The pyrotechnics in an air cushion inflator are caused to function by the auto ignition device when the device is subjected to a high temperature environment, such as a bonfire, at a temperature of 350° F. (177° C.) in place of in the 650° F. (343° C.) range which would occur if there were no auto ignition device. This enables the use of aluminum for the inflator housing, thereby to minimize weight, the aluminum having sufficient high temperature properties to contain the internal auto ignition pressures at 350° F. (177° C.) but not at 650° F. (343° C.).
1. The combination of an inflator for the generation of a gas to inflate a vehicle passive restraining crash protection bag, and an auto ignition device, said inflator having a housing structure containing a gas generant composition which when ignited generates a gas for the inflation of the crash protection bag, ignition means for igniting said gas generant composition responsively to the onset of a crash of the vehicle in which said inflator is mounted, and filter means, said housing structure having ports therein for the passage of gas generated ...
