Abstract

The invention is related to an interior rear view mirror that is constructed by front plastic glass shaped in u-form and a mirror housing. The mirror comprises a second plastic glass which crate a inter glass space for a device which changes the reflectivity of the mirror.

Claims

1. Rear View Mirror comprising a mirror housing and a front plastic glass, characterized in that the front plastic glass and a second plastic glass beyond the front plastic glass create an inter-glass space which comprises a mean to adapt reflectivity of the mirror and the front plastic glass is u-formed in one piece to be connected with the mirror housing and has peripheral curved edges.

2. Rear view mirror according claim 1 wherein a reflective layer covers the surface of the second plastic glass in the inter-glass space.

3. Rear view mirror according claim 1 wherein the reflective layer covers the surface of the second plastic glass outside the inter-glass space.

4. Rear view mirror according claim 1 wherein the mean to adapt reflectivity of the mirror is a cell based on electro wetting principle.

5. Rear view mirror according claim 1 wherein the mean to adapt reflectivity of the mirror is an electro chromatic device.

8. Rear view mirror according claim 1 wherein the mean to adapt reflectivity of the mirror is a switchable mirror material based on hydrogen absorbance replacing the reflective layer.

9. Rear view mirror according claim 1 wherein the mirror housing comprises a light module, with light emitting through areas of the front plastic glass side pieces.

6. Rear View Mirror comprising a mirror housing and a front plastic glass, characterized in that the front plastic glass and a second plastic glass beyond the front plastic glass create an inter-glass space which comprises a mean to adapt reflectivity of the mirror and the front plastic glass is u-formed in one piece to be connected with the mirror housing and has peripheral curved edges,

wherein the mean to adapt reflectivity of the mirror is a electro chromatic device and

wherein the electro chromatic device is a solid chemical material set.

7. Rear View Mirror comprising a mirror housing and a front plastic glass, characterized in that the front plastic glass and a second plastic glass beyond the front plastic glass create an inter-glass space which comprises a mean to adapt reflectivity of the mirror and the front plastic glass is u-formed in one piece to be connected with the mirror housing and has peripheral curved edges,

wherein the mean to adapt reflectivity of the mirror is a electro chromatic device and

wherein the electro chromatic device is polymer chemical material set with ionic liquid as electrolyte substance.

10. Rear View Mirror comprising a mirror housing and a front plastic glass, characterized in that the front plastic glass and a second plastic glass beyond the front plastic glass create an inter-glass space which comprises a mean to adapt reflectivity of the mirror and the front plastic glass is unformed in one piece to be connected with the mirror housing and has peripheral curved edges,

wherein the mirror housing comprises a light module, with light emitting through areas of the front plastic glass side pieces and

wherein the light module has at least two LEDs illuminating areas adjacent to the mirror.
