    Abstract: A device for motorized opening and closing of pivotable body panels of motor vehicles, especially the rear trunk lid or rear hatch and/or the hood of automobiles, has a motor-actuated lever system engaging in an articulated manner, on the one hand, with the body panel, and on the other hand, with the body. The body end of the lever system is articulated at a slide block guided slidingly in a guide track. The slide block is operatively connected to a driver that is secured to a control cable. The ends of the control cable can be wound onto or off a common cable pulley actuated by an electric motor.

    Abstract: A safety device for preventing accidental unrolling of a rolling shutter or overhead door comprising a cogwheel which has uniformly distributed on the circumference opening outward for containing radially movable tumblers, a cage which surrounds the cogwheel that contains an abutment in the form of a recess for the tumblers which are raised by the action of centrifugal force. Upon reaching a predetermined rotational speed, the tumblers engage an abutment in the cage and the cage acting as a brake is then driven by the cogwheel and slowed down by friction.
