Stamped driver inflator base
First Claim
1. A housing construction for a gas generating inflator comprising:
- a diffuser comprising a first shell having a plurality of concentric chambers, each chamber having a wall;
a base comprising a second shell stamped from a sheet of aluminum, the stamped base including a central axis, a plurality of stamped concentric rings extending upwardly from a bottom of the base, said concentric rings being spaced from said central axis, an interface attachment flange for mounting the inflator, and a squib pocket extending about the central axis of said base for holding a squib of the inflator;
means for attaching the concentric rings of the base with a respective wall of each of the chambers; and
means for securing the squib within the squib pocket of the base, the means for securing having opposed ends, one end engaging the squib and another end engaging an outer surface of a side wall of the squib pocket.

Abstract
A driver side inflator housing for a vehicle safety system which includes a base which is stamped from a thin sheet of aluminum The base includes a central axis, a plurality of stamped concentric rings extending upwardly from a bottom of the base and spaced from the central axis. An interface attachment flange is provided for mounting the inflator, and a squib pocket extending about the central axis of the base is capable of holding the squib of the gas generating inflator. The concentric rings, attachment flange and squib pocket are all formed during the stamping of the base; thus excessive machining is not required. Only minor machining is necessary to complete the base. The base of the present invention is designed to reduce the overall inflator cost, while maintaining the processing capability and quality of current bases.
