  • Multiple layered gas generating disk for use in gas generators
    Patent number: 5507890
    Abstract: 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.
