Description

[0001] 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.

[0002] 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.

[0003] Such locking elements include, for example, side doors, especially sliding doors, tailgates, trunk lids, bonnets, cargo floor or the like of a motor vehicle.

[0004] For example, EP 3 688 257 A1 describes a motor vehicle lock which has a latch and a pawl system with a primary pawl and a secondary 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 motor vehicle lock.

[0005] Although the teaching of EP 3 688 257 A1 implies that the pre-locking position may not be realized, it is not described in EP 3 688 257 A1 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.

[0006] Starting from a motor vehicle lock - such as the motor vehicle lock described in EP 3 688 257 A1 - it has now become apparent that there is a need for a cost-effective and simply constructed motor vehicle lock.

[0007] The invention is based on the problem of creating the possibility of providing a cost-effective and simply constructed motor vehicle lock.

[0008] The above problem is solved in a locking component by the features of the characterizing part of claim 1.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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 mechanism with such a locking element.

[0017] According to a further preferred embodiment according to claim 8, the locking part can have an attack contour for a closing aid.

[0018] According to a further teaching as per claim 9, which has independent significance, a motor vehicle lock is claimed.

[0019] It is essential that the lock latch is designed as a locking component in accordance with the described type and / or that the vehicle lock does not assume any further locking state when the lock latch is adjusted from the open position to the closed position and that the locking pawl system is designed to realize an additional locking position for a further locking state of the vehicle lock, in particular a pre-locking state, by providing a second locking contour on the lock latch.

[0020] The underlying idea is to develop and physically design the vehicle lock and / or 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 and / or by replacing a locking mechanism component.

[0021] 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, it is possible to reduce development costs for the additional lock or vehicle lock and to leverage economies of scale in the production of both vehicle locks by using identical parts.

[0022] In particular, by simply exchanging a locking component, which is installed on the one hand with an activated second locking contour and on the other hand without a second locking contour or with a deactivated second locking contour, 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.

[0023] Reference may be made to all statements concerning the proposed section of the barrier.

[0024] According to the preferred embodiment of claim 10, the locking pawl system can be designed as a single locking pawl system or as a double locking pawl system, the latter of which can reduce the forces required to open the motor vehicle lock.

[0025] According to the preferred embodiment of claim 11, the lock latch and locking pawl system are arranged and designed in such a way that, upon activation and access to the second locking contour, a further locking state can be produced in the manner described.

[0026] Claims 12 and 13 describe particularly advantageous and simple mechanisms for opening the motor vehicle lock.

[0027] Claim 14 describes a memory function which ensures particularly secure opening of the motor vehicle lock.

[0028] Claim 15 describes preferred embodiments relating to closing the motor vehicle lock and interrupting the closing process by means of a closing aid.

[0029] Claim 16 describes preferred embodiments for the sensorial detection of the states of the motor vehicle lock.

[0030] According to a further teaching as claimed in claim 17, which is also of independent significance, a modular system for a motor vehicle lock is claimed. The modular system comprises a motor vehicle lock of the type described and additionally a further lock latch. The further lock latch is designed to be inserted into the motor vehicle lock in place of the lock latch. It has a first locking contour and a second locking contour. Furthermore, the further lock latch of the proposed modular system is designed such that, when inserted into the motor vehicle lock in place of the lock latch, the first locking contour of the further lock latch is accessible to the locking pawl system for generating the main locking state, and the second locking contour of the further lock latch is accessible to the locking pawl system for generating the further locking state as a preliminary locking state.

[0031] Reference may be made to all explanations regarding the proposed locking component and the proposed vehicle lock, as well as the advantages described therein. These also apply analogously to the modular system.

[0032] According to a further teaching according to claim 18, which also has independent significance, a motor vehicle lock arrangement is claimed with a first motor vehicle lock of the described type and a second motor vehicle lock, wherein the second motor vehicle lock has a lock latch with a first locking contour for locking the motor vehicle lock with a locking pawl system in a first locking state, in particular main locking state, and with a second locking contour for locking the motor vehicle lock with the locking pawl system in a further locking state, in particular pre-locking state, which is activated and accessible.

[0033] Reference may be made to all explanations regarding the proposed locking component and vehicle lock, as well as the proposed modular system and the advantages described therein. These also apply analogously to the vehicle lock arrangement.

[0034] According to the preferred embodiment of claim 19, the lock latches between the first and / or second motor vehicle lock are interchangeable in the manner described.

[0035] According to a further teaching as claimed in claim 21, which also has independent significance, a method for manufacturing motor vehicle locks is claimed.

[0036] It is essential that in a production line for the manufacture of motor vehicle locks the first motor vehicle lock is assembled and in the same production line the second motor vehicle lock is assembled, preferably that at the same station of the production line for the manufacture of the first motor vehicle lock or the second motor vehicle lock either the lock latch of the first motor vehicle lock or the lock latch of the second motor vehicle lock is installed, further preferably that the lock latch of the first motor vehicle lock and the lock latch of the second motor vehicle lock are installed in the respective motor vehicle lock by the same handling unit.

[0037] Reference may be made to all statements concerning the proposed locking component, vehicle lock, modular system and the proposed vehicle lock arrangement.

[0038] The invention will now be explained in more detail with reference to a drawing that merely illustrates exemplary embodiments. The drawing shows Fig. 1 in a) a motor vehicle with proposed motor vehicle locks and b) a proposed locking element in the form of a lock latch, Fig. 2 the locking element of a proposed motor vehicle lock in a) a closed state and in b) an open state, Fig. 3 the locking elements of the motor vehicle locks of a proposed motor vehicle lock arrangement, wherein a) the locking element of a proposed motor vehicle lock with a proposed locking element and b) the locking element of the second motor vehicle lock according to the proposed motor vehicle lock arrangement, Fig. 4 an embodiment of a proposed motor vehicle lock with a proposed locking element or of a first motor vehicle lock according to a proposed motor vehicle lock arrangement, Fig. 5 an embodiment of a proposed motor vehicle lock with a proposed locking element in a rear view of Fig. 4 or a first motor vehicle lock according to a proposed motor vehicle lock arrangement and Fig. 6 an embodiment of the second motor vehicle lock of a proposed motor vehicle lock arrangement.

[0039] The figures show various preferred embodiments. Fig. 1a ) shows a motor vehicle 1 with several proposed motor vehicle locks 2.

[0040] It should be noted in advance that the drawing only shows those components of the proposed motor vehicle lock 2 that are necessary for explaining the teaching. For example, any locking mechanism that may be provided to realize functional states such as "locked", "unlocked", "theft-proof" or the like is not shown.

[0041] The illustrated motor vehicle lock 2 can be applied to virtually all locking elements 3 of a motor vehicle 1. Reference may be made to the introductory part of the description in this respect. In the embodiment of the exemplary embodiment, the motor vehicle lock 2 is particularly advantageous for use on tailgates or trunk lids.

[0042] The proposed motor vehicle lock 2 has a locking mechanism 4 with several locking parts 5. A locking part 5 can, for example, be like the proposed one in the Fig. 1b ) shown section 5 of the barrier.

[0043] The proposed locking element 5 for a locking mechanism 4 of a motor vehicle lock 2 can, in particular, be designed as a lock latch 6, as shown in the exemplary embodiment. The locking element 5 has a first locking contour 7 for locking the motor vehicle lock 2 in a first locked state, in particular a main locked state.

[0044] It is essential that the locking element 5 has a second locking contour 8 for locking the vehicle lock 2 in a further locked state, in particular a pre-locked state, which is deactivated. The deactivation means that the second locking contour 8 is not accessible to another locking element 5 for locking purposes.

[0045] This creates a locking element 5 with a first and second locking contour 8, one of which is inactive. The idea behind this is to develop and physically design the locking element 5 in such a way that both a vehicle lock 2 with a multi-position locking mechanism, in particular a two-latch lock, and a vehicle lock 2 with fewer locking positions, in particular with a single-position locking mechanism or single-latch lock, can be provided in a simple and cost-effective manner. This can be achieved by deactivating one locking contour of a locking element 5. By deactivating one of the locking positions or latches 9 of the locking element 5, a locking mechanism 4 for another vehicle lock 2 can be derived particularly easily from a multi-position locking mechanism.

[0046] This can, for example, save on development and production costs for an additional locking mechanism 4 or vehicle lock 2. In particular, if a multi-position locking mechanism is already designed in such a way that one fewer locking position can be implemented, development costs for the additional locking mechanism 4 or vehicle lock 2 can be reduced, and economies of scale in the production of both vehicle locks 2 can be achieved through the use of identical parts.

[0047] In particular, by simply exchanging a locking part 5, which is installed on the one hand with activated second locking contour 8 and on the other hand with deactivated second locking contour 8, especially in the same motor vehicle lock production line, two different motor vehicle locks 2 for different requirements can be produced in a simple and particularly cost-effective manner.

[0048] In the exemplary embodiment, the locking element 5 is designed to pivot about a pivot axis. It can pivot from an open position to a closed position, in particular the main closed position. Here, it assumes the open position when the vehicle lock 2 is open and the closed position when the vehicle lock 2 is closed.

[0049] The first locking contour 7 and the second, deactivated locking contour 8 are in the Fig. 1a ) shown. The first locking contour 7 and the second locking contour 8 are arranged on the locking element 5 such that, in the activated state, they lock the locking element 5 against movement in the same direction, in particular the same direction of rotation. Here, and preferably, the first locking contour 7 and the second locking contour 8 are arranged on the same plane.

[0050] Furthermore, and preferably, the locking element 5 comprises a metal body 10 and a plastic body 11. The metal body 10 is preferably designed as a stamped part.

[0051] The first locking contour 7 can be provided on the metal body 10. Furthermore, the second locking contour 8 can additionally or alternatively be provided on the metal body 10. To deactivate the second locking contour 8, the plastic body 11 preferably covers the second locking contour 8. This makes it possible to design the vehicle locks 2 and / or the locking mechanisms 4 of the vehicle locks 2 of the proposed vehicle lock arrangement with an identical metal body 10. The variants can be formed, in particular solely, by a modified plastic body 11 or a modified casing 12.

[0052] Particularly preferably, the plastic body 11 is injection-molded over the metal body 10 and / or the plastic body 11 and the metal body 10 are positively and / or force-fittedly connected to each other, in particular by clips. Additionally or alternatively, it can be provided that the plastic body 11 and the metal body 10 are materially bonded to each other.

[0053] In the illustrated and thus preferred embodiment, the plastic body 11 is designed as a casing 12 for the metal body 10, which is preferably produced by injection molding.

[0054] Is the locking part 5 designed as a lock latch 6, as in the Fig. 1 As shown, it has, in particular on its metal body 10, a latch entry jaw 13 for the locking element 14. As shown in the exemplary embodiment, the first locking contour 7 can be arranged in the area of ​​the latch entry jaw, and / or the second locking contour 8 can be arranged in the area of ​​the latch entry jaw 13. This allows for a compact design of the motor vehicle lock 2.

[0055] Furthermore, the pivot bearing 15 of the locking part 5 can be provided at least partially by the metal body 10, and it is also possible in principle that the plastic body 11 provides at least part of the pivot bearing 15.

[0056] Furthermore, it is preferably provided here that the first locking contour 7 is provided on the metal body 10, in particular on the circumference of the metal body 10, and / or that the second locking contour 8 is provided on the metal body 10, in particular on the circumference of the metal body 10, as shown in the Fig. 1b ) is shown.

[0057] Furthermore, it is provided here that the plastic body 11 encloses the first locking contour 7, in particular on all sides. Such a design is particularly easy to implement if the plastic body 11 is designed as a casing 12 of the metal body 10. In this case, the locking contour can be realized, in particular, by a cutout in the plastic body 11.

[0058] Furthermore, in the illustrated and thus preferred embodiment, the second locking contour 8 is offset outwards relative to the first locking contour 7 with respect to a pivot bearing 15 of the locking element 5. This allows for particularly good design and adjustment of the locking contours and the force acting in the closing states associated with the respective locking contours. In particular, this also makes it particularly easy to adjust different engagement depths of a further locking element 5 for the associated closing states.

[0059] Furthermore, it is preferably provided here that the first locking contour 7 is designed as a detent 9, in particular as a main detent 16, of the locking part 5, and / or that the second locking contour 8 is designed as a deactivated detent 9, in particular as a deactivated pre-detent 17, of the locking part 5.

[0060] The pre-latch 17 and / or the main latch 16 are characterized here, and preferably each, by latching recesses 18 on the locking part 5, particularly on its circumference, especially on the metal body 10 of the locking part 5, which engage in the activated state. In the exemplary embodiment, and preferably, the latches 9, in their respective activated states, each have a double reversal of curvature 19 on the circumference of the locking part 5 when viewed from above.

[0061] Furthermore, it is preferably provided here that deactivation is ensured by a covering section 20, in particular of the plastic body 11. This is a particularly simple way to deactivate the second locking contour 8. In the exemplary embodiment of the Fig. 1b ) the cover section 20 extends outwards in the closing direction of rotation of the locking part 5 with respect to the pivot bearing 15 of the locking part 5.

[0062] Additionally or alternatively, a pocket 21 may be provided in the area of ​​the overlap section 20. This allows for additional damping of an impact of another locking part 5 on the proposed locking part 5 in this area, and thus a reduction in the operating noise of the vehicle lock 2.

[0063] Furthermore, it is preferably provided that the locking element 5 has an engagement contour 22 for a closing aid 23. In particular, the engagement contour 22 can be provided on the metal body 10. This allows a closing aid 23 to be implemented in a particularly simple manner at least in one of the vehicle locks 2 of the proposed vehicle lock arrangement.

[0064] The design allows the engagement contour 22 to be activated and / or deactivated for the closing aid 23. The activated engagement contour 22 allows the lock latch 6 to be gripped and pulled into the closed position by actuating the closing aid 23. Deactivation prevents the engagement contour 22 from being accessed by the closing aid 23. Preferably, the engagement contour 22 is deactivated by the plastic body 11 and / or a casing 12 in the area of ​​the engagement contour 22. This allows the engagement contour 22 to be activated and / or deactivated easily, particularly simply by the plastic body 11 or the casing 12. In particular, the metal body 10 can then be designed identically for different motor vehicle locks 2 with and / or without a closing aid 23.

[0065] A motor vehicle lock 2 with a locking mechanism 4 is further proposed, wherein the locking mechanism 4 comprises a latch 6 and a locking pawl system 24. The locking pawl system 24 can be moved into an open position and a closed position. The motor vehicle lock 2 has an open state in which the latch 6 is pivoted into an open position, and it has a closed state, in particular a main closed state, in which the latch 6 is pivoted into a closed position, in particular a main closed position. In the closed position, the latch 6 is locked at its first locking contour 7 by an engagement with the locking pawl system 24 in the closed position, in particular a main closed position.

[0066] Furthermore, it is provided that the lock latch 6 is designed as a locking part 5 according to the described type and / or that the motor vehicle lock 2 does not assume any further closed state when the lock latch 6 is adjusted from the open position to the closed position and that the locking pawl system 24 for the lock latch 6 is designed and arranged in such a way that by providing a second locking contour 8 on the lock latch 6 an additional closing position for a further closing state of the motor vehicle lock 2, in particular pre-locking state 17, is possible.

[0067] The underlying idea is to develop and physically design the motor vehicle lock 2 and / or the locking part 5 in such a way that a simpler locking mechanism 4 for another motor vehicle lock 2 can be derived particularly easily from a motor vehicle lock 2 with a multi-position locking mechanism, in particular a two-latch locking mechanism, by deactivating one of the locking positions or latches 9 or by replacing a locking part 5, in particular the lock latch 6.

[0068] This can, for example, save on development and production costs for an additional locking mechanism 4 or vehicle lock 2.

[0069] In particular, by simply exchanging a locking part 5, which is installed on the one hand with activated second locking contour 8 and on the other hand without second locking contour 8 or with deactivated second locking contour 8, especially in the same motor vehicle lock production line, two different motor vehicle locks 2 for different requirements can be produced in a simple and particularly cost-effective manner.

[0070] Reference may be made to all statements concerning the proposed locking part 5.

[0071] The locking mechanism 4 with the latch 6 and a locking pawl system 24 is in the Figuren 2 and 3 shown. The lock trap 6 is in the Fig. 2b ) disclosure shown and in the Fig. 2a The main locking position shown is pivotable. The latch 6 is spring-loaded here and preferably in the open position. When the vehicle lock 2 is installed, the latch 6, in a locked position, engages with a locking element 14, in particular a locking bolt, or the like. Preferably, the vehicle lock 2 is arranged on the relevant locking element 3, for example, the vehicle door or the like, and the locking element 14 is arranged on the vehicle body. Alternatively, the vehicle lock 2 can be arranged on the vehicle body and the locking element 14 on the relevant locking element 3, for example, the vehicle door or the like.

[0072] Furthermore, and preferably, the locking pawl system 24 has a primary locking pawl 25 that can pivot between an open position and a closed position. The primary locking pawl 25 is spring-loaded in the open position. The proposed motor vehicle lock 2 can, in principle, be designed as a single-latch lock. However, it is preferably designed as a double-latch lock, as is also shown in the exemplary embodiments.

[0073] Therefore, the locking pawl system 24 can also have a secondary locking pawl 26 that pivots between an open and a closed position. The secondary locking pawl 26 is spring-loaded, preferably in the open position. In particular, if a secondary locking pawl 26 is provided, the primary locking pawl 25 can be designed to be self-opening in the main closed state of the vehicle lock 2. This means that the primary locking pawl 25 can be forced out of its closed position by pressure from the lock latch 6.

[0074] In the Fig. 2a The locking mechanism 4 is shown in the main locked state of the vehicle lock 2. The latch 6 is in its locked position, here the main locked position. The locking pawl system 24 is also in its locked position. The primary locking pawl 25 is engaged with the first locking contour 7 in the locked position and prevents the latch 6 from opening. For this purpose, the primary locking pawl 25 preferably has a first engagement section 27, against which the latch 6, with its first locking contour 7, rests in the main locked state. The secondary locking pawl 26 is engaged with the primary locking pawl 25 in its locked position and prevents the primary locking pawl 25 from opening. The secondary locking pawl 26 locks the vehicle lock 2.

[0075] In the closed state, in particular the main closed state, the lock latch 6 is pivoted into a closed position, in particular the main closed position, and is locked at its first locking contour 7 by an engagement with the primary locking pawl 25 in the closed position and by an engagement of the primary locking pawl 25 with the secondary locking pawl 26 in its closed position.

[0076] Such a design makes it possible to achieve particularly low opening forces for the vehicle lock 2.

[0077] Furthermore, it is preferably provided here that when the second locking contour 8 is activated and made accessible, or when the second locking contour 8 is provided, the locking latch system 24 is configured to lock the motor vehicle lock 2 in the further locked state, in particular the pre-locking state. This is described in the Fig. 3 This is illustrated by comparing illustrations a) and b). In this hypothetical pre-locked state, the primary locking pawl 25 would be engaged with the second locking contour 8 in a pre-locked position, preventing the latch 6 from opening. For this purpose, the primary locking pawl 25 preferably has a second engagement section 28, against which the latch 6, with its second locking contour 8, bears in the optionally hypothetical pre-locked state. This second engagement section 28 is preferably arranged relative to the first engagement section 27 with respect to the primary locking pawl pivot axis 29 in the open position direction of the primary locking pawl 25, and in particular on the circumference of the primary locking pawl 25. Preferably, the contour of the first engagement section 27 is more curved than the contour of the second engagement section 28, particularly with respect to the respective length of the respective engagement section.

[0078] In the Fig. 3a ) is the lock 4 of the Fig. 2 with the depiction of the lock trap from the Fig. 1b ) shown, in which the hidden edges of the metal body 10 are depicted with dashed lines. Here, the second locking contour 8 is deactivated. The locking pawl system 24, in particular the primary locking pawl 25, cannot reach the second locking contour 8. It is covered by the plastic body 11 or the casing 12. When the latch 6 is moved from the open position to the closed position, here the main locking position, the vehicle lock 2 does not assume any further closed state. However, the locking pawl system 24 is designed and configured for the latch 6 such that by providing a second locking contour 8 on the latch 6 – as shown in the Fig. 3b ) shown - an additional locking position for a further locking state of the vehicle lock 2, here the pre-locking state, is possible. This only requires exposing the second locking contour 8 on the lock latch 6, for example analogous to the one shown in the Fig. 3 of the type shown, or, of replacing the lock latch 6 with one with two activated locking contours, as shown in the Fig. 3b ) is shown.

[0079] It should be noted here that the latch 6 of the proposed vehicle lock 2 does not need to have a second locking contour 8, but rather that for the implementation of the proposed vehicle lock 2 it is sufficient that the locking pawl system 24 is configured to interact with such a second locking contour 8 to achieve a further locking state. This configuration of the locking pawl system 24 includes not only the structural design of the locking pawl system 24 but also its positioning relative to the latch 6.

[0080] Such a lock latch 6 can also exhibit all the features described in connection with the proposed locking part 5, either individually or in combination.

[0081] In a further preferred embodiment, it can be provided that, upon activation and accessibility of the second locking contour 8, or upon provision of the second locking contour 8, the locking pawl system 24 is designed and configured for the lock latch 6 such that the primary locking pawl 25, in the further closing state, particularly the pre-closing state, locks the lock latch 6 and the primary locking pawl 25 is released by the secondary locking pawl 26. Preferably, different engagement depths are then realized or can be realized for the primary locking pawl 25 for the pre-latch 17 and the main latch 16.

[0082] The primary locking pawl 25 and / or the secondary locking pawl 26 can and preferably can be designed as push-type locking pawls. These generally allow for a more compact design of the vehicle lock 2. Alternatively, the primary locking pawl 25 and / or the secondary locking pawl 26 can also be designed as pull-type locking pawls.

[0083] Furthermore, it is preferably provided here that a release lever 30 is provided for opening the vehicle lock 2, in particular by motor. This release lever 30 is located in the Fig. 4 As shown, it can be actuated here by an electric motor 31, preferably via a cable 32 or the like, located in the vehicle lock 2. The release lever 30 is located here, and preferably in a different plane than the locking mechanism 4. In the exemplary embodiment, the release lever 30 is located in a plane parallel to and above the plane of the locking mechanism 4.

[0084] Here, and preferably, the release lever 30 is configured to act first on the secondary locking pawl 26 and then on the primary locking pawl 25 to open the vehicle lock 2. Preferably, the release lever 30 acts directly on the secondary locking pawl 26 to open the vehicle lock 2.
