Abstract
A wrapped gas generant cartridge is incorporated in an inflator of a vehicle occupant restraint system. The gas generant cartridge includes a stacked, aligned plurality of substantially flat annular wafers of gas generant material having a central opening therethrough. A wrap of sheet material surrounds the plurality of wafers and has marginal end panels folded along the end surfaces of the plurality of wafers, leaving at least one end opening exposed for receiving an ignition tube of the inflator. The wrap of sheet material is selected from metal foil, expanded metal, cellulose, thermoplastics, including polyolefin shrink wrap, with tape, adhesive or adhesive laminates holding the wrap in position. The gas generant cartridge is received in a filter and screen pack within the inflator.
