Abstract
A gas generator contains a housing containing an end closure assembly. An annular end closure is fixed within an annular igniter retainer thereby forming an annular wall for retention of an associated igniter. A first base portion of the annular end closure, and a second base portion of the annular igniter retainer are fixed together, by projection-welding for example, thereby facilitating a cost-effective seal about the igniter when assembled therewith.
