Abstract
An irreversible adjustment mechanism comprising a pivoting lever resiliently assisted to a neutral position, an intermediate pivoting part connected to the lever by a driving stage adapted to move the intermediate part only when the lever moves away from its neutral position, a fixed collar, an output part delimiting with the collar wedge-shaped hollow spaces directed in opposite directions, and a locking stage ensuring an irreversible transmission between the intermediate part and the output part with a certain angular play of the intermediate part. The intermediate part is braked with a braking torque sufficient to lock the intermediate part in each return movement of the input part to its neutral position.
