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.
Claims20
A motor vehicle latch made by the process comprising:
- providing a stamped catch having a first free end, a first stamped side on the first free end, the first stamped side having stamping contours, and a first side surface adjacent to and perpendicular to the first stamped side, wherein the stamped catch is a first locking component and wherein the stamped catch defines a first ratchet surface on the first free end;
- providing a stamped pawl which locks the stamped catch in the closed state, the stamped pawl having a second free end, a second stamped side on the second free end, the second stamped side having stamping contours and a second side surface adjacent to and perpendicular to the second stamped side, wherein the stamped pawl is a second locking component and wherein the stamped pawl defines a second ratchet surface on the second free end;
- and
- bending one of the first or second locking components at its respective first or second free end thereby positioning the first or second side surface as the first or second ratchet surface that abuts the first or second ratchet surface of the other locking component.
