Nonazide gas generating compositions
First Claim
1. A gas generant composition useful for inflating an automotive air bag passive restraint system containing as a fuel at least one high nitrogen nonazide constituent selected from the group consisting of guanidine nitrate, aminoguanidine nitrate, nitroguanidine, nitroaminoguanidine, diaminoguanidine nitrate, guanidine perchlorate, and guanidine picrate, wherein:
- said fuel further consists of diammonium bitetrazole; and
said fuel is employed in a concentration of 5 to 85% by weight of the gas generant composition.

Abstract
Multicomponent pyrotechnic gas generating compositions are provided which comprise a single or multiple nonazide fuel. The single and multiple fuels are selected from guanidine, azole, and other high nitrogen aliphatic, aromatic, and/or heterocyclic compounds. The fuels are blended with single and multiple oxidizers. Other materials are added to the compositions for processing, aiding ignition, enhancing ballistics, reducing particulates, and scavenging undesirable gaseous decomposition products. A significant amount of nontoxic gas is formed at acceptable flame temperatures when these compositions are combusted, which allow their use in automotive air bag safety systems.
