초록

A gas generating composition, particularly useful for inflating a vehicle occupant restraint, comprises an organic fuel, an oxidant, and iron oxide in an amount effective to provide a coolant function in the gas generating composition. At least a major portion of the iron oxide is substantially free of catalytic or paint grade material and has an average particle size in a narrow particle size distribution range greater than 100 microns.
