The inflator includes first and second initiators each operatively associated with a respective one of the combustion chambers in reaction initiating communication with at least a portion of the quantity of the gas generant therein contained such that upon actuation the gas generant ignites to form product gas. The second combustion chamber has an exit opening to allow product gas to exit from the second combustion chamber and into the first combustion chamber. The housing includes at least one discharge opening to permit gas to exit the housing and an end wall and wherein both the first and the second initiators are connected.
