Description

Die Erfindung betrifft ein Sitzmöbel mit einem Gestell mit einer Führung, die eine im wesentlichen horizontale Verschiebung einer Sitzfläche relativ zum Gestell ermöglicht, ferner mit einer am Gestell um eine horizontale Achse schwenkbaren Rückenlehne, wobei an das rückwärtige Ende der Sitzfläche eine Stütze angelenkt ist, die sich an der dem Benutzer des Sitzmöbels zugewandten Seite der Rückenlehne befindet derart, daß bei einer Verschiebung der Sitzfläche, ausgehend von einer rückwärtigen Ausgangslage der Sitzfläche nach vorne die Stütze im Lendenwirbelbereich des Benutzers diesen Bereich unterstützend ebenfalls nach vorne bewegt wird, bzw. umgekehrt.The invention relates to a piece of furniture with a frame with a guide that enables a substantially horizontal displacement of a seat relative to the frame, further with a pivotable on the frame about a horizontal axis backrest, wherein a support is articulated to the rear end of the seat, the is located on the side of the backrest facing the user of the seating furniture in such a way that when the seat is moved forward, starting from a rear starting position of the seat, the support in the lumbar region of the user is also moved to support this area, or vice versa.

Ein solches Sitzmöbel beschreibt die GB-A-1 056 648. An den Seiten der Sitzfläche sind dort Stangen befestigt, deren rückwärtige Enden nach oben gebogen sind. Die oberen Enden dieser Abbiegungen sind gelenkig mit Teleskoprohren verbunden, deren andere Enden etwa im Nackenbereich der Rückenlehne an Stangen angelenkt sind, die die Rückenlehne versteifen. Von der rückwärtigen Ausgangslage ausgehend kann daher der Benutzer dieses Sitzmöbels die Sitzfläche in etwa horizontal nach vorne verschieben, wobei sein Lendenwirbelbereich bei dieser Bewegung über die Teleskoprohre mit der auf ihnen aufliegenden Polsterung ständig gestützt wird. Über die rückwärtige Ausgangslage hinaus, die etwa der aufrechten Sitzposition entspricht, kann die Rückenlehne aber nicht nach hinten verschwenkt werden. Auch ist es nachteilig, daß der Rücken und insbesondere der Lendenwirbelbereich des Benutzers nur durch die beiden seitlichen Teleskoprohre mit ihrer Polsterung gestützt werden. Die in diesem Bereich auf die Polsterung in der nach vorne geschobenen Lage der Sitzfläche einwirkenden Kräfte führen somit dazu, daß die Polsterung verhältnismäßig rasch ermüdet und daher dem Benutzer nicht mehr die optimale Unterstützung im Lendenwirbelbereich bietet. Auch fällt nachteilig ins Gewicht, daß bei der erwähnten Verschiebung der Sitzfläche mit Stütze des Lendenwirbelbereichs sich die Länge der Teleskoprohre notwendigerweise verändert, wodurch wiederum die Polsterung im Bereich der Teleskoprohre beschädigt werden kann, wenn hierfür nicht besondere Vorkehrungen getroffen werden. Auch ist dort keine Vorsorge dafür getroffen, um die bei der erwähnten Verschiebung auftretenden Längenänderungen der Polsterung im Lendenwirbelbereich aufzunehmen. Alle diese Merkmale verkürzen notwendigerweise die Lebensdauer dieses bekannten Sitzmöbels.GB-A-1 056 648 describes such seating. Bars are attached to the sides of the seat, the rear ends of which are bent upwards. The upper ends of these bends are articulated with telescopic tubes, the other ends of which are articulated in the neck region of the backrest on rods which stiffen the backrest. Starting from the rear starting position, the user of this piece of seating furniture can therefore move the seat surface approximately horizontally to the front, his lumbar vertebra area being constantly supported during this movement via the telescopic tubes with the upholstery resting on them. Beyond the rear starting position, which corresponds approximately to the upright sitting position, the backrest cannot be pivoted backwards. It is also disadvantageous that the back and in particular the lumbar region of the user are supported only by the two lateral telescopic tubes with their padding. The forces acting in this area on the upholstery in the forward-shifted position of the seat surface therefore result in the upholstery becoming tired relatively quickly and therefore no longer offering the user optimal support in the lumbar region. It is also disadvantageous that the length of the telescopic tubes necessarily changes when the seat surface is supported with support of the lumbar region, which in turn can damage the upholstery in the region of the telescopic tubes unless special precautions are taken for this. There is also no provision there to accommodate the changes in length of the upholstery in the lumbar region that occur during the aforementioned displacement. All of these features necessarily shorten the lifespan of this known seating.

Die FR-A-1 301 578 beschreibt einen Stuhl, dessen Sitzfläche in horizontaler Richtung am Gestell verschiebbar ist. An das hintere Ende der Sitzfläche ist dessen Rückenlehne angelenkt, die ihrerseits etwa in ihrem mittleren Bereich an das Gestell angelenkt ist. Eine Feder greift einerseits am rückwärtigen Bereich der Sitzfläche und andererseits am Gestell an und zieht die Sitzfläche mit Rückenlehne in eine aufrechte Ausgangslage.FR-A-1 301 578 describes a chair, the seat of which can be displaced in the horizontal direction on the frame. At the rear end of the seat, the backrest is articulated, which in turn is articulated to the frame approximately in its central region. A spring engages the back of the seat and the frame and pulls the seat and backrest into an upright starting position.

Nachteilig ist es hierbei insbesondere, daß bei der erwähnten Verschiebung der Sitzfläche mit der an ihr angelenkten Rückenlehne der Lendenwirbelbereich einer auf dem Stuhl sitzenden Person nicht unterstützt wird.It is particularly disadvantageous here that the lumbar vertebra area of a person sitting on the chair is not supported when the seat surface is displaced with the backrest articulated to it.

Die DE-A-2644412 beschreibt ein Sitzmöbel mit einer Sitzfläche und einer an den rückwärtigen Teil der Sitzfläche angelenkten Rückenlehne, wobei das gemeinsame Gelenk über einen Lenker an das Gestell des Sitzmöbels angelenkt ist. Über einen weiteren Lenker kann die Sitzfläche flach an der Rückenlehne anliegend hochgeklappt werden. Auch dieses Sitzmöbel unterstützt daher nicht ausreichend den Lendenwirbelbereich einer auf ihm sitzenden Person.DE-A-2644412 describes a piece of seating furniture with a seat surface and a backrest articulated to the rear part of the seat surface, the common joint being articulated via a handlebar to the frame of the seat furniture. The seat can be folded up flat against the backrest using another handlebar. This seating furniture therefore does not adequately support the lumbar region of a person sitting on it.

Ein ähnliches Sitzmöbel beschreibt die FR-A-2088851, bei dem allerdings die Sitzfläche und die Rückenlehne starr miteinander verbunden sind. Sie sind über ein Lenkerpaar am Gestell schwenkbar befestigt. Im vorderen Bereich des Gestells ist außerdem eine Führung für eine horizontale Verschiebung der Sitzfläche mit Rückenlehne relativ zum Gestell vorgesehen.A similar piece of seating furniture is described in FR-A-2088851, in which, however, the seat surface and the backrest are rigidly connected to one another. They are pivotally attached to the frame via a pair of handlebars. In the front area of the frame, a guide is also provided for a horizontal displacement of the seat with backrest relative to the frame.

Die FR-A-1 493433 beschreibt ein Sitzmcbet mit einer Sitzfläche und einer daran angelenkten Rückenlehne, die beide am Gestell des Sitzmöbels geführt sind derart, daß bei einer horizontalen Verschiebung der Sitzfläche nach vorne bzw. hinten die Rückenlehne ihre Neigung relativ zum Gestell verändert. Eine Feder zieht die Sitzfläche und damit die mit ihr verbundene Rückenlehne in die aufrechte Ausgangslage. Auch bei diesem bekannten Sitzmöbel wird der Lendenwirbelbereich einer auf ihm sitzenden Person nicht unterstützt, weil nämlich die Rückenlehne als ebene Platte ausgebildet ist.FR-A-1 493433 describes a seat with a seat surface and a backrest articulated thereon, both of which are guided on the frame of the seating furniture in such a way that the backrest changes its inclination relative to the frame when the seat surface is horizontally displaced forwards or backwards. A spring pulls the seat and thus the backrest connected to it into the upright starting position. Also in this known seating furniture, the lumbar region of a person sitting on it is not supported because the backrest is designed as a flat plate.

Der Erfindung liegt die Aufgabe zugrunde, ein Sitzmöbel der eingangs genannten Art dahingehend auszugestalten, daß der Benutzer bei Beibehaltung der vorteilhaften Unterstützung seines Lendenwirbelbereichs sich ausgehend von der rückwärtigen Ausgangslage des Sitzmöbels bequem noch weiter zurücklehnen kann, wobei dann die Neigung der Rückenlehne zur Horizontalen noch weiter abgeflacht wird und gleichzeitig die Sitzfläche weiter nach vorne verschoben wird. Bei der Verschiebung der Sitzfläche und der dazu gleichzeitig erfolgenden Verschwenkung der Rückenlehne sollen keinerlei Kräfte von der Rückenlehne auf den Rücken des Benutzers bzw. seine Kleidung ausgeübt werden. Außerdem soll sich das Sitzmöbel nach der Erfindung durch eine hohe Lebensdauer auszeichnen.The invention has for its object to provide seating of the type mentioned in such a way that the user can comfortably lean back even further while maintaining the advantageous support of his lumbar region, starting from the rear initial position of the seating furniture, with the inclination of the backrest to the horizontal even further is flattened and at the same time the seat is moved further forward. When the seat is moved and the backrest is pivoted at the same time, no forces should be exerted from the backrest onto the back of the user or his clothing. In addition, the seating furniture according to the invention should have a long service life.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Rückenlehne gelenkig mit der Sitzfläche verbunden ist und um die horizontale Achse ausgehend von der rückwäritigen Ausgangslage auch nach hinten verschwenkt werden kann, daß die Stütze als Stützplatte ausgebildet ist, deren unteres Ende an die Sitzfläche angelenkt ist, daß die Stützplatte durch ein weiteres Gelenk in eine obere Teilplatte und eine untere Teilplatte unterteilt ist, von denen die untere Teilplatte die Unterstützung des Lendenwirbelbereichs des Benutzers bewirkt, und daß die Stützplatte an der Rückenlehne relativ zu dieser geführt verschiebbar ist.To achieve this object, the invention is characterized in that the backrest is articulated to the seat and around the horizontal axis can also be pivoted backwards, starting from the rearward starting position, that the support is designed as a support plate, the lower end of which is articulated to the seat surface, that the support plate is divided by an additional joint into an upper partial plate and a lower partial plate, of which the lower part of the plate supports the lumbar region of the user, and that the support plate on the backrest is displaceable relative to this.

Durch diese Merkmale wird erreicht, daß bei der Verschiebung der Sitzfläche und der damit verbundenen Verschwenkung der Rückenlehne die Stützplatte am Rücken des Benutzers anliegt und hierbei in allen Positionen dessen Lendenwirbelbereich unterstützt, ohne daß dabei fühlbare Relativbewegungen zwischen der Stützplatte bzw. ihrer Polsterung und dem Benutzer auftreten. Diese Relativbewegungen erfolgen vielmehr zwischen der Stützplatte und der Rückenlehne. Die untere Teilplatte bewirkt hierbei die ständige Unterstützung des Lendenwirbelbereichs.These features ensure that the displacement of the seat and the associated pivoting of the backrest rests on the support plate on the user's back and thereby supports the lumbar region in all positions without any noticeable relative movements between the support plate or its upholstery and the user occur. Rather, these relative movements take place between the support plate and the backrest. The lower part of the plate provides constant support for the lumbar region.

Es dient einer Erleichterung der Verschiebungsbewegung bei gleichzeitig guter Führung der Stützplatte, wenn die Führung der Stützplatte an der Rückenlehne im Bereich des weiteren Gelenks der Stützplatte ausgebildet ist.It serves to facilitate the displacement movement with good guidance of the support plate if the support plate is guided on the backrest in the region of the further joint of the support plate.

Bei der erwähnten Verschiebung verschiebt sich auch die Stützplatte zusammen mit der Sitzfläche nach vorn bzw. hinten. In diesem Zusammenhang dient es einer fühlbaren Verbesserung der Führung der unteren Teilplatte, wenn ein Steg vorgesehen ist, der das Gelenk zwischen der Sitzfläche und der Rückenlehne mit der unteren Teilplatte gelenkig verbindet.In the aforementioned shift, the support plate also moves forward and backward together with the seat. In this context, there is a noticeable improvement in the guidance of the lower partial plate if a web is provided which articulates the joint between the seat surface and the backrest with the lower partial plate.

Die hierbei aufzubringenden Kräfte sind besonders gering, wenn der Steg mit der unteren Teilplatte in der Ausgangslage des Sitzmöbels einen etwa rechten Winkel bildet, wie es ebenfalls bevorzugt wird.The forces to be exerted here are particularly low if the web forms an approximately right angle with the lower partial plate in the starting position of the seating furniture, as is also preferred.

Eine Feder kann das Gestell mit der Sitzfläche verbinden, die die Sitzfläche in die Ausgangslage zieht.A spring can connect the frame to the seat, which pulls the seat into the starting position.

Falls das Sitzmöbel nach der Erfindung eine Kopfstütze hat, so wird es bevorzugt, daß dessen Neigung ebenfalls nachgeführt wird. Hierzu sind die Rückenlehne und die obere Teilplatte im Nackenbereich gelenkig ausgebildet, wobei ein Band die Sitzfläche mit der schwenkbaren oberen Teilplatte der Rückenlehne verbindet. Das Band ist beispielsweise als Stahlband ausgebildet. Bei der Verschiebung der Sitzfläche nach vorn zieht das Band, welches vorzugsweise an beiden Seiten des Sitzmöbels angebracht ist, den obersten Teil der Rückenlehne ebenfalls nach vorn, so daß die im wesentlichen lotrechte Anordnung der Kopfstütze bei der Verschiebung im wesentlichen beibehalten bleibt. Die hierbei erfolgende Verschwenkung des obersten Teils der Rückenlehne wird auch der oberen Teilplatte der Stützplatte mitgeteilt, die zu diesem Zweck an das nach unten anschließende Teil der Stützplatte angelenkt ist.If the seating furniture according to the invention has a headrest, it is preferred that its inclination is also adjusted. For this purpose, the backrest and the upper partial plate are articulated in the neck area, a band connecting the seat surface to the pivotable upper partial plate of the backrest. The band is designed for example as a steel band. When moving the seat forward, the band, which is preferably attached to both sides of the seating furniture, also pulls the uppermost part of the backrest forward, so that the substantially vertical arrangement of the headrest remains essentially unchanged during the displacement. The pivoting of the uppermost part of the backrest that is carried out in this case is also communicated to the upper partial plate of the support plate, which for this purpose is articulated to the part of the support plate which adjoins downwards.

Falls der rückwärtige Teil eines die Sitzfläche, die Rückenlehne mit Stützplatte sowie deren Polsterungen umschließenden Bezuges elastisch ausgebildet ist, werden die beim Verschieben bzw. Verschwenken am Bezug auftretenden Kräfte besonders gut aufgenommen.If the rear part of a cover surrounding the seat, the backrest with the support plate and the upholstery thereof is elastic, the forces occurring when the cover is moved or pivoted are absorbed particularly well.

Bevorzugt wird es außerdem, wenn die Rückenlehne an einer rückwärtigen, nach oben weisenden Verlängerung des Gestells schwenkbar gelagert ist. Die beschriebene Konstruktion wird hierdurch unabhängig von gegebenenfalls vorhandenen Armlehnen, was für viele Anwendungsfälle vorteilhaft ist.It is also preferred if the backrest is pivotally mounted on a rearward, upward extension of the frame. The construction described is thereby independent of any armrests that may be present, which is advantageous for many applications.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert. Es zeigt

  • Fig. 1 die schematisch wesentlichen Bauelemente eines neuartigen Sitzmöbels in einer Seitenansicht, und zwar in der rückwärtigen Ausgangsstellung des Sitzmöbels,
  • Fig. 2 die Situation von Fig. 1 in der nach vorn verschobenen Stellung der Sitzfläche mit flacher, geneigter Rückenlehne.
The invention is explained in more detail below using an exemplary embodiment. It shows
  • 1 shows the schematically essential components of a new type of seating furniture in a side view, specifically in the rear initial position of the seating furniture,
  • Fig. 2 shows the situation of Fig. 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.An armchair provided with a headrest and without armrests is shown in the drawing. The principles described can equally well be applied to a chair or other seating furniture, 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, einer Rückenlehne 3 und einer an der Vorderseite der Rückenlehne befindlichen vorderen Stützplatte 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 Stützplatte 4. Eine weitere Führungsschiene Z verläuft im Bereich eines Gelenks C der vorderen Stützplatte 4 und führt diese an der Rückenlehne 3.The novel seating consists of a frame 1, a seat 2, a backrest 3 and a front support 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 surface 2 and the front support plate 4. A further guide rail Z runs in the area of a joint C of the front support plate 4 and guides it on the backrest 3.

Eine Zugfeder 5 verbindet das Gestell mit dem 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 Stützplatte 4 befestigt ist. In der Ausgangslage (vgl. Fig. 1) bildet der Steg 6 mit dem unteren Teil der vorderen Stützplatte in etwa einen rechten Winkel.A tension spring 5 connects the frame to the joint A, which connects the lower part of the backrest 3 to 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 at the lower part of the front support plate 4. In the starting position (cf. FIG. 1), the web 6 forms approximately a right angle with the lower part of the front support plate.

Die vordere Stützplatte besteht somit aus mehreren Teilen, nämlich einer unteren Teilplatte 7, die zwischen einem Gelenk E und dem Gelenk C ausgebildet ist. Das Gelenk E ist an der unteren Kante der vorderen Stützplatte ausgebildet und wird längs der Führung Y geführt. Außerdem besteht die vordere Stützplatte aus einer oberen Teilplatte 8 und einer oder mehreren weiteren oberen Teilplatten 9, die mit einander über ein oder mehrere Gelenke G verbunden sind. Die obere Teilplatte 9 ist vorgesehen, wenn das Sitzmöbel eine Kopfstütze hat. In diesem Fall ist die Rückenlehne 3 in einem oberen Teil 13 fortgesetzt, das an der Rückenlehne 3 über ein Gelenk F angelenkt ist.The front support plate thus consists of several parts, namely a lower part plate 7, which is formed between a joint E and the joint C. The hinge E is formed on the lower edge of the front support plate and is guided along the guide Y. In addition, the front support plate consists of an upper partial plate 8 and one or more further upper partial plates 9, which are connected to one another via one or more joints G. The upper partial plate 9 is provided when the seating furniture has a headrest. In this case, the backrest is 3 in an upper part 13 continued, which is articulated on the backrest 3 via a joint F.

Es sind in den Figuren außerdem eine Polsterung 10 für die Sitzfläche 2 und eine Polsterung 11 für die Rückenlehne mit Stützplatte angedeutet.In the figures, padding 10 for the seat surface 2 and padding 11 for the backrest with a support plate are also indicated.

Wird durch die Körperbewegung einer auf dem Sitzmöbel sitzenden Person die Sitzfläche 2 mit deren Polsterung 10 in Pfeilrichtung 12 nach vorn gezogen, so verschiebt sich das Gelenk A von Fig. 1 zum Ort A1 von Fig. 2. Die Feder 5 wird hierbei gedehnt. Dadurch schwenkt die Rückenlehne 3 um eine Achse B, mit der sie am Gestell 1 angelenkt ist. Der Winkel lX zwischen der Sitzfläche 2 und der Rückenlehne 3 vergrößert sich dabei. Bei konstanten Abständen zwischen den Gelenken A - D und D - E muß sich bei einer Vergrößerung des Winkels α das Gelenk E nach E1 (Fig. 2) bewegen. Dadurch bewegen sich zwangsläufig die Gelenke C nach C1 und D nach D1. Es entsteht hierbei eine kontinuierliche Unterstützung des Lendenwirbelbereichs mittels der unteren Teilplatte 7, die nachgeführt wird.If the seat surface 2 with its padding 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 moves to the location A1 of FIG. 2. The spring 5 is stretched in the process. As a result, the backrest 3 pivots about an axis B with which it is articulated on the frame 1. The angle lX between the seat 2 and the backrest 3 increases. At constant distances between the joints A - D and D - E, the joint E must move to E1 (FIG. 2) when the angle α is increased. 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 plate 7, which is adjusted.

Durch einen zeichnerisch nicht dargestellten Zug in Form eines Stahlbandes, das mit dem obersten Teil 13 der Rückenlehne 3 einerseits und mit der Sitzfläche 2 andererseits verbunden ist, wird bei der beschriebenen 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 strip, which is connected to the uppermost part 13 of the backrest 3 on the one hand and to the seat surface 2 on the other hand, continuous support in the head region is achieved during the movement described, which position is relative to the frame 1 essentially maintains.

Die beschriebene Bewegung läßt sich vor und zurück 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 die Achse B am Gestell 1 schwenkbar gelagert ist. Armlehnen brauchen vielmehr lediglich in üblicher Weise mit dem Gestell 1 verbunden zu werden.The movement described can be achieved back and forth by a corresponding movement of the body, without the use of levers or buttons. Possibly existing armrests are not included in the construction described, because the backrest 3 is pivotally mounted on the frame 1 via the axis B. Armrests only need to be connected to the frame 1 in the usual way.

Der Zug der Feder 5 hält das Sitzmöbel in unbelastetem Zustand in der in Fig. 1 gezeigten aufrechten Position.The tension of the spring 5 holds the seating furniture in the unloaded state in the upright position shown in FIG. 1.

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).
