ABSTRACT:
A vehicle door lock system includes interior and exterior handle assemblies that are accessible, respectively, from interior and exterior sides of a vehicle door on which the door lock system is mounted. The system includes a plurality of rotary latches that are configured to releasably engage door-frame-mounted strikers to "latch" and "unlatch" the door, and a latch interconnection linkage for effecting concurrent unlatching of the rotary latches. The door is "locked" and "unlocked" by selectively enabling and disabling at least one driving connection between at least one of the handle assemblies and separate latch release arms that are arranged to operate a selected one of the rotary latches. In preferred practice, locking and unlocking of the door are effected either by operating an exterior key cylinder, or by operating an interior sill button.
