Abstract

The invention related to a rear view mirror using a plastic glass material to combine several functions as fixing and heating.

Claims

1. A rear view mirror, comprising a housing an motor actuator and a reflective element, wherein the reflective element is a plastic material substrate with a first surface coated with at least a reflective layer and a second surface with at least a set of molded fixing elements to be fixed at the motor actuator, said set of molded fixing elements includes molded contact noses for heater contacts.

2. A rear view mirror according to claim 1 wherein the edge radius along the rim of the mirror shape has a value of more than 0.6 mm.

3. A rear view mirror according to claim 1 wherein the plastic material substrate includes a frame area along the rim of the mirror substrate shape with an increased thickness.

4. A rear view mirror according to claim 1 wherein the reflective layer is an Al—

Ti layer.

5. A rear view mirror, according to claim 1 wherein the reflective element includes a protection hard coat layer with a first and a second layer of the same hard coat material, the first layer deposited by a dipping process, the second layer applied by a spraying process.

6. A rear view mirror according to claim 5 wherein the first hard coat layer is smooth with a roughness smaller than wavelengths of visible light.

7. A rear view mirror according to claim 1 wherein the second surface is coated with a heating resistive alloy of Ti—

Al or Ni—

Ti.

8. A rear view mirror, comprising a housing an motor actuator and a reflective element, wherein the reflective element is a plastic material substrate with a first surface coated with at least a reflective layer and a second surface with at least a set of molded fixing elements to be fixed at the motor actuator, wherein the second surface is coated with a heating resistive alloy of Ti—

Al or Ni—

Ti, with a plurality of spaced apart electrodes attached to the heating resistive layer, said electrodes being adapted to induce a current through the heating resistive layer between, wherein the electrodes are located on a same side of the substrate and are disposed in the immediate vicinity of each other.

9. A rear view mirror, comprising a housing an motor actuator and a reflective element, wherein the reflective element is a plastic material substrate with a first surface coated with at least a reflective layer and a second surface with at least a set of molded fixing elements to be fixed at the motor actuator, wherein the second surface is coated with a heating resistive alloy of Ti—

Al or Ni—

Ti, characterized in that it comprises two electrodes provided in the form of strips of electrically conducting material, for example copper-based, and the heating resistive layer is formed of a metal alloy, the electrodes being electrically insulated from the heating resistive layer by an insulating mean.
