ABSTRACT:
An inflator for inflating a vehicle occupant restraint is assembled by welding various components of the inflator together, inserting a canister of gas generating material into the inflator, and then welding a closure member to the other components of the inflator. The step of welding the closure member to the other components of the inflator is the only welding step which is performed after inserting the canister of gas generating material. Prior to insertion of the canister of gas generating material, an end wall and a flange of a combustion cup are positioned in abutting engagement with an end wall and a flange of a diffuser cup. The end walls and flanges of the combustion and diffuser cups are welded together. An initiator assembly for igniting the gas generating material in the canister is connected with the closure member. After the initiator assembly has been connected with the closure member, the closure member is positioned to block the open end of the combustion cup in which the canister of gas generating material is disposed.
