Abstract

The invention relates to interior rear view mirrors, in the mirror housing (1) of which sensors are disposed that sit on an electronic board (13). Said rear view mirrors require substantial assembly space such that the assembly position of the sensor is limited. In order not to restrict the assembly position of the sensor, said sensor sits on a sensor board (12) that is separate from the electronic board (13). The two boards (12, 13) are interconnected by means of signals. The sensor board (12) can be embodied in a very compact manner such that the sensor located thereupon can be mounted in any appropriate position within the mirror housing (1). The interior rear view mirror is used for motor vehicles.

Claims

1. Interior rearview mirror for vehicles, comprising:

a mirror housing in which is accommodated at least one electronics circuit board for at least one sensor, said sensor being arranged in the detection region for signals arriving at the interior rearview mirror from outside, wherein the sensor is seated on a sensor circuit board that is spatially separated from, and connected by signals to, the electronics circuit board.

2. Interior rearview mirror according to claim 1, wherein the sensor circuit board is arranged in the region between an actuator drive of the interior rearview mirror and a mirror glass.

3. Interior rearview mirror according to claim 1, wherein the sensor circuit board is attached at the edge of the mirror housing.

4. Interior rearview mirror according to claim 1, wherein the sensor circuit board and the electronics circuit board are connected to one another by at least one flexible line.

5. Interior rearview mirror according to claim 4, wherein the flexible line is a conductive trace.

6. Interior rearview mirror according to claim 1, wherein the sensor circuit board is wirelessly connected by signals to the electronics circuit board.

7. Interior rearview mirror according to claim 1, wherein the sensor is accommodated in a receiving opening in the edge of the mirror housing.

8. Interior rearview mirror according to claim 1, wherein the sensor is centered on the edge of the mirror housing.

9. Interior rearview mirror according to claim 1, wherein the sensor is an EC headlight glare sensor.

10. Interior rearview mirror according to claim 1, wherein the mirror housing has a frame and a cover connected therewith.

11. Interior rearview mirror according to claim 1, wherein the mirror glass is an EC mirror glass.
