Abstract
An apparatus (12) for inflating an inflatable vehicle occupant protection device (20) comprises a gas generating material (16) which when ignited produces gas to inflate the inflatable vehicle occupant protection device (20). The gas generating material (16) comprises a solid solution of a water soluble liquid oxidizer, a cross-linked hydrophilic gelling agent, and water. The cross-linked hydrophilic gelling agent comprises an effective amount of carbon atoms to provide a combustible mixture with the liquid oxidizer. The cross-linked hydrophilic gelling agent forms a reticulated structure in which the liquid oxidizer and water are immobilized.
