  • Patent number: 5460668
    Abstract: Nonazide gas generating compositions are formed from a nonazide fuel, an oxidizer, and a heat absorbing additive in the form of a glass compound. The additive effects a reduction in the combustion temperature of the gas generant, thereby resulting in inflating gases having a reduced content of toxic gases such as NO.sub.x and CO. The gas generants are therefore nontoxic and useful for inflating a vehicle occupant restraint system.
