Abstract: An adjusting instrument for electrically adjusting the interior mirror of a motor vehicle about two mutually perpendicular axes. The device comprises a vehicle-connectable suspension device and a mirror mounting plate connected thereto. The plate is adjustable about two mutually perpendicular axes and supports a rearview mirror. The suspension device comprises a housing accommodating two drive units whose output shafts are perpendicular to one another and geared to drive the mirror mounting plate. The drive units are arranged to exert a torque on the point of suspension of the suspension device, that is equal but opposite to the torque exerted on the point of suspension by the mirror mounting plate and mirror.

Abstract: An adjusting device with an overload slip system and a slip-independent position indicator includes a driving system and an adjusting member movable by the driving system between two end stops. The driving system includes an electric motor housed in a housing and a planetary transmission connected to the motor shaft, the power output shaft of the transmission being in engagement with the adjusting member. A stationary, internally toothed ring of the planetary transmission is confined between facing peripheral edges of the divided housing and is capable of slipping relatively to the edges of the housing under overload conditions. A support plate with a circular electrical resistor is fixedly connected to the housing on the side of the power output shaft. A runner contact connected to the power output shaft is movable over the resistor.

Abstract: A device for adjusting the mirror of an automotive vehicle, as disclosed in U.S. Pat. No. 4,116,538, includes drive and transmission devices consisting of two motors, each provided with a planetary transmission system mounted on a motor shaft, the two motor transmission systems being arranged mirror-symmetrically relatively to a median plane of a housing, the median plane containing the axis of a stiffening element.
