Abstract

An extending and rotating rearview mirror assembly for use on an automotive vehicle includes a base member (

34) for mounting the mirror assembly to the vehicle. An elongated support arm (

38) is pivotally mounted to the base member for pivoting the mirror assembly between an operative position and a folded position. The support arm supports a mirror housing (

30) having a glass mirror pane (

24) therein for providing a rearward reflective view from the vehicle. A coupling assembly (

20) interconnects the mirror housing and support arm for sliding mirror housing in a generally horizontal direction with respect to the base member and for rotating the mirror housing with respect to the base member.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

Other advantages of the present invention will be readily appreciated when the same becomes understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is an exploded view of a rearview mirror assembly constructed according to the principles of the present invention;

FIG. 2 is an isolated elevational view of a support arm of the rearview mirror assembly;

FIG. 3 is an enlarged exploded view of a portion of the rearview mirror assembly showing a housing assembly and the support arm thereof;

FIG. 4 is an exploded view similar to the view of FIG. 3 but showing an opposite view thereof,

FIG. 5 is an isolated view of the rearview mirror assembly showing a mirror body thereof in a fully inwardly position;

FIG. 6 is a cross-sectional view of the mirror assembly taken through the line

6

6 of FIG. 5 with a power pack assembly and a mirror element removed to more clearly illustrate portions of the invention;

FIG. 7 is a view of the rearview mirror assembly similar to the view of FIG. 5, but showing the mirror body in a fully outwardly extended position;

FIG. 8 is a view of the rearview mirror assembly similar to the view of FIG. 7, but showing the mirror body rotated generally vertically upwardly from a mounting assembly thereof;

FIG. 9 is a view of the rearview mirror assembly similar to the view of FIG. 8, but showing the mirror body rotated generally vertically downwardly from the mounting assembly;

FIG. 10 is a view of a second embodiment of a rearview mirror assembly similar to the view of the first embodiment shown in FIG. 7 except showing in addition a plurality of optional microswitches mounted in the support arm;

FIG. 11 is an enlarged fragmentary perspective view of a coupling assembly of the support arm; and

FIG. 12 is an enlarged fragmentary perspective view of the coupling assembly of the mirror body.

Claims

1. A rearview mirror assembly for a vehicle comprising:

2. A rearview mirror assembly as set forth in claim 1 wherein said mounting assembly includes an elongated support arm extending between a proximal end and a distal end for mounting said mirror body thereto.

3. A rearview mirror assembly as set forth in claim 2 wherein said coupling assembly includes an elongated slot formed in said support arm and extending between a first arcuate end and second arcuate end between said proximal and distal ends of said support arm.

4. A rearview mirror assembly as set forth in claim 3 wherein said coupling assembly includes a tubular pivot post projecting from said mirror housing and slidably received within said elongated slot for lateral movement between said first and second arcuate ends.

5. A rearview mirror assembly as set forth in claim 4 wherein said elongated slot is bordered by upper and lower upstanding walls interconnected by an arcuate shaped wall portion adjacent said first arcuate end and a circular shaped wall portion adjacent to and surrounding said second arcuate end of said slot.

6. A rearview mirror assembly as set forth in claim 5 further including a planar shelf extending between the peripheral edge defining said slot and each of said upper and lower upstanding walls, said arcuate shaped wall portion and said circular shaped wall portion.

7. A rearview mirror assembly as set forth in claim 6 further including a plurality of equally spaced apart releasable rotation preventing elements projecting from said shelf adjacent said circular shaped wall portion.

8. A rearview mirror assembly as set forth in claim 7 wherein said mirror housing includes a rear wall opposite said opening and said coupling member includes a guide member projecting from said rear wall and surrounding said pivot post for mating alignment between said upper and lower walls adjacent said slot.

9. A rearview mirror assembly as set forth in claim 8 wherein said guide member includes raised upper and lower straight rail portions interconnected at their opposing ends by inner and out arcuate rail portions.

10. A rearview mirror assembly as set forth in claim 9 wherein said guide member includes a notch formed at a central position in each arcuate wall portion thereof to releasably receive one of said rotation preventing elements therein to define a rotated position of said mirror body.

11. A rearview mirror assembly as set forth in claim 10 wherein each of said rotation preventing elements includes a forwardly facing ramp surface and a rearwardly facing ramped surface extending from opposing sides of a central surface for cooperation with said notch in said guide member to define said rotated position.

12. A rearview mirror assembly as set forth in claim 11 wherein each notch includes opposing ramped surface extending between a central surface an a top edge of said respective adjacent rail portion for mating with said ramp surfaces of said rotation preventing elements.

13. A rearview mirror assembly as set forth in claim 12 further including a spring bias element seated around said pivot post between said shelf and a retaining nut opposite said guide member for slidably securing said mirror housing to said support arm and guide member against said shelf.

14. A rearview mirror assembly as set forth in claim 13 further including a base member for operatively supporting said support arm and mirror housing and adapted to mount said mirror assembly to the vehicle.

15. A rearview mirror assembly as set forth in claim 14 wherein said base member includes a tubular collar projecting upwardly from a support plate for rotatably receiving and supporting said support arm thereon and for providing rotation movement of said support arm and mirror housing relative to said vehicle.
