Description

Die Erfindung betrifft ein Kraftfahrzeugschloss, insbesondere Kraftfahrzeugtürschloss, mit einem Gesperre aus im Wesentlichen Drehfalle und Sperrklinke als Gesperrebauteile, ferner mit einem motorisch angetriebenen Stellelement für das Gesperre, und mit einem Bewegungen des Gesperres und/oder des Stellelementes abtastenden Sensor.The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and pawl as locking components, furthermore with a motor-driven actuating element for the locking mechanism, and with a sensor that scans movements of the locking mechanism and / or the actuating element.

Bei dem Kraftfahrzeugschloss handelt es sich typischerweise um ein Kraftfahrzeugtürschloss und hier im Allgemeinen um ein Heckklappenschloss. Grundsätzlich kann das Kraftfahrzeugschloss aber auch als Fronthaubenschloss, Schloss für eine Sitzverriegelung, Tankklappenschloss, Ladeklappenschloss etc. ausgebildet sein. Sofern im Allgemeinen Heckklappenschlösser betrachtet werden, sind diese meistens mit einem motorischen Antrieb ausgerüstet. Der Antrieb arbeitet auf das Stellelement.The motor vehicle lock is typically a motor vehicle door lock and here generally a tailgate lock. In principle, however, the motor vehicle lock can also be designed as a front hood lock, a lock for a seat lock, a tank flap lock, a loading flap lock, etc. If tailgate locks are generally considered, they are usually equipped with a motor drive. The drive works on the control element.

Mithilfe des Stellelementes kann dann seinerseits das Gesperre von einer Vorraststellung in einer Hauptraststellung überführt werden. In diesem Fall arbeitet der Antrieb bzw. elektromotorische Antrieb als Zuziehungsantrieb oder fungiert als Zuziehhilfe. Grundsätzlich kann der Antrieb aber auch als Öffnungsantrieb realisiert sein, der die Sperrklinke zur Öffnung des Gesperres von der Drehfalle abhebt. Eine solche Ausführungsform wird nachfolgend primär betrachtet.With the aid of the adjusting element, the locking mechanism can then be transferred from a pre-locking position to a main locking position. In this case, the drive or the electric motor drive works as a closing drive or acts as a closing aid. In principle, however, the drive can also be implemented as an opening drive, which lifts the pawl off the catch to open the locking mechanism. Such an embodiment is primarily considered below.

Im gattungsbildenden Stand der Technik nach der DE 10 2018 101 142 A1 sind ein Auslöseelement und zusätzlich ein Speicherelement realisiert. Das Speicherelement hält das Auslöseelement und damit die Sperrklinke zumindest während einer Öffnungsbewegung der Drehfalle in einer bezüglich des Gesperres unwirksamen Stellung. Der zusätzlich vorgesehene Sensor dient zumindest zur Abfrage der Stellung der Sperrklinke.In the generic prior art according to the DE 10 2018 101 142 A1 a trigger element and an additional storage element are implemented. The storage element holds the release element and thus the pawl, at least during an opening movement of the rotary latch, in an ineffective position with respect to the locking mechanism. The additionally provided sensor serves at least to query the position of the pawl.

Meistens muss nicht nur die Offenstellung der Drehfalle mithilfe des Sensors überwacht und abgefragt werden. Sondern es ist zusätzlich und typischerweise ebenso erforderlich, zumindest noch die Hauptraststellung des Gesperres und möglicherweise auch die Vorraststellung des Gesperres abzufragen. Dazu sind in der Praxis weitere und eigene Sensoren vorgesehen und realisiert. Das führt zu einem erhöhten Herstellungs- und Montageaufwand.In most cases, not only the open position of the rotary latch has to be monitored and queried with the aid of the sensor. Instead, it is additionally and typically also necessary to query at least the main locking position of the locking mechanism and possibly also the preliminary locking position of the locking mechanism. For this purpose, additional and separate sensors are provided and implemented in practice. This leads to increased manufacturing and assembly costs.

Bei einem vergleichbaren Kraftfahrzeugtürschloss entsprechend der DE 10 2004 030 902 A1 ist ein mit der Drehfalle bzw. der Sperrklinke wechselwirkendes Zwischenelement realisiert, welches Bewegungen des Gesperres auf einen Sensor überträgt. Dazu verfügt das Zwischenelement über wenigstens ein von der Drehfalle gesteuertes und ihre Bewegungen speicherndes Drehfallenfederelement.With a comparable motor vehicle door lock according to DE 10 2004 030 902 A1 an intermediate element interacting with the rotary latch or the pawl is implemented, which transmits movements of the locking mechanism to a sensor. For this purpose, the intermediate element has at least one rotary latch spring element which is controlled by the rotary latch and stores its movements.

Mithilfe des Zwischenelementes und des Sensors wird die Hauptrastposition des Gesperres abgefragt. Hierzu korrespondiert die komplett in die Drehfalle eingefallene Sperrklinke. Bei dem Sensor handelt es sich um einen Mikroschalter, der ständig von dem Drehfallenfederelement beaufschlagt wird. Sein Signal schließt dadurch einen von einer Steueranlage abgefragten Schaltkreis.The main locking position of the locking mechanism is queried with the aid of the intermediate element and the sensor. The pawl, which has completely fallen into the rotary latch, corresponds to this. The sensor is a microswitch that is constantly acted upon by the rotary latch spring element. Its signal thereby closes a circuit queried by a control system.

Der Stand der Technik hat sich grundsätzlich bewährt, lässt allerdings nach wie vor und unverändert Verbesserungen insbesondere dahingehend zu, dass der montage- und konstruktionstechnische Aufwand verringert wird. Das gilt insbesondere im Hinblick auf die Anzahl der erforderlichen Sensoren, um die verschiedenen Positionen des Gesperres sicher abfragen zu können. Hierbei handelt es sich typischerweise um die Offenposition, Vorrastposition und Hauptrastposition des Gesperres. Denn im Stand der Technik sind an dieser Stelle zur Abfrage der verschiedenen Positionen jeweils eigene Sensoren erforderlich. Das treibt nicht nur den herstellungs- und montagetechnischen Aufwand hoch, sondern auch und insbesondere die Kosten, weil solche Sensoren relativ teuer in der Beschaffung ausgebildet sind. Hier will die Erfindung insgesamt Abhilfe schaffen.The state of the art has basically proven itself, but still and unchanged allows improvements, in particular to the effect that the assembly and construction effort is reduced. This is especially true with regard to the number of sensors required to safely query the various positions of the locking mechanism. These are typically the open position, pre-locking position and main locking position of the locking mechanism. Because in the prior art, separate sensors are required at this point to query the various positions. This not only drives up the manufacturing and assembly outlay, but also, and in particular, the costs, because such sensors are relatively expensive to procure. The invention aims to provide a remedy here overall.

Der Erfindung liegt das technische Problem zugrunde, ein derartiges Kraftfahrzeugschloss und insbesondere Kraftfahrzeugtürschloss so weiterzuentwickeln, dass der montage- und herstellungstechnische Aufwand reduziert werden und als Folge hiervon auch die Herstellungskosten sinken.The invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock so that that the assembly and manufacturing effort are reduced and, as a result, the manufacturing costs are also reduced.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßes Kraftfahrzeugschloss und insbesondere Kraftfahrzeugtürschloss im Rahmen der Erfindung dadurch gekennzeichnet, dass der einzige Sensor zur Abtastung sowohl axialer als auch radialer Bewegungen des Stellelementes und/oder des Gesperrebauteils eingerichtet ist.To solve this technical problem, a generic motor vehicle lock and in particular motor vehicle door lock is characterized within the scope of the invention in that the single sensor is set up to sense both axial and radial movements of the actuating element and / or the locking component.

Im Rahmen der Erfindung wird also zunächst einmal mit einem (einzigen) Sensor gearbeitet. Dieser einzige Sensor ist nun zur Abtastung eingerichtet. Dabei werden sowohl Axialbewegungen als auch radiale Bewegungen alternativ oder kumulativ mithilfe des Sensors erfasst. Meistens werden sowohl axiale als auch radiale Bewegungen des Stellelementes bzw. des Gesperrebauteils erfasst, und zwar mit dem einzigen Sensor.In the context of the invention, one (single) sensor is therefore initially used. This single sensor is now set up for scanning. Both axial movements and radial movements are recorded alternatively or cumulatively with the aid of the sensor. In most cases, both axial and radial movements of the adjusting element or the locking component are recorded, specifically with the single sensor.

Die fraglichen axialen bzw. radialen Bewegungen werden dabei von dem Stellelement und/oder dem Gesperrebauteil vollführt und mithilfe des Sensors abgetastet. Über eine Position des Stellelements kann mittelbar auf die Position des Gesperres rückgeschlossen werden. Beispielsweise korrespondiert eine erreichte Abhebeposition des motorisch angetriebenen Stellelementes im Zusammenhang mit einem Öffnungsvorgang dazu, dass die Drehfalle sicher ihre Öffnungsposition erreichen kann. Unter einer Abhebeposition ist in diesem Zusammenhang eine Position zu verstehen, in der die Sperrklinke von der Drehfalle abgehoben ist und sich somit die Drehfalle in ihre Offenstellung drehen kann. Ebenso kann durch Erfassung, ob das Gesperre sicher die Hauptraststellung erreicht hat, eine sichere Schließung des Gesperres erkannt werden.The axial or radial movements in question are carried out by the adjusting element and / or the locking component and scanned with the aid of the sensor. The position of the locking mechanism can be inferred indirectly via a position of the adjusting element. For example, a lift-off position reached by the motor-driven adjusting element in connection with an opening process corresponds to the fact that the rotary latch can safely reach its opening position. In this context, a lift-off position is to be understood as a position in which the pawl is lifted from the rotary latch and the rotary latch can thus rotate into its open position. Likewise, by detecting whether the locking mechanism has safely reached the main notch position, safe locking of the locking mechanism can be recognized.

Es ist aber auch möglich, dass eine Axialbewegung des Stellelementes mit beispielsweise der Einnahme der Vorrastposition des Gesperres einhergeht und die zusätzliche radialer Bewegung des Stellelementes die daran anschließende Einnahme der Hauptrastposition wiedergibt. In einem solchen Fall kann der einzige Sensor durch die Abtastung sowohl der axialen als auch radialen Bewegung des motorisch angetriebenen Stellelementes im Beispielfall die Vorrastposition und die Hauptrastposition sicher erfassen und an die den Sensor abfragende Steuereinheit übermitteln.However, it is also possible that an axial movement of the adjusting element is associated with, for example, the assumption of the pre-locking position of the locking mechanism and the additional radial movement of the adjusting element reproduces the subsequent assumption of the main locking position. In such a case, the single sensor can by scanning both the axial and radial movement of the motor-driven adjusting element in the example Detect the pre-locking position and the main locking position reliably and transmit them to the control unit querying the sensor.

Im Regelfall wird der einzige Sensor jedoch zur Abtastung eines Gesperrebauteils und hier meistens der Sperrklinke eingesetzt und ist entsprechend eingerichtet. Dazu wechselwirkt der Sensor meistens mit einer Kontur. Die Kontur ist zu diesem Zweck im Regelfall an einem drehachsfernen Ende des Stellelementes bzw. Gesperrebauteils angeordnet.As a rule, however, the only sensor is used to scan a locking component, and here mostly the pawl, and is set up accordingly. To do this, the sensor usually interacts with a contour. For this purpose, the contour is generally arranged at an end of the adjusting element or locking component remote from the axis of rotation.

Nach bevorzugter Ausführungsform findet sich die Kontur am drehachsenfernen Ende des Gesperrebauteils und insbesondere der Sperrklinke. Hierbei geht die Erfindung von der Erkenntnis aus, dass mithilfe des motorisch angetriebenen Stellelementes die Sperrklinke abgehoben wird, um der Drehfalle die Öffnung zu ermöglichen.According to a preferred embodiment, the contour is found at the end of the locking component remote from the axis of rotation and in particular the pawl. The invention is based on the knowledge that the locking pawl is lifted off with the aid of the motor-driven adjusting element in order to enable the rotary latch to open.

Um nun die sichere Einnahme der Hauptrastposition des Gesperres zu erfassen, vollführt die Sperrklinke im Beispielsfall eine sowohl axiale als auch radiale Bewegung. Diese beiden Bewegungen können nacheinander oder gleichzeitig seitens der Sperrklinke vollführt werden. Grundsätzlich kann natürlich auch das Stellelement als solches alternativ zur Sperrklinke solche axialen und radialen Bewegungen vollziehen, die dann wiederum mithilfe des einzigen Sensors erfasst werden.In order to detect the safe assumption of the main locking position of the locking mechanism, the pawl performs both an axial and a radial movement in the example. These two movements can be carried out one after the other or at the same time on the part of the pawl. In principle, of course, the actuating element as such can also execute such axial and radial movements as an alternative to the locking pawl, which in turn are then detected with the aid of the single sensor.

Jedenfalls ist der Sensor in der Lage, sowohl axiale als auch radiale Bewegungen des Stellelementes respektive Gesperrebauteils zu erfassen. Da die fraglichen Bewegungen zeitlich nacheinander ebenso wie zeitlich teilweise oder vollständig überlappend seitens des Stellelementes bzw. Gesperrebauteils vollzogen werden können, lässt sich aus den zugehörigen Sensorsignalen der Bewegungsablauf des Stellelementes bzw. Gesperrebauteils eindeutig nachvollziehen. Als Folge hiervon kann zweifelsfrei auch die Einnahme der Abhebeposition der Sperrklinke mithilfe des einzigen Sensors erfasst werden. Ebenso lässt sich beispielsweise der Übergang von der Vorrastposition in die Hauptrastposition sensorisch nachprüfen, und zwar erfindungsgemäß unter Rückgriff auf einen einzigen Sensor und ausdrücklich unter Verzicht auf mehrere Sensoren. Dadurch lässt sich der montage- und herstellungstechnische Aufwand deutlich gegenüber bisherigen Ausführungsformen reduzieren.In any case, the sensor is able to detect both axial and radial movements of the adjusting element or locking component. Since the movements in question can be performed one after the other as well as partially or completely overlapping in time on the part of the adjusting element or locking component, the movement sequence of the adjusting element or locking component can be clearly understood from the associated sensor signals. As a result of this, the assumption of the lifting position of the pawl can also be detected with the aid of the single sensor without any doubt. Likewise, for example, the transition from the pre-locking position to the main locking position can be checked by sensors, namely according to the invention with recourse to a single sensor and expressly dispensing with several Sensors. As a result, the assembly and manufacturing effort can be significantly reduced compared to previous embodiments.

Wie bereits erläutert, kann beispielsweise aus der Abfolge der sensorisch erfassten Axialbewegung sowie der ebenfalls sensorisch erfassten Radialbewegung des Stellelementes bzw. Gesperrebauteils auf seinen Bewegungsablauf rückgeschlossen werden, und zwar eindeutig. Dadurch lässt sich auch die sichere Einnahme der Hauptrastposition des Gesperres mit einer bisher nicht für möglich gehaltenen Präzision erfindungsgemäß erfassen. Das ist besonders wichtig vor dem Hintergrund, dass an das Erreichen der Hauptrastposition seitens des Gesperres die zuvor angesprochenen weiteren Funktionen (Diebstahlsicherung, Aktivierung von Sicherheitssystemen für die Insassen etc.) gekoppelt sind. Dies ist insbesondere vor dem Hintergrund wichtig, dass die Sperrklinke bei der bevorzugten Ausführungsform nicht nur einfach wegschwenkt, sondern mit Hilfe des Stellelements translatorische Bewegungen innerhalb eines Bereichs, der durch zwei zueinander senkrechte Achsen vorgegeben ist, bewegen kann.As already explained, conclusions can be drawn about its movement sequence, for example, from the sequence of the sensor-recorded axial movement and the likewise sensor-recorded radial movement of the actuating element or locking component, specifically. As a result, according to the invention, the safe assumption of the main locking position of the locking mechanism can also be detected with a precision previously not considered possible. This is particularly important in view of the fact that the previously mentioned additional functions (anti-theft protection, activation of safety systems for the occupants, etc.) are linked to the locking mechanism's reaching the main locking position. This is particularly important in view of the fact that the pawl in the preferred embodiment not only simply swivels away, but can also move translational movements with the aid of the adjusting element within a range that is predetermined by two mutually perpendicular axes.

Nach vorteilhafter Ausgestaltung ist der Sensor ortsfest sowie gegenüberliegend zur Kontur an einem Gehäuse angeordnet. Bei dem Gehäuse kann es sich um ein Schlossgehäuse bzw. eine Kunststoffhaube und/oder einen das Gesperre lagernden metallischen Schlosskasten handeln. Die Kontur ist ihrerseits im Allgemeinen mit einer Axialbewegungen folgenden Erhebung und zusätzlich einer Drehbewegungen folgenden ebenen Fläche ausgerüstet. D. h., mithilfe der Erhebung gegenüber der ebenen Fläche kann unschwer eine Axialbewegung der Kontur und mithin des mithilfe des Sensors überwachten Stellelementes bzw. Gesperrebauteils erfasst werden. Über die ebene Fläche lassen sich darüber hinaus Drehbewegungen des Stellelementes bzw. Gesperrebauteils mithilfe des Sensors detektieren. Denn die drehachsferne Anbringung der Kontur im Vergleich zum Stellelement bzw. Gesperrebauteil sorgt dafür, dass die ebene Fläche als Bestandteil der Kontur entsprechende Schwenkbewegungen an eben diesem drehachsfernen Ende vollführt, die dann mithilfe des einzigen Sensors erfasst werden.According to an advantageous embodiment, the sensor is stationary and is arranged opposite the contour on a housing. The housing can be a lock housing or a plastic cover and / or a metallic lock case supporting the locking mechanism. For its part, the contour is generally equipped with an elevation following axial movements and, in addition, a flat surface following rotational movements. That is, with the help of the elevation opposite the flat surface, an axial movement of the contour and thus of the adjusting element or locking component monitored with the aid of the sensor can easily be detected. In addition, rotary movements of the actuating element or locking component can be detected with the aid of the sensor via the flat surface. This is because the attachment of the contour away from the axis of rotation compared to the control element or locking component ensures that the flat surface as part of the contour executes corresponding pivoting movements at this end that is remote from the axis of rotation, which are then detected with the aid of the single sensor.

Bei dem Sensor handelt sich im einfachsten Fall um einen Schalter und insbesondere Mikroschalter. Neben einer solchen besonders kostengünstigen und einfach zu montierenden Lösung können natürlich auch andere Sensoren wie beispielsweise Abstandssensoren auf optischer Basis, mit Ultraschall arbeitende Sensoren, Hallsensoren etc. zur Anwendung kommen bzw. alternativ eingesetzt werden.In the simplest case, the sensor is a switch and, in particular, a microswitch. In addition to such a particularly cost-effective and easy-to-assemble solution, other sensors such as, for example, distance sensors on an optical basis, sensors operating with ultrasound, Hall sensors, etc., can of course also be used or alternatively used.

Wie bereits erläutert, ist die Kontur vorteilhaft an der Sperrklinke vorgesehen. In diesem Zusammenhang hat es sich darüber hinaus als günstig erwiesen, wenn die Sperrklinke drehbar am Stellelement gelagert ist. Das Stellelement ist seinerseits um eine Achse drehbar gegenüber dem Kunststoffgehäuse respektive Schlosskasten gelagert. Entsprechende Drehbewegungen des Stellelementes werden dabei mithilfe des elektromotorischen Antriebes initiiert.As already explained, the contour is advantageously provided on the pawl. In this context, it has also proven to be advantageous if the pawl is rotatably mounted on the adjusting element. The adjusting element is in turn mounted rotatably about an axis relative to the plastic housing or lock case. Corresponding rotary movements of the adjusting element are initiated with the aid of the electric motor drive.

Grundsätzlich lassen sich aber auch sowohl die Vorrastposition des Gesperres als auch seine Hauptrastposition durch die Kombination der Kontur am Stellelement bzw. Gesperrebauteil und dessen zugleich axiale wie auch radiale Bewegung getrennt voneinander ermitteln. Daneben ist auch eine Unterscheidung zwischen einer Offenposition und Hauptrastposition des Gesperres auf diese Weise möglich. Selbst die Erfassung der Offenposition, Vorrastposition und Hauptrastposition lässt sich mit der erfindungsgemäßen Anordnung realisieren und umsetzen.In principle, however, both the pre-latching position of the locking mechanism and its main locking position can also be determined separately from one another by combining the contour on the actuating element or locking component and its simultaneous axial and radial movement. In addition, a distinction between an open position and the main locking position of the locking mechanism is possible in this way. Even the detection of the open position, pre-locking position and main locking position can be realized and implemented with the arrangement according to the invention.

Beispielsweise mag die Kontur nicht nur mit einer Erhebung sondern zwei Erhebungen beidseitig der dazwischen angeordneten ebenen Fläche ausgerüstet sein. In diesem Fall ist es denkbar, dass die eine erste und vordere Erhebung zu einer definierten Position, die ebene Fläche zu einer weiteren zweiten Position und die hintere zweite Erhebung zu einer schließlich noch zu ermittelnden zusätzlichen dritten Position korrespondiert, die sämtlich mithilfe des Sensors bzw. Schalters erfasst und von der Steuereinheit voneinander unterschieden werden können. Das alles gelingt unter Berücksichtigung eines konstruktiv und herstellungstechnisch einfachen Aufbaus, sodass mit im Vergleich zum Stand der Technik deutlich verringerten Kosten zu rechnen ist. Hierin sind die wesentlichen Vorteile zu sehen.For example, the contour may be equipped not only with one elevation but two elevations on both sides of the flat surface arranged in between. In this case, it is conceivable that one of the first and front elevations corresponds to a defined position, the flat surface corresponds to a further second position and the rear second elevation corresponds to an additional third position to be finally determined, all of which correspond with the aid of the sensor or Detected switch and can be distinguished from one another by the control unit. All of this succeeds taking into account a structurally and technically simple structure, so that significantly reduced costs can be expected compared to the prior art. This is where the main advantages can be seen.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

In den Figuren ist ein Kraftfahrzeugschloss dargestellt, bei dem es sich im Ausführungsbeispiel um ein Kraftfahrzeugtürschloss handelt, welches konkret als Heckklappenschloss ausgebildet ist. Das fragliche und in der Übersicht in der Fig. 1 dargestellte Kraftfahrzeugschloss verfügt in seinem grundsätzlichen Aufbau über ein Gesperre 1, 2 aus im Wesentlichen Drehfalle 1 und Sperrklinke 2 als beide Gesperrebauteile 1, 2. Ferner ist ein motorisch angetriebenes Stellelement 3 für das Gesperre 1, 2 realisiert. Das Stellelement 3 ist im Ausführungsbeispiel als dreieckförmiger Hebel ausgebildet und um eine Drehachse 4 drehbar in einem Schlosskasten 5 gelagert.The figures show a motor vehicle lock which, in the exemplary embodiment, is a motor vehicle door lock which is specifically designed as a tailgate lock. The question in question and in the overview in the Fig. 1 The motor vehicle lock shown has in its basic structure a locking mechanism 1, 2 consisting essentially of rotary latch 1 and pawl 2 as both locking components 1, 2. Furthermore, a motor-driven actuating element 3 for the locking mechanism 1, 2 is implemented. In the exemplary embodiment, the actuating element 3 is designed as a triangular lever and is mounted in a lock case 5 so as to be rotatable about an axis of rotation 4.

Der metallische Schlosskasten 5 dient auch zur Lagerung der Drehfalle 1. Dazu verfügt die Drehfalle 1 über eine Drehachse 6. Die Sperrklinke 2 ist dagegen nach dem Ausführungsbeispiel mit ihrer Drehachse 7 an dem Stellelement 3 gelagert.The metallic lock case 5 also serves to support the rotary latch 1. For this purpose, the rotary latch 1 has an axis of rotation 6. The pawl 2, on the other hand, is supported by its axis of rotation 7 on the actuating element 3 according to the exemplary embodiment.

Zum grundsätzlichen Aufbau gehört noch ein Antrieb 9, 10 für das auf diese Weise motorisch angetriebene Stellelement 3. Im Ausführungsbeispiel sorgt der Antrieb 9, 10 dafür, dass das Stellelement 3 ausgelöst wird und folglich das Gesperre 1, 2 eine Öffnung erfährt.The basic structure also includes a drive 9, 10 for the actuating element 3, which is motor-driven in this way. In the exemplary embodiment, the drive 9, 10 ensures that the actuating element 3 is triggered and consequently the locking mechanism 1, 2 experiences an opening.

Zu diesem Zweck setzt sich der Antrieb 9, 10 im Beispielfall aus einem Antriebshebel 9 und einer zum Auslösen des Stellelementes 3 in Pfeilrichtung bewegbaren Antriebsstange 10 zusammen, welche insgesamt dafür sorgt, dass das Stellelement 3 zum Auslösen und damit Öffnen des Gesperres 1, 2 im Gegenuhrzeigersinn um seine Achse 4 verschwenkt wird.For this purpose, the drive 9, 10 is composed in the example of a drive lever 9 and a drive rod 10 that can be moved in the direction of the arrow to trigger the actuating element 3, which overall ensures that the actuating element 3 for triggering and thus opening the locking mechanism 1, 2 in Is pivoted counterclockwise about its axis 4.

Zum weiteren grundsätzlichen Aufbau gehört schließlich noch ein Sensor 13, welcher mit einer nachfolgend noch näher zu beschreibenden Kontur 14, 15 wechselwirkt und dadurch Bewegungen des Gesperres 1, 2 abtasten kann. Dazu ist der Sensor 13 im Ausführungsbeispiel an eine seine Signale auswertende Steuereinheit 16 angeschlossen.Finally, a further basic structure also includes a sensor 13 which interacts with a contour 14, 15 to be described in more detail below and can thus sense movements of the locking mechanism 1, 2. For this purpose, the sensor 13 in the exemplary embodiment is connected to a control unit 16 that evaluates its signals.

Erfindungsgemäß handelt es sich bei dem fraglichen Sensor 13 um den einzigen Sensor des dargestellten Kraftfahrzeugtürschlosses, mit dessen Hilfe sämtliche relevanten Positionen des Gesperres 1, 2 erfasst und abgefragt werden können. Dazu ist der einzige Sensor 13 im Rahmen der Erfindung zur Abtastung sowohl axialer als auch radialer Bewegungen des Gesperrebauteils 2, konkret der Sperrklinke 2, eingerichtet. Über die sowohl axialen als auch radialen Bewegungen der Sperrklinke 2 im Beispielfall kann auf die einwandfreie Einnahme einer Abhebeposition der Sperrklinke, oder auch eine in der Fig. 1 dargestellten Hauptrastposition seitens der die Signale des Sensors 13 auswertenden Steuereinheit 16 rückgeschlossen werden. Es ist grundsätzlich aber auch möglich, dass mithilfe des Sensors 13 in Wechselwirkung mit der Kontur 14, 15 an der Sperrklinke 2 nicht nur die bereits angesprochene Hauptrastposition, sondern zusätzlich beispielsweise auch eine Vorrastposition oder auch Offenposition des Gesperres 1, 2 ermittelt wird. Das wurde in der Beschreibungseinleitung bereits erläutert.According to the invention, the sensor 13 in question is the only sensor of the illustrated motor vehicle door lock, with the aid of which all relevant positions of the locking mechanism 1, 2 can be recorded and queried. For this purpose, the single sensor 13 is set up within the scope of the invention for scanning both axial and radial movements of the locking component 2, specifically the pawl 2. About the both axial and radial movements of the pawl 2 in the example case, the correct assumption of a lifting position of the pawl, or one in the Fig. 1 The main notch position shown can be inferred by the control unit 16 evaluating the signals from the sensor 13. In principle, however, it is also possible that, with the aid of the sensor 13 in interaction with the contour 14, 15 on the pawl 2, not only the already mentioned main detent position, but also, for example, a pre-detent position or also an open position of the locking mechanism 1, 2 is determined. This has already been explained in the introduction to the description.

Bei einem Vergleich der Figuren 1 und 2 und insbesondere bei Betrachtung der Detaildarstellung in der Fig. 2 wird deutlich, dass die Kontur 14, 15 eine Erhebung 14 und zusätzlich eine ebene Fläche 15 aufweist. Mithilfe der Erhebung 14 können in der Fig. 2 durch einen Doppelpfeil angedeutete Axialbewegungen A der vergrößert dargestellten Sperrklinke 2 mithilfe des Sensors 13 erfasst werden. Die ebene Fläche 15 dient demgegenüber dazu, Radialbewegungen R der Sperrklinke 2 erfassen bzw. abfragen zu können. Das ist unschwer möglich, weil sich die Kontur 14, 15 am drehachsfernen Ende der Sperrklinke 2 befindet, wie man bei einem Vergleich der Figuren 1 und 2 unmittelbar nachvollziehen kann.When comparing the Figures 1 and 2 and especially when looking at the detailed representation in the Fig. 2 it becomes clear that the contour 14, 15 has an elevation 14 and, in addition, a flat surface 15. Using the survey 14 can in the Fig. 2 Axial movements A, indicated by a double arrow, of the pawl 2, shown enlarged, can be detected with the aid of the sensor 13. In contrast, the flat surface 15 serves to be able to detect or query radial movements R of the pawl 2. This is not difficult because the contour 14, 15 is located at the end of the pawl 2 remote from the axis of rotation, as can be seen when comparing the Figures 1 and 2 can understand immediately.

Der Sensor 13 ist insgesamt als Schalter und insbesondere Mikroschalter ausgeführt. Als Folge hiervon wird ein den Schalter betätigender und in der Fig. 2 besonders zu erkennender Zapfen 13' sowohl bei einer Axialbewegung A der Erhebung 14 als auch der Radialbewegung R der ebenen Fläche 15 beaufschlagt und erzeugt ein entsprechendes Signal des Sensors 13, welches mithilfe der Steuereinheit 16 ausgewertet werden kann.The sensor 13 is designed overall as a switch and, in particular, a microswitch. As a result, a switch actuating and in the Fig. 2 Particularly recognizable pin 13 'is acted upon both during an axial movement A of the elevation 14 and the radial movement R of the flat surface 15 and generates a corresponding signal from the sensor 13, which can be evaluated with the aid of the control unit 16.

Ausgehend von der in der Fig. 1 dargestellten Hauptrastposition des Gesperres 1, 2 kann das Gesperre 1, 2 ausgelöst bzw. geöffnet werden, indem die Antriebsstange bzw. Stellstange 10 des Antriebes 9, 10 in der in Fig. 1 angedeuteten Pfeilrichtung abwärts bewegt wird. Dadurch wird das Stellelement 3 im Gegenuhrzeigersinn um seine Achse 4 gegen die Kraft der Feder 11 rotiert. Als Folge hiervon wandert auch die Sperrklinke 2 mit ihrer Drehachse 7 und geht in die Abhebeposition über, sodass hierdurch die Drehfalle 1 insgesamt freigegeben wird und im Gegenuhrzeigersinn um ihre Achse 6 aufschwenkt.Based on the in the Fig. 1 The main locking position of the locking mechanism 1, 2 shown here, the locking mechanism 1, 2 can be triggered or opened by moving the drive rod or actuating rod 10 of the drive 9, 10 in the position shown in FIG Fig. 1 indicated arrow direction is moved downwards. As a result, the adjusting element 3 is rotated counterclockwise about its axis 4 against the force of the spring 11. As a result of this, the pawl 2 also migrates with its axis of rotation 7 and goes into the lift-off position, so that the rotary latch 1 is released as a whole and pivots counterclockwise about its axis 6.

Umgekehrt korrespondiert eine Schließbewegung des Gesperres 1, 2 zunächst dazu, dass die Drehfalle 1 mithilfe des einfahrenden und nicht ausdrücklich dargestellten Schließbolzens im Uhrzeigersinn um ihre Achse 6 verschwenkt. Dadurch fällt die Sperrklinke 2 zunächst in die Vorrast und dann in die in der Fig. 1 dargestellte Hauptrast ein, sodass die Hauptrastposition erreicht wird.Conversely, a closing movement of the locking mechanism 1, 2 initially corresponds to the rotary latch 1 pivoting clockwise about its axis 6 with the aid of the retracting locking bolt, which is not expressly shown. As a result, the pawl 2 first falls into the preliminary detent and then into the Fig. 1 shown main notch so that the main notch position is reached.
