Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, also with a working on the ratchet operating lever mechanism with release lever, and with a locking lever which blocks the ratchet at least when occurring acceleration forces of predetermined size, for example in an accident ("crash").
- An operating lever mechanism is usually composed of one or more levers. Usually, an Innbet Ober Trentshebel, an external operating lever and a release lever are used in the minimum. In addition, the operating lever mechanism often also includes a clutch lever. If the actuating lever mechanism is acted upon, the locking mechanism can be opened in this way. For this purpose, typically the release lever engages a pawl of the ratchet and lifts it from an associated catch. The catch then opens spring-assisted and releases a previously captured locking pin. As a result, an associated motor vehicle door can be opened.
- An acting on an operating lever mechanism locking lever is, for example, in the DE 197 19 999 A1 presented.
- the lock or the blocking lever blocks an opening lever when the accelerating forces described in the course of an accident.
- the lock or the locking lever and the opening lever are arranged transversely to the pivoting direction of the opening lever relative to each other displaceable. When caused by the increased acceleration forces relative displacement of the opening lever runs into the lock. This is to unintentional opening in the event of a crash in structurally simplified design are made available, Also, a permanent blocking of the opening lever is basically addressed.
- a crash lock on a door lock is described.
- This has a pivoting locking lever, which can pivot by mass force about its pivot axis in a blocking element locking a transmission element.
- a counter-locking surface is provided, which is designed stationary.
- a motor vehicle door lock according to the preamble of claim 1 is known, which is provided with a lockable by a pawl in a closed position and after a by actuation of a pawl actuator (28) pivoting of the pawl from this blocking position in a release position movable catch.
- this document proposes that the pawl is movement blocked in its blocking position by a vorlösbaren upon actuation of the pawl actuating member to be designated as a blocking lever blocking member.
- the locking lever blocks both in undisturbed normal operation and in the event of a crash, the pawl and releases it only for deflected normal operation.
- the WO 2009/150225 A2 discloses a latch comprising at least one latch with a catch and a pivotable first latch, wherein a trip lever is moved so that the trip lever cooperates with a drive pin of the first latch during its movement and a side pawl spring abuts between the pintle and the trip lever during the interaction , Disclosed is still a motor vehicle door lock, with a locking mechanism, further with a working on the locking mechanism operating lever with a release lever, and with a locking lever which blocks the locking, wherein the locking lever relative to the locking mechanism in normal operation is in blocking position or releases.
- the DE 20 2006 012091 U1 discloses a motor vehicle lock with latch and pawl, wherein the latch can be brought into a main latching position, in a Vorrastrus and in an open position and wherein the pawl in a sunken position in which it holds the latch in the main latching position and in a raised position, in the it releases the latch, is adjustable, wherein the pawl by means of an actuating mechanism in an actuating operation can be lifted and wherein an adjustable locking lever is provided which can be brought into a blocking position and in at least one release position, wherein the blocking lever located in the blocking position (4) a Lifting the pawl (2) blocked.
- the invention is based on the technical problem of finding an alternative locking lever arrangement.
- a generic motor vehicle door lock in the invention is characterized in that the locking lever and the release lever are elastically coupled by at least one spring and connected to each other and the inertia forces of the locking lever occurring in the event of a crash any coupling forces to the trigger more or less clear exceed.
- the locking lever is thus practically in a permanently active state. Because the locking lever stands for the blockage of the locking mechanism in the non-actuated state, so in the event that the motor vehicle door lock is at rest and the locking mechanism is not deflected in a blocking adjustment. Typically, the deflected ratchet in normal operation causes it to be opened. For this purpose, usually the pawl is lifted from the catch.
- the last-described functional state of the locking opening corresponds to the opening normal operation, provided that excessive acceleration forces do not act on the motor vehicle door lock in question.
- the interpretation in the context of the invention is such that the locking lever is in the non-actuated state in Blockadegna.
- D. h. The locking lever does not change its relative position compared to the locking mechanism even in the event of a crash and is contrary to a movement of the locking mechanism. This is essentially due to the fact that the locking lever is balanced in itself, ie the center of gravity is located in the pivot point of the locking lever.
- the locking lever is typically pivotable about an axis pivoting lever.
- the locking lever is usually stored together with the locking mechanism in a lock case, which provides the necessary rigidity and position accuracy to the aforementioned components and their storage.
- the locking lever is usually a two-arm lever with blocking arm and balance arm.
- the locking lever is preferably coupled to the operating lever mechanism.
- the locking lever is connected to a release lever of the operating lever mechanism.
- the release lever works as usual on the locking pawl of the locking mechanism, namely to its opening in a lifting sense. So as soon as the release lever is pivoted to remove the locking pawl of the pawl and lift the pawl of the catch and thus open the locking mechanism, this pivoting movement ensures at the same time that the locking lever is acted upon by the spring. In normal operation, this deflection of the release lever causes the locking lever via the spring between the release lever and the locking lever, as it were "taken” becomes. As a result, the lock lever can not block the lock in the described normal opening operation.
- the moment of inertia of the locking lever is designed so that even the tensioned by the release lever spring between the release lever and the locking lever can not pivot this.
- the locking lever can block the locking mechanism in the event of a crash if the masses of lever mechanism and locking mechanism and the spring coupling the release lever with the locking lever can not overcome the moment of inertia of the locking lever in the tensioned state. As a result, there is practically no relative movement between the blocking pawl and the locking lever in the event of a crash. The locking lever thus ensures in the event of a crash for the desired blockage of the locking mechanism.
- the coupling between on the one hand the locking lever and on the other hand the locking mechanism for example, by a cam, a molding, etc. can take place.
- the locking lever may have the cam in question or a shape that interact with the blocking pawl.
- the reverse can also be done.
- the contour is to be designed so that the blocking pawl rotating in the open direction can not initiate any opening torque into the blocking lever.
- a motor vehicle door lock which initially has a particularly high reliability. Because of the locking mechanism associated with the locking lever is operated at virtually every deflection in normal operation. For this purpose, it is only necessary that the release lever of the actuating lever mechanism is pivoted into the locking mechanism opening sense. In this process, the release lever takes over the intermediate spring with the locking lever, so that as a result, the locking pawl is no longer blocked and can be lifted by the release lever with respect to the catch.
- a motor vehicle door lock which is equipped with a locking mechanism 1, 2, 3 of a rotary latch 1, a locking pawl 2 and a pawl 3.
- a working on the locking mechanism 1, 2, 3 release lever 4 is provided.
- the release lever 4 In order to open the ratchet 1, 2, 3, the release lever 4 must be pivoted about its axis 5 in a clockwise direction, as an arrow drawn in the figure makes clear. As a result, the release lever 4 engages with an edge 6 on a pin 6 'of the blocking pawl 2. As a result, the locking pawl 2 rotates counterclockwise in accordance with the indicated direction of the arrow about its axis 7. Once the locking pawl 2 is lifted from the pawl 3, the catch 1 can pivot about its axis 8 spring assisted clockwise and release a merely indicated locking pin 9. The locking pin 9 is connected to a motor vehicle door, not shown.
- a locking lever 10 which is rotatably mounted about an axis 11.
- the axis 8 of the catch 1, the axis 7 of the blocking pawl 2, the axis 5 of the release lever 4 and finally the axis 11 of the locking lever 10 are defined in total in a lock case 12.
- it may in each case be bearing journals which are aligned substantially parallel to one another and for the most part stand upright on a base surface of the lock case 12. This is of course only to be understood as illustrative and not restrictive.
- the locking lever 10 is formed as pivotable about its axis 11 pivot lever 10. As already explained, the locking lever 10 is mounted together with the locking mechanism 1, 2, 3 in the lock case 12.
- the locking lever 10 is a two-arm lever with a blocking arm 10a and a balance arm 10b.
- the blocking arm 10a represents the blocking pawl 2 facing arm of the locking lever 10, whereas the compensating arm 10b of the blocking pawl 2 faces away.
- the blocking arm 10a is equipped with a recess or recess 13 in which an edge 13 'of the blocking pawl 2 engages.
- the reverse can also be done.
- the blocking pawl 2 has a molding 13 and the locking lever 10 is equipped with a corresponding edge 13 '.
- the locking lever 10 is conceivable and is encompassed by the invention. Either way, the locking lever 10 in the normal operation shown in the figure ensures that the locking pawl 2 is blocked in the event of a crash and can not perform the direction indicated in the opening case counterclockwise movement about the axis 7, which is initiated by the release lever 4 during its operation , In other words, the locking mechanism 1, 2, 3 is blocked because the blocking pawl 2 experiences the blockage described by the locking lever 10.
- the locking lever 10 is coupled to the release lever 4.
- an elastic coupling in the form of a spring 14 is provided at this point.
- This spring 14 connects the locking lever 10 and the release lever 4 with each other.
- the spring 14 preferably engages the blocking arm 10a of the blocking lever 10.
- the design in the exemplary embodiment is such that the release lever 4 and the locking pawl 2 are arranged with their respective axes 5, 7 on a connecting line and, in contrast, the locking lever 10 is located below its arrangement. D. h., The locking lever 10 is placed below the connecting line through the two axes 5, 7 on the one hand the trigger lever 4 and on the other hand, the blocking pawl 2.
- the actuating edge 6 acting on the blocking pawl 2 ensures that the blocking pawl 2 completes the counterclockwise movement indicated in the figure about its axis 7. Subsequently, the pawl 3 can be lifted from the catch 1, which in turn opens spring-assisted and releases the previously captured locking pin 9. For this corresponds to the normal operation, in which the locking lever 10, the locking mechanism 1, 2, 3 and the blocking pawl 2 releases.
- a spring, not shown, on the blocking lever 10 ensures that the blocking lever with the movement of the Release lever 4 in the starting position also in the non-actuated state, the rest position is returned.
- the trigger lever 4 can be deflected depending on the acceleration forces occurring and depending on the direction of force. That is, the trip lever 4 would experience a comparable clockwise action about its axis 5 as in a "normal” operation. In contrast to this "normal” operation but in the event of a crash on the locking lever 10 and also blocked by him blocking pawl 2 act inertial forces.
- the moment of inertia of the locking lever 10 is designed so that in the described crash case, there is no relative movement of the locking lever 10 and the blocker latch 2 is blocked by the locking lever 10.
- the design is such that the deflected in the assumed crash case release lever 4 with the thus tensioned spring 14, the locking lever 10 also can not deflect and the blockage of the locking mechanism 1, 2, 3 thus occurs.
Description
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit einem Gesperre, ferner mit einem auf das Gesperre arbeitenden Betätigungshebelwerk mit Auslösehebel, und mit einem Sperrhebel, welcher das Gesperre zumindest bei auftretenden Beschleunigungskräften vorgegebener Größe, beispielsweise bei einem Unfall ("Crash-Fall"), blockiert.The invention relates to a motor vehicle door lock, with a locking mechanism, also with a working on the ratchet operating lever mechanism with release lever, and with a locking lever which blocks the ratchet at least when occurring acceleration forces of predetermined size, for example in an accident ("crash").
Ein Betätigungshebelwerk, setzt sich in der Regel aus einem oder mehreren Hebeln zusammen. Üblicherweise kommen ein Innbetätigungshebel, ein Außenbetätigungshebel und ein Auslösehebel im Minimum zum Einsatz. Darüber hinaus umfasst das Betätigungshebelwerk oftmals auch einen Kupplungshebel. Wird das Betätigungshebelwerk beaufschlagt, kann auf diese Weise das Gesperre geöffnet werden. Zu diesem Zweck greift typischerweise der Auslösehebel an einer Sperrklinke des Gesperres an und hebt diese von einer zugehörigen Drehfalle ab. Die Drehfalle öffnet sich daraufhin federunterstützt und gibt einen zuvor gefangenen Schließbolzen frei. Dadurch kann eine zugehörige Kraftfahrzeugtür geöffnet werden.An operating lever mechanism is usually composed of one or more levers. Usually, an Innbetätigungshebel, an external operating lever and a release lever are used in the minimum. In addition, the operating lever mechanism often also includes a clutch lever. If the actuating lever mechanism is acted upon, the locking mechanism can be opened in this way. For this purpose, typically the release lever engages a pawl of the ratchet and lifts it from an associated catch. The catch then opens spring-assisted and releases a previously captured locking pin. As a result, an associated motor vehicle door can be opened.
Bei einem Unfall respektive dem zuvor bereits angesprochenen "Crash-Fall" treten meistens hohe Beschleunigungskräfte auf, welche ein Mehrfaches der Erdbeschleunigung betragen können. Dadurch ist der betreffende Kraftfahrzeugtürverschluss erheblichen Massekräften ausgesetzt, welche zu einem ungewollten Öffnen des Gesperres und folglich eines gesamten zugehörigen Türschlosses führen können.In an accident or the previously mentioned "crash case" usually occur high acceleration forces, which may amount to a multiple of the acceleration due to gravity. As a result, the motor vehicle door lock in question is exposed to considerable mass forces, which can lead to an unwanted opening of the locking mechanism and consequently of an entire associated door lock.
Aufgrund der beschriebenen Szenarien ergeben sich erhebliche Gefahren für Fahrzeugbenutzer. Denn eine beispielsweise unbeabsichtigt geöffnete Kraftfahrzeugtür kann die in ihr vorhandenen Sicherheitseinrichtungen wie beispielsweise einen Seitenairbag oder auch Seitenaufprallschutz nicht mehr für den Schutz der Fahrzeuginsassen zur Verfügung stellen. Aus diesem Grund hat man in der Vergangenheit bereits verschiedene Maßnahmen ergriffen, welche beim Auftreten der beschriebenen abnormalen Beschleunigungskräfte, d. h. im Crash-Fall, entweder das Betätigungshebelwerk oder das Gesperre blockieren. Dabei kann eine sogenannte Massensperre zum Einsatz, welche sich unter normalen Betriebsbedingungen in ihrer Ruhelage befindet und außer Eingriff mit dem Betätigungshebelwerk respektive dem Gesperre ist.Due to the described scenarios, considerable risks for vehicle users arise. For example, an unintentionally opened motor vehicle door can no longer provide the existing safety devices such as a side airbag or side impact protection for the protection of the vehicle occupants. For this reason, various measures have already been taken in the past, which at the occurrence of the described abnormal acceleration forces, d. H. in the event of a crash, block either the operating lever mechanism or the locking mechanism. In this case, a so-called mass barrier is used, which is under normal operating conditions in its rest position and out of engagement with the operating lever mechanism respectively the locking mechanism.

Der Erfindung liegt das technische Problem zugrunde, eine alternative Sperrhebelanordnung zu finden.The invention is based on the technical problem of finding an alternative locking lever arrangement.
Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Kraftfahrzeugtürverschluss im Rahmen der Erfindung dadurch gekennzeichnet, dass der Sperrhebel und der Auslösehebel durch zumindest eine Feder elastisch gekoppelt und miteinander verbunden sind und die beim Crash-fall auftretenden Trägheitskräfte des Sperrhebels etwaige Koppelkräfte zum Auslösehebel mehr oder minder deutlich überschreiten.To solve this technical problem, a generic motor vehicle door lock in the invention is characterized in that the locking lever and the release lever are elastically coupled by at least one spring and connected to each other and the inertia forces of the locking lever occurring in the event of a crash any coupling forces to the trigger more or less clear exceed.
Im Rahmen der Erfindung befindet sich der Sperrhebel also praktisch in einem daueraktiven Zustand. Denn der Sperrhebel steht für die Blockade des Gesperres im nicht betätigtem Zustand, also für den Fall, dass der Kraftfahrzeugtürverschluss in Ruhe ist und das Gesperre nicht ausgelenkt wird in einer Blockierverstellung. Typischerweise führt das ausgelenkte Gesperre im Normalbetrieb dazu, dass dieses geöffnet wird. Zu diesem Zweck wird meist die Sperrklinke von der Drehfalle abgehoben.In the context of the invention, the locking lever is thus practically in a permanently active state. Because the locking lever stands for the blockage of the locking mechanism in the non-actuated state, so in the event that the motor vehicle door lock is at rest and the locking mechanism is not deflected in a blocking adjustment. Typically, the deflected ratchet in normal operation causes it to be opened. For this purpose, usually the pawl is lifted from the catch.
Der zuletzt beschriebene Funktionszustand der Gesperreöffnung korrespondiert zum öffnenden Normalbetrieb, sofern keine übermäßigen Beschleunigungskräfte an dem fraglichen Kraftfahrzeugtürverschluss angreifen.The last-described functional state of the locking opening corresponds to the opening normal operation, provided that excessive acceleration forces do not act on the motor vehicle door lock in question.
Jedenfalls ist die Auslegung im Rahmen der Erfindung so getroffen, dass sich der Sperrhebel in nicht betätigtem Zustand im Blockadestellung befindet. Das Gleiche gilt für den Crash-Fall. D. h., der Sperrhebel ändert seine Relativposition im Vergleich zum Gesperre selbst im Crash-Fall nicht und steht einer Bewegung des Gesperres sperrend entgegen. Das lässt sich im Wesentlichen darauf zurückführen, dass der Sperrhebel in sich ausgeglichen ist, d.h. der Schwerpunkt sich im Drehpunkt des Sperrhebels befindet.In any case, the interpretation in the context of the invention is such that the locking lever is in the non-actuated state in Blockadestellung. The The same applies to the crash case. D. h., The locking lever does not change its relative position compared to the locking mechanism even in the event of a crash and is contrary to a movement of the locking mechanism. This is essentially due to the fact that the locking lever is balanced in itself, ie the center of gravity is located in the pivot point of the locking lever.
Im Detail handelt es sich bei dem Sperrhebel typischerweise als um eine Achse drehbaren Schwenkhebel. Dabei ist der Sperrhebel meistens zusammen mit dem Gesperre in einem Schlosskasten gelagert, welcher den vorerwähnten Bauteilen und ihrer Lagerung die nötige Steifigkeit und Positionsgenauigkeit zur Verfügung stellt. Bei dem Sperrhebel handelt es sich im Regelfall um einen Zweiarmhebel mit Blockadearm und Ausgleichsarm. Außerdem ist der Sperrhebel vorzugsweise mit dem Betätigungshebelwerk gekoppelt.In detail, the locking lever is typically pivotable about an axis pivoting lever. In this case, the locking lever is usually stored together with the locking mechanism in a lock case, which provides the necessary rigidity and position accuracy to the aforementioned components and their storage. The locking lever is usually a two-arm lever with blocking arm and balance arm. In addition, the locking lever is preferably coupled to the operating lever mechanism.
An dieser Stelle hat sich besonders eine elastische Kopplung als günstig erwiesen. Diese wird meistens durch eine Feder zur Verfügung gestellt, welche den Sperrhebel und das Betätigungshebelwerk miteinander verbindet. Im Regelfall greift die betreffende Feder an dem Blockadearm des Sperrhebels an, immer so, dass der Sperrheben im Normalbetrieb ausgelenkt wird und dadurch dass Gesperre frei gibt.At this point, especially an elastic coupling has proven to be favorable. This is usually provided by a spring, which connects the locking lever and the operating lever work together. As a rule, the spring in question acts on the blocking arm of the blocking lever, always in such a way that the blocking lifting is deflected during normal operation and thus that locking mechanism is released.
Im Detail ist der Sperrhebel mit einem Auslösehebel des Betätigungshebelwerkes verbunden. Der Auslösehebel arbeitet wie üblich auf die Blockierklinke des Gesperres, und zwar zu seiner Öffnung in aushebendem Sinne. Sobald also der Auslösehebel verschwenkt wird, um die Blockierklinke von der Sperrklinke zu entfernen und die Sperrklinke von der Drehfalle abzuheben und damit das Gesperre zu öffnen, sorgt diese Schwenkbewegung zugleich dafür, dass der Sperrhebel von der Feder beaufschlagt wird. Im Normalbetrieb führt diese Auslenkung des Auslösehebels dazu, dass der Sperrhebel über die Feder zwischen dem Auslösehebel und dem Sperrhebel gleichsam "mitgenommen" wird. Als Folge hiervon kann der Sperrhebel das Gesperre in dem beschriebenen öffnenden Normalbetrieb nicht blockieren.In detail, the locking lever is connected to a release lever of the operating lever mechanism. The release lever works as usual on the locking pawl of the locking mechanism, namely to its opening in a lifting sense. So as soon as the release lever is pivoted to remove the locking pawl of the pawl and lift the pawl of the catch and thus open the locking mechanism, this pivoting movement ensures at the same time that the locking lever is acted upon by the spring. In normal operation, this deflection of the release lever causes the locking lever via the spring between the release lever and the locking lever, as it were "taken" becomes. As a result, the lock lever can not block the lock in the described normal opening operation.
Im Normalbetrieb bei nicht betätigtem Zustand liegt der Sperrhebel dagegen in Blockierposition an der Blockierklinke lose an und blockiert diese im Crash-Fall. Dafür sorgt eine Feder, die den Sperrhebel nach dem Auslenken wieder in die Normalstellung für den nicht betätigten Zustand zurückführt.In normal operation when not actuated state, however, the locking lever is loosely in the blocking position on the blocking pawl and blocks it in the event of a crash. This is ensured by a spring, which returns the locking lever after the deflection back into the normal position for the non-actuated state.
Denn die mit einem solchen Crash-Fall verbundenen Beschleunigungen führen im Regelfall dazu, dass das Betätigungshebelwerk ausgelenkt wird und auch der Auslösehebel eine Auslenkung erfährt, als ob die Sperrklinke von der Drehfalle abgehoben werden soll. Das Masseverträgkeitsmoment des Sperrhebels sorgt jedoch dafür, dass der Sperrhebel der Auslenkung des Auslösehebels in diesem Crash-Fall nicht folgt. Vielmehr verbleibt der Sperrhebel zusammen mit der Blockierklinke, die aufgrund des Crashes gegen den Blockierhebel drückt, unverändert in seiner Blockierposition.Because the accelerations associated with such a crash case usually cause the Betätigungshebelwerk is deflected and the release lever undergoes a deflection, as if the pawl is to be lifted from the catch. However, the Masseverträgkeitsmoment the locking lever ensures that the locking lever does not follow the deflection of the trigger lever in this crash case. Rather, the locking lever remains together with the blocking pawl, which presses due to the crash against the blocking lever, unchanged in its blocking position.
Dabei ist das Massenträgheitsmoment des Sperrhebels so ausgelegt, dass selbst die durch den Auslösehebel gespannte Feder zwischen dem Auslösehebel und dem Sperrhebel diesen nicht verschwenken kann.In this case, the moment of inertia of the locking lever is designed so that even the tensioned by the release lever spring between the release lever and the locking lever can not pivot this.
Jedenfalls wird deutlich, dass der Sperrhebel das Gesperre im Crash-Fall blockieren kann, wenn die Massen von Hebelwerk und Gesperre und die den Auslösehebel mit dem Sperrhebel koppelnde Feder in gespanntem Zustand des Trägheitsmoment des Sperrhebels nicht überwinden können. Dadurch findet zwischen der Blockierklinke und dem Sperrhebel im Crash-Fall praktisch keine Relativbewegung statt. Der Sperrhebel sorgt also im Crash-Fall für die gewünschte Blockade des Gesperres.In any case, it is clear that the locking lever can block the locking mechanism in the event of a crash if the masses of lever mechanism and locking mechanism and the spring coupling the release lever with the locking lever can not overcome the moment of inertia of the locking lever in the tensioned state. As a result, there is practically no relative movement between the blocking pawl and the locking lever in the event of a crash. The locking lever thus ensures in the event of a crash for the desired blockage of the locking mechanism.
Nach weiterer vorteilhafter Ausgestaltung ist vorgesehen, dass die Kopplung zwischen einerseits dem Sperrhebel und andererseits dem Gesperre beispielsweise durch einen Nocken, eine Ausformung etc. erfolgen kann. Dazu mag der Sperrhebel den betreffenden Nocken oder eine Ausformung aufweisen, die jeweils mit der Blockierklinke wechselwirken. Selbstverständlich kann auch umgekehrt vorgegangen werden. In diesem Fall ist nicht der Sperrhebel, sondern vielmehr die Blockierklinke respektive das Gesperre mit den fraglichen Nocken , der Ausformung etc. ausgerüstet. Die Kontur ist dabei so auszuführen, dass die in Offen-Richtung drehende Blockierklinke kein öffnendes Drehmoment in den Sperrhebel einleiten kann.According to a further advantageous embodiment, it is provided that the coupling between on the one hand the locking lever and on the other hand the locking mechanism for example, by a cam, a molding, etc. can take place. For this purpose, the locking lever may have the cam in question or a shape that interact with the blocking pawl. Of course, the reverse can also be done. In this case, not the locking lever, but rather the locking pawl respectively the locking mechanism with the cams in question, the molding etc. equipped. The contour is to be designed so that the blocking pawl rotating in the open direction can not initiate any opening torque into the blocking lever.
Im Ergebnis wird ein Kraftfahrzeugtürverschluss zur Verfügung gestellt, der zunächst einmal über eine besonders hohe Funktionssicherheit verfügt. Denn der dem Gesperre zugeordnete Sperrhebel wird praktisch bei jeder Auslenkung im Normalbetrieb betätigt. Hierzu ist es lediglich erforderlich, dass der Auslösehebel des Betätigungshebelwerkes in das Gesperre öffnendem Sinne verschwenkt wird. Bei diesem Vorgang nimmt der Auslösehebel über die zwischengeschaltete Feder den Sperrhebel mit, so dass als Folge hiervon die Blockierklinke nicht mehr blockiert ist und von dem Auslösehebel in Bezug auf die Drehfalle abgehoben werden kann.As a result, a motor vehicle door lock is provided, which initially has a particularly high reliability. Because of the locking mechanism associated with the locking lever is operated at virtually every deflection in normal operation. For this purpose, it is only necessary that the release lever of the actuating lever mechanism is pivoted into the locking mechanism opening sense. In this process, the release lever takes over the intermediate spring with the locking lever, so that as a result, the locking pawl is no longer blocked and can be lifted by the release lever with respect to the catch.
Diese gleichsam bei jedem Öffnungsvorgang des Gesperres stattfindende Bewegung des Sperrhebels stellt sicher, dass seine Funktionsfähigkeit praktisch derjenigen des gesamten Kraftfahrzeugtürverschlusses entspricht. Etwaige Funktionsstörungen durch Korrosion etc. treten erfindungsgemäß ausdrücklich nicht (mehr) auf. Das alles wird erreicht mit einem einfachen und auf wenige Elemente beschränkten Aufbau, der sich demzufolge kostengünstig und schnell realisieren lässt. Hierin sind die wesentlichen Vorteile zu sehen.This movement of the locking lever, which, as it were, takes place during each opening process of the locking mechanism, ensures that its functionality practically corresponds to that of the entire motor vehicle door lock. Any malfunction due to corrosion, etc., according to the invention are expressly not (anymore). All this is achieved with a simple and limited to a few elements construction, which can therefore be realized quickly and inexpensively. Here are the main benefits.
Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Die einzige Figur zeigt den erfindungsgemäßen Kraftfahrzeugtürverschluss schematisch.In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. The single figure shows the motor vehicle door lock according to the invention schematically.
In der Figur ist ein Kraftfahrzeugtürverschluss dargestellt, der mit einem Gesperre 1, 2, 3 aus einer Drehfalle 1, einer Blockierklinke 2 und einer Sperrklinke 3 ausgerüstet ist. Darüber hinaus ist ein auf das Gesperre 1, 2, 3 arbeitendes Auslösehebel 4 vorgesehen.In the figure, a motor vehicle door lock is shown, which is equipped with a
Um das Gesperre 1, 2, 3 zu öffnen, muss der Auslösehebel 4 um seine Achse 5 im Uhrzeigersinn verschwenkt werden, wie ein in der Figur eingezeichneter Pfeil deutlich macht. Dadurch greift der Auslösehebel 4 mit einer Kante 6 an einem Zapfen 6' der Blockierklinke 2 an. Als Folge hiervon dreht sich die Blockierklinke 2 im Gegenuhrzeigersinn entsprechend der angedeuteten Pfeilrichtung um ihre Achse 7. Sobald die Blockierklinke 2 von der Sperrklinke 3 abgehoben ist, kann die Drehfalle 1 um ihre Achse 8 federunterstützt im Uhrzeigersinn aufschwenken und einen lediglich angedeuteten Schließbolzen 9 freigeben. Der Schließbolzen 9 ist an eine nicht dargestellte Kraftfahrzeugtür angeschlossen.In order to open the
Zum weiteren grundsätzlichen Aufbau gehört ein Sperrhebel 10, welcher um eine Achse 11 drehbar gelagert ist. Die Achse 8 der Drehfalle 1, die Achse 7 der Blockierklinke 2, die Achse 5 des Auslösehebels 4 und schließlich die Achse 11 des Sperrhebels 10 sind insgesamt in einem Schlosskasten 12 definiert. Dabei mag es sich jeweils um Lagerzapfen handeln, die im Wesentlichen parallel zueinander ausgerichtet sind und größtenteils senkrecht auf einer Grundfläche des Schlosskastens 12 aufstehen. Das ist selbstverständlich nur beispielhaft und nicht einschränkend zu verstehen.For further basic structure includes a locking
Der Sperrhebel 10 ist als um seine Achse 11 drehbarer Schwenkhebel 10 ausgebildet. Wie bereits erläutert, ist der Sperrhebel 10 zusammen mit dem Gesperre 1, 2, 3 in dem Schlosskasten 12 gelagert. Bei dem Sperrhebel 10 handelt es sich um einen Zweiarmhebel mit einem Blockadearm 10a und einem Ausgleichsarm 10b.The locking
Der Blockadearm 10a stellt den der Blockierklinke 2 zugewandten Arm des Sperrhebels 10 dar, wohingegen der Ausgleichsarm 10b der Blockierklinke 2 abgewandt ist. Im Ausführungsbeispiel ist der Blockadearm 10a mit einer Ausnehmung respektive Ausformung 13 ausgerüstet, in welche eine Kante 13' der Blockierklinke 2 eingreift. Selbstverständlich kann auch umgekehrt vorgegangen werden. Dann verfügt die Blockierklinke 2 über eine Ausformung 13 und ist der Sperrhebel 10 mit einer korrespondierenden Kante 13' ausgerüstet.The blocking arm 10a represents the blocking
Auch ein Nocken an einerseits der Blockierklinke 2 oder andererseits dem Sperrhebel 10 ist denkbar und wird von der Erfindung umfasst. So oder so sorgt der Sperrhebel 10 in dem in der Figur dargestellten Normalbetrieb dafür, dass die Blockierklinke 2 im Crash-Fall blockiert ist und nicht die im Öffnungsfall angedeutete Gegenuhrzeigersinnbewegung um die Achse 7 vollführen kann, die von dem Auslösehebel 4 bei seiner Betätigung initiiert wird. Anders ausgedrückt, wird das Gesperre 1, 2, 3 blockiert, weil die Blockierklinke 2 durch den Sperrhebel 10 die beschriebene Blockade erfährt.A cam on the one hand the blocking
Man erkennt, dass der Sperrhebel 10 mit dem Auslösehebel 4 gekoppelt ist. Tatsächlich ist an dieser Stelle eine elastische Kopplung in Gestalt einer Feder 14 vorgesehen. Diese Feder 14 verbindet den Sperrhebel 10 und den Auslösehebel 4 miteinander. Dabei greift die Feder 14 vorzugsweise am Blockadearm 10a des Sperrhebels 10 an.It can be seen that the locking
Schließlich ist die Auslegung im Ausführungsbeispiel so getroffen, dass der Auslösehebel 4 und die Blockierklinke 2 mit ihren jeweiligen Achsen 5, 7 auf einer Verbindungslinie angeordnet sind und demgegenüber der Sperrhebel 10 darunter seine Anordnung findet. D. h., der Sperrhebel 10 ist unterhalb der Verbindungslinie durch die beiden Achsen 5, 7 von einerseits dem Auslösehebel 4 und andererseits der Blockierklinke 2 platziert.Finally, the design in the exemplary embodiment is such that the
Die Funktionsweise ist wie folgt. In der dargestellten Figur befindet sich das Gesperre 1, 2, 3 in geschlossenem Zustand. Die Sperrklinke 3 ist in die Drehfalle 1 eingefallen. Die Drehfalle 1 nimmt ihre Hauptraststellung ein. Außerdem wird in der Fig. der nicht betätigten Zustand, die Ruhestellung dargestellt.The operation is as follows. In the illustrated figure, the
Sobald in dieser Stellung und bei nicht auftretenden abnormalen Beschleunigungen, d.h. in Normalfall, der Auslösehebel 4 in der Weise beaufschlagt wird, dass um seine Achse 5 die angedeutete Uhrzeigersinnbewegung vollführt, sorgt diese Schwenkbewegung des Auslösehebels 4 dafür, dass der Sperrhebel 10 um seine Achse 11 ebenfalls verschwenkt wird. Das stellt die den Auslösehebel 4 mit dem Sperrhebel 10 koppelnde Feder 14 sicher. Bei diesem Vorgang erfährt der Sperrhebel 10 eine Schwenkbewegung um seine Achse 11, und zwar im Gegenuhrzeigersinn, wie ein Pfeil in der Figur andeutet (Öffnungsfall).Once in this position and in the absence of abnormal accelerations, i. In normal case, the
D. h., ausgehend vom Normalbetrieb bewegen sich bei der Auslenkung des Auslösehebels 4 der Auslösehebel 4 und der Sperrhebel 10 gleichsam synchron. Bei diesem Vorgang gibt der Sperrhebel 10 die zuvor blockierte Blockierklinke 2 frei. Dadurch kann der Auslösehebel 4 bei fortgesetzter Bewegung mit seiner Betätigungskante 6 die Blockierklinke 2 bzw. deren Zapfen 6' beaufschlagen.D. h., Starting from normal operation to move in the deflection of the
Als Folge hiervon sorgt die an der Blockierklinke 2 angreifende Betätigungskante 6 dafür, dass die Blockierklinke 2 die in der Figur angedeutete Gegenuhrzeigersinnbewegung um ihre Achse 7 vollzieht. Nachfolgend kann die Sperrklinke 3 von der Drehfalle 1 abgehoben werden, welche ihrerseits federunterstützt öffnet und den zuvor gefangenen Schließbolzen 9 freigibt. Hierzu korrespondiert der Normalbetrieb, in welchem der Sperrhebel 10 das Gesperre 1, 2, 3 bzw. die Blockierklinke 2 freigibt.As a result, the actuating edge 6 acting on the blocking
Bei der Schließung des Gesperres 1, 2, 3 sorgt eine nicht dargestellte Feder am Blockierhebel 10 dafür, dass der Blockierhebel mit der Bewegung des Auslösehebels 4 in die Ausgangsposition ebenfalls in den nicht betätigtem Zustand, die Ruhestellung zurückgeführt wird.At the closure of the
Kommt es ausgehend von dem Normalbetrieb entsprechend der in der Figur dargestellten Funktionsstellung zu einem Crash-Fall, so kann hierbei der Auslösehebel 4 je nach auftretenden Beschleunigungskräften und je nach Kraftrichtung ausgelenkt werden. D. h., der Auslösehebel 4 würde eine vergleichbare Beaufschlagung im Uhrzeigersinn um seine Achse 5 wie bei einer "normalen" Betätigung erfahren. Im Unterschied zu dieser "normalen" Betätigung wirken jedoch im Crashfall auf den Sperrhebel 10 und auch die von ihm blockierte Blockierklinke 2 Trägheitskräfte ein. Das Massenträgheitsmoment des Sperrhebels 10 ist so ausgeführt, dass in dem beschriebenen Crash-Fall es zu keiner Relativbewegung des Sperrhebels 10 kommt und die Blockerklinke 2 durch den Sperrhebel 10 blockiert wird.If it comes from the normal operation according to the functional position shown in the figure to a crash case, so here the
Außerdem ist die Auslegung so getroffen, dass der in dem angenommenen Crash-Fall ausgelenkte Auslösehebel 4 mit der dadurch gespannten Feder 14 den Sperrhebel 10 ebenfalls nicht auslenken kann und die Blockade des Gesperres 1, 2, 3 folglich eintritt.In addition, the design is such that the deflected in the assumed crash
