ABSTRACT:
A vehicle occupant restraint assembly (12) has an inflatable vehicle occupant restraint (20), a housing (14), a gas generating material (16) within the housing, an igniter (18) for igniting the gas generating material, and gas flow channel (22) for directing the gas which is generated into the vehicle occupant restraint. The vehicle occupant restraint is preferably an air bag. The gas generating material (16) contains (a) an alkali metal azide, alkaline earth metal azide or aluminum azide and (b) a metal oxidant which is the gamma form of ferric oxide (Fe.sub.2 O.sub.3). The metal oxidant is present in the gas generating composition in an approximately stoichiometric amount with regard to the metal azide, or in an amount slightly in excess of stoichiometric.
