Abstract
A heat-enhanced boosted inflator for a vehicle airbag includes a housing defining a storage chamber having compressed inflation gas therein and a heating cup mounted to the housing and defining a portion of a gas delivery path to the airbag. The heating cup contains a heat-producing material and the gas flows through the heat-producing material to heat-expand it. One heat-producing material is thermite (Al+FeO.sub.3) and ignitor means initiate its reaction. A cylindrical heating cup provides an annular heating chamber containing the heat-producing material and further defines an outlet plenum containing inflation gas which is released initially for a "soft" onset of inflation.
