Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft einen Stuhl mit neigbarem Sitz und einer neigbaren, von einem Lehnenträger getragenen Lehne. Solche Stühle sind wichtig nicht nur für den Bürobereich, wo der Benutzer den Stuhl unter ergonomischen Aspekten seiner jeweiligen Arbeitsstellung anpassen können muss, sondern auch im privaten Bereich, wo der Benutzer die jeweilige Sitz- und Lehnenneigung zum Zwecke der Entspannung ändern möchte.The invention relates to a chair with a tiltable seat and a tiltable, of a backrest worn backrest. Such chairs are important not only for the office area where the user takes the chair from an ergonomic point of view must be able to adapt to their respective working position, but also in private area where the user can adjust the respective seat and backrest angle Want to change purposes of relaxation.

STAND DER TECHNIKSTATE OF THE ART

Stühle mit neigbarem Sitz und neigbarer Lehne sind zum Beispiel aus EP-A 0834271, EP-B 0489961 oder EP-B 0233974 bekannt. Die aus diesen Druckschriften bekannten Stühle weisen neigbare Sitze und Lehnen auf, wobei Sitz und Lehne zwangsgekoppelt sind. Man spricht insoweit auch von "Synchronmechanik".For example, chairs with a reclining seat and reclining backrest are made of EP-A 0834271, EP-B 0489961 or EP-B 0233974 are known. The one from these Known chairs have tiltable seats and backrests, whereby Seat and backrest are positively coupled. In this respect one also speaks of "Synchronizing mechanism".

Diese Stühle haben sich an sich in der Praxis hervorragend bewährt. Sie sind jedoch insoweit noch nicht optimal, als der Benutzer an das durch die Synchronmechanik vorgegebene Neigungsverhältnis von Sitz und Lehne gebunden ist. Es ist dem Benutzer nicht möglich, die Lehnenneigung in einer bestimmten Stellung einzustellen, und bei einer solchen Stellung die Neigung des Sitzes zu verändern.These chairs have proven to be excellent in practice. they are however, not yet optimal in so far as the user thinks of the Synchronous mechanism predefined inclination ratio of seat and backrest is bound. It is not possible for the user to adjust the backrest angle in one set certain position, and in such a position the inclination to change the seat.

Hier soll die Erfindung Abhilfe bringen. The invention is intended to remedy this.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist demnach die Aufgabe der Erfindung, einen Stuhl mit neigbarem Sitz und neigbarer Lehne derart weiter zu verbessern, dass die Neigung des Sitzes unabhängig von der durch eine Synchronmechanik in Abhängigkeit von der Lehnenneigung gegebenen Neigung individuell eingestellt werden kann. Dabei muss die erfindungsgemäße Konstruktion wenig aufwendig und im Produktionsprozess leicht herstellbar sein, und muss des weiteren auch optischästhetisch voll befriedigen.It is therefore the object of the invention to provide a chair with a tiltable seat reclining backrest to further improve the inclination of the seat regardless of the by a synchronous mechanism depending on the The inclination of the backrest can be adjusted individually. there the construction according to the invention must be inexpensive and The production process must be easy to manufacture, and must also be aesthetically pleasing fully satisfy.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.This object is achieved by the features of claim 1 and Subclaims resolved.

Der Kern der Erfindung besteht in der Idee, bei der Abstützung des Sitzes auf dem Lehnenträger die Distanz zwischen Sitz und Lehnenträger durch eine einfache Exzenterlagerung von Hand veränderbar zu machen. Damit folgt zwar der Sitz prinzipiell der Neigung der Lehne, kann aber in einer festen Position der Lehne hinsichtlich seiner Neigung zusätzlich noch individuell eingestellt werden.The essence of the invention resides in the idea of supporting the seat the backrest support by a distance between the seat and backrest support make simple eccentric bearings changeable by hand. With that follows the seat principally inclines the backrest, but can be in a fixed position The backrest can also be individually adjusted with regard to its inclination.

    • WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

    Die Hauptbestandteile des in Fig.1 und Fig. 2 gezeigten Stuhles sind der Sitz 1, die Lehne 2 mit Lehnenträger 5, die Neigemechanik im Gehäuse 4, und die Standsäule 3. The main components of the chair shown in Fig. 1 and Fig. 2 are the seat 1, the backrest 2 with backrest support 5, the tilt mechanism in the housing 4, and the Stand column 3.

    Sitz 1 und Lehnenträger 5 mit Lehne 2 sind über die Neigemechanik im Gehäuse 4 und die gelenkige Anbindung des Sitzes 1 an den Lehnenträger 5 in bekannter Weise bzgl. ihrer Neigung zwangsgekoppelt. Wenn also die Lehne 2 und mit ihr der Lehnenträger 5 nach hinten geneigt wird, so senkt sich auch der Sitz 1 ab.Seat 1 and backrest support 5 with backrest 2 are in the tilt mechanism Housing 4 and the articulated connection of the seat 1 to the backrest support 5 in in a known manner with respect to their inclination. So if the backrest 2 and with it the backrest support 5 is inclined backwards, so does the lowering Seat 1 from.

    Die gelenkige Anbindung des Sitzes 1 an den Lehnenträger 5 besteht nun aber erfindungsgemäß aus den Elementen 6-16, die im Detail in Fig.3 und Fig.4 gezeigt sind:The articulated connection of the seat 1 to the backrest support 5 now exists according to the invention from the elements 6-16, which are shown in detail in FIG. 3 and FIG are shown:

    An der Unterseite des Sitzes 1 ist ein Lagerbock 10 vorgesehen, in welchem eine Exzenterscheibe 9 drehbar gelagert ist. Die Exzenterscheibe 9 wird exzentrisch von einem Stab 8 durchtreten, der mit der Exzenterscheibe 9 undrehbar verbunden ist, und der an seinem äußeren Ende einen Handgriff 7 aufweist, mit dem er gedreht werden kann. Der Stab 8 ist des weiteren in einem (nicht gezeichneten) Lager 11 gelagert, sowie in dem in Fig.1 und Fig. 2 gezeigten Arm 6, der am Lehnenträger 5 befestigt ist.On the underside of the seat 1, a bearing block 10 is provided, in which an eccentric disc 9 is rotatably mounted. The eccentric 9 eccentrically pass through a rod 8 which is connected to the eccentric disc 9 is non-rotatably connected, and a handle 7 at its outer end with which it can be rotated. The rod 8 is also in one Bearing 11 (not shown) stored, as well as in the in Fig. 1 and Fig. 2nd shown arm 6, which is attached to the backrest support 5.

    Die unverdrehbare Verbindung des Stabes 8 mit der Exzenterscheibe 9 und dem Handgriff 7 wird durch die Ausbildung des Stabes 8 und der von ihm durchtretenen Ausnehmungen als Sechskant erreicht.The non-rotatable connection of the rod 8 with the eccentric 9 and the handle 7 is formed by the formation of the rod 8 and of him Recesses reached as a hexagon.

    Wie insbesondere aus Fig.1 und Fig.2 ersichtlich, kann durch Drehen des Handgriffs 7 das Lager des Stabes 8 im Arm 6 mehr nach oben (Fig.1) oder mehr nach unten (Fig.2) bewegt werden. Dadurch wird die Neigung des Sitzes 1 bei feststehender Neigung der Lehne 2 flacher (Fig.1) oder steiler (Fig.2).As can be seen in particular from FIG. 1 and FIG. 2, by rotating the Handle 7, the bearing of the rod 8 in the arm 6 more up (Fig.1) or more down (Fig. 2). As a result, the inclination of the seat 1 with a fixed inclination of the backrest 2 flatter (Fig.1) or steeper (Fig.2).

    Es ist nun aber zu berücksichtigen, dass bei einer Position des Stabes 8 im Lager des Armes 6 in der unteren Stellung (Fig.2) das Gewicht des Benutzers die Exzenterscheibe 9 nach oben drücken würde, wenn nicht besondere Gegenmaßnahmen vorgesehen würden.However, it must now be taken into account that with a position of the rod 8 in the Bearing the arm 6 in the lower position (Fig.2) the weight of the user the eccentric 9 would push up if not special Countermeasures would be provided.

    Diese Gegenmaßnahmen bestehen darin, dass die Exzenterscheibe 9 an ihrer Mantelfläche eine Nase 13 aufweist, die in der unteren Stellung des Stabes 8 an dem Anschlag 12 im Lagerbock 10 anliegt. Dabei ist der Anschlag 12 im Lagerbock 10 in Bezug auf den tiefsten Lagerpunkt der Nase 13 um mehr als 180° versetzt, liegt also jenseits des oberen Totpunktes. Das bewirkt, dass von der Gewichtskraft des Benutzers keine Komponente entstehen kann, die in Richtung des oberen Totpunktes wirkt, und die Exzenterscheibe 9 nach unten drehen könnte.These countermeasures are that the eccentric 9 on their Shell surface has a nose 13 which in the lower position of the rod 8 the stop 12 rests in the bearing block 10. The stop 12 is in the Bearing block 10 with respect to the lowest bearing point of the nose 13 by more than Offset 180 °, is therefore beyond the top dead center. That causes from the weight of the user, no component can arise that in Direction of top dead center, and the eccentric 9 down could turn.

    In Fig.3 und Fig.4 ist im übrigen noch die konstruktive Ausgestaltung der Exzenterscheibe 9 näher dargestellt: sie weist vier Sechskant-Ausnehmungen 15 auf, und trägt vorn eine Frontplatte 14, die nur eine solche Ausnehmung aufweist. An der Frontplatte 14 ist auch die Nase 13 vorgesehen. Der Handgriff 7 weist die Sechskant-Ausnehmung 16 auf. Wie ersichtlich, kann damit der Stab 8 durch die Ausnehmung 15 der Exzenterscheibe 9 geführt werden, die mit der Ausnehmung in der Frontplatte 14 korrespondiert. Die Nase 13 liegt dann dieser Ausnehmung gegenüber. An seinem Ende wird der Stab 8 in die Ausnehmung 16 des Handgriffs 7 gesteckt.In Fig.3 and Fig.4 is the structural design of the Eccentric disc 9 shown in more detail: it has four hexagonal recesses 15 on, and carries a front panel 14, which has only one such recess having. The nose 13 is also provided on the front plate 14. The handle 7 has the hexagon recess 16. As can be seen, the rod can 8 are guided through the recess 15 of the eccentric 9, which with the Recess in the front panel 14 corresponds. The nose 13 is then this Recess opposite. At its end, the rod 8 is in the recess 16 of the handle 7 inserted.
