Description

Die Erfindung betrifft ein Sitzmöbel gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a chair according to the preamble of claim 1.

Aus der DE 101 06 792 A1 bzw. der EP 1 230 876 A1 ist ein Sitzmöbel mit einem Sitzelement, einem Rückenelement und einem Traggestell bekannt, wobei das Traggestell einen Träger und ein mechanisches Mittel zur Übertragung einer Bewegung wie Hebel und/oder Führung umfasst, welches den Träger in einem hinteren Sitzbereich mit dem Sitzelement verbindet, wobei als vorderes Befestigungsmittel für das Sitzelement ein Blattfederelement vorgesehen ist, welches an dem feststehenden Träger gelagert ist, wobei das Blattfederelement einen an dem Träger geführten ersten Abschnitt und einen frei zwischen dem Träger und dem Sitzelement liegenden zweiten Abschnitt aufweist. Das Zurücklehnen einer Person auf diesem Sitzmöbel führt zu einem starken Anheben des vorderen Abschnitts des Sitzelements.From the DE 101 06 792 A1 or the EP 1 230 876 A1 a seat comprising a seat member, a back member and a support frame is known, the support frame comprising a support and a mechanical means for transmitting a movement such as lever and / or guide, which connects the carrier in a rear seat with the seat member, wherein as the front Fastening means for the seat element, a leaf spring element is provided, which is mounted on the fixed support, wherein the leaf spring element has a guided on the carrier first portion and a lying between the carrier and the seat member second portion. The reclining of a person on this chair leads to a strong lifting of the front portion of the seat element.

Aus der US 2003/0052520 A1 ist ein ähnliches Sitzmöbel bekannt, bei welchem eine Sitzplatte und ein Sitzplattenträger über Federmittel verbunden sind.From the US 2003/0052520 A1 a similar seating is known in which a seat plate and a seat support plate are connected via spring means.

Aus der JP 08 089359 A ist ein Sitzmöbel mit einem Sitzelement, einem Rückenelement und einem Traggestell bekannt, wobei das Traggestell einen Träger und ein mechanisches Mittel zur Übertragung einer Bewegung umfasst, welches den Träger in einem hinteren Sitzbereich mit dem Sitzelement verbindet, wobei als vorderes Befestigungsmittel für das Sitzelement ein Blattfederelement vorgesehen ist, welches an dem feststehenden Träger gelagert ist, wobei das Blattfederelement einen an dem Träger geführten ersten Abschnitt und einen frei zwischen dem Träger und dem Sitzelement liegenden zweiten Abschnitt aufweist und wobei das Blattfederelement in dem ersten Abschnitt schräg nach oben in Richtung einer Vorderkante des Sitzelements weist.From the JP 08 089359 A is a chair with a seat element, a back member and a support frame known, wherein the support frame a carrier and a mechanical means for transmitting a movement, which connects the carrier in a rear seat with the seat member, wherein as a front fixing means for the seat member, a leaf spring member is provided which is mounted on the fixed support, wherein the leaf spring member guided on the carrier first portion and a second portion lying freely between the carrier and the seat member, and wherein the leaf spring member in the first portion has obliquely upward toward a front edge of the seat member.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln weitere Verstellmöglichkeiten zu realisieren.The invention has for its object to realize with simple means further adjustment.

Diese Aufgabe wird ausgehend von den Merkmalen des Oberbegriffs des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen angegeben.This object is based on the features of the preamble of claim 1 by the characterizing Characteristics of claim 1 solved. In the dependent claims advantageous and expedient developments are given.

Das erfindungsgemäße Sitzmöbel weist ein Blattfederelement auf, welches in einem ersten Abschnitt schräg nach oben in Richtung einer Vorderkante des Sitzelements weist. Diese Ausrichtung des Blattfederelements führt zu einer Bewegungscharakteristik des Sitzelements, bei welcher sich dieses beim Zurücklehnen einer Person in dem Sitzmöbel in einem vorderen Abschnitt leicht anhebt und auch etwa horizontal in Richtung des Rückenelements verlagert. Somit ist es möglich, allein durch eine erfindungsgemäße Schrägstellung des Blattfederelements die Bewegungscharakteristik des Sitzelements in einer gewünschten Weise zu verändern und somit die Hebebewegung, welche das Sitzelement beim Zurücklehnen einer Person in dem Sitzmöbel ausführt, auf eine gewünschte Größe zu begrenzen. Durch die Schrägstellung des Blattfederelements erlaubt dieses auch eine etwa horizontale Bewegung des Sitzelements.The seating furniture according to the invention has a leaf spring element which, in a first section, points obliquely upwards in the direction of a front edge of the seat element. This orientation of the leaf spring element leads to a movement characteristic of the seat element, in which this easily lifts when reclining a person in the seating in a front section and also displaced approximately horizontally in the direction of the back element. Thus, it is possible to change the motion characteristic of the seat member in a desired manner solely by an inventive oblique position of the leaf spring element and thus to limit the lifting movement, which executes the seat member when reclining a person in the chair to a desired size. Due to the inclination of the leaf spring element this also allows an approximately horizontal movement of the seat element.

Erfindungsgemäß ist es vorgesehen, eine Steigung des Blattfederelements in einem Übergangsbereich, welcher zwischen dem ersten und dem zweiten Abschnitt liegt, durch ein unteres Auflager zu verstellen. Hierdurch ist eine Feinjustierung der Grundstellung des Sitzelements mit einfachen technischen Mitteln möglich.According to the invention it is provided to adjust a pitch of the leaf spring element in a transition region, which lies between the first and the second section, by a lower support. As a result, a fine adjustment of the basic position of the seat element by simple technical means is possible.

Insbesondere ist ein Anheben des Blattfederelements in seinem Übergangsbereich durch das untere Auflager vorgesehen, da hierdurch die in einer Grundeinstellung vorhandene Neigung des Sitzelements zu seiner Vorderkante aufgehoben werden kann.In particular, a lifting of the leaf spring element is provided in its transition region through the lower support, since in this way the existing in a basic adjustment inclination of the seat element can be lifted to its front edge.

Weiterhin ist es vorgesehen, das Auflager als Nocke auszubilden, welche um eine Drehachse zentrisch oder exzentrisch drehbar ist. Hierdurch kann mit technisch einfachen Mitteln in unterschiedlicher Weise auf die Voreinstellung Einfluss genommen werden.Furthermore, it is provided to form the support as a cam, which is rotatable about an axis of rotation centric or eccentric. This can be done with technical simple means in different ways to influence the presetting.

Weiterhin ist es vorgesehen, in dem ersten Abschnitt des Blattfederelements ein oberes Gegenlager anzuordnen, welches von oben auf das Blattfederelement wirkt, sofern das obere Gegenlager entlang des ersten Abschnitts des Blattfederelements verfahrbar ist, ist es möglich die Härte des Blattfederelements stufenlos einzustellen und so das Sitzelement für Personen mit unterschiedlichem Körpergewicht anzupassen.Furthermore, it is provided to arrange in the first portion of the leaf spring element, an upper abutment, which acts from above on the leaf spring element, if the upper abutment along the first portion of the leaf spring element is movable, it is possible to adjust the hardness of the leaf spring element and thus the seat element for people with different body weight.

Insbesondere ist es vorgesehen, das obere Gegenlager mit einem Zahnschieber und einem Zahnrad auszustatten, wobei das Blattfederelement zwischen einer Auflagefläche des Trägers und dem Zahnschieber eingeklemmt ist und wobei der Zahnschieber durch eine Drehung des Zahnrads parallel zu der Auflagefläche des Trägers in eine Längsrichtung des Blattfederelements bewegbar ist. Hierdurch ist mit technisch einfachen Mitteln eine stufenlose Einstellbarkeit des Blattfederelements realisierbar.In particular, it is provided to equip the upper counter bearing with an tooth slide and a gear, wherein the leaf spring element is clamped between a bearing surface of the carrier and the tooth slide and wherein the tooth slide by rotation of the gear parallel to the support surface of the carrier in a longitudinal direction of the leaf spring element movable is. As a result, a stepless adjustability of the leaf spring element can be realized with technically simple means.

Weiterhin ist es vorgesehen, durch eine Verlängerung des Hebels, welcher den Träger und das Sitzelement verbindet, einen Rückenelementträger auszubilden, an welchem das Rückenelement befestigt ist. Hierdurch ist eine Bewegungskopplung des Sitzelements mit dem Rückenelement und somit eine Abfederung des Rückenelements über das Blattfederelement möglich.Furthermore, it is provided, by an extension of the lever, which connects the carrier and the seat member to form a back element carrier, on which the back element is attached. As a result, a movement coupling of the seat element with the back element and thus a cushioning of the back element via the leaf spring element is possible.

Schließlich sieht die Erfindung eine Fixierbarkeit des Hebels in wenigstens zwei Drehstellungen an dem Träger vor. Hierdurch ist es möglich das Sitzelement und das Rückenelement in bevorzugten Stellungen zu arretieren.Finally, the invention provides a fixability of the lever in at least two rotational positions on the carrier. This makes it possible to lock the seat element and the back member in preferred positions.

Weitere Einzelheiten der Erfindung werden in der Zeichnung anhand von schematisch dargestellten Ausführungsbeispielen beschrieben.Further details of the invention are described in the drawing with reference to schematically illustrated embodiments.

Der Hebel 11 verbindet den Träger 8 mit dem hinteren Sitzbereich 13 des Sitzelements 2. Der Hebel 11 ist an dem Träger 8 drehbar um eine Drehachse D118 befestigt. Das Sitzelement 2 ist an dem Hebel 11 drehbar um eine Drehachse D112 befestigt. Weiterhin ist zwischen dem Träger 8 und dem Hebel 11 ein Rastmechanismus 28 vorgesehen, durch welchen eine Drehbarkeit des Hebels 11 um die Drehachse D118 blockierbar ist.The FIG. 2 show the FIG. 1 in the region of the support frame 4 in an enlarged view. The leaf spring element 9 consists of eight individual leaf springs 9a to 9h with partially different lengths. Furthermore, the leaf spring element 9 has a first, right section A and a second, left section B on. In the first section A, the leaf spring element 9 is clamped between a support surface 8 formed on the support surface 17 and a toothed slide 18 and thus fixed to the support 8. The section A of the leaf spring element 8 has obliquely upwards in the direction of the front edge 19 of the seat element 2 and is in this case at an angle y = 18 ° to a further horizontal 20. The toothed slide 18 is arranged by rotation of this driving and fixed to the support 8 Gear 21 in the direction of arrow v or v 'movable. As a result, a hardness of the leaf spring element 9 is adjustable. In the second, left section B, the leaf spring element 9 extends approximately bent by 90 °. The leaf spring element 9 is fastened to a free end 22 with a sleeve 23 rotatably mounted on the seat element 2 about a rotation axis D23 with a screw 24. In a transition region C of the leaf spring element 9, which between the two sections A and B, a support 25 is disposed on the carrier 8. This is formed by a cam 26, which is fastened to the carrier 8 rotatably about a rotation axis D26. By this support 25, the leaf spring element 9 can be raised and allows an adjustment of the inclination of the seat member 2. The toothed slider 18 and the gear 21 form an upper abutment 27 to this support 25. In the FIG. 4 5, the cam 26 is shown, for example, in a position in which it raises the leaf spring element 9. The lever 11 connects the carrier 8 with the rear seat portion 13 of the seat member 2. The lever 11 is fixed to the carrier 8 rotatably about a rotation axis D118. The seat member 2 is rotatably attached to the lever 11 about a rotation axis D112. Furthermore, a latching mechanism 28 is provided between the carrier 8 and the lever 11, through which a rotation of the lever 11 about the rotational axis D118 can be blocked.

Sofern der Hebel 11 in der in der Figur 1 und der Figur 2 gezeigten Stellung 29 durch den Rastmechanismus 28 an dem Träger 8 fixiert ist, bewirkt eine Belastung des Sitzelements 2 mit einer Gewichtskraft G einer auf dem Sitzmöbel 1 sitzenden, nicht dargestellten Person ein Absinken des Sitzelements 2 mit seinem vorderen Sitzbereich 12 in eine Pfeilrichtung y' gegen das Blattfederelement 9. Hierbei dreht sich das Sitzelement 2 um seine Drehachse D112 nach links. Das Blattfederelement 9 bewirkt eine Gegenkraft gegen die durch die Gewichtskraft G bewirkte Drehbewegung bis ein Kräftegleichgewicht hergestellt ist.If the lever 11 in the in the FIG. 1 and the FIG. 2 shown position 29 is fixed by the latching mechanism 28 to the support 8, causes a load of the seat member 2 with a weight G sitting on the chair 1, not shown a drop in the seat element 2 with its front seat area 12 in an arrow y 'against the leaf spring element 9. In this case, the seat element 2 rotates about its axis of rotation D112 to the left. The leaf spring element 9 causes a counterforce against the rotational force caused by the weight G until a balance of forces is established.

Mittels des Rastmechanismus 28, welcher in eine der dargestellten Bohrungen 40 einrasten kann, können unterschiedliche Positionen des Sitzelements 2 bzw. des Rückenelements 3 vorgewählt und fixiert werden.By means of the latching mechanism 28, which can engage in one of the bores 40 shown, different positions of the seat element 2 and the back element 3 can be preselected and fixed.

Sofern der Hebel 11 in der in der Figur 1 und der Figur 2 gezeigten Stellung 29 nicht an dem Träger 8 fixiert ist, bewirkt eine Belastung des Sitzelements 2 mit der Gewichtskraft G der auf dem Sitzmöbel 1 sitzenden, nicht dargestellten Person eine Bewegung des Sitzelements 2. Hierbei ist die Bewegung davon abhängig, wie die resultierende Gewichtskraft in dem vorderen oder hinteren Sitzbereich 12 bzw. 13 auf das Sitzelement 2 wirkt. Sofern die resultierende Gewichtskraft in Pfeilrichtung x' vor der Drehachse D23 auf das Sitzelement 2 wirkt, stellt sich im wesentlichen die oben beschriebene Drehbewegung des Sitzelements 2 um die Drehachse D112 ein, da sich der Hebel 11 nur nach rechts um das Drehlager D118 drehen kann, weil eine Drehung nach links ist durch einen nur in der Figur 2 dargestellten Anschlag 30 an dem Träger 8 blockiert. Sofern die Resultierende der Gewichtskraft G zum Beispiel in dem hinteren Sitzbereich 13 des Sitzelements 2 angreift, sinkt das Sitzelement 2 mit seinem hinteren Sitzbereich 13 in die Pfeilrichtung y' ab. Hierbei bewegt sich das Sitzelement 2 mit der Drehachse D112 im Uhrzeigersinn auf einer Kreisbahn 31 um die Drehachse D118. Durch diese Drehbewegung wird das an der Welle 23 des Sitzelements 2 befestigte Blattfederelement 9 etwa in eine Pfeilrichtung x gezogen. Diese Zugbelastung bewirkt eine Bewegung des Sitzelements 2 mit seiner Drehachse D23 beispielsweise auf einer bogenförmigen Bewegungsbahn 32, deren Steigung kontinuierlich abnimmt. Das Sitzelement 2 folgt dieser Bewegungsbahn 32 bis sich wieder ein Kräftegleichgewicht einstellt.If the lever 11 in the in the FIG. 1 and the FIG. 2 shown position 29 is not fixed to the support 8, causes a load of the seat member 2 with the weight G of sitting on the chair 1, not shown a movement of the seat element 2. Here, the movement is dependent on how the resulting weight in the front or rear seating area 12 or 13 acts on the seat element 2. If the resulting weight acts on the seat element 2 in the direction of arrow x 'in front of the axis of rotation D23, essentially the above-described rotational movement of the seat element 2 is established about the axis of rotation D112, since the lever 11 can only turn to the right about the rotary bearing D118, because a turn to the left is by one only in the FIG. 2 shown stop 30 is blocked on the support 8. If the resultant force of the weight G engages, for example, in the rear seating area 13 of the seat element 2, the seat element 2 with its rear seating area 13 drops in the direction of the arrow y '. Here, the seat member 2 moves with the rotation axis D112 in a clockwise direction on a circular path 31 about the rotation axis D118. As a result of this rotational movement, the leaf spring element 9 fastened to the shaft 23 of the seat element 2 is pulled approximately in an arrow direction x. This tensile load causes a movement of the seat member 2 with its axis of rotation D23, for example, on an arcuate path of movement 32, the slope decreases continuously. The seat element 2 follows this movement path 32 until a balance of forces is established again.

Die Figur 3 zeigt eine Unteransicht des in der Figur 1 gezeigten Sitzmöbels 1 aus einer Pfeilrichtung III. In der Unteransicht ist ein erster Drehgriff 33 erkennbar, durch welchen die Nocke 26, welche das Auflager 25 für das Blattfederelement 9 bildet, verdrehbar ist. Weiterhin zeigt die Unteransicht einen zweiten Drehgriff 34, mit welchem das Zahnrad 21 verdrehbar ist, welches den Zahnschieber 18 antreibt. An dem Hebel 11, welcher als Gabel 35 ausgebildet ist und zwei Arme 35a und 35b aufweist ist ein Raststift 36 angeordnet, welcher den Rastmechanismus 28 bildet und in Pfeilrichtungen z bzw. z' verschiebbar ist. Der Raststift 36 ist in einer ersten Stellung 37 und in einer zweiten Stellung 38 dargestellt. In der zweiten Stellung 38 greift der Raststift 36 mit einer Nase 39 in die Bohrung 40 ein, welche an dem Träger 8 ausgebildet ist. Hierdurch ist eine Drehbarkeit des Hebels 9 um die Drehachse D118 blockiert. In der erste Stellung 37 ist der Raststift 36 in die Pfeilrichtung z zurückgezogen und steht mit seiner Nase 39 außerhalb des Trägers 8 und kann sich somit frei um seine Drehachse D118 drehen.The FIG. 3 shows a bottom view of the in FIG. 1 shown seat furniture 1 from an arrow III. In the bottom view, a first rotary handle 33 can be seen, through which the cam 26, which forms the support 25 for the leaf spring element 9, is rotatable. Furthermore, the bottom view shows a second rotary handle 34, with which the gear 21 is rotatable, which the tooth slide 18th drives. On the lever 11, which is designed as a fork 35 and has two arms 35a and 35b, a latching pin 36 is arranged, which forms the latching mechanism 28 and in the directions of the arrow z or z 'is displaceable. The locking pin 36 is shown in a first position 37 and in a second position 38. In the second position 38, the locking pin 36 engages with a nose 39 in the bore 40, which is formed on the carrier 8. As a result, a rotation of the lever 9 is blocked about the rotation axis D118. In the first position 37, the locking pin 36 is retracted in the direction of arrow z and stands with its nose 39 outside of the carrier 8 and thus can rotate freely about its axis of rotation D118.

In Figur 4 ist das aus den Figuren 1 bis 3 bekannte Sitzmöbel 1 in einer zweiten Stellung SII in Seitenansicht dargestellt. Durch eine Drehung der Nocke 26 um etwa 90° im Uhrzeigersinn ist das Sitzelement 2 nun gegenüber der in der Figur 1 gezeigten Stellung SI bis in die Horizontale 16 auf einen Neigungswinkel α = 0° angehoben. Der Hebel 11 ist nicht mit dem Träger 8 gekoppelt und hat sich in Folge der Verstellung des Auflagers 25 um seine Drehachse D118 gegenüber seiner in der Figur 1 gezeigten Stellung leicht nach rechts gedreht. Der Öffnungswinkel β zwischen dem Sitzelement 2 und dem Rückenelement 3 liegt in dieser Stellung SII genauso wie in der Stellung SI bei etwa 80°.In FIG. 4 is that from the FIGS. 1 to 3 known seating 1 in a second position SII shown in side view. By a rotation of the cam 26 by about 90 ° clockwise, the seat element 2 is now opposite to in the FIG. 1 shown position SI raised to the horizontal 16 to an inclination angle α = 0 °. The lever 11 is not coupled to the carrier 8 and has as a result of the adjustment of the support 25 about its axis of rotation D118 relative to its in the FIG. 1 shown slightly rotated to the right. The opening angle β between the seat member 2 and the back member 3 is in this position SII as well as in the position SI at about 80 °.

In der Figur 5, welche eine vergrößerte Darstellung der Figur 4 im Bereich des Traggestells 4 zeigt, ist erkennbar, wie die Nocke 26 das Blattfederelement 9 in einem Übergangsbereich C verformt und von der Auflagefläche 17 abhebt.In the FIG. 5 , which is an enlarged view of FIG. 4 shows in the region of the support frame 4, it can be seen how the cam 26, the leaf spring element 9 deformed in a transition region C and lifts from the support surface 17.

In der Figur 6 ist das aus den Figuren 1 bis 5 bekannte Sitzmöbel 1 in einer dritten Stellung SIII in Seitenansicht dargestellt. Die dritte Stellung SIII ergibt sich aus der in den Figuren 4 und 5 gezeigten Stellung SII durch die Belastung des Sitzmöbels 1 mit der Gewichtskraft einer nicht dargestellten Person, wobei sich die nicht dargestellte Person auch gegen das Rückenelement 3 lehnt. Auf die beschriebene Belastung reagiert das Sitzmöbel 1 durch Bewegungen des Sitzelements 2 und des Rückenelements 3 in die Pfeilrichtung x, wobei sich hierbei das Sitzelement 2 mit seinem vorderen Sitzbereich 12 anhebt und mit seinem hinteren Sitzbereich 13 absenkt und wobei sich das Rückenelement 3 auch an dem Hebel 11 um die Drehachse D118 nach rechts dreht. Somit verändert sich neben der Ausrichtung des Sitzelements 2 und des Rückenelements 3 auch der Öffnungswinkel β zwischen dem Sitzelement 2 und dem Rückenelement 3. In der Stellung SIII des Sitzmöbels 1 weist der Öffnungswinkel β einen Wert von etwa 95° auf.In the FIG. 6 is that from the FIGS. 1 to 5 known seating 1 in a third position SIII shown in side view. The third position SIII results from the in the FIGS. 4 and 5 shown position SII through the Load of the chair 1 with the weight of a person, not shown, wherein the person not shown also leans against the back member 3. On the described burden, the chair 1 reacts by movements of the seat member 2 and the back member 3 in the direction of arrow x, in which case the seat member 2 lifts with its front seat 12 and lowers with its rear seat 13 and wherein the back member 3 also on the Lever 11 rotates about the axis of rotation D118 to the right. Thus, apart from the orientation of the seat element 2 and the back element 3, the opening angle β between the seat element 2 and the back element 3 also changes. In the position SIII of the seat 1, the opening angle β has a value of approximately 95 °.

In der Figur 7 ist das aus den Figuren 1 bis 6 bekannte Sitzmöbel 1 in seinen beiden Stellungen SII und SIII in einer überlagerten Darstellung im Bereich des Traggestells 4 gezeigt. In der überlagerten Darstellung ist erkennbar wie durch die Verformung des Blattfederelements 9 und die Drehung des Hebels 11 um die Drehachse D118 das Sitzelement 2 aus einer waagrechten Stellung in eine zu dem Rückenelement 3 abfallende Stellung verschoben wird und sich hierbei mit seiner Vorderkante 19 anhebt und seinem hinteren Sitzbereich 13 absenkt. Hierzu bewegt sich die Drehachse D23 von einem Punkt P1 zu einem Punkt P2 und die Drehachse D112 von einem Punkt P3 zu einem Punkt P4. Selbstverständlich ist der Hebel 11 bei diesem Bewegungsvorgang, welcher durch die Gewichtskraft der auf dem Sitzmöbel 1 sitzenden, nicht dargestellten Person hervorgerufen wird, nicht an dem Träger 8 arretiert. Das Sitzelement 2 bewegt sich also zwischen einem vorderen Befestigungsmittel 41, welches im wesentlichen durch das Blattfederelement 9 gebildet wird, und einem hinteren Befestigungsmittel 42, welches im wesentlichen durch ein mechanisches Mittel 10 zur Übertragung einer Bewegung gebildet wird, das als Hebel 11 ausgeführt ist. Das hintere Befestigungsmittel 42 erlaubt dem Sitzelement 2 entweder die Bewegung auf einer Kreisbahn 31 um die Drehachse D118 bei ggf. gleichzeitiger Drehung um die Drehachse D112 oder eine reine Drehung um die Drehachse D118. Das vordere Befestigungsmittel 41 begrenzt eine Verstellung des Sitzelements 2, wobei sich die Position der Drehachse D23 an welcher das vordere Befestigungselement 41 und das Sitzelement 2 miteinander verbunden sind ebenfalls verändern kann und wobei grundsätzlich eine Drehung des Sitzelements 2 um die Drehachse D23 möglich ist. Die Stellung des Rückenelements 3 wird durch die Stellung des hinteren Befestigungselements 42 bestimmt, da das Rückenelement 3 an diesem angelenkt ist.In the FIG. 7 is that from the FIGS. 1 to 6 known seating 1 shown in its two positions SII and SIII in a superimposed representation in the region of the support frame 4. In the superimposed representation it can be seen how the seat element 2 is displaced from a horizontal position into a sloping position to the back element 3 by the deformation of the leaf spring element 9 and the rotation of the lever 11 about the axis of rotation D118 and thereby lifts with its front edge 19 and its lower seating area 13 lowers. For this purpose, the rotation axis D23 moves from a point P1 to a point P2, and the rotation axis D112 moves from a point P3 to a point P4. Of course, the lever 11 is not locked to the support 8 in this movement process, which is caused by the weight of sitting on the chair 1, not shown person. The seat member 2 thus moves between a front attachment means 41, which is essentially formed by the leaf spring element 9, and a rear attachment means 42, which is essentially formed by a mechanical means 10 for transmitting a movement, which is designed as a lever 11. The back Fastener 42 allows the seat member 2 either the movement on a circular path 31 about the axis of rotation D118 with possibly simultaneous rotation about the axis of rotation D112 or a pure rotation about the axis of rotation D118. The front fastening means 41 limits an adjustment of the seat member 2, wherein the position of the rotation axis D23 at which the front fastening element 41 and the seat member 2 are connected to each other can also change and wherein in principle a rotation of the seat member 2 about the rotation axis D23 is possible. The position of the back element 3 is determined by the position of the rear fastening element 42, since the back element 3 is articulated thereto.
