Abstract: A gas bag module includes a module housing (18), a gas bag (24) having a gas bag wall (26), a discharge opening (20) which can be closed by a closure device (22), and a limiting strap (28), the limiting strap (28) being coupled with the gas bag wall (26) and the closure device (22). The limiting strap (28) is tensioned in case of an unimpeded unfolding of the gas bag (24) such that the closure device (22) closes the discharge opening (20), and the limiting strap (28) is guided along the gas bag wall (26).

Abstract: A gas bag for a vehicle occupant restraint arrangement includes an inner fabric layer (16), a middle fabric layer (20) and an outer fabric layer (18) lying one over another. Each fabric layer (16, 20, 18) has a section in which at least one opening (10, 14, 12) is formed. The overlapping of the sections with the openings (10, 14, 12) form a discharge opening of the gas bag. The section of the middle fabric layer (20) is movable relative to the sections of the inner and outer fabric layers (16, 18) depending on the internal pressure of the gas bag and thereby altering the cross section of the discharge opening.
