Description

Die Erfindung bezieht sich auf eine Federabstützung für einen Kraftwagentürfeststeller, bei dem eine am einen Tür­anordnungsteil, Tür oder Türsäule, schwenkbar angelenkte ein am anderen Türanordnungsteil starr befestigtes Kalter­gehäuse durchsetzende starre Türhaltestange mittels einer auf dem freien Belastungsarm einer im Haltergehäuse ange­ordneten und an diesem über einen Stützarm abgestützten Drehstabfeder frei drehbar angeordneten Belastungsrolle beaufschlagt ist.The invention relates to a spring support for a motor vehicle door arrester, in which a rigid door holding rod, which is pivotably articulated on a door arrangement part, door or door pillar, penetrates a cold housing rigidly fastened to the other door arrangement part by means of a support arm arranged on the free loading arm and on this via a support arm supported torsion bar spring is freely rotatably mounted load roller.

Bei Kraftwagentürfeststellern dieser Bauart weist die zur Aufbringung einer Brems- bzw. Haltekraft des Türfeststellers erforderliche, als Torsionsfeder ausgebildete Belastungsfeder jeweilseine S- bzw. C-förmige Krümmung auf und ist über ihren Schaftteil und ferner auch über ihren Belastungsarm innerhalb des Haltergehäuses gehalten bzw. abgestützt, der­art, daß ihr freier Belastungsarm beim Durchgang der Rastaus­nehmungen der Türhaltestange durch das Haltergehäuse ausge­lenkt wird. Diese Auslenkung des Belastungsarmes der Türhal­testange bewirkt, wie sich in der Praxis herausgestellt hat, auch eine verdrehung des Schaftteiles der Drehstabfeder gegnüber dem ihn abstützenden Bereichen des Haltegehäuses, woraus eine Geräuschentwicklung innerhalb des Türfeststellers resultiert, die mit zunehmender Betriebsdauer des Türfest­stellers und damit mit zunehmender Auslaibung der Abstützung des Schaftteiles der Drehstabfeder größer wird. Man hat versucht diesem Problem der Geräuschentwicklung mittels einer Fettung des Schaftteiles der Türhaltestange beizukom­men, jedoch hat sich gezeigt, daß diese Maßnahme nicht aus­reichend ist, um eineGeräuschentwicklung innerhalb des Türfeststellers über dessen gesamte Lebensdauer hin zu un­terbinden. Weiterhin ist es bei mit einer als Torsionsfeder ausgebildeten Belastungsfeder ausgestatteten, mit einem aus Schanierprofilen gebildeten Türscharnier baulich verei­nigten Türfeststellern bekannt, den Schaftteil der Torsions­feder vermittels einer Lagerschale aus wartungsfreiem Lager­material in einer entsprechenden Ausnehmung des Scharnierflü­gelblattes der einen Scharnierhälfte zu lagern, wobei die Festlegung von Schaftteil der Torsionsfeder und Lagerschale mittels den Schaftteil der Torsionsfeder übergreifender Verprägungen des Scharnierflügelblattes erfolgt. Eine solche Abstützung der Torsionsfeder ist aber nur dort möglich, wo der Schaftteil der Torsionsfeder über eine ausreichende Läng hin in einer Ausnehmung des Scharnierflügelblattes einliegt, so daß ein gewisses axiales Wandern der Lagerschale zugelassen werden kann, ohne daß sich daraus zu Geräuschent­wicklungen führende Berührungen zwischen dem Schaftteil der Torsionsfeder und dem ihn abstützenden Scharnierflügel­blatt ergeben.In motor vehicle door locks of this type, the load spring designed as a torsion spring for applying a braking or holding force of the door lock has an S- or C-shaped curvature and is held or supported within the holder housing via its shaft part and also via its load arm , in such a way that its free load arm is deflected by the holder housing during the passage of the locking recesses in the door holding rod. As has been found in practice, this deflection of the load arm of the door holding rod also causes the shaft part of the torsion bar spring to rotate relative to the regions of the holding housing which support it, which results in a noise development within the door arrester, which increases with the operating time of the door arrester and thus with increasing rebound the support of the shaft part of the torsion bar spring becomes larger. Attempts have been made to solve this problem of noise generation by greasing the shaft part of the door holding rod, but it has been shown that this measure is not sufficient to prevent noise development within the door stay over its entire service life. It is also used as a torsion spring trained load spring equipped, with a door hinge formed from hinge profiles structurally combined door locks known to store the shaft part of the torsion spring by means of a bearing shell made of maintenance-free bearing material in a corresponding recess of the hinge leaf of one hinge half, the fixing of the shaft part of the torsion spring and the bearing shell Torsion spring overlapping embossments of the hinge leaf. Such support of the torsion spring is only possible where the shaft part of the torsion spring lies over a sufficient length in a recess of the hinge leaf, so that a certain axial movement of the bearing shell can be allowed without this resulting in noise leading to contact between the Part of the shaft of the torsion spring and the hinge leaf supporting it.

Der Erfindung liegt daher die Aufgabe zugrunde einen auch unabhängig von den Türscharnieren einsetzbaren Türfeststeller mit einem aus einem Blechmaterialzuschnitt gefalteten Halter­gehäuse ausgestatteten Torsionsfeder-Türfeststeller der eingangs genannten Bauart dahingehend weiter zu verbessern, daß er auch bei einem geringstmöglichen Herstellungsaufwand über seine gesamte Lebensdauer hin geräuschfrei arbeitet.The invention is therefore based on the object of using a door arrester which can also be used independently of the door hinges and is equipped with a torsion spring door arrester of the type mentioned at the beginning, which folds out of a sheet metal material blank, in such a way that it operates without noise over its entire service life even with the least possible production outlay.

Diese Aufgabe wird erfindungsgemäß dadrurch gelöst, daß die Drehstabfeder in einer Langlochausnehmung des aus einem Blechmaterialzuschnitt gefalteten Haltergehäsuses aufgenommen und hinsichtlich ihres Schaftteiles innerhalb des Halter­gehäuses über eine Lagerschale aus selbstragendem und wartungsfreiem Lagermaterial abgestützt ist, wobei die Lagerschale zusätzlich zu mechanisch wirkenden Haltemitteln durch eine vorgewählte Vorspannung zwischen Schaftteil und Stützarm in ihrer Lage innerhalb des Haltergehäuses gehalten ist. Dabei überbrückt die Lagerschale den Zwischenraum zwischen den beiden die Abstützung des Schaftteiles der Drehstabfeder bildenden Seitenwandungen des Haltergehäu­ses und ist gegen ein Wandern in axialer Richtung zusätzlich durch radial zu ihrem Profilquerschnitt abgestellte, an den Außenflächen der Seitenwandungen des Haltergehäuses anliegende Ohren geschützt. Aus dieser Anordnung und Ausbil­dung der Lagerschale resultiert eine dauerhafte, über die gesamte Lebensdauer des Türfeststellers hin reichende war­tungs- und reibungsfreie Abstützung des Schaftteiles der Torsionsfeder, die ihererseits eine daernde Geräuschfreiheit gewährleistet. Ausgehend von dem Umstand, daß die Lagerschale im Wesentlichen durch die Vorspannung zwischen Schaftteil und Stützarm der Drehstabfeder innerhalb der Ausnehmung der Seitenwände des Haltergehäuses gehalten ist erfordert auch die Realisierung dieser Lagerung des Schaftteiles der Torsionsstabfeder keinen besonderen zusätzlichen Herstel­lungsaufwand des Türfeststellers.This object is achieved according to the invention in that the torsion bar spring is received in an elongated hole recess of the holder housing folded from a sheet material blank and its shaft part is supported within the holder housing by means of a bearing shell made of self-supporting and maintenance-free bearing material, the bearing shell being additionally preselected by mechanically acting holding means is held in position within the holder housing between the shaft part and the support arm. The bearing shell bridges the space between the two to support the shaft part of the Torsion bar spring forming side walls of the holder housing and is additionally protected against wandering in the axial direction by radially positioned ears resting on the outer surfaces of the side walls of the holder housing. This arrangement and design of the bearing shell results in a permanent, maintenance-free and friction-free support of the shaft part of the torsion spring that extends over the entire service life of the door arrester, which in turn guarantees a lasting freedom from noise. Based on the fact that the bearing shell is held essentially by the pretension between the shaft part and the support arm of the torsion bar within the recess of the side walls of the holder housing, the implementation of this mounting of the shaft part of the torsion bar spring does not require any special additional manufacturing outlay for the door arrester.

Eine zusätzliche Lagensicherung der Lagerschale kann ohne weiteren Herstellungsaufwand für den Türfeststeller dadurch erreicht werden, daß die Lagerschale über die radial zu ihrem Profilquerschnitt ausgestellten Ohren gleichzeitig auch in den Außenflächen der Seitenwandungen des Halterge­häuses verkrallt ist, was in einfachster Weise dadurch ermöglicht wird, daß die Ohren einen spitzwinkelig zur Längsachse der Lagerschale gerichteten Zuschnitt aufweisen.An additional securing of the position of the bearing shell can be achieved without further manufacturing effort for the door arrester in that the bearing shell is at the same time also clawed in the outer surfaces of the side walls of the holder housing via the radially flared ears, which is made possible in the simplest way that the ears have a cut directed at an acute angle to the longitudinal axis of the bearing shell.

Gemäß einer weiteren bevorzugten Ausgestaltungsform der Erfindung kann auch vorgesehen sein, daß die Lagerschale wenigstens einen radial nach außen gerichteten Vorsprung aufweist, über den sie innerhalb des Haltergehäuses an dessen Querwandung gegen ein Wandern sowohl in Umfangs- als auch in Längrichtung gesichert festgelegt ist.According to a further preferred embodiment of the invention, it can also be provided that the bearing shell has at least one radially outward projection by means of which it is secured within the holder housing on its transverse wall to prevent it from wandering in both the circumferential and longitudinal directions.

Dabei liegt es im Rahmen der Erfindung, daß der radial nach außen gerichtete Vorsprung der Lagerschale durch wenigstens eine die Lagerschale bezüglich ihrer Längserstreckung und bezüglich ihres Querschnittsprofiles mittig angeordnete Warze gebildet ist.
In diesem Zusammenhang kann naturgemäß auch vorgesehen sein, daß die Lagerschale über mehrere radial zu ihrem Quer­schnittsprofil gerichtete radiale Vorsprünge oder Warzen gegen ein Wandern an einer Querwandung oder an den beiden Seitenwandungen des Haltergehäuses abgestützt ist.It is within the scope of the invention that the radially outward projection of the bearing shell is arranged centrally by at least one of the bearing shell with respect to its longitudinal extent and with respect to its cross-sectional profile Wart is formed.
In this context, it can of course also be provided that the bearing shell is supported against migration on a transverse wall or on the two side walls of the holder housing via a plurality of radial projections or warts directed radially to its cross-sectional profile.
