Abstract
In a device for damping torsional vibrations of the body of a convertible vehicle, an elastically mounted weight is used. The damper is mounted elastically on a frame of a windshield by slide bearings and at a distance from the frame, relatively free to vibrate in the transverse directions of the vehicle. The damper has a frequency equal to the torsional natural frequency of the vehicle in the area of the frame, with the bearings having a sliding resistance determined by their geometry. The damper is elastically mounted by at least one central slide bearing on the frame element, with the damping weight having a leaf spring element at each end and mounted to abut the frame element and to permit transverse movement of the damping weight.
