Abstract
Composition and process for inflating an automobile or aircraft occupant safety restraint bag which reduces the toxicity of the gases produced by gas generants. A relatively low energy nitrogen containing fuel is combined with a burn rate accelerator, such as an alkali metal salt, to form an azide-free gas generant composition which lowers the combustion temperature of the gas generants while also maintaining a rapid burn rate, thereby reducing toxicity of the resultant gases.

- 13. A method of reducing or eliminating toxic nitrogen oxides and carbon monoxide upon combustion of a gas generant composition, while still maintaining a relatively high burn rate during combustion comprising the step of combining a relatively low energy nitrogen containing fuel with a burn rate accelerator comprising an alkali metal salt of an organic acid.

21. An azide-free gas generating composition that forms gases on combustion useful for inflating a vehicle safety restraint device comprising at least one relatively low energy nitrogen containing fuel and at least one burn rate accelerator comprising alkali metal salts of organic acids, wherein said at least one relatively low energy nitrogen containing fuel reduces levels of toxic oxides of nitrogen and carbon monoxide upon combustion by reducing combustion temperatures for said azide-free gas generating composition, and wherein said at least one burn rate accelerator maintains a relatively high burn rate for said azide-free gas generating composition.
