[0003] Description

[0004] LOCK, IN PARTICULAR TAILGATE LOCK, FOR A MOTOR VEHICLE

[0005] The invention relates to a lock, in particular a tailgate lock, for a motor vehicle comprising a locking mechanism with a rotary latch and at least one pawl, wherein the rotary latch can be locked in a pre-latching position and a main latching position, a closing and opening drive, wherein the locking mechanism can be moved from a pre-latching position to a main latching position by means of the closing drive, and a closing pawl, wherein the closing pawl enters a holding position after reaching the main latching position of the rotary latch.

[0006] Modern motor vehicles increasingly incorporate electrically assisted operating and functional elements. These electrically assisted systems make it easier for the user to operate the vehicle or, for example, to get in and out. The invention relates to motor vehicle locks, such as those used in doors, sliding doors, or tailgates. It is already common practice for these locks to be equipped with electric drives that enable the lock to be opened electrically and / or the door or tailgate to be closed electrically.

[0007] From DE 10 2009 020 488 A1, a motor vehicle lock with an electric drive is known. Such a motor vehicle lock typically has a rotary latch that includes at least one main detent. In the closed position, the rotary latch engages a locking bolt or a lock holder, which may, for example, be attached to a vehicle body. The rotary latch engages with a pawl, which secures the rotary latch against rotation in the main detent by means of a positive locking mechanism. Furthermore, the motor vehicle lock includes an electromechanical drive unit. Functional elements of the drive unit act on the locking bolt via a pawl mechanism.

[0008] P24156WO 2 17 March 2026 Kiekert Aktiengesellschaft

[0009] The locking pawl of the vehicle lock. This allows the locking pawl to be moved around a pivot axis of the locking pawl together with the drive element, thereby unlocking, for example, the rotary latch. To secure the position of the functional elements, the publication discloses friction contacts that maintain the holding position of the functional elements when the drive element is deactivated.

[0010] On the one hand, the end positions can be reliably maintained using, for example, friction devices; on the other hand, end stops are also used to decelerate the functional elements or to reach a defined holding position. For example, it is known from DE 10 2013006521 A1 to use an electric drive to unlock a lock, wherein the electric drive interacts with a locking lever, the locking lever representing a fixed stop for the drive. Depending on the direction of rotation of the drive, an end position, i.e., a stop position, can be assumed.

[0011] A closing and opening device for a motor vehicle door lock is disclosed in DE 102013 106672 A1. The closing and opening device is equipped with a drive and a transmission element. A locking mechanism is also incorporated. The drive operates via the transmission element on the locking mechanism to open or close it. The closing drive can move the locking mechanism from a pre-lock position to a main lock position, with this movement being effected by means of a variable torque.

[0012] The generic prior art is defined by DE 102023 101 262 A1. This document discloses a lock, in particular a tailgate lock for a motor vehicle, comprising a locking mechanism with a rotary latch and at least one pawl, wherein the rotary latch can be engaged in a pre-engagement position and a main engagement position, and a closing drive, wherein the locking mechanism is moved from a pre-engagement position to a main engagement position by means of the closing drive.

[0013] P24156WO 3 17 March 2026 Kiekert Aktiengesellschaft

[0014] The closing mechanism is transferable, and the closing drive, after reaching the main detent position, can be moved to a holding position located before the main detent position. The holding position is characterized by a closing pawl being moved into a position where it is able to immediately re-engage with the rotary latch. To open the lock, the locking mechanism is guided by the closing pawl. The closing pawl itself is moved out of engagement with the rotary latch by means of an extension on the locking pawl.

[0015] The locking systems and automotive locks according to the invention utilize locking mechanisms that have a pre-latch position and a main latch position. In other words, the lock or locking system inherently incorporates a locking mechanism consisting of a rotary latch and at least one pawl. When closing, for example, a tailgate, and particularly when closing an electric tailgate, the tailgate moves into the area of ​​a lock holder, or vice versa, with the locking system and the lock holder interacting. Typically, when the tailgate is closed, the locking system first moves into the pre-latch position, in which the rotary latch is held by the pawl. The locking mechanism can then be moved into the main latch position by means of the closing drive.

[0016] When the lock is opened, the electric drive also releases the locking pawl from the rotary latch, thus freeing the rotary latch and allowing the tailgate to be opened, either manually or electrically. Depending on the load acting on the lock, the release of the locking pawl from the rotary latch can produce a more or less loud opening noise, sometimes referred to as a "pop." A constant goal for both car manufacturers and the developers of locking systems is to make the opening noise as quiet as possible, thereby creating a perceived quality feature for the user. However, quiet opening is not the only desired factor; the available space and the number of components used must also be considered. The aim is to achieve this with the fewest possible components.

[0017] P24156WO 4 17 March 2026 Kiekert Aktiengesellschaft

[0018] High functionality can be achieved in a small installation space. This is where the invention comes in.

[0019] The object of the invention is to provide an improved vehicle lock. Furthermore, it is an object of the invention to provide a vehicle lock in which high functionality can be achieved with the fewest possible components in a small installation space. Finally, it is an object of the invention to provide a structurally simple and cost-effective solution for quiet opening of a vehicle lock.

[0020] The problem is solved by the features of independent claim 1. Advantageous embodiments are specified in the dependent claims. It should be noted that the exemplary embodiments described below are not limiting; rather, any number of variations of the features described in the description and the dependent claims are possible.

[0021] According to claim 1, the object of the invention is achieved by providing a lock, in particular a tailgate lock for a motor vehicle, comprising a locking mechanism with a rotary latch and at least one pawl, wherein the rotary latch can be locked in a pre-latching position and a main latching position, a closing and opening drive, wherein the locking mechanism can be moved from a pre-latching position to a main latching position by means of a closing pawl of the closing drive, and wherein the closing pawl, after reaching the main latching position of the rotary latch, enters a holding position and the closing pawl can be lifted by means of a release lever.

[0022] The inventive design of the motor vehicle lock now makes it possible to move the locking pawl out of engagement with the rotary latch. This is particularly advantageous because the release lever simultaneously moves the locking pawl, so that the lock can be unlocked at any time.

[0023] P24156WO 5 17 March 2026 Kiekert Aktiengesellschaft

[0024] and, in parallel, the closing mechanism can be released from engagement with the rotary latch. A release lever is typically used to move the pawl. When the lock is in a pre-latch or main latch position, the release lever is moved, which then disengages the pawl from engagement with the rotary latch. The pawl can be designed as a separate component or integrally connected to the release lever. According to the invention, the release lever has a dual function. As described above, the release lever primarily serves to deflect the pawl. However, according to the invention, the closing pawl can also be disengaged from engagement with the rotary latch by means of the release lever. The integration of these additional functions into the vehicle lock reduces the number of necessary components while ensuring a high level of functionality.

[0025] A further advantage resulting from the release lever lifting the locking pawl is that the vehicle lock according to the invention is capable of quiet opening. This is achieved by the locking pawl, which, on the one hand, moves the locking mechanism into an overtravel position for closing and, on the other hand, moves the locking mechanism from a main detent position to an overtravel position when opening. Subsequently, the locking pawl is moved out of the engagement area of ​​the rotary latch, and finally, the rotary latch is guided into an open position or a release position by means of the locking pawl. The locking pawl thus serves both to close the locking mechanism and is also used during the opening process.Because the release lever interacts directly with the closing latch, the closing latch can be disengaged from the rotary catch at any time, regardless of the silent opening mechanism. Interrupting the closing process, as well as interrupting the silent opening, can therefore be achieved through the interaction of the release lever and the closing latch.

[0026] P24156WO 6 17 March 2026 Kiekert Aktiengesellschaft

[0027] When the invention refers to a lock for a motor vehicle, this means locks or motor vehicle locking systems used in motor vehicles. These can be locking systems for hoods, side doors, sliding doors, tailgates, covers, or other locking systems in motor vehicles, which are used wherever pivotally or slidably arranged components must be securely positioned and held during the operation of the motor vehicle. The terms "lock," "locking system," and "motor vehicle lock" are used synonymously.

[0028] The lock features a locking mechanism with a rotary latch and at least one pawl. Different pawls can be used, interacting with the rotary latch in various ways. For example, in a main locking position, a closing or opening torque might be present, so that in the case of an opening torque, the pawl could be additionally secured in the main locking position by an auxiliary pawl or a blocking lever.

[0029] The locking mechanism according to the invention has a pre-locking position and a main locking position. When, for example, a side door is closed for the first time, the locking mechanism, in conjunction with a lock holder, moves into a pre-locking position. From this pre-locking position, the locking mechanism or the rotary latch can be moved into the main locking position by means of the closing drive. The closing drive acts directly on the rotary latch and moves it from the pre-locking position to the main locking position. In the main locking position, the locking pawl rests against a main detent of the rotary latch.

[0030] Using the opening drive, the rotary latch can be moved from the main detent position into an overstroke position, thus releasing the rotary latch from the pawl. In the overstroke position, the pawl is moved out of the engagement area with the rotary latch, and then the rotary latch is opened by means of the

[0031] P24156WO 7 17 March 2026 Kiekert Aktiengesellschaft

[0032] The latching mechanism is moved beyond its main detent position into an open position. In other words, the rotary latch is opened in a guided manner, so that the lock holder is moved from the overtravel position of the rotary latches into its release position.

[0033] In the main detent position and especially in the overtravel position, high door seal pressures act on the locking mechanism, which can cause noise when the locking pawl is moved out of engagement by the rotary latch. According to the invention, if the rotary latch is first moved into an overtravel position, so that the door element is pressed further towards the door seal and the locking pawl is released from the rotary latch, the locking pawl can be moved out of engagement with the rotary latch without load. An opening noise or bang can be avoided or prevented by moving the rotary latch into the overtravel position to open the locking mechanism.

[0034] In a further embodiment of the invention, the release lever can be actuated by means of the closing and opening drive. The release lever extends from a pivot axis of the pawl, across the pawl, to the closing and opening drive. The closing and opening drive is powered by an electric motor and a downstream one-, two-, or more-part gearbox. When the operator sends an opening signal to the vehicle lock, the release lever is actuated by the closing and opening drive. The release lever then interacts with the closing pawl, so that after the locking pawl is released by the release lever and the rotary latch is moved into a release position, the closing pawl is lifted from the rotary latch by the release lever.By activating the locking pawl and the pull-out pawl at different times, it is possible to unlock the lock on the one hand and to move the locking pawl into the release position on the other.

[0035] P24156WO 8 17 March 2026 Kiekert Aktiengesellschaft

[0036] In an advantageous embodiment of the invention, the closing and opening drive comprises a cam disk. The closing and opening drive is actuated by means of an electric motor and a gearbox connected downstream of the electric motor. According to the invention, the electric drive acts on a cam disk, that is, a cam disk driven directly or indirectly by the electric drive, which includes a control cam. The control cam engages with a drive lever, and the drive lever engages with the closing pawl. The electric drive thus transmits the drive force to the closing pawl, with the drive lever being actuated via the control cam in the cam disk. The cam disk, and thus the closing pawl, moves the rotary latch into the main detent or overtravel position and is able, via the closing and opening drive, to move or guide the rotary latch from the overtravel position into a release position for the closing pawl.

[0037] If the cam disc has an opening cam, and the release lever can be actuated by means of this opening cam, a further embodiment of the invention results. The cam disc then takes over the function of pivoting the release lever. As already explained above, the locking pawl and release lever are pivotably mounted in the metal lock case of the vehicle lock via a common pivot point. The cam disc is preferably also rotatably mounted in the lock case and is capable of moving the vehicle lock into the main latch position and releasing the rotary latch during the opening process via a continuous, i.e., unidirectional, rotational movement.The cam disc also features an opening cam that can be engaged with the release lever in such a way that, at the moment the closing pawl has moved the rotary latch from the main detent position to the overtravel position, the release lever is actuated, thus moving the locking pawl out of the engagement area with the rotary latch. Consequently, there is an interaction of the components within the vehicle lock. Starting from the closed position of a tailgate, into which the vehicle lock is integrated, the L...

[0038] P24156WO 9 17 March 2026 Kiekert Aktiengesellschaft

[0039] An electrical signal from the operator activates the electric drive to unlock the locking mechanism. The cam disc moves, transferring the rotary latch from the main detent position to an overtravel position. When the rotary latch is in the overtravel position, the opening cam engages with the release lever, moving the release lever and thus the pawl out of the engagement range, i.e., the pivoting range of the rotary latch. From the now unlocked rotary latch and its position in the overtravel position, a further movement of the cam disc in the same direction moves the rotary latch from the overtravel position, past the main detent position and the pre-detent position, into a release position. The cam disc therefore also serves to unlock the locking mechanism.

[0040] If the release lever is integrally connected to the pawl, a further embodiment of the invention results. The release lever and the pawl can be permanently connected. The pawl is received in the metal lock case by means of the metallic pivot axis. The pawl itself also consists of a metallic core and can have at least a portion of a plastic coating. This plastic coating can extend and be integrally formed with the release lever. The release lever extends sufficiently to engage with the cam and, in particular, the switching cam. The release lever is preferably designed as an injection-molded plastic component.

[0041] It has proven particularly advantageous if the release lever has an ejector arm, whereby the ejector arm can be engaged with the latching pawl. A separate ejector arm on the release lever allows the latching pawl to be guided precisely and as intended, and to be separated from the rotary latch. The release lever thus has a first arm that can be engaged with the cam and by means of which the release lever can be moved. A second arm on the release lever forms L

[0042] P24156WO 10 17 March 2026 Kiekert Aktiengesellschaft

[0043] The ejector arm for the locking pawl can extend along the contour of the rotary latch. In particular, extending it along the rotary latch allows the locking pawl to be ejected precisely at the point where it needs to be released from engagement with the rotary latch. A further advantage is that the extension of the release arm towards the cam disc can be used for manually unlocking the locking mechanism. Specifically, an elongated extension away from the locking pawl and the release lever's axis of rotation offers the advantage of generating large moments at the end of the release lever, thus enabling easy manual unlocking.

[0044] If the ejector arm has a control contour, wherein the control contour can be engaged with a chamfer on the locking pawl, a further embodiment of the invention results. The locking pawl can be guided precisely by means of the control contour on the ejector arm. In particular, in conjunction with the cam disc and thus a movement of the release lever, precise guidance of the locking pawl with respect to the movement sequence of releasing the rotary latch after unlocking the locking mechanism is possible. A structurally simple guide for the locking pawl can be achieved by means of a chamfer on the locking pawl, wherein the chamfer engages with the control contour of the ejector arm. Advantageously, the locking pawl can be held in engagement with the rotary latch in a controlled manner until the rotary latch has reached a release position, and only a small opening force acts on the rotary latch itself.Thus, the latching pawl can be easily ejected from its engagement with the engagement element on the rotary latch, requiring relatively little force. The control contour extends essentially along the ejector arm and therefore in a directed guide along the rotary latch contour, ensuring that the latching pawl remains securely engaged with the rotary latch during its operation.

[0045] P24156WO 11 17 March 2026 Kiekert Aktiengesellschaft

[0046] In a further embodiment of the invention, the release lever is held in a release position by means of the opening cam. In this embodiment, the release lever serves as a multi-function lever in the vehicle lock. The release lever then includes the functions of unlocking, guiding and ejecting the latch, manual groove opening, and a storage lever function. A storage lever function is present when, during the opening movement of the rotary latch, the locking pawl is held out of the engagement area with the rotary latch until the pre-latch and main latch of the rotary latch have passed the detent contour of the locking pawl. In other words, the opening cam on the cam disk, in conjunction with the release lever, prevents the locking pawl from unintentionally engaging in a rotary latch detent position.

[0047] In another embodiment, the release lever has an extension that allows for manual unlocking of the lock. Extending from the pivot axis of the release lever, it reaches far enough to engage the cam disc. If a further extension is formed at a radial end of the release lever, this extension can, for example, be angled relative to the release lever. A chamfer or an angled extension extending from the longitudinal length of the release lever offers the advantage that the extension can protrude from a housing and / or the lock case of the vehicle lock. Thus, the extension, and therefore the release lever, can be designed to be manually accessible, eliminating the need for additional means, such as a pull cord or Bowden cable, to actuate the release lever in the event of, for example, a power failure.It is also conceivable that another means, such as a strap, a Bowden cable, or an engagement eyelet, is attached to the extension to manually actuate the release lever. If the release lever is actuated manually, the locking pawl can be immediately moved out of the engagement area with the rotary latch, and additionally, the control contour on the ejector arm can be used to release the lever.

[0048] P24156WO 12 17 March 2026 Kiekert Aktiengesellschaft

[0049] The pull-tab is moved out of engagement with the pre-locking or engagement mechanism. The release lever, ejector arm, and extension are preferably molded as a single piece.

[0050] Advantageously, at least one microswitch can be arranged in the vehicle lock, wherein the microswitch can be engaged with the release lever, the ejector arm, and / or the locking pawl. The position of the release lever, the ejector arm, the extension, and / or the locking pawl can be detected by means of the microswitch. Thus, a highly functional vehicle lock can be realized and controlled with the simplest design and the fewest possible components.

[0051] The invention is explained in more detail below with reference to the accompanying drawings and a preferred embodiment. However, it is important to note that this embodiment does not limit the invention but merely represents an advantageous configuration. The features shown can be implemented individually or in combination with other features described in the description and claims.

[0057] Fig. 4 shows a detailed view of the control contour of the ejector arm on the trigger lever, showing the release of the pull-lock.

[0058] Figure 1 shows a top view of an open vehicle lock 1. Only those components of the vehicle lock 1 necessary to explain the invention are shown. The vehicle lock 1 comprises a locking mechanism 2, a closing and opening drive 3, and an electric drive (not shown) for the closing and opening drive 3. The vehicle lock 1 is shown in an overtravel position of the locking mechanism 2. A rotary latch 4 is in an overtravel position, with a pawl 5 shown disengaged from the main detent 6 on the rotary latch 4.

[0059] The closing and opening drive 3 comprises a drive lever 7, a cam disk 8 (shown in Fig. 4), a control contour 9, and a closing pawl 10. In this embodiment, a release lever 11 is rotationally fixed to the locking pawl 5. The drive lever 7 is pivotably mounted in a metallic lock case 13 via an axis 12. An engagement sleeve 14 connects the drive lever 7 to the control cam 9, so that a torque generated in the cam disk 8 can be transmitted to the drive lever 7. In other words, the drive lever 7 is moved and controlled via the control cam 9. The control contour 9 is integrally formed with the cam disk 8. The closing pawl 10 is pivotally connected to the drive lever 7.

[0060] As can be clearly seen in Fig. 1, a lock holder 15 is brought into an overstroke position by means of the closing and opening drive 3 via the rotary latch 4. In the overstroke position, the rotary latch is moved further in the closing direction L.

[0061] P24156WO 14 17 March 2026 Kiekert Aktiengesellschaft

[0062] The mechanism moves the lock holder 15 so that, for example, a tailgate held by the vehicle lock 1 is moved further towards the surrounding seal. The force required to hold the lock 1 closed is therefore completely absorbed by the closing and opening drive 3 or the closing latch 10. The lock holder 15 is thus moved further into the vehicle lock 1. An advantage of this is that the locking latch 5 can be moved force-free out of the engagement area and, in this illustrated embodiment, out of the engagement area with the pre-latch 6. The release lever is moved counterclockwise around the axis 17 via an opening cam 16 on the cam disc. By means of a further movement or rotation of the cam disc, the closing latch 10, and thus the rotary latch 4, can then be moved into a release position.

[0063] The guiding of the rotary latch 4 by means of the closing pawl in conjunction with an ejector arm 18 on the release lever 11 is shown in Fig. 2. Fig. 2 depicts the movement of the rotary latch in the opening direction in the direction of arrow P to a release position, in which the closing pawl 10 is released from the rotary latch 4. During the movement to the release position, the closing pawl is held against the pre-latch 20 of the rotary latch 4 by means of a contact surface and preferably by spring tension. The closing pawl 10 engages behind the pre-latch 20 with a hook-shaped end 21, thus enabling the rotary latch to be guided securely in the direction of arrow P to the release position.

[0064] The pull-up pawl 10 also has a chamfer 22 which engages with a control contour 23 on the ejector arm 18. During the movement of the rotary latch or the pull-up pawl 10 in the direction of arrow P, the pull-up pawl 10 is guided over the control contour 23. The control contour 23 extends on the ejector arm 18 essentially along an outer contour of the rotary latch 4, thus ensuring reliable guidance of the pull-up pawl in engagement with the pre-latch 20. The guidance of the pull-up pawl 10 along the control contour 23 is essentially represented by arrow P2.

[0065] P24156WO 15 17 March 2026 Kiekert Aktiengesellschaft

[0066] Fig. 3 shows the vehicle lock 1 in a position where the rotary latch 4 moves into a release position. In this position, the locking pawl 5, and in particular a detent contour 24 on the locking pawl 5, cannot re-engage the main detent 6. The lock holder 15 continues to be guided by the rotary latch or the closing and opening drive.

[0067] In Fig. 4, the rotary latch 4 has reached the release position. The bend 22 engages in an ejector section of the control contour 23 on the ejector arm 18. The control contour 23 is designed such that the locking pawl 10 pivots around the axis 26 on the drive lever 7, and the contact surface 19 and the hook-shaped end 21 are released from the pre-latch 20. In this state of the locking mechanism 2, there is no longer any significant load on the lock holder 15 and thus on the rotary latch 4, so that the locking pawl 10 can be easily and quietly released from engagement with the pre-latch 20. This is clearly evident from the spacing of the mounting surface 19 from the pre-latch 20 and the only slight engagement of the hook-shaped end 21 with the rotary latch 4. The pre-latch 20 is formed by a bend in the metallic part of the rotary latch 4.

[0068] The inventive design of the release lever 11 and its high functionality enable the provision of a compact, highly functional vehicle lock 1 with few components. Furthermore, easy and quiet opening of the vehicle lock 1 is achievable. L P24156WO 16 17 March 2026
