Abstract
Description
Die Erfindung betrifft das Gebiet der Sitzmöbel, insbesondere eine Rückenlehne für einen Büro-Stuhl, bei welchem die Lehne kardanisch und über Federelemente gestützt am Lehnenträger gelagert ist.The invention relates to the field of seating, in particular a backrest for an office chair, in which the back is gimbaled and supported by spring elements on the backrest support.
Es ist bekannt, bei Bürostühlen die Lehne an den Lehnenträger derart anzubinden, dass sie möglichst allen Bewegungen des Rückens des Benutzers zu folgen vermag. Technisch heißt das, dass die Lehne kardanisch gelagert, also um die drei Raumachsen beweglich ist. Damit kann sie sagittalen Bewegungen des Rückens , also Bewegungen um eine Horizontalachse parallel zum Körper, aber auch Torsionsbewegungen und Transveralbewegungen, also Bewegungen um die Vertikalachse bzw. um eine Horizontalachse senkrecht zum Körper, folgen. Derartige kombinierte Oberkörperbewegungen in drei Richtungen kommen in der Praxis sehr häufig vor, zum Beispiel beim Griff seitlich unten in die Schublade eines Schreibtisches, oder beim Hinwenden zu einem Gesprächspartner. Kardanische Lager für Lehnen bei Stühlen werden auch als "dorsokinetisch flexible Gelenke" bezeichnet.It is known in office chairs to connect the backrest to the backrest support in such a way that it is able to follow as far as possible all movements of the back of the user. Technically, this means that the back is gimbal-mounted, so it is movable around the three spatial axes. It can thus follow sagittal movements of the back, ie movements about a horizontal axis parallel to the body, but also torsional movements and transversal movements, ie movements about the vertical axis or about a horizontal axis perpendicular to the body. Such combined upper body movements in three directions are very common in practice, for example, the handle side down in the drawer of a desk, or when turning to a conversation partner. Gimbals for chairs in chairs are also called "dorsokinetically flexible joints".
Ein Stuhl der geschilderten Art ist z.B. aus der EP-A 0308538 bekannt. Bei diesem bekannten Stuhl wird die kardanische Lagerung dadurch erreicht, dass die Lehne eine kugelsegmentförmige Ausformung aufweist, die in einer zweiten kugelsegmentförmigen Ausformung am Lehnenträger gelagert ist. Der Mittelpunkt, um den sich die Lehne bewegen kann, liegt an der Polsteroberfläche. Seitlich und oberhalb und unterhalb des Kardanaelenkes sind Federelemente zwischen Lehne und Lehnenträger vorgesehen, z.B. elastische Polyester-Elemente, die Federkräfte sowohl senkrecht als auch parallel zur Lehnenfläche ausüben.A chair of the kind described is e.g. from EP-A 0308538 known. In this known chair, the cardanic bearing is achieved in that the backrest has a spherical segment-shaped formation, which is mounted in a second spherical segment-shaped formation on the backrest support. The center around which the backrest can move lies on the upholstery surface. Laterally and above and below the Kardanaelenkes spring elements between the backrest and backrest support are provided, e.g. Elastic polyester elements that exert spring forces both perpendicular and parallel to the backrest surface.
Dieser bekannte Stuhl bietet zwar einen hervorragenden Sitzkomfort, bedingt aber einen gewissen Aufwand bei seiner Herstellung.Although this known chair offers excellent seating comfort, but requires a certain effort in its manufacture.
Ein anderer Stuhl mit kardanisch gelagerter Lehne ist bekannt aus EP-A 0935934. Die kardanische Lagerung wird dort mittels eines kreiszylindrischen gummielastischen Elementes erreicht, an dessen zwei Stimseiten jeweils eine Stahlplatte anvulkanisiert ist, die mit der Lehne bzw. dem Lehnenträger durch Schrauben verbunden ist. Der Benutzer kann damit die Lehne gegen die Federkräfte des gummielastischen Elementes bewegen. Zusätzlich kann noch der Lehnenträger gegen eine Rückholfeder nach hinten gedrückt werden. An seiner Benutzeroberfläche ist das Polster prinzipiell steif ausgeführt und im Bereich des Gummilagers geknickt.Another gimbal-mounted chair is known from EP-A 0935934. The gimbal bearing is achieved there by means of a circular-cylindrical rubber-elastic element, on whose two ends a steel plate is vulcanized, which is connected to the back or the backrest support by screws. The user can thus move the back against the spring forces of the rubber-elastic element. In addition, the backrest support can still be pressed against a return spring to the rear. On its user interface, the upholstery is basically rigid and kinked in the area of the rubber mount.
Dieser bekannte Stuhl weist zwar den Vorteil auf, dass das Kardanlager weniger Einzelteile umfasst, und damit kostengünstiger herstellbar ist. Durch die konventionelle Gestaltung der Benutzeroberfläche des Lehnenpolsters wird aber keine optimale Stützung des Rückens des Benutzers erzielt Femer ist auch die Anlenkung des Lehnenträgers an der Stuhlsäule und die Anbindung an eine Rückholfeder sehr aufwendig und damit kostenungünstig. Schließlich ist es auch nachteilig, dass das gummielastische Lager keinen Abreißschutz bietet: wenn sich die an das gummielastische Element anvulkanisierten Platten lösen sollten, fällt die Lehne vom Lehnenträger ab.Although this known chair has the advantage that the gimbal comprises fewer items, and thus is less expensive to produce. By the conventional design of the user interface of the backrest cushion but no optimal support of the user's back is achieved Femer is also the articulation of the backrest support to the chair column and the connection to a return spring very expensive and thus costly. Finally, it is also disadvantageous that the rubber-elastic bearing offers no tear protection: if the vulcanized to the rubber-elastic element panels should solve, the backrest falls from the backrest carrier.
Es ist daher die Aufgabe der Erfindung, eine kardanisch gelagerte und über Federelemente gestützte Rückenlehne derart auszubilden, dass sie einerseits dem Rücken des Benutzers bei allen möglichen Bewegungen, sei es sagittal, transversal oder tordierend, optimale Stützung bietet, andererseits aber dennoch kostengünstig herstellbar ist. Ferner soll auch eine hohe Stabilität der Konstruktion im robusten Alltagsbetrieb gewährleistet sein. Schließlich soll die efindungsgemäße Rückenlehne auch ästhetisch, unter den Kriterien des industriellen Designs, eine optimale Lösung darstellen.It is therefore the object of the invention to form a gimbal-mounted and supported by spring elements backrest such that on the one hand the user's back in all possible movements, be it sagittal, transversal or twisting, provides optimal support, on the other hand, however, is still inexpensive to produce. Furthermore, a high stability of the construction should be ensured in the robust everyday operation. Finally, the backrest according to the invention should also be aesthetically, under the criteria of industrial design, an optimal solution.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.This object is solved by the features of
Der Kem der Erfindung ist die Idee, die Lehne aus einem Rahmen und einer darin aufgespannten Membran aufzubauen, und den Rahmen derart zu gestalten, dass er einerseits die Membran optimale Stützungskräfte für den Rücken des Benutzers entfalten lässt, andererseits aber in eleganter Weise und technisch kostengünstig und stabil die kardanische Verbindung zwischen Lehne und Lehnenträger ermöglicht.The Kem of the invention is the idea to build the back of a frame and a membrane spanned therein, and to make the frame such that it allows the membrane to develop optimal support forces for the user's back, but on the other hand in an elegant and cost-effective manner and stable the gimbal connection between backrest and backrest support allows.
Dadurch ist es möglich, die Rückenlehne samt Träger und dorsokinetisch flexiblem Gelenk als Sichtteil, also ohne besondere Verkleidung, auszubilden, was nicht nur die Zahl der Einzelteile und damit den Hersteliaufwand reduziert, sondern auch gestalterisch prägt und einen hohen Wiedererkennungswert realisiert.This makes it possible to form the backrest together with the carrier and dorsokinetisch flexible joint as a visible part, ie without special fairing, which not only reduces the number of items and thus the Hersteliaufwand, but also shapes the design and realized a high recognition value.
Auch die Zahl der konstruktiven Elemente des dorsokinetisch flexiblen Gelenkes ist auf ein Minimum reduziert, und drückt damit den Herstellaufwand. Dennoch verfügt die efindungsgemäße Rückenlehne aber über einen Abreißschutz: selbst bei einem Ablösen der anvulkanisierten Stahlplatten fällt die Lehne nicht herab, sondern bleibt am Träger befestigt.The number of constructive elements of the dorsokinetisch flexible joint is reduced to a minimum, and thus expresses the manufacturing effort. Nevertheless, the backrest according to the invention has a tear-off protection: even with a detachment of the vulcanized steel plates, the back does not fall down, but remains attached to the support.

In Fig. 1 ist ein Bürostuhl in Seitenansicht dargestellt, der eine Rückenlehne mit einem Seitenteil 1, einen Lehnenträger 2, ein dorsokinetisch flexibles Gelenk 3, ein Untergestell mit Rollen 14, eine Säule 15, eine Neigemechanik 16, und einen Sitz 17 umfasst. Der Lehnenträger 2 ist mit der Neigemechanik 16 und dem Sitz 17 derart gelenkig verbunden, dass sich beim Absenken des hinteren Teils des Sitzes 17 synchron eine Neigung des Lehnenträgers 2 ergibt. Die Einzelheiten einer solchen Mechanik mit Synchronsteuerung von Sitz und Lehne sind bekannt z.B. aus der DE-A 196 40 564. Das Seitenteil 1 der Rückenlehne weist eine längs verlaufende Nut 4 auf. Im dorsokinetisch flexiblen Gelenk 3 ist der Drehregfer 9 gezeigt.In Fig. 1, an office chair is shown in side view, comprising a backrest with a
In Fig. 2 ist zu sehen, wie die Seitenteile 1 der Rückenlehne mittels eines unteren Querstegs 6 und eines oberen Querstegs 18 einen Rahmen bilden, in dem die Membran 5 aufgespannt ist. Der Rahmen besteht vorzugsweise aus Kunststoff. Die Membran 5 besteht vorzugsweise aus einem elastischen Gewebe. Sie hat kederumfasste Seitenkanten, mittels derer sie in die Nuten 4 an den beiden Seitenteilen 1 des Rahmens eingeclipst ist.In Fig. 2 it can be seen how the
Der obere Quersteg 18 verbindet die beiden Seitenteile 1 des Rahmens an ihren oberen Enden, der untere Quersteg 6 verbindet die beiden Seitenteile 1 in Höhe der Lendenwirbel des Benutzers. Auf diese Weise kann dem RückenlehnenRahmen bei minimalem Materialaufwand eine hohe Stabilität erteilt werden, und kann insbesondere die Spannung der Membran 5 im Bereich des unteren Querstegs 6, und damit im kritischen Lendenwirbel-Bereich des Benutzers, am größten gemacht werden. Desgleichen ist das dorsokinetisch flexible Gelenk 3 im Lendenwirbelbereich angeordnet. Durch diese Gesamtkombination der für die Stützung des Rückens wesentlichen Elemente ergibt sich ein optimaler Sitzeffekt. Außerdem wirkt diese Gesamtkombination trotz ihrer Stabilität und Robustheit leicht und transparent.The upper
Zur Abrundung des hohen Sitzkomforts sind am oberen Quesrsteg 18 des Rahmens Gelenkpfannen 7 vorgesehen, in welchen neigungsverstellbar eine Nackenstütze 8 gelagert ist.To round off the high
In Fig. 3 und Fig. 4 ist das dorsokinetisch flexible Gelenk 3 in seinen Einzelheiten dargestellt.In Fig. 3 and Fig. 4, the dorsokinetisch flexible joint 3 is shown in its details.
Die Konstruktion weist einen kreiszylindrischen Gummipuffer 10 auf, der aus einem gummielastischen Werkstoff besteht, und an dessen Außenseiten Stahlplatten 11,12 anvulkanisiert sind. Zentrisch weist der Gummipuffer 10 eine Ausnehmung auf, in der ein konifizierter Stahlring 13 angeordnet ist. Dieser bildet mit den Stahlplatten 11,12 Hinterschneidungen. Der Stahlring 13 wird mittels der Schraube 20 mit dem unteren Quersteg 6 verschraubt und hält über den Hinterschnitt die Stahlplatte 11 am Rückenlehnenrahmen fest. Die Stahlplatte 12 ist mit dem Lehnenträger 2 verschraubt. Dadurch verfügt das dorsokinetische Gelenk 3 über einen Abreißschutz: Löst sich die Vulkanisierung zwischen Gummipuffer 10 und Stahlplatten 11, 12, so fällt die Lehne dennoch nicht ab, sondern bleibt mit dem Träger 2 wirkverbunden und funktionstüchtig.The construction has a circular
Schließlich ist in Fig. 3. und Fig. 4 noch der Drehregler 9 zu sehen: Dieser besteht aus Stahl und hat die Form eines zylindrischen Ringes, dessen Mantel abgeschrägt ist derart, dass die Höhe des Mantels auf der einen Seite etwa gleich dem Abstand zwischen Quersteg 6 und Lehnenträger 2 ist, und auf der gegenüberüegenden Seite kleiner als dieser Abstand. Steht dieser Drehregter 9 nun in der in Fig. 3 dargestellten Stellung, so blockiert er die Bewegungsmöglichkeit des oberen teils des Quersteges 6 und damit der Rückenlehne. In der in Fig. 4 dargestellten Stellung, in der der Drehregler 9 gegenüber der Stellung in Fig. 3 um 180° verdreht ist, kann sich jedoch der obere Teil der Rückenlehne frei bewegen.Finally, in Fig. 3. And Fig. 4 is still the
Wie das besprochene Ausführungsbeispiel überzeugend zeigt, weist die Rückenlehne nach der Efindung die aufgabengemäßen Vorteile vollumfänglich auf: sie bewirkt hervorragenden Sitzkomfort durch optimale Stützung des Rückens, ist mit gegenüber dem Stand der Technik erheblich reduziertem Aufwand herzustellen, und bietet vom industriellen Design her eine hohe Ästhetik und gestalterische Einprägbarkeit.As the discussed embodiment convincingly shows, the backrest after Efindung the task-related benefits fully: it causes excellent seating comfort through optimal support of the back, is to produce compared to the prior art, significantly reduced effort, and offers a high aesthetics of industrial design and creative embossability.
