ABSTRACT:
Structure for generating nitrogen gas for inflating an air bag vehicle occupant restraint comprises a grain made of an azide based material which generates gas upon combustion. The grain has an ignition enhancing coating thereon consisting essentially of 20 to 50% by weight of an alkali metal azide, 25 to 35% by weight of an inorganic oxidizer, 10 to 15% by weight of a fluoroelastomer binder, 15 to 25% by weight of magnesium, and 1 to 3% by weight of fumed silicon dioxide. The coating may also include 1 to 6% by weight of graphite as a roughening agent.
