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.

Iron oxide as a coolant and residue former in an organic propellant

The present invention resides in a body of material which is ignitable to generate a gas for inflating an air bag. The body of material comprises at least two layers of ignitable gas generating material which are pressed together. One of the layers comprises a nitrogen generating composition which is easily ignited and burns rapidly. The other of the layers comprises a nitrogen generating composition which is less easily ignited and burns less rapidly than the one layer.

Multiple layered gas generating disk for use in gas generators

A filter filters the gas generated by an air bag inflator. The gas comprises an alkali metal oxide. The inflator comprises a non-woven metal fibrous mat and small particles of a silicon compound, reactive with the alkali metal oxide, adhered to strands of the mat.
