Abstract: The invention relates to a device for damping pendulum oscillations of a trailer hitched to a coupling of a motor vehicle. For this purpose, the coupling at the rear of the motor vehicle is horizontally adjustable at right angles to the longitudinal axis of the vehicle, and damping means serve for adjusting the coupling, in proportion to the deflection of the trailer drawbar, from a position lying on the longitudinal axis of the vehicle in the direction of the side of the motor vehicle into which the trailer is swerving.Transverse movements of the coupling relatively to the superstructure of the motor vehicle cause a continuous shifting in the instantaneous fulcrum or center of rotation of the trailer drawbar forwardly along the longitudinal vehicle axis, whereby interfering forces impairing the driving direction of the trailer are counteracted and driving stability is ensured.
