Abstract: A device for a vehicle adjustable rear-view mirror is provided, wherein the device includes a fixed portion as well as a mirror support capable of pivoting relative to the portion using a driving motor and at least one driving gear. Also a potentiometer is used for generating a signal that indicates the pivot angle between the fixed portion and the mirror support which is considered as a module. The potentiometer includes a resistive member and a wiper, one of which is coupled to a base member attached to the fixed portion while the other is connected through a friction coupling to the driving gear or to a rotating part that co-operates with the same. One of those two members comprises two abutments having an angular deviation that corresponds to the pivot angle, the fixed portion and the mirror support, while the other member comprises two counter-abutments that co-operate with said abutments.

Abstract: The invention relates to a retractable rear-view mirror for motor vehicles. Said rear-view mirror comprises a fixed base, a swiveling mirror unit and a rotation driving unit composed of a motor and a transmission. In order to minimize the friction losses while requiring a minimal space and providing a favorable assembling shape: a) the transmission of the rotation driving unit is a harmonic drive transmission having a central axis which is coaxial with the rotation axis of the mirror unit; b) said voltage wave transmission contains an eccentric means in its transmission casing, an elastic annular gear and two driven links which co-operate with said annular ring and have a different number of teeth; c) the eccentric means has a toothed work which engages the pinion gear of said motor; d) one driven link engages the base and the other driven link engages the mirror unit. The eccentric means is placed inside the elastic annular ring and the two driven links are placed outside of the elastic annular ring.

Abstract: In an adjustable rearview mirror, especially an outside mirror, for a motor vehicle, whereby a first element (1) is affixable to the vehicle and a second element (2), rotatably attached to the first element (1), has or forms a mount for a mirror (4), whereby the two elements (1, 2) are designed as dish-shaped elements (1, 2) that nest with one another at least partially and are guided or bear against one another via outside and inside areas of contact forming a segment of a spherical surface and whereby a drive (6) is provided between the first and the second element (1, 2) is proposed, characterized in that the outer element (2) is designed on part of its inner surface with a gear-tooth system extending along a circular section of the inner surface of the outer element (2), with which a pinion (8) of a drive (6) mounted in the inside of the inner element (1) meshes for adjustment of the outer element (2) relative to the inner element (1), by which means can be achieved with a simple construction a design tha
