<p>The coupling has a coupling neck (1) with an end connected with a coupling ball (3) and rotatably supported for rotating a bumper around a horizontal rotation axis (2). The coupling neck exhibits a circular-arc-shaped section (8) having radius that corresponds to distance of the rotation axis to a lowest point of the coupling neck in a working position. The coupling neck exhibits a radial section having length that corresponds to radius of a circular arc of the circular-arc-shaped section with respect to the axis. The neck is manufactured from a band shaped material i.e. flat-bar steel. An independent claim is also included for a device for arrangement at a rear end of the vehicle, comprising a bumper with an outside bumper section.</p> |
