Abstract

An outside rear-view mirror for a vehicle, which is designed to support an image-detector device is disclosed. The assembly comprises a casing with a reflector fastening device and a detector fastening device configured to mount either a first reflector installed over the detector fastening device, hiding them, or a second reflector, smaller than the first one, leaving the detector fastening device clear and available for the installation of the image detector device in operating conditions.

Claims

1. A vehicle exterior rear view mirror assembly prepared to carry an image detector device comprising:

a casing in which at least one reflector is installed providing a reflected rear image visible by a vehicle occupant;

a support base to fix said casing with said reflector to a part of the vehicle;

reflector fastening means to support on said casing either a first reflector of a first size or a second reflector of a second size, said second size being smaller than said first size; and

detector fastening means to support on said casing said image detector device, which is adapted to provide a signal representative of a rear image susceptible to be processed and presented as an information to a vehicle occupant,

wherein said reflector and detector fastening means are configured and disposed such that when said first reflector is mounted on the reflector fastening means, the first reflector overlaps the detector fastening means, hiding them; and

when said second reflector is mounted on the reflector fastening means, the detector fastening means are available for the installation of said image detector device in operating conditions.

2. The rear view mirror assembly according to claim 1, wherein the casing defines at least one cavity accessible through a wide opening limited by an inner contour, the reflector and detector fastening means being located in said at least one cavity.

3. The rear view mirror assembly according to claim 2, wherein the first reflector is provided with an external contour which conforms to said inner contour of said opening of the cavity with a clearance.

4. The rear view mirror assembly according to claim 2, further comprising an adapter provided with an orifice through which the image detector device acquires information, said adapter being complementary to the second reflector and having a first outer contour portion conformed to a portion of the inner contour of the cavity opening of the casing and a second outer contour portion cooperating with the remaining portion of the inner contour of the cavity in order to define a new inner contour, of smaller size, to which an outer contour of the second reflector conforms with a clearance.

5. The rear view mirror assembly according to claim 4, wherein the image detector device is mounted to said adapter, which is configured to be fixed in the detector fastening means.

6. The rear view mirror assembly according to claim 5, wherein the adapter and the image detector device comprise fastening and centering means which cooperate with each other to maintain the image detector device in an appropriate position facing said orifice.

7. The rear view mirror assembly according to claim 6, wherein said fastening and centering means include an auxiliary chassis provided with first configurations to fasten the image detector device and second configurations adapted to fix the auxiliary chassis to the adapter or to a back wall of the cavity by means of the detector fastening means.

8. The rear view mirror assembly according to claim 4, wherein the adapter and the image detector device do not protrude from an outer edge of the cavity opening of the casing.

9. The rear view mirror assembly according to claim 4, wherein said second outer contour portion of the adapter is concave.

10. The rear view mirror assembly according to claim 4, wherein said second outer contour portion of the adapter is convex.

11. The rear view mirror assembly according to claim 4, wherein said second outer contour portion of the adapter is substantially straight.

12. The rear view mirror assembly according to claim 4, wherein the adapter Comprises a visor configuration adjacent to an upper part of said orifice for protection against environmental agents.

13. The rear view mirror assembly according to claim 12, wherein the adapter comprises a gutter configuration adjacent to a lower part of said orifice for protection against environmental agents.

14. The rear view mirror assembly according to claim 13, wherein said gutter configuration has a lower portion inclined at an angle of at least 45°

from the horizontal.

15. The rear view mirror assembly according to claim 13, wherein said visor configuration and/or said gutter configuration protrude with respect to the orifice a distance equal to or greater than the orifice diameter.

16. The rear view mirror assembly according to claim 4_, wherein the orifice of the adapter is closed by a transparent elements.

17. The rear view mirror assembly according to claim 4, wherein the adapter further comprises an auxiliary reflectors.

18. The rear view mirror assembly according to claim 2, wherein the reflector fastening means are integrated in an actuator device located in the cavity, in order to selectively move the reflector in relation to the casing.

19. The rear view mirror assembly according to claim 18, wherein said actuator device includes at least one electric motor.

20. The rear view mirror assembly according to claim 4, wherein the casing comprises a inner back wall defining said cavity and a frame that defines said wide opening limited by said inner contour.

21. The rear view mirror assembly according to claim 20, wherein said inner back wall is provided with at least one opening to facilitate access to at least one connection wiring of the image detector device

22. The rear view mirror assembly according to claim 20, wherein said frame is integral with a convex shell that completes the casing and said inner back wall is a piece coupled to the interior of said convex shell through the wide opening limited by said inner contour.

23. The rear view mirror assembly according to claim 20, wherein a removable convex cover is coupled to at least a part of said frame at an opposite side of the cavity, said removable convex cover covering said inner back wall at its exterior part and completing the casing.

24. The rear view mirror assembly according to claim 23, wherein the image detector device is mounted on the rear part of said inner back wall, for that the inner back wall comprises at least one opening for the image detector device in relationship with the detector fastening means, which include fastening and centering means to maintain the image detector device in an appropriate position facing said orifice of the adapter.

25. The rear view mirror assembly according to claim 24, wherein an auxiliary chassis is provided with first configurations to fasten the image detector device and second configurations adapted to fix said auxiliary chassis to the inner back wall, said first and second configurations acting as said fastening and centering means.

26. The rear view mirror assembly according to claim 5, wherein the orifice of the adapter is closed by a transparent element.

27. The rear view mirror assembly according to claim 6, wherein the orifice of the adapter is closed by a transparent element.

28. The rear view mirror assembly according to claim 7, wherein the orifice of the adapter is closed by a transparent element.
