Abstract
A clutch device transmits rotational energy between a drive input and a drive output, in particular between an electric actuating unit and an actuating element of an adjustable motor vehicle exterior mirror. The clutch device permits a transmission of a load torque MR from the electric actuating unit to the actuating element in both directions, and in the event of an overload torque greater than a predefined threshold torque MK, automatically permits a relative rotation between the electric actuating unit and the actuating element. Furthermore, the clutch device is designed such that, in the event of a torque direction reversal, no load torque is transmitted over a predetermined free-travel angle (φ).
