Description

Die Erfindung betrifft ein Sitzmöbel, insbesondere ein Sofa oder einen Sessel, mit einem Sitzteil und einem Rückenteil.The invention relates to a chair, in particular a sofa or a chair, with a seat part and a back part.

Derartige Sitzmöbel werden häufig so ausgestaltet, dass die Sitztiefe oder die Lehnenhöhe des Rückenteils variabel ist, um eine Anpassung an die Körpergröße des Benutzers oder eine von diesem gewünschte Sitzposition zu ermöglichen.Such seating is often designed so that the seat depth or the backrest height of the back part is variable to allow adjustment to the size of the user or a desired seat position of this.

In GB 189 885 A ist ein Sitzmöbel offenbart, dessen Lehne zur Verstellung der Lehnenneigung mit der verschiebbaren Sitzfläche gekoppelt ist.In GB 189 885 A is disclosed a chair whose backrest is coupled to adjust the backrest inclination with the sliding seat.

Aufgabe der vorliegenden Erfindung ist es, ein Sitzmöbel zu schaffen, bei dem die Sitztiefe und die Lehnenhöhe veränderbar sind, wobei eine einfache und komfortable Bedienung gewährleistet sein soll.Object of the present invention is to provide a chair in which the seat depth and the backrest height can be changed, with a simple and comfortable operation should be guaranteed.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst und insbesondere durch ein Sitzmöbel, insbesondere Sofa oder Sessel, mit einem zur Verstellung der Sitztiefe bewegbaren, insbesondere verschiebbaren Sitzteil und einem zur Verstellung der Lehnenhöhe bewegbaren, insbesondere verschiebbaren, Rückenteil, welche derart miteinander gekoppelt sind, dass eine Bewegung des Rückenteils eine Bewegung des Sitzteils bewirkt, und/oder umgekehrt.The object is solved by the features of claim 1 and in particular by a chair, in particular sofa or armchair, with a movable seat cover for adjusting the seat depth, in particular sliding seat part and a movable to adjust the backrest height, in particular displaceable, back part, which are coupled together in that a movement of the back part causes a movement of the seat part, and / or vice versa.

Das erfindungsgemäße Sitzmöbel erlaubt also sowohl eine Verstellung der Sitztiefe als auch eine Verstellung der Lehnenhöhe, wodurch eine besonders individuelle Anpassung der Sitzposition ermöglicht wird. Zugleich wird durch die Kopplung von Sitzteil und Rückenteil eine besonders einfache Bedienung erreicht, da der Benutzer lediglich ein Teil in seiner Position verstellen muss und damit gleichzeitig eine Verstellung des anderen Teils bewirkt.The seating invention thus allows both an adjustment of the seat depth and an adjustment of the backrest height, creating a particularly individual adjustment of the seating position is possible. At the same time a particularly simple operation is achieved by the coupling of seat part and back part, since the user only a part in its position must adjust and thus simultaneously causes an adjustment of the other part.

Gemäß einer bevorzugten Ausführungsform bewirkt eine Vergrößerung der Lehnenhöhe eine Vergrößerung oder Verminderung der Sitztiefe. Wird also die Höhe des Rückenteils vergrößert, vergrößert sich bei einer ersten Variante gleichzeitig die Sitztiefe, während sie sich bei einer zweiten Variante vermindert. Bei einer Verminderung der Lehnenhöhe vermindert sich gemäß der ersten Variante die Sitztiefe, während sie sich bei der zweiten Variante entsprechend vergrößert. Auf analoge Weise kann eine Veränderung der Lehnenhöhe erfolgen, wenn das Sitzteil verstellt wird.According to a preferred embodiment, an increase in the backrest height causes an increase or decrease in the seat depth. Thus, if the height of the back part is increased, increases in a first variant at the same time the seat depth, while it decreases in a second variant. With a reduction of the backrest height decreases according to the first variant, the seat depth, while correspondingly increased in the second variant. In a similar manner, a change in the backrest height can be done when the seat part is adjusted.

Bevorzugt sind das Sitzteil und das Rückenteil durch Hebel, insbesondere Gelenkhebel, miteinander gekoppelt. Hierdurch lässt sich auf einfache und zuverlässige Weise eine Kopplung der beiden Teile herstellen.The seat part and the back part are preferably coupled to one another by levers, in particular articulated levers. This makes it possible to produce a coupling of the two parts in a simple and reliable manner.

Gemäß einer bevorzugten Ausführungsform ist zumindest ein Kraftspeicher, insbesondere eine Feder oder eine Gasdruckfeder, zur Unterstützung der Bewegung des Sitzteils und/oder des Rückenteils vorgesehen. Hierdurch erhöht sich der Bedienkomfort, da die vom Benutzer für die Verstellung aufzuwendende Kraft zumindest in einer Richtung reduziert wird.According to a preferred embodiment, at least one energy accumulator, in particular a spring or a gas pressure spring, is provided to support the movement of the seat part and / or the back part. This increases the ease of use, as the expended by the user for the adjustment force is reduced at least in one direction.

Bevorzugt ist, wenn der Kraftspeicher zur Unterstützung der Vergrößerung der Sitztiefe und/oder der Lehnenhöhe ausgebildet ist. Dadurch wird der Kraftaufwand beim Herausziehen des Sitzteils bzw. des Rückenteils verringert, da diese Bewegung erfahrungsgemäß etwas schwieriger zu bewerkstelligen ist als das Hineinschieben, bei dem der Benutzer sein Körpergewicht einsetzen kann.It is preferred if the energy storage device is designed to support the increase in the seat depth and / or the backrest height. As a result, the force required to pull out the seat part or the back part is reduced, since experience has shown that this movement is somewhat more difficult to accomplish than pushing in, in which the user can use his body weight.

Gemäß einer vorteilhaften Ausführungsform ist der Kraftspeicher ein Bestandteil einer nach dem Prinzip eines Kniehebels ausgebildeten Anordnung. Hierdurch können das Sitzteil bzw. das Rückenteil ohne zusätzliche Fixiermittel auch in der Endstellung festgelegt werden, in der der Kraftspeicher vorgespannt ist, ohne dass es zusätzlicher Feststellmittel bedarf.According to an advantageous embodiment of the energy storage is part of a trained on the principle of a toggle lever assembly. As a result, the seat part or the back part can be fixed without additional fixing in the final position in which the energy storage is biased without the need for additional locking means.

Weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen, der Beschreibung sowie der Zeichnung angegeben.Further advantageous embodiments are specified in the dependent claims, the description and the drawings.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels mit Bezug auf die Zeichnungen erläutert. In diesen zeigt:

The invention will be explained below with reference to an embodiment with reference to the drawings. In these shows:
Fig. 1
a sectional view of a seat according to the invention furniture in a first adjustment position; and
Fig. 2
a sectional view of the chair of Fig. 1 in a second adjustment position.

Fig. 1 und 2 zeigen ein Sitzmöbel 10 mit einem Grundkörper 12, an dem ein gepolstertes Sitzteil 14 mittels einer Sitzteilführung 16 horizontal verschiebbar angeordnet ist. Fig. 1 and 2 show a chair 10 with a base 12, on which a padded seat part 14 is arranged horizontally displaceable by means of a seat part guide 16.

An dem Grundkörper 12 ist weiterhin ein ebenfalls gepolstertes, als Rückenlehne dienendes Rückenteil 18 mittels einer Rückenteilführung 20 in nahezu vertikaler bzw. leicht nach hinten geneigter Richtung verschiebbar angeordnet.On the main body 12, a likewise padded, serving as a backrest back portion 18 is further arranged by means of a back part guide 20 in a nearly vertical or slightly inclined backwards direction.

Sitzteil 14 und Rückenteil 18 sind mittels einer nachfolgend noch näher erläuterten Hebelanordnung 22 derart gekoppelt, dass entsprechend der Pfeile in Fig. 1 eine Vergrößerung der Lehnenhöhe, d.h. des Abstands zwischen der Sitzfläche des Sitzteils 14 und der Oberkante des Rückenteils 18, durch Verschieben des Rückenteils 18 nach oben eine Verschiebung des Sitzteils 14 nach links bewirkt, wodurch sich die Sitztiefe, d.h. der Abstand zwischen der Lehnenfläche des Rückenteils 18 und der Vorderkante des Sitzteils 14, ebenfalls vergrößert. Die resultierende End- oder Ausziehposition ist in Fig. 2 dargestellt.Seat part 14 and back part 18 are coupled by means of a lever arrangement 22, which will be explained in more detail below, in such a way that according to the arrows in FIG Fig. 1 an increase in the backrest height, ie the distance between the seat surface of the seat portion 14 and the upper edge of the back portion 18, by displacement of the back portion 18 upwards causes displacement of the seat portion 14 to the left, causing the seat depth, ie the distance between the back surface of the back portion 18 and the front edge of the seat portion 14, also enlarged. The resulting end or extension position is in Fig. 2 shown.

Umgekehrt bewirkt ein Verschieben des herausgezogenen Rückenteils 18 nach unten eine Verminderung der Lehnenhöhe und gleichzeitig auch eine Verminderung der Sitztiefe, da das Sitzteil 14 durch die Hebelanordnung 22 nach rechts zurück in die Grundposition verschoben wird. Die entsprechenden Verschiebebewegungen sind durch die Pfeile in Fig. 2 angedeutet.Conversely, a displacement of the pulled-back portion 18 downward causes a reduction of the backrest height and at the same time a reduction of the seat depth, since the seat part 14 is moved by the lever assembly 22 to the right back to the home position. The corresponding displacement movements are indicated by the arrows in Fig. 2 indicated.

Um den in der Ausziehposition gemäß Fig. 2 vorhandenen Spalt zwischen Sitzteil 14 und Rückenteil 18 abzudecken, ist ein gepolstertes Zwischenteil 24 vorgesehen, das über ein Halteelement 26 an dem Grundkörper 12 befestigt ist.To the in the pull-out position according to Fig. 2 Cover existing gap between the seat part 14 and the back part 18, a padded intermediate part 24 is provided, which is fastened via a holding element 26 to the base body 12.

Die Hebelanordnung 22 umfasst einen ersten Hebelarm 30, welcher mit seinem einen Ende an einem Drehpunkt 28 schwenkbar an dem Grundkörper 12 gelagert ist. Ein zweiter Hebelarm 32 ist an dem anderen Ende des ersten Hebelarms 30 und an dem Sitzteil 14 angelenkt.The lever arrangement 22 comprises a first lever arm 30 which is pivotably mounted with its one end at a pivot point 28 on the base body 12. A second lever arm 32 is hinged to the other end of the first lever arm 30 and to the seat part 14.

Ein dritter Hebelarm 34 ist unter Ausbildung eines annähernd rechten Winkels drehfest mit dem ersten Hebelarm 30 gekoppelt. Ein vierter Hebelarm 36 ist an dem freien Ende des dritten Hebelarms 34 und an dem Rückenteil 18 angelenkt.A third lever arm 34 is rotatably coupled to form the first lever arm 30 to form an approximately right angle. A fourth lever arm 36 is hinged to the free end of the third lever arm 34 and to the back member 18.

Ein fünfter Hebelarm 38 ist drehfest mit dem ersten Hebelarm 30 gekoppelt, und zwar an der gleichen Stelle wie der dritte Hebelarm 34. Eine Gasdruckfeder 40 ist mit ihrem einen Ende an dem Grundkörper 12 unterhalb des Sitzteils 14 und mit ihrem anderen Ende an dem freien Ende des fünften Hebelarms 38 angelenkt. Fig. 1 zeigt die Gasdruckfeder 40 in einem vorgespannten Zustand, wobei die mit ihrer Längsachse übereinstimmende Wirkrichtung der Gasdruckfeder 40 so gewählt ist, dass diese etwas unterhalb des Drehpunkts 28 verläuft. Dadurch werden der fünfte Hebelarm 38 und die mit diesem drehfest gekoppelten ersten und dritten Hebelarme 30, 34 entgegen dem Uhrzeigersinn beaufschlagt, so dass das Sitzteil 14 und das Rückenteil 18 in der in Fig. 1 dargestellten Grundposition gehalten werden.A fifth lever arm 38 is rotatably coupled to the first lever arm 30, at the same location as the third lever arm 34. A gas spring 40 is at one end to the base 12 below the seat portion 14 and at its other end to the free end hinged to the fifth lever arm 38. Fig. 1 shows the gas spring 40 in a prestressed state, wherein the matching with its longitudinal axis effective direction of the gas spring 40 is selected so that it extends slightly below the pivot point 28. As a result, the fifth lever arm 38 and the rotatably coupled thereto first and third lever arms 30, 34 counteracted in the counterclockwise direction, so that the seat part 14 and the back part 18 in the in Fig. 1 shown in the basic position.

Wenn nun z.B. das Sitzteil 14 aus dem Sitzmöbel 10 nach links herausgezogen wird, wird diese durch die Sitzteilführung 16 geführte Horizontalbewegung über den ersten und zweiten Hebelarm 30, 32 in eine Schwenkbewegung der Hebelanordnung 22 im Uhrzeigersinn umgesetzt, die wiederum über den dritten und vierten Hebelarm 34, 36 in eine Bewegung des Rückenteils 18 umgesetzt wird, so dass sich dieses in die durch die Rückenteilführung 20 vorgegebene Richtung nach oben bewegt.If now, e.g. the seat part 14 is pulled out of the seating 10 to the left, this is guided by the seat part guide 16 horizontal movement over the first and second lever arm 30, 32 in a pivoting movement of the lever assembly 22 in a clockwise direction, which in turn via the third and fourth lever arm 34, the 36th is converted into a movement of the back part 18, so that this moves in the direction predetermined by the back part guide 20 upwards.

Verstellt der Benutzer anstelle des Sitzteils 14 das Rückenteil 18, wird die Verschiebung des Rückenteils 18 auf analoge Weise durch die Hebelanordnung 22 in eine Verschiebebewegung des Sitzteils 14 umgewandelt.Adjust the user instead of the seat part 14, the back part 18, the displacement of the back portion 18 is converted in a similar manner by the lever assembly 22 in a sliding movement of the seat part 14.

Die durch eine Verschiebung des Sitzteils 14 oder des Rückenteils 18 bewirkte, im Uhrzeigersinn verlaufende Schwenkbewegung der Hebelanordnung 22 aus der in Fig. 1 dargestellten Grundposition in Richtung der Ausziehposition gemäß Fig. 2 hat zur Folge, dass sich aufgrund der Verschwenkung des fünften Hebelarms 38 die Wirkrichtung der Gasdruckfeder 40 in Richtung auf den Drehpunkt 28 verschiebt. Dabei wird die Gasdruckfeder 40 geringfügig weiter komprimiert. Wenn die Wirkrichtung der Gasdruckfeder den Drehpunkt 28 schneidet, befindet sich die Hebelanordnung 22 im Totpunkt.The caused by a displacement of the seat part 14 or the back part 18, clockwise pivoting movement of the lever assembly 22 from the in Fig. 1 shown basic position in the direction of the pull-out position according to Fig. 2 As a result, due to the pivoting of the fifth lever arm 38, the effective direction of the gas spring 40 in the direction of the pivot point 28 shifts. The gas spring 40 is compressed slightly further. When the effective direction of the gas spring intersects the pivot 28, the lever assembly 22 is at dead center.

Eine weitere Verschwenkung der Hebelanordnung 22 im Uhrzeigersinn führt zur Überwindung des Totpunkts. Die vorgespannte Gasdruckfeder 40 wirkt nun der Schwenkbewegung nicht mehr entgegen, sondern unterstützt diese, während sie sich gleichzeitig entspannt, da die Wirkrichtung der Gasdruckfeder 40 nunmehr oberhalb des Drehpunkts 28 verläuft.A further pivoting of the lever assembly 22 in a clockwise direction leads to overcoming the dead center. The prestressed gas spring 40 now no longer counteracts the pivoting movement, but supports it, while it relaxes at the same time, since the effective direction of the gas pressure spring 40 now extends above the pivot point 28.

Beim Ausziehen des Sitzteils 14 bzw. des Rückenteils 18 ist vom Benutzer also zunächst eine zusätzliche Kraft aufzubringen, die jedoch aufgrund der geschilderten Anordnung nach dem Kniehebelprinzip in der Nähe des Totpunkts sehr gering ist. Nach Überschreiten des Totpunkts unterstützt die Gasdruckfeder 40 die Verstellbewegung, bis die in Fig. 2 dargestellte, durch nicht gezeigte Endanschläge der Führungen 16, 20 begrenzte Ausziehposition erreicht ist. Durch die Kniehebelanordnung wird erreicht, dass Sitz- und Rückenteil 14, 18 in beiden Endpositionen durch die Kraft der Gasdruckfeder 40 gehalten sind.When the seat part 14 or the back part 18 is pulled out, the user therefore first has to apply an additional force which, however, is very low due to the described arrangement according to the toggle lever principle in the vicinity of the dead center. After exceeding the dead center, the gas spring 40 supports the adjustment movement until the in Fig. 2 shown, by not shown end stops of the guides 16, 20 limited extraction position is reached. The toggle lever arrangement ensures that the seat and back parts 14, 18 are held in both end positions by the force of the gas pressure spring 40.

Beim Einschieben des Sitzteils 14 bzw. des Rückenteils 18 wird die Gasdruckfeder 40 wieder gespannt, wobei zunächst eine Kraft vom Benutzer aufzubringen ist. Nach Überschreiten des Totpunkts unterstützt die Gasdruckfeder 40 den Einschiebevorgang und hält abschließend das Sitzteil 14 und das Rückenteil 18 wieder in der Grundposition fest.When inserting the seat part 14 and the back part 18, the gas spring 40 is stretched again, initially a force is applied by the user. After exceeding the dead center, the gas spring 40 assists the insertion process and finally holds the seat part 14 and the back part 18 fixed again in the basic position.

Während bei dem hier dargestellten Ausführungsbeispiel eines erfindungsgemäßen Sitzmöbels die Sitztiefe und die Lehnenhöhe gleichzeitig vergrößert bzw. vermindert werden, ist es bei entsprechender Anpassung der Hebelanordnung alternativ auch möglich, das Sitzteil und das Rückenteil so zu koppeln, dass eine Verminderung der Sitztiefe zugleich eine Vergrößerung der Lehnenhöhe bewirkt und umgekehrt.While in the illustrated embodiment of a seat according to the invention, the seat depth and the backrest height are increased or decreased simultaneously, it is with appropriate adjustment the lever arrangement alternatively also possible to couple the seat part and the back part so that a reduction in the seat depth at the same time causes an increase in the backrest height and vice versa.
