  • One end of the locking lever 21 passes in excessive acceleration so in one of the locking positions (25, 26, 27), which is effected by a rigidly attached to the lock case 1 locking contour 18. This prevents that the release lever 5 can be further rotated clockwise for a move out of the blocking lever 7 from its blocking position.

Description

Die Erfindung betrifft ein Schloss für ein Kraftfahrzeug mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a lock for a motor vehicle having the features of the preamble of claim 1.

Ein Schloss für ein Kraftfahrzeug umfasst ein Gesperre mit einer drehbar gelagerten Drehfalle für die Aufnahme eines Schließbolzens, der auch Schlosshalter genannt wird. Das Gesperre weist weiter eine Sperrklinke auf, mit der die Drehfalle für ein Halten des Schließbolzens verrastet werden kann.A lock for a motor vehicle includes a locking mechanism with a rotatably mounted rotary latch for receiving a locking bolt, which is also called lock holder. The locking mechanism further has a pawl with which the catch can be latched for holding the locking bolt.

Die Drehfalle eines Kraftfahrzeugschlosses verfügt üblicherweise über einen durch Lastarm und Fangarm gebildeten gabelförmigen Einlaufschlitz (auch Einlaufmaul genannt), in den der Schließbolzen einer Fahrzeugtür oder Klappe, beispielsweise Motorhaube oder Kofferraumklappe, gelangt, wenn die Tür oder Klappe geschlossen wird. Der Schließbolzen bzw. Schlosshalter dreht dann die Drehfalle von einer Öffnungsstellung in Richtung Schließstellung, bis die Sperrklinke die Drehfalle verrastet. Diese Position wird Rastposition genannt. Der Schließbolzen kann den Einlaufschlitz der Drehfalle dann nicht verlassen.The catch of a motor vehicle lock usually has a bifurcated inlet slot formed by load arm and catching arm (also called infeed mouth) into which the locking bolt of a vehicle door or flap, for example bonnet or boot lid, arrives when the door or flap is closed. The locking pin or lock holder then rotates the catch from an open position towards the closed position until the pawl locks the catch. This position is called detent position. The locking bolt can then not leave the inlet slot of the rotary latch.

Ein Schloss kann darüber hinaus einen Blockadehebel umfassen, der die Sperrklinke in ihrer Rastposition zu blockieren vermag. Der Blockadehebel muss aus seiner blockierenden Position heraus geschwenkt bzw. heraus gedreht werden, damit die Sperrklinke ihre Rastposition für ein Öffnen des Gesperres verlassen kann.A lock may also include a blocking lever capable of blocking the pawl in its detent position. The blockage lever must be pivoted out of its blocking position or turned out so that the pawl can leave its locking position for opening the locking mechanism.

Es gibt Schlösser, bei denen die Drehfalle ein öffnendes Moment in die Sperrklinke einzuleiten vermag, wenn diese sich in ihrer Rastposition befindet. Bei einem solchen Schloss ist ein Blockadehebel erforderlich, um das Gesperre verrasten zu können. Solche Schlösser können mit geringem Kraftaufwand geöffnet werden.There are locks in which the catch is able to initiate an opening moment in the pawl when it is in its detent position. In such a lock a blocking lever is required, to lock the locking mechanism. Such locks can be opened with little effort.

Es gibt Kraftfahrzeugschlösser mit zwei Rastpositionen und zwar einer Vorrastposition und einer Hauptrastposition. Die Vorrastposition dient dazu, die entsprechende Tür oder Klappe abzufangen, wenn diese beim Schließen die Hauptrastposition nicht erreicht. Wird die Drehfalle ausgehend von der Vorrastposition entsprechend weiter gedreht, so erreicht diese schließlich die Hauptrastposition.There are motor vehicle locks with two detent positions, namely a pre-detent position and a main detent position. The pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing. If the rotary latch is rotated further starting from the pre-latching position, this finally reaches the main latching position.

Ein Schloss verfügt grundsätzlich über einen Auslösehebel, der betätigt wird, um ein Gesperre zu öffnen bzw. zu entrasten. Ein solcher Auslösehebel ist typischerweise mit einem Griff einer Tür oder Klappe verbunden. Wird der Griff betätigt, so wird der Auslösehebel betätigt bzw. verschwenkt, um das das Gesperre zu entrasten und damit das Schloss zu öffnen.A lock basically has a release lever that is operated to open or unlatch a ratchet. Such a trigger lever is typically connected to a handle of a door or flap. If the handle is pressed, the release lever is actuated or pivoted to detent the lock and thus open the lock.

In einem Crashfall kann der Griff unplanmäßig betätigt werden, was zu einem Öffnen des Gesperres führen würde. Es sollte sichergestellt sein, dass ein solches Schloss sich dann nicht unplanmäßig öffnet.In the event of a crash, the handle can be operated unscheduled, which would lead to an opening of the locking mechanism. It should be ensured that such a lock then does not open unplanned.

Um sicherzustellen, dass sich ein Schloss nicht unplanmäßig in einem Crashfall öffnet, wird gemäß der Druckschrift EP 1518983A2 ein Schloss mit einem Gesperre vorgesehen, das wenigstens einen Betätigungshebel zum Auslösen bzw. Öffnen des Gesperres, also einen Auslösehebel, umfasst. Das Schloss weist ferner einen Sperrhebel auf, der den Betätigungshebel bei vorgegebenen Fahrzeugbeschleunigungen blockiert.To ensure that a lock does not open unscheduled in a crash, is in accordance with the document EP 1518983A2 a lock provided with a locking mechanism, which comprises at least one actuating lever for triggering or opening the locking mechanism, that is, a release lever. The lock further includes a locking lever which blocks the operating lever at predetermined vehicle accelerations.

In einem Crashfall treten im Vergleich zu einem üblichen Öffnen besonders hohe Beschleunigungen auf. Blockiert der Betätigungshebel nur bei hohen Fahrzeugbeschleunigungen, wie diese in einem Crashfall auftreten, so kann ein unbeabsichtigtes Öffnen des Gesperres im Crashfall verhindert werden. Im Fall eines üblichen Betätigens des Türgriffs wird der Betätigungshebel mangels hoher Beschleunigung nicht blockiert, um dann ein Öffnen des Schlosses zu ermöglichen.In the event of a crash, particularly high accelerations occur in comparison with a conventional opening. Blocked the operating lever only at high vehicle accelerations, as they occur in a crash, so accidental opening of the lock in Crash case can be prevented. In the case of a usual operation of the door handle, the operating lever is not blocked for lack of high acceleration, to then allow opening of the lock.

Bei einem Crashfall kann auf die beim Aufprall übermäßig starken Beschleunigungskräfte ein Rückprall folgen, welcher auch Bouncen genannt wird. Durch verzögerten oder wiederholten Rückprall, insbesondere verbunden mit Änderungen der Beschleunigungskräfte und -richtungen, kann es zu einem Versagen einer Sperreinrichtung bei hohen Beschleunigungen kommen, die ein unplanmäßiges Öffnen des Schlosses im Crashfall vermeiden soll.In the event of a crash, the acceleration forces which are excessively strong on impact can be followed by a rebound, which is also called bouncing. By delayed or repeated rebound, in particular associated with changes in the acceleration forces and directions, there may be a failure of a locking device at high accelerations, which should prevent unscheduled opening of the lock in the event of a crash.

Die Druckschrift US 2010/237633 A1 offenbart eine Verriegelungsvorrichtung für eine Griffanordnung einer Kraftfahrzeugtür, bei der ein Trägheitshebel durch eine Feder in einer Sperrstellung gedrückt wird.The publication US 2010/237633 A1 discloses a locking device for a handle assembly of a motor vehicle door in which an inertia lever is pressed by a spring in a locking position.

Die Druckschrift DE 10 2011 010816 A1 offenbart ein Kraftfahrzeugtürverschluss, der mit einem Gesperre und einem auf das Gesperre arbeitenden Betätigungshebelwerk mit einem Auslösehebel sowie mit einem Sperrhebel ausgerüstet ist. Der Sperrhebel blockiert das Gesperre zumindest bei auftretenden Beschleunigungskräften vorgegebener Größe, beispielsweise bei einem Unfall bzw. Crash-Fall.The publication DE 10 2011 010816 A1 discloses a motor vehicle door latch equipped with a ratchet and an operating lever mechanism operating on the ratchet with a release lever and with a locking lever. The locking lever blocks the ratchet at least when occurring acceleration forces of predetermined size, for example in an accident or crash case.

Durch den Gegenstand der vorliegenden Erfindung soll ein Schloss bereitgestellt werden, bei dem im Crashfall ein unplanmäßiges Öffnen vermieden wird.The object of the present invention is to provide a lock in which an unplanned opening is avoided in the event of a crash.

Zur Lösung der Aufgabe dient ein Schloss mit den Merkmalen des Hauptanspruchs. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.To solve the problem is a lock with the features of the main claim. Advantageous embodiments will be apparent from the dependent claims.

Zur Lösung der Aufgabe wird ein Schloss mit einem Gesperre bereitgestellt, welches eine Drehfalle und eine Sperrklinke für ein Verrasten der Drehfalle umfasst. Das Schloss umfasst weiter einen Blockadehebel, der die Sperrklinke zu blockieren vermag, wenn diese sich in ihrer Rastposition befindet. Darüber hinaus gibt es einen Auslösehebel für ein Öffnen bzw. Auslösen des Gesperres.To achieve the object, a lock is provided with a locking mechanism, which comprises a rotary latch and a pawl for locking the rotary latch. The lock further includes a blocking lever which is capable of blocking the pawl when in its latching position. In addition, there is a release lever for opening or releasing the locking mechanism.

Optional kann das Schoss eine Vorrastsperrklinke umfassen, welche grundsätzlich identisch oder einstückig mit dem Auslösehebel ausgeführt sein kann.Optionally, the lap may comprise a Vorrastsperrklinke, which may be basically identical or integral with the release lever.

Wird der Auslösehebel betätigt, so wird dadurch der Blockadehebel aus seiner blockierenden Position heraus bewegt, wenn nicht übermäßig stark beschleunigt wird. Die übermäßig starke Beschleunigung bezieht sich vorzugsweise auf den Auslösehebel des Schlosses. Das Schloss kann aber auch so sein, dass auf eine übermäßig starke Beschleunigung des Griffs einer zugehörigen Tür oder Klappe abgestellt wird und in Abhängigkeit von dieser Beschleunigung die Sperreinrichtung ein Öffnen ermöglicht oder verhindert.When the release lever is actuated, the blockage lever is thereby moved out of its blocking position, if not accelerated excessively. The excessive acceleration preferably refers to the release lever of the lock. However, the lock can also be such that an excessively strong acceleration of the handle of an associated door or flap is turned off and in Depending on this acceleration, the locking device allows or prevents opening.

In einer Ausführungsform kann die Sperrklinke unmittelbar durch den Auslösehebel aus ihrer Raststellung herausbewegt werden. Diese Ausführungsform umfasst in der Regel keinen Blockadehebel für ein Blockieren einer Sperrklinke.In one embodiment, the pawl can be moved out of its detent position directly by the release lever. This embodiment usually does not include a blocking lever for blocking a pawl.

Treten übermäßig starke Beschleunigungen zum Beispiel des Auslösehebels auf, wie diese durch einen Crash verursacht werden können, so verhindert die Sperreinrichtung des Schlosses, dass sich das Schloss unplanmäßig zu öffnen vermag. Insbesondere verhindert die Sperreinrichtung, dass der Auslösehebel einen Blockadehebel des Schlosses, der eine Sperrklinke in ihrer Raststellung zu blockieren vermag, aus seiner blockierenden Position heraus zu bewegen vermag. Das Schloss kann sich daher nicht öffnen, wenn im Fall eines Crashs beispielsweise der Auslösehebel und/oder ein zugehöriger Griff einer Tür oder Klappe entsprechend stark beschleunigt werden.If excessively high accelerations occur, for example, of the release lever, as can be caused by a crash, the lock mechanism of the lock prevents the lock from opening unscheduledly. In particular, the locking device prevents the release lever is able to move a blocking lever of the lock, which is able to block a pawl in its locked position, out of its blocking position out. Therefore, the lock can not open, for example, in the event of a crash, the release lever and / or an associated handle a door or flap are accelerated accordingly strong.

In einer Ausführungsform der Erfindung umfasst die Sperreinrichtung mindestens zwei sperrende Stellungen. Befindet sich die Sperreinrichtung in einer ersten sperrenden Stellung beispielsweise infolge eines übermäßig stark beschleunigten Auslösehebels, insbesondere hervorgerufen durch einen Aufprall bei einem Crash, und löst sich die Sperreinrichtung aus der ersten sperrenden Stellung, beispielsweise aufgrund eines Rückpralls, insbesondere verzögerter und/oder wiederholter Rückprall, so vermag die Sperreinrichtung durch Einnehmen einer zweiten oder weiteren sperrenden Stellung weiterhin zu vermeiden, dass sich das Gesperre öffnet, also in einer Ausführungsform der Auslösehebel den Blockadehebel aus seiner blockierenden Position heraus bewegt. Durch das Vorsehen einer Sperreinrichtung mit mindestens zwei sperrenden Stellungen wird folglich ein unplanmäßiges Öffnen des Schlosses im Crashfall auch bei Auftreten von Rückpralleffekten vermieden.In one embodiment of the invention, the locking device comprises at least two locking positions. Is the locking device in a first blocking position, for example due to an excessively accelerated release lever, in particular caused by an impact in a crash, and releases the locking device from the first locking position, for example due to a rebound, in particular delayed and / or repeated rebound Thus, the locking device can continue to avoid by taking a second or further blocking position that the locking mechanism opens, so in one embodiment, the release lever moves the blocking lever out of its blocking position. By providing a locking device with at least two locking positions is consequently an unplanned Opening the lock in the event of a crash avoided even when rebound effects occur.

Die Sperreinrichtung umfasst einen Trägheitshebel und einen Sperrhebel. Trägheitshebel und Sperrhebel sind so miteinander verbunden, dass der Trägheitshebel nur dann zusammen mit dem Sperrhebel durch Betätigen des Auslösehebels oder durch Betätigen eines Griffs einer Tür oder Klappe bewegt wird, wenn der Auslösehebel in üblicher Weise beschleunigt wird, wie dies bei einem üblichen Betätigen des Türgriffs der Fall ist, also nicht übermäßig stark beschleunigt. In einem solchen Fall erfolgt die gemeinsame Bewegung von Trägheitshebel und Sperrhebel derart, dass der Sperrhebel das Öffnen des Gesperres nicht zu verhindern vermag. Wird ein Griff einer Tür oder einer Klappe durch einen Benutzer des Fahrzeugs betätigt, so werden der Griff und ein damit verbundener Auslösehebel grundsätzlich nicht übermäßig beschleunigt.The locking device comprises an inertia lever and a locking lever. Inertial lever and locking lever are interconnected so that the inertia lever is moved together with the locking lever only by operating the trigger lever or by operating a handle of a door or flap when the trigger lever is accelerated in a conventional manner, as in a conventional operation of the door handle the case is so not overly accelerated. In such a case, the joint movement of the inertia lever and locking lever takes place in such a way that the locking lever can not prevent the opening of the locking mechanism. When a handle of a door or flap is actuated by a user of the vehicle, the handle and associated trip lever are generally not excessively accelerated.

Der Trägheitshebel und Sperrhebel sind so miteinander verbunden, dass bei stark beschleunigtem Auslösehebel oder stark beschleunigtem Griff einer Tür oder Klappe, wie dies in einem Crashfall möglich ist, aufgrund der Trägheit des Trägheitshebels nur der Sperrhebel bewegt wird und zwar in eine der sperrenden Stellungen der Sperreinrichtung, die ein weiteres Verschwenken des Auslösehebels bzw. des Griffs derart blockiert, dass ein Öffnen des Gesperres vermieden wird.The inertia lever and locking lever are connected to each other so that when the release lever or strongly accelerated door or flap handle, as is possible in a crash, due to the inertia of the inertia lever only the locking lever is moved in one of the blocking positions of the locking device , which blocks further pivoting of the release lever or the handle such that an opening of the locking mechanism is avoided.

Die Sperreinrichtung umfasst eine Feder, die den Trägheitshebel und den Sperrhebel so miteinander verbindet, dass der Trägheitshebel nur dann zusammen mit dem Sperrhebel durch Betätigen des Auslösehebels oder durch Betätigen des Griffs bewegt werden kann, wenn der Auslösehebel oder der Griff in üblicher Weise beschleunigt wird. Auf technisch einfache Weise wird so vermieden, dass sich ein Schloss in einem Crashfall unbeabsichtigt zu öffnen vermag.The locking means comprises a spring which interconnects the inertia lever and the lock lever so that the inertia lever can only be moved together with the lock lever by operating the release lever or by operating the handle when the release lever or handle is accelerated in a conventional manner. In a technically simple way so avoided that a lock can inadvertently open in the event of a crash.

Ein Schenkel der Feder ist in einer Ausführungsform der Erfindung mit dem Trägheitshebel verbunden. Eine solche Verbindung liegt insbesondere dann vor, wenn der Schenkel der Feder vorzugsweise vorgespannt an einer Kontur des Trägheitshebels anliegt.One leg of the spring is connected in one embodiment of the invention with the inertia lever. Such a connection is in particular present when the leg of the spring is preferably biased against a contour of the inertia lever.

Ein anderer Schenkel der Feder ist mit dem Sperrhebel verbunden. Eine solche Verbindung liegt insbesondere dann vor, wenn der Schenkel der Feder vorzugsweise vorgespannt an einer Kontur des Sperrhebels anliegt. Bei geringen Beschleunigungen wirkt die Feder wie eine starre Verbindung zwischen Sperrhebel und Trägheitshebel. Bei geringen Beschleunigungen werden daher Sperrhebel und Trägheitshebel gemeinsam durch Betätigen des Auslösehebels oder Griffs für ein Öffnen des Gesperres bewegt.Another leg of the spring is connected to the locking lever. Such a connection is present in particular when the leg of the spring preferably biased rests against a contour of the locking lever. At low accelerations, the spring acts as a rigid connection between the locking lever and the inertia lever. At low accelerations therefore locking lever and inertia lever are moved together by pressing the release lever or handle for opening the locking mechanism.

Bei starker Beschleunigung wird aufgrund der Trägheit des Trägheitshebel die Feder derart verformt, dass nur der Sperrhebel bewegt wird, nicht aber der Trägheitshebel. Insbesondere wird die Feder bei entsprechend starker Beschleunigung weiter vorgespannt. Wird der Sperrhebel unabhängig vom Trägheitshebel bewegt, so gelangt der Sperrhebel dann in seine sperrende Position. In der sperrenden Position wird verhindert, dass der Auslösehebel oder Griff derart weiter verdreht werden können, dass hierdurch ein Öffnen des Gesperres bewirkt wird.During high acceleration, due to the inertia of the inertia lever, the spring is deformed so that only the locking lever is moved, but not the inertia lever. In particular, the spring is further biased at a correspondingly strong acceleration. If the locking lever is moved independently of the inertia lever, then the locking lever then enters its locking position. In the blocking position, it is prevented that the release lever or handle can be further rotated in such a way that this causes an opening of the locking mechanism.

In einer Ausführungsform umfasst der Sperrhebel einen Mitnehmer, der vom Auslösehebel für ein Bewegen des Sperrhebels bewegt werden kann. Wird der Auslösehebel betätigt, so werden der Mitnehmer und damit der Sperrhebel bewegt.In one embodiment, the locking lever comprises a driver that can be moved by the release lever for moving the locking lever. If the release lever is actuated, the driver and thus the locking lever are moved.

In einer Ausführungsform reicht der Mitnehmer des Sperrhebels durch ein Langloch des Trägheitshebels hindurch, um so eine Relativbewegung zwischen Sperrhebel und Trägheitshebel zu ermöglichen.In one embodiment, the catch of the locking lever passes through a slot of the inertia lever, so as to allow a relative movement between the locking lever and the inertia lever.

In einer Ausführungsform ist die Masse des Trägheitshebels um ein Mehrfaches größer als die Masse des Sperrhebels, um so zuverlässig zu erreichen, dass der Trägheitshebel nur bei geringen Beschleunigungen des Auslösehebels bewegt wird. Vorzugsweise ist die Masse des Trägheitshebels um das Zweifache, bevorzugt um das Dreifache, noch bevorzugter um das Vierfache größer als die Masse des Sperrhebels.In one embodiment, the mass of the inertia lever is several times greater than the mass of the locking lever so as to achieve reliable, that the inertia lever is moved only at low accelerations of the release lever. Preferably, the mass of the inertia lever is two times, preferably three times, more preferably four times greater than the mass of the locking lever.

In einer Ausführungsform verfügt das Schloss über eine Sperrkontur, die vorzugsweise starr mit einem Schlosskasten des Schlosses verbunden ist. Die Sperrkontur dient dem Sperren des Sperrhebels, wenn der Auslösehebel und/oder Griff übermäßig stark beschleunigt wird. Wird der Sperrhebel durch die Sperrkontur gesperrt und befindet sich somit in einer sperrenden Stellung, so kann der Auslösehebel oder Griff nicht weiter derart verdreht werden, dass dadurch das Gesperre geöffnet wird.In one embodiment, the lock has a locking contour, which is preferably rigidly connected to a lock case of the castle. The locking contour serves to lock the locking lever when the trigger lever and / or handle is excessively accelerated. If the locking lever is locked by the locking contour and thus is in a blocking position, the release lever or handle can not be further rotated so that thereby the locking mechanism is opened.

In einer Ausführungsform ist die Sperrkontur an der Innenwand des Schlosskastens flächig anliegend angeordnet, um die Stoßkräfte beim Anschlag des Sperrhebels an die Sperrkontur auf den Schlosskasten zu übertragen. Die Sperrkontur kann so klein dimensioniert werden.In one embodiment, the locking contour is arranged flat against the inner wall of the lock case to transmit the impact forces in the attack of the locking lever to the locking contour on the lock case. The blocking contour can be dimensioned so small.

In einer Ausführungsform ist der der Sperrhebel mit dem Trägheitshebel so verbunden, dass ein Vorsprung des Sperrhebels bei nicht übermäßig starker Beschleunigung des Auslösehebels oder Griffs an die Außenkontur des Trägheitshebels angrenzt, und zwar an jenen Abschnitt der Außenkontur des Trägheitshebels, welcher beim Schwenken für ein Öffnen eines noch in Rastposition verrasteten Gesperres der Sperrkontur zugewandt ist und/oder maximalen Abstand zur Achse des Trägheitshebels aufweist. Durch den geringen Abstand zwischen Sperrhebel und Sperrkontur bei verrastetem Gesperre kann ein besonders schnelles Sperren des Gesperres durch die Sperreinrichtung im Crashfall und bei Rückprall bewirkt werden.In one embodiment, the locking lever is connected to the inertia lever so that a projection of the locking lever adjacent to the outer contour of the inertia lever at not excessive acceleration of the trigger lever or handle, to that portion of the outer contour of the inertia lever, which when pivoting for opening a still locked in locking position locking the locking contour faces and / or maximum distance from the axis of the inertia lever has. Due to the small distance between Locking lever and locking contour with locked locking mechanism, a particularly rapid locking of the locking mechanism by the locking device in the event of a crash and rebound can be effected.

In einer Ausführungsform weist die Sperrkontur einen Bogen auf, dessen Mittelpunkt der Achse des Trägheitshebels entspricht. Vorzugsweise ist der Radius des Bogens um eine Spaltbreite größer als der maximale Abstand der Außenkontur des Trägheitshebels von dessen Achse. Durch den geringen Abstand zwischen Sperrhebel und Sperrkontur bei verrastetem Gesperre kann ein besonders schnelles Sperren des Gesperres durch die Sperreinrichtung im Crashfall und bei Rückprall bewirkt werden.In one embodiment, the locking contour has an arc whose center corresponds to the axis of the inertia lever. Preferably, the radius of the arc is greater by a gap width than the maximum distance of the outer contour of the inertia lever from the axis thereof. Due to the small distance between locking lever and locking contour with locked locking mechanism, a particularly rapid locking of the locking mechanism by the locking device in the event of a crash and rebound can be effected.

In einer Ausführungsform weist der Sperrhebel an dem einem Ende einen Vorsprung auf, der in radiale Richtung nach außen zeigt und zwar bezogen auf die Achse des Trägheitshebels. Wird der Sperrhebel aufgrund übermäßig starker Beschleunigung des Auslösehebels und/oder Griffs relativ zum Trägheitshebel bewegt, so zeigt der Vorsprung in Richtung der Sperrkontur bzw. ist der Sperrkontur zugewandt und trägt dafür Sorge, dass der Sperrhebel sicher in einer sperrenden Stellung in der Sperrkontur gehalten wird. Dies trägt dazu bei, auf technisch einfache Weise eine Mehrzahl von sperrenden Stellungen bereitzustellen.In one embodiment, the locking lever at the one end has a projection which faces radially outward with respect to the axis of the inertia lever. If the locking lever is moved relative to the inertia lever due to excessive acceleration of the release lever and / or handle, so the projection in the direction of the locking contour or is facing the locking contour and ensures that the locking lever is held securely in a locking position in the locking contour , This helps to provide a plurality of blocking positions in a technically simple manner.

In einer Ausführungsform umfasst die Sperrkontur einen Anschlag und/oder mindestens eine Ausnehmung zum Sperren des Sperrhebels, wenn der Auslösehebel und/oder Griff übermäßig stark beschleunigt wird. Die Ausnehmung oder die Ausnehmungen sind vorzugsweise vom Anschlag ausgehend in Umfangrichtung des Trägheitshebels entgegen dem Uhrzeigersinn angeordnet. Eine sperrende Stellung der Sperreinrichtung bzw. des Sperrhebels kann so durch den Anschlag oder die Ausnehmung bzw. Ausnehmungen festgelegt werden. Zunächst einen Anschlag und anschließend zumindest eine Ausnehmung vorzusehen, ist besonders materialsparend.In one embodiment, the locking contour comprises a stop and / or at least one recess for locking the locking lever when the trigger lever and / or handle is excessively accelerated. The recess or the recesses are preferably arranged counter to the clockwise starting from the stop in the circumferential direction of the inertia lever. A blocking position of the locking device or the locking lever can be determined by the stop or the recess or recesses. First, to provide a stop and then at least one recess, is particularly material-saving.

Festlegen einer sperrenden Stellung durch beispielsweise einen Anschlag oder eine Ausnehmung meint, dass eine sperrende Stellung dann von der Sperreinrichtung eingenommen ist, wenn der Anschlag oder die Ausnehmung durch Sperren bzw. Blockade des Sperrhebels ein unplanmäßiges Öffnen des Schlosses zu verhindern vermögen.Setting a blocking position by, for example, a stop or a recess means that a blocking position is then occupied by the locking device when the stop or the recess by blocking or blocking the locking lever are able to prevent unscheduled opening of the lock.

Insbesondere bei Rückpralleffekten kann es vorkommen, dass sich der Sperrhebel aus der sperrenden Stellung am Anschlag der Sperrkontur ungewollt löst. Der Trägheitshebel kann sich dann entgegen dem Uhrzeigersinn bewegen und dazu führen, dass sich das Gesperre unplanmäßig öffnet. Eine Ausnehmung, die vorzugsweise in Umfangrichtung des Trägheitshebels entgegen dem Uhrzeigersinn angeordnet ist, ermöglicht ein erneutes Einrasten bzw. Sperren des Sperrhebels und somit die Vermeidung eines unplanmäßigen Öffnens des Gesperres auch im Fall von Rückpralleffekten.Especially with rebound effects, it may happen that the locking lever unintentionally releases from the blocking position at the stop of the blocking contour. The inertia lever may then move counterclockwise and cause the ratchet to open unscheduled. A recess, which is preferably arranged in the circumferential direction of the inertia lever counterclockwise, allows a renewed locking or locking of the locking lever and thus avoiding an unplanned opening of the locking mechanism, even in the case of rebound effects.

In einer Ausführungsform ist eine Ausnehmung der Sperrkontur dreieckförmig ausgeformt. Durch die dreieckförmige Ausgestaltung einer Ausnehmungen wird eine Selbstzentrierung beim Einrasten des Vorsprungs des Sperrhebels in die Ausnehmung bewirkt und eine besonders hohe Zuverlässigkeit der Sperreinrichtung ermöglicht.In one embodiment, a recess of the locking contour is formed triangular. Due to the triangular configuration of a recesses a self-centering when locking the projection of the locking lever is effected in the recess and allows a particularly high reliability of the locking device.

In einer Ausführungsform weist der Sperrhebel einen dreieckförmigen Vorsprung mit Schrägen an beiden Seiten auf, wobei die entgegen dem Uhrzeigersinn angeordnete Schräge eine geringere Steigung aufweist als die andere gegenüberliegende Schräge des Vorsprungs, welche in Uhrzeigersinn um die Achse des Sperrhebels angeordnet ist. Durch die unterschiedlichen Steigungen der Schrägen des Vorsprungs kann im Crashfall ein besonders sicherer Halt der Sperreinrichtung bzw. des Vorsprungs des Sperrhebels in den sperrenden Stellungen bewirken werden.In one embodiment, the locking lever has a triangular-shaped projection with bevels on both sides, wherein the counter-clockwise slope has a smaller pitch than the other opposite slope of the projection, which is arranged in a clockwise direction about the axis of the locking lever. Due to the different slopes of the slopes of the projection, a particularly secure hold of the locking device or the projection of the locking lever in the blocking positions can be effected in the event of a crash.

In einer Ausführungsform ist eine Ausnehmung der Sperrkontur an den Vorsprung des Sperrhebels in der sperrenden Stellung angepasst, die durch die Ausnehmung festgelegt ist. Insbesondere erfolgt diese Anpassung im Bereich der Überdeckung. Vorzugsweise schließt eine solche Anpassung die Steigungen der Schrägen des Vorsprungs des Sperrhebels mit ein. Die Anpassung der Kontur einer Ausnehmung der Sperrkontur an die Kontur des Vorsprungs des Sperrhebels im Bereich der Überdeckung bewirkt einen besonders sicheren Halt gegen beidseitiges Verschwenken und vermeidet so unplanmäßiges Lösen der Sperreinrichtung sowie mögliche Beschädigungen des Gesperres.In one embodiment, a recess of the locking contour is adapted to the projection of the locking lever in the locking position, which is defined by the recess. In particular, this adjustment takes place in the overlapping area. Preferably, such an adjustment includes the slopes of the slopes of the projection of the locking lever with a. The adaptation of the contour of a recess of the locking contour to the contour of the projection of the locking lever in the region of the overlap causes a particularly secure hold against bilateral pivoting and thus avoids unscheduled release of the locking device and possible damage to the locking mechanism.

In einer Ausführungsform umfasst der Anschlag eine Schräge der Sperrkontur, die im Wesentlichen parallel zur Schräge des Vorsprungs des Sperrhebels in sperrender Stellung ist, die bei Sperren des Gesperres durch die Sperreinrichtung mit dem Anschlag in Kontakt kommen kann. Durch die im Wesentlichen parallel ausgeformten Schrägen können durch die flächige Kraftaufnahme der Anschlag und der Vorsprung kleiner dimensioniert werden.In one embodiment, the stop comprises a slope of the locking contour, which is substantially parallel to the slope of the projection of the locking lever in the locking position, which can come in case of locking of the locking mechanism by the locking means with the stop in contact. Due to the substantially parallel shaped bevels can be made smaller by the flat power receiving the stop and the projection.

In einer Ausführungsform ist die Achse des Sperrhebels an dem Vorsprung gegenüberliegendem Ende des Sperrhebels angeordnet. Durch die Anordnung der Achse in vorzugsweise größtmöglichen Abstand zum Vorsprung kann ein besonders großer Schwenkweg des Vorsprungs des Sperrhebels bei Betätigung durch Hebelarm des Auslösehebels realisiert werden und dank der damit erzielten Überdeckung des Vorsprungs in der Sperrkontur ein besonders sicherer Halt der Sperreinrichtung in sperrender Stellung bewirkt werden.In one embodiment, the axis of the locking lever is disposed on the projection opposite end of the locking lever. Due to the arrangement of the axis in preferably the greatest possible distance from the projection, a particularly large pivoting of the projection of the locking lever when actuated by the lever arm of the release lever can be realized and thanks to the thus obtained overlap of the projection in the locking contour a particularly secure hold of the locking device are effected in the blocking position ,

Nachfolgend wird die Erfindung anhand von Figuren 1 bis 4 näher erläutert.The invention is based on FIGS. 1 to 4 explained in more detail.

Die Figur 1 zeigt einen insbesondere aus Metall bestehenden Schlosskasten 1 eines Schlosses, der der Lagerung eines Gesperres dient. Das Gesperre umfasst eine drehbar gelagerte, vorzugsweise überwiegend aus Metall bestehende Drehfalle 2, die um ihre Achse 3 herum gedreht werden kann. Das Gesperre umfasst darüber hinaus und eine vorzugsweise überwiegend aus Metall bestehende Hauptrastsperrklinke 4 und eine vorzugsweise überwiegend aus Metall bestehende Vorrastsperrklinke 5.The FIG. 1 shows a particular metal lock case 1 of a castle that serves to support a Gesperres. The ratchet comprises a rotatably mounted, preferably predominantly made of metal rotary latch 2, which can be rotated about its axis 3 around. The locking mechanism also comprises a main latching pawl 4, preferably made predominantly of metal, and a pre-ratchet pawl 5, which is preferably made predominantly of metal.

Die Hauptrastsperrklinke 4 und die Vorrastsperrklinke 5 sind übereinander angeordnet und verfügen über eine gemeinsame Drehachse 6, damit die beiden Sperrklinken 4 und 5 unabhängig voneinander gedreht werden können. Das Gesperre umfasst ferner einen Blockadehebel 7, der wie in der Figur 1 gezeigt die Hauptrastsperrklinke 4 in der dargestellten verrasteten Stellung des Gesperres zu blockieren vermag. Die Drehfalle 2, die Hauptrastsperrklinke 4 und der Blockadehebel 7 befinden sich im Wesentlichen in einer gemeinsamen Ebene. In einer darüber liegenden Ebene befindet sich die Vorrastsperrklinke 5. In Figur 1 wird ein Großteil der Hauptrastsperrklinke 4 durch die Vorrastsperrklinke 5 verdeckt, insbesondere der Teil der Hauptrastsperrklinke 4, welcher die Drehfalle 2 verrastet.The main catch pawl 4 and the Vorrastsperrklinke 5 are arranged one above the other and have a common axis of rotation 6, so that the two pawls 4 and 5 can be rotated independently. The ratchet further comprises a blocking lever 7, as in the FIG. 1 shown the main latch pawl 4 is able to block in the illustrated locked position of the locking mechanism. The catch 2, the main catch pawl 4 and the blocking lever 7 are located substantially in a common plane. In a higher level there is the Vorrastsperrklinke 5. In FIG. 1 a major part of the main catch pawl 4 is covered by the Vorrastsperrklinke 5, in particular the part of the Haupttrastsperrklinke 4, which locks the catch 2.

Um die Drehfalle 2 in der Vorrastposition verrasten zu können, verfügt die Drehfalle 2 über einen vorstehenden Bolzen 8, der gegen den Hebelarm 9 der Vorrastsperrklinke 5 für ein Verrasten in der Vorrastposition bewegt werden kann. Das Ende des Hebelarms 9 verhindert dann ein Drehen der Drehfalle 2 im Uhrzeigersinn in Richtung ihrer geöffneten Stellung.In order to lock the catch 2 in the pre-locking position, the rotary latch 2 has a protruding pin 8 which can be moved against the lever arm 9 of the Vorrastsperrklinke 5 for locking in the pre-locking position. The end of the lever arm 9 then prevents clockwise rotation of the rotary latch 2 in the direction of its open position.

Die Drehfalle 2 vermag ein öffnendes Moment in die Hauptrastsperrklinke 4 einzuleiten. Verlässt der Blockadehebel 7 seine blockierende Position, so bewegt sich die Hauptrastsperrklinke 4 aufgrund des eingeleiteten öffnenden Momentes aus ihrer Rastposition heraus. Die Drehfalle 2 kann dann in ihre geöffnete Stellung bewegt werden und zwar durch Drehen um ihre Achse 3 im Uhrzeigersinn.The rotary latch 2 is able to initiate an opening moment in the main latching pawl 4. If the blocking lever 7 leaves its blocking position, then the main latching pawl 4 moves out of its rest position due to the opening moment introduced. The catch 2 can then moved to its open position by rotating about its axis 3 in a clockwise direction.

Die Vorrastsperrklinke 5 stellt zugleich den Auslösehebel des Schlosses dar. Wird der Auslösehebel 5 im Uhrzeigersinn gedreht und somit betätigt, so erfasst ein Vorsprung 10 der Vorrastsperrklinke 5 einen Mitnehmer 11 des Blockadehebels 7 und dreht so den Blockadehebel 7 aus seiner blockierenden Position heraus, wenn die Vorrastsperrklinke 5 bzw. der Auslösehebel 5 nicht übermäßig stark beschleunigt wird.The Vorrastsperrklinke 5 also represents the release lever of the lock. If the release lever 5 is rotated clockwise and thus actuated, so a projection 10 of the Vorrastsperrklinke 5 detects a driver 11 of the blocking lever 7 and thus turns the blocking lever 7 out of its blocking position when the Vorrastsperrklinke 5 or the trigger lever 5 is not excessively accelerated.

Wird der Auslösehebel 5 für ein Öffnen des Gesperres im Uhrzeigersinn verdreht, so bewegt das Ende eines Hebelarms 12 des Auslösehebels 5 einen Mitnehmer 13 eines in der Figur 1 verdeckten Sperrhebels 21 einer Sperreinrichtung. Der Sperrhebel 21 ist durch eine Achse 14 mit einem Trägheitshebel 15 drehbar verbunden. Unter dem Trägheitshebel 15 ist der Sperrhebel 21 angeordnet. Der Mitnehmer 13 reicht durch ein Langloch 16 des Trägheitshebels 15 hindurch und wird oberhalb des Trägheitshebels 15 vom Hebelarm 12 des Auslösehebels 5 erfasst.If the release lever 5 is rotated clockwise for opening the locking mechanism, the end of a lever arm 12 of the release lever 5 moves a driver 13 in the FIG. 1 concealed locking lever 21 a locking device. The locking lever 21 is rotatably connected by an axle 14 with an inertia lever 15. Under the inertia lever 15, the locking lever 21 is arranged. The driver 13 extends through a slot 16 of the inertia lever 15 and is detected above the inertial lever 15 by the lever arm 12 of the release lever 5.

Wird der Auslösehebel 5 übermäßig stark beschleunigt, so wird der Sperrhebel 21 um seine Achse 14 im Uhrzeigersinn verschwenkt, nicht aber der Trägheitshebel 15 um seine Achse 17. Dies wird unter anderem deshalb ermöglicht, weil der Mitnehmer 13 des Sperrhebels 21 durch das Langloch 16 hineinreicht, welches eine Relativbewegung zwischen dem Sperrhebel 21 und dem Trägheitshebel 15 erlaubt.If the release lever 5 is excessively accelerated, the locking lever 21 is pivoted about its axis 14 in the clockwise direction, but not the inertia lever 15 about its axis 17. This is among other reasons, because the driver 13 of the locking lever 21 extends through the slot 16 which allows a relative movement between the locking lever 21 and the inertia lever 15.

Ein Ende des Sperrhebels 21 gelangt bei übermäßiger Beschleunigung so in eine der sperrenden Stellungen (25, 26, 27), die durch eine starr am Schlosskasten 1 befestigte Sperrkontur 18 bewirkt wird. Hierdurch wird verhindert, dass der Auslösehebel 5 weiter im Uhrzeigersinn für ein Herausbewegen des Blockadehebels 7 aus seiner blockierenden Position verdreht werden kann. Es wird so vermieden, dass der Blockadehebel 7 aus seiner blockierenden Position für ein Öffnen des Gesperres heraus bewegt wird und zwar durch Verdrehen des Blockadehebels 7 um seine Achse 19.One end of the locking lever 21 passes in excessive acceleration so in one of the locking positions (25, 26, 27), which is effected by a rigidly attached to the lock case 1 locking contour 18. This prevents that the release lever 5 can be further rotated clockwise for a move out of the blocking lever 7 from its blocking position. It is thus avoided that the blocking lever 7 from its blocking position for opening the locking out is moved by turning the blocking lever 7 about its axis 19th

Die Sperrkontur 18 umfasst einen Anschlag 25 und die Ausnehmungen 26 und 27, durch welche die sperrenden Stellungen (25, 26, 27) der Sperreinrichtung bzw. des Sperrhebels 21 festgelegt werden.The blocking contour 18 comprises a stop 25 and the recesses 26 and 27, by which the blocking positions (25, 26, 27) of the locking device or the locking lever 21 are fixed.

Der Sperrhebel 21 weist einen dreieckförmigen Vorsprung 28 mit Schrägen an beiden Seiten auf, wobei die entgegen dem Uhrzeigersinn angeordnete Schräge 29 eine geringere Steigung aufweist als die andere, gegenüberliegende Schräge des Vorsprungs, welche in Uhrzeigersinn um die Achse 14 angeordnet ist.The locking lever 21 has a triangular projection 28 with bevels on both sides, wherein the counterclockwise inclined 29 has a smaller pitch than the other, opposite slope of the projection, which is arranged in a clockwise direction about the axis 14.

Der Anschlag 25 ist als eine Schräge der Sperrkontur 18 ausgeformt, die im Wesentlichen parallel zur Schräge 29 des Vorsprungs 28 des Sperrhebels 21 in sperrender Stellung ist. Bei Sperren des Gesperres durch die Sperreinrichtung kann die Schräge 29 in Kontakt mit dem Anschlag 25 kommen.The stop 25 is formed as a slope of the locking contour 18, which is substantially parallel to the slope 29 of the projection 28 of the locking lever 21 in the locking position. When locking the locking mechanism by the locking device, the slope 29 can come into contact with the stop 25.

Die Ausnehmungen 26 und 27 sind dreieckförmig ausgeformt, wobei die Kontur der Ausnehmungen (26 bzw. 27) an den Vorsprung 28 des Sperrhebels 21 in der sperrenden Stellung, die durch die jeweilige Ausnehmung (26 bzw. 27) festgelegt ist, angepasst sind.The recesses 26 and 27 are triangular in shape, wherein the contour of the recesses (26 and 27) to the projection 28 of the locking lever 21 in the locking position, which is determined by the respective recess (26 and 27), adapted.

Der Trägheitshebel 15 umfasst am unteren Ende einen Spalt 20, der dem Verbinden mit einem Schenkel 22 einer Feder 23 dient. Der Schenkel 22 der Feder 23 reicht dann in diesen Spalt 20 hinein.The inertia lever 15 comprises at the lower end a gap 20 which serves to connect to a leg 22 of a spring 23. The leg 22 of the spring 23 then extends into this gap 20.

Die Figuren 2 und 3 verdeutlichen Aufbau und Funktion der Sperreinrichtung im Fall eines üblichen Öffnens des Schlosses.The Figures 2 and 3 clarify the structure and function of the locking device in the case of a conventional opening of the lock.

Die Figur 2 zeigt die Ausgangssituation, wenn das Gesperre verrastet ist. Unterhalb des Trägheitshebels 15 befindet sich der Sperrhebel 21. Ein Schenkel 22 der vorgespannten Feder 23 befindet sich im Spalt 20 und ist so mit dem Trägheitshebel 15 verbunden. Die Feder 23 befindet sich ebenfalls unter dem Trägheitshebel 15 und ist um die Achse 17 herum geführt. Die Achse 17 trägt so zum Halten der Feder 23 bei. Der andere Schenkel 24 der Feder 23 ist mit dem Sperrhebel 21 verbunden. Vorzugsweise liegt der Schenkel 24 an einer seitlichen Kontur, beispielsweise an einem nach unten reichenden Vorsprung des Sperrhebels 21, vorgespannt an.The FIG. 2 shows the initial situation when the locking mechanism is locked. Below the inertia lever 15 is the locking lever 21. A leg 22 of the prestressed spring 23 is located in the gap 20 and is thus connected to the inertia lever 15. The spring 23 is also under the inertia lever 15 and is guided around the axis 17 around. The axis 17 thus contributes to the holding of the spring 23. The other leg 24 of the spring 23 is connected to the locking lever 21. Preferably, the leg 24 is biased on a lateral contour, for example on a downwardly extending projection of the locking lever 21.

Wird der Auslösehebel 5 für ein Öffnen des Gesperres im Uhrzeigersinn um seine Achse 6 gedreht und dabei nicht übermäßig stark beschleunigt, so wirkt die Feder 23 wie eine starre Verbindung zwischen dem Sperrhebel 21 und dem Trägheitshebel 15. Das Drehen des Auslösehebels 5 im Uhrzeigersinn bewirkt dann, dass der Mitnehmer 13 des Sperrhebels 21 nach links bewegt wird. Dadurch dreht sich der Trägheitshebel 15 gemeinsam mit dem Sperrhebel 21 um seine Achse 17 entgegengesetzt zum Uhrzeigersinn. Der Sperrhebel 21 gelangt dann nicht in eine der sperrenden Stellungen (25, 26, 27). Durch Drehen des Auslösehebels 5 im Uhrzeigersinn kann der Blockadehebel 7 aus seiner blockierenden Position heraus bewegt werden. Anschließend öffnet sich das Gesperre.If the release lever 5 is rotated clockwise about its axis 6 for opening the locking mechanism and not accelerated excessively, the spring 23 acts as a rigid connection between the locking lever 21 and the inertia lever 15. Turning the release lever 5 in the clockwise direction then causes in that the driver 13 of the blocking lever 21 is moved to the left. As a result, the inertia lever 15 rotates together with the locking lever 21 about its axis 17 counterclockwise. The locking lever 21 then does not get into one of the blocking positions (25, 26, 27). By turning the release lever 5 clockwise, the blocking lever 7 can be moved out of its blocking position. Then the locking mechanism opens.

Figur 4 zeigt den Fall, wenn der Auslösehebel 5 ausgehend von der in der Figur 2 gezeigten Situation übermäßig stark beschleunigt worden ist. Aufgrund der vergleichsweise großen Masse des Trägheitshebels 15 im Vergleich zum Sperrhebel 21 wird der Trägheitshebel 15 nicht mehr um seine Achse 17 entgegengesetzt zum Uhrzeigersinn verdreht. Stattdessen wird der Schenkel 24 ausgelenkt. Der Sperrhebel 21 wird nun um seine Achse 14 im Uhrzeigersinn verdreht und in seine sperrende Stellung 25 hinein bewegt, die in der Figur 4 gezeigt ist. FIG. 4 shows the case when the release lever 5, starting from in the FIG. 2 situation has been excessively accelerated. Due to the comparatively large mass of the inertia lever 15 in comparison to the locking lever 21, the inertia lever 15 is no longer rotated counterclockwise about its axis 17. Instead, the leg 24 is deflected. The locking lever 21 is now rotated about its axis 14 in a clockwise direction and moved into its blocking position 25, which in the FIG. 4 is shown.

Die sperrende Stellung 25 ist dann erreicht, wenn das Ende 28 des Sperrhebels 21 den Anschlag 25 überdeckt, so dass der Trägheitshebel 15 nicht entgegen dem Uhrzeigersinn gedreht werden kann. Die sperrende Stellung 25 ist also auch dann eingenommen, wenn das Ende 28 des Sperrhebels 21 den Anschlag 25 zwar überdeckt, aber diesen nicht berührt, wie in Figur 4 abgebildet. Die Sperrkontur 18 verhindert nun, dass der Auslösehebel 5 derart weit um seine Achse 6 im Uhrzeigersinn gedreht werden kann, dass dadurch der Blockadehebel 7 aus seiner blockierenden Position heraus bewegt wird.The blocking position 25 is reached when the end 28 of the locking lever 21 covers the stop 25, so that the inertia lever 15 can not be rotated counterclockwise. The blocking position 25 is thus also taken when the end 28 of the locking lever 21, although the stopper 25 covers, but this does not affect, as in FIG. 4 displayed. The blocking contour 18 now prevents the trigger lever 5 can be rotated so far about its axis 6 in the clockwise direction that thereby the blocking lever 7 is moved out of its blocking position.

Im Fall eines Rückpralls kann es vorkommen, dass sich der Sperrhebel 21 aus der sperrenden Stellung 25 am Anschlag 25 der Sperrkontur 18 ungewollt löst. Der Trägheitshebel 15 könnte sich dann entgegen dem Uhrzeigersinn bewegen, so dass der Auslösehebel 5 das Gesperre unplanmäßig öffnet. Die Ausnehmungen 26 und 27, die in Umfangrichtung des Trägheitshebels 15 entgegen dem Uhrzeigersinn angeordnet sind, ermöglichen es nun, durch Aufnehmen und Sperren des Sperrhebels 21 den Trägheitshebel 15 zu Blockieren und dadurch ein unplanmäßiges Öffnen des Gesperres zu vermeiden.In the case of a rebound, it may happen that the locking lever 21 unintentionally releases from the blocking position 25 on the stop 25 of the locking contour 18. The inertia lever 15 could then move in the counterclockwise direction, so that the release lever 5 opens the ratchet unscheduled. The recesses 26 and 27, which are arranged in the circumferential direction of the inertia lever 15 in the counterclockwise direction, now make it possible to block by receiving and locking the locking lever 21, the inertia lever 15 and thereby avoid unplanned opening of the locking mechanism.
