Abstract

An exemplary towing assembly includes, among other things, a bracket having laterally spaced channels, and a tow loop having laterally spaced arms. Each of the arms is configured to slide within a respective one of the channels from a deployed to a retracted position in response to a load applied to the tow loop. An exemplary method of positioning a tow loop includes, among other things, in response to a load applied to a tow loop, moving the tow loop from a deployed position to a retracted position within a bracket. The method further includes biasing the tow loop away from the retracted position toward a deployed position.

First claim

What is claimed is:

1. A towing assembly, comprising:
a bracket having laterally spaced channels; and
a tow loop having laterally spaced arms, each of the arms configured to slide within a respective one of the channels from a deployed to a retracted position in response to a load applied to the tow loop.

2. The towing assembly of claim 1 , wherein the tow loop is biased away from the retracted position toward the deployed position.

3. The towing assembly of claim 2 , further comprising a biasing structure configured to bias the tow loop away from the retracted position toward the deployed position.

4. The towing assembly of claim 3 , wherein the biasing structure comprises a protrusion that is received within a slot as the tow loop moves from the deployed to the retracted position.

5. The towing assembly of claim 3 , wherein the biasing structure comprises at least one ball bearing received within a slot on a wall of one of the channels as the tow loop moves from the deployed to the retracted position.

6. The towing assembly of claim 1 , further comprising at least one polymer-based shock absorber configured to bias the tow loop toward the deployed position.

7. The towing assembly of claim 6 , wherein the at least one polymer-based shock absorber includes a polymer-based shock absorber disposed within each of the channels.

8. The towing assembly of claim 3 , wherein the biasing structure comprises a tension slide clip received within a groove as one of the arms is moved from the deployed to the retracted position.

9. The towing assembly of claim 8 , wherein the groove is tapered such that the tension slide clip compresses as one of the arms is moved from the deployed to the retracted position.

10. The towing assembly of claim 1 , wherein the tow loop has a U-shape.

11. The towing assembly of claim 1 , further comprising a coupling arrangement that limits movement of the tow loop to prevent the arms from fully withdrawing from the channels such that the tow loop and the bracket remain coupled when towing a vehicle utilizing the tow loop.

12. The towing assembly of claim 11 , wherein the coupling arrangement comprises an extension of one of the tow loop or the bracket received within an aperture in the other of the tow loop or the bracket.

13. The towing assembly of claim 1 , wherein the tow loop is a U-bar, and further comprising a biasing structure associated with each of the arms of the U-bar, the biasing structure configured to bias the tow loop away from the retracted position toward the deployed position.

14. A method of positioning a tow loop, comprising:
in response to a load applied to a tow loop, moving the tow loop from a deployed position to a retracted position within a bracket;
biasing the tow loop away from the retracted position toward a deployed position, wherein the tow loop is a U-bar; and
biasing the tow loop away from the retracted position toward the deployed position using a biasing structure associated with each of the arms of the U-bar.

15. The method of claim 14 , further comprising slideably receiving a protrusion within a channel as the tow loop slides to the retracted position.

16. The method of claim 14 , further comprising biasing utilizing a polymer-based shock absorber.

17. The method of claim 16 , wherein the polymer-based shock absorber is disposed within channels that receive arms of the tow loop.

18. The method of claim 14 , further comprising biasing by deforming a slide clip as the tow loop moves to the retracted position.

19. The method of claim 14 , further comprising biasing using at least one ball bearing received within a slot on a wall of one of the channels as the tow loop moves from the deployed to the retracted position.
