Abstract

A locking arrangement for a motor vehicle door in which a lock housing with a rotary catch acting on a locking bolt on the side of the body, a spring-loaded locking latch, a knee lever arrangement engaging at the rotary catch and at the housing which is formed by two lever members connected in a dead-center joint, and an actuating mechanism is provided, whereby two end positions of the dead-center joint which are coordinated to the locking, respectively, the open position of the rotary catch, are determined by control abutments, and whereby a torque is to be introduced into the rotary catch by means of the actuating mechanism by way of the knee lever, by means of which the door is adapted to be transferred into the locked position against the force of an elastically deformed door seal. This lock arrangement is characterized in that the closing force is to be introduced manually into the actuating mechanism by a door handle at which a return device is effective.
