Abstract
An inflator (10) for inflating an air bag (12) includes an outer housing (40). A hermetically sealed canister (90) containing disks (110) of gas generating material is located in the outer housing (40). The canister (90) also contains an annular auto ignition packet (150) containing an auto ignition material (164) having an ignition temperature below the ignition temperature of gas generating material in disks (110). The auto ignition packet (150) extends around a base (138) of an igniter (99). The auto ignition packet (150) is disposed adjacent to a lower end wall (46) of the inflator housing (10) opposite from an end wall across which the folded air bag extends. Consequently, the air bag does not insulate the auto ignition packet (150) from the interior of the vehicle in which the inflator is disposed.
