Abstract

A steering wheel comprises a rim connected to spokes. A covering material is provided to enclose at least a portion of the rim and/or the spokes. The covering material includes an outer cover and a light element positioned under the outer cover. The light element is configured to emit light through at least a portion of the outer cover. The light element is positioned over a casing that is provided to give shape to the steering wheel so that a vehicle driver may easily grasp the steering wheel. The light element may provide continuous, pulsed, or non-continuous lighting.

Claims

1. A steering wheel material, comprising:

a covering material, the covering material including;

an outer cover; and

a light element positioned under the outer cover, and

wherein the light element is configured to emit light through at least a portion of the outer cover,

wherein the outer cover includes at least one perforation to permit light from the light element to pass through the outer cover,

wherein the covering material further includes a sealant material configured to seal the at least one perforation in the outer cover.

2. The steering wheel material of claim 1, wherein the covering material further includes a casing that is positioned under the outer cover.

3. The steering wheel material of claim 1, further comprising a plurality of light elements.

4. The steering wheel material of claim 1, wherein the sealant material is configured to permit light emitted from the light element to pass through the sealant material.

5. The steering wheel material of claim 1, wherein the light element includes electroluminescent mylar.

6. The steering wheel material of claim 1, wherein the light element includes electroluminescent tubing.

7. The steering wheel material of claim 1, wherein the light element includes at least one light emitting diode.

8. The steering wheel material of claim 1, wherein the light element includes incandescent material or wires.

9. The steering wheel material of claim 1, wherein the light element includes fiber optic material.

10. The steering wheel material of claim 1, wherein the light element includes light emitting acrylic.

11. The steering wheel material of claim 1, wherein the sealant material fills the at least one perforation.

12. The steering wheel of claim 1, wherein the covering material further includes a layer comprising a temperature controlled substance.

13. The steering wheel of claim 1, wherein the covering material further includes an insulating layer.

14. A steering wheel, comprising:

a rim connected to spokes; and

a covering material enclosing at least a portion of the rim and/or spokes, the covering material including an outer cover and a light element positioned under the outer cover, and

wherein the light element is configured to emit light through at least a portion of the outer cover,

wherein the outer cover includes at least one perforation to permit light from the light element to pass through the outer cover,

wherein the covering material further includes a sealant material configured to seal the at least one perforation in the outer cover.

15. The steering wheel of claim 14, wherein the light element includes electroluminescent mylar.

16. The steering wheel of claim 14, wherein the light element includes electroluminescent tubing.

17. The steering wheel of claim 14, wherein the light element includes at least one light emitting diode.

18. The steering wheel of claim 14, wherein the light element includes incandescent material or wires.

19. The steering wheel of claim 14, wherein the light element includes fiber optic material.

20. The steering wheel of claim 14, wherein the light element includes light emitting acrylic.

21. The steering wheel of claim 14, wherein the sealant material is configured to permit light emitted from the light element to pass through the sealant material.
