Description

Die Erfindung betrifft eine Sitzteillagerung für ein allseitig elastisch neigbares Sitzteil einer Sitzvorrichtung, insbesondere eine Gelenkkombination für einen Bürostuhl.The invention relates to a seat storage for an all-round elastically tiltable seat part of a seat device, in particular a joint combination for an office chair.

Sitzvorrichtungen mit einfacher Verschwenkbarkeit des Sitzteils gegenüber einem Fußaufbau sind allgemein bekannt. Eine einfache Verschwenkbarkeit bedeutet, daß das Sitzteil in einer Schwenkrichtung entsprechend der Sitzrichtung nach vorn oder hinten verkippbar ist. Ist das verschwenkbare Sitzteil mit einer Rückenlehne verbunden, so wird das Verschwenken des Sitzteils mit dem der Rückenlehne gekoppelt. Bei einer starren Kopplung von Sitzteil und Rückenlehne würde sich die letztere immer um den gleichen Winkel neigen wie das Sitzteil. Dies ist jedoch aus Sicht des Sitzkomforts in der Regel nicht gewünscht. Zur Abhilfe dieses Problems wurde in der Vergangenheit eine Synchronmechanik entwickelt, die im folgenden unter Bezug auf die Fign. 3 und 4 (Stand der Technik) erläutert wird.Seat devices with easy pivoting of the seat part to a foot structure are well known. A easy pivoting means that the seat part in a Pivoting direction according to the seating direction forward or can be tilted behind. Is the pivoting seat part with connected to a backrest, so is the pivoting of the Seat part coupled with the backrest. At a rigid Coupling of seat and backrest would be the latter always tilt at the same angle as the seat part. This is However, from the perspective of seating comfort usually not desired. To remedy this problem has been in the past a synchronous mechanism developed in the following below Reference to Figs. 3 and 4 (prior art) explained becomes.

Fig. 3 zeigt in schematischer Seitenansicht links eine normale Sitzposition mit horizontaler Sitzfläche und im wesentlichen vertikaler Rückenlehne. Die Rückenlehne ist gegenüber der Vertikalen leicht geneigt, wobei es der sitzenden Person jedoch kein Problem ist, sich geringfügig nach vorn zu beugen. Im rechten Teil von Fig. 3 ist die verschwenkte Sitzposition dargestellt. Die Sitzvorrichtung ist beispielsweise dazu eingerichtet, daß die Rückenlehne von einem Winkel 0 bis zu einem Winkel α verschwenkbar ist. Zur Erzielung des Sitzkomforts soll die Sitzfläche bei maximaler Verschwenkung der Rückenlehne weniger als um den Winkel α verschwenkt sein. Hierzu ist die Synchronmechanik vorgesehen, die in Fig. 4A in schematischer Seitenansicht und in Fig. 4B in schematischer Draufsicht gezeigt ist. Die Synchronmechanik ist dazu ausgebildet, daß bei einem Schwenkvorgang der Schwenkwinkel der Sitzfläche zum Schwenkwinkel der Rückenlehne entsprechend einem Winkelverhältnis 1 : x in Beziehung steht, wobei der Parameter x für Bürostühle in der Regel ungefähr 2 bis 3 beträgt.Fig. 3 shows a schematic side view on the left a normal Sitting position with horizontal seat and essentially vertical backrest. The backrest is opposite the vertical slightly inclined, but it is the seated person no problem is to lean slightly forward. in the right part of Fig. 3, the pivoted seat position is shown. The seat device is configured, for example, to that the backrest from an angle 0 to a Angle α is pivotable. To achieve the seating comfort the seat at maximum pivoting of the backrest less be pivoted by the angle α. For this is the Synchronous mechanism provided in Fig. 4A in schematic Side view and shown in Fig. 4B in a schematic plan view is. The synchronous mechanism is designed so that at a pivoting operation of the pivot angle of the seat for Swing angle of the backrest according to an angle ratio 1: x is related, where the parameter x for Office chairs is usually about 2 to 3.

Die Synchronmechanik 10' (s. Fig. 4A, B), die am oberen Ende einer Trägersäule 41' angebracht ist, umfaßt im wesentlichen ein Gehäuse 11' für einen Hebelmechanismus, an dem ein erster Schwenkarm 12a' und ein zweiter Schwenkarm 12b', die zur Einstellung des gewünschten Winkelverhältnisses zusammenwirken, angelenkt sind. Der erste Schwenkarm 12a' bildet einen gabelförmigen Ausleger und ist mit der Rückenlehne (nicht dargestellt) starr verbunden. Der zweite Schwenkarm 12b' ist am oberen Ende des Gehäuses 11' verschwenkbar angelenkt und dient als Träger des Sitzteiles (nicht dargestellt). Im Gehäuse 11' ist der Hebelmechanismus zur Einstellung des Winkelverhältnisses enthalten. Zur Einstellung der Schwenkparameter bzw. des Winkelverhältnisses sind am Gehäuse 11' ferner Betätigungstasten 13' zur Höhenverstellung bzw. zur Blockierung in bestimmten Winkelpositionen und ein Handrad 14' zur Federkrafteinstellung in Abhängigkeit vom Gewicht der sitzenden Person vorgesehen.The synchronizing mechanism 10 '(see Fig. 4A, B), which at the upper end a support column 41 'is mounted substantially comprises a housing 11 'for a lever mechanism to which a first Swivel arm 12a 'and a second pivot arm 12b', for adjustment cooperate the desired angular ratio, are articulated. The first pivot arm 12a 'forms a fork-shaped Cantilever and is connected to the backrest (not shown) rigidly connected. The second pivot arm 12b 'is on hinged upper end of the housing 11 'and serves as a carrier of the seat part (not shown). In the housing 11 ' is the lever mechanism for setting the angle ratio contain. For setting the swivel parameters or the Angular ratio are on the housing 11 'further operation buttons 13 'for height adjustment or blocking in certain Angular positions and a handwheel 14 'for adjusting the spring force depending on the weight of the person sitting intended.

Die herkömmliche Synchronmechanik besitzt den Nachteil eines eingeschränkten Einsatzbereiches bei Sitzvorrichtungen mit einfacher Verschwenkbarkeit.The conventional synchronous mechanism has the disadvantage of limited use in seating devices with easy pivoting.

Bei Sitzmöbeln ist es ferner ergonomisch sinnvoll, ein Sitzteil vorzusehen, das relativ zum Fußaufbau nach allen Seiten neigbar gelagert ist, so daß ein aktiv-dynamisches Sitzen gewährleistet wird. Für ein derartiges aktiv-dynamisches Sitzmöbel ist aus dem Gebrauchsmuster DE 295 16 794.7 ein Sitzgelenk bekannt, das schematisch in Fig. 5 (Stand der Technik) gezeigt ist. Das Sitzgelenk 20' stellt die Verbindung zwischen einer Trägersäule (nicht dargestellt) und einem Sitzteil (nicht dargestellt) z.B. eines Bürostuhles über ein Auflagerteil 21' und eine allseits neigbare Platte 22' her. Auf der oberen Seite des Auflagerteils 21' befindet sich eine nach oben gekrümmte Auflagefläche 23', auf der mittig mittels einer Schraube 24' oder einer entsprechenden Verbindung die Platte 22' angebracht ist. Die Schraube 24' besteht aus einem elastischen Material und erlaubt ein allseitiges Verschwenken der Platte 22' auf der Auflagefläche 23'. Zur Begrenzung der Schwenkbewegung der Platte 22' ist ein Begrenzer 25' in Form einer ringförmig allseits auskragenden Platte vorgesehen, der aus einem ringförmigen Träger 26' und einer elastischen Auflage 27' (z.B. aus Gummi) besteht. Die Einstellhöhe des Trägers 25' kann mit einem Stellring 28' eingestellt werden, der auf einem Außengewinde 29' des Auflagerteils 21' verdrehbar ist. Weitere Merkmale und Modifikationen des Sitzgelenks 20' sind im obengenannten Gebrauchsmuster beschrieben, auf dessen Inhalt hiermit ausdrücklich Bezug genommen wird. Der Einsatz allseitig neigbarer Sitzteile auf der Grundlage eines Gelenks gemäß Fig. 5 war bisher auf aktiv-dynamische Sitzvorrichtungen beschränkt, die zwar ein gesundes und ergonomisch sinnvolles Sitzen ermöglichen, für bestimmte Sitzsituationen, insbesondere im Bürobereich, jedoch gegebenenfalls nicht den nötigen Komfort bieten.For seating, it is also ergonomically useful, a seat part provide, relative to the foot structure in all directions tiltable, so that an active-dynamic seats guaranteed becomes. For such active-dynamic seating is from the utility model DE 295 16 794.7 a seat hinge 5, which is shown schematically in FIG. 5 (prior art) is. The seat hinge 20 'provides the connection between a Support column (not shown) and a seat part (not shown) e.g. an office chair via a support part 21 'and a universally tiltable plate 22 'ago. On the upper side of the support part 21 'is an upwardly curved Support surface 23 ', on the center by means of a screw 24' or a corresponding connection the plate 22 'attached is. The screw 24 'is made of an elastic material and allows an all-round pivoting of the plate 22 'on the support surface 23 '. To limit the pivoting movement of Plate 22 'is a limiter 25' in the form of an annular all-round projecting plate provided, consisting of an annular Carrier 26 'and a resilient support 27' (e.g. Rubber). The setting height of the carrier 25 'can with a collar 28 'are set, which on an external thread 29 'of the support part 21' is rotatable. Other features and modifications of the seat hinge 20 'are in the above Utility model described in the content of which hereby express reference is made. The use tilted on all sides Seat parts based on a joint according to FIG. 5 was previously limited to active-dynamic seating devices, which allow a healthy and ergonomic sense of sitting, for certain seating situations, in particular in the office sector, but may not provide the necessary comfort.

Es ist die Aufgabe der vorliegenden Erfindung, eine verbesserte Sitzteillagerung für eine Sitzvorrichtung anzugeben, mit der die Beschränkungen herkömmlicher Sitzteillagerungen oder Gelenke überwunden werden und die einen relativ einfachen Aufbau besitzt.It is the object of the present invention to provide an improved To specify seat storage for a seat device, with the limitations of conventional seating arrangements or Joints are overcome and provide a relatively simple structure has.

Diese Aufgabe wird durch eine Sitzteillagerung mit den Merkmalen gemäß Schutzanspruch 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen. This task is performed by a seat storage with the features solved according to protection claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.

Die Bewegungen von Sitz und Lehne sind nicht miteinander gekoppelt, sondern können völlig unabhängig voneinander erfolgen. From WO 98/48668 an office chair is known in which the Seat is mounted on the base frame so that it is after Can be tilted front and back, while the back so stored is that they are panned right and left can. The movements of the seat and backrest are not identical coupled, but can be done completely independently.

Die Grundidee der Erfindung besteht darin, eine neuartige Sitztteillagerung anzugeben, die aus zwei Grundkomponenten besteht. Diese Grundkomponenten umfassen erstens eine Synchronmechanik, deren Funktion an sich von der obengenannten Technik bekannt ist und die im Rahmen der vorliegenden Erfindung konstruktiv an den Zusammenbau mit der zweiten Grundkomponente angepaßt ist. Die zweite Grundkomponente umfaßt im wesentlichen ein allseitig elastisch neigbares Gelenk, wie es ebenfalls für sich allein von den aktiv-dynamischen Sitzvorrichtungen bekannt ist. Erfindungsgemäß ist am zweiten Schwenkarm einer Synchronmechanik das Sitzteil nicht direkt starr befestigt, sondern über ein Gelenk angebracht, das eine allseitige Neigbarkeit des Sitzteils gegenüber der Synchronmechanik gewährleistet.The basic idea of the invention is a novel Specify seat storage, which consists of two basic components. These basic components include firstly a synchronous mechanism, their function in itself of the above technique is known and the constructive in the context of the present invention to the assembly with the second basic component is adapted.

Das untere Ende des Gehäuses 11 ist an der Trägersäule 41 der Sitzvorrichtung angebracht. Das freie Ende des ersten Schwenkarms 12a bildet einen Lehnenansatz, über den die Rückenlehne (nicht dargestellt) mit dem ersten Schwenkarm 11 fest verbunden ist. Die Sitzfläche 31 ist auf der Oberseite der Platte 22 des Gelenkteils 20 angebracht und umfaßt ein in an sich bekannter Weise gestaltetes und gepolstertes Bauteil.The seat storage according to the invention is schematically, partially as a sectional view, illustrated in Fig. 1. The seat storage comprises the Synchronmechhanik 10 with the housing 11, the first pivot arm 12a and the second pivot arm 12b, and the hinge part 20 with the support part 21, the plate 22, the Limiter 25 and the collar 28. The lower end of the housing 11 is attached to the support column 41 of the seat device. The free end of the first pivot arm 12a forms a Backrest approach over which the backrest (not shown) with the first pivot arm 11 is firmly connected. The seat 31 is mounted on top of the plate 22 of the hinge part 20 and comprises a designed in a conventional manner and padded component.

Die Synchronmechanik 10 ist vorzugsweise entsprechend der Synchronmechhanik 10' gemäß Fig. 4 aufgebaut. Je nach Einstellung der Schwenkparameter und Winkelverhältnisse an den Betätigungstasten 13 und am Handrad 14 neigt sich der zweite Schwenkarm 12b, an dem das Auflagerteil 21 des Gelenkteils 20 angebracht ist, weniger stark als der erste Schwenkarm 12a. Beim Neigen des zweiten Schwenkarms 12b verkippt entsprechend das Auflagerteil 21. Je nach den Bedürfnissen der sitzenden Person kann diese die Kippbewegung ganz oder teilweise durch Neigung der Platte 22 gegenüber dem Auflagerteil 21 aufgrund des Eigengewichts der Person oder durch zusätzlichen Kraftaufwand kompensieren und damit die wunschgemäße Sitzposition einnehmen.The synchronizing mechanism 10 is preferably according to the Synchronmechhanik 10 'constructed as shown in FIG. 4. Depending on the setting the swing parameters and angle ratios on the operation buttons 13 and the hand wheel 14, the second tilts Swivel arm 12b, on which the support part 21 of the joint part 20th is mounted, less strong than the first pivot arm 12a. When tilting the second pivot arm 12b tilted accordingly the support part 21. Depending on the needs of the sedentary Person can do this the tilting motion in whole or in part Inclination of the plate 22 relative to the support member 21 due the weight of the person or by additional effort compensate and thus take the desired seating position.

Das Gelenkteil 20 ist vorzugsweise entsprechend dem herkömmlichen, allseitig neigbaren Gelenk gemäß Fig. 5 aufgebaut. Mit dem Stellring 28 wird die Position des Begrenzers 25 eingestellt, der wiederum entsprechend aus einem ringförmigen Träger 26 und einer Auflage aus elastischem Material (z.B. Gummi) 27 besteht. Die Elastizität der Auflage 27 dient vor allem einem weichen Aufsetzen der Platte 22 auf dem Begrenzer 25. Es kann daher alternativ auch vorgesehen sein, daß der Begrenzer 25 vollständig aus einem starren Material besteht, während die Platte 22 elastische Eigenschaften besitzt. Die Platte 22 ist mittig mit einem elastischen Verbindungselement auf der sich nach oben wölbenden Auflagefläche 23 befestigt.The joint part 20 is preferably according to the conventional, constructed on all sides tiltable joint according to FIG. With the adjusting ring 28, the position of the limiter 25 is set, in turn corresponding to an annular support 26 and a pad of elastic material (e.g., rubber) 27 exists.

Die Sitzvorrichtung umfaßt den Sitzaufbau 30 und den Fußaufbau 40, die über die (verdeckte) Sitzteillagerung mit der Synchronmechanik 10 und dem Gelenkteil 20 (s. Fig. 1) verbunden sind. Der Sitzaufbau 30 umfaßt das Sitzteil oder die Sitzfläche 31 und die Lehne 32. Der Fußaufbau 40 umfaßt die Trägersäule 41, die beispielsweise gasdruck-gefedert ist, und ein Fußkreuz 42 mit Laufrädern 43. Das Sitzteil 31 ist entsprechend den Pfeilrichtungen in Fig. 2A durch die Neigbarkeit des Gelenkteils 20 gegenüber der Trägersäule 41 verschwenkbar, wobei bei dieser Schwenkbewegung die Position der Lehne 32 unverändert bleibt (s. Fig. 2B). Erfolgt das Schwenken jedoch um eine Achse, die senkrecht zur Sitzrichtung ausgerichtet ist, so wird die Synchronmechanik am Schwenkvorgang beteiligt, so daß sich die Lehne 32 mit dem Sitzteil 31 verschwenkt (s. Fign. 2C, D).The Fign. 2A-D show different pivot situations on one Seating device according to the invention, e.g. in the form of an office chair. The seat device comprises the seat assembly 30 and the Foot assembly 40, which over the (hidden) Sitzteillagerung with the synchronizing mechanism 10 and the joint part 20 (see Fig. 1) are. The seat assembly 30 includes the seat portion or the Seat 31 and the backrest 32. The foot assembly 40 includes the Carrier column 41, which is for example gas pressure-spring-loaded, and a foot 42 with wheels 43. The seat portion 31 is corresponding the arrow directions in Fig. 2A by the inclinability of the joint part 20 with respect to the support column 41 pivotable, wherein in this pivoting movement, the position of the backrest 32 unchanged remains (see Fig. 2B). However, if the pan is over an axis that is oriented perpendicular to the seating direction, so the synchronous mechanism is involved in the panning process, so the backrest 32 pivots with the seat part 31 (see FIG. FIGS. 2C, D).

Die Erfindung ist nicht auf die Sitzteillagerung für Bürostühle beschränkt, sondern auch bei anderen Sitzvorrichtungen anwendbar, die für die Aufnahme einzelner oder mehrerer Personen (Systembestuhlung) ausgelegt sind.The invention is not on the seat storage for office chairs limited, but also applicable to other seating devices, the for the admission of single or several persons (System seating) are designed.

Ein besonderer Vorteil der Erfindung besteht darin, daß mit dem Stellring 28 des Gelenkteils 20 (s. Fig. 1) der Begrenzer 25 in eine derart hohe Position gefahren werden kann, daß eine Neigung der Platte 22 gegenüber dem Auflagerteil 21 ausgeschlossen wird. In dieser Position des Stellringes 28 besitzt eine mit der erfindungsgemäßen Sitzteillagerung ausgestattete Sitzvorrichtung die Merkmale eines herkömmlichen, einfach verschwenkbaren Stuhls. Damit können die Sitzeigenschaften einfach an die jeweiligen Anforderungen angepaßt werden. Die Einstellung der Position des Begrenzers 25 mit dem Stellring 28 kann auch durch einen anderen geeigneten, am Auflagerteil 21 höhenverstellbaren Mechanismus (z.B. verstellbare Manschette oder seitlich auskragende Zapfen) implementiert werden.A particular advantage of the invention is that with the adjusting ring 28 of the joint part 20 (see Fig. 1) of the limiter 25 can be moved in such a high position that a Inclination of the plate 22 with respect to the support part 21 excluded becomes. In this position, the adjusting ring 28 has equipped with the seat storage according to the invention Seating device the characteristics of a conventional, simple swiveling chair. This can be the site properties easily adapted to the respective requirements. The Adjusting the position of the limiter 25 with the adjusting ring 28 can also by another suitable, on the support part 21 height-adjustable mechanism (e.g., adjustable cuff or laterally cantilevered pins).

Der Begrenzer 25 kann auch durch einen anderen Feststellmechanismus ersetzt werden, der insbesondere zur Fixierung der Sitzfläche eingerichtet ist. Es kann beispielsweise eine Lamellenklemmung oder ein Keilfeststeller vorgesehen sein.The limiter 25 can also by another locking mechanism be replaced, in particular for fixing the Seat is set up. It can, for example, a lamellar clamp or a wedge lock may be provided.
