Selective non-catalytic reducing (SNCR) compounds, independent of the gas generant composition, reduce the toxicity of effluent gases produced by combustion of nonazide gas generating compositions used to inflate vehicle occupant restraint systems. It is believed that reaction of the NH2 radical (formed from the SNCR compound) with NO in the combustion gas forms N2 thereby decreasing the concentration of toxic nitrogen oxides therein. Heterogeneous placement of the reducing compound proximate to the gas generant bed within a gas generator ensures intima...
We claim: 1. A vehicle occupant restraint system comprising: an inflatable air bag; a gas generator for inflating said air bag; a nitrogen-containing gas generant composition within said gas generator that forms nitrogen oxide and/or nitrogen dioxide upon combustion thereof; and a selective non-catalytic reducing compound placed within said gas generator in heterogeneous relation to said gas generant composition, wherein said selective non-catalytic reducing compound is selected from the group consisting of ammonium salts and amine-containing compounds,...
