ABSTRACT:
An inflator (20) for inflating a vehicle air bag (22) comprises a housing (42, 44) defining a toroidal chamber (46) containing an inflation fluid for inflating the air bag. The toroidal chamber (46) extends around a central axis (A) of the housing (42, 44). A rupturable closure member (102) is fixed to the housing (42, 44) for blocking fluid communication from the toroidal chamber (46) to the air bag (22) when the closure member (102) is in an unruptured condition. The closure member (102) is located along the central axis (A) of the housing (42, 44). A first actuatable initiator (142) is supported in the housing (42, 44). The first initiator (142), when actuated, effects the rupture of the closure member (102) to allow inflation fluid to flow from the toroidal chamber (46) to the air bag (22). A second initiator (182) is also supported in the housing (42, 44). An ignitable material (222) is ignited by the second initiator (182) to effect an increase in the temperature and pressure of the inflation fluid flowing from the toroidal chamber (46).
