Electrically rotary adjustment unit, in particular for indirect vision systems for vehicles

摘要

Electrically rotary adjustment unit, in particular for indirect vision systems for vehicles, with a base part (1), a part that must be rotated (3) that is axially rotatable, an electric rotation drive (7) connected to the base part (1), which can be coupled with the part to be rotated (3), to rotate the part to be rotated electromotive (3) and a coupling device (11; 110, 17, 23 ), which is provided between the base part (1) and the part to be rotated (3), characterized in that the coupling device (11; 110, 17, 23) between the base part (1) and the part which must be turned (3) in the zero position, in which the electric rotation drive (7) is deactivated, mutually engages the base part (1) and the part that must be turned (3) in a torsionally resistant manner and decouple the electric rotation drive (7) from the part to be turned (3), and because the device coupling (11; 110, 17, 23), upon activation of the electric rotation drive (7), undock the base part (1) of the part to be turned (3) and attach the electric rotation drive (7) to the part that should be turn (3).
