Abstract

A housing for an airbag module includes an extrusion incorporating a body portion and a cover extruded integrally with the body portion so as to form a single monolithic unit. At least one endcap formed separately from the extrusion is operatively coupled to an end of the extrusion so as to seal the end.

Claims

1. A housing for an airbag module, the housing comprising:

an extrusion incorporating a body portion and a cover extruded integrally with the body portion so as to form a single monolithic unit;

at least one endcap formed separately from the extrusion and operatively coupled to an end of the extrusion so as to seal the end, said at least one endcap disengaged from said extrusion upon activation of the airbag module; and

an endcap positioning control means operatively coupled to the housing so as to restrict a movement of the at least one endcap after activation of the airbag module.

2. The housing of claim 1 wherein the cover comprises a flexible first portion connected to a first edge of the body portion, and a flexible second portion connected to a second edge of the body portion opposite the first edge.

3. The housing of claim 2 further comprising disengageable connecting means structured to connect the first portion and the second portion along a seam formed therebetween.

4. The housing of claim 3 wherein the disengageable connecting means comprises a hook and loop fastening system.

5. The housing of claim 3 wherein the disengageable connecting means comprises an adhesive material.

6. The housing of claim 3 wherein the disengageable connecting means comprises a clasping mechanism extruded integrally with the remainder of the extrusion, the clasping means being formed along an edge of at least one of the first portion and the second portion, the clasping mechanism being structured to engage a portion of the other one of the first portion and the second portion to form a connection therebetween.

7. The housing of claim 1 wherein the extrusion is formed with a relatively sharp exterior corner extending along a length thereof, in a direction parallel to an axis of extrusion.

8. The housing of claim 1 further comprising a first opening and a second opening formed in at least one end of the extrusion, and wherein a first portion of the at least one endcap extends into the first opening and a second portion of the at least one endcap extends into the second opening, to secure the at least one endcap to the extrusion.

9. The housing of claim 1 wherein the endcap includes a mounting flange formed integrally with a body portion of the endcap and extending from the body in a direction away from the extrusion.

10. The housing of claim 1 wherein the extrusion is formed from Adflex KSO21P Polyolefin.

11. An airbag module including a housing in accordance with claim 1.

12. A vehicle occupant protection system including an airbag module in accordance with claim 11.

13. A vehicle including an airbag module in accordance with claim 11.

14. The airbag module of claim 1 wherein an opening is formed in the endcap, and wherein the endcap positioning control means comprises a tether having a first end operatively coupled to an interior of the housing, the tether extending from the housing interior through the endcap opening to an exterior of the housing.
