Abstract
Structure for generating nitrogen gas for inflating an air bag vehicle occupant resistant 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 30 to 50% by weight of an alkali metal azide, 40 to 60% by weight of sodium nitrate or potassium perchlorate, 5 to 15% by weight of boron, and 1 to 15% by weight of sodium silicate. The coating may also include 1 to 6% by weight of graphite fibers as a roughening agent.
