  • Publication number: 20230272657
    Abstract: A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

  • Publication number: 20220049534
    Abstract: A drive assembly for a flap of a motor vehicle includes at least one motor drive and at least one gas pressure element having a cylinder and a piston. The piston divides the cylinder interior into two partial spaces and has a passage arrangement, through which a balancing flow between the two partial spaces arises when the piston moves. The gas pressure element has a first drive connection point connected to the cylinder and a second drive connection point connected to the piston. A switchable valve assembly is associated with the piston and can be brought into a closed state, in which the valve assembly at least partially closes the passage arrangement, and it has an open state, in which the valve assembly opens the passage arrangement. The passage arrangement automatically switches into the closed state in the event of a balancing flow that exceeds a predefined switching flow.

  • Patent number: 9732544
    Abstract: The invention relates to a lock for a door, comprising a catch and a pawl. The catch can be in an open or closed position. The catch may be brought into holding engagement with a lock striker. The pawl may be brought into an engagement position. The pawl may be deflected into a release position, to release the catch. A pawl actuation lever can deflect the pawl into the release position. A switchable coupling arrangement is provided between the pawl actuation lever and the pawl. The switchable coupling arrangement may be brought into a closing and an opening state. When the actuation movement of the pawl actuation lever surpasses a threshold, an inertial characteristic of the lock causes the switchable coupling arrangement to switch into the opening state such that the pawl actuation lever runs without deflecting the pawl into its release state.
