Abstract
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.degree. F. (177.degree. C.) in place of in the 650.degree. F. (343.degree. 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.degree. F. (177.degree. C.) but not at 650.degree. F. (343.degree. C.).
