Abstract: A gas bag module comprises a gas bag which has a front wall for the impact of an occupant. The gas bag is formed by a gas bag wall of several fabric parts. At least one of the fabric parts forms the front wall having an opening from which, in an inflated state of the gas bag, a depression originates, which is formed in that a center section of the gas bag wall on inflation is prevented from a free movement and is held back. The gas bag has around the depression an annular chamber which is to be filled. The opening is constructed in a slit shape.
