METHOD FOR PRODUCING MOTOR VEHICLE DOOR LOCKS WITH A ROLLING SURFACE AS A LOCKING PART CONTOUR

摘要

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 whilst 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.

1. Procedure to produce the locking mechanisms catch and pawl of a motor vehicle latch, whereby the catch and pawl are stamped out of rolled sheet metal with simulatingly vertical or virtually vertical edges with corresponding ratchet surfaces for the locking mechanism and are then equipped with a casing, with the ratchet surfaces being kept free, characterised by the fact that the locking mechanisms are bent in the area of the main ratchet and/or another latch after stamping, giving a stamping groove-free contour and are then used in the latch casing box.
