Embodiment Construction

[0066] figure 1 Shown is a locking mechanism part 1, a locking yoke for a motor vehicle lock, comprising a fork-shaped entry slot into which a not shown latch of the door or hatch enters when the door or hatch is locked.

[0067] The locking mechanism part 1 or locking fork comprises three stamped metal plates 3, 4, 5, wherein the lowermost stamped metal plate 3 and the middle stamped metal plate 4 are stamped metal plates 3, 4 of the type of the first stamped metal plate 3, 4 4. A stamped metal plate 5 of the type of a second stamped metal plate 5 is arranged thereon. The stamped metal sheets 3 , 4 , 5 are connected to one another in a non-detachable manner and are surrounded or overmolded by a housing 6 .

[0068] Since the lower two stamped metal plates 3, 4 have a greater stamped metal plate thickness than the upper stamped metal plate 5 and are additionally hardened, the locking fork can be produced with only three stamped metal plates 3, 4, 5, obtaining Particularly hi...

Abstract

The invention relates to a locking mechanism part for a motor vehicle lock, in particular a locking yoke, for holding and fixing a closing member in the closed position of a door or hatch of a motor vehicle, comprising at least a first stamped metal plate and a a second stamped metal sheet, wherein the stamped metal sheets are connected to one another in a non-detachable manner, and the first stamped metal sheet has a different stamped sheet metal material and / or a greater stamped sheet metal thickness than the second stamped metal sheet, In this case, the first stamped metal sheet and the second stamped metal sheet have at least partly or mostly the same outer contour and / or are arranged one above the other so that sections with the same outer contour are arranged flush with each other on the outside. The invention also relates to a production method. Locking mechanism components that are strong and long-lived but inexpensive to produce can be provided.

Description

technical field [0001] The invention relates to a locking mechanism component, in particular a locking yoke, for a motor vehicle lock according to the preamble of the main claim. The invention also relates to a method for manufacturing a locking mechanism component. Background technique [0002] Motor vehicle locks are used to temporarily lock doors or hatches in motor vehicles. [0003] A lock for a motor vehicle includes a locking mechanism having a rotatably mounted yoke for receiving a deadbolt. The locking mechanism also includes a locking pawl, through which the locking fork can be locked. [0004] The cleat of a motor vehicle lock typically includes a fork-shaped entry slot into which the latch of a door or hatch (such as a hood or deck lid) enters when the door or hatch is locked. The latch then turns the prongs from the open position to the closed position. If the locking fork has reached the closed position, it is locked to the pawl in this position. Then, the...
