Description

Die Erfindung betrifft ein Kraftfahrzeugtürschloss, mit zumindest einem Gehäuse aus Kunststoff, und mit einem Gesperre aus im Wesentlichen Drehfalle und Sperrklinke.The invention relates to a motor vehicle door lock, with at least one housing made of plastic, and with a locking mechanism consisting essentially of a catch and a pawl.

Solche Kraftfahrzeugtürschlösser sind vielfältig aus der Praxis bekannt und werden beispielhaft in der gattungsbildenden DE 10 2009 042 630 A1 in Bezug genommen. Hier erkennt man das Kraftfahrzeugtürschloss in Explosionsdarstellung. Dazu verfügt das Kraftfahrzeugtürschloss über das bereits angesprochene Gehäuse aus Kunststoff sowie zusätzlich einen Schlosskasten aus Metall, welcher für die Lagerung des Gesperres aus im Wesentlichen Drehfalle und Sperrklinke sorgt. Der Schlosskasten aus Metall ist im Allgemeinen erforderlich, um die am Gesperre wirkenden Kräfte - auch und insbesondere bei einem Unfall - aufnehmen zu können. Das hat sich grundsätzlich bewährt.Such motor vehicle door locks are widely known from practice and are exemplary in the generic DE 10 2009 042 630 A1 referenced. Here you can see the motor vehicle door lock in an exploded view. For this purpose, the motor vehicle door lock on the already mentioned housing made of plastic and in addition a lock case made of metal, which provides for the storage of the locking mechanism of substantially rotary latch and pawl. The metal lock case is generally required in order to absorb the forces acting on the locking mechanism - also and in particular in an accident - can. This has proven itself in principle.

Tatsächlich wirkt das Gesperre des Kraftfahrzeugtürschlosses typischerweise mit einem Schließbolzen an beispielsweise einer B-Säule einer Kraftfahrzeugkarosserie zusammen. Das Kraftfahrzeugtürschloss ist meistens innenseitig einer Kraftfahrzeugtür angeordnet. Auf diese Weise wird insgesamt ein Kraftfahrzeugtürverschluss zur Verfügung gestellt. Wie im Stand der Technik nach der DE 10 2009 042 630 A1 beschrieben und zeichnerisch dargestellt, ist das Gehäuse aus Kunststoff meistens zweiteilig ausgelegt und verfügt über eine das Gehäuse verschließende Gehäusehaube.In fact, the locking mechanism of the motor vehicle door lock typically interacts with a locking bolt on, for example, a B-pillar of a motor vehicle body. The motor vehicle door lock is usually arranged inside a motor vehicle door. In this way, a total of a motor vehicle door lock is provided. As in the prior art after DE 10 2009 042 630 A1 described and illustrated in the drawing, the plastic housing is usually designed in two parts and has a housing capping housing cover.

Als Folge hiervon sind die Kraftfahrzeugtürschlosser nach dem Stand der Technik regelmäßig mit dem bereits angesprochenen Schlosskasten aus Metall und dem zweiteiligen Gehäuse mit beispielsweise Gehäuseunterteil und Gehäuseoberteil respektive dem eigentlichen Gehäuse bzw. einer Gehäuseschale und einer Gehäusehaube ausgerüstet. Daraus resultiert ein relativ komplexer und insbesondere kostenträchtiger Aufbau aus wenigstens drei Strukturelementen (Schlosskasten, Gehäuseunterteil bzw. Gehäuse und Gehäuseoberteil bzw. Gehäusehaube).As a result, the motor vehicle door locksmith according to the prior art are regularly equipped with the already mentioned lock case made of metal and the two-piece housing with, for example, housing base and housing top respectively the actual housing or a housing shell and a housing cover. This results in a relatively complex and costly construction of at least three structural elements (Lock case, housing base or housing and housing upper part or housing cover).

Hinzu kommt, dass die Drehfalle zum Eingriff mit dem Schließbolzen im Bereich eines Einlaufschlitzes angeordnet werden muss, der eine zwangsläufige Öffnung im Kraftfahrzeugtürschloss erfordert. Durch diese Öffnung kann Schmutz oder auch Feuchtigkeit eindringen. Zwar arbeitet man an dieser Stelle üblicherweise mit Dichtungen. Diese können jedoch Umwelteinflüsse nicht fernhalten. Das gilt auch für die mit der Drehfalle wechselwirkende Sperrklinke. Hier will die Erfindung insgesamt Abhilfe schaffen.In addition, the catch must be arranged for engagement with the locking pin in the region of an inlet slot, which requires a positive opening in the motor vehicle door lock. Through this opening dirt or moisture can penetrate. Although it works at this point usually with seals. However, these can not keep environmental influences off. This also applies to the ratchet interacting with the catch. Here, the invention aims to provide a total remedy.

Ferner offenbaren die EP 0 894 926 A1 und die DE 10 2004 001988 A1 einen Kraftfahrzeugtürverschluss mit einem Gehäuse und einem im Gehäuse gelagerten Gesperre aus Drehfalle und Sperrklinke. In dem Kraftfahrzeugtürverschluss der EP 0 894 926 A1 ist zudem die Sperrklinke innerhalb des Gehäuses in einem teilweise abgetrennten Kammer gelagert.Furthermore, the EP 0 894 926 A1 and the DE 10 2004 001988 A1 a motor vehicle door lock with a housing and a mounted in the housing catch of catch and pawl. In the motor vehicle door lock the EP 0 894 926 A1 In addition, the pawl is mounted within the housing in a partially separated chamber.

Der Erfindung liegt die technische Aufgabe zugrunde, ein derartiges Kraftfahrzeugtürschloss so weiter zu entwickeln, dass eine hohe Funktionsfähigkeit bei zugleich einfacherem und folglich kostengünstigeren Aufbau im Vergleich zu bisherigen Lösungen gegeben ist.The invention is based on the technical problem of developing such a motor vehicle door lock so that a high level of functionality is given at the same time simpler and therefore more cost-effective structure compared to previous solutions.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßes Kraftfahrzeugtürschloss im Rahmen der Erfindung dadurch gekennzeichnet, dass die Sperrklinke auf einem einstückig an das Gehäuse angeformten Sperrklinken-Lagerbolzen drehbar um eine zugehörige Achse gelagert.. Der Sperrklinken-Lagerbolzen und das Gehäuse werden meistens in einem gemeinsamen Vorgang hergestellt. Hierbei kann es sich um ein Kunststoffspritzgussverfahren und/oder ein Metalldruckgussverfahren handeln. Grundsätzlich kann der Sperrklinken-Lagerbolzen auch mit einer eingebetteten Verstärkung ausgerüstet werden. Aufgrund der einstückigen Anformung des Sperrklinken-Lagerbolzens an das Gehäuse wird meistens auf ein und denselben Kunststoff zur Realisierung des Gehäuses einerseits und des Sperrklinken-Lagerbolzens andererseits zurückgegriffen. Dadurch lässt sich der Sperrklinken-Lagerbolzen besonders einfach und kostengünstig realisieren, nämlich in einem Zug mit dem Gehäuse. Anders ausgedrückt, ist ein separater Sperrklinken-Lagerbolzen beispielsweise aus Metall und dessen Anbringung am oder im Gehäuse entbehrlich.To solve this technical problem, a generic motor vehicle door lock in the invention is characterized in that the pawl rotatably mounted on an integrally formed on the housing pawl-bearing pin about an associated axis .. The pawl-bearing pin and the housing are usually in a common process produced. This may be a plastic injection molding process and / or a metal die casting process. Basically, the pawl bearing pin can also be equipped with an embedded reinforcement. Due to the one-piece molding of the pawl bearing pin to the housing is usually resorted to one and the same plastic for the realization of the housing on the one hand and the pawl bearing pin on the other. As a result, the pawl-bearing pin can be particularly simple and inexpensive to implement, namely in one go with the housing. In other words, a separate pawl-bearing bolt, for example made of metal and its attachment to or in the housing is unnecessary.

Im erfindungsgemäßen Kraftfahrzeugtürschloss ist die Sperrklinke im Innern des Gehäuses aus Kunststoff und die Drehfalle außerhalb am Gehäuse gelagert, wodurch das Gehäuse aus Kunststoff folglich als wesentliches und tragendes Strukturelement fungiert, ersetzt also den Schlosskasten aus Metall und wenigstens das Gehäuseunterteil bzw. die Gehäuseschale respektive führt diese beiden Strukturelemente zusammen. Denn das Gehäuse aus Kunststoff fungiert gleichsam als Lagerplatte für einerseits die Sperrklinke und andererseits die Drehfalle. Dabei ist die Sperrklinke im Innern des Gehäuses gelagert, wohingegen die Drehfalle im Rahmen der Erfindung eine Lagerung außerhalb am Gehäuse erfährt.In the motor vehicle door lock according to the invention, the pawl inside the housing made of plastic and the catch is mounted outside the housing, whereby the plastic housing thus acts as an essential and supporting structural element, thus replacing the lock case made of metal and at least the housing base or the housing shell respectively leads them two structural elements together. Because the plastic housing acts as a kind of bearing plate for on the one hand the pawl and on the other hand, the catch. In this case, the pawl is mounted in the interior of the housing, whereas the catch under the invention undergoes a bearing outside the housing.

Die Lagerung der Drehfalle außen am Gehäuse trägt dem Umstand Rechnung, dass die Drehfalle auf diese Weise unschwer mit dem Schließbolzen wechselwirken kann. Zugleich ist hierdurch die Funktionssicherheit gesteigert, weil lediglich die Drehfalle im mit Feuchtigkeit, Schmutz etc. belasteten Außenbereich eine Anordnung erfährt, demgegenüber die Sperrklinke geschützt im Innern des Gehäuses angeordnet und gelagert wird.The bearing of the catch outside of the housing takes into account the fact that the catch can interact easily with the locking pin in this way. At the same time thereby the reliability is increased, because only the rotary latch in the loaded with moisture, dirt, etc. outside area undergoes an arrangement, in contrast, the pawl is protected inside the housing arranged and stored.

Nach vorteilhafter Ausgestaltung durchgreift die Sperrklinke mit einem Rastarm eine Öffnung im Gehäuse zur Wechselwirkung mit der Drehfalle. Der Rastarm an der Sperrklinke ist dabei so ausgelegt, dass er typischerweise in eine Vorrastaussparung oder Hauptrastaussparung der Drehfalle einfällt, sobald die Drehfalle die zugehörige Vorraststellung oder Hauptraststellung erreicht. Hierbei geht die Erfindung insgesamt von der Erkenntnis aus, dass diese rastende Wechselwirkung zwischen der Sperrklinke bzw. ihrem Rastarm und der Drehfalle nur geringfügige Bewegungen der Sperrklinke erfordert. Dementsprechend kann die von dem Rastarm der Sperrrklinke durchgriffene Öffnung im Gehäuse klein und schmal gehalten werden, trägt also den geringen Schwenkbewegungen der Sperrklinke im Betrieb Rechnung.According to an advantageous embodiment, the pawl engages with a latching arm an opening in the housing for interaction with the rotary latch. The locking arm on the pawl is designed so that it typically falls into a Vorrastaussparung or Hauptrastaussparung the catch as soon as the catch reaches the associated Vorraststellung or main latching position. In this case, the invention is based entirely on the knowledge that this latching Interaction between the pawl or its latching arm and the catch requires only minor movements of the pawl. Accordingly, the attacked by the locking arm of the pawl opening in the housing can be kept small and narrow, so takes into account the small pivoting movements of the pawl in operation.

Hierzu trägt ergänzend der Umstand bei, dass die Öffnung für den Rastarm als Öffnungsschlitz mit an eine Materialstärke der Sperrklinke angepasster Schlitzbreite ausgebildet ist. Die Schlitzlänge des Öffnungsschlitzes ist an den maximalen Stellweg der Sperrklinke bzw. des Rastarmes gegenüber der Öffnung angepasst.A further factor contributing to this is the fact that the opening for the latching arm is designed as an opening slot with a slot width adapted to a material thickness of the pawl. The slot length of the opening slot is adapted to the maximum travel of the pawl and the latching arm relative to the opening.

Im Allgemeinen ist der Sperrklinken-Lagerbolzen als Hohlbolzen ausgeführt und aus einem Kunststoff gefertigt.In general, the pawl bearing pin is designed as a hollow pin and made of a plastic.

Die Drehfalle ist im Allgemeinen endseitig eines Einlaufschlitzes für den Schließbolzen angeordnet. Zu diesem Zweck wird die Drehfalle meistens auf einem zugehörigen Drehfällen-Lagerbolzen gelagert. Dieser Drehfallen-Lagerbolzen wird vorteilhaft in einer Hohlbohrung des Gehäuses aufgenommen. Das heißt, die Hohlbohrung des Gehäuses fungiert als Lagerbuchse für den Drehfallen-Lagerbolzen, der typischerweise als Stahlstift, Stahlbolzen oder allgemein Metallbolzen ausgebildet ist. Zu seiner Anbringung ist es lediglich erforderlich, den fraglichen Drehfallen-Lagerbolzen in die Hohlbohrung im Gehäuse einzustecken und gegebenenfalls hieran zu fixieren bzw. adhäsiv.The rotary latch is disposed generally at the end of an inlet slot for the locking bolt. For this purpose, the catch is usually stored on an associated rotary bearing pin. This rotary latch bearing pin is advantageously received in a hollow bore of the housing. That is, the hollow bore of the housing acts as a bearing bush for the rotary latch bearing pin, which is typically designed as a steel pin, steel bolts or metal bolts in general. For its attachment, it is only necessary to insert the question in question rotary latch bearing pin in the hollow bore in the housing and optionally thereto to fix or adhesive.

Von seinem Grundaufbau her ist das Gehäuse im Allgemeinen mit einer Grundplatte und einem den Einlaufschlitz definierenden Vorsprung ausgerüstet. Das heißt, der Vorsprung kragt gegenüber der Grundplatte vor und definiert den bereits angesprochenen Einlaufschlitz. Dabei weist der Vorsprung unterseitig bzw. unterhalb die Hohlbohrungj zur Aufnahme des Drehfallen-Lagerbolzens auf. Die von dem Rastarm der Sperrklinke durchgriffenen Öffnung ist an bzw. unterhalb oder allgemein im Bereich des Vorsprunges vorgesehen. Meistens findet sich die Öffnung unterhalb einer Längskante des regelmäßig prismatisch und keilförmig ausgebildeten Vorsprunges. Hierbei handelt es sich um die sperrklinkenseitige Längskante des Vorsprunges.From its basic construction, the housing is generally equipped with a base plate and a projection defining the inlet slot. That is, the projection projects in front of the base plate and defines the already mentioned inlet slot. In this case, the projection on the lower side or below the Hohlbohrungj for receiving the rotary latch bearing pin. The attacked by the latching arm of the pawl opening is on or provided below or generally in the region of the projection. Most often, the opening is located below a longitudinal edge of the regularly prismatic and wedge-shaped projection. This is the pawl-side longitudinal edge of the projection.

Tatsächlich läuft der Vorsprung keilförmig in Richtung auf eine Querkante. Die gegenüberliegende Querkante des Vorsprunges ist offen gestaltet, so dass über diese Querkante der Schließbolzen in den Vorsprung einlaufen kann. Bei diesem Vorgang trifft der Schließbolzen auf die geöffnete Drehfalle und überführt diese zunächst in die Vorraststellung und dann die Hauptraststellung. Hierbei fällt der Rastarm an der Sperrklinke zunächst in die Vorrastaussparung und dann in die Hauptaussparung ein.In fact, the projection runs wedge-shaped in the direction of a transverse edge. The opposite transverse edge of the projection is designed to be open, so that over this transverse edge of the locking bolt can run into the projection. During this process, the locking bolt hits the opened catch and transfers it first to the pre-locking position and then to the main locking position. Here, the locking arm on the pawl first falls into the Vorrastaussparung and then into the main recess.

Der Vorsprung zur Definition des Einlaufschlitzes steht auf einer Drehfallen-Lagerfläche auf. Die Drehfallen-Lagerfläche ist gegenüber einer Sperrklinken-Lagerfläche um ein an die Materialstärke der Sperrklinke angepasstes Maß hochgezogen. Das heißt, die Sperrklinken-Lagerfläche definiert eine Grundfläche des Gehäuses. Gegenüber dieser Grundfläche bzw. der Sperrklinken-Lagerfläche ist die Drehfallen-Lagerfläche in Aufsicht hochgezogen oder eingezogen, so dass beim Übergang von der Sperrklinken-Lagerfläche zur Drehfallen-Lagerfläche eine Kante beobachtet wird. In dieser Kante findet sich der Öffnungsschlitz für den Rastarm der Sperrklinke. Außerdem ist die fragliche Kante im Bereich der sperrklinkenseitigen Längskante des Vorsprunges angeordnet.The projection for defining the inlet slot is on a rotary latch storage area. The rotary latch bearing surface is raised relative to a pawl bearing surface by a measure adapted to the material thickness of the pawl. That is, the pawl bearing surface defines a base of the housing. Compared with this base area or the pawl bearing surface, the rotary latch bearing surface is raised or retracted in plan view, so that an edge is observed during the transition from the pawl bearing surface to the rotary latch bearing surface. In this edge, there is the opening slot for the locking arm of the pawl. In addition, the edge in question is arranged in the region of the pawl-side longitudinal edge of the projection.

Neben dem bereits angesprochenen Gehäuse ist typischerweise auch eine das Gehäuse verschließende Gehäusehaube realisiert. In diesem Fall fungiert das im Wesentlichen das Gesperre und darüber hinaus noch weitere Hebel oder andere Elemente des Kraftfahrzeugtürschlosses aufnehmende Gehäuse als gleichsam Gehäuseunterteil. Demgegenüber übernimmt die Gehäusehaube praktisch die Funktion eines Gehäuseoberteiles. Auf diese Weise sind zur Halterung und Lagerung sämtlicher Elemente des erfindungsgemäßen Kraftfahrzeugtürschlosses letztlich nur zwei Strukturelemente erforderlich, nämlich das Gehäuse und die das Gehäuse verschließende Gehäusehaube. Prinzipiell ist es sogar denkbar, mit nur einem einzigen Strukturelement zu arbeiten. In jedem Fall verzichtet die Erfindung auf einen zusätzlichen Schlosskasten.In addition to the already mentioned housing, a housing cap closing the housing is typically also realized. In this case, the essentially the locking mechanism and, moreover, further levers or other elements of the motor vehicle door lock receiving housing acts as a housing lower part. In contrast, the housing cover takes over practically the function of a housing upper part. In this way are for mounting and Storage of all elements of the motor vehicle door lock according to the invention ultimately only two structural elements required, namely the housing and the housing cap closing the housing. In principle, it is even conceivable to work with only a single structural element. In any case, the invention dispenses with an additional lock case.

Dadurch wird insgesamt der konstruktive Aufwand verringert und können erhebliche Kosten eingespart werden. Hinzu kommt, dass das Gewicht des solchermaßen aufgebauten erfindungsgemäßen Kraftfahrzeugtürschlosses gegenüber bisherigen Ausführungsformen deutlich sinkt, was in Betracht der stetig steigenden Fahrzeuggewichte ausdrücklich erwünscht und besonders vorteilhaft ist. Außerdem lässt sich das erfindungsgemäße Kraftfahrzeugtürschloss bzw. das Gehäuse als wesentliches Strukturelement besonders einfach und umfassend herstellen, nämlich meistens im Zuge eines (einzigen) Kunststoffspritzgussverfahrens. Bei diesem Herstellungsvorgang werden weitere und bisher separat gefertigte Elemente zugleich mit realisiert, nämlich zumindest der Sperrklinken-Lagerbolzen. Meistens gehört hierzu auch die Lagerbuchse für den Drehfallen-Lagerbolzen, die im Zuge des beschriebenen Herstellungsvorganges ebenfalls mit definiert wird, und zwar als bereits im Detail beschriebene Hohlbohrung. Dadurch lassen sich wesentliche Kosteneinsparungen realisieren und sinkt auch das Gewicht des Kraftfahrzeugtürschlosses signifikant. Hierin sind die wesentliche Vorteile zu sehen.As a result, the overall design effort is reduced and significant costs can be saved. In addition, the weight of the thus constructed inventive motor vehicle door lock compared to previous embodiments drops significantly, which is expressly desirable and particularly advantageous in consideration of the ever-increasing vehicle weights. In addition, the motor vehicle door lock or the housing according to the invention as an essential structural element can be produced in a particularly simple and comprehensive manner, namely usually in the course of a (single) plastic injection molding process. In this manufacturing process further and previously separately manufactured elements are realized at the same time, namely at least the pawl bearing pin. Usually also includes the bearing bush for the rotary latch bearing pin, which is also defined in the course of the described manufacturing process, as well as already described in detail hollow bore. As a result, significant cost savings can be realized and the weight of the motor vehicle door lock also drops significantly. Here are the main benefits.

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

das erfindungsgemäße Kraftfahrzeugtürschloss mit eingebauter Sperrklinke und angedeuteter Drehfalle und
Fig. 2
den Gegenstand nach Fig. 1 mit abgenommener Sperrklinke.
In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:
Fig. 1
the motor vehicle door lock according to the invention with built-in pawl and indicated rotary latch and
Fig. 2
the object after Fig. 1 with removed pawl.

In den Figuren ist ein Kraftfahrzeugtürschloss dargestellt, welches über wenigstens ein Gehäuse 1 aus Kunststoff verfügt. Tatsächlich ist im Rahmen des Ausführungsbeispiels neben diesem Gehäuse 1 als wesentlichem Strukturelement bzw. einem auf diese Weise realisierten Gehäuseunterteil zusätzlich noch eine nicht dargestellte Gehäusehaube realisiert, die als Gehäuseoberteil fungiert. Diese Gehäusehaube kann mit dem Gehäuse 1 dichtend vereinigt werden und lässt sich hierzu beispielsweise in eine Nut 2 einstecken. Alternativ hierzu kann die Nut 2 aber auch eine Dichtung aufnehmen, die zwischen dem Gehäuse 1 und der nicht gezeigten Gehäusehaube einen verbleibenden Schlitz abdichtet.In the figures, a motor vehicle door lock is shown, which has at least one housing 1 made of plastic. In fact, in the context of the embodiment, in addition to this housing 1 as a substantial structural element or a housing base realized in this way, a housing cover, not shown, additionally realized, which acts as a housing upper part. This housing cover can be sealingly combined with the housing 1 and can be, for example, plug into a groove 2. Alternatively, the groove 2 but also receive a seal that seals a remaining slot between the housing 1 and the housing cover, not shown.

Zum grundsätzlichen Aufbau des gezeigten Kraftfahrzeugtürschlosses gehört neben dem wenigstens einen Gehäuse 1 aus Kunststoff ergänzend noch ein Gesperre 3, 4, welches sich im Wesentlichen aus einer Drehfalle 3 und einer Sperrklinke 4 zusammensetzt. Von erfindungswesentlicher Bedeutung ist nun der Umstand, dass die Sperrklinke 4 im Innern des Gehäuses 1 gelagert ist, wohingegen die Drehfalle 3 eine Lagerung außerhalb am Gehäuse 1 erfährt. Im Detail ist die Drehfalle 3 auf einem Drehfallen-Lagerbolzen 5 gelagert. Die Sperrklinke erfährt eine Lagerung auf einem Sperrklinken-Lagerbolzen 6, der vorliegend als Hohlbolzen 6 ausgebildet ist.For the basic structure of the motor vehicle door lock shown in addition to the at least one housing 1 made of plastic additionally includes a locking mechanism 3, 4, which essentially consists of a rotary latch 3 and a pawl 4. Essential to the invention is now the fact that the pawl 4 is mounted in the interior of the housing 1, whereas the catch 3 experiences a bearing outside the housing 1. In detail, the rotary latch 3 is mounted on a rotary latch bearing pin 5. The pawl experiences a bearing on a pawl-bearing pin 6, which is formed here as a hollow pin 6.

Der Sperrklinken-Lagerbolzen 6 ist einstückig an das Gehäuse 1 angeformt. Tatsächlich werden der Sperrklinken-Lagerbolzen 6 und das Gehäuse 1 in einem gemeinsamen Vorgang, beispielsweise einem gemeinsamen Kunststoffspritzgussverfahren, hergestellt. Aus Gründen der Stabilität kann der Sperrklinken-Lagerbolzen 6 über eine in das Kunststoffmaterial eingebettete Verstärkung verfügen. Das ist im Detail jedoch nicht dargestellt.The pawl bearing pin 6 is integrally formed on the housing 1. In fact, the pawl bearing pin 6 and the housing 1 are manufactured in a common operation, for example a common plastic injection molding process. For reasons of stability, the pawl bearing pin 6 may have a reinforcement embedded in the plastic material. This is not shown in detail.

Die Sperrklinke 4 verfügt über einen Rastarm 4a, welcher eine Öffnung 7 im Gehäuse 1 zur Wechselwirkung mit der Drehfalle 3 durchgreift. Man erkennt in den Figuren, dass die Öffnung 7 als Öffnungsschlitz 7 ausgebildet ist.The pawl 4 has a latching arm 4 a, which passes through an opening 7 in the housing 1 for interaction with the rotary latch 3. It can be seen in the figures that the opening 7 is formed as an opening slot 7.

Der Öffnungsschlitz 7 verfügt über eine Schlitzbreite, welche an eine Materialstärke b der Sperrklinke 4 angepasst ist. Eine Schlitzlänge I der Öffnung bzw. des Öffnungsschlitzes 7 trägt den maximalen Schwenkbewegungen des Rastarmes 4a der Sperrklinke 4 beim bestimmungsgemäßen Gebrauch Rechnung. Tatsächlich wird die Sperrklinke 4 beim Schließvorgang des Gesperres 3, 4 dazu eingesetzt, zunächst in eine nicht näher dargestellte Vorrastaussparung und dann eine Hauptrastaussparung der Drehfalle 3 einfallen zu können, um die Drehfalle 3 in der zugehörigen Vorraststellung bzw. Hauptraststellung zu halten. Dadurch wird auch der diesen Vorgang initiierende und nicht ausdrücklich dargestellte Schließbolzen von dem Gesperre 3, 4 gefangen. Umgekehrt muss die Sperrklinke 4 von der Drehfalle 3 abgehoben werden, damit die Drehfalle 3 federunterstützt öffnen kann und den Schließbolzen freigibt.The opening slot 7 has a slot width, which is adapted to a material thickness b of the pawl 4. A slot length I of the opening or of the opening slot 7 carries the maximum pivoting movements of the latching arm 4 a of the pawl 4 when used as intended. In fact, the pawl 4 is used during the closing process of the locking mechanism 3, 4 to first come into a Vorrastaussparung not shown and then a Haupttrastaussparung the catch 3 to hold the catch 3 in the associated pre-locking position or main detent position. As a result, the locking pin initiating this process and not expressly shown is caught by the locking mechanism 3, 4. Conversely, the pawl 4 must be lifted from the catch 3, so that the catch 3 can open spring-assisted and releases the locking pin.

Man erkennt, dass die Drehfalle 3 endseitig eines Einlaufschlitzes 8 angeordnet ist. Zu diesem Zweck wird der Drehfallen-Lagerbolzen 5 in einer Hohlbohrung 9 des Gehäuses 1 aufgenommen. Diese Hohlbohrung 9 findet sich unterhalb eines Vorsprunges 10. Der Vorsprung 10 ist ferner mit einem Zapfen 11 zur Aufnahme weiterer und nicht dargestellter Schlosselemente ausgerüstet.It can be seen that the rotary latch 3 is arranged at the end of an inlet slot 8. For this purpose, the rotary latch bearing pin 5 is received in a hollow bore 9 of the housing 1. This hollow bore 9 is located below a projection 10. The projection 10 is further equipped with a pin 11 for receiving further and not shown lock elements.

Im Detail weist das Gehäuse 1 zunächst einmal eine Grundplatte 12 auf, die im gezeigten Beispielfall zugleich als Sperrklinken-Lagerfläche 12 bzw. Grundfläche fungiert. Neben dieser Grundplatte 12 respektive der hierdurch aufgespannten Grundfläche bzw. der hierdurch geschaffenen Sperrklinken-Lagerfläche 12 ist das Gehäuse 1 zusätzlich noch mit einer Drehfallen-Lagerfläche 13 ausgerüstet. Die Drehfallen-Lagerfläche 13 ist gegenüber der Sperrklinken-Lagerfläche 12 um ein an die Materialstärke b der Sperrklinke 4 angepasstes Maß eingezogen bzw. in Aufsicht hochgezogen. Das heißt, beim Übergang von der Sperrklinken-Lagerfläche 12 zur Drehfallen-Lagerfläche 13 beobachtet man einen Vorsprung bzw. einen Absatz 14, der eine der Materialstärke b der Sperrklinke 4 entsprechende Höhe aufweist. In diesem Absatz 14 ist die Öffnung bzw. der Öffnungsschlitz 7 ausgebildet.In detail, the housing 1 initially has a base plate 12, which also acts as a pawl bearing surface 12 or base in the example shown. In addition to this base plate 12, respectively the base area spanned thereby or the pawl bearing surface 12 created thereby, the housing 1 is additionally equipped with a rotary latch bearing surface 13. The rotary latch bearing surface 13 is retracted relative to the pawl bearing surface 12 by a measure adapted to the material thickness b of the pawl 4 measure or pulled up in supervision. That is, in the transition from the pawl bearing surface 12 to the rotary latch bearing surface 13 is observed a projection or a shoulder 14, the one of the material thickness b of the pawl 4th corresponding height. In this paragraph 14, the opening or the opening slot 7 is formed.

Der Vorsprung 10 steht nun auf der Drehfallen-Lagerfläche 13 auf, die ihrerseits gegenüber der Sperrklinken-Lagerfläche 12 wie beschrieben hochgezogen oder eingezogen ist.The projection 10 now stands on the rotary latch bearing surface 13, which in turn is pulled up or retracted relative to the pawl bearing surface 12 as described.

Der Vorsprung 10 verfügt insgesamt über eine prismatische Gestalt. Tatsächlich läuft der Vorsprung 10 keilförmig in Richtung auf die Drehfalle 3 bzw. eine dortige Querkante zu. Tatsächlich weist der Vorsprung 10 unterseitig bzw. unterhalb die Hohlbohrung 9 zur Aufnahme des Drehfallen-Lagerbolzens 5 auf. Die betreffende Hohlbohrung 9 findet sich folglich an der unteren Längskante des im Querschnitt trapezartig ausgebildeten Vorsprunges 10. Im Bereich der oberen sperrklinkenseitigen Längskante des Vorsprungs 10 ist die Öffnung 7 für den Sperrklinkenarm 4a vorgesehen.The projection 10 has a total of a prismatic shape. In fact, the projection 10 runs wedge-shaped in the direction of the rotary latch 3 or a transverse edge there. In fact, the projection 10 on the underside and below the hollow bore 9 for receiving the rotary latch bearing pin 5. The respective hollow bore 9 is therefore located at the lower longitudinal edge of the trapezoidal cross-section in the projection 10. In the region of the upper pawl-side longitudinal edge of the projection 10, the opening 7 is provided for the pawl 4 a.

Die einlaufseitige Querkante des Vorsprunges 11 ist offen gestaltet, so dass hierüber der Schließbolzen in den Einlaufschlitz 8 einfahren kann. Die beiden Längskanten des Vorsprunges 10 laufen keilförmig zu, um den Schließbolzen in Richtung auf die Drehfalle 3 zu führen.The inlet-side transverse edge of the projection 11 is designed to be open, so that over this the locking pin can enter into the inlet slot 8. The two longitudinal edges of the projection 10 run in a wedge shape to guide the locking pin in the direction of the rotary latch 3.
