  • Patent number: 8967680
    Abstract: In a planetary gear mechanism of a vehicle door closer device, a planetary gear meshes with a sun gear and a ring gear. When the ring gear turns in one direction, the planetary gear orbits while it turns on its own axis. A closing lever is pivoted on the planetary gear and turns with orbiting of the planetary gear to move the latch to a full-latch position to enable the door to close. When the ring gear turns in the other direction, the planetary gear turns on its own axis and the sun gear turns to allow the ratchet to release from the latch to to enable the door to open. The planetary gear mechanism slows down a motor and a motion is transmitted to the ratchet to enable the ratchet to release from the latch. When the motor stops, the motion is disconnected to enable the ratchet to return to engagement with the latch.

  • Patent number: 8939511
    Abstract: A first and a second surface of a latch for a seat permit sliding passage of the latch relative to a front leg of a striker, upon contact of the front leg with either of the first and second surfaces. A third surface in a containing space of the latch stops the latch by contacting the front leg. The third surface is arranged such that a rear leg of the striker is brought in alignment with a lock groove of the latch upon contact of the front leg with the third surface. The latch can be guided along the second surface when the second surface contacts the front leg, so that the second surface slides on and past the front leg. By continuously unfolding the seat back upwards until the third surface contacts the front leg, the seat back can be set to a design reference position.

  • Publication number: 20140312632
    Abstract: In a vehicle door latch device, a first outside lever is pivotally mounted via a pivot shaft, and second outside lever is connected to an outside handle on an outer panel of a door via a motion-transmitting member to move toward the inside of a vehicle. Usually, turning of the second outside lever for disengaging a latch from a striker is transmitted to the first outside lever. If the second outside lever is impacted by an external force, the outer panel is deformed to move the second outside lever inward of the vehicle with respect to the first outside lever. But release turning of the second outside lever cannot be transmitted to the first outside lever. Even if the door is deformed by the external force, the door is still closed.
