ABSTRACT:
A vehicle door locking system uses a simple latch mechanism (10) without internal locking means connected to an external door handle (28) through a collapsible bellows (32). A solenoid controlled valve (44), when open, vents the bellows to atmosphere, allowing the bellows to collapse and transmit no movement from the door handle to the latch mechanism or, when closed, presents collapse of the bellows, which then transmits movement of the door handle to the latch mechanism.
