Description

The present invention relates to a locking element for a locking mechanism of a motor vehicle lock according to the preamble of claim 1, a motor vehicle lock according to the preamble of claim 9, a modular system for a motor vehicle lock according to claim 17, a motor vehicle lock arrangement according to claim 18, and a method for manufacturing motor vehicle locks according to the preamble of claim 21. Various motor vehicle locks with locking components are known from the prior art. The motor vehicle lock in question is applicable to all types of locking elements of a motor vehicle. The locking element can, in principle, be pivotable and/or longitudinally displaceable on the motor vehicle. Furthermore, it can, in particular, be pivotable primarily about a horizontal or primarily about a vertical pivot axis. Such locking elements include, for example, side doors, especially sliding doors, tailgates, trunk lids, bonnets, cargo floor or the like of a motor vehicle. In the EP 3 688 257 A1 For example, a vehicle lock is described which has a latch and a locking pawl system with a primary locking pawl and a secondary locking pawl as locking components. The latch can be moved into a main locking position and, if applicable, a pre-locking position. Corresponding to these two locking positions, a pre-latch and a main latch are provided on the latch of the vehicle lock. Although the doctrine implies EP 3 688 257 A1 The fact that the pre-locking position cannot be realized, but whether and how the locking components – latch, primary locking pawl, and secondary locking pawl – should then be physically designed and arranged relative to each other, is in the EP 3 688 257 A1 not described. Starting with a motor vehicle lock - like the one in the EP 3 688 257 A1 The described vehicle lock has now revealed a need for a cost-effective and simply constructed vehicle lock. The invention is based on the problem of creating the possibility of providing a cost-effective and simply constructed motor vehicle lock. The above problem is solved in a locking component by the features of the characterizing part of claim 1. The fundamental consideration is to use a locking component for a motor vehicle lock, particularly an already developed motor vehicle lock with a pre-locking position and a main locking position, with a first and a second locking contour, also for a motor vehicle lock where one locking position, or one fewer locking position, is sufficient. The basic idea here is to simply deactivate the second locking contour of the locking component. This can be achieved by making the second locking contour inaccessible to another locking component. The idea is to further develop and physically design the vehicle lock and the locking mechanism in such a way that a simpler locking mechanism for another vehicle lock can be easily derived from a vehicle lock with a multi-position locking mechanism, in particular a two-latch locking mechanism, by deactivating one of the locking positions or latches. This can, for example, save on development and production costs for an additional lock or vehicle lock. In particular, if a multi-position lock is already designed in such a way that one fewer locking position can be implemented, development costs for the additional lock or vehicle lock can be reduced, and economies of scale in the production of both vehicle locks can be achieved through the use of identical parts. In particular, by simply exchanging a locking component, which is installed on one side with the second locking contour activated and on the other side with the second locking contour deactivated, especially in the same motor vehicle lock production line, two different motor vehicle locks for different requirements can be produced in a simple and particularly cost-effective manner. Specifically, for a locking element for locking a motor vehicle lock, in particular for a lock latch, it is proposed to provide a first locking contour for locking the motor vehicle lock in a first locking state, in particular the main locking state, and furthermore to provide a second locking contour for locking the motor vehicle lock in a further locking state, in particular the pre-locking state, which is deactivated, wherein the deactivation means that the second locking contour is not accessible to another locking element for locking the motor vehicle lock. A preferred embodiment of the locking element is described in claim 2, which describes a particularly preferred design of the locking element. A particularly simple and cost-effective method of adapting the locking element is described. The further development according to claim 3 enables a particularly robust design of the locking mechanism and the absorption of high forces, especially in the event of a crash. Claims 4 to 7 describe particularly preferred embodiments of the locking element which allow a particularly simple and advantageous construction of the pawl system for a locking mechanis
