ABSTRACT:
An apparatus (16) includes a canister (72) defining a hermetically sealed combustion chamber (73). The combustion chamber (73) contains a source of inflation fluid in the form of a body (27) of ignitable gas generating material. The canister (72) has a cylindrical configuration with a longitudinal central axis (79) and first and second opposite end walls (76) and (78). The end walls (76) and (78) have predetermined rupturable portions (82) and (90) extending across the axis (79). An initiator assembly (28) is located outside the canister (72). When the initiator assembly (28) is actuated, it ruptures the rupturable portion (82) of the first end wall (76). It also projects pyrotechnic combustion products into the combustion chamber (73) along the axis (79) to ignite the body (27) of gas generating material in the combustion chamber (73). The rupturable portion (90) of the second end wall (78) is rupturable under a predetermined inflation fluid pressure force acting outward from the combustion chamber (73).
