Description

Die Erfindung betrifft einen Türfeststeller für Kraftfahrzeuge, mit einem mit der einen von Kraftfahrzeugtür oder Kraftfahrzeugkarosserie verbindbaren Rastelement und einer mit der anderen von Kraftfahrzeugtür oder Kraftfahrzeugkarosserie verbindbaren, relativ gegenüber dem Rastelement verstellbaren und an dem Rastelement anliegenden Rastfläche.The invention relates to a door lock for motor vehicles, with a connectable to the one of motor vehicle door or vehicle body locking element and connectable to the other of motor vehicle door or motor vehicle body, relative to the locking element adjustable and applied to the locking element locking surface.

Türfeststeller der eingangs genannten Art sind aus dem Stand der Technik in vielfältigen Ausgestaltungen bekannt. Sie dienen dazu, eine Kraftfahrzeugtür in durch die Ausgestaltung des Türfeststellers festgelegten Öffnungswinkeln der Kraftfahrzeugtür gegenüber der Kraftfahrzeugkarosserie gegen ein ungewolltes Weiterschwenken zu arretieren. Die Türfeststeller weisen dabei ein Rastelement auf, welches an einer relativ gegenüber den Rastelementen verstellbaren Rastfläche anliegt, sodass das Rastelement die Rastfläche in Abhängigkeit von den an der Rastfläche angeordneten Rastmarken arretiert. Aufgrund der Wirkverbindung des Rastelements mit der Kraftfahrzeugtür oder Kraftfahrzeugkarosserie und der Verbindung der Rastfläche mit der anderen von Kraftfahrzeugtür oder Kraftfahrzeugkarosserie erfolgt somit über das Zusammenwirken von Rastelement und Rastfläche eine Arretierung der Kraftfahrzeugtür.Door retainers of the type mentioned are known from the prior art in a variety of configurations. They serve to lock a motor vehicle door in defined by the configuration of the door arrester opening angles of the motor vehicle door relative to the vehicle body against unwanted further pivoting. In this case, the door retainers have a latching element which abuts against a latching surface which is adjustable relative to the latching elements, so that the latching element locks the latching surface as a function of the latching marks arranged on the latching surface. Due to the operative connection of the latching element with the motor vehicle door or motor vehicle body and the connection of the latching surface with the other of the motor vehicle door or motor vehicle body, a locking of the motor vehicle door thus takes place via the interaction of latching element and latching surface.

Der Türfeststeller kann als integraler Bestandteil eines Kraftfahrzeugtürscharniers ausgebildet sein, welches zur gelenkigen Anordnung der Kraftfahrzeugtür an der Kraftfahrzeugkarosserie dient. Alternativ kann der Türfeststeller jedoch auch als separates Bauteil ausgeführt sein, welches allein der Arretierung der Kraftfahrzeugtür in vorbestimmten Öffnungswinkeln dient. Sowohl der integrierte Türfeststeller wie auch der separate Türfeststeller haben gemein, dass eine Relativbewegung der Rastfläche gegenüber dem Rastelement in Abhängigkeit von der Schwenkbewegung der Tür gegenüber der Kraftfahrzeugkarosserie erfolgt, sodass über die Anordnung von Rastmarken an der Rastfläche die Öffnungswinkel bestimmt werden können, in denen eine Arretierung der Kraftfahrzeugtür gegenüber der Kraftfahrzeugkarosserie erfolgt.The door arrester may be formed as an integral part of a motor vehicle door hinge, which serves for the articulated arrangement of the motor vehicle door on the motor vehicle body. Alternatively, however, the door lock may also be designed as a separate component, which alone serves to lock the motor vehicle door in predetermined opening angles. Both the integrated door lock as well as the separate door lock have in common that a relative movement of the locking surface relative to the locking element in response to the pivoting movement of the door relative to the vehicle body, so that the opening angle can be determined by the arrangement of locking marks on the locking surface, in which a Locking the motor vehicle door relative to the vehicle body is done.

Bekannte Türfeststeller der eingangs genannten Art weisen jedoch den Nachteil auf, dass es mit zunehmender Betriebsdauer eines mit dem Türfeststeller ausgestatten Kraftfahrzeugs zu einer Geräuschbelästigung bei einer Betätigung der Kraftfahrzeugtür kommen kann, welche aus einer mangelnden Schmierung zwischen Rastelement und Rastfläche resultiert. Diese kann darüber hinaus dazu führen, dass die Betätigung der Kraftfahrzeugtür erschwert wird und es unter Umständen sogar zu einer Beschädigung des Türfeststellers kommt.However, known door retainers of the type mentioned have the disadvantage that it can come with increasing operating time of a fitted with the door lock motor vehicle to a noise nuisance at an actuation of the vehicle door, resulting from a lack of lubrication between locking element and locking surface. This can also cause the operation of the vehicle door is made difficult and it may even lead to damage of the door arrester.

Der Erfindung liegt die Aufgabe zugrunde, einen Türfeststeller bereitzustellen, der eine hohe Zuverlässigkeit aufweist.The invention has for its object to provide a door lock, which has a high reliability.

Die Erfindung löst die Aufgabe durch einen Türfeststeller mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The invention solves the problem by a door arrester having the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Kennzeichnend für den erfindungsgemäßen Türfeststeller ist, dass das Rastelement im Bereich seiner Kontaktfläche mit der Rastfläche eine in die Kontaktfläche eingelassene Vertiefung aufweist. Die Anordnung einer Vertiefung in dem Bereich des Rastelements, in dem dieses in Kontakt mit der Rastfläche steht, erlaubt es, die Vertiefungen zur Anordnung eines Schmiermitteldepots zu verwenden, wodurch eine dauerhafte und gleichbleibende Funktionsweise des Türfeststellers gewährleistet wird. Über die grundsätzlich freie Ausgestaltung der Vertiefung lässt sich dabei die Größe des Schmiermitteldepots sowie die bei der Betätigung stattfindende Verteilung bestimmen, wodurch zuverlässige Aussagen über die Betriebsdauer des Türfeststellers gemacht werden können. Die Vertiefungen lassen sich dabei in einfacher Weise in die Rastelemente einbringen, sodass der erfindungsgemäße Türfeststeller besonders einfach und kostengünstig herstellbar ist.Characteristic of the door lock according to the invention is that the latching element in the region of its contact surface with the latching surface has a recessed into the contact surface recess. The arrangement of a recess in the region of the latching element, in which this is in contact with the latching surface, allows to use the wells for the arrangement of a lubricant reservoir, whereby a permanent and consistent operation of the door arrester is ensured. The size of the lubricant reservoir as well as the distribution taking place during the actuation can be determined via the fundamentally free design of the depression, whereby reliable statements can be made about the service life of the door arrester. The recesses can be easily introduced into the locking elements, so that the door lock invention is particularly simple and inexpensive to produce.

Die Ausgestaltung der Vertiefung ist grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Vertiefung als eine die Kontaktfläche kanalisierende Nut ausgebildet ist. Gemäß dieser Ausgestaltung der Erfindung weist die Kontaktfläche eine Nut auf, welche in Abhängigkeit von ihrer Ausgestaltung an den Stirnseiten beispielsweise verschlossen oder als stirnseitig offene Nut ausgebildet sein kann. Die Verwendung einer Nut als Vertiefung zeichnet sich dabei dadurch aus, dass sie die Aufnahme eines großen Schmiermitteldepots ermöglicht, wobei gleichzeitig die Funktion des für Türfeststellers nicht beeinträchtigt wird. Besonders vorteilhafter Weise ist dabei nach einer Weiterbildung der Erfindung vorgesehen, dass die Nut zur Aufnahme und Verteilung des Schmiermittels ausgebildet ist.The design of the recess is basically arbitrary. According to a particularly advantageous embodiment of the invention, however, it is provided that the recess is formed as a channel which channels the contact surface. According to this embodiment of the invention, the contact surface has a groove which, depending on its configuration, can be closed, for example, on the end faces or designed as a groove open on the face side. The use of a groove as a recess is characterized in that it allows the inclusion of a large lubricant depot, at the same time the Function of the door arrester is not affected. Particularly advantageous manner is provided according to a development of the invention that the groove for receiving and distributing the lubricant is formed.

Gemäß dieser Ausgestaltung der Erfindung dient die Nut nicht allein zur Bereitstellung eines Schmiermitteldepots sondern ist darüber hinaus derart ausgebildet, insbesondere angeordnet und ausgerichtet, dass über das Zusammenwirken der Rastfläche mit dem Rastelement eine Verteilung des Schmiermittels während des Betriebs bewirkt wird, welches den zuverlässigen Betrieb des Türfeststellers in ergänzender Weise durch eine gleichmäßige Schmiermittelverteilung gewährleistet.According to this embodiment of the invention, the groove is not used solely to provide a lubricant depot but is also designed, in particular arranged and aligned, that over the interaction of the locking surface with the locking element, a distribution of the lubricant is effected during operation, which the reliable operation of the Door arrester ensured in a complementary manner by a uniform lubricant distribution.

Die Ausrichtung der Nuten kann dabei den auftretenden Belastungen entsprechend grundsätzlich frei gewählt werden. So ist beispielsweise eine Ausrichtung der Nut parallel zur Bewegungsrichtung der Rastfläche gegenüber den Rastelementen oder aber auch eine rechtwinklig zur Bewegungsrichtung ausgerichtete Anordnung der Nuten denkbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass sich die Nut unter einem Winkel von 10° - 60° , bevorzugt von 25° - 45°, besonders bevorzugt 20° - 40°, insbesondere 35° gegenüber der Bewegungsrichtung der Rastfläche relativ zum Rastelement erstreckt.The orientation of the grooves can be chosen according to the loads occurring basically free. Thus, for example, an alignment of the groove parallel to the direction of movement of the latching surface relative to the latching elements or even a right angle to the direction of orientation of the grooves conceivable. According to a particularly advantageous embodiment of the invention, however, it is provided that the groove at an angle of 10 ° - 60 °, preferably from 25 ° - 45 °, more preferably 20 ° - 40 °, in particular 35 ° relative to the direction of movement of the locking surface relative extends to the locking element.

Gemäß dieser Ausgestaltung der Erfindung sind die Nuten relativ zur Bewegungsrichtung der Rastfläche relativ gegenüber den Rastelementen bei einem Verschwenken der mit dem Türfeststeller verbundenen Kraftfahrzeugtür ausgerichtet. Die Nut verläuft dabei unter einem der vorgenannten Winkel zur sich durch die Bewegungsrichtung ergebenden Längsachse. Eine entsprechend geneigte Anordnung der Nut gewährleistet eine besonders gleichmäßige und zuverlässige Schmiermittelverteilung über die gesamte mit dem Rastelement in Kontakt befindliche Rastfläche. Aufgrund der wechselnden Bewegungsrichtung der Rastfläche gegenüber dem Rastelement kann über die entsprechende Ausrichtung der Nuten die Schmiermittelverteilung in einfacher Weise bestimmt werden.According to this embodiment of the invention, the grooves are aligned relative to the direction of movement of the latching surface relative to the latching elements in a pivoting of the motor vehicle door connected to the door arrester. The groove extends at one of the aforementioned angles to the resulting by the direction of movement longitudinal axis. A correspondingly inclined arrangement of the groove ensures a particularly uniform and reliable distribution of lubricant over the entire detent surface in contact with the detent element. Due to the changing direction of movement of the latching surface relative to the latching element, the lubricant distribution can be determined in a simple manner via the corresponding alignment of the grooves.

Grundsätzlich werden die Vorteile des erfindungsgemäßen Türfeststellers bereits durch die Anordnung einer Vertiefung, welche nach einer vorteilhaften Ausgestaltung der Erfindung durch eine Nut gebildet ist, erreicht. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung weist die Kontaktfläche jedoch mindestens zwei Nuten auf, die besonders bevorzugt zueinander geneigt verlaufen. Gemäß dieser Ausgestaltung der Erfindung wird durch mindestens eine weitere Nut das Schmiermitteldepot in ergänzender Weise gesteigert, sowie durch eine geneigte Anordnung der Nuten zueinander die Schmiermittelverteilung in ergänzender Weise verbessert. Die Nuten können dabei parallel zueinander ausgerichtet sein oder aber zueinander geneigt sein, wobei die Neigung gegenüber der Bewegungsrichtung der Rastfläche gegenüber dem Rastelement bei beiden Nuten überstimmend sein kann, oder aber eine abweichende Neigung vorliegt.In principle, the advantages of the door arrester according to the invention are already achieved by the arrangement of a depression, which according to an advantageous embodiment of the invention is formed by a groove. According to a particularly advantageous embodiment of the invention, however, the contact surface has at least two grooves, which are particularly preferably inclined to each other. According to this embodiment of the invention, the lubricant reservoir is increased in a complementary manner by at least one further groove, as well as improved by an inclined arrangement of the grooves to each other, the lubricant distribution in a complementary manner. The grooves can be aligned parallel to each other or be inclined to each other, wherein the inclination relative to the direction of movement of the locking surface relative to the locking element in both grooves can be out of tune, or there is a different inclination.

Wie bereits eingangs dargelegt, kann die Ausgestaltung der Nuten grundsätzlich frei gewählt werden. So können diese beispielsweise endseitig verschlossen sein oder aber derart in die Oberfläche der Rastelemente eingebracht sein, dass diese stirnseitig offen sind. Auch kann eine Ausgestaltung der Nuten vorgesehen sein, bei der sich der Querschnitt der Nut über deren Längserstreckung verändert. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist ferner vorgesehen, dass die Nuten einen U- und/oder V-förmigen Querschnitt aufweisen, durch den zum einen ein hohes Schmiermitteldepot bereitgestellt werden kann, gleichzeitig jedoch auch eine gute Schmiermittelverteilung gewährleistet wird.As already stated at the outset, the configuration of the grooves can basically be chosen freely. Thus, for example, these can be closed at the end or can be introduced into the surface of the latching elements in such a way that they are open on the front side. Also, an embodiment of the grooves may be provided, in which the cross section of the groove changes over its longitudinal extent. According to a particularly advantageous embodiment of the invention, it is further provided that the grooves have a U- and / or V-shaped cross-section through which on the one hand a high lubricant reservoir can be provided, but at the same time also a good lubricant distribution is ensured.

Wie bereits eingangs dargestellt, kann der Türfeststeller integraler Bestandteil eines Türscharniers sein. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Rastfläche an einer Türhaltestange ausgebildet ist und das Rastelement in Richtung auf die Türhaltestange vorgespannt ist. Gemäß dieser Ausgestaltung der Erfindung weist der Türfeststeller eine üblicherweise mit der Fahrzeugkarosserie verbindbare Türhaltestange auf, welche über den Schwenkbereich der Kraftfahrzeugtür mit einem an der Kraftfahrzeugtür angeordneten Rastelement in Eingriff befindlich ist, wobei durch eine Verschwenkung der Kraftfahrzeugtür eine Bewegung der Rastfläche gegenüber dem Rastelement erfolgt. Eine Vorspannung des Rastelements in Richtung auf die Türhaltestange gewährleistet dabei eine zuverlässige Anordnung des Rastelements an der Rastfläche, wodurch die Funktion des Türfeststellers in besonderer Weise gewährleistet wird.As already mentioned, the door lock can be an integral part of a door hinge. According to a particularly advantageous embodiment of the invention, however, it is provided that the latching surface is formed on a door retaining bar and the latching element is biased in the direction of the door retaining bar. According to this embodiment of the invention, the door lock on a usually connectable to the vehicle body door retaining rod, which is located over the pivot region of the motor vehicle door with a arranged on the motor vehicle door latching element in engagement, wherein by pivoting the motor vehicle door, a movement of the locking surface relative to the locking element. A bias of the locking element in the direction of the door retaining rod ensures a reliable arrangement of the locking element on the locking surface, whereby the function of the door arrester is guaranteed in a special way.

Die Anordnung des Rastelements kann ebenfalls grundsätzlich in beliebiger Weise erfolgen. Im Rahmen eines Türscharniers mit integriertem Türfeststeller kann das Rastelement beispielsweise in einer entsprechenden Aufnahme in dem Türscharnier angeordnet sein, wobei die Anordnung derart erfolgt, dass eine Anlage an der Rastfläche gewährleistet ist. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass im Falle der vorteilhafterweise vorgesehenen Anordnung der Rastfläche an einer Türhaltestange das in Richtung auf die Türhaltestange vorgespannte Rastelement an einer Rastschwinge angeordnet ist. Die Verwendung einer Rastschwinge ermöglicht es, über den Abstand der gelenkigen Anordnung der Rastschwinge zu dem Rastelement sowie über die gewählte Vorspannung die Anpresskraft des Rastelements an der Kontaktfläche in einfacher Weise einzustellen.The arrangement of the locking element can also basically be done in any way. In the context of a door hinge with an integrated door arrester, the detent element can be arranged, for example, in a corresponding receptacle in the door hinge, the arrangement being such that an abutment on the detent surface is ensured. According to a particularly advantageous embodiment of the invention, however, it is provided that in the case of advantageously provided arrangement of the locking surface on a door retaining rod in the direction of the door retaining rod biased locking element is arranged on a latching rocker. The use of a latching rocker makes it possible to adjust over the distance of the articulated arrangement of the latching rocker to the locking element as well as the selected bias the contact pressure of the locking element on the contact surface in a simple manner.

In Fig. 1 ist eine erste Ausführungsform einer Rastschwinge 2a eines Türfeststellers 9 dargestellt, bei dem ein Rastelement 1a einstückig mit der Rastschwinge 2a ausgebildet ist. Im Bereich seiner Kontaktfläche mit einer Rastfläche 6 einer Türhaltestange 7 weist das Rastelement 1a zwei zueinander sowie bezüglich der Bewegungsrichtung der Rastfläche 6 gegenüber dem Rastelement 1a geneigten, mit Schmierstoff füllbare Nuten 3a auf. Die Rastschwinge 2a weist zur verschwenkbaren Anordnung einen Gelenkbolzen 4 auf, mittels dem die Rastschwinge 2a an einem Haltegehäuse 10 des Türfeststellers 9 gelenkig angeordnet werden kann (vgl. Fig. 1 -4).In Fig. 1 a first embodiment of a latching rocker 2a of a door arrester 9 is shown, in which a latching element 1a is formed integrally with the latching rocker 2a. In the region of its contact surface with a latching surface 6 of a door retaining bar 7, the latching element 1a has two grooves 3a which are inclined with respect to the direction of movement of the latching surface 6 relative to the latching element 1a and can be filled with lubricant. The latching rocker 2a has a hinge pin 4 for pivoting arrangement, by means of which the latching rocker 2a can be articulated to a holding housing 10 of the door arrester 9 (cf. Fig. 1 -4 ).

Eine alternative Ausgestaltung einer Rastschwinge 2b ist in Fig. 2 dargestellt. Diese weist im Gegensatz zu der in Fig. 1 und 3 dargestellten Rastschwinge 2a eine sich senkrecht zur Bewegungsrichtung der Rastfläche 6 gegenüber dem Rastelement 1b erstreckende Nut 3b auf. Wie aus Fig. 3 ersichtlich weist der Türfeststeller 9 zwei Rastschwingen 2a auf, welche an gegenüberliegenden Seiten der Türhaltestange 7 an den Rastflächen 6 anliegen. Eine in die Rastschwinge 2a eingebrachte, dem Rastelement 1a gegenüberliegend angeordnete Vertiefung 5a dient zur Aufnahme einer hier nicht dargestellten Schraubendruckfeder, mittels derer die Rastschwingen 2a in Richtung auf die Türhaltestange 7 vorgespannt sind.An alternative embodiment of a latching rocker 2b is in Fig. 2 shown. This, in contrast to the in Fig. 1 and 3 illustrated latching rocker 2a a perpendicular to the direction of movement of the locking surface 6 relative to the latching element 1b extending groove 3b. How out Fig. 3 it can be seen, the door lock 9 on two locking wings 2a, which abut on opposite sides of the door retaining bar 7 on the locking surfaces 6. An introduced into the locking rocker 2a, the latching element 1a oppositely disposed recess 5a serves to receive a helical compression spring, not shown here, by means of which the latching arms 2a are biased in the direction of the door retaining bar 7.

In Fig. 4 ist ein Türfeststeller 9 mit alternativ ausgestalteten Rastschwingen 2c dargestellt, bei denen die Vertiefungen 5b die parallel zur Türhaltestange 7 erfolgende Anordnung der Schraubendruckfeder 12 ermöglichen. Die aus einer kunststoffummantelten Metallstange gebildete Türhaltestange 7 des Türfeststellers 9 ist einerseits über einen Bolzen 14 gelenkig mit einer Säulenkonsole 15 verbunden. Über die Säulenkonsole 15, welche eine Öffnung 16 zur Aufnahme einer hier nicht dargestellten Befestigungsschraube aufweist, ist die Türhaltestange 7 verschwenkbar an einer hier nicht dargestellten Fahrzeugkarosserie befestigbar. Die Türhaltestange 7 ist in einer Durchtrittsöffnung eines an einer hier nicht dargestellten Fahrzeugtür festlegbaren Haltergehäuses 10 angeordnet. Im Falle eines Verschwenkens der Fahrzeugtür gegenüber der Fahrzeugkarosserie wird das an der Fahrzeugtür befestigte Haltergehäuse 10 relativ gegenüber der Türhaltestange 7 verschoben, wobei zur Festlegung eines maximalen Öffnungswinkels der Fahrzeugtür die Türhaltestange 7 an ihrem der Fahrzeugtür zugewandten Ende einen Anschlagkörper 8 aufweist, der an seiner dem Haltergehäuse 10 zugewandten Seite zur Dämpfung des Endanschlages einen Dämpfungskörper besitzt.In Fig. 4 a door lock 9 is shown with alternatively configured latching rockers 2c, in which the recesses 5b allow the parallel to the door holding rod 7 taking place arrangement of the helical compression spring 12. The door retaining rod 7 of the door arrester 9, which is formed from a plastic-coated metal rod, is connected, on the one hand, by means of a bolt 14 to an articulated column console 15. About the column bracket 15, which has an opening 16 for receiving a fastening screw, not shown here, the door retaining rod 7 is pivotally mounted on a vehicle body, not shown fastened here. The door retaining bar 7 is arranged in a passage opening of a holder housing 10 which can be fixed to a vehicle door (not shown here). In the case of a pivoting of the vehicle door relative to the vehicle body, the fastened to the vehicle door holder housing 10 is displaced relative to the door retaining bar 7, wherein defining a maximum opening angle of the vehicle door, the door retaining bar 7 at its end facing the vehicle door has a stopper body 8, at its the Holder housing 10 facing side for damping the end stop has a damping body.

Die Türhaltestange 7 weist an ihrer -in der Einbaulage Ober- und Unterseite- Rastflächen mit 6 Rastnuten 17 auf, die mit den Rastelementen 1c, die durch die Schraubendruckfedern 12 in Richtung auf die Rastflächen 6 vorgespannt sind, in Eingriff befindlich sind.The door retaining bar 7 has at its -in the installed position top and bottom locking surfaces with 6 locking grooves 17 which are engaged with the locking elements 1 c, which are biased by the compression coil springs 12 in the direction of the locking surfaces 6, in engagement.

Die Rastschwingen 2c sind auf den im Haltergehäuse 10 befestigten Gelenkbolzen 4 gelagert, die sich senkrecht zur durch den Gelenkbolzen 14 vorgegebenen Schwenkachse der Fahrzeugtür erstrecken. Die Schraubendruckfedern 12 sind einerseits an einer Anlagefläche 5b der Rastschwingen 2c und andererseits an einer in das Haltergehäuse 10 einschraubbaren und die Federkraft festlegenden Einstellschraube 13 abgestützt und spannen die Rastschwingen 2c in Richtung auf die Ober- und Unterseite der Türhaltestange 7 vor.The latching rockers 2 c are mounted on the hinge pin 4 fixed in the holder housing 10, which extend perpendicular to the predetermined by the hinge pin 14 pivot axis of the vehicle door. The helical compression springs 12 are on the one hand on a contact surface 5b of the latching rockers 2c and on the other hand on a screwed into the holder housing 10 and the spring force setting adjusting screw 13 is supported and bias the latching rockers 2 c in the direction of the top and bottom of the door retaining rod 7.

Im Bereich der Kontaktfläche 6 angeordnete, in Fig. 4 nicht dargestellte Nuten der Rastelemente 1c bilden ein Schmiermitteldepot, welches im Falle einer Verstellung der Türhaltestange 7 gegenüber den Rastschwingen 2 eine gleichmäßige und dauerhafte Schmierung gewährleistet.In the area of the contact surface 6 arranged in Fig. 4 not shown grooves of the locking elements 1c form a lubricant reservoir, which ensures a uniform and permanent lubrication in the case of an adjustment of the door retaining bar 7 relative to the latching rockers 2.
