Abstract

A gearing mechanism includes a housing component and a shaft mounted in the housing component. The shaft is driven rotating relative to the housing component with regard to a rotation axis in a first rotation direction and in a second rotation direction opposite the first rotation direction. There is also a wrap element that wraps the shaft multiple times. A first end of the wrap element is fastened to the housing component. It is also possible that an inward oriented friction surface is provided and that the wrap element is arranged within the inward oriented friction surface at least in sections in order to interact with the friction surface. In an alternative embodiment, a brake element is provided, the shaft comprises a brake element receptacle that at least partially accommodates the brake element and a contact surface is allocated to the brake element for interacting with the brake element.
