Abstract
A vehicle door latch has a fork bolt lever that is latched by a detent lever. The detent lever is operated by an intermittent lever that is operated by a transfer lever that is actuated by inside and outside door handles via operating levers. The door latch includes with a locking lever that disconnects the door handles from the intermittent lever when it is in the locked position. The door latch also includes an interlock between the intermittent lever and the locking lever that is automatically engaged in response to the position of the detent so that the door latch cannot be locked when the fork bolt lever is in an unlatched position. Consequently the door latch can only be locked when the door is closed and the fork bolt lever is in a latched position. This prevents the driver from locking his or her keys in the vehicle.
