Description

Schloss mit Blockαdehebel nebst austariertem Schwerpunkt Lock with blockage lever and balanced center of gravity
Die Erfindung betrifft ein Schloss für ein Kraftfahrzeug mit einem Gesperre umfassend eine Drehfalle und eine Sperrklinke, mit der die Drehfalle in einer Schließstellung verriegelt werden kann . Das Gesperre weist ferner einen Blockadehebel auf, mit dem die Sperrklinke blockiert wird, wenn diese die Drehfalle verriegelt. Die Erfindung betrifft insbesondere ein Schloss mit einer Sperrklinke für die Hauptrast (nachfolgend „Hauptrast-Sperrklinke" genannt), einer Sperrklinke für die Vorrast (nachfolgend „Vorrast-Sperrklinke" genannt) und einem Blockadehebel für die genannte Hauptrast - Sperrklinke. Eine solches Schloss ist aus der Druckschrift DE 1 0 2007 003 948 Al bekannt.The invention relates to a lock for a motor vehicle with a locking mechanism comprising a rotary latch and a pawl, with which the rotary latch can be locked in a closed position. The ratchet also has a blocking lever which locks the pawl when it locks the ratchet. More particularly, the invention relates to a lock having a main ratchet pawl (hereinafter called "main ratchet pawl"), a ratchet pawl (hereinafter called "pre-ratchet pawl") and a blocking lever for said main ratchet pawl. Such a lock is known from the publication DE 1 0 2007 003 948 Al.
Eine Drehfalle eines Kraftfahrzeugschlosses verfügt über einen gabelförmigen Einlaufschlitz, in den ein Schließbolzen einer Fahrzeugtür oder einer Fahrzeugklappe gelangt, wenn die Fahrzeugtür oderA rotary latch of a motor vehicle lock has a fork-shaped inlet slot into which a locking bolt of a vehicle door or a vehicle door, when the vehicle door or
Fahrzeugklappe geschlossen wird . Der Schließbolzen verdreht dann die Drehfalle von einer geöffneten Stellung - auch Öffnungsstellung genannt - in eine Schließstellung . Hat die Drehfalle eine Schließstellung erreicht, so kann der Schließbolzen den Einlaufschlitz der Drehfalle nicht mehr verlassen . In der Schließstellung verriegelt eine Sperrklinke die Drehfalle, so dass diese nicht mehr in die Öffnungsstellung zurückgedreht werden kann.Vehicle flap is closed. The locking pin then rotates the catch from an open position - also called open position - in a closed position. If the catch has reached a closed position, then the locking pin can not leave the inlet slot of the catch. In the closed position, a pawl locks the catch, so that it can not be rotated back into the open position.
Regelmäßig gibt es bei einem Schloss für ein Kraftfahrzeug aus Sicherheitsgründen zwei Schließstellungen, die nacheinander während des Schließens von der Drehfalle eingenommen werden können, nämlich die sogenannte Vorrast und die sogenannte Hauptrast.For safety reasons, there are regularly two closed positions in a lock for a motor vehicle, which can be taken in succession during closing by the rotary latch, namely the so-called pre-rest and the so-called main lock.
Um zu vermeiden, dass eine Sperrklinke nicht unplanmäßig aus ihrer verriegelnden Stellung heraus bewegt wird, kann ein Blockadehebel vorgesehen sein, der eine solche Bewegung blockiert, wenn die Drehfalle verriegelt ist. Ein solcher hakenförmiger Blockadehebel ist bei dem aus der Druckschrift DE 1 0 2007 003 948 Al bekannten Schloss für die Hauptrast- Sperrklinke erforderlich, da die Drehfalle und die Hauptrast-Sperrklinke so konstruiert sind, dass die Sperrklinke in der Hauptrast die Hauptrast- Sperrklinke aus der verriegelnden Stellung drängt.In order to avoid that a pawl is not moved unintentionally out of its locking position, a blocking lever may be provided which blocks such movement when the catch is locked. Such a hook-shaped blocking lever is required in the known from the document DE 1 0 2007 003 948 Al lock for the main catch pawl, as the catch and the main catch pawl so are designed so that the pawl in the main catch urges the Hauptastast- pawl from the locking position.
Der aus der Druckschrift DE 1 0 2007 003 948 Al bekannte, drehbar gelagerte Blockadehebel ist durch eine Feder vorgespannt. Aufgrund dieser Vorspannung übt der Blockadehebel einen Druck auf die Hauptrast - Sperrklinke in Richtung Drehfalle aus, wenn sich die Drehfalle nicht in der Hauptrast-Stellung befindet. Dieser Druck ist dafür verantwortlich, dass die Hauptrast-Sperrklinke in ihre verriegelnde Stellung hinein bewegt wird, wenn die Drehfalle die Hauptrast erreicht. Die Vorspannung trägt dann weiter dafür Sorge, dass der Blockadehebel abschließend in die blockierende Stellung bewegt wird, so dass die Fahrzeugtür oder Fahrzeugklappe so vollständig verschlossen wird .The known from the document DE 1 0 2007 003 948 Al, rotatably mounted blocking lever is biased by a spring. Due to this bias, the blocking lever exerts pressure on the main catch pawl towards the catch when the catch is not in the main catch position. This pressure is responsible for moving the main latch pawl into its latching position when the latch reaches the main latch. The bias then continues to ensure that the blockage lever is finally moved to the blocking position, so that the vehicle door or vehicle door is so completely closed.
Um das Schloss zu entriegeln, wird der Blockadehebel mithilfe der Vorrast - Sperrklinke entgegengesetzt zu seiner Vorspannung gedreht, bis der Blockadehebel die Hauptrast - Sperrklinke freigibt. Die Hauptrast - Sperrklinke wird dann durch die Drehfalle aus der verriegelnden Stellung gedrängt oder durch einen Mitnehmer der Vorrast-Sperrklinke erfasst und so aus der verriegelnden Stellung heraus bewegt. Im Anschluss daran dreht sich dieTo unlock the lock, the blockage lever is rotated counter to its bias by means of the pre - ratchet pawl until the blockage lever releases the main catch pawl. The main catch pawl is then urged by the catch from the locking position or detected by a catch of the pre-locking pawl and so moved out of the locking position. After that, the film turns

Der Schließbolzen kann nun wieder aus dem Einlaufschlitz heraus bewegt und die entsprechende Fahrzeugtür oder Fahrzeugklappe geöffnet werden .Rotary latch due to a corresponding bias of the main load in its open position. The locking bolt can now be moved out of the inlet slot again and the corresponding vehicle door or vehicle door can be opened.
Die aus der Druckschrift DE 1 0 2007 003 948 Al bekannte Vorrast-Sperrklinke ist durch eine Feder in Richtung Drehfalle vorgespannt. Diese Vorspannung trägt dafür Sorge, dass die Vorrast-Sperrklinke in ihre verriegelnde Stellung gelangt, wenn durch entsprechendes Drehen der Drehfalle die dafür erforderliche Stellung erreicht wird . Es ist Aufgabe der Erfindung, ein gut funktionierendes Schloss für ein Kraftfahrzeug bereitzustellen .The Vorrast pawl known from the document DE 1 0 2007 003 948 Al is biased by a spring in the direction of the rotary latch. This bias ensures that the pre-locking pawl gets into its locking position when the required position is achieved by appropriate rotation of the rotary latch. It is an object of the invention to provide a well-functioning lock for a motor vehicle.
Die Aufgabe der Erfindung wird durch ein Schloss mit den Merkmalen des ersten Anspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen .The object of the invention is achieved by a lock with the features of the first claim. Advantageous embodiments emerge from the subclaims.
Das anspruchsgemäße Schloss für ein Kraftfahrzeug ist mit einem Gesperre aus einer Drehfalle und wenigstens einer Sperrklinke, insbesondere einer Vorrast-Sperrklinke für ein erstes Verriegeln der Drehfalle und einer Hauptrast- Sperrklinke für ein nachfolgendes Verriegeln der Drehfalle versehen. Das Schloss weist außerdem einen Blockadehebel auf, der die wenigstens eine Sperrklinke blockiert, wenn diese die Drehfalle verriegelt. Die Sperrklinke kann aus der verriegelnden Stellung nicht heraus bewegt werden, wenn diese durch den Blockadehebel blockiert ist.The claimed castle for a motor vehicle is provided with a locking mechanism of a catch and at least one pawl, in particular a pre-locking pawl for a first locking the catch and a Haupttrast- pawl for subsequent locking of the catch. The lock also includes a blocking lever which blocks the at least one pawl when it locks the catch. The pawl can not be moved out of the locking position when it is blocked by the blocking lever.
Im Unterschied zum eingangs genannten Stand der Technik weist der drehbar gelagerte Blockadehebel wenigstens zwei Hebelarme auf, die sich von der Drehachse aus gesehen im Wesentlichen in entgegengesetzte Richtungen erstrecken . Dadurch wird im Vergleich zum eingangs genannten hakenförmigen Blockadehebel der Schwerpunkt hin zur Drehachse verlegt. Dies erleichtert das Drehen des Blockadehebels. Im Vergleich zu einem hakenförmigen Blockadehebel funktioniert das Schloss entsprechend verbessert.In contrast to the prior art mentioned at the beginning, the rotatably mounted blocking lever has at least two lever arms which, viewed from the axis of rotation, extend substantially in opposite directions. As a result, the center of gravity is moved towards the axis of rotation compared to the aforementioned hook-shaped blockage lever. This facilitates the rotation of the blockage lever. Compared to a hook-shaped blockage lever, the lock works accordingly improved.
In einer Ausführungsform der Erfindung wirkt auf einen der beiden Hebelarme eine Feder ein, die den Blockadehebel in Richtung blockierende Stellung drückt, um den Blockadehebel in diese Stellung hinein zu bewegen, wenn die entsprechende Sperrklinke die Drehfalle verriegelt. Bevorzugt ist dieser Hebelarm relativ lang, also etwas länger als der andere entgegengesetzte Hebelarm, damit die auf diesen Hebelarm wirkende Federkraft besonders leicht die gewünschte Drehbewegung des Blockαdehebels zu bewirken vermag .In one embodiment of the invention acts on one of the two lever arms, a spring which presses the blocking lever in the blocking position to move the blocking lever into this position, when the corresponding pawl locks the rotary latch. Preferably, this lever arm is relatively long, so slightly longer than the other opposite lever arm, so that the force acting on this lever spring force especially can easily cause the desired rotational movement of the Blockαdehebels.
In einer Ausführungsform der Erfindung gibt es einen Anschlag für einen der beiden Hebelarme und zwar vorzugsweise für den Hebelarm, auf den keine Feder einwirkt. Der Anschlag wird durch den Hebelarm erreicht, wenn der Blockadehebel in seine blockierende Stellung gelangt. Hierdurch wird einerseits sichergestellt, dass der Blockadehebel stets sehr präzise seine blockierende Endstellung erreicht, was für ein gutes Funktionieren des Schlosses sehr wichtig ist, da die zulässigen Toleranzen in dieser Hinsicht besonders gering sind . Ist der eine Hebelarm federbelastet und kann der andere Hebelarm gegen den genannten Anschlag bewegt werden, so haben beide Hebelarme eine weitergehende technische Funktion . Aus im Zusammenhang mit dem Ausführungsbeispiel genannten Gründen ist es vorteilhaft, den nicht federbelasteten Hebelarm für das Erreichen eines Anschlags zu verwenden . Die Vorspannung, die auf den federbelasteten Hebelarm wirkt, kann dann nämlich in der im Ausführungsbeispiel erläuterten Weise vorteilhaft mit Hilfe einer weiteren Sperrklinke gesteuert werden .In one embodiment of the invention, there is a stop for one of the two lever arms, and preferably for the lever arm, which is acted upon by no spring. The stop is reached by the lever arm when the blocking lever reaches its blocking position. This ensures on the one hand that the blocking lever always reaches its blocking end position very precisely, which is very important for a good functioning of the lock, since the permissible tolerances are particularly low in this regard. If one lever arm is spring-loaded and if the other lever arm can be moved against the abovementioned stop, then both lever arms have a further technical function. For reasons mentioned in connection with the exemplary embodiment, it is advantageous to use the non-spring-loaded lever arm for reaching a stop. The bias, which acts on the spring-loaded lever arm can then be advantageously controlled in the manner explained in the embodiment advantageously with the aid of a further pawl.

Nachfolgend wird ein in den Figuren 1 bis 4 gezeigtes Ausführungsbeispiel der Erfindung näher erläutert. Anhand des Ausführungsbeispiels werden Vorteile von weiteren Ausführungsformen der Erfindung verdeutlicht.Hereinafter, an embodiment of the invention shown in Figures 1 to 4 will be explained in more detail. On the basis of the embodiment advantages of further embodiments of the invention are illustrated.
In der Figur 1 ist eine Aufsicht auf eine Gehäusewand 1 eines Fahrzeugschlosses dargestellt. Die Gehäusewand 1 ist mit einem Einlaufschlitz 2 versehen, in den ein Schließbolzen 3 einer Fahrzeugtür oder einer Fahrzeugklappe hinein gelangt, wenn die zugehörige Fahrzeugtür oder Fahrzeugklappe geschlossen wird . Die Drehfalle 4 ist auf der Gehäusewand 1 drehbar angebracht und kann um ihre Befestigungsachse 5 gedreht werden . In der Figur 1 wird die Hauptrast gezeigt, bei der der im Gehäusewand-Einlaufschlitz 2 befindliche Schließbolzen 3 von dem Einlaufschlitz der Drehfalle so umschlossen wird, dass der Schließbolzen 3 nicht mehr aus dem Gehäusewand-Einlaufschlitz 2 heraus bewegt werden kann . Die entsprechende Tür beziehungsweise die Klappe des Fahrzeugs ist damit verschlossen . Gezeigt wird die Hauptrast, weil ein Zurückdrehen der Drehfalle gemäß gezeigter Pfeilrichtung 22 in die geöffnete Stellung durch die Hauptrast - Sperrklinke 6 wie dargestellt verhindert wird . Die Hauptrast - Sperrklinke 6 ist ebenfalls auf der Gehäusewand 1 befestigt und kann um ihre Befestigungsachse 7 gedreht werden. Die Drehfalle 4 kann durch eine nicht gezeigte Feder in Richtung geöffnete Stellung vorgespannt sein. Aufgrund einer solchen Vorspannung drückt die Drehfalle 4 gegen einen Anschlag der Hauptrast - Sperrklinke mit einem schrägen Verlauf . Dieser schräge Verlauf drängt die Hauptrast - Sperrklinke aus der verriegelnden Stellung heraus. Ist die Drehfαlle nicht durch eine Feder vorgespannt, so bewirkt zumindest der Schließbolzen 3 eine Drehbewegung der Drehfalle 4 in Richtung geöffnete Stellung gemäß Pfeil 22, wenn eine zugehörige Fahrzeugtür oder Fahrzeugklappe geöffnet wird . Das damit einhergehende Drehmoment drängt dann die Hauptrast-Sperrklinke 6 aus der verriegelnden Stellung heraus.FIG. 1 shows a plan view of a housing wall 1 of a vehicle lock. The housing wall 1 is provided with an inlet slot 2 into which a locking bolt 3 of a vehicle door or a vehicle door enters when the associated vehicle door or vehicle door is closed. The rotary latch 4 is rotatably mounted on the housing wall 1 and can be rotated about its mounting axis 5. In the figure 1, the main load is shown, in which the locking bolt 3 located in the housing wall inlet slot 2 is so enclosed by the inlet slot of the rotary latch that the locking pin 3 can not be moved out of the housing wall inlet slot 2. The corresponding door or the flap of the vehicle is thus closed. Shown is the main catch, because a turning back of the catch according to arrow direction shown 22 is prevented in the open position by the main catch - pawl 6 as shown. The main catch - pawl 6 is also mounted on the housing wall 1 and can be rotated about its mounting axis 7. The rotary latch 4 may be biased by a spring, not shown, in the open position. Due to such a bias, the rotary latch 4 presses against a stop of the main catch - pawl with an oblique course. This oblique course urges the main catch pawl out of the locking position. If the Drehfαlle is not biased by a spring, so causes at least the locking pin 3 is a rotational movement of the rotary latch 4 in the open position shown in arrow 22 when an associated vehicle door or vehicle door is opened. The associated torque then urges the main catch pawl 6 out of the locking position.
Dies wird allerdings in der Hauptrast bei verschlossener Fahrzeugtür oder Fahrzeugklappe durch einen Blockadehebel 8 wie gezeigt verhindert. Der Blockadehebel 8 ist ebenfalls auf der Gehäusewand 1 befestigt und kann um seine Befestigungsachse 9 gedreht werden . An einem seitlichen Konturbereich des Blockadehebels 8 liegt ein Arm 1 0b einer Feder 1 0 an. Die Feder 1 0 ist so vorgespannt, dass der Arm 1 Ob der Feder 1 0 den Blockadehebel 8 in Richtung der gezeigten Blockadestellung (in Richtung Pfeil 1 1 ) drängt. Begrenzt wird die dadurch verursachte Drehbewegung des Blockadehebels 8 wie gezeigt durch einen Anschlag 1 2, der in Form eines vorstehenden Bolzens an der Gehäusewand 1 befestigt ist. Die Feder 1 0 ist überwiegend seitlich neben dem Blockadehebel 8 sowie neben einer Vorrastsperrklinke angeordnet, um eine geringe Bauhöhe zu ermöglichen . Lediglich ein Arm 1 0a der Feder 1 0 reicht über den Blockadehebel 8 hinweg .However, this is prevented in the main load when the vehicle door or vehicle door is locked by a blocking lever 8 as shown. The blocking lever 8 is also mounted on the housing wall 1 and can be rotated about its mounting axis 9. At a lateral contour region of the blocking lever 8 is an arm 1 0b of a spring 1 0 at. The spring 1 0 is biased so that the arm 1 Whether the spring 1 0 the blocking lever 8 in the direction of the blockage position shown (in the direction of arrow 1 1) urges. The rotational movement of the blocking lever 8 caused thereby is limited as shown by a stop 1 2 which is fastened to the housing wall 1 in the form of a protruding bolt. The spring 10 is mainly arranged laterally next to the blocking lever 8 and next to a Vorrastsperrklinke to allow a low height. Only one arm 1 0a of the spring 1 0 extends beyond the blocking lever 8 away.
Oberhalb der Hauptrast - Sperrklinke 6 ist eine Vorrast - Sperrklinke angeordnet. Diese ist ebenfalls an der Achse 7 drehbar befestigt und kann also um diese Achse 7 gedreht werden. Der Umriss 1 3 der Vorrast -Above the main catch pawl 6, a pre-locking pawl is arranged. This is also rotatably mounted on the axis 7 and can therefore be rotated about this axis 7. The outline 1 3 of the pre-rest
Sperrklinke ist punktiert angedeutet. Die Vorrast - Sperrklinke 1 3 umfasst einen Bolzen 1 4, der sich von der Vorrast - Sperrklinke in Richtung Gehäusewand 1 erstreckt. An diesem Bolzen 1 4 liegt der andere Arm 1 0a der Feder 1 0 an . Der andere Arm 1 0a der Feder 1 0 drückt in Richtung des Bolzens 1 4 entlang des Pfeils 1 5. In der Hauptrast liegt der Bolzen 1 4 außerdem an einem seitlichen Konturbereich des Blockadehebels 8 an, um Öffnungsgeräusche zu vermeiden . Wird die Vorrast - Sperrklinke 1 3 in Richtung des Pfeils 1 6 gedreht, so bewirkt der Bolzen 1 4, dass der Blockadehebel 8 aus der blockierenden Stellung heraus gedreht wird . Zugleich wird aufgrund der Drehbewegung der Vorrast - Sperrklinke 1 3 der Federarm 1 0a mit bewegt. Dies erleichtert das Drehen des Blockadehebels 8 durch die Sperrklinke 1 3 für die Vorrast aus der blockierenden Stellung heraus, weil kein Gegendruck des Federarms 1 0b zu überwinden ist. Wird der Blockadehebel 8 so aus der blockierenden Stellung heraus bewegt, so wird die Hauptrast-Sperrklinke 6 aus ihrer gezeigten verriegelnden Stellung durch die Drehfalle heraus gedrängt. Ergänzend oder alternativ erfasst ein seitlicher Konturbereich der Vorrast-Sperrklinke 1 3 infolge der genannten Drehbewegung einen vorstehenden als Anschlag dienenden Bolzen 1 7, der auf der Hauptrast-Sperrklinke 6 befestigt ist. Dies hat zur Konsequenz, dass die Hauptrast-Sperrklinke 6 aus der gezeigten verriegelnden Stellung heraus gedreht wird und die Drehfalle freigibt. Diese schwenkt dann in Richtung des Pfeils 22 in Richtung geöffnete Stellung und gibt schließlich den Schließbolzen 3 frei . Die zugehörige Tür oder Klappe kann dann geöffnet werden .Pawl is indicated dotted. The pre-locking pawl 1 3 comprises a bolt 1 4, which extends from the pre-locking pawl in the direction of the housing wall 1. At this bolt 1 4 is the other arm 1 0a of the spring 1 0 at. The other arm 1 0a of the spring 1 0 presses in the direction of the bolt 1 4 along the arrow 1 5. In the main load of the bolt 1 4 also bears on a lateral contour portion of the blocking lever 8 to avoid opening noise. If the pre-locking pawl 1 3 is rotated in the direction of arrow 1 6, the pin 1 4 causes the blocking lever 8 is rotated out of the blocking position. At the same time the spring arm 1 0a is due to the rotational movement of the pre-locking pawl 1 3 moves with. This facilitates the rotation of the blocking lever 8 by the pawl 1 3 for the pre-locking out of the blocking position, because no back pressure of the spring arm 1 0b is overcome. If the blocking lever 8 is thus moved out of the blocking position, the main-locking pawl 6 is urged out of its shown locking position by the rotary latch. Additionally or alternatively detects a lateral contour portion of the pre-locking pawl 1 3 as a result of said rotational movement a protruding serving as a stop pin 1 7, which is mounted on the main catch pawl 6. This has the consequence that the main locking pawl 6 is rotated out of the illustrated locking position and releases the catch. This then pivots in the direction of the arrow 22 in the direction of the open position and finally releases the locking pin 3. The associated door or flap can then be opened.
Die Vorrast-Sperrklinke 1 3 kann die Drehfalle 4 ebenfalls verriegeln, wenn ein vorstehender Bolzen 1 8 der Drehfalle 2 auf den seitlichen Konturbereich 1 9 der Vorrast-Sperrklinke 1 3 auftrifft und so ein Drehen der Sperrklinke in Richtung geöffnete Stellung gemäß Pfeil 22 verhindert. Die Vorrast- Sperrklinke 1 3 ist durch eine nicht gezeigte Feder in Richtung Drehfalle und damit in Richtung ihrer verriegelnde Stellung vorgespannt. Ein als Anschlag dienender vorstehender Bolzen 20, der auf der Gehäusewand 1 befestigt ist, verhindert das weitere Drehen der Vorrast-Sperrklinke über ihre verriegelnde Stellung hinaus.The pre-locking pawl 1 3 can also lock the catch 4 when a protruding pin 1 8 of the catch 2 impinges on the lateral contour portion 1 9 of the pre-locking pawl 1 3 and thus prevents rotation of the pawl in the direction of open arrow 22. The pre-locking pawl 1 3 is biased by a spring not shown in the direction of the catch and thus in the direction of its locking position. A protruding pin 20 serving as a stopper mounted on the housing wall 1 prevents further rotation of the pre-locking pawl beyond its locking position.
Die Hauptrast-Sperrklinke 6 ist bevorzugt nicht federbelastet. Die Hauptrast- Sperrklinke 6 wird dann statt dessen allein durch Bewegen der Drehfalle 4, der Vorrast - Sperrklinke 1 3 und dem Blockadehebel 8 geeignet gedreht, so zum Beispiel durch eine Drehbewegung des Blockadehebels 8 in die verriegelnde Stellung (Hauptrast) hinein . Das entsprechende Drehen des Blockadehebels wird durch die gesteuert bereitgestellte Vorspannung der Feder 1 0 bewirkt. Diese Vorspannung wird allerdings durch entsprechendes Bewegen der Vorrast- Sperrklinke gesteuert und so bereitgestellt. Verliert die Feder, mit der die Vorrαst-Sperrklinke in Richtung ihrer verriegelnden Stellung gedrückt wird, ihre Wirkung, so entfällt damit auch die Vorspannung, die den Blockadehebel in Richtung blockierende Stellung und damit zugleich die Hauptrast-Sperrklinke in Richtung verriegelnde Stellung hin zur Drehfalle drückt. Wird eine zugehörige Fahrzeugtür oder Fahrzeugklappe verschlossen, so kann die Hauptrast-Sperrklinke nicht mehr in die verriegelnde Stellung einrasten und die entsprechende Tür oder Klappe nicht mehr verschlossen werdenThe main catch pawl 6 is preferably not spring loaded. The main catch pawl 6 is then instead rotated solely by moving the catch 4, the pre-locking pawl 1 3 and the blocking lever 8, so for example by a rotational movement of the blocking lever 8 in the locking position (main catch) into it. The corresponding rotation of the blocking lever is effected by the control provided bias of the spring 1 0. However, this bias is controlled by appropriately moving the pre-locking pawl and thus provided. Loses that Spring, with the Vorrαst pawl is pressed in the direction of its locking position, their effect, so eliminating the bias that pushes the blocking lever in the blocking position and thus at the same time the main locking pawl towards locking position towards the catch. If an associated vehicle door or vehicle door is closed, the main-locking pawl can no longer engage in the locking position and the corresponding door or flap can not be closed
Um die Hauptrast-Sperrklinke mit Hilfe des Blockadehebels geeignet in die verriegelnde Stellung hinein zu bewegen, haben sich hakenförmige Endungen 6b und 8a als besonders geeignet herausgestellt. Der Kopf des Hakens 6b der Hauptrast-Klinke wirkt als Anschlag für die Drehfalle. Die Hakenspitze des Hakens 6b wird durch den Kopf des Hakens 8a in der Hauptrast blockiert. Wird der Blockadehebel 8 aus der blockierenden Stellung heraus gedreht, so verhaken sich die beiden Haken 6b und 8a ineinander. Insgesamt kann so besonders zuverlässig der gewünschte Bewegungsablauf gewährleistet werden . Die Haken bewirken außerdem, dass der Hebelarm 8b des Blockadehebels, auf den die Feder 1 0 einwirkt, durch den Haken 6b besonders weit nach außen gedrückt wird, wenn die Drehfalle in die geöffnete Stellung bewegt wird . Dieser Hebelarm des Blockadehebels liegt dann nicht mehr an dem Bolzen 1 4 an, wodurch die Vorspannung vergrößert wird, die dann in der geöffneten Stellung der Drehfalle den Blockadehebel in Richtung blockierende Stellung drückt. Diese Erhöhung der Vorspannung durch die Feder 1 0 (indem sich der entsprechende Hebelarm 8b von dem Bolzen 1 4 entfernt), wird nicht durch Drehen der Vorrast-Sperrklinke 1 3 bewirkt, sondern durch Drehen der Hauptrast-Sperrklinke 6 in Richtung des Pfeils 1 6 aus ihrer verriegelnden Stellung heraus. Diese Drehung der Hauptrast-Sperrklinke wird wiederum durch Drehen der Drehfalle 4 in Öffnungsrichtung entlang des Pfeils 22 bewirkt. Die für das entsprechende Drehen der Drehfalle 4 erforderliche Kraft wird bevorzugt durch eine hinreichend stark vorgespannte Feder bereitgestellt, so dass sich die Bereitstellung einer großen Vorspannung durch die Feder 1 0 in der geöffneten Stellung nicht auf die Kraft auswirkt, mit der die Vorrαst-Sperrklinke 1 3 gedreht werden muss, um das Gesperre zu entriegeln .In order to properly move the main catch pawl with the aid of the blocking lever into the locking position, hook-shaped endings 6b and 8a have proven to be particularly suitable. The head of the hook 6b of the main catch pawl acts as a stopper for the catch. The hook tip of the hook 6b is blocked by the head of the hook 8a in the main branch. If the blocking lever 8 is rotated out of the blocking position, the two hooks 6b and 8a engage in one another. Overall, the desired movement can be ensured so particularly reliable. The hooks also cause the lever arm 8b of the blocking lever, which is acted on by the spring 10, to be pressed particularly far outward by the hook 6b when the rotary latch is moved to the open position. This lever arm of the blocking lever is then no longer on the bolt 1 4, whereby the bias is increased, which then presses the blocking lever in the blocking position in the open position of the catch. This increase in the bias by the spring 1 0 (by the corresponding lever arm 8 b away from the bolt 1 4) is not effected by turning the pre-locking pawl 1 3, but by turning the main locking pawl 6 in the direction of arrow 1 out of their locking position. This rotation of the main-locking pawl is in turn effected by turning the rotary latch 4 in the opening direction along the arrow 22. The force required for the corresponding rotation of the rotary latch 4 is preferably provided by a sufficiently strongly biased spring, so that the provision of a large bias by the spring 10 in the open position does not affect the force, with the Vorrαst pawl 1 3 must be rotated to unlock the locking mechanism.
Um die Vorrast - Sperrklinke 1 3 aus ihrer verriegelnden Stellung heraus zu drehen, um so das Schloss zu entriegeln, wird diese an einem Griffbereich 21 erfasst und gedreht. Das Erfassen und Drehen der Vorrast-Sperrklinke 1 3 kann mit Hilfe eines Motors oder durch manuelle Betätigung erfolgen .In order to rotate the pre-locking pawl 1 3 out of its locking position, so as to unlock the lock, it is detected at a handle portion 21 and rotated. The detection and rotation of the pre-locking pawl 1 3 can be done by means of a motor or by manual operation.
In der Figur 2 wird das Schloss aus Figur 1 gezeigt. Allerdings ist die Vorrast- Sperrklinke 1 3 nun nicht transparent dargestellt. Diese verdeckt daher teilweise vor allem die Hauptrast-Sperrklinke 1 3.In FIG. 2, the lock of FIG. 1 is shown. However, the pre-locking pawl 1 3 is now not shown transparent. This therefore partially obscures, in particular, the main catch pawl 1 3.
In der Figur 3 wird die Stellung der Drehfalle 4, der Hauptrast-Sperrklinke 6, des Blockadehebels 8, der Feder 1 0 und des Schließbolzens 3 in der geöffneten Stellung verdeutlicht. Außerdem wird die Stellung der Vorrast- Sperrklinke 1 3 durch eine transparente Darstellung skizziert. Der Schließbolzen 3 kann nun aus dem Einlaufschlitz heraus bewegt und die zugehörige Tür oder Klappe geöffnet werden . Die Spitze des Hakens 6b der Hauptrast-Sperrklinke drückt den hakenförmigen Hebelarm 8a und damit auch den Hebelarm 8b des Blockadehebels 8 weit nach außen . Der Federarm 1 0b wird damit ebenfalls weit nach außen gedrückt und die Feder 1 0 insgesamt stark vorgespannt. Die seitliche Spitze 4b der seitlichen Kontur 4a, die sich bis zum Eckpunkt 4c erstreckt, trägt dafür Sorge, dass der Hebel 8b durch den Haken 6b besonders weit nach außen gedrückt wird und so die Feder 1 0 besonders stark vorgespannt wird . Die Figur 3 verdeutlicht außerdem, dass die Vorrast-Sperrklinke 1 3 nicht zur vergrößerten Vorspannung der Feder 1 0 beiträgt.In the figure 3, the position of the rotary latch 4, the main latch pawl 6, the blocking lever 8, the spring 1 0 and the locking pin 3 is illustrated in the open position. In addition, the position of the pre-locking pawl 1 3 is outlined by a transparent representation. The locking pin 3 can now be moved out of the inlet slot and the associated door or flap can be opened. The tip of the hook 6b of the main catch pawl pushes the hook-shaped lever arm 8a and thus also the lever arm 8b of the blocking lever 8 far outward. The spring arm 1 0b is thus also pressed far outward and biased the spring 1 0 total strong. The lateral tip 4b of the lateral contour 4a, which extends to the corner point 4c, ensures that the lever 8b is pushed particularly far outward by the hook 6b and thus the spring 10 is particularly strongly biased. The figure 3 also illustrates that the pre-locking pawl 1 3 does not contribute to the increased bias of the spring 1 0.
Wird eine Fahrzeugtür, durch die Personen ein- und aussteigen, oder Fahrzeugklappe mit dem Schließbolzen 3 zugeschlagen, so dreht der Drehbolzen 3 die Drehfalle 4 zurück in die Richtung Schließstellung . Die Rückseite des Hakens 6b gleitet dann entlang der seitlichen Kontur 4a, die von dem Eckpunkt 4b bis zu dem Eckpunkt 4c reicht. Dies führt zwar dazu, dass die Vorspannung der Feder 1 0 zunächst etwas nachlässt, da dann auch der Blockadehebel 8 zunächst ein wenig zurück in Richtung blockierende Stellung dreht. Allerding gleitet auch der bolzenförmige Anschlag 1 4 in Richtung seitliche Kontur 1 9 der Vorrast-Sperrklinke 1 3 und gibt so schließlich die Vorrast-Sperrklinke 1 3 frei, so dass diese aufgrund ihrer Vorspannung schließlich in Richtung verriegelnde Stellung dreht und dadurch dann die Vorspannung der Feder 1 0 wieder in dann erwünschter Weise erhöht.If a vehicle door, through which people get in and out, or vehicle flap slammed with the locking pin 3, the pivot pin 3 rotates the rotary latch 4 back in the direction of the closed position. The back of the hook 6b then slides along the lateral contour 4a, the from the vertex 4b to the vertex 4c. Although this leads to the fact that the bias of the spring 1 0 initially decreases somewhat, since then the blocking lever 8 initially turns a little back towards locking position. Allerding also slides the bolt-shaped stop 1 4 in the direction of lateral contour 1 9 of the pre-locking pawl 1 3 and so finally releases the pre-locking pawl 1 3 so that it finally rotates in the direction of locking position due to their bias and thereby the bias of Spring 1 0 again increased in the desired manner.
In der Figur 4 wird eine Zwischenstellung zwischen Öffnungsstellung und Schließstellung der Drehfalle 4 gezeigt. Wird die Drehfalle 4 durch den Bolzen 3 noch etwas weiter in Richtung Schließstellung gedreht, so rastet die hier wiederum transparent dargestellte Vorrast-Sperrklinke 1 3 in ihre verriegelnde Stellung ein und spannt dann die Feder 1 0 wieder stärker vor. Der Rücken des Hakens 6b wird durch den Hebelarm 8a des durch die Feder 1 0 vorgespannten Blockadehebels 8 gegen den seitlichen Konturbereich 4a der Drehfalle gedrückt.In the figure 4, an intermediate position between the open position and closed position of the rotary latch 4 is shown. If the rotary latch 4 is rotated a little further in the direction of the closed position by the bolt 3, the pre-locking pawl 1 3, which in turn is shown in transparent fashion, engages in its locking position and then tightens the spring 10 again more strongly. The back of the hook 6b is pressed by the lever arm 8a of the biased by the spring 1 0 blocking lever 8 against the lateral contour portion 4a of the rotary latch.
Die beiden Hebelarme 8b und 8c verlaufen zwar bogenförmig, aber im Vergleich zum eingangs genannten aus der Druckschrift DE 1 0 2007 003 948 Al bekannten Stand der Technik deutlich gestreckter. In diesem Sinne umfasst der Blockadehebel zwei Hebelarme 8b, 8c, die sich von der Drehachse 9 des Blockadehebels aus gesehen im Wesentlichen in entgegengesetzte Richtungen erstrecken . Der kurze Hebelarm 8c ist tendenziell etwas dicker als der längere Hebelarm 8b ausgestaltet, um so den Schwerpunkt in Richtung Drehachse 9 zu verlagern . Although the two lever arms 8b and 8c extend arcuately, but compared to the initially mentioned from the document DE 1 0 2007 003 948 Al known prior art significantly stretched. In this sense, the blocking lever comprises two lever arms 8b, 8c which extend in opposite directions as viewed from the rotation axis 9 of the blocking lever. The short lever arm 8c tends to be slightly thicker than the longer lever arm 8b, so as to shift the center of gravity in the direction of the axis of rotation 9.
