Minimalflächen stellen stets eine optimale Gleichmäßigkeit des Flächenverlaufs bei Vermeidung von Kantenstellen dar.In a preferred embodiment, the seat surface is formed as a minimum surface by a covering, which is clamped between the saddle rails. In this way, the adaptation to the buttocks anatomy further improved and the seating comfort increased. Minimal surfaces always represent optimal uniformity of the surface course while avoiding edge points.
Eine Ausführungsform der Erfindung sieht weiterhin vor, die Bespannung, durch welche die Sitzfläche gebildet ist, mit dem vorderen Sattelholm zwischen einem ersten Ende des vorderen Sattelholms und einem zweiten Ende des vorderen Sattelholms insbesondere durchgehend und ununterbrochen mit dem vorderen Sattelholm entlang eines ersten Befestigungsbereichs zu verbinden und weiterhin die Bespannung, durch welche die Sitzfläche gebildet ist, mit dem hinteren Sattelholm zwischen einem ersten Ende des hinteren Sattelholms und einem zweiten Ende des hinteren Sattelholms durchgehend und ununterbrochen mit dem hinteren Sattelholm entlang eines zweiten Befestigungsbereichs zu verbinden. Hierdurch wird eine optimale Anbindung der Sitzfläche bzw. der die Sitzfläche bildenden Bespannung an den vorderen und den hinteren Sattelholm erreicht, so dass es möglich ist, die Sitzfläche auch aus hochflexiblen und/oder dünnen Materialien wie Geweben oder Folien auszuführen, da diese im Bereich der Sattelholme unterbrechungsfrei gehalten werden. Hierdurch ist es insbesondere möglich, die Zugspannung, welche für die Tragfähigkeit von dünnen Bespannungen einen wesentlichen Faktor darstellt, gleichmäßig auf die Bespannung zu übertragen und ein durch Spannungsspitzen begünstigtes Einreißen der Bespannung zu vermeiden. Erfindungsgemäß ist es vorgesehen, die Bespannung an den Sattelholmen einzuklemmen und ggf. zusätzlich mit diesen zu verkleben und/oder zu verschweißen oder die Bespannung um den vorderen Sattelholm und/oder um den hinteren Sattelholm umzuschlagen und ggf. zusätzlich mit diesem zu verkleben und/oder zu verschweißen.An embodiment of the invention further provides, the string, by which the seat is formed to connect with the front saddle spar between a first end of the front saddle spar and a second end of the front saddle spar, in particular continuously and continuously with the front saddle spar along a first attachment portion and further to connect the string through which the seat is formed to the rear seat post between a first end of the rear seat post and a second end of the rear seat post continuously and continuously with the rear seat post along a second attachment portion. In this way, an optimal connection of the seat or the seat covering forming clothing is achieved on the front and the rear saddle spar, so that it is possible to make the seat even made of highly flexible and / or thin materials such as fabrics or films, as these in the field Saddle rails are kept uninterrupted. This makes it possible in particular, the tensile stress, which for the sustainability of thin fabrics represents an essential factor to transfer evenly to the fabric and to avoid a tipping of the fabric, which is favored by stress peaks. According to the invention it is intended to clamp the fabric to the saddle rails and possibly additionally glued to these and / or to weld or wrap the fabric around the front saddle spar and / or the rear saddle spar and possibly additionally glued to this and / or to weld.
Eine weitere Ausführungsform zeichnet sich dadurch aus, dass die Sitzfläche an den Sattelholmen fest und zwischen den Sattelholmen, insbesondere an Verbindungskanten 9 flexibel ausgebildet ist. Hierbei liegen die Verbindungskanten in einem umlaufenden Randbereich der Sitzfläche dort, wo die Sitzfläche zwischen dem vorderen Sattelholm und dem hinteren Sattelholm verläuft. Hierdurch ist eine optimale Verbindung mit den Sattelholmen möglich. Im Sitzbetrieb des erfindungsgemäßen Sitzmöbels werden die Beine des Sitzenden meist an den Seitenkanten bzw. Verbindungskanten der Sitzfläche anliegen. Durch die flexible Ausgestaltung entstehen dabei keine Druckstellen.Another embodiment is characterized in that the seat is fixed to the saddle rails and between the saddle rails, in particular at connecting edges 9 is flexible. Here are the connecting edges in a peripheral edge region of the seat where the seat between the front saddle spar and the rear saddle spar extends. As a result, an optimal connection with the saddle bars is possible. In the seat operation of the seat according to the invention, the legs of the seated will usually rest against the side edges or connecting edges of the seat. The flexible design creates no pressure points.
Eine weitere Ausführung des Sitzmöbels nach der Erfindung ist, dass die Sitzfläche zwischen den Sattelholmen frei tragend aufgespannt ist. Die Vermeidung von Stützkonstruktionen unter der Sitzfläche verbessert weiterhin den Sitzkomfort, da keine Druckstellen entstehen können und sich die Sitzfläche vollständig flexibel anpasst.Another embodiment of the chair according to the invention is that the seat between the saddle rails is stretched freely. The avoidance of support structures under the seat further improves the comfort of sitting, since no pressure points can arise and the seat adapts completely flexible.
Eine weitere Ausführungsform zeichnet sich dadurch aus, dass die Sitzfläche durch ein Gitternetzgewebe aufgespannt ist, welches eine gute Belüftung erlaubt und insbesondere im Sommer ein angenehmes Sitzen ermöglicht. Hierdurch weist die Bespannung atmungsaktive Eigenschaften auf, so dass vom Körper des Nutzers abgegebene Körperwärme optimal durch die Bespannung hindurch abgeführt werden kann. Weiterhin lässt sich ein Gitternetzgewebe durch die eingesetzte Webtechnik und/oder durch die Eigenschaften des Webfadens optimal auf die Anforderungen auslegen.Another embodiment is characterized in that the seat is spanned by a mesh fabric, which allows good ventilation and allows a comfortable sitting, especially in summer. As a result, the fabric has breathable properties so that body heat released by the user's body can be optimally removed through the fabric. Furthermore, a mesh fabric can be optimally adapted to the requirements by the weaving technique used and / or by the properties of the weaving thread.
Dabei kann es vorgesehen sein, sowohl den ersten Befestigungsbereich einem kurvenförmigen, konvexen Verlauf des vorderen Sattelholms folgen zu lassen, wobei der erste Befestigungsbereich eine erste Länge aufweist, als auch den zweiten Befestigungsbereich einem kurvenförmigen, konvexen Verlauf des hinteren Sattelholms folgen zu lassen, wobei der zweite Befestigungsbereich eine zweite Länge L6 aufweist. Durch die zwei konvex verlaufenden Sattelholme wird die zwischen den Sattelholmen aufgespannte Sattelfläche als zu einem Gesäß des Nutzers hin konvex gewölbte Sattelfläche geformt und nimmt eine einem Reitsattel ähnliche, ergonomisch günstige Form an.It can be provided, both to let follow the first mounting portion a curved, convex course of the front seat spar, wherein the first attachment portion has a first length, and the second attachment portion to follow a curved, convex course of the rear seat spar, said second attachment portion has a second length L6.

Bezüglich der Bespannung sieht eine Ausführungsform vor, diese mit einer Dicke von maximal 3 mm und insbesondere mit einer Dicke von maximal 2 mm auszuführen. Derartige Bespannungen sind in unterschiedlichsten Ausführungen kostengünstig verfügbar und insbesondere lässt sich mit derartigen Bespannungen eine atmungsaktive Ausführung einfach realisieren. Durch eine derartige Bemessung der Bespannung wird die erforderliche Flexibilität der Bespannung auf einfache Weise gewährleistet, so dass die Bespannung ohne Schwierigkeiten der Biegung des vorderen bzw. hinteren Sattelholms folgen kann.With regard to the covering, an embodiment provides for this to be carried out with a maximum thickness of 3 mm and in particular with a maximum thickness of 2 mm. Such fabrics are available in a variety of designs cost and in particular can be easily realized with such fabrics breathable design. Such a dimensioning of the clothing ensures the required flexibility of the clothing in a simple manner, so that the clothing can easily follow the bending of the front or rear seat spar.
Erfindungsgemäss ist es vorgesehen, dass der vordere Sattelholm an der vorderen Holmstütze und der hinteren Sattelholm an der hinteren Holmstütze relativ zueinander verschiebbar, insbesondere über eine Spannvorrichtung im Abstand veränderbar ausgebildet sind. Sofern die Spannvorrichtung eine Spindel und ein Handrad umfasst, ist es durch eine Drehung der Spindel an ihrem Handrad nun möglich, einen Abstand zwischen den beiden Holmstützabschnitten zu vergrößern und so die Bespannung zu spannen oder zu verkleinern und so eine Spannung der Bespannung zu verringern. Die Spannung und damit die Härte der Sitzfläche ist dadurch einstellbar, so dass diese an die individuellen Komfortansprüche und Personenparameter, wie beispielsweise das Körpergewicht und die Sitzposition anpassbar ist.According to the invention, it is provided that the front saddle spar on the front spar support and the rear saddle spar on the rear spar support are displaceable relative to each other, in particular via a tensioning device formed in the distance changeable. If the clamping device comprises a spindle and a handwheel, it is now possible by a rotation of the spindle on its handwheel, to increase a distance between the two spar support sections and so to tension or reduce the clothing and thus to reduce a tension of the fabric. The tension and thus the hardness of the seat is adjustable by so that it is adaptable to individual comfort requirements and personal parameters, such as body weight and sitting position.
Eine überdies zweckmäßige Ausgestaltung des Sitzmöbels ist dadurch gekennzeichnet, dass der vordere Sattelholm und der hintere Sattelholm an ihren Holmenden je eine Schneckenwindung aufweisen, in welche die Sitzfläche eingespannt, insbesondere eingewickelt ist, wobei zwischen den Sattelholmen die Sitzfläche in ihrem Randbereich vorzugsweise um eine Bespannungsführung gewickelt geführt ist. Das "Einwickeln" der Bespannung, welche die Sitzfläche bildet, stellt eine stabile, gegen Einreißen gesicherte Kante bereit, ohne dass zusätzliche Kantenverstärkungen eingebracht werden müssen, welche beispielsweise die Flexibilität verringern. Es ist denkbar, ein Flachmaterial einzuschlagen, welches eine gewisse Führung und Formstabilität für den gewickelten Bereich bereitstellt. An den Holmenden stellt die Schneckenwindung eine vorteilhafte und belastungsgünstige Führung für das Material, welches die Sitzfläche ausbildet, dar, da Kanten vermieden werden. Auf diese Weise ist eine hohe Materialspannung zu realisieren, ohne dass besondere Verstärkungen vorgenommen werden müssen.Moreover, an expedient embodiment of the chair is characterized in that the front saddle spar and the rear saddle spar at their ends each have a helical turn in which the seat is clamped, in particular wrapped, between the saddle rails, the seat preferably wrapped in its edge region to a string guide is guided. The "wrapping" of the fabric forming the seat provides a stable, torn edge without the need for additional edge reinforcements which, for example, reduce flexibility. It is conceivable to strike a flat material, which provides some guidance and dimensional stability for the wound area. At the ends of the spars, the worm winding provides an advantageous and stress-resistant guide for the material that forms the seat, since edges are avoided. In this way, a high material tension can be realized without special reinforcements must be made.
Allgemein stellt insbesondere die Verwendung von punktelastischem Gittergewebe als Bespannungsmaterial eine vorteilhafte Ausführung für die Sitzfläche bereit, welche hohen Komfort bei gleichzeitig gegebener vorteilhafter Stabilität bietet, wenn beispielsweise Punktbelastungen durch Inhalte von Gesäßtaschen (z. B. einen Schlüsselbund) erfolgen.In general, in particular, the use of point-elastic mesh fabric as a covering material provides an advantageous embodiment for the seat surface, which offers high comfort with simultaneously given advantageous stability, for example when point loads occur through contents of back pockets (eg a keychain).
