Abstract

A rear view mirror (1) for a motor vehicle comprising a metal-coated substrate (2) which forms a main mirror surface (4) and is provided in a subarea with an additional blind spot mirror (6) is to provide a particularly high reproduction quality of the reflected image, while production costs are kept down. For this purpose, according to the invention, the additional blind spot mirror (6) is bonded onto the side of the substrate (2) remote from the direction of light incidence on the substrate (2) by a transparent, light-resistant adhesive.

Claims

1. A rear view mirror for a motor vehicle comprising

a metal-coated substrate which forms a main mirror surface and is provided in a subarea with an additional blind spot mirror, the additional blind spot mirror being bonded onto the side of the substrate opposite from the direction of light incidence on the substrate by a transparent, light-resistant adhesive, wherein

the substrate is metal-coated on its side opposite from the direction of light incidence and the additional blind spot mirror is metal-coated on its side facing the direction of light incidence.

2. The rear view mirror according to claim 1, wherein a number of spacers are arranged between the metal-coated substrate and the additional blind spot mirror.

3. The rear view mirror according to claim 1, wherein the additional blind spot mirror is produced from a metal-coated calotte which, compared to the metal-coated substrate, has a smaller radius of curvature.

4. The rear view mirror according to claim 3, wherein the smaller radius of curvature is less than 1000 mm.

5. The rear view mirror according to claim 1, wherein the additional blind spot mirror has an average thickness of 1.6 mm at the most.

6. The rear view mirror according to claim 1, wherein a silicone or an acrylate is provided as adhesive.

7. The rear view mirror according to claim 1, the back of which is bonded with a heating foil.

8. The rear view mirror according to claim 7, the heating foil of which has slots in the region of the additional blind spot mirror.

9. A method for producing a rear view mirror according to claim 1, wherein a substrate provided to form the main mirror surface is provided with a mask in a subarea and is then metal-coated by applying a reflector material, leaving the subarea free, and wherein an additional blind spot mirror is bonded onto the subarea after the mask has been removed.
