Abstract

A gas bag module includes a gas bag, a gas generator, a first and a second fastening element, a section of the gas bag being fastened between the first and the second fastening elements, and a discharge opening for diverting gas generated by the gas generator and introduced into the gas bag. The discharge opening can be brought from a closed state into an opened state and comprises at least one opening in the first and in the second fastening elements. A section of the gas bag extends over the discharge opening in the closed state and the gas bag is exposed towards an interior of the gas bag in a region of the discharge opening. Means are provided which partially destroy the gas bag in the region of the discharge opening, in order to uncover the discharge opening.
