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.

Device for damping torsional vibrations in the body of a convertible vehicle, comprising:
- a damper being mounted elastically on a frame of a windshield by slide bearings and mounted to be freely oscillating at a distance from the frame in the transverse direction of the vehicle, the damper having a frequency equal to the torsional natural frequency of the vehicle in the vicinity of the frame, and the bearings having a sliding resistance determined by their geometry, wherein the slide bearings include at least one central slide bearing on a frame element, with a damping weight having a leaf spring element mounted at each end and mounted to abut the frame element to permit movement of the damping weight in the transverse direction.
