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).

An apparatus for use in inflating a vehicle occupant restraint, said apparatus comprising: a container for holding a supply of gas; surface means for defining a gas discharge opening for directing gas from said container; a quantity of pressure producing material, said quantity of pressure producing material being ignitable to produce pressure; said container having a closure member blocking said gas discharge opening and at least partially enclosing said quantity of pressure producing material, said closure member including a breakable portion adjacent to said discharge opening, a side wall portion extending from said breakable portion and at least partially enclosing said quantity of pressure producing material, and an end wall portion connected with said side wall portion of said closure member; and igniter means for igniting said quantity of pressure producing material to create pressure against said end wall portion of said closure member to break said breakable end portion of said closure member and to move at least said side wall portion and said end wall portion of said closure member away from said discharge opening to enable gas to flow through said discharge opening toward the vehicle occupant restraint.
