  • Selective one-motion door opening mechanism for door latch of vehicle
    Patent number: 7293806
    Abstract: The present selective type one-motion door opening mechanism comprises a ratchet lever (32) for opening a vehicle door, an open lever (22) displaceable by an outside open handle (25), a lock lever (23) displaceable between an unlocked position (U) in which a displacement of the open lever is transmitted to the ratchet lever and an locked position (L) in which the displacement of the open lever is not transmitted to the ratchet lever, a sub-lever (35) being rotated by an inside open handle (19), and a selector pin (41) displaceable between an effective position (X) and to a ineffective position (Y). The rotation of the ratchet lever returns the lock lever to the unlocked position. The selector pin at the effective position transmits the rotation of the sub-lever to the ratchet lever, and selector pin at the ineffective position transmits the rotation of the sub-lever to the open lever.
