Abstract

An information display for use in vehicles including a module or housing located behind, and attached to, a support for the interior rearview mirror assembly. The module includes a display which is observable around the profile of the mirror by the vehicle operator or passengers. An upper portion of the display module is attached to the mount used to support the mirror assembly on the vehicle windshield. The upper portion of the module may be detachably coupled to the mount by a snap-on clip, by a threaded fastener secured directly to the mount, or by a resilient S-clip. The information display of this invention lends itself to quickly and inexpensively adding a wide range of information displays such as a compass, trip computer, clock, warning light, temperature readout, or the like, to any vehicle, at a location readily seen by the vehicle operator within the forward field of vision without substantially interfering or impairing the operator'"'"'s field of vision.

Claims

1. An information display for an interior rearview mirror assembly for vehicles, the vehicle being of the type including a front windshield, said display comprising:

a rearview mirror assembly including a housing holding a reflective mirror element, said housing having a peripheral edge;

a support adapted for attachment to a mounting button secured to the front windshield of the vehicle, said support including an adjustable member for adjustably mounting said housing for said reflective mirror element with respect to the mounting button; and

a module and an associated display element, said module being removably attached to said support for said rearview mirror assembly;

said module being separate from and located behind said housing for said reflective mirror element and adapted to be concealed by said housing, said display element being mounted on said module such that said display element is exposed by said peripheral edge of said housing and is observable by an occupant of the vehicle;

said housing being adjustably mounted on said adjustable member of said support whereby the position of said housing is adjustable independent of the location of said module and display on said support.

2. An information display as claimed in claim 1, wherein said module includes a module housing having a lobe extending beyond said peripheral edge of said housing for said reflective mirror element, said display element being located in said lobe.

3. An information display as claimed in claim 2, wherein said module housing includes first and second portions joined together to define an interior chamber.

4. An information display as claimed in claim 3, further including a circuit in said module housing for powering said display element, and a conductor means for connecting said circuit to a power source.

5. An information display as claimed in claim 4, wherein said circuit comprises at least one device selected from the group of devices comprising compasses, odometers, clocks, trip computers, global satellite positioning systems, cellular telephones, supplemental vision systems, warning lights, turn indicators, hazard warning indicators, speed indicators, and indicia.

6. An information display as claimed in claim 1, wherein said display element includes at least one of a liquid crystal display, a light-emitting diode, and a fluorescent element.

7. An information display as claimed in claim 1 wherein said support further includes a mount adapted to engage the mounting button when the mounting button is secured to the inside surface of the front windshield;

said module including a coupler engaging said mount.

8. An information display as claimed in claim 7 wherein said coupler includes a first member engaging said mount and a second member engaging a portion of said support spaced from said mount.

9. An information display as claimed in claim 7, wherein said coupler includes a shafted fastener received in said mount.

10. An information display as claimed in claim 7, wherein said coupler includes a slide fastner received in said mount.

11. An information display as claimed in claim 1 wherein said reflective mirror element is an electro-optic mirror element whose reflectivity is variable depending upon the application of an electrical voltage thereacross.

12. An information display as claimed in claim 11 wherein said electro-optic mirror element includes an electrochromic mirror element.

13. An information display as claimed in claim 11, wherein said rearview mirror assembly includes at least one of a map light and an automatic dimming circuit.

14. An information display for an interior rearview mirror assembly for vehicles, the vehicle being of the type including a front windshield, said display comprising:

a rearview mirror assembly including a housing holding a reflective mirror element;

a support adapted to extend from a position adjacent the vehicle front windshield to said housing, said housing having a peripheral edge; and

a module and an associated display element, said module being removably attached to said support for said rearview mirror assembly;

said module being separate from and located behind said housing for said reflective mirror element such that at least said display element is exposed by said peripheral edge of said housing and is observable by an occupant of the vehicle;

said support including a mount adapted to engage a button secured to the inside surface of said windshield;

said module including a coupler engaging said mount;

said coupler including a first member engaging said mount and a second member engaging a portion of said support spaced from said mount;

said first member being a tab on one end of said coupler for catching said mount and said second member being a clip for snapping over a neck on said support.

15. An information display for an interior rearview mirror assembly for vehicles, the vehicle being of the type including a front windshield, said display comprising:

a rearview mirror assembly including a housing holding a reflective mirror element;

a support adapted to extend from a position adjacent the vehicle front windshield to said housing, said housing having a peripheral edge;

a module and an associated display element, said module being removably attached to said support for said rearview mirror assembly;

said module being separate from and located behind said housing for said reflective mirror element such that at least said display element is exposed by said peripheral edge of said housing and is observable by an occupant of the vehicle; and

said support including a mount adapted to engage a button secured to the inside surface of said windshield;

said module including a coupler engaging said mount;

said coupler including an attachment member for snapping said module onto said mount.

16. An information display for an interior rearview mirror assembly for vehicles, the vehicle being of the type including a front windshield, said display comprising:

a rearview mirror assembly including a housing holding a reflective mirror element;

a support adapted to extend from a position adjacent the vehicle front windshield to said housing, said housing having a peripheral edge;

a module and an associated display element, said module being removably attached to said support for said rearview mirror assembly;

said module being separate from and located behind said housing for said reflective mirror element such that at least said display element is exposed by said peripheral edge of said housing and is observable by an occupant of the vehicle; and

said support including a mount adapted to engage a button secured to the inside surface of said windshield;

said module including a coupler engaging said mount;

said support also including a support arm having two ends and pivotally connected to said mount at one of said ends and pivotally connected to said housing for said reflective mirror element at the second of said two ends whereby said rearview mirror assembly including said housing for said reflective mirror element and said reflective mirror element is adjustable independent of the location of said module and display.
