Abstract:
A module for producing a force hysteresis during pivoting of a rotary element comprising:(a) a housing; (b) a rotary element mounted on the housing for rotation about a rotary spindle between starting and operating positions, the rotatable element including a portion located within the housing; (c) a stationary friction surface formed on the inside of the housing, which surface curves with a changing radius about the rotary spindle; (d) at least one bore in the portion of the rotary element located within the housing, which bore is open in the direction facing the stationery friction surface; and (e) a spring biased friction element located in the at least one bore pressing against the curved, stationary friction surface, wherein in all the angled positions of the rotary element relative to the housing, the reaction force of the spring biased friction element subjects the rotary element to a restoring moment about the rotary spindle.
