Abstract

A side underride system configured to be coupled to a trailer may comprise a first skirt wall coupled to the trailer, positioned below a first side wall of the trailer, and extending along a first length of the trailer between a skirt wall front end and a skirt wall rear end and a cable system including a first cable coupled to the trailer, positioned below the first side wall, and extending along a second length of the trailer between a cable system front end and a cable system rear end, the skirt wall rear end being positioned forward of the cable system rear end.

First claim

We claim:

1. A side underride system configured to be coupled to a trailer, comprising:
a first skirt wall coupled to the trailer, positioned below a first side wall of the trailer, and extending along a first length of the trailer between a skirt wall front end and a skirt wall rear end; and
a cable system including a first cable coupled to the trailer, positioned below the first side wall, and extending along a second length of the trailer between a cable system front end and a cable system rear end, the skirt wall rear end being positioned forward of the cable system rear end.

2. The side underride system of claim 1 , wherein the first length of the skirt wall extends from an area near landing gear of the trailer to an area forward of a rear wheel assembly of the trailer, and the second length of the cable system extends from an area forward of the rear wheel assembly of the trailer to a point rearward of the rear wheel assembly.

3. The side underride guard of claim 1 , wherein the skirt wall further includes a cable separate from the cable system and extending along at least a portion of the skirt wall.

4. The side underride system of claim 1 , wherein the skirt wall includes:
a planar material extending along at least a portion of the first length; and
one or more horizontal cables coupled to and extending along at least a portion of the planar material.

5. The side underride system of claim 1 , wherein the skirt wall is formed of a substantially flexible material.

6. The side underride system of claim 1 , wherein the first and second lengths do not overlap.

7. The side underride system of claim 1 , wherein the skirt wall is coupled directly to a cross-member of a floor assembly of the trailer.

8. The side underride guard of claim 4 , further including a mounting bracket coupled to the trailer near a rear end of the skirt wall, wherein both the skirt wall rear end and the cable system front end are coupled to the mounting bracket, and wherein the one or more horizontal cables is routed through an aperture in the mounting bracket.

9. The side underride guard of claim 1 further including at least one diagonal truss beam coupled to the skirt wall.

10. A side underride system configured to be coupled to a trailer, comprising:
a skirt assembly including (i) a first skirt wall coupled to the trailer, positioned below a first side wall of the trailer, and extending between a front of the trailer and a location forward of a rear wheel assembly of the trailer, and (ii) a first cable coupled to the first skirt wall; and
a cable system including a second cable coupled to the trailer, positioned below the first side wall, and extending from a second location forward of the rear wheel assembly of the trailer to a location rearward of the rear assembly.

11. The side underride system of claim 10 , wherein the skirt wall is formed of a flexible material.

12. The side underride system of claim 10 , further including a mounting bracket coupled to the trailer, a rear end of the first cable and a forward end of the second cable being coupled to the mounting bracket.

13. The side underride system of claim 10 , wherein the second cable is removably coupled to the trailer such that the rear wheel assembly of the trailer may be accessed upon removal of the second cable.

14. The side underride system of claim 10 , wherein the first cable has a first longitudinal length along a length of the trailer, the second cable has a second longitudinal length along the length of the trailer, and the first and second longitudinal lengths do not overlap.

15. The side underride guard of claim 10 , wherein a first end of the second cable is coupled to a mounting bracket forward of the rear wheel assembly and a second end of the second cable is coupled to a rear impact guard positioned rearward of the rear wheel assembly such that the second cable extends over the rear wheel assembly.

16. A side underride system configured to be coupled to a trailer, comprising:
a cable system including
(i) a first cable having a first terminal end configured to be coupled to a first side of the trailer forward of a rear wheel assembly of the trailer and a second terminal end configured to be coupled to the trailer rearward of the rear wheel assembly of the trailer and
(ii) a second cable having a first terminal end configured to be coupled to a second side of the trailer forward of the rear wheel assembly of the trailer and a second terminal end configured to be coupled to the trailer rearward of the rear wheel assembly of the trailer, the first and second cables extending past the rear wheel assembly inhibiting movement of objects into an area around the rear wheel assembly without material coupled to portions of the first and second cables adjacent the rear wheel assembly.

17. The side underride system of claim 16 , wherein the second ends of the first and second cables are configured to be attached to and terminate at a rear impact guard of the trailer.

18. The side underride system of claim 16 , wherein the first ends of the first and second cables are configured to be attached to and terminate at a mounting bracket coupled to the trailer or an aerodynamic skirt coupled to the trailer.

19. The side underride system of claim 16 , wherein the first and second cables are configured to be selectively attached to and detached from the trailer.

20. The side underride system of claim 16 , wherein the first and second cables are sized to extend a distance less than half of a length of the trailer to which the first and second cables are attached.
