ABSTRACT:
A device for the controlled rotation of the cover of a door mirror in a motor vehicle comprises a DC fed electric motor to allow the motorized rotation of the cover and an electronic circuit enabling the electric motor. A plurality of feed tracks and a plurality of sliding contacts thereon selectively cut out or enable the connections to one or more sections of the circuit in correspondence with positions of the mirror cover different from the preset positions.
The transmission of the rotational movement from the motor to the cover is ensured by a train of gears in which one or more friction elements are inserted.
Elastic means are also foreseen for retaining and positioning the cover in respect to the fixed base, to exert, together with said friction elements, different forces of reaction that oppose the relative movement between the cover and the fixed base of the door mirror.
