A subassembly () includes an inflator () for a vehicle safety system having a cylindrical outer wall (), at least one bolt () fastened to the outer wall () in a substance-to-substance or form-fit manner, for mounting the inflator () on a component and a saddle element () attached to the bolt. The saddle element () includes a supporting portion () that bears on the outer wall () of the inflator ().

Inflator fastening

For manufacturing a gas generator (), a tubular body () having an opening () in a circumferential wall () and a housing part () having an attachment end () are provided. The geometry of a proximate rim () of the opening () and that of the attachment end () are coordinated such that a first contact region encircling the opening () and a second contact region on the attachment end (), which is circumferentially closed, are formed. The housing part () is placed onto the tubular body () such that the first contact region is in contact with the second contact region. Then the body () and the housing part () are joined to each other by capacitor discharge welding.
