Definitions
- the invention relates to a chair according to the preamble of claim 1.
- the invention has for its object to design a chair of the type presupposed as known so that the position and inclination of the front seat part are changed with a changed backrest inclination and, moreover, when pivoting the backrest a substantially constant distance from the Rear edge of the rear seat part is observed.
- the chair according to the invention ensures that the distance of the seat from the backrest remains practically the same over the entire swivel range.
- the lower chair part 2 is designed as a chair column.
- the chair seat consists of a front seat part 6 and a rear seat part 8 pivotally connected to the rear end thereof via a joint.
- the front seat part is connected via a bearing 9 to a link 11 which is connected to the seat support 1 via a bearing 10.
- a force accumulator 13 engages on the bearing 9, and its other end is connected to the seat support 1 via the bearing 13a.
- the rear seat part 8 is designed in its basic form as an angle lever and has an extension 8a which is articulated via a bearing 12 on the seat support 1 or on the upper region of the chair base frame 2. Between the joint 7 and the bearing 12, a bearing 17 is provided, on which a link 16 is articulated.
- the handlebar 16 is connected via a bearing 15 to an upwardly projecting area 14 of the backrest support 3.
- the backrest support 3 is designed in the area of the bearing 5 as an angle lever.
- the backrest and the seat pivoted synchronously therewith can be locked in any desired pivoting position.
- the bearing 12 of the extension 8a of the rear seat part 8 lies behind the central axis 2a of the lower chair part 2 formed by a central column.

Description
- Die Erfindung betrifft einen Stuhl nach dem Oberbegriff des Anspruchs 1.
- Bei einem bekannten Stuhl dieser Art (EP-A 0 105 955) ist der vordere Sitzteil starr mit dem Sitzträger verbunden. Dieser Sitzteil bleibt also unabhängig von der Neigung der Rückenlehne stets in der gleichen Position. Dies hat einerseits die Folge, daß der angestrebte Komfort nur innerhalb. eines vergleichsweise kleinen Gesamtverstellbereichs gewährleistet ist, nämlich in demjenigen Bereich, bei dem die feste Position des vorderen Sitzteils mit den variablen Verstellpositionen des hinteren Sitzteils und der Rückenlehne harmoniert. Andererseits ergibt sich bei der bekannten Konstruktion das Problem, daß sich beim Verschwenken der Rückenlehne deren Abstand von der Hinterkante des hinteren Sitzteils stets verändert.
- Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Stuhl der als bekannt vorausgesetzten Art so auszubilden, daß mit veränderter Rückenlehnenneigung auch die Lage und Neigung des vorderen Sitzteils verändert werden und darüberhinaus beim Verschwenken der Rückenlehne ein im wesentlichen gleichbleibender Abstand von der Hinterkante des hinteren Sitzteils eingehalten wird.
- Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Kennzeichnungsteils von Anspruch 1.
- Der erfindungsgemäße Stuhl stellt sicher, daß der Abstand des Sitzes von der Rückenlehne praktisch über den gesamten Schwenkbereich gleich bleibt.
- Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.
- Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung im einzelnen beschrieben. Es zeigen:
- Figur 1 - eine schematische Seitenansicht eines Stuhloberteils mit der Rückenlehne in einer vorderen Position,
- Figur 2 - die Darstellung gemäß Figur 1 mit der Rückenlehne in einer nach hinten geneigten Position.
- An einem Sitzträger 1, der mit einem Stuhlunterteil 2 fest verbunden ist, ist ein Rückenlehnenträger 3 mit der Rückenlehne 4 im Schwenklager 5 schwenkbeweglich befestigt. Im dargestellten Ausführungsbeispiel ist das Stuhlunterteil 2 als Stuhlsäule ausgebildet.
- Der Stuhlsitz besteht aus einem vorderen Sitzteil 6 und einem über ein Gelenk an dessen hinterem Ende schwenkbeweglich damit verbundenen hinteren Sitzteil 8.
- Der vordere Sitzteil ist über ein Lager 9 mit einem Lenker 11 verbunden, der über ein Lager 10 mit dem Sitzträger 1 verbunden ist. Am Lager 9 greift das eine Ende eines Kraftspeichers 13 an, der mit seinem anderen Ende über das Lager 13a mit dem Sitzträger 1 verbunden ist.
- Der hintere Sitzteil 8 ist in seiner Grundform als Winkelhebel ausgebildet und besitzt einen Ansatz 8a, der über ein Lager 12 am Sitzträger 1 bzw. am oberen Bereich des Stuhluntergestells 2 angelenkt ist. Zwischen dem Gelenk 7 und dem Lager 12 ist ein Lager 17 vorgesehen, an dem ein Lenker 16 angelenkt ist. Der Lenker 16 ist über ein Lager 15 mit einem nach oben ragenden Bereich 14 des Rückenlehnenträgers 3 verbunden.
- Der Rückenlehnenträger 3 ist im Bereich des Lagers 5 als Winkelhebel ausgebildet.
- Beim Verschwenken der Rückenlehne 4 aus der Position gemäß Figur 1 in eine nach hinten geneigte Lage senkt sich der hintere Sitzteil 8 ab.
- Durch Arretierung des Kraftspeichers 13, der im dargestellten Ausführungsbeispiel eine Gasfeder ist, können die Rückenlehne und der synchron damit verschwenkte Sitz in jeder gewünschten Schwenkposition arretiert werden.
- Das Lager 12 des Ansatzes 8a des hinteren Sitzteils 8 liegt hinter der Mittelachse 2a des durch eine Mittelsäule gebildeten Stuhlunterteils 2. Das Lager 5 des Rückenlehnenträgers 3 am Sitzträger 1 liegt vor dieser Mittelachse 2a.
