Abstract

A cover for a cable harness including: (i) a first layer comprising a first color; (ii) a second layer layered adjacent to the first layer, the second layer comprising a second color that is different than the first color; and (iii) an adhesive layer adhered to the first layer, at least a portion of the adhesive is not covered by the second layer. The first color can black, while the second color is white. The second layer comprises fibers that can be substantially free of dye. At least one of the first layer and the second layer can be polyethylene terephthalate. The cover can cover a plurality of cables of a cable harness. If wear forms a hole through the first layer, the second color of the second layer is visible from an environment external to the covered cable harness through the hole through the first layer.

First claim

What is claimed is:

1. A cover for a cable harness comprising:
a first layer comprising a first color;
a second layer layered adjacent to the first layer, the second layer comprising a second color that is different than the first color; and
an adhesive layer adhered to the first layer, at least a portion of the adhesive layer is not covered by the second layer;
wherein, the first color is black, the second color is white, and the second color has CIELAB color space values within the following ranges: L*, 70 to 100; a*, −10 to 10; and b*, −10 to 10; and
wherein, the second layer comprises fibers that are substantially free of dye.

2. The cover of claim 1 , wherein
the first color has CIELAB color space values within the following ranges:
L*, 0 to 30;
a*, −10 to 10; and
b*, −10 to 10.

3. The cover of claim 1 , wherein
the second color, but not the first color, has CIELAB color space values within the following ranges:
L*, 70 to 100;
a*, −3 to 3; and
b*, −3 to 3.

4. The cover of claim 1 , wherein
the second color, but not the first color, has CIELAB color space values within the following ranges:
L*, 80 to 100;
a*, −4 to 4; and
b*, −4 to 4.

5. The cover of claim 1 , wherein
the second color, but not the first color, has CIELAB color space values within the following ranges:
L*, 90 to 100;
a*, −6 to 6; and
b*, −6 to 6.

6. The cover of claim 1 , wherein
at least one of the first layer and the second layer comprises polyethylene terephthalate.

7. The cover of claim 1 , wherein
at least one of the first layer and the second layer comprises a polyamide.

8. A covered cable harness comprising:
a plurality of cables; and
a cover covering at least a portion of the plurality of cables, the cover comprising:
a first layer comprising a first color, an outer surface facing away from the plurality of cables, and an inner surface facing toward the plurality of cables; and
a second layer layered adjacent to the first layer and facing the inner surface of the first layer, the second layer (i) disposed radially closer to the plurality of cables than the first layer and (ii) comprising a second color that is different than the first color;

wherein, the first color is black, the second color is white, and the second color has CIELAB color space values within the following ranges: L*, 70 to 100; a*, −10 to 10; and b*, −10 to 10; and
wherein, the second layer comprises fibers that are substantially free of dye.

9. The covered cable harness of claim 8 , wherein
the cover further comprises an adhesive adhered to the inner surface of the first layer; and
at least a portion of the adhesive is not covered by the second layer and is adhered to the inner surface of the first layer to at least partially secure the cover around the plurality of cables.

10. The covered cable harness of claim 8 , wherein
the first layer and the second layer are layered such that, upon formation of a hole through the first layer from abrasion,
the second color of the second layer is visible from an environment external to the covered cable harness through the hole through the first layer.

11. The covered cable harness of claim 8 , wherein
the first color has CIELAB color space values within the following ranges:
L*, 0 to 30;
a*, −10 to 10; and
b*, −10 to 10.

12. The covered cable harness of claim 8 , wherein
the second color, but not the first color, has CIELAB color space values within the following ranges:
L*, 80 to 100;
a*, −4 to 4; and
b*, −4 to 4.

13. The covered cable harness of claim 8 , wherein
the second color, but not the first color, has CIELAB color space values within the following ranges:
L*, 90 to 100;
a*, −6 to 6; and
b*, −6 to 6.

14. The covered cable harness of claim 8 , wherein
at least one of the first layer and the second layer comprise polyethylene terephthalate or a polyamide.
