Abstract

The invention relates to a gas bag module comprising a gas bag with a gas bag wall which has a front and a rear wall section. A depression is provided which has a mouth and runs in an inflated state of the gas bag from the front wall section to the rear wall section, which depression is formed in that a part of the gas bag wall is prevented from an unimpeded movement away from the module on unfolding of the gas bag. The module further comprises at least one closure piece which is fastened to the gas bag wall such that in the inflated state it moves in front of the mouth of the depression and closes the depression.
