Abstract

A gas bag module for a vehicle occupant restraint device includes a rigid component (16). The rigid component (16) has a discharge opening (14) formed therein through which gas can escape. A control element (10) is arranged at the discharge opening (14). The control element (10) assumes a rolled-up state in the case of low pressure action and assumes an unrolled state in the case of greater pressure action.

Claims

1. A gas bag module for a vehicle occupant restraint device, the gas bag module including a rigid component having a discharge opening formed therein through which gas can escape, a control element being arranged at the discharge opening, the control element assuming a rolled-up state in the case of low pressure action and assuming an unrolled state in the case of greater pressure action.

2. The gas bag module according to claim 1, wherein the control element rolls up automatically through elastic force.

3. The gas bag module according to claim 1, wherein the control element comprises a tube-like body which unrolls through the blowing in of gas with a particular minimum pressure.

4. The gas bag module according to claim 3, wherein the tube-like body is arranged with one end at the edge of the discharge opening.

5. The gas bag module according to claim 1, wherein the control element is arranged next to the discharge opening so that in the unrolled state it provides at least for a partial covering of the discharge opening.
