Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism and a closing / opening device, which has at least one drive and a lever drive.
- the closing / opening device operates on the locking mechanism either in a pulling or in an opening direction. Serves the drive, which is regularly applied, for example, when pulling in when an associated motor vehicle door is in its Vorrastwolf. Then the drive including the closing device ensures that the motor vehicle door is transferred from its pre-locking position or prelocking position into a main closed position or main locked position of the associated door lock.
- opening aids are also known, which also rely on a drive and support issuing an associated motor vehicle door or a tailgate. Such opening aids also take into account the increased weight of the vehicle doors or flaps and increase comfort.
- the invention is based on the technical problem of further developing such a motor vehicle door lock that, with a simple and cost-effective construction, the operating forces are significantly reduced, in particular when the closing movement is interrupted.
- This lock operating lever may be an inside operating lever, an outside operating lever or a so-called operating main lever. Both the internal operating lever work as well as the external operating lever on such a main operating lever.
- the design according to the invention ensures that an action on the lock operating lever (inner operating lever, outer operating lever, actuating main lever) acts directly on the trigger lever or ejector lever.
- the fact that the release lever or ejector lever is acted upon, the mechanical operative connection between the drive and the locking mechanism is interrupted immediately.
- the release lever or ejector lever works on the lever drive in such a way that it is transferred from its engaged position to the disengaged position. In the disengaged position is released simultaneously and possibly the locking mechanism.
- a closing movement of the closing / opening device according to the invention can be interrupted at any time without problems and with little force and, in the example, set up the associated motor vehicle door.
- an operator only has to work with the help of the lock actuating lever on the release lever or ejector lever, which in turn transfers the lever drive from its engaged position to the disengaged position. This can be done with extremely low operating forces and can be implemented quickly. So if, for example, a child has clamped his hand during the closing process in the vehicle door, even its operating forces are sufficient to disengage the lever drive directly and release the locking mechanism, if necessary, to stop the closing process.
- the closing movement is interrupted immediately and the associated motor vehicle door due to the released locking mechanism either from the outside or from the inside can be easily opened - if previously provided for unlocking.
- the interruption of the lever drive succeeds using the lock operating lever to open the locking mechanism both from the inside and the outside.
- the lock operating lever is the inside operating lever and / or the outside operating lever or an operating main lever on which both the inside operating lever and the outside operating lever work.
- the inside operating lever is mechanically connected to an inside door handle, while an outside door handle works on the outside operating lever.
- both pawls that is to say the drive pawl and the latching pawl, are mounted together and preferably off-axis on an actuating element or actuating lever.
- This actuator is acted upon by the drive.
- the drive regularly has an eccentric, which acts on the actuating element or the actuating lever. Because of this eccentric solution, the drive can be reversibly returned to its starting position after, for example, the closing process, without the actuating lever following it.
- the design is such that it works regularly on the latch. This ensures that the pawl blocks the drive pawl in the engaged position of the lever drive and releases in the disengaged position of the lever drive. Because the movement of the drive is transmitted via the eccentric to the actuated by him actuator, the drive pawl can only work on the ratchet when the pawl blocks the drive pawl in the engaged position of the lever drive. Only in this case attacks the lever drive and thus the drive pawl on a pin of the locking mechanism. In most cases, the pin is located on a catch of the locking mechanism and serves to its transfer from the prelocking in the main closed position.
- the drive pawl may yield to the ratchet as compared to said peg and release the ratchet from the lever drive and thus the entire closing / opening device.
- the drive pawl is further and advantageously equipped with a so-called pruning. That is, the lever drive has according to a preferred embodiment in the region of its contact surface on the locking mechanism via a precut. In this way, in the direction of "open" spring-loaded locking mechanism is able to issue immediately the disengaged lever drive. That is, the pre-cut realized on the drive pawl of the lever drive assists the deployment movement of the drive pawl as soon as it is no longer held in position by means of the latching pawl. This is the case immediately after applying the latch with the help of the release lever or ejector lever. Through this, as it were, automatism and the exploitation of the Any existing force of the spring of the locking mechanism for taking the disengaged position of the lever drive, the operating force on the lock operating lever is significantly reduced.
- the actuating lever or the actuating element is designed to open the locking mechanism as a one-sided bearing Einarmhebel and optionally cranked.
- the eccentric provided on the drive can easily act on the said actuating lever at its free end.
- the actuating lever in question is mounted coaxially to the catch of the locking mechanism, so that a particularly compact and cost-effective construction is achieved.
- this design ensures that the drive can be mounted with the eccentric immediately above the locking mechanism or the catch and can thus be used in very narrow motor vehicle door locks.
- a motor vehicle door lock is shown, which is composed as usual of a mainly shown motor vehicle door lock 1 and a merely indicated locking pin 2.
- the locking bolt 2 is regularly fastened to an associated motor vehicle body, while the motor vehicle door lock 1 experiences a fixation on a motor vehicle door not expressly shown.
- the motor vehicle door lock or the motor vehicle door lock 1 is equipped with a conventional locking mechanism 3, 4 of rotary latch 3 and pawl 4.
- the motor vehicle door lock has a closing / opening device 5 to 12, which in the present case is configured as a closing aid 5 to 12.
- the closing / opening device 5 to 12 is equipped with at least one drive 5, 6, 7, 8, 9 and a lever drive 10, 11, 12.
- the drive 5, 6, 7, 8, 9 is composed of a motor or electric motor 5 and a drive screw 6 which is mounted on a drive shaft provided on the output side of the drive 5 and is rotated by means of the motor 5 in rotation.
- Rotations of the drive worm 6 cause a worm wheel 7 meshing therewith, depending on the direction of rotation of the reversing motor or electric motor, to perform 5 clockwise or counterclockwise rotations, as shown by a double arrow in FIG Fig. 1 suggests.
- the pin 9 of the drive 5, 6, 7, 8, 9 abuts against an actuating lever or actuating element 10 of the lever drive 10, 11, 12.
- the actuating lever 10 is presently designed as a Einarmhebel and mounted with its one end coaxially in comparison to the rotary latch 3. That is, the rotary latch 3 and the operating lever 10 have the same axis of rotation.
- the drive 5, 6, 7, 8, 9 engages with the eccentric 8 and the pin 9 and acts on this free end.
- the lever drive 10, 11, 12 as essential components on two pawls 11, 12, namely a drive pawl 11 and a latch 12. Both the drive pawl 11 and the latch 12 are mounted on the actuating lever 10, and that together and mutually out of sorts.
- this lock operating lever 15 is an external operating lever in the example case, which is mechanically connected to an outside door handle.
- the release lever or ejector lever 14 may also be connected to an internal operating lever or an actuating main lever of the motor vehicle door lock.
- the inside operating lever is operatively connected to a door inside handle.
- the actuating main lever may be acted upon by both the door inner handle and the outside door handle and is mechanically connected to this, which is not shown.
- the operation is as follows. Starting from the "open" position of the locking mechanism 3, 4 or the catch 3 in the Fig. 1 An operator initially moves the motor vehicle door into the pre-closing position or pre-locking position Fig. 2 , For this purpose, the locking pin 2 engages in an associated inlet mouth of the rotary latch 3 in a conventional manner and pivots them in the example shown in the counterclockwise direction until the pre-locking position after Fig. 2 is reached.
- This pre-locking position or prelocking position can be sensed, for example, and causes the motor 5 to start running immediately thereafter.
- the direction of rotation of the motor 5 is set so that the acted upon by him worm 7 at the transition from the Fig. 2 to Fig. 3 the further described in about a quarter turn counterclockwise performs.
- the pin 9 of the eccentric 8 abuts on the actuating lever 10 of the lever drive 10, 11, 12 and at the same time ensures the equipped with their contact surface 11a driving pawl 11 that the catch 3 and therefore the locking mechanism 3, 4 total in the main position is transferred.
- the contact surface 11a interacts with the described closing process with the pin 13 on the rotary latch 3, so that the drive 5, 6, 7, 8, 9 initiated pivotal movement of the actuating lever 10 in the counterclockwise direction at the same time to a likewise pivotal movement in the counterclockwise direction on the rotary latch 3 corresponds.
- the swept by the operating lever 10 swivel angle is formed smaller due to its bend than the swept by the rotary latch 3 swivel angle.
- the drive pawl 11 is arranged radially inwardly relative to the pin 9 of the eccentric 8 with respect to the axis of rotation of the actuating lever 10.
- the detent pawl 12 in total ensures that the lever drive 10, 11, 12 remains in its engaged state. Because in this state or the engaged position of the lever drive 10, 11, 12 ensures a mechanical operative connection between the drive 5, 6, 7, 8, 9 and the locking mechanism 3, 4. That is, the latch 12 holds the drive pawl 11th with its contact surface 11 a in contact with the pin 13 of the rotary latch. 3
- this emergency interruption is initiated in the example case in that an operator pulling the outer actuating lever 15 in the direction of arrow Fig. 3 applied.
- the triggering lever or ejector lever 14 which interacts with the external actuating lever 15, acts on the latching pawl 12 in such a way that it is pivoted about its axis mounted on the actuating lever 10 in the clockwise direction.
- the drive pawl 11 is equipped with a pre-cut on its stop surface 11a facing the ratchet 3, 4 or the pin 13 there, as the enlarged illustration in FIG Fig. 3 makes it clear.
- This pre-cut or bevel causes a force acting on the drive pawl 11 from the pin 13, the drive pawl 11 pivots away from the pin 13 in a clockwise direction.
- the locking mechanism 3, 4 is released immediately, which of course also applies to the locking pin 2 when the motor vehicle door lock 1 is in the "unlocked” state. Otherwise, that is in the "locked” position, the locking mechanism 3, 4 goes back to the prelocking or pre-locked position. In any case, the closing function is interrupted. In most cases, however, the motor vehicle door lock 1 is unlocked at the same time.
- the motor vehicle door associated with the motor vehicle door lock 1 can accordingly be opened directly, or the drive 5, 6, 7, 8, 9 is empty with reference to the closing function.
- the locking mechanism 3, 4 either goes to the pre-locked position Fig. 2 back (when the vehicle door lock 1 remains unchanged in its "locked” position) or the locking mechanism 3, 4 is released altogether and goes to the "open” position Fig. 1 over when the vehicle door lock 1 is unlocked or has already been unlocked.
- the entire drive 5, 6, 7, 8, 9 does not necessarily have to be integrated into the motor vehicle door lock 1 as shown. It is basically also possible that the drive 5, 6, 7, 8, 9 is realized locally independently of the motor vehicle door lock 1 and produces with this example, a connection via a Bowden cable.
- the actuating lever 10 is no longer predominantly S-shaped configured, but has an additional connecting web 10a in the region of the lower S-arm.
- a control lever 16 is arranged respectively mounted on the actuating lever 10. This control lever 16 occurs to the two unchanged on the operating lever 10 mounted pawls, on the one hand the drive pawl 11 and on the other hand, the latch 12 is added.
- the control lever 16 serves to bring the drive pawl 11 with the catch 3 into engagement.
- the control lever 16 actuates the drive pawl 11 as soon as the catch 3 has reached the pre-locked position and the drive 5,6,7,8,9 has been turned on.
- the control lever 16 is controlled by the eccentric 8.9. Only when the drive pawl 11 is coupled to the rotary latch 3, the closing process begins.
- An advantage of the control lever 16 is the avoidance of an unwanted collision of drive pawl 11 and transmission lever 10 with the rotary latch 3, when the drive pawl 11 or, as in the erfingsdorfen solution, is not controlled directly from the eccentric 8.9.
- the control of the control lever 16 can, as in Fig. 4 represented by the contour of the eccentric 8.9, which also drives the transmission lever 10.
- the control lever it is also possible within the scope of the invention for the control lever to be actuated by a second control contour of the eccentric 8, 9 which is not shown in the figures.

Description
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit einem Gesperre sowie einer Zuzieh-/Öffnungseinrichtung, welche wenigstens einen Antrieb und einen Hebeltrieb aufweist.The invention relates to a motor vehicle door lock, with a locking mechanism and a closing / opening device, which has at least one drive and a lever drive.
Die Zuzieh-/Öffnungseinrichtung arbeitet auf das Gesperre entweder in zuziehendem oder in öffnendem Sinne. Dazu dient der Antrieb, welcher regelmäßig beispielsweise beim Zuziehen dann beaufschlagt wird, wenn sich eine zugehörige Kraftfahrzeugtür in ihrer Vorraststellung befindet. Dann sorgt der Antrieb inklusive der Zuzieheinrichtung dafür, dass die Kraftfahrzeugtür von ihrer Vorraststellung bzw. Vorschließstellung in eine Hauptschließstellung bzw. Hauptraststellung des zugehörigen Türschlosses überführt wird.The closing / opening device operates on the locking mechanism either in a pulling or in an opening direction. Serves the drive, which is regularly applied, for example, when pulling in when an associated motor vehicle door is in its Vorraststellung. Then the drive including the closing device ensures that the motor vehicle door is transferred from its pre-locking position or prelocking position into a main closed position or main locked position of the associated door lock.
Solche Zuzieheinrichtungen oder Zuziehhilfen kommen momentan und überwiegend bei hochpreisigen und exklusiven Kraftfahrzeugen zum Einsatz, weil Sie mit zusätzlichem mechanischen und folglich kostenmäßigen Aufwand verbunden sind. Außerdem zeichnen sich derartige Automobile oftmals durch ein zunehmendes Gewicht der zugehörigen Kraftfahrzeugtür aus, welches unter anderem ergänzenden Einbauten wie Seitenairbags, Verstärkungen etc. oder auch elektrischen Einbauten wie Lautsprechern geschuldet ist. Jedenfalls erhöhen Zuzieheinrichtungen den Komfort enorm und sind auch als Sicherheitsbauteil von besonderer Bedeutung. Denn sie stellen sicher, dass die zugehörige Kraftfahrzeugtür in jedem Fall in die Hauptschließstellung überführt wird, in welcher erst die heutzutage hohen Sicherheitsstandards im Falle eines Unfalls erreicht werden. Für die Vorschließstellung gilt dies nicht.Such Zuzieheinrichtungen or Zuziehhilfen are currently and predominantly used in high-priced and exclusive vehicles, because they are associated with additional mechanical and therefore costly effort. In addition, such automobiles are often distinguished by an increasing weight of the associated motor vehicle door, which among other things is due to supplementary installations such as side airbags, reinforcements, etc., or also electrical installations such as loudspeakers. In any case, Zuzieheinrichtungen increase the comfort enormously and are also as a security component of particular importance. Because they ensure that the associated motor vehicle door is transferred in any case in the main closed position, in which only the nowadays high safety standards in the event of an accident can be achieved. This does not apply to the pre-closing position.
Ganz abgesehen davon sind auch sogenannte Öffnungshilfen bekannt, welche ebenfalls auf einen Antrieb zurückgreifen und ein Ausstellen einer zugehörigen Kraftfahrzeugtür oder auch einer Heckklappe unterstützen. Solche Öffnungshilfen tragen ebenfalls dem erhöhten Gewicht der Kraftfahrzeugtüren bzw. -klappen Rechnung und erhöhen den Komfort.Quite apart from so-called opening aids are also known, which also rely on a drive and support issuing an associated motor vehicle door or a tailgate. Such opening aids also take into account the increased weight of the vehicle doors or flaps and increase comfort.
Bei einem Kraftfahrzeugtürverschluss der eingangs beschriebenen Ausgestaltung entsprechend der
Der Erfindung liegt das technische Problem zugrunde, einen derartigen Kraftfahrzeugtürverschluss so weiter zu entwickeln, dass bei einfachem und kostengünstigem Aufbau die Bedienkräfte insbesondere beim Unterbrechen der Zuziehbewegung deutlich reduziert sind.The invention is based on the technical problem of further developing such a motor vehicle door lock that, with a simple and cost-effective construction, the operating forces are significantly reduced, in particular when the closing movement is interrupted.
Zur Lösung dieser technischen Problemstellung ist bei einem gattungsgemäßen Kraftfahrzeugtürverschluss vorgesehen, dass der Hebeltrieb in seiner eingekuppelten Stellung eine mechanische Wirkverbindung zwischen dem Antrieb und dem Gesperre herstellt und mittels eines Auslösehebels in seine ausgekuppelte Stellung gegebenenfalls unter Freigabe des Gesperres überführt wird.To solve this technical problem is provided in a generic motor vehicle door lock that the lever drive in its engaged position produces a mechanical operative connection between the drive and the ratchet and is transferred by means of a release lever in its disengaged position optionally with the release of the locking mechanism.
Regelmäßig sorgt für die Beaufschlagung des Auslösehebels für den Hebeltrieb ein Schlossbetätigungshebel, der zum Öffnen des Gesperres dient. Das heißt, der Auslösehebel bzw. Auswerferhebel für den Hebeltrieb der Zuzieh-/Öffnungseinrichtung wechselwirkt mit dem besagten Schlossbetätigungshebel zum Öffnen des Gesperres. Bei diesem Schlossbetätigungshebel kann es sich um einen Innenbetätigungshebel, einen Außenbetätigungshebel oder auch einen sogenannten Betätigungshaupthebel handeln. Dabei arbeiten sowohl der Innenbetätigungshebel als auch der Außenbetätigungshebel auf einen solchen Betätigungshaupthebel.Regularly ensures the actuation of the release lever for the lever drive a lock operating lever, which serves to open the locking mechanism. That is, the trigger lever for the lever drive of the closing / opening device interacts with said lock operating lever to open the locking mechanism. This lock operating lever may be an inside operating lever, an outside operating lever or a so-called operating main lever. Both the internal operating lever work as well as the external operating lever on such a main operating lever.
In jedem Fall stellt die erfindungsgemäße Auslegung sicher, dass eine Beaufschlagung des Schlossbetätigungshebels (Innenbetätigungshebel, Außenbetätigungshebel, Betätigungshaupthebel) unmittelbar auf den Auslösehebel bzw. Auswerferhebel wirkt. Dadurch, dass der Auslösehebel bzw. Auswerferhebel beaufschlagt wird, wird die mechanische Wirkverbindung zwischen dem Antrieb und dem Gesperre augenblicklich unterbrochen.In any case, the design according to the invention ensures that an action on the lock operating lever (inner operating lever, outer operating lever, actuating main lever) acts directly on the trigger lever or ejector lever. The fact that the release lever or ejector lever is acted upon, the mechanical operative connection between the drive and the locking mechanism is interrupted immediately.
Hierzu arbeitet der Auslösehebel bzw. Auswerferhebel auf den Hebeltrieb dergestalt, dass dieser von seiner eingekuppelten Stellung in die ausgekuppelte Stellung überführt wird. In der ausgekuppelten Stellung wird gleichzeitig und gegebenenfalls das Gesperre freigegeben. Auf diese Weise lässt sich beispielsweise eine Zuziehbewegung der erfindungsgemäßen Zuzieh-/Öffnungseinrichtung jederzeit problemlos und mit geringen Kräften unterbrechen und im Beispielfall die zugehörige Kraftfahrzeugtür aufstellen. Denn hierzu muss ein Bediener lediglich mit Hilfe des Schlossbetätigungshebels auf den Auslösehebel bzw. Auswerferhebel arbeiten, der wiederum den Hebeltrieb von seiner eingekuppelten Stellung in die ausgekuppelte Stellung überführt. Das kann mit äußerst geringen Bedienkräften erfolgen und lässt sich reaktionsschnell realisieren. Wenn also beispielsweise ein Kind seine Hand beim Zuziehvorgang in der Kraftfahrzeugtür eingeklemmt hat, reichen selbst dessen Bedienkräfte aus, den Hebeltrieb unmittelbar auszukuppeln und das Gesperre gegebenenfalls freizugeben, auf jeden Fall den Zuziehvorgang zu stoppen.For this purpose, the release lever or ejector lever works on the lever drive in such a way that it is transferred from its engaged position to the disengaged position. In the disengaged position is released simultaneously and possibly the locking mechanism. In this way, for example, a closing movement of the closing / opening device according to the invention can be interrupted at any time without problems and with little force and, in the example, set up the associated motor vehicle door. For this purpose, an operator only has to work with the help of the lock actuating lever on the release lever or ejector lever, which in turn transfers the lever drive from its engaged position to the disengaged position. This can be done with extremely low operating forces and can be implemented quickly. So if, for example, a child has clamped his hand during the closing process in the vehicle door, even its operating forces are sufficient to disengage the lever drive directly and release the locking mechanism, if necessary, to stop the closing process.
Auf diese Weise wird die Zuziehbewegung augenblicklich unterbrochen und kann die zugehörige Kraftfahrzeugtür infolge des freigegebenen Gesperres entweder von außen oder von innen problemlos geöffnet werden - wenn zuvor für eine Entriegelung gesorgt wird. Dabei gelingt die Unterbrechung des Hebeltriebes mit Hilfe des Schlossbetätigungshebels zum Öffnen des Gesperres sowohl von innen als auch von außen. Denn bei dem Schlossbetätigungshebel handelt es sich um den Innenbetätigungshebel und/oder den Außenbetätigungshebel bzw. einen Betätigungshaupthebel, auf den sowohl der Innenbetätigungshebel als auch der Außenbetätigungshebel arbeiten. Dabei ist der Innenbetätigungshebel wie üblich mit einem Innentürgriff mechanisch verbunden, während ein Außentürgriff auf den Außenbetätigungshebel arbeitet.In this way, the closing movement is interrupted immediately and the associated motor vehicle door due to the released locking mechanism either from the outside or from the inside can be easily opened - if previously provided for unlocking. The interruption of the lever drive succeeds using the lock operating lever to open the locking mechanism both from the inside and the outside. For the lock operating lever is the inside operating lever and / or the outside operating lever or an operating main lever on which both the inside operating lever and the outside operating lever work. As usual, the inside operating lever is mechanically connected to an inside door handle, while an outside door handle works on the outside operating lever.
Hierin sind die wesentlichen Vorteile zu sehen.Here are the main benefits.
Es hat sich bewährt, wenn der vom Antrieb beaufschlagte und am Gesperre angreifende Hebeltrieb wenigstens zweiteilig ausgebildet ist. Meistens kommen eine Antriebsklinke und eine Rastklinke zum Einsatz. Dabei wird die Antriebsklinke mittelbar oder unmittelbar vom Antrieb beaufschlagt, wohingegen die Rastklinke dafür sorgt, dass die Antriebsklinke mit dem Gesperre wechselwirkt oder nicht.It has proven useful if the acted upon by the drive and engaging the locking lever drive is at least formed in two parts. Mostly a drive pawl and a latch are used. The drive pawl is indirectly or directly acted upon by the drive, whereas the latch ensures that the drive pawl interacts with the ratchet or not.
Im Allgemeinen sind beide Klinken, das heißt die Antriebsklinke und die Rastklinke, gemeinsam und vorzugsweise achsversetzt auf einem Betätigungselement bzw. Betätigungshebel gelagert. Dieses Betätigungselement wird von dem Antrieb beaufschlagt. Hierzu verfügt der Antrieb regelmäßig über einen Exzenter, welcher das Betätigungselement bzw. den Betätigungshebel beaufschlagt. Aufgrund dieser Exzenterlösung kann der Antrieb nach beispielsweise dem Zuziehvorgang reversierend wieder in seine Ausgangsposition zurück überführt werden, ohne dass ihm der Betätigungshebel hierbei folgt.In general, both pawls, that is to say the drive pawl and the latching pawl, are mounted together and preferably off-axis on an actuating element or actuating lever. This actuator is acted upon by the drive. For this purpose, the drive regularly has an eccentric, which acts on the actuating element or the actuating lever. Because of this eccentric solution, the drive can be reversibly returned to its starting position after, for example, the closing process, without the actuating lever following it.
Mit Blick auf den Auslösehebel bzw. Auswerferhebel ist die Auslegung so getroffen, dass dieser regelmäßig auf die Rastklinke arbeitet. Hierdurch wird gewährleistet, dass die Rastklinke die Antriebsklinke in eingekuppelter Stellung des Hebeltriebs blockiert und in ausgekuppelter Stellung des Hebeltriebs freigibt. Weil die Bewegung des Antriebes über den Exzenter auf das von ihm beaufschlagte Betätigungselement übertragen wird, kann die Antriebsklinke auf das Gesperre nur dann arbeiten, wenn die Rastklinke die Antriebsklinke in der eingekuppelten Stellung des Hebeltriebs blockiert. Nur in diesem Fall greift der Hebeltrieb und damit die Antriebsklinke an einem Zapfen des Gesperres an. Meistens findet sich der Zapfen an einer Drehfalle des Gesperres und dient zu dessen Überführung von der Vorschließstellung in die Hauptschließstellung.With regard to the release lever or ejector lever, the design is such that it works regularly on the latch. This ensures that the pawl blocks the drive pawl in the engaged position of the lever drive and releases in the disengaged position of the lever drive. Because the movement of the drive is transmitted via the eccentric to the actuated by him actuator, the drive pawl can only work on the ratchet when the pawl blocks the drive pawl in the engaged position of the lever drive. Only in this case attacks the lever drive and thus the drive pawl on a pin of the locking mechanism. In most cases, the pin is located on a catch of the locking mechanism and serves to its transfer from the prelocking in the main closed position.
Wenn jedoch die Rastklinke nicht für die Blockade der Antriebsklinke in der eingekuppelten Stellung des Hebeltriebes sorgt, kann die Antriebsklinke im Vergleich zu dem besagten Zapfen an dem Gesperre ausweichen und kommt das Gesperre von dem Hebeltrieb und folglich der gesamten Zuzieh-/Öffnungseinrichtung frei.However, if the pawl does not provide for the blockage of the drive pawl in the engaged position of the lever drive, the drive pawl may yield to the ratchet as compared to said peg and release the ratchet from the lever drive and thus the entire closing / opening device.
Dabei sorgt zusätzlich noch eine die Drehfalle und damit das Gesperre in öffnendem Sinne beaufschlagende Feder dafür, dass bei Einnahme der ausgekuppelten Stellung des Hebeltriebes die Antriebsklinke automatisch durch die Kraft der Drehfalle bzw. der ihr zugeordneten Feder selbstständig außer Eingriff gebracht wird. Die Antriebsklinke ist also selbstauswerfend ausgebildet.In this case, additionally provides the catch and thus the locking mechanism acting in the open sense spring that when taking the disengaged position of the lever drive the drive pawl is automatically disengaged automatically by the force of the catch or its associated spring. The drive pawl is therefore designed selbstauswerfend.
Hierzu ist die Antriebsklinke ferner und vorteilhaft mit einem sogenannten Vorschnitt ausgerüstet. Das heißt, der Hebeltrieb verfügt nach bevorzugter Ausführungsform im Bereich seiner Anlagefläche an dem Gesperre über einen Vorschnitt. Auf diese Weise ist das in Richtung "offen" federbelastete Gesperre in der Lage, unmittelbar den ausgekuppelten Hebeltrieb auszustellen. Das heißt, der an der Antriebsklinke des Hebeltriebes realisierte Vorschnitt unterstützt die Ausstellbewegung der Antriebsklinke, sobald diese nicht mehr mit Hilfe der Rastklinke in ihrer Position gehalten wird. Das ist unmittelbar nach Beaufschlagen der Rastklinke mit Hilfe des Auslösehebels bzw. Auswerferhebels der Fall. Durch diesen gleichsam Automatismus und das Ausnutzen der ohnehin vorhandenen Kraft der Feder des Gesperres für die Einnahme der ausgekuppelten Stellung des Hebeltriebs wird die Bedienkraft am Schlossbetätigungshebel deutlich reduziert.For this purpose, the drive pawl is further and advantageously equipped with a so-called pruning. That is, the lever drive has according to a preferred embodiment in the region of its contact surface on the locking mechanism via a precut. In this way, in the direction of "open" spring-loaded locking mechanism is able to issue immediately the disengaged lever drive. That is, the pre-cut realized on the drive pawl of the lever drive assists the deployment movement of the drive pawl as soon as it is no longer held in position by means of the latching pawl. This is the case immediately after applying the latch with the help of the release lever or ejector lever. Through this, as it were, automatism and the exploitation of the Any existing force of the spring of the locking mechanism for taking the disengaged position of the lever drive, the operating force on the lock operating lever is significantly reduced.
Es hat sich bewährt, wenn der Betätigungshebel bzw. das Betätigungselement zum Öffnen des Gesperres als einendseitig gelagerter Einarmhebel und gegebenenfalls abgekröpfter ausgebildet ist. Dadurch kann der am Antrieb vorgesehene Exzenter den besagten Betätigungshebel an seinem freien Ende unschwer beaufschlagen. Meistens ist der fragliche Betätigungshebel achsgleich zur Drehfalle des Gesperres gelagert, so dass ein besonders kompakter und kostengünstiger Aufbau erreicht wird. Gleichzeitig stellt diese Auslegung sicher, dass der Antrieb mit dem Exzenter unmittelbar oberhalb des Gesperres bzw. der Drehfalle angebracht werden kann und sich dadurch auch in sehr schmalen Kraftfahrzeugtürschlössern einsetzen lässt.It has proven useful if the actuating lever or the actuating element is designed to open the locking mechanism as a one-sided bearing Einarmhebel and optionally cranked. As a result, the eccentric provided on the drive can easily act on the said actuating lever at its free end. In most cases, the actuating lever in question is mounted coaxially to the catch of the locking mechanism, so that a particularly compact and cost-effective construction is achieved. At the same time, this design ensures that the drive can be mounted with the eccentric immediately above the locking mechanism or the catch and can thus be used in very narrow motor vehicle door locks.
In jedem Fall gelingt das Betätigen der Rastklinke und damit die Einnahme der ausgekuppelten Stellung des Hebeltriebes und folglich die Unterbrechung der mechanischen Wirkverbindung zwischen dem Antrieb und dem Gesperre mit besonders geringen Betätigungskräften. Es ist also bei einer gewollten (Not-)Unterbrechung beispielsweise der Zuziehbewegung mit einer unmittelbaren und bedienerkraftarmen Reaktion der Zuzieh-/Öffnungseinrichtung zu rechnen. Hierin sind die wesentlichen Vorteile zu sehen.In any case, the operation of the latch and thus the receipt of the disengaged position of the lever drive and consequently the interruption of the mechanical operative connection between the drive and the locking mechanism with particularly low actuation forces succeeds. So it is to be expected in a deliberate (emergency) interruption, for example, the closing movement with an immediate and low-operator reaction of the closing / opening device. Here are the main benefits.

In den Figuren ist ein Kraftfahrzeugtürverschluss dargestellt, der sich wie üblich aus einem hauptsächlich gezeigten Kraftfahrzeugtürschloss 1 und einem lediglich angedeuteten Schließbolzen 2 zusammensetzt. Regelmäßig ist der Schließbolzen 2 an einer zugehörigen Kraftfahrzeugkarosserie befestigt, während das Kraftfahrzeugtürschloss 1 eine Festlegung an einer nicht ausdrücklich dargestellten Kraftfahrzeugtür erfährt. Der Kraftfahrzeugtürverschluss bzw. das Kraftfahrzeugtürschloss 1 ist mit einem üblichen Gesperre 3, 4 aus Drehfalle 3 und Sperrklinke 4 ausgerüstet.In the figures, a motor vehicle door lock is shown, which is composed as usual of a mainly shown motor
Darüber hinaus verfügt der Kraftfahrzeugtürverschluss über eine Zuzieh-/Öffnungseinrichtung 5 bis 12, die vorliegend als Zuziehhilfe 5 bis 12 ausgestaltet ist. Die Zuzieh-/Öffnungseinrichtung 5 bis 12 ist mit wenigstens einem Antrieb 5, 6, 7, 8, 9 und einem Hebeltrieb 10, 11, 12 ausgerüstet.In addition, the motor vehicle door lock has a closing /
Der Antrieb 5, 6, 7, 8, 9 setzt sich aus einem Motor bzw. Elektromotor 5 und einer Antriebsschnecke 6 zusammen, die auf einer ausgangsseitig des Motors 5 vorgesehenen Antriebsachse angebracht ist und mit Hilfe des Motors 5 in Rotationen versetzt wird. Rotationen der Antriebsschnecke 6 führen dazu, dass ein hiermit kämmendes Schneckenrad 7 je nach Drehrichtung des reversierenden Motors bzw. Elektromotors 5 Drehungen im Uhrzeigersinn oder im Gegenuhrzeigersinn vollführt, wie dies ein Doppelpfeil in
Als Folge dieser Rotationen bewegt sich ein achsgleich zum Schneckenrad 7 auf diesem angebrachter Exzenter 8 mit endseitigem Zapfen 9 so, wie dies bei einer vergleichenden Betrachtung der
Bei diesem Vorgang schlägt der Zapfen 9 des Antriebes 5, 6, 7, 8, 9 an einem Betätigungshebel bzw. Betätigungselement 10 des Hebeltriebes 10, 11, 12 an. Der Betätigungshebel 10 ist vorliegend als Einarmhebel ausgebildet und mit seinem einen Ende achsgleich im Vergleich zur Drehfalle 3 gelagert. Das heißt, die Drehfalle 3 und der Betätigungshebel 10 verfügen über die gleiche Drehachse. Am freien Ende des abgekröpften Betätigungshebels 10 greift der Antrieb 5, 6, 7, 8, 9 mit dem Exzenter 8 bzw. dem Zapfen 9 an und beaufschlagt dieses freie Ende.In this process, the
Neben dem Betätigungshebel 10 weist der Hebeltrieb 10, 11, 12 als wesentliche Bestandteile zwei Klinken 11, 12 auf, nämlich eine Antriebsklinke 11 und eine Rastklinke 12. Sowohl die Antriebsklinke 11 als auch die Rastklinke 12 sind auf dem Betätigungshebel 10 gelagert, und zwar gemeinsam und zueinander achsversetzt.In addition to the
Von besonderer Bedeutung für die Funktionsweise ist noch ein Zapfen 13 am Gesperre 3, 4 bzw. genauer an der Drehfalle 3, welcher mit der Antriebsklinke 11 wechselwirkt, wie nachher noch näher erläutert wird. Schlussendlich findet sich ein Auslösehebel bzw. Auswerferhebel 14, welcher an seinem einen Ende mit der Rastklinke 12 wechselwirkt und mit seinem anderen Ende an einen Schlossbetätigungshebel 15 angeschlossen ist.Of particular importance for the operation is still a
Bei diesem Schlossbetätigungshebel 15 handelt es sich um einen Außenbetätigungshebel im Beispielfall, der mechanisch mit einem Türaußengriff verbunden ist. Alternativ oder zusätzlich kann der Auslösehebel bzw. Auswerferhebel 14 aber auch an einen Innenbetätigungshebel oder einen Betätigungshaupthebel des Kraftfahrzeugtürschlosses angeschlossen sein. Der Innenbetätigungshebel ist wie üblich mit einem Türinnengriff wirkverbunden. Der Betätigungshaupthebel mag sowohl vom Türinnengriff als auch vom Türaußengriff beaufschlagt werden und ist mit diesem mechanisch verbunden, was allerdings nicht dargestellt ist.In this
Die Funktionsweise ist wie folgt. Ausgehend von der Stellung "offen" des Gesperres 3, 4 bzw. der Drehfalle 3 in der
Dabei ist die Drehrichtung des Motors 5 so eingestellt, dass das von ihm beaufschlagte Schneckenrad 7 beim Übergang von der
Bei diesem Vorgang sorgt die Rastklinke 12 insgesamt dafür, dass der Hebeltrieb 10, 11, 12 in seinem eingekuppelten Zustand verbleibt. Denn in diesem Zustand bzw. der eingekuppelten Stellung sorgt der Hebeltrieb 10, 11, 12 für eine mechanische Wirkverbindung zwischen dem Antrieb 5, 6, 7, 8, 9 und dem Gesperre 3, 4. Das heißt, die Rastklinke 12 hält die Antriebsklinke 11 mit ihrer Anlagefläche 11 a in Anlage am Zapfen 13 der Drehfalle 3.In this process, the
Kommt es nun jedoch während dieses beschriebenen Zuziehvorganges zu einer Störung oder muss der Zuziehvorgang eine Notunterbrechung erfahren, so wird diese Notunterbrechung im Beispielfall dadurch eingeleitet, dass ein Bediener den Außenbetätigungshebel 15 ziehend in Pfeilrichtung gemäß
Dadurch liegen zugehörige Anlageflächen 12a einerseits an der Rastklinke 12 und 11 b andererseits an der Antriebsklinke 11 nicht mehr gegeneinander an und die Antriebsklinke 11 ist von der Rastklinke 12 frei. Als Folge hiervon liegt keine mechanische Wirkverbindung zwischen dem Antrieb 5, 6, 7, 8, 9 und dem Gesperre 3, 4 mehr vor, weil nun die Anschlagfläche 11a der Antriebsklinke 11 gegenüber dem Zapfen 13 an der Drehfalle 3 ausweicht und auch ausweichen kann.As a result, associated abutment surfaces 12a on the one hand on the
Dieser Vorgang wird noch dadurch unterstützt, dass die Antriebsklinke 11 an ihrer dem Gesperre 3, 4 respektive dem dortigen Zapfen 13 zugewandten Anschlagfläche 11a mit einem Vorschnitt ausgerüstet ist, wie die vergrößerte Darstellung in
Diese vom Zapfen 13 ausgeübte Kraft resultiert daher, dass die Drehfalle 3 mit Hilfe einer nicht ausdrücklich dargestellten Feder in Richtung "offen", das heißt im Uhrzeigersinn, vorgespannt ist. Das deutet ein Pfeil in dem vergrößerten Ausschnitt nach
Diese Kraft, die natürlich auch am Zapfen 13 ansteht, führt nun dazu, dass die Antriebsklinke 11 mit ihrem Vorschnitt an der dem Zapfen 13 zugewandten Anschlagfläche 11a unmittelbar von dem Zapfen 13 weggeschwenkt wird, sobald die Rastklinke 12 derartige Bewegungen nicht (mehr) blockiert. Das ist der Fall, sobald die Rastklinke 12 mit ihrer Anschlagfläche 12a die andere Anschlagfläche 11 b der Antriebsklinke 11 verlassen hat. Hierfür sorgt der Auslösehebel bzw. Auswerferhebel 14 und letztendlich eine Beaufschlagung des Außenbetätigungshebels 15 im Beispielfall.This force, which of course is also present on the
Es wird unmittelbar deutlich, dass die Notunterbrechung der Zuziehfunktion mit äußerst geringen Kräften gelingt. Denn erfindungsgemäß ist es lediglich erforderlich, die Rastklinke 12 geringfügig im Uhrzeigersinn mit Hilfe des Auslösehebels bzw. Auswerferhebels 14 zu verschwenken. Unmittelbar im Anschluss daran wird die Kraft der ohnehin der Drehfalle 3 zugeordneten Feder genutzt, um die Antriebsklinke 11 infolge des Vorschnittes von dem Zapfen 13 wegzuschwenken, so dass augenblicklich der Hebeltrieb 10, 11, 12 in seinen ausgekuppelten Zustand überführt wird und die mechanische Wirkverbindung vom Antrieb 5, 6, 7, 8, 9 zum Gesperre 3, 4 unterbrochen ist.It becomes immediately clear that the emergency interruption of the closing function succeeds with extremely small forces. Because according to the invention, it is only necessary to pivot the
Als Folge hiervon wird das Gesperre 3, 4 unmittelbar freigegeben, was dann selbstverständlich auch für den Schließbolzen 2 gilt, wenn sich das Kraftfahrzeugtürschloss 1 im Zustand "entriegelt" befindet. Anderenfalls, das heißt in Stellung "verriegelt" geht das Gesperre 3, 4 in die Vorschließstellung bzw. Vorraststellung zurück. Jedenfalls ist die Zuziehfunktion unterbrochen. Meistens wird das Kraftfahrzeugtürschloss 1 jedoch gleichzeitig entriegelt. Die zum Kraftfahrzeugtürschloss 1 zugehörige Kraftfahrzeugtür lässt sich dementsprechend unmittelbar öffnen bzw. der Antrieb 5, 6, 7, 8, 9 geht mit Bezug auf die Zuziehfunktion leer.As a result, the
Für den Fall, dass keine Unterbrechung der Zuziehfunktion vorliegt, befindet sich der Kraftfahrzeugtürverschluss nach dem Zuziehen in der Stellung gemäß
Bei der beschriebenen Notunterbrechung geht das Gesperre 3, 4 entweder in die Vorraststellung nach
Im Rahmen der alternativen Ausführungsform entsprechend der
Der Steuerhebel 16 dient dazu, die Antriebsklinke 11 mit der Drehfalle 3 in Eingriff zu bringen. Der Steuerhebel 16 betätigt die Antriebsklinke 11 sobald die Drehfalle 3 die Vorraststellung erreicht hat und der Antrieb 5,6,7,8,9 eingeschaltet wurde. Angesteuert wird der Steuerhebel 16 von dem Exzenter 8,9. Erst wenn die Antriebsklinke 11 mit der Drehfalle 3 gekuppelt ist, beginnt der Zuziehvorgang. Ein Vorteil des Steuerhebels 16 ist das Vermeiden einer ungewollten Kollision von Antriebsklinke 11 und Übertragungshebel 10 mit der Drehfalle 3, wenn die Antriebsklinke 11 bzw., wie in der erfingsgemäßen Lösung, nicht direkt vom Exzenter 8,9 angesteuert wird. Die Ansteuerung des Steuerhebels 16 kann, wie in
