Abstract
Disclosed is an outside rear-view mirror for a motor vehicle having a reverse gear. The outside rear-view mirror comprises a mirror housing adapted for being mounted to a body of the vehicle. A mirror glass is held by the mirror housing and a drive motor is provided for tilting the mirror glass about at least one axis with respect to the vehicle. The mirror is coupled to the drive motor through a link. A current supply circuit for the drive motor is provided and includes a reverse switch for reverting the direction of rotation of a rotor of the drive motor. A control member for switching the reverse gear is coupled to the reverse switch and to a preset displacement restricting device for restricting a rotation of the link. The displacement restricting device may be controlled electro-mechanically or may be formed electronically. Thereby, an inexpensive parking aid is presented to the driver which allows a view on the rearward portions of the car as an aid for rearwardly maneuvering the car into a parking space.
