ABSTRACT:
An air bag module using a tubular inflator uses a different housing, retaining ring, cushion and inflator bracket than are currently used, with the appearance and function of the module not being changed but only the internal components. The inflator is placed in a slotted section of the module housing with the diffuser thereof protruding from the center through a hole in a raised portion of the module housing slotted section, which hole is sized closely to the size of the diffuser. The diffuser extends directly into the module at a 90.degree. angle to the plane surface of the housing. The retaining ring has raised portions in the center thereof to match the raised portion of the module housing, has holes in the raised portions, and has tabs which extend through holes in the cushion and the module housing. The module housing has tabs on the raised portion thereof which extend through holes in the cushion and retaining ring. The cushion uses a rectangular mounting so that the cushion can match the radius of the module housing in the raised portion which goes over the tubular inflator. The retaining bracket extends around the back side of the inflator to hold it in place and includes cover retaining brackets incorporated therein. Studs which hold the module together extend from the retaining ring through holes in the cushion, module housing, and retaining bracket.
