Abstract
A low temperature autoigniting composition for use in a mobile occupant restraint system comprising, a low temperature melting oxidizer and a fuel, wherein the low temperature autoigniting composition autoignites in the temperature range of about 130.degree. C. to about 175.degree. C. In a preferred embodiment, the composition comprises a low temperature melting oxidizer, a fuel, and a catalyst, wherein the composition autoignites in the temperature range of about 130.degree. C. to about 150.degree. C. Preferably, the oxidizer comprises about 20 to about 70 percent by weight of the composition, the fuel comprises about 10 to about 50 percent by weight of the composition, and the catalyst comprises about 2 to about 50 percent by weight of the composition. The autoignition propellants of the invention are designed to function at low temperatures and before heat damage to an airbag deployment mechanism can occur, for example, during a fire.
