Abstract

An attachment plate and towing lug combination for a vehicle having a crush can and a bumper beam includes a plate and a towing lug. The plate has a central portion and a flange portion. The towing lug is attached to the central portion of the plate and extends from an outer surface of the central portion of the plate. The flange portion of the plate is attachable to an end portion of the crush can. The central portion of the plate is attachable to a first side portion of the bumper beam. The towing lug extends to at least an outer surface of a second side portion of the bumper beam when the flange portion of the plate is attached to the end portion of the crush can and the central portion of the plate is attached to the first side portion of the bumper beam.

First claim

The invention claimed is:

1. An attachment for a vehicle, comprising:
a plate having a central portion including an outer surface and a flange portion;
a towing lug attached to the central portion of the plate and extending from the outer surface of the central portion of the plate;
a crush can having an end portion; and
a bumper beam having a first side portion and a second side portion including an outer surface;
wherein the flange portion of the plate is attachable to the end portion of the crush can;
wherein the central portion of the plate is attachable to the first side portion of the bumper beam; and
wherein the towing lug extends to at least the outer surface of the second side portion of the bumper beam when the flange portion of the plate is attached to the end portion of the crush can and the central portion of the plate is attached to the first side portion of the bumper beam;
wherein the bumper beam is made of a first fiber reinforced plastic composite material including a plurality of first fibers.

2. The attachment of claim 1 , wherein the bumper beam has a first end, a second end, and an axis; and
wherein each of the plurality of first fibers is aligned parallel to the axis of the bumper beam and extends from the first end to the second end of the bumper beam.

3. The attachment of claim 1 , wherein the crush can is made of a second fiber reinforced plastic composite material including a plurality of second fibers.

4. The attachment of claim 3 , wherein the crush can has a first end, a second end, and an axis; and
wherein each of the plurality of second fibers is aligned parallel to the axis of the crush can and extends from the first end to the second end of the crush can.

5. The attachment of claim 4 , wherein the bumper beam has a first end, a second end, and an axis; and
wherein each of the plurality of first fibers is aligned parallel to the axis of the bumper beam and extends from the first end to the second end of the bumper beam.

6. The attachment of claim 1 , wherein the bumper beam is configured with a passage; and
wherein the towing lug extends through the passage when the flange portion of the plate is attached to the end portion of the crush can and the central portion of the plate is attached to the first side portion of the bumper beam.

7. The attachment of claim 1 , wherein the end portion of the crush can has an outer surface;
wherein the flange portion of the plate has an inner flange surface;
wherein the inner flange surface of the flange portion of the plate is substantially normal to the outer surface of the central portion of the plate; and
wherein the inner flange surface of the flange portion of the plate is attachable to the outer surface of the end portion of the crush can.

8. The attachment of claim 1 , wherein the central portion of the plate is attachable to the first side portion of the bumper beam via a mechanical fastener.

9. The attachment of claim 8 , wherein the mechanical fastener is configured with an external thread;
wherein a nut configured with an internal thread is attached to the central portion of the plate; and
wherein the central portion of the plate is attachable to the first side portion of the bumper beam via engagement of the external thread of the mechanical fastener with the internal thread of the nut.

10. The attachment of claim 1 , wherein the central portion of the plate is attachable to the first side portion of the bumper beam via an adhesive.

11. The attachment of claim 1 , wherein the flange portion of the plate is attachable to the end portion of the crush can via an adhesive.

12. The attachment of claim 1 , wherein the flange portion of the plate is attachable to the end portion of the crush can via a mechanical fastener.

13. A vehicle, comprising:
a body structure, including:
a crush can having an end portion;
a bumper beam having a first side portion and a second side portion including an outer surface; and
an attachment plate and towing lug combination, including:
a plate having a central portion including an outer surface and a flange portion; and
a towing lug attached to the central portion of the plate and extending from the outer surface of the central portion of the plate;

wherein the flange portion of the plate is attached to the end portion of the crush can;
wherein the central portion of the plate is attached to the first side portion of the bumper beam; and
wherein the towing lug extends to at least the outer surface of the second side portion of the bumper beam;
wherein the bumper beam is made of a first fiber reinforced plastic composite material including a plurality of first fibers.

14. The vehicle of claim 13 , wherein the bumper beam has a first end, a second end, and an axis; and
wherein each of the plurality of first fibers is aligned parallel to the axis of the bumper beam and extends from the first end to the second end of the bumper beam.

15. The vehicle of claim 13 , wherein the crush can is made of a second fiber reinforced plastic composite material including a plurality of second fibers.

16. The vehicle of claim 15 , wherein the crush can has a first end, a second end, and an axis; and
wherein each of the plurality of second fibers is aligned parallel to the axis of the crush can and extends from the first end to the second end of the crush can.

17. The vehicle of claim 16 , wherein the bumper beam has a first end, a second end, and an axis; and
wherein each of the plurality of first fibers is aligned parallel to the axis of the bumper beam and extends from the first end to the second end of the bumper beam.

18. An attachment for a vehicle, comprising:
a plate having a central portion including an outer surface and a flange portion;
a towing lug attached to the central portion of the plate and extending from the outer surface of the central portion of the plate;
a crush can having an end portion; and
a bumper beam having a first side portion and a second side portion including an outer surface;
wherein the bumper beam is made of a first fiber reinforced plastic composite material;
wherein the crush can is made of a second fiber reinforced plastic composite material;
wherein the flange portion of the plate is attachable to the end portion of the crush can;
wherein the central portion of the plate is attachable to the first side portion of the bumper beam; and
