Abstract

An accessory arrangement for an inside and an outside mirror includes a two-part hollow member with one part being a spherical mirror section. A peripheral shoulder on one part snaps into a peripheral groove on the other part.

Claims

1. An accessory arrangement for an inside mirror and an outside mirror with reflecting means having a plane mirror surface on motor vehicles, comprising:

an outside mirror on a vehicle, a mirror unit fastened on the inside of the vehicle and opposite said outside mirror, said mirror unit displaying space outside of said vehicle through an adjacent window pane, said mirror unit comprising a two-part hollow member having a housing with a peripheral mounting, said housing being covered by a wall formed as a spherical section projecting from said housing, said wall having a mirror surface corresponding in size to the size of a regular rearview mirror and having a rim bent backwards, said rim being chamfered at its free end, said rim having a radially projecting peripheral shoulder engaging a peripheral groove of said mounting of said housing.

2. An arrangement as defined in claim 1 wherein the area outside of the vehicle is visible to a driver of the vehicle without interference from a simultaneous view of the interior of the vehicle, estimating of the distance between said vehicle and another vehicle being possible from viewing said outside mirror and said mirror unit, said spherical section enlarging the outside area to be viewed and being operational substantially independent of position.

3. An arrangement as defined in claim 1 wherein said mirror surface has a curvature with radius of substantially 90 mm.

4. An arrangement as defined in claim 1 wherein said mirror surface has a curvature with span width of substantially 80 mm.

5. An arrangement as defined in claim 1 wherein said mirror unit with said mirror surface is located in region of both sides of the vehicle, said mirror surface being convex curved.

6. An arrangement as defined in claim 1 including hinge joint means and mounting plate means, said housing being fixed to said mounting plate means by said hinge joint means.

7. An arrangement as defined in claim 6 wherein said hinge joint means comprises an adjustable screw.

8. An arrangement as defined in claim 1 wherein said wall holding said mirror surface comprises a plastic injection molded member which is electrolytically plated.

9. An arrangement as defined in claim 2 wherein said housing and said wall are held together by snap-in closure free of projecting flanges.

10. An arrangement as defined in claim 1 wherein the area outside of the vehicle is visible to a driver of the vehicle without interference from a simultaneous view of the interior of the vehicle, estimating of the distance between said vehicle and another vehicle being possible from viewing said outside mirror and said mirror unit, said spherical section enlarging the outside area to be received and being operational substantially independent of position, said housing and said wall being held together by snap-in closure free of projecting flanges, said mirror surface having a curvature with radius of substantially 90 mm, said mirror surface having a span width of substantially 85 mm, said mirror unit being located in region of both sides of a vehicle, hinge joint means and mounting plate means, said housing being fixed to said mounting plate means by said hinge joint means, said hinge joint means comprising an adjustable screw, said wall comprising a plastic injection molded member, said mirror surface being an electrolytically plated surface, said housing having an integrally formed tongue portion, said mounting plate means having an integrally formed fork-shaped portion for receiving said tongue portion, said tongue portion and said fork-shaped portion being connected by said adjustable screw and being adjustable forwards and backwards for adjusting the distance of the mirror unit from the neighboring window of said vehicle.
