Abstract
A rotational vibration damper, especially for arrangement in a drive train of a motor vehicle driven by an internal combustion engine, comprises first and second damping components that are rotatable together as well as relative to each other around a common rotational axis. The first and second damping components are connected to each other for rotational force transmission by a coupling mass arrangement. The coupling mass arrangement is connected to the first damping component so as to be pivotable about a pivot axis that is offset substantially axis-parallel to the center of gravity of the coupling mass arrangement and to the rotational axis. The coupling mass arrangement has two contact surface regions arranged at a distance from each other in the circumferential direction relative to the pivot axis and face away from each other. The second damping component has two counter-contact surface regions arranged at a distance from each other in the circumferential direction relative to the rotational axis and face each other. The two contact regions respectively contact the two counter-contact regions for rotational force transmission between the coupling mass arrangement and the second damping component.
