  • Patent number: 11594841
    Abstract: A locking device for an electrical charging device of a motor vehicle, in particular an electric or hybrid vehicle. The locking device is equipped with a movable bolt element, which is provided for releasably locking a charging plug in a charging socket of the electrical charging device. In addition, the movable bolt element can be moved at least into the positions “unlocked” and “locked.” Furthermore, a motor-driven drive is realized, which is provided for moving the bolt element. According to the invention, the bolt element can be moved into a third “self-locked” position beyond the “locked” position, which can be reached by means of the drive and in which unlocking is impossible without the drive.

  • Patent number: 10829963
    Abstract: The invention relates to an actuating device for opening a door or flap, comprising a movably supported inertial mass (7, 9) for avoiding unintentional opening of the door or flap in the event that a specified acceleration is exceeded. Levers are provided for moving the inertial mass (7, 9). When the inertial mass (7, 9) is moved out of an initial position of the inertial mass, the lever ratios change in such a way that the force progression is thereby promoted. In the event of a crash, the opening of a door or flap is avoided by means of the actuating device. The actuating device can nevertheless be actuated relatively comfortably with low expenditure of energy.

  • Patent number: 10829968
    Abstract: The invention relates to a motor-vehicle lock, in particular a motor-vehicle door lock. In order to provide a reliable assembly and a reliable operation for said lock, the drive housing 6 of the servo closing function 2 is designed to function simultaneously as a Bowden cable bearing 8 and as a receiving chamber or shaft 14 for the micro-switch 15. The drive housing 6 has a robust, compact design and allows the micro-switch 15 to be sited securely in the drive housing 6 always in the same place. This also remains the case as the securing cover 10 is fixed in the drive housing 6 by means of a clip 11.
