Multi-pull latch and lock systems for compartment closure assemblies of motor vehicles

摘要

Disclosed are lock mechanisms for latch assemblies of vehicle compartment hoods, methods for making or using such lock mechanisms, and motor vehicles equipped with a multi-pull latch and lock system for releasably locking a hood assembly. A lock mechanism includes a gear that couples a closure latch to a latch release mechanism. The gear moves between a latched position, whereat the closure latch secures the closure in a closed position, and an unlatched position, whereat the gear transfers activation forces from the release mechanism to disengage the closure latch from the closure. A pawl is movable between a locked position, whereat the pawl engages and locks the gear in the latched position, and an unlocked position, whereat the pawl disengages the gear. An actuator is operatively engaged with a vehicle door to automatically move the pawl to the unlocked position responsive to movement of the door to an open position.
