Abstract

The invention relates to a gas bag module comprising a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber. The gas bag further comprises an indentation running from the front wall section in an inflated state in a direction toward the rear wall section. The indentation is formed in that a part of the gas bag wall is prevented from an unimpeded movement towards outside of the module on unfolding of the gas bag. The gas bag, in a region of a mouth of the indentation, has a bubble-like inflatable extension in flow connection with the at least one chamber of the gas bag, which extension closes the indentation.
