Abstract

The invention relates to a method for producing motor vehicle door locks with the locking parts: a rotary latch and a pawl. Said latch and the pawl are stamped from rolled sheet metal defining vertical or approximately vertical edges with corresponding latch surfaces on the rotary latch and the pawl, and subsequently are provided with a covering while maintaining the catch surfaces. After stamping, the locking parts are bent in the region of the main latch and/or another latch resulting in the formation a contour which is void of stamped channels, and are then inserted into the lock housing box.
