Abstract

A gas bag module for a vehicle occupant restraint device includes a rigid component (10). The rigid component (10) has a discharge opening (12) formed therein through which gas can escape. A control arrangement through which gas can pass is provided at the discharge opening (12). The control arrangement is designed so that the quantity of the gas passing through depends on the speed of flow of the gas.

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 arrangement through which gas can pass being provided at the discharge opening, the control arrangement being designed so that the quantity of the gas passing through depends on the speed of flow of the gas.

2. The gas bag module according to claim 1, wherein the control arrangement comprises two plates lying opposite each other, a flow channel being formed between the plates, and at least one of the plates being mounted elastically.

3. The gas bag module according to claim 2, wherein the elastically mounted plate is mounted on at least one spring.

4. The gas bag module according to claim 2, wherein both plates are mounted elastically.

5. The gas bag module according to claim 1, wherein the control arrangement comprises a labyrinth-like flow channel.
