ABSTRACT:
A driver side inflator base for a vehicle safety system 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 a squib of the gas 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.
