Description

Die Erfindung betrifft ein Sitzmöbel mit einem Gestell, einer Sitzfläche und einer Rückenlehne, wobei die Sitzfläche relativ zum Gestell nach vorne bzw. hinten verschiebbar ist und mit ihr die an sie angelenkte und am Gestell schwenkbar gelagerte RUckenlehne, auf deren Vorderseite eine vordere Rückenplatte aufliegt, die relativ zur Rückenlehne verschiebbar ist.The invention relates to a piece of seating furniture with a frame, a seat surface and a backrest, the seat surface being displaceable forwards or backwards relative to the frame and with it the backrest hinged to it and pivotably mounted on the frame, on the front side of which a front backplate rests, which is movable relative to the backrest.

Ein solches Sitzmöbel beschreibt die FR-PS 1 078 676. Nachteilig ist es dabei insbesondere, daß bei einer Verstellung der Neigung der Rückenlehne und damit auch der auf der RUckenlehne aufliegenden Rückenplatte der Lendenbereich einer auf dem Möbel sitzenden Person nur in der Liegeposition der RUckenlehne unterstützt wird. In allen anderen Positionen bis hin zur Sitzposition mit nahezu vertikaler Rückenlehne bleibt der Lendenbereich ununtsrattltzt.FR-PS 1 078 676 describes such seating. It is particularly disadvantageous that when the inclination of the backrest and thus also the backplate resting on the backrest is adjusted, the lumbar region of a person sitting on the furniture is only supported in the reclining position of the backrest becomes. In all other positions up to the sitting position with an almost vertical backrest, the lumbar area remains unsupported.

Die Erfindung vermeidet diese Nachteile. Ihr liegt die Aufgabe zugrunde. ein Sitzmöbel der eingangs genannten Art dahingehend auszugestalten, daß unabhängig von der jeweils vom Benutzer gewählten Neigung der Rückenlehne den Sitzmöbels der Lendenberaich stets unterstützt bleibt, wobei der Benutzer eine beliebige Neigung der Rückenlehne bei gleichzeitiger Verschiebung der Sitzfläche vornehmen kann, ohne daß dabei eine Relativverschiebung zwischen ihm bzw. seiner Kleidung und den einzelnen Teilen der Sitzfläche und der vorderen Rückenplatte erfolgt.The invention avoids these disadvantages. It is based on the task. to design a piece of seating furniture of the type mentioned in such a way that, regardless of the inclination of the backrest selected by the user, the seating furniture of the lumbar region is always supported, the user being able to make any inclination of the backrest while simultaneously displacing the seat surface without a relative displacement between he or his clothes and the individual parts of the seat and the front back plate.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die vordere Rückenplatte in ihrem mittleren Bereich durch ein sich im wesentlichen horizontal erstreckendes Gelenk in eine obere und eins untere Teilplatte unterteilt ist.To achieve this object, the invention is characterized in that the front back plate is divided into an upper and a lower part plate in its central region by an essentially horizontally extending joint.

Bei der ermähnten Verschiebungabewegung wird somit zusammen mit der Sitzfläche die Rückenlehne verachwenkt und gleichzeitig die auf ihr verschiebbar angebrachte vordere Rückenplatte relativ zur Rückenlehne verschoben, so daß die erwähnten nachteiligen Kräfte nicht mehr auftreten können. Bei dieser Verschiebung wird ein wachaendes Gebiet im Bereich des Gelenks zwischen Sitzfläche und Rückenlehne von der vorderen Rückenplatte aufgefüllt, so daß dadurch über den gesamten Veraohiebungaweg der Lendenwirbelbereich der betreffenden Person sehr gut und atandig abgestützt wird. Oberhalb das erwähnten horizontalen Gelenks der vordaren RUckenplatte ist diese weiter nach oben fortgwaatzt, so daß sion die vordere RUckenplatte zumindest bis zur Höhe der Rückenlehne erstreckt, die daher zum Benutzer hin vollständig abgedeckt ist. Die vordere Rückenpistte kann sich aber auch noch über die Rückenlehne hinaus nach oben erstrecken.When the movement is admonished, the backrest is pivoted together with the seat surface and, at the same time, the front backplate slidably mounted on it is displaced relative to the backrest, so that the aforementioned disadvantageous forces can no longer occur. During this shift, a wachaendes area in the area of the joint between the seat and backrest is filled by the front back plate, so that the lumbar vertebra area of the person in question is supported very well and steadily over the entire vera shift. Above the above-mentioned horizontal hinge of the front back plate, this is continued upward, so that the front back plate extends at least to the height of the backrest, which is therefore completely covered towards the user. The front back slope can also extend upwards beyond the backrest.

Es dient einer Erleichterung der Varsohiabungebewegung bei gleichzeitiger guter Führung der vorderen RUokenplatte und gegebenenfalls der Sitzfläche wenn Führungen an der Rückenlehne für die vordere Rüekanplatte im Bereich deren Gelenke, an Geatell für die untere Kante der vorderen Rückenplatte und/oder am Gestell für die Sitzfläche vorgesehen sind.It serves to facilitate the movement of the Varsohiabung while simultaneously guiding the front RUoken plate and, if necessary, the seat if guides are provided on the backrest for the front Rüekan plate in the area of their joints, on Geatell for the lower edge of the front back plate and / or on the frame for the seat .

Bei der erwähnten Verschiebung verschiebt sich auch die vordere Rückanplatte zussame mit der Sitzfläche nach vorne bzw. hinten. Es dient einer fühlbaren Verbeaaarung der Führung der vorderen Rückenplatte unterhalb ihres Gelenks, wenn ein Steg das gemeinsame Gelenk zwischen der Sitzfläche und der Rückenlehne einerseits mit der vorderen Rückenplatte andererseits gelenkig verbindet. Der Steg verschiebt gewissermaßen selbsttätig bei der erwähnten Verschiebung von Sitzfläche und vorderer Rückenplatte den unterhalb des Gelenks befindlichen Abschnitt der vorderen Rückenplatte relativ zum Gestell in der gewünschten Art und Weise.In the case of the mentioned displacement, the front back plate also moves together with the seat surface to the front or back. It serves for a tangible combination of the leadership the front back plate below its joint when a web connects the joint joint between the seat and the backrest on the one hand to the front back plate on the other. The web moves to a certain extent automatically when the seat and front back plate are shifted, the portion of the front back plate located below the joint relative to the frame in the desired manner.

Die hierbei aufzubringenden Kräfte sind besonders gering, wenn das Gelenk zwischen dem Steg und der vorderen Rückenplatte unter Abstand von der unteren Kante der vorderen Rückenplatte angebracht ist, wie es bevorzugt wird. Die Verhältnisse sind vorzugsweise dabei derart getroffen, daß der Steg mit der vorderen Rückenplatte in der Ruhelage des Sitzmöbels einen etwa rechten Winkel bildet.The forces to be exerted here are particularly low if the joint between the web and the front back plate is arranged at a distance from the lower edge of the front back plate, as is preferred. The conditions are preferably such that the web forms an approximately right angle with the front back plate in the rest position of the seating.

Bevorzugt wird es ebenfalls, wenn ein Federelement das Gestell mit der Sitzfläche verbindet, daß die Sitzfläche in die Ruhelage zieht. Stattdessen kann aber auch ein Druckelement vorgesehen sein, welches die Sitzfläche in die Ruhelage oder in die Ausgangslage drückt.It is also preferred if a spring element connects the frame to the seat surface that pulls the seat surface into the rest position. Instead, a pressure element can also be provided, which presses the seat surface into the rest position or into the starting position.

Falls das neuartige Sitzmöbel eine Kopfstütze hat, so wird deren Neigung ebenfalls nachgeführt, wobei die Rückenlehne und die vordere Rückenplatte hierzu im Nackenbereich gelenkig ausgebildet sind und ein Band die Sitzfläche mit dem obersten Teil der Rückenlehne verbindet. Das Band ist vorzugsweise als Stahlband ausgebildet. Bei der Verschiebung der Sitzfläohe nach vorne zieht daa Band, welches vorzugsweise an beiden Seiten angebracht ist, den obersten Teil der Sitzfläche ebenfalls nach vorne, so daß die im wesentlichen lotrechte Anordnung dieses obersten Teiles bei der Verschiebung im wesentlichen beibehalten bleibt. Dieselbe Verschwenkung wird auch dem obersten Teil der vorderen Rückenplatte mitgeteilt.If the novel seating furniture has a headrest, its inclination is also adjusted, the backrest and the front backplate being articulated in the neck area for this purpose and a band connecting the seat surface to the uppermost part of the backrest. The band is preferably designed as a steel band. When the seat surface is shifted forward, the band, which is preferably attached on both sides, also pulls the uppermost part of the seat forward, so that the essentially vertical arrangement of this uppermost part remains essentially unchanged during the shift. The same pivot is also communicated to the uppermost part of the front back plate.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere Wichtige Merkmale ergeben. Es zeigt:

  • Figur 1 die wesentlichen Bauelemente eines neuartigen Sitzmöbels in einer teilweise geschnittenen Seitenansicht, und zwar in der Ausgangsstellung des Sitzmöbels;
  • Figur 2 die Situation von Figur 1 in der nach vornt verschobenen Stellung der Sitzfläohe mit flacher, geneigter Rückenlehne.
The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result. It shows:
  • Figure 1 shows the essential components of a new type of seating in a partially sectioned side view, in the starting position of the seating;
  • Figure 2 shows the situation of Figure 1 in the forward shifted position of the seat with a flat, inclined backrest.

Zeichnerisch dargestellt ist ein mit einer Kopfstütze versehener Sessel ohne Armlehnen. Die beschriebenen Prinzipien lassen sich ebenso gut auf einen Stuhl oder ein anderes Sitzmöbel anwenden, beispielsweise einen Flugzeugsitz, Kraftfahrzeugsitz, Sessel usw., und zwar jeweils mit oder ohne Armlehnen.A chair with armrests without armrests is shown in the drawing. The principles described can equally well be applied to a chair or other seating, for example an aircraft seat, motor vehicle seat, armchair, etc., with or without armrests.

Das neuartige Sitzmöbel besteht aus einem Gestell 1, einer Sitzfläche 2, eine Rückenlehne 3 und einer an der Vorderseite der Rückenlehne befindlichen vorderen Rückenplatte 4. Eine Führungsschiene X verläuft im wesentlichen horizontal und führt die Sitzfläche 2 am Gestell 1. Eine weitere Führungsschiene Y führt den hinteren Bereich der Sitzfläche 2 und die vordere RUckenplatte 4. Eine weitere Führungsscheine Z verläuft im Bereich eines Gelenks C der vorderen Rückenplatte 4 und führt diese an der Rückenlehne 3.The novel seating furniture consists of a frame 1, a seat 2, a backrest 3 and a front back plate 4 located on the front of the backrest. A guide rail X runs essentially horizontally and guides the seat surface 2 on the frame 1. Another guide rail Y guides the rear area of the seat 2 and the front back plate 4. A further guide plate Z runs in the area of a joint C of the front back plate 4 and guides it on the backrest 3.

Eine Zugfeder 5 verbindet das Gestell mit einem Gelenk A, welches den unteren Teil der Rückenlehne 3 mit dem hinteren Teil der Sitzfläche 2 verbindet. An diesem Gelenk A greift weiterhin ein Steg 6 an, dessen anderes Ende an einem Gelenk D am unteren Teil der vorderen Rückenplatte 4 befestigt ist. In der Ausgangslage (vgl. Figur 1) bildet der Steg 6 mit dem unteren Teil der vorderen Rüeksnplatte in etwa einen rechten Winkel.A tension spring 5 connects the frame with a joint A, which connects the lower part of the backrest 3 with the rear part of the seat 2. At this joint A, a web 6 also acts, the other end of which is attached to a joint D on the lower part of the front back plate 4. In the starting position (cf. FIG. 1), the web 6 forms approximately a right angle with the lower part of the front rear panel.

Die vordere Rückenplatte besteht somit aus meheren Teilen, nämlich einem unteren Teil 7, der zwischen eines Gelenk E und der Gelenk C ausgebildet ist. Das Gelenk E ist an der unteren Kante der vorderen Rückenplatte ausgebildet und wird längs der Führung Y geführt. Außerdem besteht die vordere RUckenplatte aus einen mittleren Teil 8 und sinem oder mehreren oberen Teilen 9, die voneinander über sis eder mehrere Gelenke G verbunden sind. Der obere Teil 9 ist vorgesehen,wenn das Sitzmöbel eine Kepfatütze hat.The front back plate thus consists of several parts, namely a lower part 7, which is formed between a joint E and the joint C. The hinge E is formed on the lower edge of the front back plate and is guided along the guide Y. In addition, the front back plate consists of a central part 8 and one or more upper parts 9, which are connected to one another by means of several joints G. The upper part 9 is provided when the seating has a kepfa support.

Ebenfalls in diesen Fall ist die hintere Rückenlehne 3 in einem oberen Teil 13 fortgesetzt, der an der hinteren Rückenlehne 3 über ein Gelenk P angelenkt ist.In this case, too, the rear backrest 3 is continued in an upper part 13, which is articulated on the rear backrest 3 via a joint P.

Es sind in den Figuren außerdem poletertuigen 10 fUr die Sitzfläche und 11 für die Rückenlehne mit Rüakenplatte angedeutet. Wird durch die Körperbewegung einer auf dem Sitzmöbel sitzenden Person die Sitzfläche 2 mit deren Polster 10 in Pfeilrichtung 12 nach vorne gezogen, so verschiebt sich das Gelenk A von Figur 1 zum Ort Δ1 von Figur 2. Die Feder 5 wird ausgedehnt. Dedurch dreht sich die hintere Rückenlehne 3 um das Gelenk B, mit dem sie am Gestell 1 angelenkt ist. Der Winkel alpha zwischen der Sitzfläche 2 und der hinteren Rückenlehne 3 vergrößert sich. Bei konstanten Abständen zwischen den Gelenken A - D und D - E muß sich bei einer Vergrößerung dieses Winkels alpha das Gelenk E nach E1 (Figur 2) bewegen. Dadurch bewegen sich zwangsläufig die Gelenke C nach C1 und D nach D1. Es entsteht hierbei eine kontinuierliche Unterstützung des Lendenwirbelbereichs mittels des unteren Teiles 7, der nachgeführt wird.The figures also show poletertuigen 10 for the seat and 11 for the backrest with Rüakenplatte. If the seat surface 2 with its cushion 10 is pulled forward in the direction of the arrow 12 by the body movement of a person sitting on the seating furniture, the joint A of FIG. 1 shifts to the location Δ1 of FIG. 2. The spring 5 is expanded. As a result, the rear backrest 3 rotates about the joint B with which it is articulated on the frame 1. The angle alpha between the seat 2 and the backrest 3 increases. With constant distances between the joints A - D and D - E If this angle alpha is increased, the joint E must move to E1 (FIG. 2). This inevitably moves the joints C to C1 and D to D1. This creates a continuous support of the lumbar region by means of the lower part 7, which is tracked.

Durch einen zeichnerisch nicht dargestellten Zug in Form eines Stahlbandes, das mit dem obersten Teil 13 der hinteren Rückenlehne 3 einerseits und mit der Sitzfläche 2 andererseits verbunden ist, wird bei der Bewegung eine kontinuierliche Unterstützung im Kopfbereich erreicht, der hierbei seine Lage relativ zum Gestell 1 im wesentlichen beibehält.Through a train, not shown in the drawing, in the form of a steel band, which is connected to the uppermost part 13 of the rear backrest 3 on the one hand and to the seat surface 2 on the other hand, continuous support in the head area is achieved during the movement, which position is relative to the frame 1 essentially maintains.

Die beschriebene Bewegung läßt sich vor und zurück nur durch eine entsprechende Körperbewegung erzielen, und zwar ohne Betätigung von Hebeln oder Knöpfen. Eventuell vorhandene Armlehnen werden in die beschriebene Konstruktion nicht einbezogen, weil die Rückenlehne 3 Über das Gelenk B am Gestell 1 schwenkbar gelagert ist. Die Armlehnen brauehen vielmehr lediglich in üblicher Weise mit dem Gestell 1 verbunden zu werden.The movement described back and forth can only be achieved by a corresponding body movement, and that without actuating levers or buttons. Possibly existing armrests are not included in the construction described because the backrest 3 is pivotably mounted on the frame 1 via the joint B. Rather, the armrests only need to be connected to the frame 1 in the usual way.

Der Federzug 5 hält das Sitzmöbel in unbesessenem Zustand in der in Figur 1 gezeigten aufrechten Position.The spring balancer 5 holds the seating furniture in the upright position shown in FIG.

Falls ein Bezug vorhanden ist, ist dessen rückseitiger Teil in Querpfeifen abgesteppt und senkrecht dazu mit Gummibändern versehen oder sonstwie zumindest in Richtung des Pfeils 12 (Bewegungsrichtung) elastisch ausgebildet.If there is a cover, the rear part of it is quilted in cross pipes and provided with rubber bands perpendicular to it, or is at least elastic in the direction of arrow 12 (direction of movement).
