Abstract
The module ( ) serves for producing a force hysteresis during pivoting of a rotary element ( ) which is mounted rotatably in a housing ( ) and on which there is secured at least one spring element ( ), of which the free end slides, via a friction element ( ), on a stationary friction surface ( ). In order for it not to be necessary to rely on separate restoring mechanisms, it is proposed that, in all the angled positions of the rotary element ( ) relative to the housing ( ), the reaction force of the spring element ( ) subjects the rotary element ( ) to a restoring moment about the rotary spindle ( ). Such a module ( ), with a compact construction, makes it possible, with the aid of a spring element ( ), to produce both the restoring forces and the frictional forces necessary for the hysteresis.
