Housing for an airbag module and method for manufacturing such housing

1. A housing for an airbag module for accommodating a folded gas bag, comprising a base portion and at least one lateral portion projecting from the base portion, wherein at least one of the portions comprises at least two layers of a flexible material, wherein the at least two layers are superimposed and are cohesively connected with each other, wherein between the at least two layers a connecting material is provided to connect the at least two layers, wherein the connecting material has a two-dimensional extension over the entire surface of the at least two layers, between the at least two layers, and wherein the connecting material is activatable by application of pressure and/or temperature, so that the connecting material connects the at least two layers, wherein the flexible material comprises a fabric.

2. The housing according to claim 1 , wherein the connecting material, before it connects the at least two layers with each other, is formed as layer to be arranged separately between the at least two layers or as coating of at least one of the at least two layers.

3. The housing according to claim 1 , wherein the connecting material has a lower melting point than the flexible material.

4. The housing according to claim 1 , wherein the connecting material comprises a thermoplastic material.

5. The housing according to claim 4 , wherein the connecting material comprises a thermoplastic polyurethane.

6. The housing according to claim 1 , wherein each portion comprises at least two layers.

7. A method for manufacturing the housing of claim 1 , comprising the following steps:

arranging the at least two layers one above the other such that the at least two layers are superimposed,

cohesively connecting the at least two layers with each other by placing the connecting material between the at least two layers, and

applying pressure and/or temperature to activate the connecting material.

8. The method according to claim 7 , before cohesively connecting the at least two layers, the same are arranged with respect to a shape-giving device.

9. The method according to claim 8 , wherein before cohesively connecting the at least two layers together with a folded gas bag, the same are arranged in the shape-giving device.

10. The method according to claim 8 , wherein before cohesively connecting the at least two layers, the same are releasably attached to the shape-giving device.

11. The method according to claim 7 , wherein before cohesively connecting the at least two layers, the connecting material in the form of a foil is positioned between the at least two layers.
