Gas bag restraining device

A gas bag restraining device comprising:

• a gas bag module having a gas bag with a front wall for restraining an occupant, said front wall having a depression defined by a center portion of said front wall attached to said gas bag module, said center portion of said front wall being prevented from moving when said gas bag is inflated;
• a module cover for closing a ring-shaped outlet opening of said gas bag module, said module cover having a central hole covered by a stationary cap and an edge defining said central hole;
• and
• a holding connection provided between said edge and said stationary cap, said holding connection being released when said gas bag module is opened so that said module cover opens outwardly starting from said edge,
• said edge extending obliquely from an underside of said module cover toward an underside of said cap, said edge defining a chamfer extending along an outer perimeter of said cap.
