ABSTRACT:
An inflator (20, 220) for inflating an air bag comprises a housing (22, 222) having a central axis (A, A1). The housing (22, 222) defines a substantially toroidal chamber (46, 246) disposed around the central axis (A, A1). An outlet opening (64, 264) in the housing (22, 222) provides fluid communication between the toroidal chamber (46, 246) and the air bag. A mixture of gases is stored in the toroidal chamber (46, 246) and comprises a combustible gas and a substantially noncombustible inflation gas for inflating the air bag. A closure (102, 302) of the housing (22,222) has a first condition blocking the flow of gas from the toroidal chamber (46, 246) to the outlet opening (64, 264). The closure (102, 302) has a second condition allowing the flow of gas from the toroidal chamber (46, 246) to the outlet opening (62, 262). An actuatable igniter (146, 346), upon actuation, causes the closure (102, 302) to change from the first condition to the second condition and ignites the combustible gas of the mixture of gases.
