Description

Technical Field

[0001] The present invention relates to a locking device and a vehicle element having a locking device for a movable vehicle element, wherein the locking device is configured as a pull-lock. Background Technology

[0002] EP 2 050 903 B1 discloses a tensioning assist device for tightening a door or flap. The tensioning assist device has a dual function. Its first, general function is to move the pawl from a pre-locked position to a main lock position in the latch during the tightening phase. The second function is to gently move the latch backward in a defined manner in the direction of its open position in the opposite direction to the previous tightening phase. The motor of the tensioning assist device then acts on the tension of the flap or door. The backward movement can be controlled very precisely by sensors and appropriate electronic software, which is both inexpensive and space-saving. Unpleasant opening noise is prevented by electrically resetting the latch through an effective tensioning assist device in the opposite direction. During the reset phase of the tensioning assist device, the force on the seal and spring is released only slowly. The controlled opening movement of the flap or door occurs by rotating the latch and engaging the closing portion therein.

[0003] DE 10 2023 101 262 A1 also discloses a tensioning aid that first places the rotary latch in an overstroke position when the lock is opened. Other tensioning aids are known from DE 10 2007 063 348 A1 and DE 10 2018 113 270 A1. Summary of the Invention

[0004] The object of this invention is to provide a locking device for movable vehicle components (e.g., doors or flaps) that prevents retraction or reset, particularly independent of the position of the unlocking element (flaps or body). Another object of this invention is to provide a vehicle component having such an improved locking device.

[0005] According to the invention, the first objective is achieved by a locking device having the features of claim 1. According to the invention, the second objective is achieved by a vehicle element having the features of claim 16.

[0006] For advantageous improvements, see the dependent claims.

[0007] The locking device according to the invention for movable vehicle components, particularly doors, flaps, engine hoods, etc., is configured as a tension lock and includes at least one locking mechanism having a rotary latch and a locking pawl (locking mechanism), a drive mechanism operably coupled to the locking mechanism for moving it from a closed position to, particularly, an open-open position, or for moving it from an open position to, particularly, a closed-close position, and a tensioning mechanism configured to, by means of the drive mechanism, move the rotary latch in an overstroke closed position and an overstroke open position in the closing and opening directions, respectively.

[0008] The advantages of this invention lie particularly in avoiding the reverse noise known in the prior art. Furthermore, especially in the closing direction after the closing process, the reverse process caused by the reduction in sealing pressure and the resulting noise, particularly opening noise (also known as opening pop or tearing noise), is reduced or even avoided. In the prior art, this opening noise is generated during the reverse of the closing movement, thus partially reopening the rotary latch and closing bracket due to the reduced sealing pressure of the seals acting on the movable vehicle components on the rotary latch. Moreover, fewer position switches, especially microswitches, are required compared to the prior art. In particular, the so-called zero-position switch of the drive mechanism can be omitted. In this way, the locking device configured as a pull-lock has greater compatibility with existing vehicle electrical systems.

[0009] For example, in the opening direction, the locking pawl is placed in the overstroke open position. Furthermore, in the closing direction, the rotary latch is placed in the overstroke closed position and held there, specifically releasably secured.

[0010] In one possible improvement, the tensioning mechanism and the drive mechanism interact with each other and are configured to place the rotary latch in an overstroke closed position relative to the locking pawl in the closing direction. Specifically, the rotary latch is positioned in the closing direction beyond the pre-locking and master-locking positions of the rotary latch and locking pawl relative to each other, entering an overstroke closed position relative to the locking pawl, in which the locking pawl disengages from the rotary latch. In this case, the rotary latch can be held or secured in the overstroke closed position by the self-locking engagement of the tensioning rod and the drive mechanism. This enables a simple closing process assisted by an electric motor. Furthermore, the tensioning mechanism can be configured to hold the rotary latch in the overstroke closed position during vehicle travel. Therefore, a reverse process is reliably avoided. In other words, no reverse process is required after the opening operation of the locking mechanism. Therefore, due to the overstroke closed position during travel, movable vehicle components, such as flaps, engine hoods, etc., are positioned flush with, for example, the radial or surface-level area between the flaps and the vehicle body. In this case, the rotary latch can be set, for example, with a predetermined overstroke setting, such as in the millimeter range, particularly in the range of greater than 1 mm and less than 10 mm, to such an overstroke closed position, in which the seal is applied or can be applied with the nominal maximum sealing back pressure during vehicle travel.

[0011] Furthermore, the tensioning mechanism and the drive mechanism can interact with each other and can be configured to place the locking pawl in an overstroke open position relative to the rotary latch in the opening direction. This enables a simple opening operation assisted by an electric motor. This avoids the reverse process. In this case, in the overstroke open position, the locking pawl disengages from the rotary latch and is secured by means of a control element (e.g., a pressure rod). In this way, the drive mechanism can be initiated, while the rotary latch can be identified as open. With further drive opening, the drive mechanism skips the control element. In this case, the locking pawl disengages from the control element and returns to and enters a self-locking engagement, particularly a releasable locking engagement, preferably at the rotary latch, especially at the rotary latch shoulder and / or at the tensioning mechanism, particularly at the tensioning rod, for the open position of the locking mechanism.

[0012] Furthermore, the drive mechanism can preferably be configured as a single-motor drive, which is set to reverse the direction of rotation so that the locking mechanism is opened and closed by the motor. Therefore, the second drive can be omitted. Additionally, the single-motor drive can be configured as a synchronous motor. In particular, the drive mechanism may include a motor and a driven wheel that is directly or indirectly kinematically coupled to the locking mechanism via gears.

[0013] For example, the driven wheel may include a release profile and a close profile.

[0014] For example, the tensioning mechanism may include a tension profile and a tensioning rod. The tension profile and the tensioning rod may be in a self-locking engagement with each other, particularly in the overstroke closed position. In the overstroke open position, the tensioning rod and the locking pawl may be in a self-locking engagement with each other.

[0015] The tension profile can preferably be configured as a closing profile on the drive wheel. The tension rod can be arranged torsionally on the rotary latch. In other words, when the tension rod is actuated, the rotary latch is actuated, particularly pivoted, or conversely, when the tension rod is moved, particularly pivoted, the rotary latch also moves, particularly pivoted.

[0016] In addition, a control element pivotally supported on the locking pawl can be provided. The control element is specifically designed to secure the locking pawl and release its position to its overstroke open position. For example, the control element can be configured as a pressure bar. Specifically, the control element is pre-tensioned by means of a tension spring.

[0017] In addition, the locking pawl may include a stop profile, on which the stop surface of the control element abuts or rests during the opening operation and is fixed / positioned.

[0018] Furthermore, the locking device may include a control element configured to engage and / or disengage the locking pawl in the overstroke open position. For example, the control element may be configured as a pressure bar or a control lever. The control element may be pivotally supported, for example, in a limited manner. In particular, the control element is arranged and supported on the locking pawl, especially rotatably supported. Specifically, the control element is rotatably supported on the locking pawl so as to be followed. The control element may particularly be part of a tensioning mechanism and / or a locking mechanism.

[0019] The vehicle component according to the invention includes the locking device described above. Attached Figure Description

[0021] The same parts in all the accompanying drawings are indicated by the same reference numerals. Detailed Implementation

[0022] Figure 1 A perspective view of a vehicle 1 having a movable vehicle element 1.1 is schematically shown, which can be locked to the vehicle 1 by means of a locking device 2, particularly to the vehicle structure, vehicle body, or another vehicle component. In this case, the locking device 2 can be arranged on the movable vehicle element 1.1 or on the body of the vehicle 1 (as shown).

[0023] Movable vehicle components 1.1 include, for example, tailgates or doors, engine hoods, etc. Another vehicle component is, for example, the vehicle body.

[0024] The locking device 2 is configured as a tension lock. The locking device 2 includes at least one drive mechanism 4, a locking mechanism 6, and a tensioning mechanism 8 (such as...). Figure 2 (As shown).

[0025] The locking device 2 includes a lock housing 10. The locking device 2 is fastened or can be fastened to the vehicle component 1.1 by means of the lock housing 10 via a coupling interface 10.3, particularly a through hole for screw or rivet connection. The lock housing 10 is composed of several parts. The lock housing 10 includes, for example, a housing bracket 10.1 and a housing cover 10.2. In the assembled state of the lock housing 10, the locking mechanism 6 and the tensioning mechanism 8 are protectively arranged within the lock housing 10.

[0026] The drive mechanism 4 includes a driver 4.1 having a motor 4.2 and a driven wheel 4.3, which are protectively arranged within the lock housing 10. The drive mechanism 4 can preferably be configured as a single-motor driver, set to reverse the direction of rotation to open and close the lock mechanism 6 by the motor. Therefore, a second driver can be omitted. Furthermore, the single-motor driver can be configured as a synchronous motor. In particular, the drive mechanism 4 may include a spindle driver having a motor 4.2 and a drive spindle, the drive spindle being kinematically coupled to the lock mechanism 6 via gears, particularly via the driven wheel 4.3.

[0027] The lock housing 10 has a continuous groove 10.4 (also called an inlet groove) in which a closing element 13 (also called a reverse locking portion) can be arranged when the locking mechanism 6 is open and the movable vehicle element 1.1 is closed. The closing element 13 is locked by the closing of the locking mechanism 6, in particular by the engagement of the rotating latch 6.1 around the closing element 13.

[0028] The closing element 13 is, for example, a locking bracket or locking bolt held on the vehicle structure on the vehicle side.

[0029] In addition, a manual actuation mechanism 12, particularly a Bolton cable, can be provided for manually actuating the locking device 2, particularly the locking mechanism 6, optionally having a reset mechanism 14, particularly a reset spring.

[0030] Figure 2 The locking device 2 in the open position is shown schematically in a plan view, thus in the open position 100 of the locking mechanism 6, and in particular in the overstroke open position 106 of the tensioning mechanism 8. For clarity, the locking mechanism 6, the drive mechanism 4 and the tensioning mechanism 8, which are integrated into the lock housing 10, are shown in detail without the lock housing 10.

[0031] The locking device 2 is configured as a tension lock and includes a locking mechanism 6 having a rotary latch 6.1 and a locking pawl 6.2. The drive mechanism 4 is operatively coupled to the locking mechanism 6 to move it from the closed position 102 (as shown in the image). Figure 5 (As shown) Place it, in particular, open the open position 100, or place it from the open position 100 to, in particular, close the closed position 102.

[0032] The tensioning mechanism 8 is configured to, by means of the drive mechanism 4, overstroke the locking mechanism 6 in the closing direction 200 to place it in the overstroke closed position 104 (e.g., ...). Figure 6 As shown), and in the opening direction 202, it is placed in the overstroke opening position 106 with an overstroke (as shown). Figure 11 (As shown).

[0033] The locking mechanism 6 includes a rotary latch 6.1 and a locking pawl 6.2. The locking mechanism 6 also includes a master latch 6.3 and a pre-latch latch 6.4.

[0034] Rotary latch 6.1 is rotatable about a first rotation axis 300 between an open position 100 and a closed position 102 (also referred to as the closed position). Locking pawl 6.2 engages with rotary latch 6.1 in its closed position 102 to lock closing element 13 (such as...). Figure 1 (As shown). The locking pawl 6.2 can be released from the rotary latch 6.1. The locking pawl 6.2 can rotate about the second rotation axis 302. Through the interaction of the locking pawl 6.2 with the main latch 6.3 and the pre-latch 6.4, the rotary latch 6.1 is prevented in the closed position 102 and the main latch position 110 (as shown). Figure 5 and 9 (as shown) or in the middle position, especially in the pre-card lock position 108 (as shown) Figure 4 Rotate to the open position 100 (as shown).

[0035] During the closing operation by the electric motor, the tensioning mechanism 8 and the drive mechanism 4 interact with each other and are configured to place the rotary latch 6.1 in the overstroke closing position 104 relative to the closing direction 200 of the locking pawl 6.2, as shown. Figure 6 As shown.

[0036] Furthermore, the tensioning mechanism 8 can be configured to keep the rotary latch 6.1 in the overstroke closed position 104 during vehicle 1 operation. Therefore, reverse operation is reliably avoided.

[0037] Due to the overstroke closing position 104 during operation (e.g.) Figure 6 As shown), movable vehicle components 1.1, such as flaps, engine hoods, etc., are adjusted to be straight and flush and to maintain low noise. In this case, the rotary latch 6.1 can be set, for example, with a predetermined overstroke setting, for example in the millimeter range, particularly in the range greater than 1 mm and less than 10 mm, to such an overstroke closed position 104, in which the seal is applied or can be applied with a nominal maximum sealing back pressure during vehicle 1 travel.

[0038] Furthermore, the tensioning mechanism 8 and the drive mechanism 4 can interact during the opening operation by the electric motor, and can be configured to position the locking pawl 6.2 in the overstroke opening position 106 relative to the rotary latch 6.1 in the opening direction 202 (e.g., Figure 11 (As shown). This also avoids the reverse process.

[0039] The drive mechanism 4 includes a driven wheel 4.3. The driven wheel 4.3 includes a release profile 4.3.1 and a closing profile 4.3.2. The driven wheel 4.3 is rotatably supported in the lock housing 10 about a third rotation axis 303.

[0040] For example, the tensioning mechanism 8 may include a tension profile 8.1 and a tension rod 8.2. The tension profile 8.1 is specifically configured to close the profile 4.3.2 on the driven wheel 4.3. The tension rod 8.2 may be arranged torsionally on the rotary latch 6.1. The tension rod 8.2 and the rotary latch 6.1 may rotate together about a first axis of rotation 300. In other words, when the tension rod 8.2 is actuated in the closing direction 200 by means of the tension profile 8.1, the rotary latch 6.1 is actuated, in particular, pivoted, and engaged in a locking manner with the closing element 13. Conversely, when the rotary latch 6.1 moves from the closed position 102 in the opening direction 200, in particular, pivots, the tension rod 8.2 also moves, in particular, pivots, so that it then moves to the overstroke open position 106 (as shown in the image). Figure 1 , 11 (As shown) Engages with the pre-lock 6.4.

[0041] The tension profile 8.1 and the tension rod 8.2 can be in a self-locking engagement with each other, especially in the overstroke closed position 104 (e.g. Figure 6 As shown). In the overstroke open position 106 (as shown). Figure 1 , 11 As shown), the tensioning rod 8.2 and the locking pawl 6.2, especially the pre-locking lock 6.4, can be in a self-locking engagement with each other.

[0042] Furthermore, a control element 18 may be provided, particularly configured as a pressure lever or control lever. The control element 18 is pivotally supported on the locking pawl 6.2, particularly on its main latch 6.3, about a fourth axis of rotation 304. The control element 18 is specifically used to secure the locking pawl 6.2 and release the position of the locking pawl 6.2 to its overstroke open position 106. For example, the control element 18 may be configured as a pressure lever. In particular, the control element 18 may be pre-tensioned by means of a tension spring 18.1.

[0043] Furthermore, the locking pawl 6.2, particularly the pre-locking lock 6.4, may include a stop profile 6.5, on which the stop surface 18.2 of the control element 18 abuts and is secured during the opening operation.

[0044] Furthermore, the locking device 2 may include two switching elements 20, by means of which the locking positions of, for example, the main locking 6.3 and the pre-locking 6.4 are monitored and detected. A third switching element 21 may be omitted, for example, on the drive wheel 4.3, for the zero or intermediate position. The two switching elements 20 may be configured as microswitches, for example. The locking device 2 requires only two switching elements 20. In the open position 100, the two switching elements 20 are actuated by the positions of the main locking 6.3 and the pre-locking 6.4.

[0045] The locking device 2, configured as a pull-lock, can be fastened to the vehicle body side or flap side, and then engages with the closing element 13 (reverse locking portion) on the flap side or vehicle body side. The lock housing 10 has a slot 10.4 for the closing element 13 (e.g., Figure 1 (As shown) serves as the inlet slot. The fork 6.1.1 of the rotary latch 6.1 opens in the slot 10.4 in the overstroke open position 104 and open position 100 of the rotary latch 6.1 in such a way that the closing element 13 can enter the fork 6.1.1.

[0046] The open position 100 is understood as the open position of the locking mechanism 6, wherein the closing element 13 has disengaged from the rotary latch 6.1. The invention provides that, in the open position, the locking pawl 6.2 does not engage with the rotary latch 6.1. Instead, the locking pawl 6.2 remains engaged with the tension rod 8.2. This form-locking and force-locking, releasable engagement is referred to as the overstroke open position 106 (= first overstroke position) of the locking pawl 6.2. The overstroke open position 106 represents the overstroke position of the locking pawl 6.2 relative to the rotary latch 6.1.

[0047] Figure 3 The plan view schematically illustrates the situation at the start of the tensioning operation according to... Figure 2 The locking device 2. Two switching elements 20 are closed or optionally opened in the overtravel position 106 of the locking pawl 6.2, thus affecting the locking pawl 6.2 and the locking mechanism 6 (as shown in the image). Figure 2 The same applies to the open position 100 (as shown).

[0048] In order to initiate a closing or tightening operation assisted by an electric motor, the first switching element 20.1 of the pre-lock 6.4 is switched and opened.

[0049] like Figure 3 As shown, in particular, by manually actuating the movable vehicle element 101, the locking device 2 moves from the overstroke position 106, thereby moving from the open position 100 (as shown). Figure 2 (As shown) Move to the pre-lock position 108.

[0050] In this case, shut down component 13 (such as Figure 1(As shown) Enters the fork 6.1.1. The rotary latch 6.1 first moves back to the pre-lock position 108 according to the closing direction 200 at the locking pawl 6.2. As a result, the tension rod 8.2, which is torsionally supported on the rotary latch 6.1, disengages from the engagement of the locking pawl 6.2, thereby disengaging the locking pawl 6.2 from the overstroke open position 106 on the tension rod 8.2 (as shown). Figure 2 (As shown).

[0051] Driven wheel 4.3 is driven by an electric motor and moves clockwise, for example, according to arrow 400. Release profile 4.3.1 is adjacent to and follows control element 18. Figure 3 As shown, control element 18 moves in the opposite direction according to arrow 402, for example, counterclockwise, until release profile 4.3.1 skips control element 18, specifically a spring-loaded lever that automatically resets, particularly spring-driven. For this purpose, a reset spring (not shown) is arranged on control element 18.

[0052] When the driven wheel 4.3 is further actuated as indicated by arrow 400, the closing profile 4.3.2 is configured to tension profile 8.1 on the drive wheel 4.3, adjacent to tensioning rod 8.2, which is torsionally coupled to rotary latch 6.1.

[0053] Figure 4 Another plan view of the locking device 1 is schematically shown, wherein the driven wheel 4.3 is in the position from the pre-lock position 108 to the main lock position 110 (e.g., Figure 5 (As shown) is further actuated during the tightening process.

[0054] When the driven wheel 4.3 is further actuated, as indicated by arrow 400, only the drive is adjusted. The closing profile 4.3.2, configured as a tension profile 8.1 on the driven wheel 4.3, is also adjacent to the tension rod 8.2, which is torsionally coupled to the rotary latch 6.1, wherein the rotary latch 6.1 is held in a pre-lock position 108 at the pre-lock 6.4 by means of the tension profile 8.1 and the tension rod 8.2, as... Figure 4 As shown.

[0055] In the pre-lock position 108, the locking surface 6.1.2 of the rotary latch 6.1 abuts or engages the reverse locking surface 6.4.1 of the pre-lock 6.4 of the locking pawl 6.2. By moving the rotary latch 6.1, the locking mechanism 6 moves from the pre-lock position 108 to the main lock position 110, as... Figure 5 As shown.

[0056] The start of the tensioning process is independent of the closing speed, especially through the drive mechanism 4 (such as...). Figure 1As shown), especially the rapid closure of the spindle drive. The tightening process only begins when the signal of the first switching element 20.1 changes. The rotational position of the pre-lock 6.4 and the rotation latch 6.1 in the open position 100 are detected by the first switching element 20.1. For this purpose, the first switching element 20.1 can use the first sensing lug 20.1.1 to sense, for example, the control curve of the pre-lock 6.4. Once the pre-lock position 108 is reached (as shown), the tightening process begins. Figure 3 and 4 As shown), that is, when the pre-lock 6.4 is in the rotary latch 6.1, the first sensing lug 20.1.1 loses its contact and enters the non-actuated state.

[0057] Electric motor 4.2 (e.g.) Figure 1 (As shown) After reaching the pre-lock position 108, it moves further and applies driving force to the driven wheel 43 by releasing profile 4.3.1 and closing profile 4.3.2, wherein the driven wheel 43 moves further according to arrow 400.

[0058] In this configuration, the closing profile 4.3.2, configured as the tension profile 8.1, further abuts the tension rod 8.2 on the driven wheel 4.3, which is torsionally coupled to the rotary latch 6.1, such that the rotary latch 6.1 rotates from the pre-lock position 108 to the main lock position 110 according to arrow 404 by means of the tension profile 8.1 and the tension rod 8.2, corresponding to the closed position 102 of the locking device 2. Figure 5 As shown.

[0059] The functional position of the tensioning lever 8.2 is determined by the second switching element 20.2. This second switching element 20.2 also has a second sensing lug 20.2.1, which engages with the control cam of the tensioning lever 8.2 and / or the main locking mechanism 6.3. In this example, the second sensing lug 20.2.1 loses contact with the main locking mechanism 6.3, specifically with the control cam on the main locking mechanism 6.3. In this case, the second switching element 20.1 switches from an actuated state (=1) to a deacted state (=0).

[0060] The rotary latch 6.1 and the locking pawl 6.2 are located in the main latch position 110, corresponding to the closed position 102 of the locking device 2.

[0061] The two switching elements 20.1 and 20.2 are electrically configured as push buttons because they remain in the ON state only under permanent pressure on the associated sensing lugs 20.1.1 and 20.2.1, and change to the OFF state after the force is removed.

[0062] With further rotation of the driven wheel 4.3, according to arrow 400, the rotary latch 6.1 is placed in the overstroke closed position 104 in the closing direction 200 via the follower coupling of the tension profile 8.1 and the tension rod 8.2, as shown. Figure 6 As shown.

[0063] Figure 6 Another plan view schematically illustrates the locking device 2 in the overstroke closed position 104 of the rotary latch 6.1. This overstroke closed position 104 of the rotary latch 6.1 remains unchanged during operation. The overstroke closed position 104 represents the overstroke position of the rotary latch 6.1 relative to the locking pawl 6.2. The end position of the rotary latch 6.1 in the overstroke closed position 104 (also referred to as the drive position), which is also the closed position 102 (also referred to as the closed position), can be provided to the central controller, for example, via block current detection, to deactivate the drive mechanism 4, particularly the motor 4.2.

[0064] Figure 7 The plan view schematically shows the locking device 2 in the overstroke closed position 104 and the operation initiated by rotating the driven wheel 4.3 according to arrow 406. The two switching elements 20.1 and 20.2 are deactivated.

[0065] In the overstroke closed position 104, the rotary latch 6.1 is supported on the main latch 6.3 and the locking pawl 6.2, preventing the rotary latch 6.1 from rotating to the open position 100. The tension profile 8.1 and the tension rod 8.2 are in a self-locking engagement 22, particularly in a releasable locking engagement. The control element 18 is separately constructed and can be rotatably supported on the locking pawl 6.2, particularly on the pre-lock 6.4. The pre-lock 6.4 has a stop profile 6.5 for the control element 18.

[0066] The driven wheel 4.3 has an open profile 4.3.3. The open profile 4.3.3 can be in the form of a projecting arm.

[0067] By issuing the signal, motor 4.2 moves driven wheel 4.3 according to arrow 406, resulting in the opening profile 4.3.3 moving according to arrow 408, as... Figure 8 As shown.

[0068] Figure 8 Another plan view of the locking device 2 is schematically shown during the opening operation from the overstroke closed position 104 to the closed position 102 by the controlled lowering of the rotating latch 6.1 according to arrow 408.

[0069] In this case, the tension profile 8.1 and the tension rod 8.2 disengage from their self-locking engagement 22 (as shown). Figure 7As shown), this allows the rotary latch 6.1 to move further in the opening direction 202 according to arrow 408.

[0070] like Figure 9 As shown, by rotating the driven wheel 4.3 as indicated by arrow 406, the opening profile 4.3.3 reaches the follower engagement 24 on the control element 18.

[0071] Figure 9 Another plan view schematically illustrates the locking device 2 during the opening operation in the opening direction 202 and during the disengagement of the rotary latch 6.1 and locking pawl 6.2 from the main latch position 110 and the pre-latch position 108 to the open position 100, as shown. Figure 10 As shown. During the opening operation of the rotary latch 6.1 and locking pawl 6.2, by rotating the driven wheel 4.3 as indicated by arrow 406, the two switching elements 20.1 and 20.2 are actuated again and switched from "0" to "1". This is achieved by controlling the control detected as the open position 100 of the rotary latch 6.1, and simultaneously detecting the drive mechanism 4 (as shown in the image). Figure 2 The startup initialization (as shown) is performed so that the rotary latch 6.1 is positioned as shown by arrow 410, and the locking pawl 6.2 is positioned as shown by arrow 412 into the overstroke open position 106. Figure 11 As shown.

[0072] Figure 10 Another plan view of the locking device 2 during the opening operation is schematically shown, wherein the control element 18 is fixed to the locking pawl 6.2, particularly on the stop profile 6.5 in the open position 100 of the locking mechanism 6 and the overstroke open position 106 of the locking pawl 6.2. The control element 18 is configured to fix the locking pawl 6.2 in the overstroke open position 106. The opening profile 4.3.3 skips the control element 18, which is configured as a pressure bar or control lever. In this case, the locking pawl 6.2 is released and rotated back, and enters another self-locking engagement 26, particularly a releasable locking engagement, on the shoulder of the rotary latch 6.1 and / or the tensioning bar 8.2, for the open position 100, as... Figure 11 As shown.

[0073] Figure 11 It is shown in accordance with Figure 10 The locking pawl 6.2 is in the overstroke open position 106 after the locking device 2 is in the open position 100 of the locking mechanism 6.

[0074] According to Figure 10In the overstroke open position 106, the locking pawl 6.2 is fully raised. By skipping the control element 18, the locking pawl 6.2 engages in a further self-locking engagement 26 at the open rotary latch 6.1, and optionally engages the tension rod 8.2 at the open rotary latch 6.1. The locking mechanism 6 is again in the open position 100. In this case, the rotary latch 6.1 / optionally the tension rod 8.2 and the locking pawl 6.2, particularly the pre-locking lock 6.4, in this further self-locking engagement 26, releasably lock the rotary latch 6.1 in the open position 100.

[0075] according to Figure 10 The overstroke open position 106 of the locking pawl 6.2 is detected by the tension rod 8.2 and the open position 100 with the self-locking engagement 26 as the end position of the actuator 4 or as time passes during the opening operation.
