Abstract

An instrument panel assembly for a passenger compartment is provided, including an instrument panel surface, a light emitter that emits a light beam so that the light beam extends along a beam path, and a light receiver that senses the light beam and detects a desired instrument setting change.

Claims

1. A switch assembly for an instrument panel assembly in a vehicle a passenger compartment comprising:

an instrument panel having a surface generally defining a plane;

a light emitter supported by the instrument panel and configured to emit a light beam along a beam path that extends in a direction generally parallel with the plane; and

a light receiver supported by the instrument panel and configured to sense the light beam; and

a controller coupled to the light receiver and configured to detect interruptions in the light beam sensed by the light receiver indicative of a desired instrument setting change of the instrument panel.

2. A switch assembly for an instrument panel assembly as in claim 1, further comprising at least one deflector positioned along the beam path to separate the beam path into first and second portions, wherein the second portion of the beam extends in the direction generally parallel with the plane.

3. A switch assembly for an instrument panel assembly as in claim 2, wherein the first portion of the beam path extends through the instrument panel surface.

4. A switch assembly for an instrument panel assembly as in claim 2, wherein the second portion of the beam path is located on a side of the surface toward the passenger compartment.

5. A switch assembly for an instrument panel assembly as in claim 1, wherein a portion of the beam path is located on a side of the surface toward the passenger compartment.

6. A switch assembly for an instrument panel assembly as in claim 1, wherein a portion of the beam path is located on a side of the surface away from the passenger compartment.

7. A switch assembly for an instrument panel assembly as in claim 1, further comprising an adjustment member mounted to the surface and being movable to selectively obstruct the beam path.

8. A switch assembly for an instrument panel assembly as in claim 7, wherein the adjustment member includes a protrusion extending therefrom and being moveable to obstruct the beam path.

9. A switch assembly for an instrument panel assembly as in claim 1, wherein the light emitter is a light emitting diode.

10. A switch assembly for an instrument panel assembly as in claim 1, wherein the light beam is an infrared beam.

11. A switch assembly for an instrument panel assembly in a vehicle passenger compartment comprising:

a base panel configured to support at least one instrument display component;

a protective panel defining a plane and spaced apart from the base panel by a gap distance;

a light emitter supported by the instrument panel and configured to emit a light beam along a beam path so that at least a portion of the beam path extends at an angle substantially less than 90 degrees with respect to the plane;

a light receiver supported by the instrument panel and configured to sense the light beam; and

a controller coupled to the light receiver and configured to detect interruptions in the light beam sensed by the light receiver indicative of a desired instrument setting change of the instrument panel.

12. A switch assembly for an instrument panel assembly as in claim 11, wherein the angle is substantially less than 45 degrees.

13. A switch assembly for an instrument panel assembly as in claim 12, wherein the angle is generally equal to 0 degrees.

14. A switch assembly for an instrument panel assembly as in claim 11, wherein the light emitter and the light receiver are supported by the base panel.

15. A switch assembly for an instrument panel assembly as in claim 14, further comprising first and second deflectors supported by the protective panel and configured to deflect the light beam so that a first portion of the beam path extends between the light emitter and the first deflector, a second portion of the beam path extends between the first deflector and the second deflector, and a third portion of the beam path extends between the second deflector and the light receiver.

16. A switch assembly for an instrument panel assembly as in claim 15, wherein the first portion and the third portion of the beam path each extend through the protective panel.

17. A switch assembly for an instrument panel assembly as in claim 15, wherein the second portion of the beam path is located on a side of the surface toward the passenger compartment.

18. A switch assembly for an instrument panel assembly as in claim 15, further comprising:

a third deflector supported by the protective panel and cooperating with the first deflector to separate the light beam into a first light beam extending along the beam path and a second light beam extending along a second beam path;

a fourth deflector supported by the protective panel and cooperating with the third deflector to define the second beam path; and

a second light receiver supported by the base panel and configured to sense the light beam of the second beam path to detect a second desired instrument setting change.

19. A switch assembly for an instrument panel assembly as in claim 11, further comprising an adjustment member mounted to the protective panel and being moveable to selectively obstruct the beam path.

20. A switch assembly for an instrument panel assembly as in claim 19, wherein the light emitter and the light receiver are aligned with each other so that the beam path is generally linear.

21. A switch assembly for an instrument panel assembly as in claim 19, wherein the adjustment member is a rotatable knob.

22. A switch assembly for an instrument panel assembly as in claim 19, further comprising a second light emitter and a second light receiver.

23. A switch assembly for an instrument panel assembly as in claim 22, further comprising a third light emitter, a third light receiver, a fourth light emitter, and a fourth light receiver.

24. A switch assembly for an instrument panel assembly as in claim 19, further comprising a side panel extending between the base panel and the protective panel, wherein the light emitter and the light receiver are each connected to the side panel.

25. A switch assembly for an instrument panel assembly as in claim 11, further comprising a light beam track extending along at least a portion of the beam path.
