Inflator

摘要

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.
