Abstract

A bumper assembly includes a bumper beam, an extension, a crush can, and a bracket. The bumper beam extends longitudinally from a first end to a second end. The extension attaches to the first end of the bumper beam and has a segment parallel to the bumper beam and a leg extending transversely relative to the bumper beam. The crush can is attached to the segment. The bracket extends from the extension and is welded to the crush can.

First claim

What is claimed is:

1. A bumper assembly comprising:
a bumper beam extending longitudinally from a first end to a second end;
an extension attached to the first end of the bumper beam and having a segment parallel to the bumper beam and a leg extending transversely relative to the bumper beam;
a crush can attached to the segment; and
an external bracket attached to the leg and to the crush can, wherein the external bracket is V-shaped at an acute angle.

2. The bumper assembly of claim 1 , wherein the bumper beam has a vehicle-rearward face, and the crush can and the leg both extend from the vehicle-rearward face.

3. The bumper assembly of claim 1 , wherein the crush can is welded to the segment of the extension.

4. The bumper assembly of claim 1 , wherein the external bracket is welded to the leg of the extension and welded to the crush can.

5. The bumper assembly of claim 1 , further comprising:
a second extension attached to the second end of the bumper beam, the second extension having a second segment parallel to the bumper beam and a second leg extending transversely relative to the bumper beam;
a second crush can attached to the second segment of the second extension; and
a second external bracket attached to the second leg of the second extension and to the second crush can.

6. The bumper assembly of claim 1 , wherein the extension includes a cantilevered end spaced from the bumper beam.

7. The bumper assembly of claim 1 , wherein the extension includes an inner extension and an outer extension extending coaxially from the first end of the bumper beam, the inner extension defining at least a portion of the leg and at least a portion of the segment, the crush can and the external bracket being attached to the inner extension.

8. The bumper assembly of claim 7 , wherein the crush can is welded to the segment of the extension, the external bracket is welded to the leg of the extension and welded to the crush can, and the extension includes a cantilevered end.

9. A bumper assembly comprising:
a bumper beam extending longitudinally from a first end to a second end;
an extension attached to the first end and having a segment parallel to the bumper beam and a leg extending transversely relative to the bumper beam, the segment having a slot extending from a front face to a rear face of the segment; and
a crush can extending from the rear face; and
a flange fixed to the crush can and welded to the segment at the slot, wherein the flange extends along the rear face across the slot.

10. The bumper assembly of claim 9 , wherein the crush can includes a wall defining a cavity elongated in a direction transverse to the bumper beam, wherein the flange extends from the wall into the cavity.

11. The bumper assembly of claim 9 , wherein the bumper beam has a vehicle-rearward face, and the crush can and the leg both extend from the vehicle-rearward face.

12. The bumper assembly of claim 9 , wherein the extension includes an inner extension and an outer extension extending coaxially from the first end of the bumper beam, the inner extension defining at least a portion of the leg and the segment, the crush can and the flange being attached to the inner extension.

13. The bumper assembly of claim 9 , wherein the crush can is welded to the segment of the extension.

14. The bumper assembly of claim 9 , wherein the extension includes a cantilevered end spaced from the bumper beam.

15. A bumper assembly comprising:
a bumper beam extending longitudinally from a first end to a second end;
an extension attached to the first end of the bumper beam and having a segment parallel to the bumper beam and a leg extending transversely relative to the bumper beam;
a crush can attached to the segment; and
a bracket fixed to the crush can and welded to the extension, wherein the bracket is V-shaped at an acute angle.

16. The bumper assembly of claim 15 , wherein the bracket is welded to the leg of the extension and is welded to the crush can.

17. The bumper assembly of claim 15 , wherein the crush can is welded to the segment of the extension.

18. The bumper assembly of claim 15 , wherein the segment has a slot and the bracket is welded to the segment at the slot.

19. The bumper assembly of claim 18 , wherein the crush can includes a wall defining a cavity elongated in a direction transverse to the bumper beam, wherein the flange extends from the wall into the cavity.

20. The bumper assembly of claim 19 , wherein the extension includes an inner extension and an outer extension extending coaxially from the first end of the bumper beam, the inner extension defining at least a portion of the leg and at least a portion of the segment, the slot being defined in the inner extension between the crush can and the outer extension.
