ABSTRACT:
A rotational restriction lock is formed as a one-piece restricting element which is resiliently mounted on a rotor shaft and has a hub which is always resiliently driven in rotation by the rotor throughout a small angle, spring arms which transmit the rotary movement, and movable rotation restricting elements to which the rotary movement is transmitted and the ends of which prevent the rotor from rotation in an undesired direction, but allow the rotation of the rotor in a desired direction. Adjustable abutments are provided for selecting a permissible angle of rotation of the hub.
