Abstract
An airbag system includes a cylindrical housing which defines a chamber for a gas generator. The ends of the housing are closed by plugs which are friction welded to the housing. One of the plugs carries an ignition device for a gas generator in the housing. Two arms extend from the housing, and the ends of the arms remote from the housing are provided with lugs for fixing an airbag cover to the housing. The arms, or the arms and the housing, define at least one groove for anchoring an airbag underneath the airbag cover and over part of the housing. This part of the housing is provided with a number of vent apertures which permit gas to flow from the housing into the airbag.
