Abstract
A rear-view unit for motor-vehicles, in particular commercial vehicles, has at least one external rear-view mirror with a housing and at least one mirror glass pivotably arranged in the housing. Electric servomotors are provided to pivot the mirror glasses about a positioning axis. Furthermore, heatings for the mirror glass may be available. Switches are provided to actuate the servomotors and the heating. So as to reduce the wiring and to ensure the subsequent equipment of adjustable mirror glasses with servomotors, the switches are connected to a transmitting unit and the servomotors are connected to a receiving unit of a multiplex system arranged in the housing.
