Abstract

An improved rear view mirror usable in a vehicle, to receive impingement of light rays traveling generally forwardly from the rear, of flank, or flanks of the vehicle and to reflect said rays back toward the viewer in the vehicle which is traveling forwardly, the improvement comprising

(a) the mirror assembly having a myriad of reflecting surfaces oriented to reflect said rays, as referred to, has one of the following configurations

(N₁) convex rearwardly

(N₂) flat,

(N₃) V-shaped with apex facing rearwardly,

(N₄) flat rearwardly, in two offset sections angled relative to one another, separated by a mirror surface that is free of said myriad of surfaces,

(N₅) convex rearwardly, in two offset sections separated by a third section which is flat rearwardly,

(N₆) flat and convex, rearwardly in two laterally spaced sections, respectively, which are separated by a mirror surface that is free of said myriad surfaces,

the mirror adapted to be positioned in the vehicle cab, behind the windshield, and either symmetrically or assymmetrically with respect to the mid-line of the vehicle.

Also, a canopy may be carried by the vehicle to extend generally rearwardly above the level of the mirror and above the space immediately rearwardly of the mirror, but at or below the vehicle ceiling, the canopy absorbing light rays impinging thereon, thus to minimize ghost reflection therefrom via the mirror toward the eyes of said viewer.

Claims

1. In combination with a rear view mirror used in a vehicle and located in the cab behind the windshield, to receive impingement of light rays traveling generally forwardly from the rear, or flank, or flanks of the vehicle, and to reflect said light rays back toward the viewer in the vehicle which is traveling forwardly,

(a) a canopy carried by the vehicle to extend generally rearwardly above the level of the mirror and above the space immediately rearwardly of the mirror, but at or below the vehicle ceiling,

(b) the canopy absorbing light rays impinging thereon, thus to minimize ghost reflection thereform via the mirror toward the eyes of said viewer,

(c) the mirror having individual sectors on a transparent molding and comprising a myriad of metallized layers providing reflecting adjacent surfaces at the back side of the mirror away from the viewer, said surfaces oriented to produce, in the eyes of the viewer, one virtual image, or separate virtual images from separate portions of such molded mirror, said layers having thinned peripheries, there being a network of zones separating the individual reflecting surfaces, improvements,

(d) a material coating the back sides of said zones, and which includes a light absorber,

(e) the coating covering zones between reflecting surfaces and the thinned peripheries of said metallized reflecting layers, whereby undesirable reflections from said zones are substantially reduced.

2. The combination of claim 1 wherein the underside of the canopy is essentially non-reflective and dark.

3. The combination of claim 1 wherein the canopy is carried by structure associated with said ceiling, and is located immediately rearward of the center portion of the windshield.

4. The combination of claim 1 wherein the mirror has an associated vehicle supported holder, and the canopy is carried by said holder.

5. The combination of claim 1 wherein the canopy is positioned to intercept vehicle ceiling image light rays that would otherwise be reflected toward the viewer by a flat surface defined by a mirror backer associated with said myriad of segments.

6. The combination of claim 5 wherein the mirror has a rear side facing the viewer, and which is inclined from vertical to extend upwardly and forwardly.

7. The combination of claim 1 wherein the canopy consists of yieldable material.

8. The combination of claim 1 wherein

(f) the mirror defines a generally rearwardly facing surface inclined upwardly and forwardly, relative to vertical,

(g) and a perpendicular to the center of said surface lies in a plane which extends rearwardly and centrally of the vehicle.

9. The combination of claim 8, wherein the canopy is peripherally trapeziodal and has sheet form.

10. The combination of claim 1 wherein the canopy is located to subtend said ghost reflections reflected from a planar front surface of the mirror toward the eyes of the viewer.
