WING MIRROR UNIT, DRIVE CONSTRUCTION, AND ROTATION SENSOR

Wing mirror unit, drive construction, and rotation sensor The invention relates to a wing mirror unit (1) for a motor vehicle. The unit comprises a mirror housing support (3) for attachment to a body (4) of the motor vehicle (2). The wing mirror unit further comprises a mirror housing (5) supported by the mirror housing support and pivotably arranged with respect to said support around a rotation axis (6) extending substantially in an upward direction. Furthermore, the unit comprises a drive, preferably an electric drive, for pivoting the mirror housing between a folded-out position of the mirror housing, in which the mirror housing extends substantially in a direction (7) away from the body of the motor vehicle, and a folded-in position of the mirror housing, in which the mirror housing projects less far and extends in a substantially rearward direction more alongside the body of the motor vehicle, and/or for pivoting the mirror housing between the folded-in position and the folded-out position. The wing mirror unit also comprises a rotation sensor (8), preferably a potentiometer, having a sensor axis (9). Said unit is arranged for rotating the sensor axis during a limited part of the pivoting route between the folded-out position and the folded-in position and/or during a limited part of the pivoting route between the folded-in position and the folded-out position.
