ABSTRACT:
An apparatus (16) includes a canister (72) defining a first hermetically sealed combustion chamber (73). The first combustion chamber (73) contains a source of inflation fluid comprising 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). An initiator assembly (28) is located outside the canister (72). When the initiator assembly (28) is actuated, it ruptures the first end wall (76) of the canister (72). It also projects pyrotechnic combustion products into the first combustion chamber (73) to ignite the body (27) of gas generating material in the first combustion chamber (73). The initiator assembly (28) comprises an electrically actuatable igniter (122) and a booster charge (124) of pyrotechnic material which is separate from the igniter (122). The booster charge (124) is contained in a second hermetically sealed combustion chamber (129) which is defined in part by the first end wall (76) of the canister (72), and in part by a booster cover (130) which is fixed to the canister (72).
