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 is made of a gas generating material which includes 61-68% by weight of sodium azide, 0-5% by weight of sodium nitrate, 0-5% by weight of bentonite, 23-28% by weight of iron oxide, 1-2% by weight of fumed silica, and from about 2 to about 6% by weight of graphite fibers having a diameter of 3-15 microns and an average length of 40 to 125 thousandths of an inch.
