Abstract: Method for braking a vehicle which has gone out of control, in which vehicle parts come into operative connection with an impact body which can be moved in the deceleration direction, wherein the impact body is connected to a controllable hydromechanical force converter and the vehicle is braked with a constantly controlled deceleration force until it reaches a standstill, wherein a measuring and control device provided in the region of the impact body controls the deceleration force of the force converter, independently of the impact mass of the respective vehicle.

Abstract: A hitch to be used with a one-wheeled trailer to be towed by a bicycle, motorcycle, moped, or other cycle or two-wheeled vehicle. The hitch is mounted relatively permanently to the seat post of the towing cycle but is free to swivel around said seat post as the trailer tracks around curves. The frame of the trailer to be towed has a frame the front reach of which consists of transversely disposed rounded bar or tubing. The essential universal-joint connection that makes a one-wheeled trailer feasible is completed by this rounded front reach of the frame captured rotatably within a horizontally disposed, rearward-facing slot in the hitch block. The capture is completed by means of a vertical, quickly removable pin preferably containing a spring-ball plunger. The pin is inserted behind said bar or tubing.
