Abstract
The invention relates to a gas bag restraining device comprising a gas bag module which has a gas bag with a front wall upon which an occupant to be restrained can impact in a case of restraint. The front wall has a depression which is produced in that a center portion of the front wall is attached to the module and is prevented from moving when the gas bag is inflated. The gas bag restraining device further comprises a module cover closing a ring-shaped outlet opening of the gas bag module. The module cover has a central hole which is covered by a cap which is stationary during opening of said gas bag module. The module cover has an edge defining the central hole and opens, preferably tears, towards outside starting from the edge. A holding connection is provided between the edge and the cap which is released when said gas bag module is opened.
