Abstract

The invention relates to a locking element for a locking mechanism (4) of a motor vehicle lock (2), in particular a latch (6), with a first locking contour (7) for locking the motor vehicle lock (2) in a first locked state, in particular the main locked state. It is proposed that the locking element (5) has a second locking contour (8) for locking the motor vehicle lock (2) in a further locked state, in particular a pre-locking state, which is deactivated, such that the deactivation prevents the second locking contour (8) from being accessible for locking by another locking element (5).

Description

[0001] The present invention relates to a locking part for a locking mechanism of a motor vehicle lock according to the preamble of claim 1 and a motor vehicle lock according to the preamble of claim 9 and a kit for a motor vehicle lock according to claim 17 and a motor vehicle lock arrangement according to claim 18 and a method for producing 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 used for all types of locking elements of a motor vehicle. The locking element can generally be mounted on the motor vehicle in a pivotable and / or longitudinally displaceable manner. Furthermore, it can, in particular, be pivotable substantially about a horizontal or substantially about a vertical pivot axis.

[0003] Such closure elements include, for example, side doors, in particular sliding doors, tailgates, trunk lids, engine hoods, loading compartment floors or the like of a motor vehicle.

[0004] EP 3 688 257 A1, for example, describes a motor vehicle lock comprising a lock latch and a pawl system with a primary pawl and a secondary pawl as locking components. The lock latch can be moved into a main locking position and, if necessary, a pre-locking position. A pre-locking position and a main locking position are provided on the lock latch of the motor vehicle lock, corresponding to these two locking positions.

[0005] Although the teaching of EP 3 688 257 A1 implies that the pre-locking position may also not be realized, whether and how the locking parts, lock latch, primary pawl and secondary pawl, should then be physically designed and arranged in relation to one another is not described in EP 3 688 257 A1.

[0006] Starting with 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 part by the features of the characterizing part of claim 1.

[0009] The fundamental idea is to use a locking part for a motor vehicle lock, in particular a previously 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 in which one locking position, or one less, is sufficient. The fundamental idea here is to simply deactivate the second locking contour of the locking part. This can be achieved by designing the second locking contour inaccessible to another locking part.

[0010] The idea is to further develop the motor vehicle lock and the locking part and to design them physically in such a way that a simpler locking mechanism for another motor vehicle lock can be easily derived from a motor vehicle lock with a multi-locking position locking mechanism, in particular a two-notch locking mechanism, by deactivating one of the locking positions or notches.

[0011] This can, for example, save development and production costs for an additional locking mechanism or vehicle lock. Particularly in the case where a multi-locking position locking mechanism is already designed to accommodate one less locking position, development costs for the additional locking mechanism 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 part, which is installed on the one hand with the second locking contour activated and on the other hand with the second locking contour deactivated, in particular in the same motor vehicle lock production line, two different motor vehicle locks for different requirements can be produced in a simple manner and particularly cost-effectively.

[0013] In detail, for a locking part for the locking mechanism of 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 further 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 has the effect that the second locking contour is not accessible for another locking part for locking the motor vehicle lock.

[0014] A preferred development of the locking part is described in claim 2, which describes a particularly preferred design of the locking part. A particularly simple and cost-effective method of adapting the locking part 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, particularly in the event of a crash.

[0016] Claims 4 to 7 describe particularly preferred embodiments of the locking part, which allow a particularly simple and advantageous construction of the pawl system for a locking mechanism with such a locking part.

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

[0018] According to a further teaching according to 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 part according to the type described and / or that the motor vehicle lock does not assume any further closed state when the lock latch is adjusted from the open position to the closed position and that the pawl system is designed to realize an additional closed position for a further closed state of the motor vehicle lock, in particular a pre-locking state, by providing a second locking contour on the lock latch.

[0020] The idea behind this is to develop and physically design the motor vehicle lock and / or the locking part in such a way that a simpler locking mechanism for another motor vehicle lock can be easily derived from a motor vehicle lock with a multi-locking position locking mechanism, in particular a two-notch locking mechanism, by deactivating one of the locking positions or notches and / or by replacing a locking part.

[0021] This can, for example, save development and production costs for an additional locking mechanism or vehicle lock. Particularly in the case where a multi-locking position locking mechanism is already designed to accommodate one less locking position, it is possible to reduce development costs for the additional locking mechanism or vehicle lock and leverage economies of scale in the production of both vehicle locks by using identical parts.

[0022] In particular, by simply exchanging a locking part, 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, in particular in the same motor vehicle lock production line, two different motor vehicle locks for different requirements can be produced in a simple manner and particularly cost-effectively.

[0023] Reference may be made to all statements relating to the proposed locking part.

[0024] According to the preferred embodiment according to claim 10, the pawl system can be designed as a single-pawl system or as a two-pawl system, whereby the latter can reduce the forces required for opening the motor vehicle lock.

[0025] According to the preferred embodiment according to claim 11, the lock latch and the locking pawl system are arranged and designed in such a way that when the second locking contour is activated and made accessible, 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 the closing of the motor vehicle lock and an interruption of the closing process by means of a closing aid.

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

[0030] According to a further teaching according to claim 17, which also has 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 instead 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 instead of the lock latch, the first locking contour of the further lock latch is accessible to the pawl system for generating the main locking state, and the second locking contour of the further lock latch is accessible to the pawl system for generating the further locking state as a pre-locking state.

[0031] Reference is made to all statements regarding the proposed locking mechanism and the proposed motor 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 type described 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 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 pawl system in a further locking state, in particular pre-locking state, which is activated and accessible.

[0033] Reference is made to all statements regarding the proposed locking mechanism and motor vehicle lock, as well as to the proposed modular system and the advantages described therein. These statements also apply analogously to the motor vehicle lock arrangement.

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

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

[0036] It is essential that the first motor vehicle lock is assembled in a production line for producing motor vehicle locks and the second motor vehicle lock is assembled in the same production line, preferably that either the lock latch of the first motor vehicle lock or the lock latch of the second motor vehicle lock is installed at the same station of the production line for producing the first motor vehicle lock or the second motor vehicle lock, 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 relating to the proposed locking part, motor vehicle lock, modular system and the proposed motor vehicle lock arrangement.

[0038] In the following, the invention is explained in more detail with reference to a drawing which merely represents exemplary embodiments. In the drawing, Fig. 1 in a) a motor vehicle with proposed motor vehicle locks and b) a proposed locking part in the form of a lock latch, Fig. 2 the locking mechanism of a proposed motor vehicle lock in a) in a closed state and in b) in an open state, Fig. 3 the locking mechanism of the motor vehicle locks of a proposed motor vehicle lock arrangement, wherein a) shows the locking mechanism of a proposed motor vehicle lock with a proposed locking part and b) shows the locking mechanism 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 part 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 part 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 for implementing 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. In this regard, reference is made to the introductory part of the description. 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 one proposed in the Fig. 1b ) shown locking part 5.

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

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

[0045] This creates a locking part 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 part 5 in such a way that both a motor vehicle lock 2 with a multi-locking position locking mechanism, in particular a two-notch locking mechanism, and a motor vehicle lock 2 with fewer locking positions, in particular with a single-locking position locking mechanism or single-notch locking mechanism, can be provided in a simple and cost-effective manner. This can be achieved by deactivating a locking contour of a locking part 5. By deactivating one of the locking positions or notches 9 of the locking part 5, a locking mechanism 4 for another motor vehicle lock 2 can be derived particularly easily from a multi-locking position locking mechanism.

[0046] This can, for example, save development and production costs for an additional locking mechanism 4 or motor vehicle lock 2. Particularly in the case where a multi-locking position locking mechanism is already designed in such a way that one less locking position can be realized, development costs for the additional locking mechanism 4 or motor vehicle lock 2 can be reduced and economies of scale in the production of the two motor 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 the second locking contour 8 activated and on the other hand with the second locking contour 8 deactivated, in particular in the same motor vehicle lock production line, two different motor vehicle locks 2 for different requirements can be produced in a simple manner and particularly cost-effectively.

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

[0049] The first locking contour 7 and the second, deactivated locking contour 8 are in the Fig. 1a ). The first locking contour 7 and the second locking contour 8 are arranged relative to one another on the locking part 5 such that, in the activated state, they lock the locking part 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, it is preferably provided here that the locking part 5 has a metal body 10 and a plastic body 11. The metal body 10 is preferably formed 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 motor vehicle locks 2 and / or the locking mechanism 4 of the motor vehicle locks 2 of the proposed motor 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 connected to one another in a form-fitting and / or force-fitting manner, in particular by clipping. Additionally or alternatively, it can be provided that the plastic body 11 and the metal body 10 are connected to one another in a material-fitting manner.

[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] If the locking part 5 is designed as a lock latch 6, as in the Fig. 1 As shown, it has, particularly on its metal body 10, a lock latch inlet opening 13 for the locking part 14. As shown particularly in the exemplary embodiment, the first locking contour 7 can be arranged in the region of the lock latch inlet opening, and / or the second locking contour 8 can be arranged in the region of the lock latch inlet opening 13. This allows a compact design of the motor vehicle lock 2 to be realized.

[0055] In addition, the pivot bearing 15 of the locking part 5 can be provided at least partially by the metal body 10, whereby it is also possible in principle for the plastic body 11 to provide 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 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 configuration 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, in this respect, preferred embodiment, the second locking contour 8 is offset outward relative to the first locking contour 7 with respect to a pivot bearing 15 of the locking part 5. This allows for particularly good design and adjustment of the locking contours and the force effects in the locking states associated with the respective locking contours. In particular, this also allows for a different insertion depth of a further locking part 5 to be adjusted particularly easily for the associated locking states.

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

[0060] The preliminary detent 17 and / or the main detent 16 are each characterized here and preferably by detent recesses 18 on the locking part 5, in particular on its circumference, in particular on the metal body 10 of the locking part 5, which engage in the activated state. In the exemplary embodiment and preferably, the detents 9 each have a double curvature reversal 19 on the circumference of the locking part 5 in a top view of the locking part 5 in their activated state.

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

[0062] Additionally or alternatively, a pocket 21 may be formed in the area of ​​the overlapping 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 motor vehicle lock 2.

[0063] Furthermore, it is preferably provided here that the locking part 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 in at least one of the motor vehicle locks 2 of the proposed motor vehicle lock arrangement.

[0064] It can be provided that the engagement contour 22 is activated and / or deactivated for the closing aid 23. The activated engagement contour 22 allows the lock latch 6 to be engaged and pulled into the closed position by actuating the closing aid 23. Deactivation means that the engagement contour 22 is not accessible for a closing aid 23 for closing. Preferably, the engagement contour 22 is deactivated by the plastic body 11 and / or a casing 12 in the region of the engagement contour 22. As a result, the engagement contour 22 can be activated and / or deactivated in a simple manner, in particular 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 the closing aid 23.

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

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

[0067] The idea behind this 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-locking position locking mechanism, in particular a two-notch locking mechanism, by deactivating one of the locking positions or notches 9 or replacing a locking part 5, here in particular the lock latch 6.

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

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

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

[0071] The locking mechanism 4 with the lock latch 6 and a pawl system 24 is in the Figuren 2 and 3 The lock latch 6 is in the Fig. 2b ) shown open position and in the Fig. 2a ) shown main closed position. The lock latch 6 is spring-loaded here and preferably in the open position. The lock latch 6, located in a closed position, is in holding engagement with a locking part 14, in particular a striker, or the like, when the motor vehicle lock 2 is mounted. Preferably, the motor vehicle lock 2 is arranged on the relevant locking element 3, for example the motor vehicle door or the like, and the locking part 14 on the motor vehicle body. Alternatively, the motor vehicle lock 2 can be arranged on the motor vehicle body and the locking part 14 on the relevant locking element 3, for example the motor vehicle door or the like.

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

[0073] In this respect, the pawl system 24 can also have a secondary pawl 26 that can be pivoted between an open position and a closed position. The secondary pawl 26 is spring-loaded here, and preferably in the open position. In particular, if a secondary pawl 26 is provided, the primary pawl 25 can be designed to be self-opening in the main closed state of the motor vehicle lock 2. This means that the primary pawl 25 can be pushed 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 locking state of the motor vehicle lock 2. The lock latch 6 is in its closed position, here the main locking position. The pawl system 24 is also in its closed position. The primary pawl 25 is in the closed position engaged with the first locking contour 7 and prevents the lock latch 6 from opening. For this purpose, the primary pawl 25 here and preferably has a first engagement section 27, against which the lock latch 6 rests with its first locking contour 7 on the primary pawl 25 in the main locking state. The secondary pawl 26 is in its closed position engaged with the primary pawl 25 and prevents the primary pawl 25 from opening. The secondary pawl 26 locks the motor 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 engagement with the primary pawl 25 in the closed position and by engagement of the primary pawl 25 with the secondary pawl 26 in its closed position.

[0076] Such a construction allows particularly low opening forces for the motor vehicle lock 2 to be achieved.

[0077] Furthermore, it is preferably 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 configured to lock the motor vehicle lock 2 in the further locking state, in particular the pre-locking state. This is shown in the Fig. 3 clarified by comparing illustrations a) and b). In this hypothetical pre-closing state, the primary pawl 25 would be in a pre-closing position in engagement with the second locking contour 8 and prevent the lock latch 6 from opening. For this purpose, the primary pawl 25 here and preferably has a second engagement portion 28, against which the lock latch 6 rests with its second locking contour 8 in the possibly hypothetical pre-closing state on the primary pawl 25. This second engagement portion 28 is here and preferably arranged relative to the first engagement portion 27 with respect to the primary pawl pivot axis 29 in the open position direction of the primary pawl 25, in particular arranged on the circumference of the primary pawl 25. The contour of the first engagement portion 27 is preferably more curved than the contour of the second engagement portion 28, in particular with respect to the respective length of the respective engagement portion.

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

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

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

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

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

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

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

[0085] In the example, as in the Fig. 5 As shown, the release lever pivot axis 33 is arranged coaxially with the secondary pawl pivot axis 34. Alternatively, the release lever pivot axis 33 can be arranged coaxially with the primary pawl pivot axis 29. These arrangements allow a compact construction of the motor vehicle lock 2 and, in particular, make it possible to arrange the release lever 30 on the same bearing dome as one of the pawls.

[0086] Furthermore, it is preferably provided that the motor vehicle lock 2 has an actuating lever 35 that can be manually operated from the outside of the lock for opening the motor vehicle lock 2. As in the Fig. 4 As shown, the operating lever 35 for opening the motor vehicle lock 2 preferably acts on the release lever 30.
