Inflator for air-bag

A gas generator or inflator (10) preferably contains a housing (12) formed from welding a cap (14) and a base (16) in nested and coaxial relationship. Welding a first wall (15) of the cap (14) with an adjoining and substantially coextensive second wall (17) of the base (16) forms a structural girth. An annulus (36) is preferably formed centrally within the cap (14) thereby providing a seat for an igniter mount (22). An igniter mount (22) is fixed within the annulus (36), and houses an igniter (18) fixed therein. Each gas exit aperture (34) of the base (16) fluidly communicates with at least one corresponding gas exit aperture (32) of the cap (14).
