Abstract: A locking device for locking electrical plugs in sockets has a rotational track element which can be driven by a motor and on which a guide track is provided around the axis of rotation thereof, said guide track being provided with a plurality of track sections that have different pitches. A sliding element has a track engagement part that engages in the guide track and that can be displaced parallel to the axis of rotation of the rotational track element by rotation of the rotational track element.

Abstract: The invention relates to a locking system for a plug coupling device and to a plug coupling device having a housing in which the locking system according to the invention is arranged. A plug having a projection, which may for example be a guide pin of a commercially available safety plug, can be coupled to the plug coupling device by means of the locking system according to the invention, wherein a locking device in the form of a slider engages behind the projections of the plug such that the plug coupled to the plug coupling device cannot be removed from the plug coupling device. In addition, the locking device being in the locking position prevents an unauthorized insertion of a plug into the plug coupling device.

Abstract: In a closure for closing the orifice (13) of a neck (12), in particular the orifice of a fuel filler neck for automotive vehicles, a spring mechanism is provided which takes the form of a tightening device for drawing the closure part (14) automatically into its final closed position. The movement of the closure part (14) is controlled by a first guide slot (19). The operating lever (35), by means of which the closure part is moved, is furthermore hinged to the closure part (14) by means of a second guide slot (39), which, when an opening force is introduced via the closure part (14), blocks the movement of the closure part (14) from its closed position in the opening direction so that the closure part (14) cannot be manually opened from outside.

Abstract: In a method for activating a motor vehicle closure and in a closure device for motor vehicles a sensor device is activated by switching on an activation device and comprises a proximity sensor arranged in the vicinity of the closure part. The activated sensor device transmits an opening signal to the drive device to open the closure part when an approaching person and/or an approaching object comes within a predetermined distance from the proximity sensor, whereupon the drive device opens the motor vehicle closure.

Abstract: A closure device for an electrical plug-in coupling arranged on a motor vehicle or a charging station. A locking arrangement is provided for locking the plug coupled to the plug-in coupling. The locking arrangement can be operated via a gear mechanism between the drive motor and the closure flap. The locking arrangement has a locking element which, when the closure flap is transferred from an intermediate open position, in which the plug can be coupled to the plug-in coupling, into the final open position, can be brought into a locked position which prevents the removal of the plug from the plug-in coupling.

Abstract: A fuel tank closure for closing off a filling channel has a closure part that can be moved between a closed position in which an opening of the filling channel is tightly sealed, and an open position, in which the filling channel is released, in order for a fuel tank to be filled. The closure part is driven by a drive unit that has a motor.

Abstract: In a closure for closing the orifice 6 of a socket-piece 4, with a closure part 5, which is able to depart from its closure seat by swiveling, there is provided a constraining guide for the closure part 5, by means of which the closure part 5 is so guided that during the opening procedure it lifts from its closure seat in an approximately axial direction and, continuing on from this axial movement, is tilted away laterally to the outer wall. The constraining guide can consist of a coulisse guide or a lever-bar.

Abstract: A self-closing fuel tank closing device mountable on a fuel tank filler pipe includes a filler cap which is tensioned in the direction of a sealing seat and is rotatable in the direction of the interior of the filler pipe. The filler cap is carried by a swivel arm supported at one end thereof. In order to achieve a small construction and degressive torque characteristics on opening the filler cap, it is provided that the free end of the swivel arm is supported on a supporting surface which runs approximately perpendicular to the longitudinal axis of the fuel tank closing device. The device further includes a clamping device which pretensions the filler cap in the direction of the sealing seat and is mounted on the swivel arm in the region between the free end and the filler cap.
