Abstract

A rotation damper, particularly for damping the rotary movement of a belt retractor shaft of a vehicle safety belt, has a housing which delimits a working space filled with a damping medium, and an element which is rotatable relative to the housing. Several pins serving as resistance elements, which extend into the working space, are provided on the element.
