Abstract

The fastening arrangement is such that the gas generator can be fastened by means of a nut and bolt. The bolt is formed on the gas generator and extends through an opening of a holder component which can be fastened to a part of the vehicle to hold the air bag module. Electrical insulation (23) is arranged between the gas generator (15) and the holder part (17). The electrical insulation may be, for example, a body (23) of electrically insulating material extending at least over the contact region between the gas generator (15) and the holder part (17). This has an extension which engages through the opening of the holder part (17) and forms an insulation between the bolt (18) and the edge of the opening. A sleeve of electrically insulating material may also be provided between the nut (22) and the surface of the holder part (17) on which the nut is located.
