  • Patent number: 10988075
    Abstract: A vehicle lighting device includes at least one headlight, a position and/or acceleration sensor, and a control unit for adjusting a light/dark boundary of the headlight. Pitch movements of the vehicle can be detected by the position and/or acceleration sensor, and a change in the light/dark boundary due to the respective pitch movement can be compensated for by the control unit. The position and/or acceleration sensor and the control unit are arranged in the headlight or directly on the headlight.

  • Patent number: 8146392
    Abstract: A latch has a housing and a dead bolt shiftable on the housing between extended and retracted positions. A latch nut is rotatable on the housing and connectable to door handles and carries actuating and panic levers. An actuating element is connected between the dead bolt and the actuating lever, and a panic element is connected between the panic lever and a locking pawl and is movable between an unactuated position and an actuated position to shift the locking pawl into an unlocked position. A key cylinder on the housing has a movable actuating lug movable between a locking end positing and a freeing end position. A pivotal locking pawl is shiftable by movement the actuating lug of the key cylinder into a locked position blocking movement of the actuating element and holding the dead bolt in the extended position and an unlocked position freeing the bolt and actuating element.

  • Publication number: 20080156049
    Abstract: A latch for a door or window latch has a housing, a spring bolt and a dead bolt shiftable on the housing between respective extended and retracted positions. A key cylinder on the housing can shift a pivotal locking pawl between a locked position retaining the dead bolt in the respective extended position and an unlocked position permitting the dead bolt to move between the respective extended and retracted positions. A latch nut pivoted on the housing is connected to inside and outside door handles and carries an actuating lever and a panic lever. An actuating element is connected between the dead bolt and the actuating lever, and a panic element is connected between the panic lever and the locking pawl and is and movable between an unactuated position and an actuated position to shift the locking pawl into the unlocked position.
