Abstract
Description
Die Erfindung betrifft ein Lagerelement zur schwenkbaren Lagerung einer Rücksitzlehne. The invention relates to a bearing element for pivotable storage a back seat back.
Bei vielen modernen Fahrzeugtypen ist die Rücksitzlehne schwenkbar gelagert, um die Rücklehne im Bedarfsfall umklappen zu können. Dadurch kann insbesondere das Ladevolumen im Fahrzeug vergrößert werden. Vielfach ist die Rücksitzlehne auch geteilt umklappbar, so dass die Rücksitzlehne beispielsweise im Verhältnis 1/3 zu 2/3 wahlweise umgeklappt werden kann. The backrest of many modern vehicle types can be swiveled stored so that the backrest can be folded down if necessary. In particular, this can increase the loading volume in the vehicle become. In many cases, the rear seat back can also be folded over so that the rear seat back, for example, in a ratio of 1/3 to 2/3 can be folded down.
Zur Fixierung der Rücksitzlehne in der Normalposition sind an der Oberseite der Rücksitzlehne in der Regel Riegel vorgesehen, die an der Karosserie des Fahrzeuges lösbar eingerastet werden können. An der Unterseite sind die Rücksitzlehnen in an der Karosserie befestigten Lagerelementen schwenkbar gelagert. To fix the back seat back in the normal position are on the Top of the back seat backrest is usually provided on the latch Body of the vehicle can be releasably engaged. At the Bottom are the rear seat backrests attached to the body Bearing elements pivotally mounted.
Diese gattungsgemäßen Lagerelemente müssen verschiedenste Anforderungen erfüllen. Zum einen müssen die Lagerelemente möglichst leicht sein und dürfen nur ein geringes Bauvolumen aufweisen. Andererseits muss ein Ausreißen der Rücksitzlehne aus der Befestigung auch im Falle eines Frontalcrashs, bei dem durch das im Kofferraum untergebrachte Gepäck erhebliche Kräfte auf die Rücklehne wirken können, zuverlässig ausgeschlossen sein. Insofern fordern die Fahrzeughersteller eine hohe mechanische Festigkeit der gattungsgemäßen Lagerelemente, um ein Ausreißen der Rücklehne aus dem Lagerelement auch im Falle von Frontalcrashs auszuschließen. These generic bearing elements must be very different Meet requirements. First, the bearing elements must be as light as possible be and may only have a small construction volume. on the other hand the rear seat back must be pulled out of the attachment in the event of of a head-on crash, in which the one housed in the trunk Luggage can exert significant forces on the backrest reliably be excluded. In this respect, vehicle manufacturers are demanding a high level mechanical strength of the generic bearing elements to a Tear out the backrest from the bearing element even in the case of Exclude frontal crashes.
Aufgabe der vorliegenden Erfindung ist es, ein neues Lagerelement zur Lagerung von schwenkbaren Rücklehnen vorzuschlagen. The object of the present invention is to provide a new bearing element Propose storage of swiveling backrests.
Diese Aufgabe wird durch ein nachfolgend beschriebenes Lagerelement gelöst. This task is accomplished by a bearing element described below solved.
Eine Ausführungsform des erfindungsgemäßen Lagerelements ist in den Zeichnungen dargestellt und wird nachfolgend beispielhaft erläutert. Es zeigen: An embodiment of the bearing element according to the invention is in the Drawings shown and is explained below by way of example. It demonstrate:
Fig. 1 ein schematisch dargestelltes Lagerelement in perspektivischer Ansicht; Figure 1 is a schematically illustrated bearing element in a perspective view.
Fig. 2 das Lagerelement gemäß Fig. 1 in seitlicher Ansicht; Fig. 2 shows the bearing element of Figure 1 in a side view.
Fig. 3 das Lagerelement gemäß Fig. 1 in Ansicht von hinten; FIG. 3 shows the bearing element of Figure 1 in rear view.
Fig. 4 einen zur Herstellung des in Fig. 1 dargestellten Lagerelements geeigneten Drahtbügel in seitlicher Ansicht; . Fig. 4 is a suitable for the manufacture of the bearing member shown in Figure 1 wire hanger in side view;
Fig. 5 eine zur Herstellung des in Fig. 1 dargestellten Lagerelements geeignete Grundplatte in seitlicher Ansicht. Fig. 5 is a base plate suitable for producing the bearing element shown in Fig. 1 in a side view.
Das in Fig. 1 dargestellte Lagerelement 01 wird im Wesentlichen aus einer mit der Fahrzeugkarosserie verschraubbaren Grundplatte 02, einem daran befestigten Drahtbügel 03 und einer vom Drahtbügel 03 umschlungenen Lagerbuchse 04 gebildet. Nach Montage des Lagerelements 01 in einem Fahrzeug liegt die Grundplatte 02 zumindest abschnittsweise flächig auf der Karosserie des Fahrzeuges auf und wird mittels durch die Ausnehmungen 05 in der Grundplatte 02 durchgesteckter Halteschrauben fixiert. Der Drahtbügel 03 erstreckt sich nach der Fixierung der Grundplatte 02 in einer Vertikalebene, die sich in Richtung der Längsachse des Fahrzeuges erstreckt. Das eine Ende einer nicht dargestellten Achse, die an der Fahrzeugrücklehne befestigt ist, wird in die Lagerbuchse 04 seitlich eingesteckt, so dass die Rücksitzlehne eine Schwenkbewegung um den Mittelpunkt 06 (s. Fig. 2) der Lagerbuchse 04 ausführen kann. The bearing element 01 shown in FIG. 1 is essentially formed from a base plate 02 that can be screwed to the vehicle body, a wire bracket 03 attached to it and a bearing bush 04 wrapped around by the wire bracket 03. After mounting the bearing element 01 in a vehicle, the base plate 02 lies flat on the body of the vehicle at least in sections and is fixed by means of retaining screws inserted through the recesses 05 in the base plate 02. After the base plate 02 has been fixed, the wire bracket 03 extends in a vertical plane which extends in the direction of the longitudinal axis of the vehicle. One end of an axle, not shown, which is fastened to the vehicle backrest, is inserted laterally into the bearing bush 04, so that the rear seat back can pivot about the center point 06 (see FIG. 2) of the bearing bush 04.
Wie in Fig. 2 dargestellt, sind die Enden 07 und 08 des Drahtbügels 03 durch Ausnehmungen 09 in der Grundplatte 02 durchgesteckt und werden durch Anbringung kurzer Schweißnähte mit der Grundplatte verbunden. Alternativ ist auch die Vernietung denkbar. As shown in Fig. 2, the ends 07 and 08 of the wire bracket 03 are inserted through recesses 09 in the base plate 02 and are connected to the base plate by applying short welds. Alternatively, riveting is also conceivable.
In Fig. 4 ist der Drahtbügel 03 in seitlicher Ansicht dargestellt. Durch entsprechende Biegebearbeitung kann aus einem Drahtmaterial, beispielsweise Stahldraht, ein derartiger Drahtbügel 03 hergestellt werden. Ausgehend von den Enden 07 und 08 des Drahtbügels 03 wird dabei ein Auge 10 gebildet, das die Lagerbuchse 04 umfasst und dadurch am Drahtbügel 03 fixiert. Im Bereich zwischen den Enden 07 und 08 ist der den Drahtbügel 03 bildende Draht 11 nach innen gebogen, so dass dadurch am Drahtbügel 03 zwei Deformationszonen 12 und 13 gebildet werden. Im Falle eines Fahrzeugcrashs, bei dem erhebliche Kräfte in Richtung der Fahrzeuglängsachse auf den Drahtbügel 03 wirken, kann in den Deformationszonen 12 und 13 eine große Verformungsenergie aufgenommen werden. Das Abreißen des Drahtbügels 03 selbst bei sehr hohen Belastungen ist dadurch und durch die hohe mechanische Stabilität des Drahts 11 in Belastungsrichtung wirksam ausgeschlossen. In Fig. 4 the wire bracket 03 is shown in a side view. Appropriate bending processing can be used to produce such a wire bracket 03 from a wire material, for example steel wire. Starting from the ends 07 and 08 of the wire bracket 03, an eye 10 is formed which encompasses the bearing bush 04 and is thereby fixed on the wire bracket 03. In the area between the ends 07 and 08, the wire 11 forming the wire bracket 03 is bent inwards, so that two deformation zones 12 and 13 are thereby formed on the wire bracket 03. In the event of a vehicle crash, in which considerable forces act on the wire bracket 03 in the direction of the vehicle longitudinal axis, a large deformation energy can be absorbed in the deformation zones 12 and 13 . The tearing off of the wire bracket 03 even under very high loads is effectively excluded as a result of this and the high mechanical stability of the wire 11 in the direction of loading.
Der zur Herstellung des Drahtbügels 03 verwendete Draht 11 kann einen kreisringförmigen oder sonstigen prismatischen Querschnitt aufweisen. The wire 11 used to produce the wire bracket 03 can have an annular or other prismatic cross section.
In Fig. 5 ist die Grundplatte 02 des Lagerelements 01 in seitlicher Ansicht dargestellt. Auch an der Grundplatte 02 ist eine Deformationszone 14 vorgesehen, in der sich die Grundplatte 02 bei Auftreten von Belastungen in Richtung der Längsachse des Fahrzeuges kontrolliert deformieren kann. Außerdem erstreckt sich der mittlere Abschnitt 15 der Grundplatte 02, an dem die Enden 07 und 08 des Drahtbügels 03 befestigt sind, schräg von unten nach oben, so dass die vom Drahtbügel 03 im Falle eines Crashs übertragenen Kräfte mit einem großen Normalkraftanteil abgefangen werden können. In FIG. 5 the base plate 02 of the bearing member is shown in side view 01. A deformation zone 14 is also provided on the base plate 02, in which the base plate 02 can deform in a controlled manner when loads occur in the direction of the longitudinal axis of the vehicle. In addition, the central section 15 of the base plate 02, to which the ends 07 and 08 of the wire bracket 03 are attached, extends obliquely from bottom to top, so that the forces transmitted by the wire bracket 03 in the event of a crash can be intercepted with a large proportion of normal force.
Durch die Verwendung eines sich in Längsachse des Fahrzeugs erstreckenden Drahtes zur Schaffung der Verbindung zwischen Grundplatte und Achslagerung der Rücksitzlehne kann eine hochstabile Verbindung bei relativ geringem Gewicht und geringem Bauvolumen realisiert werden. Außerdem wird durch das gezielte Vorsehen von Deformationszonen am Lagerelement die Aufnahme von Crashenergie durch gezielte Verformung der Bauteile ermöglicht. Durch Anwendung zumindest einer dieser beiden Maßnahmen bzw. durch die Verwirklichung beider Maßnahmen in einem Lagerelement wird die Belastbarkeit von Lagerelementen erheblich vergrößert. By using one in the longitudinal axis of the vehicle extending wire to create the connection between the base plate and axle mounting of the rear seat back can be a highly stable connection realized with a relatively low weight and low construction volume become. In addition, through the targeted provision of Deformation zones on the bearing element absorbing crash energy through targeted Deformation of the components allows. By using at least one of these two measures or by realizing both Measures in a bearing element will increase the resilience of Bearing elements significantly enlarged.
