1. Apparatus comprising:

  • an air bag/cover subassembly, andan inflator/reaction device subassembly which is adapted to be coupled to said air bag/cover subassembly to form an air bag module,said air bag/cover subassembly comprising a cover defining an air bag cavity in said cover and a folded air bag disposed within said air bag cavity, said cover having an access opening and a rim surrounding said access opening and said air bag having a gas inlet opening and a border portion surrounding said inlet opening, the border portion of said air bag being secured to the rim of said cover,said inflator/reaction device subassembly comprising an inflator housing having gas dispensing nozzles, means for producing gas disposed within said inflator housing, and a reaction device integral with and extending outwardly of said inflator housing,said reaction device being adapted to be coupled to said rim of said cover and the border portion of said air bag to couple said inflator/reaction device subassembly with said air bag/cover subassembly, andsaid inflator housing being adapted to be disposed with said gas dispensing nozzles in fluid communication with said gas inlet opening in said air bag when said inflator/reaction device subassembly is coupled with said air bag/cover subassembly;

    said apparatus further comprising a plurality of fasteners, said border portion of said air bag having a plurality of openings therein and said rim of said cover having corresponding openings therein, the openings in said border portion of said air bag adapted to be aligned with the openings in the rim of said cover, said fasteners extending through said aligned openings in said border portion of said air bag and said rim of said cover to connect said border portion of said air bag with said border rim of said cover,said reaction device having openings adapted to be aligned with at least some of the aligned openings in said rim of said cover and said border portion of said air bag to enable at least some of the fasteners connecting said rim of said cover with said border portion of said air bag to couple said inflator/reaction device subassembly with said air bag/cover subassembly;

    said rim of said cover having an inside surface presented to said air bag cavity and an outside surface forming part of the outside of said cover, said border portion of said air bag being disposed against said outside surface of said rim of said cover, said reaction device being adapted to be coupled to said rim with said border portion of said air bag captured between said reaction device and said outside surface of said rim.
