Ein gattungsgemäßer Stuhl mit einer (im Rahmen einer vorgesehenen Nutzung) verformbaren Sitzschale, die einen Sitzteil und eine Rückenlehne (vorzugsweise einstückig) ausbildet, und einem Gestell, wobei der Sitzteil über ein erstes Drehgelenk und die Rückenlehne über ein zweites Drehgelenk mit dem Gestell verbunden sind, wobei die Drehgelenke ein durch ein Verformen der Sitzschale bedingtes Verdrehen des Sitzteils und der Rückenlehne relativ zu dem Gestell ermöglichen und wobei das zweite Drehgelenk mittig bezüglich der Querrichtung des Stuhls mit der Rückenlehne verbunden ist, ist erfindungsgemäß dadurch gekennzeichnet, dass das erste Drehgelenk ein Verdrehen um zumindest eine (gegebenenfalls ausschließlich diese eine) in Hochrichtung des Stuhls ausgerichtete erste Drehachse ermöglicht und/oder das zweite Drehgelenk ein Verdrehen um zumindest eine (gegebenenfalls ausschließlich diese eine) in Längsrichtung des Stuhls ausgerichtete zweite Drehachse ermöglicht.A generic chair with a (in the context of a proposed use) deformable seat shell, which forms a seat part and a backrest (preferably in one piece), and a frame, wherein the seat part via a first pivot and the backrest are connected via a second pivot to the frame wherein the hinges enable a twisting of the seat part and the backrest relative to the frame caused by a deformation of the seat shell, and wherein the second pivot joint is connected to the backrest centrally with respect to the transverse direction of the chair, according to the invention, characterized in that the first pivot joint is twisting around at least one (possibly only this one) in the vertical direction of the chair aligned first axis of rotation allows and / or the second pivot allows rotation about at least one (possibly only this one) aligned in the longitudinal direction of the chair second axis of rotation.
Dabei wird unter der "Querrichtung" des Stuhls jede Richtung verstanden, die sich von einer Seite des Stuhls (insbesondere einer Projektion des Stuhls in eine neben dieser Seite des Stuhls angeordnete, vertikal ausgerichtete Ebene) in Richtung der anderen Seite des Stuhls (insbesondere einer Projektion des Stuhls in eine neben dieser anderen Seiten des Stuhls angeordnete, vertikal ausgerichtete Ebene) erstreckt.In this case, the "transverse direction" of the chair means any direction extending from one side of the chair (in particular a projection of the chair into a vertically aligned plane adjacent to this side of the chair) towards the other side of the chair (in particular a projection of the chair into a vertically aligned plane adjacent to this other side of the chair).
Dementsprechend wird unter der "Hochrichtung" des Stuhls jede Richtung verstanden, die sich von einer Unterseite des Stuhls (insbesondere einer Projektion des Stuhls in eine unterhalb des Stuhls angeordnete, horizontal ausgerichtete Ebene) in Richtung einer Oberseite des Stuhls (insbesondere einer Projektion des Stuhls in eine oberhalb des Stuhls horizontal ausgerichtete Ebene) erstreckt.Accordingly, the "vertical direction" of the chair means any direction extending from an underside of the chair (in particular a projection of the chair into a horizontally oriented plane located below the chair) towards an upper side of the chair (in particular a projection of the chair in FIG a plane horizontally oriented above the chair).
Dementsprechend wird unter Längsrichtung des Stuhls jede Richtung verstanden, die sich von einer Rückseite des Stuhls (insbesondere einer Projektion des Stuhls in eine hinter dem Stuhl angeordnete, vertikal ausgerichtete Ebene) in Richtung einer Vorderseite des Stuhls (insbesondere einer Projektion des Stuhls in eine auf der Vorderseite des Stuhls vertikal ausgerichtete Ebene) erstreckt.Accordingly, the longitudinal direction of the chair is understood to mean any direction that extends from a rear side of the chair (in particular a projection of the chair into a vertically aligned plane behind the chair) in the direction of a front side of the chair (in particular a projection of the chair into a position on the chair) Front of the chair vertically aligned plane) extends.
Die erfindungsgemäße Ausgestaltung des Stuhls sieht somit eine Anordnung der zwei die Sitzschale mit dem Gestell verbindenden Drehgelenke in der Sagittalebene eines Nutzers des Stuhls vor. Dies ermöglicht die Verwirklichung der gewünschten Beweglichkeit in Verbindung mit der verformbaren Sitzschale, wobei die Anzahl der für die Ausbildung des Gestells benötigten Teile im Vergleich zu dem aus der
Durch eine Verdrehbarkeit des ersten Drehgelenks um zumindest eine in Hochrichtung des Stuhls ausgerichtete erste Drehachse und/oder durch eine Verdrehbarkeit des zweiten Drehgelenks um zumindest eine in Längsrichtung des Stuhls ausgerichtete zweite Drehachse wird eine möglichst weitgehende Verformung der Sitzschale zugelassen.By a rotatability of the first pivot around at least one aligned in the vertical direction of the chair first axis of rotation and / or rotatability of the second pivot around at least one aligned in the longitudinal direction of the chair second axis of rotation as far as possible deformation of the seat is allowed.
In einer bevorzugten Ausgestaltung des erfindungsgemäßen Stuhls kann vorgesehen sein, dass der Sitzteil noch über mindestens ein Lager mit dem Gestell verbunden ist, wobei das Lager derart ausgebildet ist, dass dieses ein Verdrehen des Sitzteils um eine in Längsrichtung des Stuhls ausgerichtete Achse behindert. Dadurch wird der Sitzschale im Bereich des Sitzteils eine Stabilität gegeben, die ein seitliches Verkippen der Sitzschale im Bereich der Sitzvorderkante bei einer außermittigen Belastung durch den Nutzer behindert. Bei entsprechender Positionierung des Lagers, insbesondere in der Nähe der Sitzvorderkante, behindert dieses dabei auch nicht die vorgesehene Verformbarkeit der Sitzschale im Rahmen der Nutzung des Stuhls.In a preferred embodiment of the chair according to the invention can be provided that the seat part is still connected via at least one bearing with the frame, wherein the bearing is designed such that this obstructs a rotation of the seat part about an aligned in the longitudinal direction of the chair axis.

With appropriate positioning of the bearing, especially in the vicinity of the seat leading edge, this does not hinder the intended deformability of the seat in the context of the use of the chair.
Das Lager kann funktional in das erste Drehgelenk integriert sein. Vorteilhaft kann jedoch sein, wenn das Lager separat von dem ersten Drehgelenk ausgebildet ist und insbesondere von diesem in Querrichtung des Stuhls beabstandet angeordnet ist. Besonders bevorzugt können mindestens zwei solcher Lager vorgesehen sein, die beidseitig beabstandet des ersten Drehlagers angeordnet sind.The bearing can be functionally integrated into the first pivot. However, it can be advantageous if the bearing is formed separately from the first rotary joint and in particular is arranged at a distance therefrom in the transverse direction of the chair. Particularly preferably, at least two such bearings can be provided, which are arranged spaced on both sides of the first pivot bearing.
Eine konstruktiv einfache und funktional vorteilhafte Ausgestaltung des oder der Lager kann vorsehen, dass zwei Lagerteile, von denen eines mit dem Gestell und das andere mit der Sitzschale verbunden ist, zueinander in einer sich in Querrichtung und Längsrichtung des Stuhls erstreckenden Ebene verschiebbar sind.A structurally simple and functionally advantageous embodiment of the bearing or bearings can provide that two bearing parts, one of which is connected to the frame and the other with the seat shell, are mutually displaceable in a plane extending in the transverse direction and longitudinal direction of the chair.
Um eine möglichst weitgehende Verformung der Sitzschale zuzulassen, kann bei dem erfindungsgemäßen Stuhl weiterhin vorgesehen sein, dass das erste Drehgelenk in der die Sitzvorderkante umfassenden Hälfte, vorzugsweise in dem die Sitzvorderkante umfassenden Drittel oder Viertel und besonders bevorzugt in dem die Sitzvorderkante umfassenden Fünftel (jeweils bezogen auf die Erstreckung des Sitzteils in Längsrichtung des Stuhls) des Sitzteils angeordnet ist.In order to allow as far as possible deformation of the seat, it may further be provided in the chair according to the invention that the first hinge in the comprehensive half of the seat edge, preferably in the third or quarter of the seat leading edge and particularly preferably in the fifth seat covering the seat leading edge (each related on the extension of the seat part in the longitudinal direction of the chair) of the seat part is arranged.
Dem gleichen Zweck kann dienen, wenn das zweite Drehgelenk oberhalb des Körperschwerpunkts eines (Norm-)Nutzers angeordnet ist. Dabei kann das zweite Drehgelenk insbesondere in der die obere Rückenlehnenkante aufweisenden Hälfte (bezogen auf die Erstreckung der Rückenlehne in Hochrichtung des Stuhls) der Rückenlehne angeordnet sein.The same purpose may be served if the second pivot is located above the body center of gravity of a (norm) user. In this case, the second pivot, in particular in the upper backrest edge having half (Regarding the extent of the backrest in the vertical direction of the chair) of the backrest to be arranged.
Dabei wird unter "(Norm-)Nutzer" beispielsweise das P95-Perzentil der erwachsenen Personen verstanden.For example, "(standard) user" means the adult P95 percentile.
In einer weiterhin bevorzugten Ausgestaltung des erfindungsgemäßen Stuhls kann vorgesehen sein, dass ein über das zweite Drehgelenk mit der Rückenlehne verbundener Rückenlehnenträger des Gestells über ein drittes Drehgelenk mit einer über das erste Drehgelenk mit dem Sitzteil verbundenen Sitzbasis des Gestells verbunden ist. Dabei definiert das dritte Drehgelenk eine in Querrichtung des Stuhls ausgerichtete Drehachse. Insbesondere kann vorgesehen sein, dass das dritte Drehgelenk in Längsrichtung des Stuhls von dem ersten Drehgelenk beabstandet ist, sich somit die von dem ersten Drehgelenk definierte, mindestens eine Drehachse und die von dem dritten Drehgelenk definierte, mindestens eine Drehachse nicht schneiden. Durch eine solche Ausgestaltung des erfindungsgemäßen Stuhls wird eine Neigungsbeweglichkeit für den Stuhl geschaffen, die von Nutzern regelmäßig als komfortabel empfunden wird.In a further preferred embodiment of the chair according to the invention can be provided that a connected via the second pivot with the backrest backrest support of the frame is connected via a third pivot with a connected via the first pivot to the seat part seat base of the frame. In this case, the third pivot defines an aligned in the transverse direction of the chair axis of rotation. In particular, it can be provided that the third rotary joint is spaced apart from the first rotary joint in the longitudinal direction of the chair, thus the at least one axis of rotation defined by the first rotary joint and the at least one axis of rotation defined by the third rotary joint do not intersect. By such an embodiment of the chair according to the invention a tilt mobility for the chair is created, which is regularly perceived by users as comfortable.
Als besonders komfortabel wird eine solche Neigungsbeweglichkeit empfunden, wenn ein Zurücklehnen mit einer zumindest geringfügigen Körperstreckung verbunden ist. Demnach kann bei dem erfindungsgemäßen Stuhl vorzugsweise vorgesehen sein, dass dieser zwischen wenigstens einer aufrechten ersten Stellung und einer zurückgeneigten zweiten Stellung verstellbar ist, wobei ein Winkel zwischen Sitzteil und Rückenlehne in der zweiten Stellung größer als in der ersten Stellung ist.Such a tilt mobility is perceived as particularly comfortable when reclining is associated with at least slight extension of the body. Accordingly, in the chair according to the invention may preferably be provided that this is adjustable between at least an upright first position and a reclined second position, wherein an angle between the seat part and the backrest in the second position is greater than in the first position.
Eine solche Winkelveränderung zwischen dem Sitzteil und der Rückenlehne kann auf konstruktiv einfache Weise realisiert werden, indem der Rückenlehnenträger L-förmig oder bogenförmig ausgebildet ist, wobei ein erster Schenkel des L-förmigen Rückenlehnenträgers oder eine erste Hälfte des bogenförmigen Rückenlehnenträgers über das dritte Drehgelenk mit der Sitzbasis und ein zweiter Schenkel des L-förmigen Rückenlehnenträgers oder eine zweite Hälfte des bogenförmigen Rückenlehnenträgers über das zweite Drehgelenk mit der Rückenlehne verbunden ist.Such a change in angle between the seat part and the backrest can be realized in a structurally simple manner by the backrest support L-shaped or arcuate, wherein a first leg of the L-shaped backrest support or a first half of the arcuate backrest support via the third hinge with the Seat base and a second leg of the L-shaped backrest support or a second half of the arcuate Backrest support is connected via the second pivot with the backrest.
Um insbesondere bei der Realisierung einer Neigungsbeweglichkeit des Stuhls eine unvorteilhafte Verformung der Sitzschale zu vermeiden, kann weiterhin bevorzugt vorgesehen sein, dass das erste Drehgelenk ein Verdrehen des Sitzteils relativ zu dem entsprechenden Abschnitt des Gestells um eine in Querrichtung des Stuhls ausgerichtete Drehachse und/oder das zweite Drehgelenk ein Verdrehen der Rückenlehne relativ zu dem entsprechenden Abschnitt des Gestells um eine in Querrichtung des Stuhls ausgerichtete Drehachse ermöglicht.In order to avoid an unfavorable deformation of the seat shell, in particular in the realization of a tilting mobility of the chair, it may further be preferred for the first hinge to rotate the seat part relative to the corresponding section of the frame about an axis of rotation oriented in the transverse direction of the chair and / or second pivot allows rotation of the backrest relative to the corresponding portion of the frame about a rotational axis aligned in the transverse direction of the chair.
Als besonders komfortabel wird möglicherweise empfunden, wenn bei einem Zurückneigen der Rückenlehne gleichzeitig ein Anheben des Sitzteils, insbesondere der Sitzvorderkante des Sitzteils erfolgt. Demnach kann vorzugsweise vorgesehen sein, dass das Gestell derart ausgebildet ist, dass ein Verdrehen des Rückenlehnenträgers um die Drehachse des dritten Drehgelenks zu einer Bewegung der Sitzvorderkante, gegebenenfalls auch des ersten Drehgelenks, in Hochrichtung des Stuhls führt.It may be perceived as particularly comfortable when, at the time of leaning back of the backrest, the seat part, in particular the front edge of the seat part, is raised at the same time. Accordingly, it can preferably be provided that the frame is designed such that a rotation of the backrest support about the axis of rotation of the third pivot joint leads to a movement of the seat leading edge, possibly also of the first pivot, in the vertical direction of the chair.
Diese Funktionalität des Stuhls kann konstruktiv vorteilhaft umgesetzt werden, wenn das Sitzteil, insbesondere über das erste Drehgelenk, an einem Querträger fixiert ist, wobei der Querträger drehbar mit einem Hebel (insbesondere an einem Ende dieses Hebels) und der Hebel (insbesondere an seinem anderen Ende) drehbar mit der Sitzbasis verbunden ist und wobei eine Drehbewegung des Hebels relativ zu der Sitzbasis über eine Stange mit einer Drehbewegung des Rückenlehnenträger um die Drehachse des dritten Drehgelenks gekoppelt ist.This functionality of the chair can be structurally advantageously implemented when the seat part, in particular via the first pivot, is fixed to a cross member, wherein the cross member rotatably with a lever (in particular at one end of this lever) and the lever (in particular at its other end ) is rotatably connected to the seat base and wherein a rotational movement of the lever relative to the seat base is coupled via a rod with a rotational movement of the backrest support about the axis of rotation of the third pivot joint.
Wiederum um den Komfort bei der Nutzung des Stuhls zu verbessern, kann dieser vorzugsweise als Drehstuhl ausgebildet sein, bei dem eine über das erste Drehgelenk mit dem Sitzteil verbundene Sitzbasis des Gestells über ein Drehgelenk mit einem Fußteil des Gestells verbunden ist.Again, to improve the comfort in the use of the chair, this may preferably be formed as a swivel chair, in which a connected via the first pivot to the seat part seat base of the frame is connected via a hinge with a foot part of the frame.
Die Sitzschale des Stuhls kann vorzugsweise integral ausgebildet sein, so dass der Sitzteil und die Rückenlehne (weiterhin bevorzugt einstückig) ineinander übergehen.The seat of the chair may preferably be integrally formed, so that the seat part and the backrest (further preferably in one piece) merge into one another.
Alternativ kann aber auch vorgesehen sein, dass die Sitzschale einen Sitzteil und eine Rückenlehne, die als separate Bauteile ausgebildet sind, sowie einen den Sitzteil und die Rückenlehne verbindenden Rahmen umfasst. Der Rahmen kann vorzugsweise als mittig bezüglich der Querrichtung des Stuhls angeordneter, beispielsweise L-förmiger oder bogenförmig verlaufender Balken ausgebildet sein. Dabei kann weiterhin bevorzugt vorgesehen sein, dass die Deformation der Sitzschale insbesondere von dem Rahmen ermöglicht bzw. aufgenommen wird. Dafür kann beispielsweise eine Ausgestaltung des Rahmens in Form einer (ein- oder mehrschichtigen) Blattfeder vorteilhaft sein. Eine solche Ausgestaltung der Sitzschale des erfindungsgemäßen Stuhls ermöglicht, den Sitzteil und die Rückenlehne als relativ steife Bauteile auszubilden, während der leicht deformierbare Rahmen die Deformierbarkeit der Sitzschale insgesamt bei relativ geringen Kräften gewährleistet.Alternatively, however, it can also be provided that the seat shell comprises a seat part and a backrest, which are designed as separate components, and a frame connecting the seat part and the backrest. The frame may preferably be formed as centrally arranged with respect to the transverse direction of the chair, for example, L-shaped or arcuate extending beams. In this case, it may further be preferred that the deformation of the seat shell is made possible or absorbed, in particular, by the frame. For example, an embodiment of the frame in the form of a (single or multilayer) leaf spring may be advantageous. Such an embodiment of the seat of the chair according to the invention makes it possible to form the seat part and the backrest as relatively rigid components, while the easily deformable frame ensures the deformability of the seat shell overall at relatively low forces.
Ein solcher erfindungsgemäßer Stuhl kann zudem weiter vorteilhaft derart konstruiert sein, dass der Sitzteil in Längsrichtung des Stuhls und/oder die Rückenlehne in Hochrichtung des Stuhls verschiebbar an dem Rahmen gelagert ist/sind. Dabei kann die Verschiebbarkeit nur temporär nach einem Lösen einer Sperrvorrichtung vorgesehen sein. Dies ermöglicht eine möglichst optimale Anpassung der Sitzschale an unterschiedliche Körperdimensionen von Nutzern.Such a chair according to the invention can also be advantageously designed in such a way that the seat part in the longitudinal direction of the chair and / or the backrest in the vertical direction of the chair is / are slidably mounted on the frame. The displacement can be provided only temporarily after a release of a locking device. This allows the best possible adaptation of the seat to different body dimensions of users.

Das Gestell 1 ist im Wesentlichen starr ausgebildet. Dieses ist somit derart ausgelegt, dass es sich bei einer bestimmungsgemäßen Benutzung des Stuhls nicht funktional deformiert. Das Gestell 1 kann einteilig, beispielsweise aus miteinander verschweißten Rohren ausgebildet sein. Es bildet beispielsweise, wie dargestellt, vier Füße aus, über die der Stuhl auf einem Untergrund abstellbar ist.The
Die Sitzschale 2 ist integral ausgebildet, so dass ein als Sitzteil 3 genutzter Abschnitt in einen als Rückenlehne 4 genutzten Abschnitt der Sitzschale 2 übergeht. Dabei kann die Sitzschale 2 ein- oder mehrteilig (insbesondere mit einem dann vorzugsweise einteiligen Sitzschalenoberteil und einem das Sitzschalenoberteil tragenden Rahmen) ausgebildet sein (vgl. auch
Die Sitzschale ist über zwei Drehgelenke 5, 6 mit dem Gestell 1 verbunden. Dabei ist ein erstes Drehgelenk 5 in der Nähe der Sitzvorderkante 7 der Sitzschale 2 angeordnet. Bezüglich der Querrichtung des Stuhls ist das erste Drehgelenk 5 mittig und damit in etwa in der Sagittalebene eines Nutzers des Stuhls positioniert. Das erste Drehgelenk 5 ermöglicht ein Verdrehen des mit diesem Drehgelenk 5 verbundenen Abschnitts der Sitzschale 2, konkret im Wesentlichen des gesamten Sitzteils 3, relativ zu dem entsprechenden Abschnitt des Gestells 1 (der Sitzbasis 8) um eine erste Drehachse 9. Diese erste Drehachse 9 verläuft in Hochrichtung des Stuhls. Konkret ist diese in etwa vertikal (bei auf einem horizontalen Untergrund stehenden Stuhl) ausgerichtet. Das erste Drehgelenk 5 kann derart ausgebildet sein, dass ein mit der Sitzbasis 8 (oder dem Sitzteil 3) verbundener Zapfen 10 drehbar in einem mit dem Sitzteil 3 (oder der Sitzbasis 8) verbundenen Hülse 11 gelagert ist.The seat is connected via two
Ein zweites Drehgelenk 6 verbindet die Sitzschale 2 im Bereich der Rückenlehne 4 mit einem Rückenlehnenträger 12 des Gestells 1. Dabei ist das zweite Drehgelenk 6 mittig bezüglich der Querrichtung des Stuhls und somit - ebenso wie das erste Drehgelenk 5 - in etwa in der Sagittalebene eines Nutzers des Stuhls angeordnet. Das zweite Drehgelenk 6 ist als Kugelgelenk ausgebildet. Dieses ermöglicht demnach ein Verdrehen der Rückenlehne 4 relativ zu dem Rückenlehnenträger 12 um eine Vielzahl von Achsen, unter anderem um mindestens eine sich in Längsrichtung des Stuhls erstreckende zweite Drehachse 13.A
Die erfindungsgemäße Lagerung der Sitzschale 2 ermöglicht eine durch eine Gewichtverlagerung eines Nutzers hervorgerufene Verformung der Sitzschale 2, bei der diese im Übergang von dem Sitzteil 3 zu der Rückenlehne 4 zu einer Seite bewegt wird, während die Sitzvorderkante 7 und die Rückenlehnenkante 14 in Richtung der anderen Seite geneigt werden (vgl.
Der Sitzteil 3 der Sitzschale 2 ist weiterhin noch über zwei Lager 15 mit dem Gestell 1 verbunden. Jeweils ein Lager 15 ist in Querrichtung des Stuhls beabstandet von dem ersten Drehlager 5 angeordnet. Hinsichtlich der Längsrichtung des Stuhls befinden sich die Lager 15 in der Höhe des ersten Drehlagers 5 und der Sitzvorderkante 7. Die beiden Lager 15 sind derart ausgebildet, dass diese zumindest eine Belastung entgegen der Hochrichtung, d.h. von oben nach unten, abstützen, d.h. verhindern. Dadurch wird ein Verdrehen des vorderen Abschnitts des Sitzteils 3 um eine in Längsrichtung des Stuhls ausgerichtete Achse und folglich ein zur Seite Kippen eines Nutzers mitsamt der Sitzschale 2 verhindert. Die Lager 15 sind dabei derart ausgebildet, dass eine Relativbeweglichkeit des Sitzteils 3 zu dem Gestell 1 im Bereich der Lager 15 in einer Ebene, die sich in Längsrichtung und Querrichtung des Stuhls erstreckt, möglich ist (vgl.
Sofern die Lager 15 auch jeweils eine Belastung in Hochrichtung, d.h. von unten nach oben, abstützen sollen, kann vorgesehen sein, dass eines der Lagerteile jedes Lagers 15 ein Langloch ausbildet, durch das sich ein Führungsbolzen des anderen Lagerteils erstreckt, wobei der Rand des Langlochs zumindest einseitig, vorzugsweise zweiseitig in eine von dem Führungsbolzen in seinem Mantel ausgebildete Nut eingreift.If the

Der Rückenlehnenträger 12 ist L-förmig ausgebildet, wobei das freie Ende des einen Schenkels über das zweite Drehgelenk 6 mit der Rückenlehne 4 der Sitzschale 2 und das freie Ende des anderen Schenkels über das dritte Drehgelenk 16 mit der Sitzbasis 8 verbunden ist. Der Rückenlehnenträger 12 kann aber ebenso gut auch bogenförmig ausgebildet sein.The
Um die Neigungsbeweglichkeit der Sitzschale 2 nicht zu behindern, sind das erste Drehgelenk 5 und das zweite Drehgelenk 6 so ausgebildet, dass diese ein Verdrehen des entsprechenden Abschnitts der Sitzschale 2 relativ zu dem entsprechenden Abschnitt des Gestells 1 jeweils auch um eine in Querrichtung des Stuhls ausgerichtete, vierte Drehachse 18 beziehungsweise fünfte Drehachse 19 ermöglichen. Diese Drehbarkeit ergibt sich bei dem zweiten Drehgelenk 6 aus dessen Ausgestaltung als Kugelgelenk. Für das erste Drehgelenk 5 ergibt sich diese Drehbarkeit dagegen aus der Verformbarkeit der Sitzschale, wie dies in den
Durch den Abstand der dritten Drehachse 17 von der von dem ersten Drehgelenk 5 ausgebildeten, sich in Querrichtung des Stuhls erstreckenden vierten Drehachse 18 verändert sich der (direkte) Abstand zwischen der vierten Drehachse 18 und dem zweiten Drehlager 6 bei einem Zurückneigen der Sitzschale 2. Dies führt zu einer Deformation der Sitzschale 2, bei der sich ein zwischen dem Sitzteil 3 und der Rückenlehne 4 ausgebildeter Winkel α vergrößert (α1 < α2).Due to the distance between the third axis of

Dazu ist das dritte Drehgelenk 16, über das der Rückenlehnenträger 12 mit der Sitzbasis 8 verbunden ist, zurückversetzt angeordnet. Zudem sind an demselben Ende wie das dritte Drehgelenk 16 noch zwei (jeweils eines auf jeder Seite des Rückenlehnenträger 12) Stangen 23 um eine siebte Drehachse 24 drehbar mit dem Rückenlehnenträger 12 verbunden. Dabei ist die siebte Drehachse 24 von der von dem dritten Drehlager 16 ausgebildeten dritten Drehachse 17 beabstandet angeordnet.For this purpose, the third rotary joint 16, via which the
Die Stangen 23 erstrecken sich bis zu einem Ende von jeweils einem Hebel 25, mit dem diese um eine sich in Querrichtung des Stuhls erstreckende achte Drehachse 26 drehbar verbunden sind. Das jeweils andere Ende der Hebel 25 ist um eine sich in Querrichtung des Stuhls erstreckende neunte Drehachse 27 drehbar mit der Sitzbasis 8 verbunden. Somit ergibt sich auch ein Abstand zwischen der achten Drehachse 26 und der neunten Drehachse 27. Dabei ist die neunte Drehachse 27 in etwa so positioniert, wie die dritte Drehachse 17 bei dem Stuhl gemäß den
Das erste Drehgelenk 5 ist über einen Querträger mit den beiden Stangen 23 in der Nähe der achten Drehachse verbunden. Dieser kann jedoch auch, wiederum in der Nähe der achten Drehachse, mit den beiden Hebel 25 verbunden sein. Durch diese Anbindung des ersten Drehgelenks 5 in Verbindung mit den Abständen, die zwischen der dritten Drehachse 17 und der siebten Drehachse 24 einerseits sowie der achten Drehachse 26 und der neunten Drehachse 27 andererseits ausgebildet sind, ergibt sich die gewünschte, an eine Neigungsverstellung der Sitzschale 2 gekoppelte Höhenverstellung des ersten Drehlagers 5 und damit der Sitzvorderkante 7.The
