An autoignition composition for the gas generator of a vehicle occupant restraint system that is thermally stable at temperatures up to 110.degree. C., autoignites between 150.degree. C. and 175.degree. C., produces minimal toxic gases upon combustion, provides for a reduced gas inflator size, and can be safely produced using simple processing methods. By mixing an alkali metal nitrite with a nitrogen-based fuel, the resulting gas generants autoignite at or below 175.degree. C. The addition of an alkaline earth metal nitrite or nitrate provides the stabi...
[ We claim:] [1.] A gas generant composition consisting essentially of a mixture of:about 1% to 30% of a first oxidizer selected from the group consisting of alkali metal nitrites;about 0% to 20% of an inert component selected from the group consisting of clay, diatomaceous earth, talc, silica, and alumina;about 28% to 40% of a fuel component(s) selected from the group consisting of 1H-tetrazole, 5-aminotetrazole, 5-nitrotetrazole, 5-nitroaminotetrazole, 5,5'-bitetrazole, diguanidinium-5,5'-azotetrazolate, 3-nitro-1,2,4-triazole, 3-nitro-1,2,4-triazole-5...
