Description

Die Erfindung bezieht sich auf einen Kraftwagentürfeststeller gemäß dem Oberbegriff des Anspruchs 1, bestehend aus einem am einen Türanordnungsteil, Tür oder Türsäule, starr befestigten Haltergehäuse und einer dieses durchsetzenden, am anderen Türanordnungsteil um eine zur Türscharnierachse parallele Achse schwenkbar angelenkten, an mindestens einer von zwei ihrer einander gegenüberliegenden Oberflächen mit Brems- und Rastmarken versehenen Türhaltestange, und zwei mit der Türhaltestange, insbesondere den Brems- oder Rastmarken der Türhaltestange zusammenwirkenden, durch Wälzkörper gebildeten Bremskörpern, deren einer als Widerlager um eine feststehend im Haltergehäuse angeordnete Achse und deren anderer in einem gegen eine Federlast im wesentlichen quer zur Bewegungsebene der Türhaltestange schwenkbar im Haltergehäuse angeordneten Halter aus Kunststoffmaterial aufgenommen und gelagert ist, wobei die Schwenklagerachse des schwenkbeweglichen Halters in einem einem Mehrfachen des Durchmessers des Bremskörpers entsprechenden Abstand von dessen Rotationsachse angeordnet ist..The invention relates to a motor vehicle door arrester according to the preamble of claim 1, consisting of a holder housing rigidly attached to a door arrangement part, door or door pillar, and a holder housing passing through it and pivotally articulated on the other door arrangement part about an axis parallel to the door hinge axis, on at least one of two their mutually opposite surfaces with brake and locking marks provided door holding rod, and two with the door holding rod, in particular the braking or locking marks of the door holding rod, formed by rolling bodies, one of which acts as an abutment around a fixedly arranged in the holder housing and the other in one against a spring load is received and mounted essentially transversely to the plane of movement of the door holding rod pivotably arranged in the holder housing made of plastic material, the pivot bearing axis of the pivoting holder in one measurement times the diameter of the brake body corresponding distance from the axis of rotation is arranged ..

Ein derartiger Kraftwagentürfeststeller ist bereits aus der US-A-2 724 143 bekannt.Such a motor vehicle door arrester is already known from US-A-2 724 143.

Bei einer anderen, aus dem DE-GM 83 32 456, bekannten Bauart von Kraftwagentürfeststellern sind zwei einander gegenüberliegend angeordnete, mit einer Türhaltestange zusammenwirkende, als Walzen ausgebildete Bremskörper jeweils in einem im wesentlichen aus Kunststoffmaterial gebildeten Halter drehbar aufgenommen, wobei die Halter schräg zur Bewegungsebene der Türthaltestange ausgerichtet und in entsprechend ausgebildeten Lagerflächen des Haltergehäuses kippbar gelagert sowie durch kissenförmige Gummifedern in Richtung auf die Bewegungsebene der Türhaltestange hin federbelastet sind, derart, daß die Bremskörper unter der Last der Gummifedern wenigstens an den Brems- bzw. Rastrampen der Türhaltestange anliegen.
Abgesehen davon, daß eine solche Bauart von Türfeststellern nur in Verbindung mit einer doppelseitig mit Brems- oder Rastmarken bildenden Erhebungen versehenen Türhaltestange und dementsprechend auch zur Tüthaltestange symetrisch angeordneten und einzeln federbeaufschlagten Bremskörpern anwendbar ist, ist die Verwendung von Gummifedern zur Belastung der Bremskörper grundsätzlich mit dem Nachteil behaftet, daß Gummifedern stets temperaturabhängig sind, d.h. daß sich die Anpresskraft der Bremskörper an die Türhaltestange entsprechend der Erwärmung bzw. der Abkühlung der Gummifedern ändert, woraus naturgemäß erhebliche Schwankungen in der Brems- bzw.Haltekraft des Türfeststellers resultieren. Eine exakte Festlegung des Haltepunktes bzw. des jeweils zugelassenen Öffnungswinkels der Fahrzeugtür ist daher auch bei dieser Ausbildung eines Türfeststellers grundsätzlich nicht möglich.In another, from DE-GM 83 32 456, known type of motor vehicle door locks, two oppositely arranged, interacting with a door holding rod, designed as rollers are rotatably received in a holder essentially made of plastic material, the holder being inclined to the plane of movement the door support rod aligned and tiltably mounted in appropriately designed bearing surfaces of the holder housing and spring-loaded by pillow-shaped rubber springs in the direction of the plane of movement of the door support rod, such that the brake bodies bear at least on the braking or locking ramps of the door support rod under the load of the rubber springs.
Apart from the fact that such a type of door lock can only be used in conjunction with a door retaining bar provided with double-sided elevations forming brake or locking marks and accordingly also symmetrically arranged to the retaining bar and individually spring-loaded brake bodies, the use of rubber springs for loading the brake body is basically possible with the Disadvantageous that rubber springs are always temperature-dependent, ie the contact pressure of the brake body on the door support rod changes in accordance with the heating or cooling of the rubber springs, which naturally results in considerable fluctuations in the braking or holding force of the door arrester. An exact determination of the stopping point or the respectively permitted opening angle of the vehicle door is therefore fundamentally not possible even with this design of a door arrester.

Schließlich ist noch eine Bauart von Türfeststellern (EP-PS 2 175) bekannt, bei welcher einem in einem Haltergehäuse feststehend angeordneten Brems- oder Widerlagerkörper gegenüberliegend ein walzenförmiger Bremskörper angeordnet ist, wobei der walzenförmige Bremskörper gegen die Last einer Gummifeder verstellbar in einer schräg gegen die Bewegungsebene der Türhaltestange angestellten schachtförmigen Führung des Haltergehäuses aufgenommen ist. Die Türhaltestange ist dabei aus einem Flachmaterialzuschnitt gebildet und lediglich an einer ihrer beiden Breitseiten mit einer doppelseitig ansteigenden Bremsrampe versehen. Der allen mit einer Gummifeder bzw. einer Feder aus gummiähnlichem Material ausgestatteten Türfeststellern anhaftende Nachteil einer temperaturabhängigen Verstellung bzw. Veränderung der erreichbaren Brems- oder Haltekraft bzw. des Haltepunktes kann auch mit dieser Bauart eines Türfeststellers nicht beseitigt werden. Ferner erfordert diese bekannte Art der Federbelastung des Bremskörpers eine besonders aufwendige Lagerung desselben, da eine Lagerung unmittelbar gegen die Gummifeder mit Rücksicht auf die zur Vermeidung von Geräuschbildungen erforderliche Drehwilligkeit des walzenförmigen Bremskörpers nicht infrage kommt.Finally, a type of door arrester (EP-PS 2 175) is known, in which a roller-shaped brake body is arranged opposite a brake or abutment body fixedly arranged in a holder housing, the drum-shaped brake body adjustable against the load of a rubber spring is accommodated in a shaft-shaped guide of the holder housing which is inclined against the plane of movement of the door holding rod. The door support rod is formed from a flat material blank and is only provided on one of its two broad sides with a braking ramp rising on both sides. The disadvantage of a temperature-dependent adjustment or change in the achievable braking or holding force or the stopping point, which is inherent in all door locks equipped with a rubber spring or a spring made of rubber-like material, cannot be eliminated even with this type of door lock. Furthermore, this known type of spring loading of the brake body requires a particularly complex mounting of the same, since mounting directly against the rubber spring is out of the question with regard to the need to rotate the roller-shaped brake body to avoid noise.

Der Erfindung liegt daher die Aufgabe zugrunde einen Türfeststeller der eingangs genannten Bauart (vgl. die US-A-2 724 143) dahingehend zu verbessern, daß auch bei einer Serienfertigung eine von Umwelteinflüssen wie Temperatur und dergl. unabhängige, äußerst feinfühlige Einstellung des Brems- oder Haltepunktes des Türfeststellers erreicht wird, ohne daß dadurch der Herstellungsaufwand oder das Bauvolumen des Türfeststellers erhöht werden.The invention is therefore based on the object of improving a door arrester of the type mentioned at the outset (cf. US Pat. No. 2,724,143) in such a way that, even in series production, an extremely sensitive adjustment of the braking, independent of environmental influences such as temperature and the like. or stopping point of the door arrester is reached without thereby increasing the manufacturing outlay or the construction volume of the door arrester.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens der in dem gegen eine Federlast quer zur Bewegungsebene der Türhaltestange beweglichen Halter aufgenommene Bremskörper durch eine über stegförmige Lagerflächenabschnitte unmittelbar im Halter gelagerte Stahlnadel gebildet ist.This object is achieved in that at least the brake body received against a spring load transversely to the plane of movement of the door holding rod is formed by a steel needle mounted directly in the holder via web-shaped bearing surface sections.

Die erfindungsgemäße Gestaltung eines Türfeststellers erlaubt somit die Verwendung wenigstens eines als Stahlnadel ausgebildeten Bremskörpers und dessen unmittelbare Lagerung in dem als Formteil aus Kunststoffmaterial gebildeten Halter, wobei der verhältnismäßig kleine Durchmesser einer Stahlnadel darüberhinaus die Sicherstellung einer exakten Einhaltung der Haltepunkte der Türe gewährleistet, ohne daß die Gefahr eines Festklemmens der Stahlnadel ihrer Lagerung, insbesondere im schwenkbar angeordneten Halter, besteht. Ferner kann ohne Erhöhung des erforderlichen Herstellungsaufwandes die Verwendung einer Metallfeder zur Belastung der mit der Türhaltestange zusammenwirkenden Stahlnadel angewandt werden, so daß auch jedwede Temperaturabhängigkeit in der Wirkung des Türfeststellers ausgeschlossen ist.The design of a door arrester according to the invention thus allows the use of at least one brake body designed as a steel needle and its immediate storage in the holder formed as a molded part made of plastic material, the relatively small diameter of a steel needle also ensuring the exact adherence to the stopping points of the door without the There is a risk of the steel needle jamming in its storage, in particular in the pivotably arranged holder. Furthermore, the use of a metal spring for loading the steel needle interacting with the door holding rod can be used without increasing the required manufacturing outlay, so that any temperature dependence in the effect of the door arrester is also excluded.

In einer ersten bevorzugten Ausführungsform, ist der schwenkbewegliche Halter an einer feststehend im Haltergehäuse angeordneten Lagerachse aufgehängt und durch eine Metallfeder belastet ist, wobei die diesem zugeordnete Belastungsfeder tangential zum Umfang der in ihm gelagerten Stahlnadel am schwenkbaren Halter angreift.In a first preferred embodiment, the pivotable holder is suspended from a bearing shaft arranged in a fixed manner in the holder housing and is loaded by a metal spring, with the load spring assigned to it tangentially to the circumference of the steel needle mounted in it on the swiveling holder.

In einer weiteren bevorzugten Ausführungsform ist dabei vorgesehen, daß die den schwenkbeweglichen Halter belastende Feder durch eine über Stützarme gegen das Haltergehäuse abgestützte und über einen zentralen Belastungsarm an ihm angreifende Wickelfeder gebildet ist, deren Windungen konzentrisch zur Lagerachse des schwenkbeweglichen Halters angeordnet sind. Außer durch eine solche Wickelfeder kann die erforderliche Federbelastung des schwenkbaren Halters aber auch durch andere Formen von Federn, insbesondere durch den Belastungsarm einer über einen Stützarm, insbesondere an den Lagerstegen des Haltergehäuses abgestützten U- oder S-förmigen Drehstabfeder aufgebracht werden, wobei dann der an den Lagerstegen des Haltergehäuses festgelegte Stützarm der Drehstabfeder gleichzeitig die Lagerung des schwenkbaren Halters bilden kann.In a further preferred embodiment it is provided that the spring loading the pivotable holder is formed by a coil spring which is supported by support arms against the holder housing and engages on it via a central loading arm, the windings of which are arranged concentrically to the bearing axis of the pivotable holder. In addition to such a clock spring, the required spring loading of the pivotable holder can also be applied by other forms of springs, in particular by the loading arm of a U-shaped or S-shaped torsion bar spring supported by a support arm, in particular on the bearing webs of the holder housing, in which case the the bearing webs of the holder housing fixed support arm of the torsion bar can simultaneously form the storage of the pivotable holder.

Der im schwenkbeweglichen Halter aufgenommenen Stahlnadel ist als Widerlager für die Türhaltestange zweckmäßigerweise ein in einem feststehenden Halter aufgenommener bzw. um eine feststehende Achse drehbar im Haltergehäuse gelagerter Bremskörper mit größerem Durchmesser zugeordnet.The steel needle accommodated in the pivotable holder is expediently assigned, as an abutment for the door holding rod, a brake body with a larger diameter which is accommodated in a fixed holder or rotatable in the holder housing about a fixed axis.

Die Türhaltestange des Türfeststellers kann in verschiedener Weise, insbesondere in jeder bekannten Weise ausgebildet und angeordnet sein, wobei bei einer ersten Ausgestaltungsform die Türhaltestange aus einem Flachmaterialzuschnitt mit lediglich einseitig angeordneten Brems- oder Rastrampen gebildet ist.The door holding rod of the door arrester can be designed and arranged in various ways, in particular in any known manner, with the door holding rod being formed from a flat material blank with braking or locking ramps arranged on only one side in a first embodiment.

Nach einer anderen vorteilhaften Ausgestaltungsform kann aber auch vorgesehen sein, daß eine im schwenkbaren Halter gelagerte Stahlnadel oder Längenabschnitte einer dreiteilig ausgebildeten Stahlnadel mit einer durch einen Rundmaterialabschnitt gebildeten Türhaltestange zusammenwirken, wobei die Türhaltestange zur Bildung von Brems- oder Rastmarken quer zu ihrer Längsachse verformt ist und wobei ein als Rolle oder Walze ausgebildeter, im feststehend angeordneten Halter oder über eine feststehende Achse im Haltergehäuse gelagerter, mit der aus Rundmaterial gebildeten Türhaltestange zusammenwirkender Brems- oder Widerlagerkörper mit einer nutförmigen Umfangsvertiefung als Führung für die Türhaltestange versehen ist.According to another advantageous embodiment, it can also be provided that a steel needle mounted in the pivotable holder or longitudinal sections of a three-part steel needle cooperate with a door holding rod formed by a round material section, the door holding rod being deformed transversely to its longitudinal axis to form brake or detent marks and a brake or abutment body designed as a roller or roller, in the fixedly arranged holder or mounted on a fixed axis in the holder housing and interacting with the door holding rod made of round material, is provided with a groove-shaped circumferential recess as a guide for the door holding rod.

Nach einer weiteren vorteilhaften Ausgestaltungsform kann ferner vorgesehen sein, daß eine aus einem Flachmaterialzuschnitt gebildete Türhaltestange beidseitig mit Brems- oder Rastmarken bildenden Erhebungen bzw. Vertiefungen versehen ist und in wenigstens einer der Brems- oder Rastmarken bildenden Erhebungen dieser Türhaltestange eine dem Durchmesser der Stahlnadel bzw. eines von drei Längenabschnitten einer Stahlnadel entsprechende zusätzliche Vertiefung vorgesehen ist. Die die Brems- oder Rastmarken bildenden Erhebungen der Türhaltestange sind zweckmäßig durch in der Draufsicht zueinander parallele streifenförmige Ausformungen gebildet, wobei die zusätzliche Ausnehmung oder Vertiefung in lediglich einer dieser streifenförmigen Ausformungen angeordnet ist. Die zusätzliche Ausnehmung oder Vertiefung in einer der Brems- oder Rastmarken bildenden Erhebungen der Türhaltestange ist vorteilhaft auf die Anlagebreite eines Längenabschnittes einer in insgesamt drei Längenabschnitte unterteilten Stahlnadel beschränkt.According to a further advantageous embodiment, it can further be provided that a door holding rod formed from a flat material blank is provided on both sides with elevations or depressions forming brake or detent marks and in at least one elevation of this door holding rod forming brake or detent marks a diameter of the steel needle or one of three longitudinal sections of a steel needle corresponding additional depression is provided. The elevations of the door holding rod which form the braking or locking marks are expediently formed by strip-shaped formations which are parallel to one another in the plan view, the additional recess or depression being arranged in only one of these strip-shaped formations. The additional recess or depression in one of the elevations of the door holding rod forming the braking or locking marks is advantageously limited to the contact width of a length section of a steel needle divided into a total of three length sections.

Der in den Figuren 1 bis 9 im einzelnenen dargestellte Kraftwagentürfeststeller besteht im wesentlichen aus einem Haltergehäuse 1 und einer dieses durchsetzenden Türhaltestange 2. Das Haltergehäuse 1 ist aus einem einteiligen Flachmaterialzuschnitt geformt und weist an zwei einander gegenüberliegende aufragende Lagerstege 3 anschließende Befestigungslappen 4 auf, über welche das Haltergehäuse 1 vermittels Schraubenbolzen 5 an das zugehörige, in der Zeichnung nicht dargestellte, Türanordnungsteil angeschlagen ist. Ferner weist das Haltergehäuse 1 zwei parallel zur Bewegungsebene der Türhaltestange 2 gerichtete Halteschenkel 6 für einen feststehend im Haltergehäuse 1 anzuordnenden Halter 7 eines um eine feststehende Achse drehbaren Bremskörpers 8 auf.The motor vehicle door arrester shown in detail in FIGS. 1 to 9 essentially consists of a holder housing 1 and a door holding rod 2 passing through it. The holder housing 1 is formed from a one-piece flat material blank and has fastening tabs 4 adjoining two opposing upstanding bearing webs 3, via which the holder housing 1 is struck by means of screw bolts 5 on the associated door arrangement part, not shown in the drawing. Furthermore, the holder housing 1 has two holding legs 6, which are directed parallel to the plane of movement of the door holding rod 2, for a holder 7 of a brake body 8 which can be rotated about a fixed axis and which can be arranged in the holder housing 1.

Im Haltergehäuse 1 ist ein erster Halter 7 feststehend angeordnet, wobei der Halter 7, wie insbesondere aus den Figuren 6 und 7 ersichtlich, aus einem Kunststoffmaterialblock besteht und mit einer Aufnahmeausnehmung 9 für einen drehbaren Bremkörper 8 versehen ist. Der Bremskörper 8 ist im wesentlichen walzenförmig ausgebildet und über seine beiden Seitenabschnitte 10 in die Halteklauen 11 des Halters 7 eingeklipst, wobei die Stirnenden der Ausnehmung 9 bogenförmig gestaltet sind, derart, daß dem Bremskörper 8 eine gewisse Schwenkbeweglichkeit verbleibt. Ferner ist der Bremskörper 8 reibungsarm und daher leicht drehbar lediglich über stegförmige Lagerflächenabschnitte im Halter 7 gelagert. Im Haltergehäuse 1 ist ferner ein zweiter Halter 12 angeordnet, der ebenfalls durch einen Kunststoffmaterialblock gebildet und um eine Achse 13 schwenkbar an den Lagerstegen 3 des Haltergehäuses 1 aufgehängt ist. Bezüglich der Aufnahme und Lagerung einer Stahlnadel 14 ist der zweite Halter 12 ebenso gestaltet, wie der erste Halter 7. Wie im Übrigen auch bei allen weiteren gezeigten Ausgestaltungsformen weist die im schwenkbar aufgehängten Halter 12 angeordnete Stahlnadel 14 einen geringen Durchmesser auf und ist über lediglich stegförmige Lagerflächen gegen den Halter 12 abgestützt. In seinem oberen Bereich weist der Halter 12 eine Durchgangsbohrung 15 für die Achse 13 auf, wobei die Achse 13, wie insbesondere aus der Figur 2 ersichtlich durch einen Spannstift 16 gebildet ist. Bei dem in den Figuren 1 bis 9 dargestellten Ausführungsbeispiel ist der Bremskörper 8ebenso wie die Stahlnadel 14 walzenförmig mit geringem Durchmesser ausgebildet und leicht drehbar im den Haltern 7 aufgenommen. Der Abstand zwischen der Rotationsachse 17 der Stahlnadel 14 und der Schwenklagerachse 13 des Halters 12 beträgt, wie aus der Figur 1 ersichtlich ein mehrfaches des Durchmessers der Stahlnadel 14. Der schwenkbar im Haltergehäuse 1 gelagerte Halter 12 ist durch eine Wickelfeder belastet, wobei die Windungen 18 der Wickelfeder konzentrisch zur Aufhängeachse 13 des Halters 12 angeordnet sind und der Belastungsarm 19 der Wicklelfeder am Rücken 20 des Halters 12 in einer solchen Lage angreift, daß die Federkraft tangential zum Umfang der Stahlnadel 14 gerichtet ist. Die Türhaltestange 2 weist hier beidseitig Bremsrampen 21 und 22 sowie Rastmarken 23 und 24 auf. Im Übrigen ist die Türhaltestange 2 aus einem Flachmaterialzuschnitt geformt und sind die Bremsrampen 21,22 bzw. Rastmarken 23,24 an den beiden Breitseiten der Türhaltestange 2 ausgeformt, wie insbesondere aus den Darstellungen der Figuren 3 und 4 ersichtlich ist.A first holder 7 is fixedly arranged in the holder housing 1, the holder 7, as can be seen in particular from FIGS. 6 and 7, consists of a block of plastic material and is provided with a receiving recess 9 for a rotatable brake body 8. The brake body 8 is essentially roller-shaped and is clipped into the holding claws 11 of the holder 7 via its two side sections 10, the front ends of the recess 9 being arcuate in such a way that the brake body 8 remains somewhat pivotable. Furthermore, the brake body 8 is low-friction and therefore easily rotatable only in the holder 7 via web-shaped bearing surface sections. A second holder 12 is also arranged in the holder housing 1, which is likewise formed by a block of plastic material and is suspended on the bearing webs 3 of the holder housing 1 so that it can pivot about an axis 13. With regard to the reception and storage of a steel needle 14, the second holder 12 is designed in the same way as the first holder 7. As is also the case with all the other embodiments shown, the steel needle 14 arranged in the pivotably suspended holder 12 has a small diameter and is merely web-shaped Bearing surfaces supported against the holder 12. In its upper region, the holder 12 has a through hole 15 for the axis 13, the axis 13, as can be seen in particular from FIG. 2, being formed by a spring pin 16. In the exemplary embodiment shown in FIGS. 1 to 9, the brake body 8, like the steel needle 14, is cylindrical in shape with a small diameter and is easily rotatably received in the holders 7. The distance between the axis of rotation 17 of the steel needle 14 and the pivot bearing axis 13 of the holder 12 is, as can be seen from FIG. 1, a multiple of the diameter of the steel needle 14. The holder 12, which is pivotably mounted in the holder housing 1, is loaded by a coil spring, the windings 18 the coil spring is arranged concentrically to the suspension axis 13 of the holder 12 and the loading arm 19 of the coil spring on the back 20 of the holder 12 engages in such a position that the spring force is directed tangentially to the circumference of the steel needle 14. The door support rod 2 points here on both sides Brake ramps 21 and 22 and detent marks 23 and 24. Otherwise, the door holding rod 2 is formed from a flat material blank and the braking ramps 21, 22 or locking marks 23, 24 are formed on the two broad sides of the door holding rod 2, as can be seen in particular from the illustrations in FIGS. 3 and 4.

Bei dem im Ausführungsbeispiel nach den Figuren 10 bis 13 dargestellten Türfeststeller weist eine ebenfalls aus einem Flachmaterialzuschnitt geformte Türhaltestange 32 lediglich an ihrer einen Breitseite Bremsrampen 33 und Rastmarken 34 auf, über welche sie mit einer in einem schwenkbar im Haltergehäuse 1 aufgehängten Halter 12 angeordneten Stahlnadel 14 zusammenwirkt. Die Bremsrampen 33 und Rastmarken 34 sind dabei lediglich über einen Teil der Gesamtbreite der Türhaltestange 32 hin ausgebildet, derart, daß beiderseits der Bremsrampen 33 glattflächige Abschnitte verbleiben und die Türhaltestange 32 über ihre gesamte Länge hin eine geradlinige und glattflächige Rückseite 35 aufweist, über welche sie gegen einen walzenförmigen Bremskörper 36 abgestützt ist. Der Bremskörper 36 ist hierbei im wesentlichen als Widerlagerrolle bzw. Widerlagerwalze ausgebildet und vermittels einer hohlen Lagerachse 37 um eine feststehende Achse 38 drehbar in den Lagerstegen 3 des Haltergehäuses 1 gelagert und weist einen erheblich grösseren Durchmesser als die mit den Bremsrampen 33 bzw. den Rastmarken 34 zusammenwirkende, im schwenkbaren Halter 12 angeordnete Stahlnadel 14 auf.In the door arrester shown in the exemplary embodiment according to FIGS. 10 to 13, a door holding rod 32 likewise formed from a flat material blank has braking ramps 33 and detent marks 34 only on one broad side thereof, via which they have a steel needle 14 arranged in a holder 12 pivotably suspended in the holder housing 1 cooperates. The braking ramps 33 and locking marks 34 are formed over only a part of the total width of the door holding rod 32 in such a way that smooth areas remain on both sides of the braking ramps 33 and the door holding rod 32 has a straight and smooth rear surface 35 over its entire length, over which it is supported against a roller-shaped brake body 36. The brake body 36 is here essentially designed as an abutment roller or abutment roller and is rotatably supported by means of a hollow bearing axis 37 about a fixed axis 38 in the bearing webs 3 of the holder housing 1 and has a considerably larger diameter than that with the brake ramps 33 or the detent marks 34 cooperating steel needle 14 arranged in the pivotable holder 12.

Bei dem Ausführungsbeispiel nach den Figuren 14 und 15 ist die Türhaltestange 52 durch einen Rundmaterialabschnitt gebildet, der zur Bildung von Bremsrampen 53 und Rastmarken 54 quer zu seiner Längsachse verformt ist. Mit der Türhaltestange 52 wirkt auf der einen Seite eine Stahlnadel 55, welche in einem um eine Achse 13 schwenkbar im Haltergehäuse 1 gelagerten Halter 12 aufgnommen ist zusammen. Auf der anderen Seite wirkt mit der Türhaltestange 52 ein Bremskörper 56 zusammen, welcher als Widerlagerrolle mit verhältnismäßig großem Durchmesser ausgebildet und um eine feststehende Achse drehbar an den Lagerstegen 3 des Haltergehäuses 1 gelagert ist. Zur Erzeugung eines exakt wirkenden Haltepunktes des Türfeststellers ist hierbei weiterhin vorgesehen, daß an der Türhaltestange 52 dem tiefsten Punkt der Rastmarke 54 gegenüberliegend eine Vertiefung 59 bzw. eine Ausnehmung angeordnet ist, mit der die im schwenkbaren Halter 12 angeordnete Stahlnadel 55 zusammenwirkt und deren Profilquerschnitt dem Profilquerschnitt der Stahlnadel 55 entspricht. Der Bremskörper 56 dient der Türhaltestange 52 im wesentlichen als Widerlager und ist seinerseits als Walze ausgebildet sowie um eine feststehende Achse 57 drehbar an den Lagerstegen 3 des Haltergehäuses gelagert. Der Bremskörper 56 weist einen wesentlich größeren Durchmesser auf als die Stahlnadel 55 und ist in seinem mittleren Bereich mit einer der Türhaltestange 52 als Führung dienenden eine halbrunde Querschnittsform aufweisenden Umfangsnut 58 versehen. Die Belastung des schwenkbar im Haltergehäuse 1 aufgehängten Halters 12 erfolgt auch hierbei in der in den Figuren 1 bis 9 dargestellten und beschriebenen Weise durch eine Wickelfeder.In the exemplary embodiment according to FIGS. 14 and 15, the door holding rod 52 is formed by a round material section which is deformed transversely to its longitudinal axis to form braking ramps 53 and locking marks 54. A steel needle 55, which is received in a holder 12 which is pivotably mounted about an axis 13 in the holder housing 1, interacts with the door holding rod 52. On the other hand, a brake body 56 cooperates with the door holding rod 52, which is designed as an abutment roller with a relatively large diameter and rotatable about a fixed axis on the bearing webs 3 of the Holder housing 1 is mounted. To generate an exactly acting stopping point of the door arrester, it is further provided that a recess 59 or a recess is arranged on the door holding rod 52 opposite the lowest point of the locking mark 54, with which the steel needle 55 arranged in the pivotable holder 12 interacts and the profile cross section of which Profile cross section of the steel needle 55 corresponds. The brake body 56 serves the door support rod 52 essentially as an abutment and is in turn designed as a roller and rotatably mounted about a fixed axis 57 on the bearing webs 3 of the holder housing. The brake body 56 has a substantially larger diameter than the steel needle 55 and is provided in its central region with a circumferential groove 58 which has a semicircular cross-sectional shape and serves as a guide for the door holding rod 52. The load on the holder 12, which is pivotably suspended in the holder housing 1, also takes place here in the manner shown and described in FIGS. 1 to 9 by a coil spring.

In Verbindung mit dieser Ausbildung der Türhaltestange 62 ist die im schwenkbaren Halter 12 angeordnete Stahlnadel 67 dreiteilig ausgebildet, derart, daß die Stahlnadel 67 aus insgesamt drei walzenförmigen Längenabschnitten 140 besteht, die um eine gemeinsame Achse rotierend im Halter 12 aufgenommen sind. Der mit der glattflächigen Rückseite 68 der Türhaltestange 62 zusammenwirkende Bremskörper 69 dient als Widerlager für die Türhaltestange und ist als Walze mit verhältnismäßig großem Durchmesser ausgebildet sowie um eine feststehende Achse 70 drehbar in den Lagerstegen 3 des Haltergehäuses 1 gelagert. Die Belastung des schwenkbar im Haltergehäuse 1 gelagerten Halters 12 erfolgt auch bei dieser Ausführungsform in der in den Figuren 1 bis 9 gezeigten und beschriebenen Weise vermittels einer Wickelfeder.In the exemplary embodiment shown in FIGS. 16 to 18, the door holding rod 62 is formed from a flat material blank, which has braking ramps 63 and locking marks 64 which have moldings 65 arranged on one side on one of the two broad sides of the door holding rod, three molded moldings 65 arranged next to one another being provided in the exemplary embodiment shown. the two outer ones each have a substantially smooth surface of the braking ramps 53, while the inner shape 65 is provided with an additional recess or recess 66 which interacts with a steel needle 67 arranged in the holder 12 which is pivotably suspended in the holder housing 1 and an exact stopping point of the door arrester marked. In connection with this design of the door holding rod 62, the steel needle 67 arranged in the pivotable holder 12 is constructed in three parts, such that the steel needle 67 consists of a total of three roller-shaped longitudinal sections 140 which are received in the holder 12 rotating about a common axis. The one with the smooth back 68 of the door holding rod 62 cooperating brake body 69 serves as an abutment for the door holding rod and is designed as a roller with a relatively large diameter and rotatably mounted about a fixed axis 70 in the bearing webs 3 of the holder housing 1. The load on the holder 12 pivotably mounted in the holder housing 1 also takes place in this embodiment in the manner shown and described in FIGS. 1 to 9 by means of a clock spring.

Bei dem in den Figuren 19 und 20 dargestellten, im übrigen mit dem in den Figuren 14 und 15 dargestellten Ausführungsbeispiel übereinstimmenden Ausführungsbeispiel ist für die Belastung des schwenkbar im Haltergehäuse 1 aufgehängten Halters 12 eine U-förmige Drehstabfeder 80 vorgesehen, die über ihren einen Schenkel 81 am Haltergehäuse 1 festgelegt ist und mit ihrem zweiten, den Belastungsarm bildenden Schenkel 82 an der Rückseite des Halters 12 angreift. Der an den Lagerstegen 3 des Haltergehäuses 1 festgelegte Schenkel 81 der Drehstabfeder 80 dient hierbei gleichzeitig als Lagerachse für den schwenkbar im Haltergehäuse 1 aufgehängten Halter 12.In the exemplary embodiment shown in FIGS. 19 and 20, which otherwise corresponds to the exemplary embodiment shown in FIGS. 14 and 15, a U-shaped torsion bar spring 80 is provided for the load on the holder 12 pivotably suspended in the holder housing 1 is fixed to the holder housing 1 and engages with its second leg 82, which forms the loading arm, on the back of the holder 12.
