Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Vorrichtung zur Synchronanpassung von Sitz und Rückenlehne eines Stuhles an die Körperhaltung eines Benutzers gemäß Oberbegriff des Patentanspruches 1.The invention relates to a device for synchronous adjustment of the seat and backrest of a chair to the posture of a user according to the generic term of claim 1.

Stand der TechnikState of the art

Aus DE 197 29 330 A1 ist ein Stuhl mit einer Vorrichtung zur Synchronanpassung von Sitz und Rückenlehne an die Körperhaltung eines Benutzers bekannt, bei dem ein als Pendelgelenk ausgebildetes vorderes Auflager den Sitz des Stuhles mit einem Untergestell verbindet und jeweils zwischen Rückenlehne und Untergestell und zwischen Rückenlehne und Sitz eine Drehverbindung angeordnet ist, wobei die Rückenlehne von einer nicht dargestellten Rückstelleinrichtung, deren Rückstellkräfte durch Federkräfte verwirklicht werden können, beaufschlagt ist. Die Sitzfläche ist somit pendelnd gelagert. In einer im Handel erhältlichen Ausführungsform ist die Rückstelleinrichtung eine Torsionsfeder im Rückenlehnengelenklager. Die Federkraft der Torsionsfeder ist mittels einer im Untergestell unterhalb der Sitzfläche mittig angeordneten Einrichtung verstellbar. Der Nachteil dieser Einrichtung besteht darin, daß sie auf Grund ihrer Anordnung unterhalb der Sitzfläche schwer zugänglich und somit nur schlecht bedienbar ist.DE 197 29 330 A1 describes a chair with a device for synchronous adjustment known from the seat and backrest to the posture of a user, at which a front support designed as a pendulum joint the seat of the chair connects to a base and between the backrest and base and a rotary connection is arranged between the backrest and the seat, the backrest of a return device, not shown, the Restoring forces can be realized by spring forces is applied. The seat is thus swinging. In a commercially available embodiment the reset device is a torsion spring in the backrest spherical bearing. The spring force of the torsion spring is below in the underframe The center of the seat is adjustable. The disadvantage of this facility is that because of their arrangement below the seat difficult to access and therefore difficult to use.

Ein weiterer Nachteil des bekannten Standes der Technik besteht darin, daß die Rückenlehne um einen Drehpunkt unterhalb der Sitzfläche dreht, was bei einer Drehbewegung des Sitzes und der Rückenlehne keine genaue Anpassung der Rückenlehne an die Rückenkontur des Benutzers ermöglicht, d. h. diese Lösung ist ergonomisch nicht optimal.Another disadvantage of the known prior art is that the Backrest rotates around a pivot point below the seat, which is the case with a Rotational movement of the seat and backrest does not exactly adjust the Backrest to the user's back contour allows d. H. this solution is not ergonomically optimal.

Schließlich besteht ein zusätzlicher Nachteil des bekannten Standes der Technik, bei dem die Torsionsfeder mit dem Rückenlehnenausleger verbunden ist, darin, daß die Neigung der Rückenlehne begrenzt ist, da die Torsionsfeder die gesamte Rückenlehnenneigung aufnehmen muß.Finally, there is an additional disadvantage of the known prior art, in which the torsion spring is connected to the backrest boom, in that the Backrest tilt is limited because the torsion spring covers the entire backrest tilt must record.

Darstellung der ErfindungPresentation of the invention

Die Erfindung versucht, diese Nachteile zu vermeiden. Ihr liegt die Aufgabe zugrunde, eine Vorrichtung zur Synchronanpassung von Sitz und Rückenlehne eines Stuhles an die Körperhaltung eines Benutzers zu schaffen, welche in ihrer Rückstellwirkung einfach und schnell einstellbar ist, einen großen Schwenkbereich der Rückenlehne aufweist und über einen ergonomisch günstigen Bewegungsablauf verfügt.The invention tries to avoid these disadvantages. It is based on the task a device for synchronous adjustment of the seat and backrest To create chairs to the posture of a user, which in its restoring effect is easily and quickly adjustable, a large swivel range of the backrest and has an ergonomically favorable movement sequence.

Erfindungsgemäß wird dies bei einer Vorrichtung nach dem Oberbegriff des Patentanspruches 1 dadurch erreicht, daß mindestens eine Torsionsfeder axial im vorderen und/oder hinteren Sitzschalengelenk zwischen Sitz und Rückenlehne angeordnet ist, und daß das Pendelgelenk eine drehbar gelagerte Verbindung zwischen dem Lehnenträger und dem Standsäulenaufnahmegehäuse darstellt.According to the invention, this becomes in a device according to the preamble of the claim 1 achieved in that at least one torsion spring axially in the front and / or rear seat shell joint arranged between the seat and backrest is, and that the pendulum joint is a rotatably mounted connection between represents the backrest support and the column support housing.

Die Vorteile der Erfindung bestehen darin, daß der Schwenkbereich der Rückenlehne gegenüber dem bekannten Stand der Technik erweitert ist, da die Torsionsfeder nur die Relativschwenkung zwischen Sitz und Rückenlehne aufnehmen muß und die Vorrichtung ergonomisch günstig ist, weil der Lehnenträger auf einer Kreisumlaufbahn des Pendelgelenkes schwenkt und damit eine extrem gute Anpassung der Bewegung von Sitz und Rückenlehne an die Rücken- und Beckenkontur des Benutzers erreicht wird.The advantages of the invention are that the pivoting range of the backrest Compared to the known prior art, since the torsion spring only the relative swivel between the seat and backrest must accommodate and The device is ergonomically favorable because the backrest support is in a circular orbit of the pendulum joint swivels and thus an extremely good adjustment the movement of the seat and backrest against the back and pelvic contour of the user is achieved.

Es ist zweckmäßig, wenn die Torsionsfeder axial im hinteren Sitzschalengelenk angeordnet ist und über ein Halterungs- und Spannelement mit der Einrichtung zur Verstellung der Rückstellkräfte verbunden ist, wobei diese Einrichtung im hinteren Bereich nahe der Rückenlehne angeordnet und seitlich unterhalb der Sitzfläche des Stuhles bedienbar ist. Dadurch wird eine schnelle und einfache Bedienung der Einrichtung zur Verstellung der Rückstellkräfte ermöglicht.It is expedient if the torsion spring is arranged axially in the rear seat shell joint is and via a bracket and tensioning element with the device for adjustment the restoring forces is connected, this device in the rear area arranged near the backrest and laterally below the seat of the Chair is operable. This will allow quick and easy operation of the facility allows to adjust the restoring forces.

Weg zur Ausführung der ErfindungWay of carrying out the invention

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles und der Figuren 1 und 2 näher erläutert.The invention is described below using an exemplary embodiment and the figures 1 and 2 explained in more detail.

Fig. 1 zeigt eine Seitenansicht eines Stuhles mit der erfindungsgemäßen Vorrichtung zur Synchronanpassung von Sitz und Rückenlehne an die Körperhaltung eines Benutzers, während in Fig. 2 die Vorrichtung perspektivisch als Draufsicht dargestellt ist. Zum besseren Verständnis der Erfindung sollten beide Figuren gleichzeitig herangezogen werden.Fig. 1 shows a side view of a chair with the device according to the invention for synchronous adjustment of the seat and backrest to the posture of a user, while in Fig. 2 the device in perspective as a plan view is shown. For better understanding of the invention, both figures should be used at the same time.

Der Stuhl besteht im wesentlichen aus einem Sitz 1, einer Rückenlehne 2, einer mittigen Standsäule 3, einem Lehnenträger 4 und einem Standsäulenaufnahmegehäuse 5, sowie einem vorderen Sitzschalengelenk 6, einem hinteren Sitzschalengelenk 7, einer Rückstelleinrichtung in Form einer Torsionsfeder 8, einer Einrichtung zur Verstellung der Rückstellkräfte 9 und einem Pendelgelenk 10. The chair consists essentially of a seat 1, a backrest 2, one central column 3, a backrest support 4 and a column support housing 5, and a front seat pan joint 6, a rear seat pan joint 7, a reset device in the form of a torsion spring 8, a device for adjusting the restoring forces 9 and a pendulum joint 10.

Das vordere Sitzschalengelenk 6 ist ein Drehgelenk für den Sitz 1, welches ausserdem mit dem Standsäulenaufnahmegehäuse 5 verbunden ist. Das hintere Sitzschalengelenk 7 ist mit dem Lehnenträger 4 verbunden und dient als Drehgelenk für die Rückenlehne 2. Erfindungsgemäß ist bei dieser bevorzugten Ausführungsvariante in dem hinteren Sitzschalengelenk 7 axial eine Torsionsfeder 8 angeordnet. Die Torsionsfeder 8 bewirkt eine Rückstellkraft zwischen Sitz 1 und Rückenlehne 2. Sie ist mit der Einrichtung zur Verstellung der Rückstellkräfte (Federkraftverstellung) 9 über ein keilförmig ausgebildetes Halterungs- und Spannelement 11 verbunden, wobei die Einrichtung 9 im hinteren Bereich des Lehnenträgers 4 nahe der Rückenlehne 2 angeordnet ist. Sie läßt sich seitlich einfach bedienen, indem durch Drehen des Stabes 9 mittels einer Zahnrad- Zahnstangenverbindung die Drehbewegung der Einrichtung 9 in eine Horizontalbewegung umgewandelt wird, welche dazu führt, daß das Halterungs- und Spannelement 11 seine Lage verändert und entsprechende Rückstellkräfte im Torsionsstab 8 eingestellt werden.The front seat pan joint 6 is a swivel joint for the seat 1, which also is connected to the column support housing 5. The rear Seat shell joint 7 is connected to the backrest support 4 and serves as a swivel joint for the backrest 2. According to the invention in this preferred embodiment A torsion spring 8 is arranged axially in the rear seat shell joint 7. The torsion spring 8 causes a restoring force between the seat 1 and Backrest 2. It is equipped with the device for adjusting the restoring forces (spring force adjustment) 9 via a wedge-shaped mounting and tensioning element 11 connected, the device 9 in the rear area of the backrest support 4 is arranged near the backrest 2. It can be easily moved sideways operate by turning the rod 9 by means of a rack and pinion connection the rotational movement of the device 9 is converted into a horizontal movement which leads to the mounting and tensioning element 11 changed its position and set corresponding restoring forces in the torsion bar 8 become.

Das Pendelgelenk 10 stellt ein drehbares Verbindungselement zwischen einer feststehenden Achse 12 und einer Lehnenträger-Verbindungsachse 13, welche den linken und rechten Lehnenträger 4 verbindet, dar. Es ist zwischen dem vorderen Sitzschalengelenk 6 und dem hinteren Sitzschalengelenk 7 (bzw. der Torsionsfeder 8) angeordnet und dem Lehnenträger 4 zugeordnet.The pendulum joint 10 provides a rotatable connecting element between one fixed axis 12 and a backrest connecting axis 13, which connects the left and right back support 4, it is between the front Seat shell joint 6 and the rear seat shell joint 7 (or the torsion spring 8) arranged and assigned to the backrest support 4.

Die Wirkungsweise der erfindungsgemäßen Vorrichtung ist wie folgt:

  • Fig. 1 zeigt mit durchgezogenen Linien die Stellung der eben beschriebenen Teile des Stuhles im unbelasteten Zustand, d. h. ohne Benutzer. Setzt sich nun ein Benutzer auf den Sitz 1 und lehnt sich zurück, so wird zunächst eine Drehbewegung des Sitzes am vorderen Sitzschalengelenk 6 um das Standsäulenaufnahmegehäuse 5 hervorgerufen. Da der Sitz 1 nicht nur über das vordere Sitzschalengelenk 6, sondern mittelbar auch über den Lehnenträger 4 drehbar mit dem Standsäulenaufnahmegehäuse 5 in Verbindung steht, wird das Pendelgelenk 10 aktiviert. Die Verbindungsachse 13 beschreibt eine Kreisumlaufbahn (s. gestrichelte Linie) und bewirkt wiederum eine Drehbewegung des Lehnenträgers 4 um das hintere Sitzschalengelenk 7. Die Drehung um das hintere Sitzschalengelenk 7 beaufschlagt die Torsionsfeder 8. Mit dieser Lösung wird vorteilhaft erreicht, daß die Torsionsfeder 8 im Gegensatz zum bekannten Stand der Technik nur die Relativdrehung zwischen Sitz 1 und Rückenlehne 2 mitmachen muß und daher der realisierbare Schwenkbereich der Rückenlehne wesentlich größer ist, als wenn die Torsionsfeder die gesamte Rückenlehnendrehung mitmachen müßte.
    • The operation of the device according to the invention is as follows:
  • Fig. 1 shows with solid lines the position of the parts of the chair just described in the unloaded state, ie without users. If a user now sits on the seat 1 and leans back, a rotational movement of the seat on the front seat shell joint 6 about the column support housing 5 is first caused. Since the seat 1 is rotatably connected to the column support housing 5 not only via the front seat pan joint 6, but also indirectly via the backrest support 4, the pendulum joint 10 is activated. The connecting axis 13 describes a circular orbit (see dashed line) and in turn causes the backrest support 4 to rotate about the rear seat pan joint 7. The rotation about the rear seat pan joint 7 acts on the torsion spring 8. This solution advantageously achieves that the torsion spring 8 in Contrary to the known prior art, only the relative rotation between seat 1 and backrest 2 has to take part and therefore the realizable pivoting range of the backrest is considerably larger than if the torsion spring had to go along with the entire backrest rotation.

    • Da der Lehnenträger 4 auf einer Kreisumlaufbahn des Pendelgelenkes schwenkt und nicht nur über einen einfachen Drehpunkt gedreht wird, erfolgt zudem ein wesentlich besserer Rückenlehnenbewegungsablaut der beim Zurückneigen des Benutzers eine optimale Anpassung an die Rückenkontur ermöglicht, da die Lehne 2 den Kontakt im Beckenbereich nahezu konstant beibehält. Dies ist ergonomisch günstig. Die Rückstellkräfte zum Rückstellen der Lehne 2 in die Ausgangsposition können mittels der o. b. Einrichtung 9 schnell und bedienungsfreundlich eingestellt werden.Since the backrest support 4 pivots on a circular orbit of the pendulum joint is not only rotated via a simple pivot point, there is also an essential one better backrest movement sound that when the user leans back allows optimal adaptation to the back contour, since the backrest 2 the contact maintained almost constant in the pool area. This is ergonomically favorable. The Restoring forces for resetting the backrest 2 into the starting position can be done by means of the o. b. Setup 9 can be set quickly and easy to use.

    Selbstverständlich ist die Erfindung nicht auf das beschriebene Ausführungsbeispiel beschränkt. So kann z. B. die Torsionsfeder 8 im hinteren Sitzschalengelenk 7 durch eine zweite Torsionsfeder 8 im vorderen Sitzschalengelenk 6 ergänzt werden. Eine weitere Möglichkeit besteht darin, nur im vorderen Sitzschalengelenk 6 eine Torsionsfeder 8 einzubringen. Of course, the invention is not based on the described embodiment limited. So z. B. the torsion spring 8 in the rear seat pan joint 7 by a second torsion spring 8 can be added to the front seat pan joint 6. A Another possibility is a torsion spring only in the front seat pan joint 6 8 to bring.
