Description

Rückenlehne mit regelbarer Rückenunterstützung für Kraftfahrzeugsitze Die Erfindung betrifft eine Rückenlehne mit regelbarer Rückenunterstützung für Kraftfahrzeugsitze mit einer Polsterung und einer oder mehreren waagerecht verlaufenden, in Richtung zur Rückenlehnenoberfläche hin eine Vorwölbung aufweisenden Stützfedern, wobei die Enden der Stützfedern auf am Rahmen der Rückenlehne befestigten Gleitschienen gegeneinander parallel zur Rückenlehnenoberfläche bewegbaren Schlitten gehalten sind.Backrest with adjustable back support for motor vehicle seats The invention relates to a backrest with adjustable back support for motor vehicle seats with a padding and one or more horizontally, in the direction of support springs having a protrusion towards the backrest surface, the Ends of the support springs on slide rails attached to the frame of the backrest against each other are held parallel to the backrest surface movable carriage.

Eine Rückenlehne dieser Art ist bereits Gegenstand eines älteren, nicht vorveröffentlichten Patentes. Hierbei weisen die Schlitten gegenläufige Gewinde auf und werden durch eine Gewindespindel bewegt.A backrest of this type is already the subject of an older, unpublished patent. The carriages have opposing threads and are moved by a threaded spindle.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art weiter zu verbessern.The invention is based on the object of an arrangement of the initially mentioned type to further improve.

Die Erfindung ist demgemäß darin zu sehen, daß der eine Schlitten mit dem einen Ende der Seele und der zweite Schlitten mit dem einen Ende der Ummantelung eines Bowdenzuges verbunden ist, wogegen das andere Ende der Seele an einem am Rahmen der Rückenlehne angebrachten Verstellhebel und das andere Ende der Ummantelung ortsfest am Rahmen der Rückenlehne angebracht ist.The invention is accordingly to be seen in the fact that the one slide with one end of the core and the second slide with one end of the sheath a Bowden cable is connected, whereas the other end of the soul is connected to one on the frame the backrest attached adjusting lever and the other end of the sheath stationary attached to the frame of the backrest.

Es ist hierbei vorteilhaft, wenn der mit einem Griff versehene Verstellhebel einen Zapfen trägt, der in Bohrungen einer gleichfalls am Rahmen der Rückenlehne sitzenden Rastscheibe einrastet.It is advantageous here if the adjusting lever is provided with a handle carries a pin, which is also in holes on the frame of the backrest seated locking disc engages.

Nach einem weiteren Merkmal der Erfindung sind der Verstellhebel und die Rastscheibe seitlich neben dem Sitzpolster angeordnet.According to a further feature of the invention, the adjusting lever and the locking disc is arranged laterally next to the seat cushion.

Die Erfindung wird im folgenden an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with reference to one in the drawing Embodiment explained in more detail.

Der Kraftfahrzeugsitz weist eine Rückenlehne 1 auf, an deren seitlichen Gestellteilen Gleitschienen 4 und 5 befestigt sind. In den Gleitschienen 4 und 5 sind Schlitten 2 und 3 verschiebbar gelagert, an denen die Enden einer Stützfeder 6 angreifen. Der Schlitten 3 ist mit dem freien Ende einer Seele 7 eines Bowdenzuges verbunden, dessen Ummantelung 8 mit ihrem freien Ende 9 an dem Schlitten 2 befestigt ist. Das andere Ende der Seele 7 ist an einem Verstellhebe110 befestigt, während das andere Ende der Ummantelung 8 über eine Halterung 11 ortsfest am Gestell der Rückenlehne festgelegt ist. Der mit einer Handhabe 12 versehene Verstellhebel 10 ist am Gestell der Rückenlehne schwenkbar gelagert und trägt einen Zapfen 13, der mit Bohrungen 14 in einer Rastscheibe 15 zusammenwirkt.The motor vehicle seat has a backrest 1 , on the side frame parts of which slide rails 4 and 5 are attached. Carriages 2 and 3, on which the ends of a support spring 6 engage, are slidably mounted in the slide rails 4 and 5. The carriage 3 is connected to the free end of a core 7 of a Bowden cable, the casing 8 of which is attached to the carriage 2 by its free end 9. The other end of the core 7 is attached to an adjustment lever 110, while the other end of the casing 8 is fixed in place on the frame of the backrest via a bracket 11. The adjusting lever 10, which is provided with a handle 12, is pivotably mounted on the frame of the backrest and carries a pin 13 which cooperates with bores 14 in a locking disk 15.

Bei Schwenken des Verstellhebels 10 beispielsweise in Richtung des Pfeiles 16 werden die Schlitten 2 und 3 in Richtung der Pfeile 17 und 18, also gegenläufig, bewegt, wodurch die Stützfeder 6 gespannt und somit ihr Mittelteil nach vorn vorgewölbt wird.When pivoting the adjusting lever 10, for example, in the direction of the Arrow 16, the carriages 2 and 3 in the direction of arrows 17 and 18, i.e. in opposite directions, moves, whereby the support spring 6 is tensioned and thus its central part arched forward will.
