Abstract

An interior rearview mirror assembly provides a display system for displaying light or information to a driver of a vehicle. The display includes a refractive light directing element, which may include a prismatic display lens which refracts and directs the light of the display message downwardly and/or sidewardly toward a driver of the vehicle for improved viewing of the display message by the driver of the vehicle. The display system is mountable to a printed circuit board positioned within the case of the mirror assembly. The printed circuit board may also be connected to a pair of illumination sources positioned at a lower portion of a casing of the mirror assembly.

Claims

1. An interior rearview mirror assembly for a vehicle, said mirror assembly comprising:

a mirror case having a reflective element, said mirror case being adapted to mount to an interior portion of the vehicle;

an information display element positioned within said mirror case, said information display element being operable to project at a first location a light pattern indicative of information desired to be displayed, the projected light pattern being generally not readily viewable at said first location by a driver of the vehicle; and

a refractive light directing element positioned at a perimeter of said reflective element and generally adjacent to said information display element, said refractive light directing element being configured to refract the light pattern projected by said information display element, said refraction of the projected light pattern by said refractive light directing element causing the projected light pattern to be displaced to a second location more readily viewable by the driver of the vehicle.

2. The interior rearview mirror assembly of claim 1, wherein said refraction of the projected light pattern causes the projected light pattern to be displaced generally laterally toward a driver side of the vehicle.

3. The interior rearview mirror assembly of claim 1, wherein said refractive light directing element has a first thickness at an upper portion and a second thickness at a lower portion, said first thickness being greater than said second thickness.

4. The interior rearview mirror assembly of claim 1, wherein said information display element is removably mounted within said mirror case.

5. The interior rearview mirror assembly of claim 1, wherein said refractive light directing element is positioned along a lower portion of said mirror case.

6. The interior rearview mirror assembly of claim 1, wherein said mirror assembly is mountable at a mounting base on an interior surface of a windshield of the vehicle.

7. The interior rearview mirror assembly of claim 6, wherein said mirror assembly is mounted at said mounting base via a double ball mounting arm being pivotally mounted between said mirror case and said mounting base.

8. The interior rearview mirror assembly of claim 1, wherein said mirror assembly comprises a prismatic mirror which is pivotable via a toggle assembly between a day and night reflective position.

9. The interior rearview mirror assembly of claim 8, wherein said toggle assembly comprises a soft touch toggle handle.

11. The interior rearview mirror assembly of claim 9, wherein said soft touch toggle handle is formed by a two shot molding process.

12. The interior rearview mirror assembly of claim 11, wherein said two shot molding process includes molding an inner portion having a first hardness and molding an outer portion having a second hardness over said inner portion, said first hardness being greater than said second hardness.

14. The interior rearview mirror assembly of claim 1 further including at least one map light assembly positioned at a lower region of said case.

15. The interior rearview mirror assembly of claim 14 including a pair of said map light assemblies, said map light assemblies comprising a right and left map light, each map light including an illumination source, a reflector element, and a cover, at least a portion of said right and left map lights being interchangeable with one another.

16. The interior rearview mirror assembly of claim 14, wherein said map light assemblies are removably mounted at said case.

17. The interior rearview mirror assembly of claim 1 further including at least one control input for at least one of an accessory and said information display element, said control input being positioned at said case.

18. The interior rearview mirror assembly of claim 17, wherein said control input is at least one of operable to activate said information display element, operable to deactivate said information display element and operable to toggle said information display element between two or more functions.

19. The interior rearview mirror assembly of claim 17, wherein said at least one control input is backlit by an illumination source positioned within said case.

10. An interior rearview mirror assembly for a vehicle, said mirror assembly comprising:

a mirror case having a reflective element, said mirror case being adapted to mount to the vehicle;

a light emitting display element positioned within said mirror case and operable to project light in a direction generally rearwardly with respect to the vehicle; and

a refractive light directing element positioned at a perimeter of said reflective element and generally adjacent to said display element, said refractive light directing element refracting the light from said display element generally downwardly and rearwardly toward a driver of the vehicle, said mirror assembly comprising a prismatic mirror which is pivotable via a toggle assembly between a day and night reflective position, said toggle assembly comprising a soft touch toggle handle, wherein said soft touch toggle handle comprises an inner material and an outer material over said inner material, said outer material having a material hardness of less than approximately 70 Shore A Durometer hardness.

13. An interior rearview mirror assembly for a vehicle, said mirror comprising:

a mirror case having a reflective element, said mirror case being adapted to mount to the vehicle;

a light emitting display element positioned within said mirror case and operable to project light in a direction generally rearwardly with respect to the vehicle; and

a refractive light directing element positioned at a perimeter of said reflective element and generally adjacent to said display element, said refractive light directing element refracting the light from said display element generally downwardly and rearwardly toward a driver of the vehicle, said mirror assembly comprising a prismatic mirror which is pivotable via a toggle assembly between a day and night reflective position, said toggle assembly comprising a soft touch toggle handle, said soft touch toggle handle being formed by a two shot molding process, said two shot molding process including molding an inner portion having a first hardness and molding an outer portion having a second hardness over said inner portion, said first hardness being greater than said second hardness, wherein said second hardness is less than approximately 70 Shore A Durometer hardness and said first hardness is greater than approximately 70 Shore A Durometer hardness.

20. A prismatic interior rearview mirror assembly for a vehicle, said mirror assembly comprising:

a mirror case having a reflective element, said mirror case being adapted to mount to a vehicle via a mounting arm, said mirror case being pivotable relative to said mounting arm; and
