Abstract

A rearview mirror assembly incorporating one or more vehicle information displays includes an information display area in a portion of the rearview mirror housing which is at an angle to the plane of the reflective mirror element to provide improved visibility of the display by a front seat passenger. The information display can be provided in either the chin or eyebrow area of the rearview mirror housing, in the end of the mirror housing, or, alternately, in the field of view of the reflective mirror element itself or as a combination thereof. Such rearview mirror assemblies can be used in combination with a rearview mirror support and information display assembly including a rigid mirror stay preferably having a mirror support for independently adjustably mounting the rearview mirror assembly, and may also include a breakaway mount which releasably couples the stay and the supported rearview mirror assembly to a windshield mounted button or a header mounted base such that the entire assembly is released upon impact. The information display is especially useful to provide the operational status of the Passenger Side Inflatable Restraint (PSIR) or air bag.

Claims

1. A rearview mirror assembly for vehicles, said assembly comprising a rearview mirror and a support for mounting said assembly on a vehicle;

said rearview mirror having a driver side end and a passenger side end, said driver side end adapted to be closer to the position of the vehicle driver when said rearview mirror is mounted in a vehicle on said support, said passenger side end adapted to be closer to the position of a front seat passenger in the vehicle when said rearview mirror is mounted in the vehicle on said support, said rearview mirror including a reflective mirror element having a front surface which lies in a mirror plane and faces the interior of the vehicle, and a housing for said mirror element, said housing being adjustably mounted to said support, said housing including a back portion facing away from the vehicle interior, end portions, and a front portion facing the vehicle interior;

said assembly also including an information display providing information to an occupant of the vehicle and having a display plane, said display plane being at an angle to said mirror plane to provide improved visibility of said display by a front seat passenger in the vehicle when said assembly is mounted on the vehicle.

2. The rearview mirror assembly of

claim 1

wherein said display is included on said front portion of said housing.

3. The rearview mirror assembly of

claim 2

wherein said front portion of said housing includes a peripheral edge;

said display being positioned at said peripheral edge of said housing.

4. The rearview mirror assembly of

claim 3

wherein said display at said peripheral edge is positioned below said reflective mirror element.

5. The rearview mirror assembly of

claim 3

wherein said display at said peripheral edge is positioned above said reflective mirror element.

6. The rearview mirror assembly of

claim 3

wherein said display is recessed within said housing.

7. The rearview mirror assembly of

claim 2

wherein said display protrudes away from said housing.

8. The rearview mirror assembly of

claim 1

wherein said display includes a display element having indicia thereon and at least one light source mounted behind said display element for backlighting said indicia.

9. The rearview mirror assembly of

claim 8

wherein said light source is selected from the group consisting of a light emitting diode, an electroluminescent light source, and an electrophosphorescent light source.

10. The rearview mirror assembly of

claim 1

wherein said information display is on a portion of said housing;

said reflective mirror element including a second information display formed as a non-reflective portion within the field of view of said reflective mirror element.

11. The rearview mirror assembly of

claim 10

including indicia on said second information display and at least one light source mounted behind said second display for backlighting said indicia thereon.

12. The rearview mirror assembly of

claim 1

wherein said display is included on one of said end portions of said housing.

13. The rearview mirror assembly of

claim 1

wherein said angle of said display plane to said mirror plane is within the range of about 15°

and 30°

.

14. The rearview mirror assembly of

claim 13

wherein said angle of said display plane to said mirror plane is greater than 30°

.

15. The rearview mirror assembly of

claim 13

wherein said angle of said display plane to said mirror plane is less than 15°

but greater than 0°

.

16. A rearview mirror assembly for vehicles, said assembly having a driver side end and a passenger side end, said driver side end adapted to be closer to the position of the vehicle driver when said assembly is mounted in a vehicle on a mirror support, said passenger side end adapted to be closer to the position of a front seat passenger in the vehicle when said assembly is mounted in the vehicle, said assembly comprising:
