Claim Text:
1. A vehicle door latch system comprising: a latch positioned in a door to engage with a striker positioned in a vehicle body; a ratchet that engages with the latch to hold the door closed and disengages from the latch to enable the door to open; an electric drive mechanism that supplies power to move the ratchet from an engagement position where the ratchet engages with the latch to a release position where the ratchet disengages from the latch; a door-cooperating lever that is capable of moving from a neutral position in a releasing direction for disengaging the ratchet from the latch to enable the door to open, owing to movement of the door on the way of the door from an open position to a closed position and/or from the closed position to the open position; a release-canceling mechanism that is capable of switching a motion-transmitting path for transmitting power of the electric drive mechanism to the ratchet, from a connecting state where the motion transmitting path is connected, to a cut-off state where the motion transmitting path is cut off, by moving the door-cooperating lever from the neutral position in the releasing direction; and a contact pin, wherein the door-cooperating lever is positioned in one of the door and the vehicle body and the contact pin is positioned in the other of the door and the vehicle body, the door moving in a closing and/or opening direction and reaching to a certain position to allow the door-cooperating lever to come in contact with the contact pin, whereby the door-cooperating lever moves from the neutral position in the releasing direction and returning to the neutral position after it passes the certain position.
