Description

Die Erfindung betrifft einen Kraftfahrzeugtürverschluß mit um einen Drehfallenbolzen drehbarer Drehfalle und um einen Lagerbolzen schwenkbarer Sperrklinkenanordnung,

  • bei dem im geschlossenen Zustand der Kraftfahrzeugtür ein am Türpfosten befestigter Schloßhalter in eine schloßhalterausnehmung der Drehfalle einfaßt,
  • bei dem die Sperrklinkenanordnung im geschlossenen Zustand der Kraftfahrzeugtür mit einer Sperrklinke eine Gegensperrfläche an der Drehfalle in Sperrposition der Sperrklinkenanordnung mit paßflächigem Kontakt hinterfaßt,
  • bei dem die Sperrklinkenanordnung als Hebelgetriebe mit einem lagerbolzenseitigen Hebel, der um den gehäusefesten Lagerbolzen schwenkbar ist, und einem die Sperrfläche tragenden Hebel ausgeführt ist, welche beiden Hebel über ein Sperrklinkengelenk mit zum Lagerbolzen paralleler Gelenkachse, gegeneinander abknickbar, vereinigt sind,
  • bei dem bei einer Öffnungsbewegung der Sperrklinkenanordnung bei geschlossener Kraftfahrzeugtür der die Sperrfläche tragende Hebel gegenüber dem lagorbolzenseitigen Hebel abknickt und ein Sperrstellungsanschlag freikommt sowie ein Abknickanschlag zur Anlage kommt und dadurch der paßflächige Kontakt in einen Linienkontakt überführbar ist. Der Begriff paßflächig bezeichnet einen ausreichend vollständigen Flächenkontakt, der die Flächenpressung Im gesperrten Zustand der Drehfalle reduziert. Bei einem solchen Kraftfahrzeugtürverschluß kann die Sperrklinke über einen Außenbetätigungshebel oder über einen Innenbetätigungshebel derart betätigt werden, daß sie bei geschlossener Kraftfahrzeugtür ihre Sperrposition verlaßt und die Drehfalle einsperrt. Es versteht sich, daß die Sperrfläche und die Gegensperrfläche an der Sperrklinkenanordnung bzw. an der Drehfalle im geschlossenen Zustand der Kraftfahrzeugtür mit einer nicht unbeachtlichen Kraft gegeneinander gedrückt werden. Diese Kraft resultiert aus der Tatsache, daß die Kraftfahrzeugtür im geschlossenen Zustand von der weichelastischen Türdichtung federnd zurückgedrückt wird und über die Drehfalle an dem Schloßhalter eine entsprechende Abstützung erfährt.
The invention relates to a motor vehicle door lock with a rotary latch rotatable about a rotary latch bolt and a pawl arrangement pivotable about a bearing bolt.
  • in which, in the closed state of the motor vehicle door, a lock holder fastened to the door jamb fits into a lock holder recess in the catch,
  • in which the pawl arrangement in the closed state of the motor vehicle door with a pawl engages a counter-blocking surface on the catch in the blocking position of the pawl arrangement with a mating contact,
  • in which the pawl arrangement is designed as a lever mechanism with a lever on the bearing pin side, which can be pivoted about the bearing pin fixed to the housing, and a lever carrying the blocking surface, which two levers are united via a pawl joint with an articulated axis parallel to the bearing pin, which can be bent against one another,
  • in the case of an opening movement of the pawl arrangement with the motor vehicle door closed, the lever bearing the blocking surface bends relative to the lever on the bearing pin and a blocking position stop is released and a kinking stop comes into contact, and as a result the mating surface contact can be converted into a line contact. The term mating surface denotes a sufficiently complete surface contact, which is the surface pressure Reduced when the rotary latch is locked. In such a motor vehicle door lock, the pawl can be actuated via an external actuation lever or an internal actuation lever such that it leaves its locked position when the motor vehicle door is closed and locks the catch. It goes without saying that the locking surface and the counter locking surface on the pawl arrangement or on the rotary latch are pressed against one another with a not inconsiderable force when the motor vehicle door is closed. This force results from the fact that the motor vehicle door is pressed back resiliently by the soft-elastic door seal in the closed state and is appropriately supported via the catch on the lock holder.

Bei einem Kraftfahrzeugtürverschluß der eingangs beschriebenen Gattung (EP-A 0 406 777) ist der lagerbolzenseitige Hebel mit dem die Sperrfläche tragenden Hebel über ein Sperrklinkengelenk verbunden, das von einer sphärisch geformten Nase an dem die Sperrfläche tragenden Hebel gebildet wird, welche in eine passende Gelenkpfanne am lagerbolzenseitigen Hebel einfaßt. Außerdem ist an dem die Sperrfläche tragenden Hebel eine Anschlagnase gebildet, die vom lagerbolzenseitigen Hebel überklammert wird und die bei einer Öffnungsbewegung der Sperrklinkenanordnung vom Sperrstellungsanschlag in den Abknickanschlag des lagerbolzenseitigen Hebels übergeht. Bei einer Öffnungsbewegung der Sperrklinkenanordnung und bei Überführung des paßflächigen Kontakts von Sperrfläche und Gegensperrfläche in einen Linienkontakt haben beide Nasen des die Sperrfläche tragenden Hebels gleitenden Kontakt zu dem lagerbolzenseitigen Hebel. Dadurch ist eine Gleitreibung zu überwinden, die eine verhältnismäßig große Kraft für die Betätigung der Sperrklinke bis zur Entsperrung der Drehfalle erfordert. Bei einer anderen Ausführung (FR-A-2 372 299) ist der die Sperrfläche tragende Hebel nicht nur über eine Stift-Schlitz-Verbindung geführt, sondern steht außerdem noch unter der Wirkung einer Feder. Auch dafür gelten die oben erläuterten Nachteile.In a motor vehicle door lock of the type described in the introduction (EP-A 0 406 777), the lever on the bearing pin side is connected to the lever carrying the locking surface by means of a pawl joint which is formed by a spherically shaped nose on the lever carrying the locking surface, which in a suitable joint socket on the bearing pin-side lever. In addition, a stop lug is formed on the lever carrying the locking surface, which is clamped over by the lever on the bearing pin side and which, when the pawl arrangement opens, moves from the locking position stop into the kinking stop of the lever on the bearing pin side. During an opening movement of the pawl arrangement and when the mating surface contact of the locking surface and counter locking surface is in line contact, both lugs of the lever carrying the locking surface have sliding contact with the lever on the bearing pin side. This is a sliding friction to overcome, which requires a relatively large force for the actuation of the pawl until the catch is unlocked. In another embodiment (FR-A-2 372 299) the lever carrying the locking surface is not only guided via a pin-slot connection, but is also still under the action of a spring. The disadvantages explained above also apply to this.

Der Erfindung liegt die Aufgabe zugrunde, einen Kraftfahrzeugtürverschluß zu schaffen, bei dem bei einer Öffnungsbewegung der Kraftfahrzeugtür die Sperrklinkenanordnung sehr leicht bewegbar ist.The invention has for its object to provide a motor vehicle door lock in which the pawl arrangement is very easy to move when the motor vehicle door is opened.

Diese Aufgabe wird dadurch gelöst, daß das Sperrklinkengelenk als Bolzengelenk ausgeführt ist und
daß der die Sperrfläche tragende Hebel mit Abstand von der Sperrfläche eine Lagerbolzenaufnahme für den Lagerbolzen aufweist, die den Sperrstellungsanschlag, und mit schaltspielabstand den Abknickanschlag aufweist, und
daß beim Öffnen der Sperrklinkenanordnung der Sperrstellungsanschlag von dem Lagerbolzen freikommt, sowie der Abknickanschlag an dem Lagerbolzen zur Anlage kommt.This object is achieved in that the pawl joint is designed as a pin joint and
that the locking surface bearing lever at a distance from the locking surface has a bearing pin receptacle for the bearing pin, which has the locking position stop, and the switching stop with the switching stop, and
that when the pawl arrangement is opened, the locking position stop is released from the bearing pin, and the bend stop comes to rest on the bearing pin.

Erfindungsgemäß wird bei der Öffnung der Kraftfahrzeugtür die Entsperrung der Drehfalle durch ein Abknicken der Sperrklinkenanordnung eingeleitet. Es versteht sich, daß das Hebelgetriebe, welches die Sperrklinkenanordnung bildet, in der Sperrstellung stark, aber bei entsperrender Betätigung der Sperrklinkenanordnung leicht abknickbar ist. Das kann auf verschiedene Weise verwirklicht werden, Eine bevorzugte Ausführungsform, bei der die Sperrklinkenanordnung in Sperrstellung eine Zugbelastung erführt ist in diesem Zusammenhang dadurch gekennzeichnet, daß der die Sperrfläche tragende Hebel als zweiarmiger Hebel ausgeführt ist, bei dem ein Hebelarm die Sperrfläche und der gegenüberliegende Hebelarm jenseits des Bolzengelenks die Lagerbolzenaufnahme aufweist, und daß der Hebelarm mit der Sperrfläche des die Sperrfläche tragenden Hebels und der lagerbolzenseitige Hebel hintereinander angeordnet sind, und daß die Lagerbolzenaufnahme am gegenüberliegenden Hebelarm des die Sperrfläche tragenden Hebels als Gabel ausgebildet ist, die den Lagerbolzen umfaßt und das Schaltspiel definiert, und daß In der Sperrstellung bei paßflächigem Kontakt von Sperrfläche und Gegensperrfläche die in der Ebene der Sperrklinkenanordnung verlaufende Verbindungslinie zwischen der Achse des Lagerbolzens, der Achse des Bolzengelenkes und der Kontaktlinie des mit dem Beginn der Abknickung sich einstellenden Linienkontaktes in einer Geraden verläuft.According to the invention, when the motor vehicle door is opened, the catch is unlocked by kinking the pawl arrangement. It is understood that the lever mechanism, which forms the pawl arrangement, in the locked position strong, but can be easily bent when the pawl arrangement is unlocked. This can be achieved in various ways. A preferred embodiment in which the pawl arrangement carries a tensile load in the locking position is characterized in this context in that the lever carrying the locking surface is designed as a two-armed lever, in which one lever arm the locking surface and the opposite lever arm beyond the pin joint, the bearing pin receptacle, and that the lever arm with the locking surface of the lever carrying the locking surface and the bearing pin-side lever are arranged one behind the other, and that the bearing pin receptacle on the opposite lever arm of the lever carrying the locking surface is designed as a fork, which includes the bearing pin and that Switching game defined, and that in the locking position with a mating surface contact of the locking surface and counter locking surface, the connecting line running in the plane of the pawl arrangement between the axis of the bearing pin, the axis of the pin joint and the contact line of the line contact which occurs at the beginning of the bend runs in a straight line.

Eine andere Ausführungsform, bei der die Sperrklinkenanordnung in der Sperrstellung eine Druckbelastung erfährt, ist in diesem Zusammenhang dadurch gekennzeichnet, daß der die Sperrfläche tragende Hebel als einarmiger Hebel ausgeführt ist, der an einem Ende die Sperrfläche sowie am anderen Ende das Bolzengelenk aufweist, und daß im Bereich zwischen Sperrfläche und Bolzengelenk die Lagerbolzenaufnahme in Form eines Fensters angeordnet ist, welches das Schaltspiel definiert, und daß der die Sperrfläche tragende Hebel und der lagerbolzenseitige Hebel übereinander angeordnet sind, und daß In der Sperrstellung bei paßflächigem Kontakt von Sperrfläche und Gegensperrfläche die in einer Ebene parallel zur Sperrklinkenanordnung verlaufende Verbindungslinie zwischen der Achse des Lagerbolzens, der Achse des Bolzengelenkes und der Kontaktlinie des mit dem Beginn der Abknickung sich einstellenden Linienkontaktes in einer Geraden verläuft, In allen Fällen ist es zweckmäßig, daß die Sperrklinkenanordnung eine Rückstellfederanordnung aufweist, die der Ausknickung entgegenwirkt,Another embodiment in which the pawl arrangement is subjected to a pressure load in the locking position is characterized in this context in that the lever carrying the locking surface is designed as a one-armed lever which has the locking surface at one end and the pin joint at the other end, and in that in the area between the locking surface and the pin joint, the bearing pin receptacle is arranged in the form of a window which defines the switching game, and that the lever carrying the locking surface and the lever on the bearing pin side are superimposed are arranged, and that in the locking position with a mating surface contact of the locking surface and counter locking surface, the connecting line running in a plane parallel to the pawl arrangement between the axis of the bearing pin, the axis of the pin joint and the contact line of the line contact which occurs at the beginning of the bend runs in a straight line In all cases, it is expedient for the pawl arrangement to have a return spring arrangement which counteracts the buckling.

Die Erfindung geht von der Erkenntnis aus, daß bei der Öffnungsbewegung der Sperrklinkenanordnung eine mit der Abknickung eine rollende Reibung zwischen der Sperrfläche und der Gegensperrfläche eingeleitet oder superponiert werden kann, wenn die bei der bekannten Ausführungsform einteilige und starre Sperrklinke durch ein Hebelgetriebe In der beschriebenen Art und Weise ersetzt wird. Die rollende Reibung reduziert erheblich die Kraft, die für die Einleitung der Öffnungsbewegung der Sperrklinke erforderlich ist. Im Anschluß an diese Einleitung der Öffnungsbewegung der Sperrklinkenanordnung kann die weitere Öffnung bis zur Entsperrung der Drehfalle mit überraschend geringer Kraft fortgesetzt werden, weil die Abknickung zwischen dem lagerbolzenseitigen Hebel und dem die Sperrfläche tragenden Hebel bei Fortsetzung der Öffnungsbewegung der Sperrklinkenanordnung größer wird, der Winkel der Abknickung also kleiner wird.The invention is based on the knowledge that during the opening movement of the pawl arrangement, a rolling friction between the locking surface and the counter-locking surface can be initiated or superposed when the kink, if the one-piece and rigid pawl in the known embodiment is operated by a lever mechanism in the manner described and way is replaced. The rolling friction significantly reduces the force required to initiate the pawl opening movement. Following this initiation of the opening movement of the pawl arrangement, the further opening can be continued with surprisingly little force until the catch is unlocked because the kink between the lever on the bearing pin side and the lever carrying the locking surface increases as the opening movement of the pawl arrangement continues, the angle of Kink becomes smaller.

In the following, the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. They show a schematic representation

Der in den Figuren dargestellte Kraftfahrzeugtürverschluß 1 besitzt eine um einen Drehfallenbolzen 2 drehbare Drehfalle 3 und eine um einen Lagerbolzen 4 schwenkbare Sperrklinkenanordnung 5, 6. Im geschlossenen Zustand der Kraftfahrzeugtür faßt ein am nicht gezeichneten Türpfosten des Kraftfahrzeuges befestigter Schloßhalter 7 in eine Schloßhalterausnehmung der Drehfalle 3 ein, wie es in den Figuren dargestellt ist. Man erkennt in den Fig. 1, 2 und 4, daß die Sperrklinkenanordnung 5, 6 im geschlossenen Zustand der Kraftfahrzeugtür mit einer Sperrfläche 8 eine Gegensperrfläche 9 an der Drehfalle 3 in Sperrposition der Sperrklinkenanordnung 5, 6 mit paßflächigem Kontakt hinterfaßt.The motor vehicle door lock 1 shown in the figures has a rotary latch 3 which can be rotated about a pivot bolt 2 and a pawl arrangement 5, 6 which can be pivoted about a bearing bolt 4. In the closed state of the motor vehicle door, a lock holder 7 fastened to the door post of the motor vehicle (not shown) fits into a lock holder recess in the rotary latch 3 one as shown in the figures. 1, 2 and 4 that the pawl arrangement 5, 6 in the closed state of the motor vehicle door with a blocking surface 8 engages a counter-blocking surface 9 on the catch 3 in the blocking position of the pawl arrangement 5, 6 with a mating surface contact.

Bei dem dargestellten Kraftfahrzeugtürverschluß 1 ist die Sperrklinkenanordnung 5, 6 als Hebelgetriebe mit einem lagerbolzenseitigen Hebel 5, der um den Lagerbolzen 4 schwenkbar ist, und einem die Sperrfläche 8 tragenden Hebel 6 ausgeführt. Die beiden Hebel 5, 6 sind über ein Sperrklinkengelenk 10 mit zum Lagerbolzen 4 paralleler Gelenkachse gegeneinander abknickbar, vereinigt. Der die Sperrfläche 8 tragende Hebel 6 ist ein zweiarmiger Hebel und besitzt einen Sperrflächenhebelarm 11 sowie einen lagerbolzenseitigen Hebelarm 12. An den lagerbolzenseitigen Hebelarm 12 ist eine Lagerbolzenaufnahme 13 mit Schaltspiel zwischen einem Sperrstellungsanschlag 14 und einem Abknickanschlag 15 verwirklicht.In the motor vehicle door lock 1 shown, the pawl arrangement 5, 6 is a lever mechanism with a bearing pin-side lever 5, which can be pivoted about the bearing pin 4, and one the blocking surface 8 supporting lever 6 executed. The two levers 5, 6 can be bent against one another via a pawl joint 10 with a joint axis parallel to the bearing pin 4. The lever 6 supporting the locking surface 8 is a two-armed lever and has a locking surface lever arm 11 and a lever arm 12 on the bearing pin side.

Die Sperrklinkenanordnung 5, 6 kann über die sogenannte Außenbetätigung oder die sogenannte Innenbetätigung betätigt werden. Aus einer vergleichenden Betrachtung der Fig. 2 und 3 entnimmt man, daß bei einer Öffnungsbewegung der Sperrklinkenanordnung 5, 6 bei geschlossener Kraftfahrzeugtür der die Sperrfläche 8 tragende Hebel 6 gegenüber dem bolzenseitigen Hebel 5 abknickt und der Sperrstellungsanschlag 14 der Lagerbolzenaufnahme 13 von dem Lagerbolzen 4 freikommt sowie der Abknickanschlag 15 an dem Lagerbolzen 4 zur Anlage kommt. Das geschieht mehr oder weniger sprungartig. Auf diese Weise wird der paßflächige Kontakt, den man in den Fig. 1, 2 und 4 zwischen der Sperrfläche 8 und der Gegensperrfläche 9 erkennt, in einen Linienkontakt 16 überführt. Dieser ist in Fig. 3 erkennbar. Der Linienkontakt, der mit dem Beginn des Ausknickens der Sperrklinkenanordnung 5, 6 entsteht, wurde auch in den Fig. 1, 2 und 4 mit 16 angedeutet.The pawl arrangement 5, 6 can be actuated via the so-called external actuation or the so-called internal actuation. From a comparative view of FIGS. 2 and 3 it can be seen that when the pawl arrangement 5, 6 is opened when the motor vehicle door is closed, the lever 6 carrying the locking surface 8 bends relative to the lever 5 on the bolt side and the blocking position stop 14 of the bearing pin receptacle 13 is released from the bearing bolt 4 and the bend stop 15 comes to rest on the bearing pin 4. This happens more or less suddenly. In this way, the mating surface contact, which can be seen in FIGS. 1, 2 and 4 between the blocking surface 8 and the counter-blocking surface 9, is converted into a line contact 16. This can be seen in Fig. 3. The line contact which arises when the pawl arrangement 5, 6 begins to buckle has also been indicated at 16 in FIGS. 1, 2 and 4.

Bei den Fig. 1 bis 3 handelt es sich um die Ausführungsform, bei der die Sperrklinkenanordnung 5, 6 in Sperrstellung eine Zugbelastung erfährt. In der Fig. 2 erkennt man deutlich, daß der lagerbolzenseitige Hebel 5 und der die Sperrfläche 8 tragende Hebel 6 mit seinem Sperrklinkenhebelarm 11 hintereinander angeordnet sind, daß der lagerbolzenseitige Hebelarm 12, des die Sperrfläche 8 tragenden Hebels 6 mit einer Gabel, die die Lagerbolzenaufnahme 13 bildet und das Schaltspiel definiert, umfaßt. Man erkennt in den Fig. 1 und 2, daß in der Sperrstellung die in der Ebene der Sperrklinkenanordnung 5, 6 verlaufende Verbindungslinie 17 zwischen der Achse des Lagerbolzens 4, der Achse des Sperrklinkengelenkes 10 und der Kontaktlinie des Linienkontaktes 16 in einer Geraden verläuft. Die Sperrfläche 8 und die Gegensperrfläche 9 liegen in dieser Sperrstellung noch paßflächig gegeneinander. Die Verhältnisse zu Beginn der Abknickbewegung zeigt die Fig. 3.1 to 3 is the embodiment in which the pawl arrangement 5, 6 experiences a tensile load in the locked position. In Fig. 2 you can clearly see that the bearing pin-side lever 5 and the locking surface 8 carrying lever 6 with his Pawl lever arm 11 are arranged one behind the other that the bearing arm-side lever arm 12, of the lever 6 carrying the locking surface 8 with a fork, which forms the bearing pin receptacle 13 and defines the switching play. 1 and 2 that in the locking position the connecting line 17 extending in the plane of the pawl arrangement 5, 6 runs between the axis of the bearing pin 4, the axis of the pawl joint 10 and the contact line of the line contact 16 in a straight line. The locking surface 8 and the counter locking surface 9 are still in this locking position with a mating surface. 3 shows the conditions at the beginning of the bending movement.

Die Fig. 4 zeigt eine andere Ausführungsform, bei der die Sperrklinkenanordnung 5, 6 in der Sperrstellung eine Druckbelastung erfährt. Hier sind der lagenbolzenseitige Hebel 5 und der die Sperrfläche 8 tragende Hebel 6 übereinander angeordnet. Der Lagerbolzen 4 durchfaßt eine Ausnehmung in dem die Sperrfläche 8 tragenden Hebel 6, die die Lagerbolzenaufnahme 13 darstellt und das Schaltspiel definiert. Auch hier ist die Anordnung so getroffen, daß in dieser Sperrstellung die parallel zur Ebene der Sperrklinkenanordnung 5, 6 verlaufende Verbindungslinie 17 zwischen der Achse des Lagerbolzens 4, der Achse des Sperrklinkengelenkes 10 und der Kontaktlinie des Linienkontaktes 16 in einer Geraden verläuft.FIG. 4 shows another embodiment in which the pawl arrangement 5, 6 experiences a pressure load in the locked position. Here the peg-side lever 5 and the lever 6 carrying the locking surface 8 are arranged one above the other. The bearing pin 4 includes a recess in the lever 6 carrying the locking surface 8, which represents the bearing pin receptacle 13 and defines the switching game. Again, the arrangement is such that in this locking position, the connecting line 17 running parallel to the level of the pawl arrangement 5, 6 runs between the axis of the bearing pin 4, the axis of the pawl joint 10 and the contact line of the line contact 16 in a straight line.

In den Fig. 2 und 3 erkennt man zunächst die Kraft 18, die über die Abstützung der geschlossenen Kraftfahrzeugtür an dem Schloßhalter 7 auf die Drehfalle 3 ausgeübt wird. Man erkennt außerdem die Kraft 19, die von der Gegensperrfläche 9 an der Drehfalle 3 auf die Sperrfläche 8 an der Sperrklinkenanordnung 5, 6 in Sperrposition der Sperrklinkenanordnung 5, 6 ausgeübt wird. Die Lage des Sperrklinkengelenkes 10 ist so gewählt, daß die Achse des Sperrklinkengelenkes 10 auf der Wirklinie dieser letztgenannten Kraft liegt. Aus der Fig. 2 entnimmt man, daß diese Kraft dafür sorgt, daß sich die dargestellte Sperrklinkenanordnung 5, 6 selbsttätig immer in die gestreckte Lage ausrichtet. Das gilt entsprechend für die Ausführungsform nach Fig. 4.2 and 3, one can first see the force 18 which is exerted on the rotary latch 3 via the support of the closed motor vehicle door on the lock holder 7. One can also see the force 19, which from the counter-blocking surface 9 on the catch 3 to the blocking surface 8 on the pawl arrangement 5, 6 in the locked position Pawl assembly 5, 6 is exercised. The position of the pawl joint 10 is selected so that the axis of the pawl joint 10 lies on the line of action of this latter force. From Fig. 2 it can be seen that this force ensures that the pawl arrangement 5, 6 shown is always automatically aligned in the extended position. This applies correspondingly to the embodiment according to FIG. 4.

In der Fig. 1 erkennt man die Rückstellfederanordnung 20, die der Ausknickung der Sperrklinkenanordnung 5, 6 entgegenwirkt.1 shows the return spring arrangement 20 which counteracts the buckling of the pawl arrangement 5, 6.
