Abstract

A cable includes a core with a plurality of first wires made of carbon steel and a plurality of strands surrounding the core. Each strand includes a plurality of second wires made of stainless steel. The cable has a maximum cross-sectional dimension less than 2 millimeters.

First claim

What is claimed is:

1. A cable comprising:
a core including a plurality of first wires made of carbon steel; and
a plurality of strands surrounding the core, each strand including a plurality of second wires made of stainless steel,
wherein the cable has a maximum cross-sectional dimension less than 2 millimeters, and
wherein the cable has a breaking strength of at least 2000 Newtons.

2. The cable of claim 1 , wherein the cable has a corrosion resistance under ASTM B117 greater than 312 hours.

3. The cable of claim 1 , wherein the cable has a corrosion resistance under ASTM B117 between 600 hours and 1,000 hours.

4. The cable of claim 1 , wherein the plurality of first wires includes nineteen first wires.

5. The cable of claim 1 , wherein the plurality of second wires includes seven second wires.

6. The cable of claim 1 , wherein each of first wire of the plurality of first wires includes a zinc and nickel coating, and wherein each wire of the plurality of second wires is uncoated.

7. The cable of claim 6 , wherein the core includes a plastic moisture barrier surrounding each first wire of the plurality of first wires.

8. The cable of claim 1 , wherein the plurality of strands includes eight strands.

9. The cable of claim 1 , wherein the cable elastically elongates less than 1% of its total length and plastically elongates less than 0.05% of its total length under a tensile load of about 60% of a breaking strength of the cable.

10. The cable of claim 1 , wherein the breaking strength is at least 2,500 Newtons.

11. A cable comprising:
a core including a plurality of first wires; and
a plurality of strands surrounding the core, each strand including a plurality of second wires,
wherein the plurality of first wires includes nineteen first wires, wherein the plurality of second wires includes seven second wires, and wherein the plurality of strands includes eight strands,
wherein the cable defines a maximum cross-sectional dimension less than 2 millimeters,
wherein the cable has a breaking strength of at least 2000 Newtons,
wherein the cable elastically elongates less than 1% of its total length and plastically elongates less than 0.05% of its total length under a tensile load of about 60% of the breaking strength, and
wherein the cable has a corrosion resistance under ASTM B117 greater than 312 hours.

12. The cable of claim 11 , wherein the cable has a corrosion resistance under ASTM B117 between 600 hours and 1,000 hours.

13. The cable of claim 11 , wherein each first wire of the plurality of first wires is made of carbon steel with a zinc and nickel coating, and wherein each second wire of the plurality of second wires is made of uncoated stainless steel.

14. The cable of claim 11 , wherein the core includes a plastic moisture barrier.

15. The cable of claim 11 , wherein the maximum cross-sectional dimension of the cable is about 1.5 millimeters.

16. A window regulator system comprising:
a track;
a carriage coupled to the track for movement along the track;
a window coupled to the carriage for movement with the carriage along the track;
a cable coupled to the carriage, the cable including
a core having a plurality of first wires made of carbon steel, and
a plurality of strands surrounding the core, each strand having a plurality of second wires made of stainless steel; and
a motor coupled to the cable and operable to move the carriage along the track via the cable,

wherein the cable has a maximum cross-sectional dimension less than 2 millimeters, and
wherein the cable has a breaking strength of at least 2000 Newtons.

17. The window regulator system of claim 16 , wherein the cable has a corrosion resistance under ASTM B117 greater than 312 hours.

18. The window regulator system of claim 16 ,
wherein the plurality of first wires includes nineteen first wires,
wherein the plurality of second wires includes seven second wires,
wherein the plurality of strands includes eight strands, and
wherein each second wire of the plurality of second wires is uncoated.

19. The window regulator system of claim 18 , wherein the core includes a plastic moisture barrier.

20. The window regulator system of claim 16 , wherein the breaking strength is at least 2,500 Newtons.
