Abstract

A motor-vehicle door latch has a housing adapted to be mounted in a motor-vehicle door having an inner wall, an opening lever displaceable into an actuated position for unlatching the door, an inside door handle, and a child-safety button on the inner door wall displaceable between an actuated position and an unactuated position. A child-safety lever on the housing is displaceable between a child-safety on position and a child-safety off position and a child-safety actuating element connected to the button and to the lever is displaced by the button on displacement of the button between its actuated and unactuated positions between a pair of end positions corresponding to the on and off positions of the child-safety lever. An actuating assembly connected to the child-safety actuating element and connected between the inside door handle and the opening lever displaces the opening lever into the actuated position on operation of the inside door handle when the child-safety lever is in its off position and decouples the opening lever from the opening lever when the child-safety lever is in its on position.
