Abstract
The invention relates to a gas bag restraint device including a gas bag module which has a gas bag wall. The gas bag wall has a front wall upon which an occupant to be restrained can impact in a case of restraint and has a depression defined by a ring-shaped gas bag wall portion. The depression is generated in that a center portion of the front wall is attached to the module and is prevented from movement when the gas bag is inflated. A holder is provided at the ring-shaped gas bag wall portion that keep parts of the ring-shaped gas bag wall portion, which get in contact with each other when the gas bag is inflated, in contact with each other in a fully inflated condition of the gas bag, and at least partly close the depression.
