Device for controlling the rotation of a door mirror up to preset position
First Claim
1. A device for the controlled rotation of the outer cover of a door mirror mounted on a casing turning with respect to a fixed base, between an initial position and one or more preset positions, the device including a DC electric motor for the motorized rotation of the mirror cover and at least a couple of control buttons to actuate the motorized rotation of said cover wherein the improvement comprises an electronic enabling circuit comprising:
- at least a couple of relays connected through a plurality of diodes for allowing reversal of current polarity to the terminals of said motor;
an actuating section for supplying power to said electric motor during a preset period of time;
a plurality of feed tracks and a plurality of sliding contacts on said tracks to selectively interrupt or to enable connections to one or more sections of the circuit in correspondence to positions of the mirror cover different from said preset positions.

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.
