Abstract
A latch member or rotor is rotatably mounted in a main body or frame, attached to a vehicle door, for engaging a striker affixed to the vehicle body. Also mounted in the main body, in coplanar relation to the latch member, is a ratchet engageable with the latter to inhibit its motion in a direction to disengage the striker. The main body has an upstanding bracket on which three levers are mounted for pivotal motion about a common axis, in planes perpendicular to the plane of the latch member and the ratchet. The three levers are: (1) an actuating lever acting directly on the ratchet to cause the same to disengage the latch member and hence to unlatch the door; (2) an outside release lever linked to an outside door handle; and (3) an inside release lever linked to an inside door handle. These levers are interrelated in such a manner that the latch member releases the striker upon actuation of either the outside or the inside door handle. The invention further comprises, as incidental features, a locking mechanism for making the actuating lever unresponsive to the actuation of both outside and inside door handles, and a childproofing mechanism for making the actuating lever unrespons…
