ABSTRACT:
A new and useful vehicle air bag module design and new assembly techniques are designed specifically for automating the process of assembling an air bag module. The air bag module includes a reaction can which has a main body defining a cavity and an air bag opening, an external flange extending away from the air bag opening, and an inflator-receiving slot formed in part of the main body. A folded air bag having a gas inlet opening is at least partially disposed in the cavity. A retention device is integral with the air bag around the periphery of the gas inlet opening and is disposed adjacent the external flange on the reaction can. The inflator has a cylindrical housing and an integral coupling structure. The cylindrical housing extends partially through the inflator-receiving slot and includes a portion disposed within said cavity and a portion disposed outside said cavity. A first set of fasteners connects the coupling structure of the inflator with a portion of said main body of said reaction can. A second set of fasteners connects the retention device with the external flange on the reaction can. The reaction can, which may be either aluminum or steel, is formed as a monolithic structure by deep drawing techniques.
