Rotation damper

A rotation damper for damping the movement of a component, comprising a transmission element which is couplable to the component in such a manner that said transmission element is rotated during a movement of the component, and comprising a rotatingly mounted rotor and also braking means which brake a rotational movement of the rotor, furthermore comprising coupling means which couple the transmission element and the rotor for conjoint rotation in a first direction of rotation of the transmission element and decouple same in a second, opposite direction of rotation, wherein the coupling means comprise a support element on which at least one engagement element is mounted so as to be pivotable between an engagement position, in which the at least one engagement element is in engagement with an engagement structure of the rotor, the engagement structure being arranged radially on the outer side with respect to the at least one engagement element, and a release position, in which the at least one engagement element is not in engagement with the engagement structure of the rotor, wherein the at least one engagement element has at least one coupling portion, and wherein the transmission element has at least one coupling portion which is in engagement with the at least one coupling portion of the engagement element, wherein the coupling portions of the transmission element and of the at least one engagement element are formed in a complementary manner with respect to each other.
