Abstract (en)

[origin: WO2009011769A1] Airbag inflators employ gas generating compositions formed from a mixture of fuels and a mixture of oxidizers and preferably mica at levels of 1 to 5 % by weight. The gas generant composition contains a primary and secondary fuel. The primary fuel is a guanidine compound, preferably guanidine nitrate. The secondary fuel is selected from tetrazoles, triazoles and mixtures thereof at levels of 5% by weight or less of the total gas generant composition. The oxidizer system is a mixture of at least two components selected from the group consisting of transition metal oxides, alkali metal nitrates and alkaline earth metal nitrates. The novel gas generants yield inflating gases having a reduced content of undesirable gases such as nitrous oxides and carbon monoxide.
