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 an indentation starting from the front wall. The indentation is formed in that a center portion of the gas bag wall is prevented from freely moving during inflation and is restrained. The gas bag has a ring-shaped chamber to be filled with gas and extends around the indentation. Arranged in the indentation is at least one limiting strap which extends along the indentation and has an end pointing out of the indentation and, related to an inflated condition of the gas bag, is attached to the gas bag wall at least at the end pointing out of the indentation.
