  • FIG. 1 is a plan view of a housing wall 1 of a vehicle lock shown.
  • 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.

The corresponding door or the flap of the vehicle is thus closed.
  • 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.
  • the catch is not biased by a spring, then at least the locking pin 3 causes a rotational movement of the rotary latch 4 in the open position according to 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.
  • the blocking lever 8 is also mounted on the housing wall 1 and can be rotated about its mounting axis 9.
  • an arm 10b of a spring 10 At a lateral contour region of the blocking lever 8 is an arm 10b of a spring 10 at.
  • the spring 10 is biased so that the arm 10b of the spring 10 urges the blocking lever 8 in the direction of the blocking position shown (in the direction of arrow 11).
  • the rotational movement of the blocking lever 8 caused thereby is limited, as shown, by a stop 12, 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 10a of the spring 10 extends beyond the blocking lever 8.
  • the pre-locking pawl 13 comprises a bolt 14, which extends from the pre-locking pawl in the direction of the housing wall 1. At this pin 14 of the other arm 10a of the spring 10 abuts. The other arm 10a of the spring 10 pushes in the direction of the bolt 14 along the arrow 15. In the main catch of the bolt 14 also bears on a lateral contour region of the blocking lever 8 in order to avoid opening noise. If the pre-locking pawl 13 is rotated in the direction of the arrow 16, the bolt 14 causes the blocking lever 8 is rotated out of the blocking position.
  • the spring arm 10a is also moved. This facilitates the rotation of the blocking lever 8 through the pre-catch pawl 13 from the blocking position because there is no need to overcome counter-pressure of the spring arm 10b. 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 13 as a result of said rotational movement a protruding serving as a stop pin 17 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.
  • the pre-locking pawl 13 may also lock the catch 4 when a protruding pin 18 of the catch 2 impinges on the lateral contour area 19 of the pre-locking pawl 13 and thus prevents rotation of the pawl in the open position according to arrow 22.
  • the pre-locking pawl 13 is biased by a spring, not shown, in the direction of the rotary latch 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.
  • the main catch pawl 6 is preferably not spring loaded.
  • the main catch pawl 6 is then instead rotated by moving the catch 4, the pre-locking pawl 13 and the blocking lever 8 suitably, for example, by a rotational movement of the blocking lever 8 in the locking position (main catch).
  • the corresponding rotation of the blocking lever is effected by the controlled bias of the spring 10.
  • this bias is controlled by appropriately moving the pre-locking pawl and thus provided. Loses that Spring with which the pre-locking pawl is pressed in the direction of its locking position, their effect, so it eliminates 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
  • 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 14, whereby the bias voltage 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 10 (as the corresponding lever arm 8b moves away from the bolt 14) is not caused by turning the pre-locking pawl 13, but by turning the main-latch pawl 6 in the direction of the arrow 16 from its locking position out.
  • 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 corresponding rotation of the rotary latch 4 is preferably provided by a sufficiently 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 pre-locking pawl 13 must be rotated to unlock the locking mechanism.
  • pre-locking pawl 13 In order to turn the pre-locking pawl 13 out of its locking position so as to unlock the lock, it is grasped and turned on a handle portion 21.
  • the detection and rotation of the pre-locking pawl 13 can be done by means of a motor or by manual operation.

  • 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 10b is thus also pressed far outward and the spring 10 is highly biased overall.
  • 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 FIG. 3 also illustrates that the pre-locking pawl 13 does not contribute to the increased bias of the spring 10.
  • Allerding also slides the bolt-shaped stop 14 in the direction of lateral contour 19 of the pre-locking pawl 13 and so finally releases the pre-locking pawl 13 so that it finally rotates in the direction of locking position due to their bias and thereby the bias of the spring 10 back in then desirably increased.
  • FIG. 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, then the pre-locking pawl 13, which in turn is shown transparently, engages in its locking position and then tightens the spring 10 more strongly. The back of the hook 6b is pressed by the lever arm 8a of the biased by the spring 10 blocking lever 8 against the lateral contour portion 4a of the rotary latch.
  • 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.

Description

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. Ein solches Schloss ist aus der Druckschrift DE 10 2007 003 948 A1 bekannt. Eine Drehfalle eines Kraftfahrzeugschlosses verfügt über einen gabelförmigen Einlaufschlitz, in den ein Schließbolzen einer Fahrzeugtür oder einer Fahrzeugklappe gelangt, wenn die Fahrzeugtür oder 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.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 from the document DE 10 2007 003 948 A1 known. A 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 vehicle door 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 10 2007 003 948 A1 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 in the from the publication DE 10 2007 003 948 A1 known lock for the main catch pawl required as the catch and the main catch pawl so are designed so that the pawl in the main catch urges the main-locking pawl from the locking position.

Der aus der Druckschrift DE 10 2007 003 948 A1 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 from the publication DE 10 2007 003 948 A1 known, 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 die Drehfalle aufgrund einer entsprechenden Vorspannung von der Hauptrast in ihre geöffnete Stellung. Der Schließbolzen kann nun wieder aus dem Einlaufschlitz heraus bewegt und die entsprechende Fahrzeugtür oder Fahrzeugklappe geöffnet werden.To 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. Following this, the catch rotates 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 10 2007 003 948 A1 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.The from the publication DE 10 2007 003 948 A1 known pre-locking pawl 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.

Ein Schloss gemäß dem Oberbegriff des Anspruchs 1 ist aus der Druckschrift DE 20 2006 012 091 U bekannt.Weiterhin offenbart die Druckschrift GB 2 433 768 ein Schloss mit einem mehrarmigen Blockadehebel. Es ist Aufgabe der Erfindung, ein gut funktionierendes Schloss für ein Kraftfahrzeug bereitzustellen.A lock according to the preamble of claim 1 is from the document DE 20 2006 012 091 U bekannt.Nehin discloses the document GB 2 433 768 a lock with a multi-arm blockage lever. 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. Der drehbar gelagerte Blockadehebel weist 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. Erfindungsgemäß verfügt der Blockadehebel über einen dritten Hebelarm für das Bewegen und blockieren der Sperrklinke. Der dritte Hebelarm ist kürzer als die beiden anderen genannten Hebelarme, um den Schwerpunkt so wenig wie möglich von der Drehachse weg zu verlagern . Mit diesem dritten Hebelarm wird die Sperrklinke und zwar vorzugsweise die Hauptrast-Sperrklinke in die verriegelnde Stellung bewegt und nach Erreichen der verriegelnden Stellung blockiert. Dieser dritte Hebelarm ist insbesondere aus genannten Gründen hakenförmig ausgestaltet.The claimed lock 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 main catch pawl for a 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. The rotatably mounted blocking lever has at least two lever arms which, viewed from the rotational axis, extend in substantially 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 better. According to the invention the blocking lever has a third lever arm for moving and blocking the pawl. The third lever arm is shorter than the other two mentioned lever arms in order to shift the center of gravity as little as possible away from the axis of rotation. With this third lever arm, the pawl, preferably the main-locking pawl is moved to the locking position and blocked after reaching the locking position. This third lever arm is configured hook-shaped in particular for the reasons mentioned.

In einer Ausführungsform der Erfindung wirkt auf einen der entgegengesetzten 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 Blockadehebels zu bewirken vermag.In one embodiment of the invention acts on one of the opposite 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 easily able to effect the desired rotational movement of the blocking lever.

In einer Ausführungsform der Erfindung gibt es einen Anschlag für einen der beiden entgegengesetzten 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 opposite 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.Below is a in the FIGS. 1 to 4 shown embodiment of the invention 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.In the FIG. 1 is a plan view of a housing wall 1 of a vehicle lock shown. 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 FIG. 1 the main catch is shown, in which the locking bolt 3 located in the housing wall inlet slot 2 is enclosed by the inlet slot of the rotary latch so that the locking bolt 3 can no longer 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.

lst die Drehfalle 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.If the catch is not biased by a spring, then at least the locking pin 3 causes a rotational movement of the rotary latch 4 in the open position according to 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 10b einer Feder 10 an. Die Feder 10 ist so vorgespannt, dass der Arm 10b der Feder 10 den Blockadehebel 8 in Richtung der gezeigten Blockadestellung (in Richtung Pfeil 11) drängt. Begrenzt wird die dadurch verursachte Drehbewegung des Blockadehebels 8 wie gezeigt durch einen Anschlag 12, der in Form eines vorstehenden Bolzens an der Gehäusewand 1 befestigt ist. Die Feder 10 ist überwiegend seitlich neben dem Blockadehebel 8 sowie neben einer Vorrastsperrklinke angeordnet, um eine geringe Bauhöhe zu ermöglichen. Lediglich ein Arm 10a der Feder 10 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 10b of a spring 10 at. The spring 10 is biased so that the arm 10b of the spring 10 urges the blocking lever 8 in the direction of the blocking position shown (in the direction of arrow 11). The rotational movement of the blocking lever 8 caused thereby is limited, as shown, by a stop 12, 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 10a of the spring 10 extends beyond the blocking lever 8.

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 13 der Vorrast - Sperrklinke ist punktiert angedeutet. Die Vorrast - Sperrklinke 13 umfasst einen Bolzen 14, der sich von der Vorrast - Sperrklinke in Richtung Gehäusewand 1 erstreckt. An diesem Bolzen 14 liegt der andere Arm 10a der Feder 10 an. Der andere Arm 10a der Feder 10 drückt in Richtung des Bolzens 14 entlang des Pfeils 15. In der Hauptrast liegt der Bolzen 14 außerdem an einem seitlichen Konturbereich des Blockadehebels 8 an, um Öffnungsgeräusche zu vermeiden. Wird die Vorrast - Sperrklinke 13 in Richtung des Pfeils 16 gedreht, so bewirkt der Bolzen 14, dass der Blockadehebel 8 aus der blockierenden Stellung heraus gedreht wird.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 13 of the pre-locking pawl is indicated by dotted lines. The pre-locking pawl 13 comprises a bolt 14, which extends from the pre-locking pawl in the direction of the housing wall 1. At this pin 14 of the other arm 10a of the spring 10 abuts. The other arm 10a of the spring 10 pushes in the direction of the bolt 14 along the arrow 15. In the main catch of the bolt 14 also bears on a lateral contour region of the blocking lever 8 in order to avoid opening noise. If the pre-locking pawl 13 is rotated in the direction of the arrow 16, the bolt 14 causes the blocking lever 8 is rotated out of the blocking position.

Zugleich wird aufgrund der Drehbewegung der Vorrast - Sperrklinke 13 der Federarm 10a mit bewegt. Dies erleichtert das Drehen des Blockadehebels 8 durch die Sperrklinke 13 für die Vorrast aus der blockierenden Stellung heraus, weil kein Gegendruck des Federarms 10b 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 13 infolge der genannten Drehbewegung einen vorstehenden als Anschlag dienenden Bolzen 17, 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.At the same time, due to the rotational movement of the pre-locking pawl 13, the spring arm 10a is also moved. This facilitates the rotation of the blocking lever 8 through the pre-catch pawl 13 from the blocking position because there is no need to overcome counter-pressure of the spring arm 10b. 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 13 as a result of said rotational movement a protruding serving as a stop pin 17 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 13 kann die Drehfalle 4 ebenfalls verriegeln, wenn ein vorstehender Bolzen 18 der Drehfalle 2 auf den seitlichen Konturbereich 19 der Vorrast-Sperrklinke 13 auftrifft und so ein Drehen der Sperrklinke in Richtung geöffnete Stellung gemäß Pfeil 22 verhindert. Die Vorrast-Sperrklinke 13 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 13 may also lock the catch 4 when a protruding pin 18 of the catch 2 impinges on the lateral contour area 19 of the pre-locking pawl 13 and thus prevents rotation of the pawl in the open position according to arrow 22. The pre-locking pawl 13 is biased by a spring, not shown, in the direction of the rotary latch 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 13 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 10 bewirkt. Diese Vorspannung wird allerdings durch entsprechendes Bewegen der Vorrast- Sperrklinke gesteuert und so bereitgestellt. Verliert die Feder, mit der die Vorrast-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 by moving the catch 4, the pre-locking pawl 13 and the blocking lever 8 suitably, for example, by a rotational movement of the blocking lever 8 in the locking position (main catch). The corresponding rotation of the blocking lever is effected by the controlled bias of the spring 10. However, this bias is controlled by appropriately moving the pre-locking pawl and thus provided. Loses that Spring with which the pre-locking pawl is pressed in the direction of its locking position, their effect, so it eliminates 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 10 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 14 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 10 (indem sich der entsprechende Hebelarm 8b von dem Bolzen 14 entfernt), wird nicht durch Drehen der Vorrast-Sperrklinke 13 bewirkt, sondern durch Drehen der Hauptrast-Sperrklinke 6 in Richtung des Pfeils 16 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 10 in der geöffneten Stellung nicht auf die Kraft auswirkt, mit der die Vorrast-Sperrklinke 13 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 14, whereby the bias voltage 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 10 (as the corresponding lever arm 8b moves away from the bolt 14) is not caused by turning the pre-locking pawl 13, but by turning the main-latch pawl 6 in the direction of the arrow 16 from its locking position out. 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 corresponding rotation of the rotary latch 4 is preferably provided by a sufficiently 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 pre-locking pawl 13 must be rotated to unlock the locking mechanism.

Um die Vorrast - Sperrklinke 13 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 13 kann mit Hilfe eines Motors oder durch manuelle Betätigung erfolgen.In order to turn the pre-locking pawl 13 out of its locking position so as to unlock the lock, it is grasped and turned on a handle portion 21. The detection and rotation of the pre-locking pawl 13 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 13 nun nicht transparent dargestellt. Diese verdeckt daher teilweise vor allem die Hauptrast-Sperrklinke 13.In the FIG. 2 the castle will be off FIG. 1 shown. However, the pre-locking pawl 13 is now not transparent. This therefore partially conceals especially the main catch pawl 13th

In der Figur 3 wird die Stellung der Drehfalle 4, der Hauptrast-Sperrklinke 6, des Blockadehebels 8, der Feder 10 und des Schließbolzens 3 in der geöffneten Stellung verdeutlicht. Außerdem wird die Stellung der Vorrast-Sperrklinke 13 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 10b wird damit ebenfalls weit nach außen gedrückt und die Feder 10 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 10 besonders stark vorgespannt wird. Die Figur 3 verdeutlicht außerdem, dass die Vorrast-Sperrklinke 13 nicht zur vergrößerten Vorspannung der Feder 10 beiträgt.In the FIG. 3 the position of the rotary latch 4, the main locking pawl 6, the blocking lever 8, the spring 10 and the locking pin 3 is illustrated in the open position. In addition, the position of the pre-locking pawl 13 is sketched 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 10b is thus also pressed far outward and the spring 10 is highly biased overall. 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 FIG. 3 also illustrates that the pre-locking pawl 13 does not contribute to the increased bias of the spring 10.

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 10 zunächst etwas nachlässt, da dann auch der Blockadehebel 8 zunächst ein wenig zurück in Richtung blockierende Stellung dreht. Allerding gleitet auch der bolzenförmige Anschlag 14 in Richtung seitliche Kontur 19 der Vorrast-Sperrklinke 13 und gibt so schließlich die Vorrast-Sperrklinke 13 frei, so dass diese aufgrund ihrer Vorspannung schließlich in Richtung verriegelnde Stellung dreht und dadurch dann die Vorspannung der Feder 10 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 10 initially decreases a bit, since then the blocking lever 8 initially rotates a little back in the direction blocking position. Allerding also slides the bolt-shaped stop 14 in the direction of lateral contour 19 of the pre-locking pawl 13 and so finally releases the pre-locking pawl 13 so that it finally rotates in the direction of locking position due to their bias and thereby the bias of the spring 10 back in then desirably increased.

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 13 in ihre verriegelnde Stellung ein und spannt dann die Feder 10 wieder stärker vor. Der Rücken des Hakens 6b wird durch den Hebelarm 8a des durch die Feder 10 vorgespannten Blockadehebels 8 gegen den seitlichen Konturbereich 4a der Drehfalle gedrückt.In the FIG. 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, then the pre-locking pawl 13, which in turn is shown transparently, engages in its locking position and then tightens the spring 10 more strongly. The back of the hook 6b is pressed by the lever arm 8a of the biased by the spring 10 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 10 2007 003 948 A1 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 in comparison to the above-mentioned from the publication DE 10 2007 003 948 A1 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.
