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 and outer cover and a light element positioned under the outer cover, wherein the light element is configured to emit light through at least a portion of the outer covering.

2. The steering wheel material of claim 1, wherein the covering material further comprises 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 outer cover includes at least one perforation to permit light from the light element to pass through the outer covering.

5. The steering wheel material of claim 1, wherein the outer cover includes a thinned area portion such that light from the light element is configured to transmit through the thinned area portion.

6. The steering wheel material of claim 1, wherein the covering material further includes a sealant material configured to seal a perforation in the outer cover, and wherein the sealant material is configured to permit light emitted from the light element to pass through the sealant material.

7. 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,

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

8. The steering wheel of claim 7, wherein the covering material further comprises a casing that is positioned under the outer cover.

9. The steering wheel of claim 7, further comprising a pluralitv of light elements arranged to light up separate sections of the steering wheel.

10. The steering wheel of claim 7, wherein the light element is configured to provide continuous back lighting of the steering wheel.

11. The steering wheel of claim 7, wherein the light element is configured to provide pulsed back lighting of the steering wheel.

12. The steering wheel of claim 7, wherein the light element is configured to provide non-continuous back lighting of the steering wheel.

13. The steering wheel of claim 7, wherein the outer covering includes at least one perforation to permit light from the light element to pass through the outer cover.

14. The steering wheel of claim 7, wherein the outer cover includes a thinned area portion such that light from the light element is configured to transmit through the thinned area portion.

15. The steering wheel of claim 7, wherein the covering material further includes a sealant material configured to seal a perforation in the outer cover, and wherein the sealant material is configured to permit light emitted from the light element to pass through the sealant material.
