Abstract
A vehicle inflatable crash protection bag inflator. The inflator housing comprises two structural components which are welded together by only two welded joints to define an inner or combustion chamber containing gas generant material and an outer or diffuser chamber. An igniter tube is disposed in the combustion chamber free of attachment to one of the structural components and is press fit or otherwise suitably attached to a mounting post on the other structural component. The igniter tube is perforated and wrapped with a foil whereby the igniter material is disposed in direct contact with a squib to better ensure ignition thereof. Alternatively, the igniter tube and igniter material may be eliminated and the gas generant material disposed in direct closely surrounding relation to the squib. The housing is composed of aluminum, and the inflator has a minimum weight and size.
