Abstract
A rotary damper with a housing, with a rotor rotatably mounted in a closed chamber of the housing and with a viscous medium disposed within the chamber, wherein the rotor is so formed and so cooperates with the wall of the chamber that with a relative rotation of the housing and the rotor, a braking effect is produced by the medium, and wherein at least two rotor elements are provided which are arranged coaxially, preferably commonly in the chamber, and the neighboring rotor elements are coupled such that they are freely rotatable relative to one another over a limited rotational angle.
