  • Publication number: 20210156175
    Abstract: A vehicle door latch apparatus has latch mechanism, powered release means, manual release means and lock mechanism that is switched between a locked state and an unlocked state. Powered release means has cam wheel that is rotated in normal and in reverse rotational directions from a reference position by motor power. When cam wheel is rotated in the normal rotational direction from the reference position, latch mechanism is released while lock mechanism is held in the locked state When cam wheel is rotated in the reverse rotational direction from the reference position, cam wheel switches lock mechanism to the unlocked state. Cam wheel returns lock mechanism to the locked state when cam wheel is rotated in the normal rotational direction back to the reference position in the unlocked state.
