Abstract

A torsional vibration damping arrangement for a drivetrain of a vehicle includes a carrier arrangement that is rotatable around an axis of rotation, a deflection mass movable in a circumferential direction relative to the carrier arrangement, and at least one radially extending, elastically deformable restoring element by which the carrier arrangement and the deflection mass are coupled to be rotatable relative to one another. A supporting element is associated with the restoring element and movable radially relative to the restoring element by which the restoring element is supported in circumferential direction with respect to the carrier arrangement at a radial position of the supporting element. A stiffness of the coupling between the carrier arrangement and the deflection mass which is brought about in circumferential direction by the restoring element has an abrupt course at least one radial position of the supporting element.
