Abstract
An air bag inflator for generating gas to rapidly inflate an air bag includes a housing having spaced-apart opposite end walls with aligned outer peripheral edges, an outer side wall extending between the end walls around the peripheral edges defining an outer chamber for containing gas-generating material and a filter element. The housing also includes an inner side wall extending between the end walls in concentric, centered relation for containing an ignition squib and ignition-enhancing material and provided with ignition ports in communication with the other combustion chamber. The outer side wall is provided with a plurality of ports directing hot products of combustion outwardly to inflate an associated air bag. At least one pair of concentric crimp-formed joints are provided to interconnect the side walls and at least one of the end walls, top or bottom.
