Abstract
A vehicle door latch system configured to temporarily prevent door latch mechanisms from unlatching during a predetermined event is provided. The vehicle door latch system includes a forkbolt pivotally mounted to a housing portion of the vehicle door latch. The forkbolt is capable of moving between a latching position and an unlatching position. The door latch system also includes a block out mechanism configured for movement between a blocking position and an unblocking position. The block out mechanism is configured to prevent the forkbolt from moving from the latching position to the unlatching position when the block out mechanism is in the blocking position. A biasing member biases the block out mechanism into the unblocking position. The door latch system also includes an activation mechanism for moving the block out mechanism to the blocking position when the activation mechanism is activated for a predetermined time period to overcome the biasing member and after the predetermined time period, the block out mechanism moves to the unblocking position by the biasing member.
