Abstract

An apparatus (10) for inflating an air bag includes a container (12) for holding a stored supply of gas under pressure. A body (20) of gas generating material is disposed in a housing (22). A cup shaped closure member (24) blocks a flow of gas through an annular array of passages (28) formed in an end wall (58) of the container (12). The cup shaped closure member (24) has a frangible section (176). Upon ignition of the body (20) of gas generating material, the gas applies pressure against an end wall (166) of the closure member (24) to break the frangible section (176) of the closure member. The pressure applied by the gas against the end wall (166) of the cup shaped closure member (24) moves the closure member toward an opposite end of the container (12). Gas flows from the container (12) through the openings (28) in the end wall of the container into a diffuser (36). The diffuser (36), closure member (24) and housing (22) which holds the body (20) of gas generating material are all connected to the end wall (58) of the container (12).
