Auto ignition in gas generator.

摘要

An enclosure (52), adapted to hold an auto ignition material (54) in a gas generator that employs solid fuel gas generant material to effect inflation of a protective bag to cushion a passenger from impact with the structure of a vehicle in the event of a crash, is provided. The enclosure comprises a retention cup (56) adapted to be press fitted into a recess in a gas generator body and retained by deformation of integral circumferentially spaced ribs (66). The auto ignition material is retained by a retention screen (58) of wire mesh or the like, held in place by an inwardly bent flange (88).
