초록

An autoigniting composition comprising lead thiocyanate Pb(SCN).sub.2 as the fuel, a chlorate as the oxidizer and optionally, a binder and/or a flow agent/thickener are disclosed for use in a vehicle occupant restraint system. The autoignition composition undergoes rapid autoignition at temperatures from approximately 190.degree. to 220.degree. C. thereby allowing the use of aluminum for the gas generator housing. The autoignition compositions of the present invention are safely manufactured by wet blending and may be installed via automation to the inte...
