Vehicle door latch mechanism
First Claim
1. Vehicle door latch mechanism including a main actuating lever operable by an exterior handle of the door and/or a remotely controlled power actuator in use to release the mechanism for opening the door, an inside release lever operable by an interior handle of the door in use;
- and a child safety facility having setting means inaccessible when the door is closed for selectively enabling and disabling drive connection of the inside release lever with the main actuating lever;
characterised in that said facility includes a drive dog slidingly engaged with an arm of one of said levers for movement longitudinally thereof between a driven position at which it co-acts with an arm of the other of said levers to transmit drive from the inside release lever to the main actuating lever and a disabling portion at which it is clear of the latter arm, and a setting element linked to the dog for effecting said movement and operatively positioned so as to be accessible only when the door is open, wherein the dog comprises a slide block carried on an arm of the main actuating lever, and the inside release lever is pivoted for movement in a plane normal to the plane of the latter arm.

Abstract
Vehicle door latch mechanism with child safety facility includes a base plate 12 having a throat 14 which receives a striker with which the latch engages. A main actuating lever 16 is operable by an exterior door handle and/or power actuator to release the latch and has an arm 22 carrying a longitudinally slidable drive dog 24. A release lever 18 operable only by an inside door handle is pivoted in a plane normal to the plane of arm 22. A rotatable button 26 in throat 14 so as to be accessible only when the door is open has crank connection to dog 24 to shift it between a drive position at which the levers coact and a disabling position at which movement of release lever 18 will not drive lever 16.
