Igniter compositions for non-azide gas generants |
(57) In an inflator module for an automotive airbag which contains a gas generant, particularly
a non-azide gas generant, an igniter composition is provided for igniting the generant
such that the generant produces lower volumes of toxic gaseous combustion products.
The igniter composition has a fuel component which is 5 wt% to 100% Mg, TiH
2, Al or Ti, 0 to 95 wt% carbohydrate fuel having an oxygen content of 35 to 65 wt%;
and an oxidizer component which is potassium or sodium chlorate or potassium or sodium
perchlorate. The igniter composition has an oxygen-to-fuel ratio of at least 1 and
preferably at least 1.05.
