Abstract
A trailer coupling for motor vehicles, in particular passenger vehicles, has a coupling ball and a ball neck. One end region of the neck is angled and bears the coupling ball. Using a drive motor, the ball neck is movable with the coupling ball from an operative position into a rest position, and vice versa. To operate as safely as possible, a control (e.g., interlock) is provided for operating the drive to allow either movement of the ball neck, or traveling of the motor vehicle, but not both at the same time.
