Description
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss mit einem auf einer Schlossplatte gelagertem Gesperre, das eine auf einer Drehachse gelagerte Drehfalle und mindestens eine auch auf einer Drehachse gelagerte Sperrklinke zum Verrasten der Drehfalle umfasst, wobei die Schlossplatte über darin angeordnete Öffnungen an einer Tür des Kraftfahrzeuges befestigt wird.The invention relates to a motor vehicle door lock with a lock mounted on a lock plate, which comprises a rotary latch mounted on a rotation axis and at least one pawl mounted on a rotation axis for latching the catch, the lock plate being fastened to a door of the motor vehicle via openings arranged therein.
Im Rahmen der Erfindung sind mit Tür eines Kraftfahrzeugs sowohl über Scharniere schwenkbare Türen als auch über Schienen verfahrbare, so genannte Schiebetüren gemeint. Die Erfindung umfasst aber auch neben Türen bei Fahrzeugen übliche Heck- und Kofferklappen sowie Motorhauben.In the context of the invention, the door of a motor vehicle means doors which can be swiveled by means of hinges as well as rails which can be moved by means of rails, so-called sliding doors. However, the invention also includes in addition to doors in vehicles usual rear and boot flaps and hoods.
Ein Kraftfahrzeugschloss, vereinfacht auch Schloss für ein Kraftfahrzeug genannt, umfasst ein Gesperre mit einer auf einer Drehachse drehbar gelagerten Drehfalle für die Aufnahme eines an dem Fahrzeug-Karosseriekörper angeordneten Schlosshalters, der häufig auch Schließbolzen oder Schlossbügel genannt wird. Das Gesperre weist weiter mindestens eine ebenfalls auf einer Drehachse drehbar gelagerte Sperrklinke auf, über die die Drehfalle für ein Halten des eingefahrenen Schlosshalters verrastet wird.A motor vehicle lock, also referred to simply as a lock for a motor vehicle, comprises a locking mechanism with a rotary latch rotatably mounted on a rotation axis for receiving a lock holder arranged on the vehicle body body, which is often also called a locking bolt or lock bracket. The locking mechanism also has at least one pawl which is likewise rotatably mounted on an axis of rotation and by way of which the catch is latched for holding the retracted lock holder.
Zum Einfahren des Schlosshalters in die Drehfalle eines Kraftfahrzeugtürschlosses verfügt die Drehfalle über einen durch einen Lastarm und einen Fangarm gebildeten Schlosshalter-Einlaufbereich. In den Einlaufbereich gelangt der Schlosshalter, wenn die entsprechende Tür des Fahrzeuges geschlossen wird. Dabei wird die Drehfalle nach dem Aufprall des Schlosshalters auf den Fangarm von der Öffnungsstellung in die Schließstellung verdreht und dort über die Sperrklinke verrastet. Diese Position wird Hauptrastposition genannt. In dieser Position erfolgt der Kraftübertrag von der Tür auf die Karosserie durch eine Kraftübertragung von der Drehfalle auf den Schließbolzen und zwar über den Lastarm der Drehfalle.For retracting the lock holder into the catch of a motor vehicle door lock, the rotary latch has a lock holder inlet area formed by a load arm and a catching arm. The lock holder enters the inlet area when the corresponding door of the vehicle is closed. The catch is rotated after the impact of the lock holder on the tentacle from the open position to the closed position and locked there over the pawl. This position is called the main detent position. In this position, the power is transmitted from the door to the body by a power transmission from the rotary latch to the locking pin and indeed via the load arm of the rotary latch.
Bei einem Unfall, beziehungsweise einer Fahrzeugkollision, nachfolgend auch als so genannter Crash-Fall bezeichnet, treten meist schlagartig sehr hohe Kräfte, insbesondere Beschleunigungskräfte auf, welche ein mehrfaches der Erdbeschleunigung betragen können. Dadurch ist ein entsprechendes Schloss einschließlich dem Gesperre und der zugehörigen Hebelwerke erheblichen Massenkräften ausgesetzt, welche zu einem ungewollten Öffnen des Gesperres und folglich einem Öffnen des Gesperres führen kann.In an accident, or a vehicle collision, hereinafter also referred to as a so-called crash case, usually occur very suddenly very high forces, especially acceleration forces, which may be a multiple of the acceleration due to gravity. As a result, a corresponding lock including the locking mechanism and the associated lever mechanisms is exposed to considerable inertial forces, which can lead to an unwanted opening of the locking mechanism and consequently to an opening of the locking mechanism.
In der Vergangenheit sind bereits umfangreiche Maßnahmen ergriffen worden, die beim Auftreten abnormaler Beschleunigungskräfte, d. h. im Crash-Fall, eine Schlossbetätigung oder eine Gesperre-Öffnung unterbinden.In the past, extensive measures have already been taken to prevent the occurrence of abnormal acceleration forces, i. H. in the event of a crash, prevent a lock operation or a locking mechanism opening.
So ist es aus der Druckschrift
Bei einem Crash-Fall kann auf die beim Aufprall übermäßigen starken Beschleunigungskräfte ein Rückprall erfolgen, der in Fachkreisen auch Bouncen genannt wird. Durch einen verzögerten und wiederholten Rückprall, insbesondere verbunden mit Änderungen der Beschleunigungskräfte und -richtungen, kann es bei sehr hohen Beschleunigungskräften auch zu einem Versagen des Gesperres kommen, durch das eigentlich ein unplanmäßiges Öffnen im Crash-Fall vermieden werden soll.In the event of a crash, a rebound can occur on the excessive acceleration forces that are excessive on impact, which is also called bouncing in professional circles. By a delayed and repeated rebound, in particular associated with changes in the acceleration forces and directions, it can also come at very high acceleration forces to a failure of the locking mechanism, which should actually avoid an unplanned opening in the event of a crash.
In diesem Zusammenhang kommt der Schlossbefestigung an dem Fahrzeug-Karosseriekörper eine erhöhte Bedeutung zu, insbesondere der Schlossbefestigung im Zusammenhang mit der Lagerung des Gesperres aus Sperrklinke und Drehfalle.In this context, the lock attachment to the vehicle body body is of increased importance, in particular the lock attachment in connection with the storage of the locking pawl and rotary latch.
Kraftfahrzeugschlösser sind in der Regel über die das Gesperre lagernde Schlossplatte aus Metall über Befestigungsöffnungen mit Gewindeeinschnitt mit der jeweiligen Tür durch Verschrauben verbunden. In der Regel sind Schlösser, je nach Anschlagseite der Tür, an einer Türstirnseite angebracht.Motor vehicle locks are usually connected via the lock plate overlapping metal lock plate via mounting openings with threaded recess with the respective door by screwing. As a rule, locks, depending on the stop side of the door, attached to a door front.
