Abstract
The invention relates to a gas bag module comprising a gas bag, an outer contour of the gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant and a depression starting from the front wall. The depression is formed in that during inflation of the gas bag a center portion of the gas bag wall is prevented from freely moving and is restrained. The gas bag has around the depression a ring-shaped chamber to be filled with gas. At least one limiting strap is provided which engages the gas bag wall at a transition from the front wall to the depression, substantially extends alongside the depression and determines a depth of the depression.
