Description

Die Erfindung betrifft ein Sitzmöbel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a piece of seating furniture according to the preamble of patent claim 1.

Ein Sitzmöbel der eingangs genannten Art ist beispielsweise aus dem Patentdokument WO 1993/025121 A1 bekannt. Dieses als Stuhl ausgebildete Sitzmöbel besteht aus einer Rückenlehne, die zwei Rahmenteile aufweist, zwischen denen zur Ausbildung einer Rückenanlagefläche für einen Benutzer ein Textilmaterial gespannt angeordnet ist. Das Textilmaterial besteht dabei bei dieser Lösung vorzugsweise (siehe Seite 26, letzter Absatz) aus einem thermoplastischen Polyester-Elastomer mit der Markenbezeichnung HYTREL®. Weitere Sitzmöbel sind aus der DE20216302U1 und der EP2319967A1 bekannt.A piece of seating furniture of the type mentioned is, for example, from the patent document WO 1993/025121 A1 known. This seating furniture designed as a chair consists of a backrest, which has two frame parts, between which a textile material is stretched to form a back contact surface for a user. In this solution, the textile material preferably consists (see page 26, last paragraph) of a thermoplastic polyester elastomer with the brand name HYTREL ® . More seating is from the DE20216302U1 and the EP2319967A1 known.

Der vorstehend und nachfolgend verwendete Begriff "Rahmenteil" kann dabei auch die Bedeutung von "Rahmenabschnitt" haben, und zwar insbesondere dann, wenn die beiden Rahmenteile über entsprechende, horizontal verlaufende Querträger miteinander verbunden ausgebildet sind und die Rahmenteile und die Querträger somit letztlich zusammen einen Gesamtrahmen für das Textilmaterial bilden.The term "frame part" used above and below can also have the meaning of "frame section", in particular when the two frame parts are connected to one another via corresponding, horizontally running crossbeams and the frame parts and the crossbeams thus ultimately together form an overall frame form for the textile material.

Der vorstehend und nachfolgend verwendete Begriff "Textilmaterial" umfasst Gestricke (siehe https://de.wikipedia.org/w/index.php?title=Stricken&oldid=192740804) und Gewebe (siehe https://de.wikipedia.org/w/index.php?title=Gewebe_(Textil)&oldid= 189054729).The term "textile material" used above and below includes knitted fabrics (see https://de.wikipedia.org/w/index.php?title=Stricken&oldid=192740804) and woven fabrics (see https://de.wikipedia.org/w /index.php?title=Fabric_(Textile)&oldid= 189054729).

Der Erfindung liegt die Aufgabe zugrunde, ein Sitzmöbel der eingangs genannten Art zu verbessern. Insbesondere soll die Ergonomie und auch die Bequemlichkeit eines solchen Sitzmöbels weiter verbessert werden.The object of the invention is to improve a piece of seating furniture of the type mentioned at the outset. In particular, the ergonomics and also the comfort of such a piece of seating furniture should be further improved.

Diese Aufgabe ist mit einem Sitzmöbel der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a piece of seating furniture of the type mentioned by the features listed in the characterizing part of patent claim 1.

Es ist vorgesehen, dass mindestens ein zwischen den beiden Rahmenteilen erstreckter Abschnitt des Textilmaterials in horizontaler Richtung weniger elastisch als in vertikaler Richtung ausgebildet ist. Die genannten Richtungsangaben "horizontal" und "vertikal" gelten dabei im Rahmen dieses Dokuments stets bei bestimmungsgemäßem Gebrauch des Sitzmöbels, also wenn dieses zum Sitzen verwendet werden kann.Provision is made for at least one section of the textile material extending between the two frame parts to be less elastic in the horizontal direction than in the vertical direction. The stated directions "horizontal" and "vertical" always apply in the context of this document when the seating furniture is used as intended, i.e. when it can be used for sitting.

Mit anderen Worten weist die Rückenanlagefläche mindestens einen in horizontaler Richtung schlechter dehnbaren bzw. unelastischeren Abschnitt auf, einen Bereich also, der einem Benutzer beim Anlehnen mehr Widerstand entgegensetzt als ein anderer Abschnitt dieser Rückenlehne, bei dem die Elastizität in horizontaler und vertikaler Richtung gleich ist. Dieser Bereich bzw. Abschnitt ist dabei zur Ausbildung einer Lordosestütze für den Benutzer vorzugsweise in einem unteren Bereich der Rückenanlagefläche angeordnet.In other words, the back contact surface has at least one section that is less stretchable or less elastic in the horizontal direction, i.e. an area that offers more resistance to a user leaning against it than another section of this backrest in which the elasticity in the horizontal and vertical directions is the same. This area or section is preferably arranged in a lower area of the back contact surface to form a lumbar support for the user.

Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments emerge from the dependent patent claims.

Der Vollständigkeit halber wird auf die folgenden, weiter abliegenden Dokumente hingewiesen:
Aus dem Dokument DE 10 2014 110 611 A1 ist ein textiles Flächengebilde bekannt, dass aus einem flexiblen Substrat und darüber hinaus aus einer Vielzahl von plättchenförmigen Elementen besteht. Bei dieser Lösung ist also nicht - wie bei der erfindungsgemäßen Lösung - das Textilmaterial selbst (nämlich das flexible Substrat) für die besonderen Eigenschaften der Rückenanlagefläche verantwortlich, sondern es sind die plättchenförmigen Elemente, die die Flexibilität des Substrats beeinflussen. Bei der besagten Lösung ist also, nochmals in anderen Worten ausgedrückt, das Textilmaterial bzw. das Substrat in horizontaler Richtung genauso elastisch wie in vertikaler Richtung ausgebildet.For the sake of completeness, reference is made to the following documents that are not available:
From the document DE 10 2014 110 611 A1 a textile fabric is known that consists of a flexible substrate and, moreover, a large number of platelet-shaped elements. In this solution, it is not the textile material itself (namely the flexible substrate) that is responsible for the special properties of the back contact surface, as is the case with the solution according to the invention, but it is the platelet-shaped elements that influence the flexibility of the substrate. In the said solution, to put it another way, the textile material or the substrate is just as elastic in the horizontal direction as it is in the vertical direction.

Aus dem Dokument DE 20 2018 105 535 U1 ist schließlich eine aus zwei Schichten bestehende Rückenlehne bekannt, wobei mindestens eine Schicht aus einem harten bzw. steifen Material gebildet ist, und mithin nicht aus einem Textilmaterial bestehen kann.From the document DE 20 2018 105 535 U1 Finally, a backrest consisting of two layers is known, whereby at least one layer is formed from a hard or stiff material and therefore cannot consist of a textile material.

Das erfindungsgemäße Sitzmöbel einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The seating furniture according to the invention, including its advantageous developments according to the dependent patent claims, is explained in more detail below with reference to the graphic representation of a preferred exemplary embodiment.

Es zeigt

Figur 1
perspektivisch und schematisch das erfindungsgemäße, als Stuhl ausgebildete Sitzmöbel.
It shows
figure 1
Perspective and schematic of the seating furniture according to the invention, designed as a chair.

Das in der einzigen Figur dargestellte Sitzmöbel, hier als Stuhl ausgebildet, besteht in bekannter Weise neben einer gegen den Boden abgestützten Sitzfläche aus einer Rückenlehne 1, die zwei Rahmenteile 1.1, 1.2 aufweist, zwischen denen zur Ausbildung einer Rückenanlagefläche für einen Benutzer ein Textilmaterial 1.3 gespannt angeordnet ist. Die beiden Rahmenteile 1.1, 1.2 sind dabei, wie dargestellt, vorzugsweise vertikal verlaufend orientiert. Ferner ist bevorzugt vorgesehen, dass das Textilmaterial 1.3 wahlweise aus Polyester besteht und/oder als Gestrick oder Gewebe (mit horizontal und vertikal verlaufenden Fäden) ausgebildet ist.The piece of seating furniture shown in the single figure, designed here as a chair, consists in a known manner, in addition to a seat supported against the floor, of a backrest 1, which has two frame parts 1.1, 1.2, between which a textile material 1.3 is stretched to form a back contact surface for a user is arranged. The two frame parts 1.1, 1.2 are, as shown, preferably oriented vertically. Furthermore, it is preferably provided that the textile material 1.3 optionally consists of polyester and/or is designed as a knitted fabric or woven fabric (with horizontally and vertically running threads).

Wesentlich für das erfindungsgemäße Sitzmöbel ist nun, dass mindestens ein zwischen den beiden Rahmenteilen 1.1, 1.2 erstreckter Abschnitt 1.3.1 des Textilmaterials 1.3 in horizontaler Richtung weniger elastisch als in vertikaler Richtung ausgebildet ist.What is essential for the chair according to the invention is that at least one section 1.3.1 of the textile material 1.3 extending between the two frame parts 1.1, 1.2 is less elastic in the horizontal direction than in the vertical direction.

Dabei ist weiterhin (sofern sich der Abschnitt 1.3.1 nicht, worauf nachfolgend noch genauer eingegangen wird, über die gesamte Höhe der Rückenanlagefläche erstreckt) zur Ausbildung einer Lordosestütze für den Benutzer besonders bevorzugt vorgesehen, dass der Abschnitt 1.3.1 in einem unteren Bereich der Rückenanlagefläche angeordnet ist. Hierfür ist dabei ferner bevorzugt vorgesehen, dass der Abschnitt 1.3.1 eine vertikale Erstreckung aufweist, die geringer als eine maximale Vertikalerstreckung der Rückenanlagefläche ist.It is also (if section 1.3.1 does not extend over the entire height of the back contact surface, which will be discussed in more detail below) to form a lumbar support for the user, particularly preferably provided that section 1.3.1 in a lower area of the Back contact surface is arranged. For this purpose, it is further preferably provided that the section 1.3.1 has a vertical extent that is less than a maximum vertical extent of the back contact surface.

Zur Beeinflussung der Elastizität des Textilmaterials 1.3 ist weiterhin bevorzugt vorgesehen, dass dieses im Abschnitt 1.3.1 sogenannte, vorzugsweise horizontal verlaufende Filamentfäden enthält. Genauer betrachtet ist dabei besonders bevorzugt vorgesehen, dass die Filamentfäden weniger dehnbar als das übrige Textilmaterial 1.3 bzw. unelastischer ausgebildet sind. Ferner ist besonders bevorzugt vorgesehen, dass die Filamentfäden zwar auch aus Polyester, aber einem anderen Polyester als das übrige Textilmaterial 1.3 gebildet sind.In order to influence the elasticity of the textile material 1.3, provision is also preferably made for it to contain so-called, preferably horizontally running filament threads in section 1.3.1. More precisely, it is particularly preferred that that the filament threads are designed to be less stretchable than the rest of the textile material 1.3 or less elastic. Furthermore, it is particularly preferably provided that the filament threads are also made of polyester, but are made of a different polyester than the rest of the textile material 1.3.

Insbesondere für den oben bereits angesprochenen Fall, dass sich der Abschnitt 1.3.1 jedenfalls über einen größeren Teil der Höhe der Rückenanlagefläche oder (weil besonders einfach herstellbar) auch über die gesamte Höhe der Rückenanlagefläche erstreckt, ist weiterhin erfindungsgemäß an der Rückenlehne 1 ein mit dem Textilmaterial 1.3 zusammenwirkender (in Figur 1 sehr vereinfacht dargestellter), zur Ausbildung einer Lordosestütze im unteren Bereich der Rückenanlagefläche angeordneter Verstellmechanismus 2 vorgesehen. Genauer betrachtet, ist dabei ferner vorgesehen, dass der Verstellmechanismus 2 zur Aufbringung einer zusätzlichen Spannung auf das Textilmaterial ausgebildet ist, d. h. mit dem Verstellmechanismus 2 kann die aufgrund der Einspannung zwischen den beiden Rahmenteilen 1.1, 1.2 bereits bestehende Spannung im Textilmaterial noch weiter erhöht werden, wodurch dieses an dieser Stelle noch unelastischer wird und auf diese Weise die Lordosestütze bildet.In particular for the case already mentioned above, in which section 1.3.1 extends over a larger part of the height of the back contact surface or (because it is particularly easy to produce) also over the entire height of the back contact surface, according to the invention, a backrest 1 is equipped with a Textile material 1.3 interacting (shown in very simplified form in FIG. 1) is provided to form a lumbar support in the lower region of the back contact surface. Viewed more closely, it is also provided that the adjustment mechanism 2 is designed to apply additional tension to the textile material, i. H. With the adjustment mechanism 2, the tension in the textile material that already exists due to the clamping between the two frame parts 1.1, 1.2 can be increased even further, making it even less elastic at this point and thus forming the lumbar support.

Wie aus Figur 1 ersichtlich, ist dazu außerdem besonders bevorzugt vorgesehen, dass der Verstellmechanismus 2 ein verstell- und fixierbares Druckflächenelement 2.1 aufweist. Genauer betrachtet, ist dabei bevorzugt an jedem Rahmenteil 1.1, 1.2 ein Druckflächenelement 2.1 angeordnet. Die Druckflächenelemente 2.1 sind in diesem Fall vorzugs- und wahlweise unabhängig voneinander einstellbar und/oder unverbunden (nicht direkt miteinander verbunden) ausgebildet. Schließlich ist vorzugs- und wahlweise das Druckflächenelement 2.1 schwenk-, aber fixierbar an der Rückenlehne 1 gelagert und/oder zur Ausbildung einer rückenfreundlichen Wölbung textilmaterialseitig konvex gewölbt ausgebildet.How out figure 1 As can be seen, it is also particularly preferred for the adjustment mechanism 2 to have an adjustable and fixable pressure surface element 2.1. Viewed more closely, a pressure surface element 2.1 is preferably arranged on each frame part 1.1, 1.2. In this case, the pressure surface elements 2.1 are preferably and optionally adjustable independently of one another and/or are designed to be unconnected (not directly connected to one another). Finally, preferably and optionally the pressure surface element 2.1 is pivotably but fixably mounted on the backrest 1 and/or convexly curved to form a back-friendly curvature on the textile material side.
