Abstract

A vehicle display assembly includes a light source and a flexible light guide configured to emit light therefrom. The assembly may include a steering wheel assembly to which the flexible light guide is operably coupled. The vehicle display assembly may be configured to emit light in at least first, second, and third colors. For example, the vehicle display assembly may be configured to illuminate the flexible light guide in the first color in a first mode, in the second color in a second mode, and in the third color in a third mode.

Claims (26)

1. A vehicle display assembly, comprising:

a steering wheel comprising a hub, a rim and a spoke coupled between the hub and the rim;

at least one light source in the spoke; and

at least one flexible light guide attached between the hub and the rim and disposed within a space between the hub, the rim and the spoke, the light guide configured to emit light from the at least one light source therefrom.

2. The vehicle display assembly of claim 1 , the spoke has a curved surface, a portion of the flexible light guide being positioned along the curved surface of the spoke.

3. The vehicle display assembly of claim 2 , wherein the at least one light source is configured to illuminate the flexible light guide in a plurality of different colors.

4. The vehicle display assembly of claim 3 , wherein the vehicle display assembly is configured to illuminate the flexible light guide in a first color of the plurality of different colors in a first mode, and the vehicle display assembly is configured to illuminate the flexible light guide in a second color of the plurality of different colors in a second mode.

5. The vehicle display assembly of claim 4 , wherein the at least one flexible light guide is comprised of silicon.

6. The vehicle display assembly of claim 5 , wherein the at least one light source comprises a light emitting diode.

7. The vehicle display assembly of claim 6 , wherein the at least one light source comprises a RGB light emitting diode package configured in to light the flexible light guide in the plurality of different colors.

8. The vehicle display assembly of claim 7 , wherein the at least one light source comprises a plurality of light emitting diodes.

9. The vehicle display assembly of claim 8 , wherein the at least one flexible light guide is press fit to the spoke.

10. The vehicle display assembly of claim 9 , the vehicle display assembly being configured to illuminate the flexible light guide in a third color of the plurality of different colors in a third mode.

11. The vehicle display assembly of claim 4 , wherein the flexible light guide is an optical fiber conductor.

12. A vehicle display assembly for a vehicle having a steering wheel with a spoke extending between a hub and a rim, the display assembly, comprising:

at least one light source integrated into the spoke; and

at least one flexible light guide disposed within a space between the hub, Rim and spoke, the flexible light guide configured to be illuminated by the light source in at least first, second, and third colors, the light guide configured to emit light from the at least one light source therefrom,

wherein the vehicle display assembly is configured to illuminate the flexible light guide in the first color in a first mode, the vehicle display assembly being configured to illuminate the flexible light guide in the second color in a second mode, and the vehicle display assembly being configured to illuminate the flexible light guide in the third color in a third mode.

13. The vehicle display assembly of claim 12 , the flexible light guide being positioned along a curved rigid surface of the spoke.

14. The vehicle display assembly of claim 13 , wherein the at least one flexible light guide is comprised of silicon.

15. The vehicle display assembly of claim 14 , wherein the at least one light source comprises a light emitting diode.

16. The vehicle display assembly of claim 15 , wherein the at least one light source comprises a RGB light emitting diode package configured in to light the flexible light guide in the plurality of different colors.

17. The vehicle display assembly of claim 16 , wherein the at least one light source comprises a plurality of light emitting diodes.

18. The vehicle display assembly of claim 13 , wherein the flexible light guide is an optical fiber conductor.

19. The vehicle display as recited in claim 1 , including at least one side housing mounted to the rim, the at least one side housing supporting the at least one light source and the at least one flexible light guide includes a portion disposed adjacent the at least one side housing.

20. The vehicle display as recited in claim 19 , wherein the at least one flexible light guide comprises a planar shape with at least one side curved to correspond to a contour of the steering wheel.
