Vehicle door latch

1. A method of preventing a detent lever of a vehicle door latch assembly from moving to a disengaged position when the detent lever has been moved to an engaged position by a remotely activated actuator, the method comprising:

pivotally securing a fork bolt to the vehicle door latch assembly for movement between an unlatched position where the fork bolt does not engage a striker and a latched position where the fork bolt engages the striker;

pivotally securing the detent lever to the vehicle door latch assembly for movement between the engaged position and the disengaged position wherein a contact surface of the detent lever engages a contact surface of the fork bolt when the detent lever is in the engaged position and the fork bolt is in the latched position;

preventing the detent lever from moving into the disengaged position from the engaged position until an inertia block out assembly of the vehicle door latch is moved from a blocking position to an unblocking position; and

moving the inertia block out assembly from a blocking position to an unblocking position, by a manual override mechanism, wherein the manual override mechanism must be actuated at least three consecutive times in order to move the inertia block out assembly from the blocking position to an unblocking position, wherein the detent lever is capable of being moved from the engaged position to the disengaged position when the inertia block out assembly is in the unblocking position.

2. The method as in claim 1 , wherein the inertia block out assembly further comprises:

a blocking member that is able to rotate in such a manner that a portion of the blocking member impedes rotation of the detent lever when the blocking member is in a blocking position, the blocking lever being in the blocking position when the inertia block out assembly is in the blocking position.

3. The method as in claim 2 , wherein the inertia block out assembly further comprises: a sliding rack having an integral cam driving feature that is configured to slidably engage a cam opening integrally formed in the blocking member and wherein movement of the cam driving feature in the cam opening causes movement of the blocking member between the blocking position and an unblocking position.

4. The method as in claim 3 , further comprising: an electromotive motor for driving a helical gear coupled to the sliding rack.

5. The method as in claim 1 , wherein the inertia block out assembly further comprises:

a blocking member that impedes rotation of the detent lever when the blocking member is in a blocking position, the blocking lever being in the blocking position when the inertia block out assembly is in the blocking position and wherein the blocking member has an internal threaded portion configured to interface and be driven by a power screw member coupled to motor.

6. The method as in claim 1 , wherein the inertia block out assembly further comprises:

a blocking member that is able to rotate in such a manner that a portion of the blocking member impedes rotation of the detent lever when the blocking member is in a blocking position, the blocking lever being in the blocking position when the inertia block out assembly is in the blocking position; and

a detent release lever configured to move the blocking member between the blocking position and an unblocking position, wherein the detent release lever is clutched to the blocking member by a decoupling device such that movement of the detent blocking member also decouples the detent release lever 6 from a release mechanism of the latch.

7. The method as in claim 6 , wherein the decoupling device further comprises: the detent release lever, a clutch lever, a return spring, and an input lever movably displaced by the release mechanism of the latch, wherein the detent release lever and the input lever are capable of independent movement unless they are coupled together via the clutch lever when the clutch lever is in an engaged position.
