Description

Die vorliegende Erfindung betrifft ein Sitzmöbel gemäß dem Oberbegriff des Anspruchs 1 mit einem Sitzteil, einem Rückenteil, das aus einer zumindest im Wesentlichen aufrechten Sitzposition in eine geneigte Ruheposition verstellbar ist, und zumindest einem Armteil.The present invention relates to a chair according to the preamble of claim 1 with a seat part, a back part, which is adjustable from an at least substantially upright sitting position in an inclined rest position, and at least one arm part.

Derartige Sitzmöbel sind grundsätzlich bekannt, beispielsweise aus der DE 203 02 612 U1 . Bei dem Sitzmöbel kann es sich beispielsweise um einen Polstersessel, insbesondere Fernseh- oder Massagesessel, oder einen Bürostuhl handeln.Such seating are basically known, for example from the DE 203 02 612 U1 , The chair can be, for example, an upholstered chair, in particular a television or massage chair, or an office chair.

Es ist eine Aufgabe der Erfindung, ein gattungsgemäßes Sitzmöbel dahingehend weiterzuentwickeln, dass das Armteil im Rahmen seiner Bewegung zu einem möglichst optimalen Sitzkomfort beiträgt.It is an object of the invention to further develop a generic seating furniture in such a way that the arm part contributes to the best possible seating comfort as part of its movement.

Diese Aufgabe wird gelöst durch ein Sitzmöbel mit den Merkmalen des Anspruchs 1.This object is achieved by a chair with the features of claim 1.

Bei dem erfindungsgemäßen Sitzmöbel ist das Armteil mit dem Rückenteil über eine Kopplungsvorrichtung verbunden, so dass durch eine Verstellung des Rückenteils aus der Sitzposition in die Ruheposition eine Bewegung des Armteils relativ zum Sitzteil erfolgt. Erfindungsgemäß beschreibt die Bewegung einen Abschnitt einer Kreisbahn mit einem konstanten Radius. Das Armteil wird somit insbesondere gleichmäßig nach hinten gezogen. Vorzugsweise bleibt der Winkel zwischen dem Armteil und dem Rückenteil somit stets konstant. Alternativ ist beispielsweise auch ein Bewegungsablauf denkbar, welche flacher verläuft, also z.B. eine Bahn mit einem sich vergrößernden Radius.In the seating furniture according to the invention, the arm part is connected to the back part via a coupling device, so that a movement of the arm part takes place relative to the seat part by an adjustment of the back part from the sitting position to the rest position. According to the invention, the movement describes a section of a circular path with a constant radius. The arm part is thus particularly pulled back evenly. Preferably, the angle between the arm part and the back part thus always remains constant. Alternatively, for example Also, a movement conceivable, which runs flatter, ie, for example, a path with a widening radius.

In der Ruheposition, die auch Relaxposition genannt wird, ist das Rückenteil insbesondere gegenüber einer im Wesentlichen aufrechten bzw. leicht geneigten Sitzposition nach hinten geneigt. In der Sitzposition kann das Rückenteil beispielsweise einen Winkel zur Vertikalen von etwa 0° bis 40° und in der Ruheposition von etwa 40° bis 90°, vorzugsweise von etwa 50° bis 70°, einschließen.In the rest position, which is also called relaxation position, the back part is inclined in particular in relation to a substantially upright or slightly inclined seating position to the rear. For example, in the sitting position, the back portion may include an angle to the vertical of about 0 ° to 40 ° and in the rest position of about 40 ° to 90 °, preferably about 50 ° to 70 °.

Entsprechend kann sich das Armteil insbesondere auch in entgegengesetzte Richtung relativ zum Sitzteil bewegen, wenn das Rückenteil aus der Ruheposition in die Sitzposition verstellt wird.Accordingly, the arm part can in particular also move in the opposite direction relative to the seat part, when the back part is moved from the rest position to the sitting position.

Der Begriff "Armteil" ist vorliegend breit zu verstehen. So kann das Armteil eine Armlehne umfassen. Insbesondere kann jedoch auch ein gesamtes Seitenelement des Sitzmöbels mit einer Auflagefläche für die Arme als Armteil angesehen werden.The term "arm part" is to be understood broadly. Thus, the arm part may include an armrest. In particular, however, an entire side element of the seat with a support surface for the arms can be regarded as an arm part.

Mit Hilfe desselben Verstellmechanismus können somit vorzugsweise gleichzeitig sowohl das Rückenteil als auch das Armteil verstellt werden. Somit gestaltet sich das Verstellen des Sitzmöbels besonders einfach und komfortabel. Insbesondere bleibt der Abstand zwischen dem Rückenteil und dem Armteil beim Verstellen im Wesentlichen konstant.With the help of the same adjustment mechanism, both the back part and the arm part can thus be adjusted at the same time preferably simultaneously. Thus, the adjustment of the chair is particularly simple and comfortable. In particular, the distance between the back part and the arm part during adjustment remains substantially constant.

Das Armteil ist folglich sowohl in der Sitzposition als auch in der Ruheposition gut erreichbar, so dass stets eine bequeme Ablage der Arme möglich ist. Auch entsteht erfindungsgemäß keine ästhetisch nachteilige Lücke zwischen dem Armteil und dem Rückenteil.The arm part is therefore easily accessible both in the sitting position and in the rest position, so that always a comfortable storage of the arms is possible. Also arises according to the invention, no aesthetically unfavorable gap between the arm and the back part.

Da die Kopplungsvorrichtung einen Verbundarm und ein Gelenk umfasst, verbindet somit der Verbundarm das Armteil mit dem Rückenteil. Das Gelenk schafft dabei einen Freiheitsgrad für die Bewegung des Armteils.Thus, since the coupling device comprises a connecting arm and a hinge, the connecting arm connects the arm part to the back part. The joint creates a degree of freedom for the movement of the arm.

Da sich das Seitenteil zwischen dem Sitzteil und dem Armteil erstreckt, kann das Seitenteil optisch ansprechend geformt sein. Im Bereich des Armteils kann das Seitenteil insbesondere breiter sein als im Bereich des Sitzteils und z.B. der Breite des Armteils entsprechen.Since the side part extends between the seat part and the arm part, the side part can be formed visually appealing. In the region of the arm part, the side part may in particular be wider than in the region of the seat part and e.g. correspond to the width of the arm part.

Da das Seitenteil eine Führungsschiene für das Armteil umfasst oder mit einer Führungsschiene für das Armteil verbunden ist, kann das Armteil sich somit insbesondere relativ zum Seitenteil bewegen.Since the side part comprises a guide rail for the arm part or is connected to a guide rail for the arm part, the arm part can thus move in particular relative to the side part.

Weiterbildungen der Erfindung sind auch den abhängigen Ansprüchen, der Beschreibung sowie den beigefügten Zeichnungen zu entnehmen.Further developments of the invention can be found in the dependent claims, the description and the accompanying drawings.

Gemäß einer Ausführungsform umfasst die Bewegung eine Schiebebewegung, insbesondere nach hinten. Wird somit das Rückenteil nach hinten verstellt, verschiebt sich vorzugsweise auch das Armteil nach hinten, insbesondere in Richtung des Rückenteils.According to one embodiment, the movement comprises a sliding movement, in particular to the rear. Thus, if the back part is moved backwards, preferably also the arm part shifts to the rear, in particular in the direction of the back part.

Nach einer weiteren Ausführungsform ist der Verbundarm starr ausgebildet ist. Bei einer starren Ausbildung des Verbundarms ist ein Gelenk vorteilhaft. Alternativ kann auch ein flexibler Verbundarm vorgesehen sein, beispielsweise aus einem Gummimaterial. Ferner ist es möglich, den Verbundarm als eine mehrgliedrige Einheit auszubilden.According to a further embodiment, the connecting arm is rigid. In a rigid design of the composite arm, a joint is advantageous. Alternatively, a flexible composite arm may be provided, for example of a rubber material. Further, it is possible to form the composite arm as a multi-unit unit.

Gemäß einer weiteren Ausführungsform weist der Verbundarm eine Biegung auf. Insbesondere kann ein dem Rückenteil zugeordneter Abschnitt des Verbundarms nach oben gebogen sein. Vorzugsweise kann ein dem Armteil zugeordneter Abschnitt an die Form des Armteils angepasst sein.According to a further embodiment, the connecting arm has a bend. In particular, a portion of the connecting arm assigned to the back part can be bent upwards. Preferably, a portion associated with the arm part can be adapted to the shape of the arm part.

Nach einer weiteren Ausführungsform ist der Verbundarm als längliche Platte ausgebildet. Die Länge kann dabei z.B. zwischen 20 cm und 70 cm betragen. Die, insbesondere gebogene, Platte kann sich somit vom Armteil bis zum Rückenteil erstrecken. Vorzugsweise ist die Platte vergleichsweise dünn, z.B. zwischen 0,5 cm und 2 cm. Insbesondere ist die Platte unter einer Polsterung nicht sichtbar.According to a further embodiment, the composite arm is formed as an elongate plate. The length can be e.g. between 20 cm and 70 cm. The, in particular curved, plate can thus extend from the arm to the back part. Preferably, the plate is comparatively thin, e.g. between 0.5 cm and 2 cm. In particular, the plate is not visible under a padding.

Gemäß einer weiteren Ausführungsform entspricht die Breite der Platte zumindest im Wesentlichen der Breite des Armteils. Die Platte ist somit an die Ausgestaltung des Armteils angepasst.According to a further embodiment, the width of the plate corresponds at least substantially to the width of the arm part. The plate is thus adapted to the configuration of the arm part.

Nach einer weiteren Ausführungsform ist der Verbundarm aus Metall ausgebildet. Der Verbundarm ist daher stabil genug, um das Armteil bei einer Verstellung des Rückenteils mitzubewegen.According to a further embodiment, the composite arm is formed of metal. The composite arm is therefore stable enough to move the arm part in an adjustment of the back part.

Gemäß einer weiteren Ausführungsform ist der Verbundarm starr mit dem Armteil verbunden. Eine Relativbewegung zwischen dem Armteil und dem Verbundarm ist folglich nicht vorgesehen. Vorzugsweise kann der Verbundarm, insbesondere eine gebogene Platte, mit dem Armteil zumindest teilweise überlappen, um so einen Befestigungsbereich zur Befestigung des Verbundarms am Armteil zu schaffen. Alternativ kann der Verbundarm auch einstückig mit dem Armteil ausgebildet sein.According to a further embodiment, the connecting arm is rigidly connected to the arm part. A relative movement between the arm part and the connecting arm is therefore not provided. Preferably, the composite arm, in particular a curved plate, at least partially overlap with the arm portion so as to provide a mounting area for attachment of the composite arm to the arm portion. Alternatively, the connecting arm may also be formed integrally with the arm part.

Nach einer weiteren Ausführungsform ist der Verbundarm mit dem Armteil verschraubt. Dies ermöglicht eine kostengünstige Befestigung. Es sind grundsätzlich jedoch beliebige Befestigungsmittel denkbar, beispielsweise Klebe- und/oder Schweißmittel.According to a further embodiment, the connecting arm is screwed to the arm part. This allows a cost-effective attachment. However, in principle, any attachment means are conceivable, for example adhesives and / or welding agents.

Gemäß einer weiteren Ausführungsform ist genau ein Gelenk vorgesehen. Zwischen dem Armteil und dem Rückenteil besteht somit ein singulärer Drehpunkt. Weitere Relativbewegungen sind dabei nicht vorgesehen.According to another embodiment, exactly one joint is provided. There is thus a singular point of rotation between the arm part and the back part. Other relative movements are not provided.

Gemäß der Erfindung ist das Gelenk mit dem Rückenteil verbunden. Gemäß einer weiteren Ausführungsform ist das Gelenk als Scharnier ausgebildet. Das Gelenk ist somit kostengünstig herstellbar.According to the invention, the joint is connected to the back part. According to a further embodiment, the joint is designed as a hinge. The joint is thus inexpensive to produce.

Gemäß einer weiteren Ausführungsform ist das Seitenteil starr mit dem Sitzteil verbunden. Eine Relativbewegung zwischen dem Seitenteil und dem Sitzteil ist somit nicht vorgesehen. Es sind beliebige Befestigungsmittel möglich, die beispielsweise Schraub-, Klebe- und/oder Schweißverbindungen aufweisen können.According to a further embodiment, the side part is rigidly connected to the seat part. A relative movement between the side part and the seat part is thus not provided. There are any attachment means possible, which may have, for example, screw, adhesive and / or welded joints.

Gemäß einer weiteren Ausführungsform umfasst die Führungsschiene eine Rundstange. Diese ist insbesondere kostengünstig herstellbar. Alternativ kann die Führungsschiene auch eine Stange mit Kanten, z.B. eine Vierkant-Stange, aufweisen. Nach einer Weiterbildung umfasst das Armteil eine Hülse, die die Rundstange umgreift. Das Armteil kann somit sicher geführt werden.According to a further embodiment, the guide rail comprises a round rod. This is particularly inexpensive to produce. Alternatively, the guide rail can also be a bar with edges, e.g. a square bar. According to a development, the arm part comprises a sleeve which engages around the round rod. The arm part can thus be guided safely.

Grundsätzlich sind jedoch beliebige Führungen möglich. So kann die Führungsschiene alternativ insbesondere im Wesentlichen horizontal orientiert sein und eine sich längs erstreckende, zentrale Nut umfassen, so dass ein wie auch immer ausgebildetes Führungselement, beispielsweise ein Rollkörper oder ein Nutenstein, des Armteils von oben in die Nut eingreifen kann. Das Armteil kann somit insbesondere in einer Kulissenführung geführt werden.In principle, however, any guides are possible. Thus, the guide rail may alternatively be orientated in particular substantially horizontally and comprise a longitudinally extending, central groove, so that any guide element, for example a rolling element or a sliding block, of the arm part can engage in the groove from above. The arm part can thus be guided in particular in a sliding guide.

Gemäß einer weiteren Ausführungsform ist zum, insbesondere stufenlosen, Verstellen des Rückenteils eine erste Feder vorgesehen ist. Die Feder kann zentral oder auf einer Seite des Rückenteils angeordnet sein. Auch sind z.B. zwei Federn möglich, die jeweils an unterschiedlichen Seiten des Rückenteils angeordnet sein können.According to a further embodiment, a first spring is provided for, in particular stepless, adjustment of the back part. The spring can be arranged centrally or on one side of the back part. Also, e.g. two springs possible, which can be arranged in each case on different sides of the back part.

Nach einer Weiterbildung kann es sich bei der Feder um eine Spiralfeder, eine Gasdruckfeder oder eine Gaszugfeder handeln. Dies ermöglicht auf einfache Weise eine kraftschonende Verstellung des Rückenteils.According to a development, the spring may be a spiral spring, a gas spring or a gas spring. This allows a simple way a power-saving adjustment of the back part.

Das Verstellen des Rückenteils aus der Sitzposition in die Ruheposition kann durch Muskelkraft beim Zurücklehnen durch einen Benutzer erfolgen. Um das Rückenteil wieder zurück in die Sitzposition zu bewegen, wird das Rückenteil durch die Feder nach vorne gezogen. Je nach Anordnung der Feder kann eine Zug- oder eine Druckfeder vorgesehen sein.The adjustment of the back part from the sitting position to the rest position can be done by muscle power when leaning back by a user. To move the back part back into the sitting position, the back part is pulled forward by the spring. Depending on the arrangement of the spring, a tension or a compression spring may be provided.

Gemäß einer weiteren Ausführungsform ist zum Verstellen des Rückenteils eine erste Auslösevorrichtung vorgesehen, welche mit der ersten Feder, insbesondere der ersten Gaszugfeder, über eine erste Wirkeinrichtung in Verbindung steht. Bei der Auslösevorrichtung kann es sich z.B. um einen Hebel und/oder Schalter handeln. Durch die Auslösevorrichtung kann das Rückenteil insbesondere entriegelt und in einer gewünschten Neigung, insbesondere stufenlos, festgestellt werden. Das Rückenteil kann somit auch in beliebigen Zwischenpositionen zwischen der Sitz- und der Ruheposition fixiert werden.According to a further embodiment, a first triggering device is provided for adjusting the back part, which is in communication with the first spring, in particular the first throttle cable spring, via a first active device. The triggering device may be e.g. to act a lever and / or switch. By the triggering device, the back part can be unlocked in particular and in a desired inclination, in particular continuously, be determined. The back part can thus be fixed in any intermediate positions between the sitting and the rest position.

Nach einer weiteren Ausführungsform umfasst die erste Wirkeinrichtung einen ersten Bowdenzug. Somit lässt sich die Auslösevorrichtung auf einfache Weise mit der Feder verbinden.According to a further embodiment, the first active device comprises a first Bowden cable. Thus, the triggering device can be easily connected to the spring.

Gemäß einer weiteren Ausführungsform ist die erste Auslösevorrichtung in einem Seitenteil angeordnet. Die Auslösevorrichtung ist für den Benutzer folglich bequem zu erreichen.According to a further embodiment, the first triggering device is arranged in a side part. The triggering device is therefore convenient for the user to reach.

Nach einer weiteren Ausführungsform ist für eine, insbesondere stufenlose, Höhenverstellung des Sitzteils relativ zu einer, vorzugsweise unbeweglichen, Basis eine zweite Gasdruckfeder vorgesehen. Bei der Basis, die insbesondere das Sitzteil abstützt, kann es sich z.B. um eine zentrale Säule oder einen Drehfuß oder um zwei beabstandete Seitenwände handeln, an denen sich das Sitzteil abstützt. Die Gasdruckfeder kann zentral oberhalb eines Drehfußes und unterhalb des Sitzteils angeordnet sein. Die zweite Gasdruckfeder ermöglicht auf einfache Weise eine kraftschonende Höhenverstellung des Sitzteils. Die Höhenverstellung kann insbesondere zwischen 30 mm und 80 mm, vorzugsweise etwa 60 mm, betragen.According to a further embodiment, a second gas spring is provided for a, in particular stepless, height adjustment of the seat part relative to a, preferably immovable, base. In the base which particularly supports the seat part, it may e.g. act around a central pillar or a swivel foot or two spaced side walls on which the seat part is supported. The gas spring can be arranged centrally above a swivel base and below the seat part. The second gas spring allows a simple way a power-saving height adjustment of the seat part. The height adjustment may be in particular between 30 mm and 80 mm, preferably about 60 mm.

Gemäß einer weiteren Ausführungsform ist die zweite Gasdruckfeder als Druckfeder ausgebildet. Das Verstellen des Sitzteils in eine tiefere Position kann durch das Gewicht eines Benutzers erfolgen. Um das Sitzteil wieder nach oben zu bewegen, wird das Sitzteil durch die Gasdruckfeder nach oben gedrückt.According to a further embodiment, the second gas spring is formed as a compression spring. The adjustment of the seat part in a lower position can be done by the weight of a user. In order to move the seat part up again, the seat part is pushed upwards by the gas pressure spring.

Nach einer weiteren Ausführungsform ist zur Höhenverstellung des Sitzteils eine zweite Auslösevorrichtung vorgesehen, welche mit der zweiten Gasdruckfeder über eine zweite Wirkeinrichtung in Verbindung steht. Bei der Auslösevorrichtung kann es sich z.B. um einen Hebel und/oder Schalter handeln. Durch die Auslösevorrichtung kann das Sitzteil insbesondere entriegelt und in einer gewünschten Höhe, insbesondere stufenlos, festgestellt werden. Das Sitzteil kann somit in beliebigen Zwischenpositionen zwischen ganz unten und ganz oben fixiert werden.According to a further embodiment, a second triggering device is provided for height adjustment of the seat part, which is in communication with the second gas spring via a second active device. The triggering device may be e.g. to act a lever and / or switch. By the triggering device, the seat part can be unlocked in particular and at a desired height, in particular continuously, be determined. The seat part can thus be fixed in any intermediate positions between the very bottom and the top.

Gemäß einer weiteren Ausführungsform umfasst die zweite Wirkeinrichtung einen zweiten Bowdenzug. Somit lässt sich die Auslösevorrichtung auf einfache Weise mit der Gasdruckfeder verbinden.According to a further embodiment, the second active device comprises a second Bowden cable. Thus, the triggering device can be easily connected to the gas spring.

Nach einer weiteren Ausführungsform ist die zweite Auslösevorrichtung in einem Seitenteil angeordnet. Die Auslösevorrichtung ist für den Benutzer daher bequem zu erreichen.According to a further embodiment, the second triggering device is arranged in a side part. The triggering device is therefore easily accessible to the user.

Gemäß einer weiteren Ausführungsform sind die erste und die zweite Auslösevorrichtung in jeweils unterschiedlichen Seitenteilen angeordnet. So kann der Benutzer auf einer Seite die Höhe des Sitzteils regulieren und auf einer anderen Seite die Neigung des Rückenteils einstellen. Alternativ ist es jedoch auch möglich, beide Auslösevorrichtungen auf derselben Seite anzuordnen.According to a further embodiment, the first and the second triggering device are arranged in respectively different side parts. Thus, the user can regulate the height of the seat part on one side and adjust the inclination of the back part on another side. Alternatively, however, it is also possible to arrange both release devices on the same side.

Nach einer weiteren Ausführungsform ist eine Fußstütze vorgesehen, welche aus einer eingefahrenen Warteposition in eine ausgefahrene Stützposition verstellbar ist. Die Fußstütze erhöht insbesondere in der Ruheposition den Komfort.According to a further embodiment, a footrest is provided, which is adjustable from a retracted waiting position to an extended support position. The footrest increases comfort, especially in the rest position.

Gemäß einer weiteren Ausführungsform ist zum Verstellen der Fußstütze eine dritte Auslösevorrichtung vorgesehen. Die Auslösevorrichtung kann insbesondere als Hebel oder Schalter ausgebildet sein.According to a further embodiment, a third triggering device is provided for adjusting the footrest. The triggering device can be designed in particular as a lever or switch.

Nach einer weiteren Ausführungsform ist die dritte Auslösevorrichtung am Sitzteil angeordnet. Grundsätzlich kann die Auslösevorrichtung jedoch beliebig am Sitzmöbel befestigt sein, beispielsweise in einem Seitenteil.According to a further embodiment, the third triggering device is arranged on the seat part. In principle, however, the triggering device can be attached as desired to the seating, for example in a side part.

Gemäß einer weiteren Ausführungsform sind die erste, zweite und/oder dritte Auslösevorrichtung unabhängig voneinander auslösbar. So kann das Rückenteil unabhängig von der Höhenverstellung des Sitzteils eingestellt werden. Auch kann die Fußstütze unabhängig von der Höhenverstellung des Sitzteils bzw. der Neigungsverstellung des Rückenteils ein- bzw. ausgeklappt werden.According to a further embodiment, the first, second and / or third triggering device can be triggered independently of one another. Thus, the back part can be adjusted independently of the height adjustment of the seat part. The footrest can also be folded in or out independently of the height adjustment of the seat part or of the inclination adjustment of the back part.

Die Erfindung wird im Folgenden beispielhaft unter Bezugnahme auf die Zeichnung beschrieben. Es zeigt:

Figur
eine schematische Seitenansicht einer Ausführungsform eines erfindungsgemäßen Sitzmöbels.
The invention will now be described by way of example with reference to the drawings. It shows:
figure
a schematic side view of an embodiment of a seat according to the invention.

In der Figur ist schematisch ein Polstersessel mit einem als Rückenlehne 10 ausgebildeten Rückenteil gezeigt, welches in Verstellrichtung V zwischen einer aufrechten Sitzposition und einer geneigten Ruhe- oder Relaxposition verstellt werden kann. Beide Positionen sind überlagert in der Figur dargestellt.In the figure, a upholstered chair is shown schematically with a formed as a backrest 10 back part, which can be adjusted in the adjustment direction V between an upright sitting position and an inclined rest or relaxation position. Both positions are superimposed in the figure.

Ferner umfasst der Sessel als Armlehnen 12 ausgebildete Armteile, die jeweils über eine als Kopplungsvorrichtung 14 dienende, gebogene Platte mit der Rückenlehne 10 verbunden sind.Furthermore, the armchair comprises as armrests 12 formed arm parts, which are each connected via a serving as a coupling device 14, curved plate with the backrest 10.

Jede Armlehne 12 ist relativ zu einem Seitenteil 16 in Bewegungsrichtung B beweglich. Das Seitenteil 16 ist wiederum fest mit einem Sitzteil 18 verbunden und beispielsweise damit verschraubt.Each arm 12 is movable relative to a side member 16 in the direction of movement B. The side part 16 is in turn fixedly connected to a seat part 18 and screwed for example.

Das Sitzteil 18 ist an einer als Drehfuß 20 ausgebildeten Basis angeordnet. Am Sitzteil 18 ist eine Fußstütze 22 befestigt, welche aus einer eingefahrenen Warteposition in eine ausgefahrene Stützposition verstellt werden kann.The seat part 18 is arranged on a base formed as a swivel base 20. On the seat part 18, a footrest 22 is attached, which can be adjusted from a retracted waiting position to an extended support position.

Zum Verstellen der Rückenlehne 10 ist eine erste, als Gaszugfeder 24 ausgebildete Feder vorgesehen, welche die Rückenlehne 10 auf Zug belastet. Somit kann die Rückenlehne 10 aus der Ruheposition stufenlos in eine Sitzposition verstellt werden. Zum Auslösen dieser ersten Gaszugfeder 24 ist eine erste Auslösevorrichtung 26 im Seitenteil 16 vorgesehen, welche mit der ersten Gaszugfeder 24 über einen nicht gezeigten Bowdenzug verbunden ist. Um die Rückenlehne 10 aus der Sitzposition in die Ruheposition zu verstellen, lehnt sich ein Benutzer zurück und drückt so die Rückenlehne 10 nach hinten. Befindet sich die Rückenlehne 10 in der gewünschten Position, kann die Rückenlehne 10 mit Hilfe der Auslösevorrichtung 26 festgestellt werden.To adjust the backrest 10, a first spring configured as a gas tension spring 24 is provided which loads the backrest 10 in tension. Thus, the backrest 10 can be adjusted from the rest position continuously in a sitting position. To trigger this first accelerator cable 24, a first triggering device 26 is provided in the side part 16, which is connected to the first accelerator cable 24 via a Bowden cable, not shown. To adjust the backrest 10 from the sitting position to the rest position, a user leans back and pushes the backrest 10 to the rear. If the backrest 10 is in the desired position, the backrest 10 can be detected with the aid of the triggering device 26.

Beim Verstellen der Rückenlehne 10 werden auch die Armlehnen 12 verstellt. Hierzu weist die Kopplungsvorrichtung 14 einen als Platte 28 ausgebildeten Verbundarm sowie ein Gelenk 30 auf, welches an der Rückenlehne 10 angeordnet ist.When adjusting the backrest 10 and the armrests 12 are adjusted. For this purpose, the coupling device 14 has a connecting arm formed as a plate 28 and a hinge 30, which is arranged on the backrest 10.

Insbesondere kann das Gelenk 30 durch ein zu einer Gelenkhülse gebogenes Endstück der Platte 28 und einen Bolzen gebildet werden. Der Bolzen kann mit der Rückenlehne 10 starr verbunden, insbesondere verschweißt, sein, während die Gelenkhülse den Bolzen umgreifen kann.In particular, the hinge 30 can be formed by a bent to a joint sleeve end of the plate 28 and a bolt. The bolt can be rigidly connected to the backrest 10, in particular welded, while the joint sleeve can embrace the bolt.

Die Platte 28 ist mit der Armlehne 12 fest verschraubt. Die Armlehne 12 umfasst eine Hülse 32, welche eine als Rundstange 34 ausgebildete Führungsschiene des Seitenteils 16 umgreift und somit relativ zum Seitenteil 16 verschieblich gelagert ist. Die Rundstange 34 ist auch in der oben dargestellten Draufsicht auf die aus Sicht eines Benutzers rechte Armlehne 12 dargestellt. Links ist eine Vorderansicht der rechten Armlehne 12 samt Seitenteil 16 gezeigt.The plate 28 is bolted to the armrest 12. The armrest 12 comprises a sleeve 32 which engages around a guide rail of the side part 16 formed as a round rod 34 and is thus displaceably mounted relative to the side part 16. The round bar 34 is also shown in the above-described plan view of the right-hand armrest 12 as seen by a user. On the left is a front view of the right armrest 12 together with side part 16 is shown.

Das Sitzteil 18 samt Seitenteil 16, Armlehnen 12 und Rückenlehne 10 kann auch in Höhenverstellrichtung H in der Höhe verstellt werden. Hierbei ist eine zweite, als Gasdruckfeder 36 ausgebildete Feder vorgesehen, welche über eine zweite Auslösevorrichtung 38 aktiviert werden kann. Die zweite Auslösevorrichtung 38 kann über einen Bowdenzug mit der Gasdruckfeder 36 verbunden und in einem Seitenteil 16 angeordnet sein. Zur vereinfachten Darstellung sind in der Figur sowohl die erste als auch die zweite Auslösevorrichtung 26, 38 im selben Seitenteil 16 gezeigt. Vorzugsweise sind diese jedoch jeweils an einem anderen Seitenteil 16 angeordnet.The seat part 18 together with the side part 16, armrests 12 and backrest 10 can also be adjusted in height adjustment H in height. Here, a second, designed as a gas spring 36 spring is provided, which can be activated via a second triggering device 38. The second triggering device 38 may be connected via a Bowden cable to the gas spring 36 and arranged in a side part 16. For the sake of simplicity, both the first and the second triggering devices 26, 38 in the same side part 16 are shown in the figure. Preferably, however, these are each arranged on a different side part 16.

Zum Ausfahren der Fußstütze 22 ist eine als Hebel 40 ausgebildete dritte Auslösevorrichtung vorgesehen.To extend the footrest 22 designed as a lever 40 third triggering device is provided.

Erfindungsgemäß kann die Fußstütze 22 unabhängig von der Höhenverstellung des Sitzteils 16 verstellt werden. Auch die Verstellung der Rückenlehne 10 erfolgt unabhängig von einer Höhenverstellung bzw. einer Verstellung der Fußstütze 22.According to the invention, the footrest 22 can be adjusted independently of the height adjustment of the seat part 16. The adjustment of the backrest 10 is independent of a height adjustment or an adjustment of the footrest 22nd

Die Neigung der Rückenlehne 10 sowie die Höhe des Sitzteils 18 können aufgrund der Gaszug- bzw. Gasdruckfedern 24, 36 stufenlos eingestellt werden. Somit ist auf einfache Weise eine individuelle Anpassung an die Anforderungen des Benutzers möglich.The inclination of the backrest 10 and the height of the seat part 18 can be adjusted continuously due to the throttle cable or gas pressure springs 24, 36. Thus, an individual adaptation to the requirements of the user is possible in a simple manner.
