Abstract
Description
Die Erfindung betrifft einen Kraftfahrzeug-Rücksitz nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle rear seat the preamble of claim 1.
Bei einem Kraftfahrzeug-Rücksitz der bekannten Art (GB 22 47 616 A) wird jeder Teilbereich einer geteilt vorklappba ren Rückenlehne in der Teilungsebene durch eine zusätzliche Verriegelungsvorrichtung in der Gebrauchslage gegen uner wünschtes Vorklappen, z. B. bei einem Frontalaufprall, ge sichert. Die Verriegelungsvorrichtung verwendet eine Klin ke, die von einer Feder an einem Bolzen anliegend gehalten wird. Diese Verriegelung ist nicht ausreichend sicher, weil durch die bei einem Unfall auftretenden Kräfte die Klinke außer Eingriff geraten kann.In a motor vehicle rear seat of the known type (GB 22 47 616 A) each section of a foldable foldable ren backrest in the division level by an additional Locking device in the use position against un desired folding, e.g. B. in a frontal impact, ge backs up. The locking device uses a clin ke held by a spring on a bolt becomes. This lock is not sufficiently secure because due to the forces occurring in an accident can disengage.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine einfache Verriegelungsvorrich tung zu schaffen, die auch hohen Belastungen standhält.The invention is based on this prior art based on the task of a simple locking device creating that also withstands high loads.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Anspruchs 1.This problem is solved with the features of Claim 1.
Die Verriegelungsvorrichtung verstärkt den Rahmen der Rüc kenlehne im Scharnierbereich und schafft eine steife Ver bindung zwischen Rückenlehne und Karosserie im Bereich der Teilungsebene der Rückenlehne. Bei der formschlüssigen Ver bindung einer Klaue mit einem karosseriefesten Bolzen wir ken keine auf die Rückenlehne ausgeübten Kräfte in Entrie gelungsrichtung der Verriegelungsvorrichtung.The locking device reinforces the frame of the back backrest in the hinge area and creates a stiff ver bond between backrest and body in the area of Partition level of the backrest. With the positive Ver We tie a claw with a body-fixed bolt no forces exerted on the backrest in the entrance direction of locking device.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result from the subclaims.
Nachstehend wird eine bevorzugte Ausführungsform der Erfin dung anhand der Zeichnungen näher erläutert. Es zeigen:The following is a preferred embodiment of the invention dung explained with reference to the drawings. Show it:

Fig. 6 - eine perspektivische Darstellung des Bolzens des Mittenscharniers nach Fig. 5. FIG. 6 - is a perspective view of the bolt of the center hinge of FIG. 5.
Die Rückenlehne eines Kraftfahrzeug-Rücksitzes ist im Ver hältnis ein drittel zu zwei drittel geteilt ausgeführt. Von den Rückenlehnenteilen 1 und 2 sind in Fig. 1 nur die Leh nenteilrahmen 1a und 2a dargestellt. Die Rückenlehnenteile 1 und 2 sind mit äußeren Scharnieren 1b und 2b und einem gemeinsamen Mittenscharnier 3 um eine Schwenkachse 3b schwenkbar an der Karosserie 4 angelenkt. An dem Mitten scharnier 3 sind Torsionsfedern 1c und 2c undrehbar befe stigt, die den Kraftaufwand für das Hochklappen der Rücken lehnenteile 1 und 2 verringern.The backrest of a motor vehicle rear seat is designed in relation to one third to two thirds divided. Of the seat back parts 1 and 2 are 1, only the Leh in Fig. Nenteilrahmen 1 a and 2. a. The backrest parts 1 and 2 are hinged to the body 4 with outer hinges 1 b and 2 b and a common center hinge 3 about a pivot axis 3 b. At the middle hinge 3 torsion springs 1 c and 2 c are rotatably BEFE Stigt that reduce the effort for folding the backrest parts 1 and 2 .
Die Verriegelung der Rückenlehnenteile 1 und 2 ist nur für das in Fig. 1 rechte Rückenlehnenteil 1 und auch nur für die Innenseite des Rückenlehnenteils 1 dargestellt. Die Verriegelung des Rückenlehnenteils 2 erfolgt spiegelbild lich mit den gleichen Elementen. Eine Verriegelungsvorrich tung 5 wird durch einen Betätigungshebel 6 entriegelt, der auch die nicht dargestellte, allgemein übliche Verriegelung im oberen, äußeren Bereich des Rückenlehnenteils 1 entrie gelt. Die Bewegung des Betätigungshebels 6 wird von einem Bowdenzug 6a auf die Verriegelungsvorrichtung 5 übertragen.The locking of the backrest parts 1 and 2 is only shown for the right backrest part 1 in FIG. 1 and also only for the inside of the backrest part 1 . The locking of the backrest part 2 is mirror image Lich with the same elements. A locking device 5 is unlocked by an operating lever 6 , which also unlocks the generally not shown locking in the upper, outer region of the backrest part 1. The movement of the operating lever 6 is transmitted from a Bowden cable 6 a to the locking device 5 .
Der Bowdenzug 6a ist in dem als Hohlprofil ausgeführten, linken vertikalen Holm des Lehnenteilrahmens 1a geführt und mit einem Ende darin festgeklemmt. Die Seele 6b des Bowden zuges 6a ist mit einer Stange 5c verbunden, die am gegen überliegenden Ende eine Verriegelungsklaue 5a aufweist. Die Verriegelungsklaue 5a umgreift einen Bereich 3c eines undrehbar mit der Aufnahme 3d verbunden Bolzens 3f. The Bowden cable 6 a is guided in the left vertical spar of the backrest frame 1 a, which is designed as a hollow profile, and is clamped at one end therein. The soul 6 b of the Bowden pull 6 a is connected to a rod 5 c which has a locking claw 5 a at the opposite end. The locking claw 5 a engages around an area 3 c of a non-rotatably connected to the receptacle 3 d bolt 3 f.
Die Aufnahme 3d ist mit einem Beschlagteil 3a einstückig ausgebildet, mittels dessen die Aufnahme 3d fest mit der Karosserie 4 verbunden ist, die in Fig. 3 nur im Bereich der Verschraubung des Beschlagteils 3a dargestellt ist. Die Aufnahme 3d weist in jeder Seitenwand jeweils einen Aufnah meschlitz 3h auf, in den der mit gegenüberliegenden Quernu ten 3i versehene Bolzen 3f undrehbar eingesetzt wird. Der Bolzen 3f wird durch einen Lagerdeckel 3e in der Aufnahme 3d gehalten.The receptacle 3 d is formed in one piece with a fitting part 3 a, by means of which the receptacle 3 d is firmly connected to the body 4 , which is shown in FIG. 3 only in the area of the screw connection of the fitting part 3 a. The receptacle 3 d has a receptacle slot 3 h in each side wall, into which the bolt 3 f provided with opposite transverse grooves 3 i is rotatably inserted. The bolt 3 f is held by a bearing cover 3 e in the receptacle 3 d.
Auf dem Bolzen 3f lagert der Rückenlehnenteil 1 mit einer Lagerhülse 1d. Zwischen dem Lagerbereich 3k für die Lager hülse 1d und der Aufnahme 3d ist der Bolzen 3f mit einander diametral gegenüberliegenden Quernuten 3g versehen, deren Nutgrund parallele Flächen 31 aufweist, an denen die Ver riegelungsklaue 5a mit ihren Seitenflanken 5d anliegt. In dem von der Aufnahme 3d wegweisenden Ende des Bolzens 3f verläuft in dem Bolzen 3f in Längsrichtung ein Schlitz 3m, in den die Torsionsfeder 1c eingehängt ist.On the bolt 3 f, the backrest part 1 is supported with a bearing sleeve 1 d. Between the bearing area 3 k for the bearing sleeve 1 d and the receptacle 3 d, the bolt 3 f is provided with diametrically opposite transverse grooves 3 g, the bottom of which groove has parallel surfaces 31 , on which the locking claw 5 a rests with its side flanks 5 d . In the end of the bolt 3 f pointing away from the receptacle 3 d, a slot 3 m runs in the bolt 3 f in the longitudinal direction, into which the torsion spring 1 c is suspended.
Die Führung der Stange 5c im inneren Vertikalholm des Leh nenteilrahmens 1a ist in Fig. 4 erkennbar. In dem Hohlpro fil des Lehnenteilrahmens 1a sind Führungselemente 1e ange ordnet, in denen die Stange 5c unter der Wirkung der Feder 5b nach unten geschoben oder von der Seele 6b des Bowdenzu ges 6a nach oben gezogen wird. Dabei gleiten die Seiten flanken 5d über den Bereich 3c am Bolzen 3f und blockieren die Schwenkbewegung des Rückenlehnenteils 1.The leadership of the rod 5 c in the inner vertical spar of the back part frame 1 a can be seen in Fig. 4. In the Hohlpro fil of the backrest frame 1 a guide elements 1 e are arranged, in which the rod 5 c is pushed down under the action of the spring 5 b or pulled by the soul 6 b of the Bowdenzu 6 a upwards. The sides of slide edges 5d on the portion 3 c at pins 3 f and block the pivoting movement of the backrest part 1.
