Im Stand der Technik sind Stühle bekannt, bei denen die Sitzfläche sowie die Rückenlehnenfläche jeweils von einem Gestrick gebildet sind. Dabei sind die Gestricke jeweils zwischen separaten Rohrrahmen gespannt. Der bespannte Rohrrahmen für die Rückenlehne wird dabei auf geeignete Weise mit dem bespannten Rohrrahmen für die Sitzfläche verbunden. Die Herstellung und Bespannung der Sitzfläche und der Rückenlehne erfolgt jeweils separat, die Sitzfläche und die Rückenlehne werden anschließend starr miteinander verbunden.In the prior art chairs are known in which the seat and the backrest surface are each formed by a knit fabric. The knitted fabrics are stretched between separate tubular frames. The covered tubular frame for the backrest is connected in a suitable manner with the covered tubular frame for the seat. The production and covering of the seat and the backrest takes place separately, the seat and the backrest are then rigidly connected.

Die US 200310062756 A1 zeigt eine Rückenlehne, die aus einem Rahmen besteht, der aus zwei c-förmigen Rahmenteilen gebildet wird. Diese werden in einen Randsaum, der sich um den Umfang eines Bezuges erstreckt, eingefügt. Zu diesem Zweck hat der Randsaum wenigstens eine Öffnung. Die Verbindung zwischen den beiden Rahmenteilen wird durch Verbindungsteile erreicht, die zusätzlich die wenigstens eine Öffnung abdecken.The US 200310062756 A1 shows a backrest which consists of a frame which is formed of two C-shaped frame parts. These are inserted into a rim, which extends around the circumference of a cover. For this purpose, the edge seam has at least one opening. The connection between the two frame parts is achieved by connecting parts which additionally cover the at least one opening.

Die DE 1 729 980 zeigt ein gepolstertes Sitzmöbel mit Sitzfläche und Rückenlehne, wobei das Sitzteil aus einem in sich geschlossenen und entsprechend der gewünschten Umrissform gebogenen Rahmen aus einer Profilstange aus federnd elastischem Material besteht. Die von dem Rahmen umschlossene Fläche ist mit elastischem Polstermaterial bespannt.The DE 1 729 980 shows a padded seat with seat and backrest, wherein the seat part consists of a self-contained and curved according to the desired outline shape frame consists of a profile bar made of resilient material. The area enclosed by the frame surface is covered with elastic padding material.

Hierbei ist von Nachteil, dass die Anzahl der vorzusehenden Bauteile sowie die Anzahl der durchzuführenden Fertigungsschritte für einen derartigen Stuhl hoch sind, was die Herstellung eines solchen Stuhles aufwendig und teuer macht.It is disadvantageous that the number of components to be provided and the number of manufacturing steps to be performed for such a chair are high, which makes the manufacture of such a chair expensive and expensive.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Stuhl anzugeben, dessen Sitzfläche und Rückenlehne ein Gestrick aufweisen und bei dem die Anzahl der benötigten Bauteile und der durchzuführenden Fertigungsschritte verringert ist, und der daher einfacher und kostengünstiger hergestellt werden kann. Des Weiteren soll ein Verfahren zur einfachen und kostengünstigen Herstellung eines solchen Stuhls angegeben werden.It is therefore an object of the present invention to provide a chair, the seat and backrest have a knit fabric and in which the number of required components and the manufacturing steps to be performed is reduced, and therefore can be made easier and cheaper. Furthermore, a method for simple and inexpensive production of such a chair is to be specified.

Diese Aufgaben werden durch den Gegenstand der unabhängigen Patentansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich jeweils aus den abhängigen Ansprüchen.These objects are achieved by the subject matter of the independent claims. Advantageous developments emerge in each case from the dependent claims.

Gemäß der Erfindung ist ein einteiliger Sitz mit Rückenlehne für einen Stuhl vorgesehen, der ein gebogenes Schalenrahmen-Rohr, eine Spannstange sowie ein einteiliges Gestrick aufweist. Das gebogene Schalenrahmen-Rohr legt dabei die linke und die rechte Seite der Sitzfläche und der Rückenlehne sowie das obere Ende der Rückenlehne fest und weist zwei Enden auf, zwischen denen die Spannstange eingesetzt ist. Die die linke und die rechte Seite der Sitzfläche und der Rückenlehne bildenden Abschnitte des gebogenen Schalenrahmen-Rohrs können auch als Seiten holme, der das obere Ende der Rückenlehne festlegende Abschnitt des gebogenen Schalenrahmen-Rohrs kann auch als Querholm bezeichnet werden. Das einteilige Gestrick verfügt über einen integrierten umlaufenden Kedersaum, in dem das Schalenrahmen-Rohr und die Spannstange eingefädelt sind und dort verlaufen. Damit das Schalenrahmen-Rohr und die Spannstange in den umlaufenden Kedersaum eingefädelt werden können, ist an der Unterseite des einteiligen Gestricks an einem Rand wenigstens eine Öffnung vorgesehen.According to the invention, a one-piece seat with backrest for a chair is provided, which has a bent shell frame tube, a tie rod and a one-piece knitted fabric. The bent shell frame tube defines the left and right sides of the seat and the backrest and the upper end of the backrest and has two ends, between which the tie rod is inserted. The left and right side of the seat and the backrest forming portions of the curved shell frame tube may also be referred to as side spars, the upper end of the backrest defining portion of the curved shell frame tube may also be referred to as a transverse spar. The one-piece knitted fabric has an integrated circumferential welt hem in which the shell frame tube and the tension rod are threaded and run there. So that the shell frame tube and the tie rod can be threaded into the circumferential Kedersaum, at least one opening is provided on the underside of the one-piece knitted fabric at one edge.

Gemäß einem Grundgedanken der Erfindung wird durch eine derartige Konstruktion ein einteiliger Sitz mit einer Sitzfläche und mit einer Rückenlehne bereitgestellt, bei dem sich ein einziges Gestrick durchgängig über die Sitzfläche und über die Rückenlehne erstreckt, und zwar in der Form, dass der umlaufende Kedersaum in einem vorderen, später verdeckten Unterseiten-Bereich wenigstens eine Öffnung aufweist, durch welche das gesamte Schalenrahmen-Rohr und die Spannstange eingefädelt werden. Es brauchen keine separaten Gestricke mehr für Sitzfläche und Rückenlehne vorgesehen zu werden.According to a basic idea of the invention, such a construction provides a one-piece seat with a seat surface and with a backrest, in which a single knit extends continuously over the seat surface and over the backrest, in the form that the circumferential welt seams in one front, later concealed bottom portion has at least one opening through which the entire shell frame tube and the tension rod are threaded. There is no need to provide separate knits for the seat and backrest.

Des Weiteren weist ein derartiger einteiliger Sitz mit Rückenlehne eine außergewöhnlich zarte Gestalt und besondere Formschönheit auf. Dadurch, dass sowohl das gebogene Schalenrahmen-Rohr als auch die Spannstange in den umlaufenden Kedersaum durch dessen wenigstens eine Öffnung eingefädelt werden können, ergibt sich eine besonders einfache Herstellung des einteiligen Sitzes mit Rückenlehne, wobei ein zusätzliches Vernähen des einteiligen Gestrickes kostensparenderweise vermieden werden kann. Dadurch, dass die wenigstens eine Öffnung des Kedersaums an der Unterseite des einteiligen Gestricks angeordnet ist, bleibt diese für einen Benutzer unsichtbar. Dementsprechend bleibt dem Nutzer verborgen, auf welche Weise der Schalenrahmen in das einteilige Gestrick gelangt ist.Furthermore, such a one-piece seat with backrest on an exceptionally delicate shape and special beauty of form. The fact that both the curved shell frame tube and the tie rod can be threaded through the at least one opening in the circumferential Kedersaum, results in a particularly simple production of the one-piece seat with backrest, with additional sewing of the one-piece knitted fabric can be avoided cost-effectively. Characterized in that the at least one opening of the Kedersaums is arranged on the underside of the one-piece knitted fabric, this remains invisible to a user. Accordingly, it remains hidden to the user, in which way the shell frame has entered the one-piece knitted fabric.

Gemäß einer ersten Ausführungsform der Erfindung weist der umlaufende Kedersaum an seiner Unterseite zwei Öffnungen auf, um das Schalenrahmen-Rohr und die Spannstange vorteilhaft einfädeln zu können. Diese zwei Öffnungen können links und rechts in einem vorderen Randbereich der Unterseite des einteiligen Gestricks vorgesehen sein. Diese sind dann vollkommen unsichtbar, wenn der einteilige Sitz mit Rückenlehne auf ein Stuhlgestell montiert wird.According to a first embodiment of the invention, the circumferential Kedersaum on its underside on two openings in order to thread the shell frame tube and the tie rod advantageous. These two openings can be provided left and right in a front edge region of the underside of the one-piece knitted fabric. These are completely invisible when the one-piece seat with backrest is mounted on a chair frame.

Durch die erfindungsgemäße Konstruktion des einteiligen Sitzes mit Rückenlehne kann das einteilige Gestrick einlagig ausgebildet sein. Seine Form und seine Abmessungen werden durch die Kontur des gebogenen Schalenrahmen-Rohrs und der Spannstange festgelegt. In der Regel weist das einteilige Gestrick eine im Wesentlichen rechteckige Form auf.Due to the construction according to the invention of the one-piece seat with backrest, the one-piece knitted fabric can be formed in one layer. Its shape and dimensions are determined by the contour of the curved shell frame tube and the tie rod set. In general, the one-piece knit has a substantially rectangular shape.

Die Erfindung betrifft auch einen Stuhl, bei dem der vorstehend beschriebene einteilige Sitz mit Rückenlehne, insbesondere die Seitenholme dessen Schalenrahmen-Rohrs an zwei Gestellschenkeln eines darunter angeordneten Stuhlgestells befestigt ist. Dabei ist weiterhin ein Stützteil in einem vorderen Bereich des Stuhlgestells unterhalb des einteiligen Gestricks angeordnet, um ein Einfallen des Gestricks zu vermeiden und um die Stützkraft für die in einem vorderen Bereich der Sitzfläche aufliegenden Oberschenkel zu erhöhen. Dieses Stützteil kann grundsätzlich aus einem beliebigen Material hergestellt sein. Der Sitzkomfort kann verbessert werden, wenn das Stützteil aus einem flexiblen Material ist.The invention also relates to a chair in which the above-described one-piece seat with backrest, in particular the side rails of the shell frame tube is attached to two frame legs of a chair frame arranged underneath. In this case, a support member is further arranged in a front region of the chair frame below the one-piece knitted fabric to prevent collapse of the knitted fabric and to increase the supporting force for resting in a front region of the seat thigh. This support member can in principle be made of any material. The seating comfort can be improved when the support member is made of a flexible material.

Eine besonders stabile und einfach herzustellende Konstruktion des Stuhles ist dann gegeben, wenn das Stützteil zwischen den Gestellschenkeln befestigt, insbesondere verschraubt ist. Dann kann sogar auf eine Querstrebe zwischen den Gestellschenkeln des Stuhlgestells an dieser Stelle verzichtet werden.A particularly stable and easy to manufacture construction of the chair is given when the support member between the frame legs attached, in particular screwed. Then even can be dispensed with a cross strut between the frame legs of the chair frame at this point.

Die Erfindung betrifft auch ein Verfahren zum Herstellen eines einteiligen Sitzes mit Rückenlehne für einen Stuhl. Dabei werden zunächst ein bereits oben beschriebenes gebogenes Schalenrahmen-Rohr sowie ein bereits oben beschriebenes einteiliges Gestrick bereitgestellt. Das gebogene Schalenrahmen-Rohr wird dann durch wenigstens eine der Öffnungen des umlaufenden Kedersaums in den Kedersaum vollständig eingefädelt. Danach oder gleichzeitig wird das gebogene Schalenrahmen-Rohr mit dem einteiligen Gestrick bespannt, sodass sowohl die Rückenlehne als auch die Sitzfläche durchgängig von dem einteiligen Gestrick aufgespannt sind. Nun wird eine bereits oben erwähnte Spannstange bereitgestellt und ebenfalls durch wenigstens eine der Öffnungen des umlaufenden Kedersaums in diesen eingefädelt. Schließlich wird die Spannstange zwischen die zwei Enden des Schalenrahmen-Rohrs eingesetzt. Dafür kann es erforderlich sein, die Seitenholme des gebogenen Schalenrahmen-Rohrs auseinander zu spannen, weil sich das gebogene Schalenrahmen-Rohr durch die von dem einteiligen Gestrick ausgeübte Spannung rechts- und linksseitig nachgebend zusammenzieht. Durch die Spannstange wird das gebogene Schalenrahmen-Rohr fixiert und die gesamte Form des einteiligen Sitzes mit Rückenlehne festgelegt. Durch dieses Herstellungsverfahren kann ein einteiliger Sitz mit Rückenlehne schnell, einfach und auf kostengünstige Weise hergestellt werden.The invention also relates to a method for producing a one-piece seat with backrest for a chair. Initially, a bent shell frame tube already described above and a one-piece knit fabric already described above are provided. The bent shell frame tube is then fully threaded through at least one of the openings of the circumferential welt space in the welt space. Thereafter or at the same time, the bent shell frame tube is covered with the one-piece knit so that both the backrest and the seat surface are continuously stretched by the one-piece knitted fabric. Now, an already mentioned above tension rod is provided and also threaded through at least one of the openings of the circumferential Kedersaums in this. Finally, the tie rod is inserted between the two ends of the shell frame tube. For this it may be necessary to spread apart the side rails of the curved shell frame tube, because the bent shell frame tube contractively contracts due to the tension exerted by the one-piece fabric on the right and left side. By the tie rod, the curved shell frame tube is fixed and fixed the entire shape of the one-piece seat with backrest. By this manufacturing method, a one-piece seat with backrest can be made quickly, easily and inexpensively.

Um eine gleichmäßige Kräfteverteilung beim Herstellen des einteiligen Sitzes mit Rückenlehne zu gewährleisten, und um gleichzeitig ein Verbiegen des gebogenen Schalenrahmen-Rohrs zu verhindern, kann der Schritt des Bespannens des Schalenrahmen-Rohrs mit dem einteiligen Gestrick durchgeführt werden, indem zunächst das einteilige Gestrick als Ganzes über den das obere Ende der Rückenlehne festlegenden Querholm des Schalenrahmen-Rohrs gerafft wird und anschließend das einteilige Gestrick parallel rechts und links über die Seitenholme des Schalenrahmen-Rohrs heruntergestreift wird. Dieses Herunterstreifen wird bis nach vorne fortgesetzt. Dadurch wird das einteilige Gestrick besonders gleichmäßig straff gespannt. Dabei ist es erforderlich, dass das einteilige Gestrick aus flexiblem Material ist.In order to ensure a uniform distribution of forces in the production of the one-piece seat with backrest, and at the same time to prevent bending of the bent shell frame tube, the step of covering the shell frame tube with the one-piece fabric can be performed by first the one-piece knitted fabric as a whole over which the upper end of the backrest defining cross member of the shell frame tube is shirred and then the one-piece knit fabric is stripped down parallel right and left on the side rails of the shell frame tube. This stripping continues to the front. As a result, the one-piece fabric is stretched particularly evenly taut. It is necessary that the one-piece knitted fabric is made of flexible material.

Die Erfindung betrifft schließlich ein Verfahren zum Herstellen eines Stuhls, bei dem zunächst das oben beschriebene Verfahren zum Herstellen eines einteiligen Sitzes mit Rückenlehne durchgeführt wird. Dann werden ein Stuhlgestell mit zwei Gestellschenkeln bereitgestellt und ein insbesondere flexibles Stützteil auf der Oberseite des Stuhlgestells zwischen den zwei Gestellschenkeln angebracht. Alternativ dazu kann das Stuhlgestell schon mit einem solchen Stützteil zur Verfügung gestellt werden. Schließlich wird der einteilige Sitz mit Rückenlehne auf dem Stuhlgestell befestigt.Finally, the invention relates to a method for manufacturing a chair, in which first the method described above for producing a one-piece seat with backrest is carried out. Then a chair frame with two frame legs are provided and a particular flexible support member mounted on top of the chair frame between the two frame legs. Alternatively, the chair frame can already be made available with such a support member. Finally, the one-piece seat is fixed with backrest on the chair frame.

Mit diesem Herstellungsverfahren kann ein besonders formschöner und komfortabler Schalenrahmen-Stuhl kostengünstig, schnell und auf einfache Weise hergestellt werden.With this manufacturing method, a particularly shapely and comfortable shell frame chair can be produced inexpensively, quickly and easily.

Um den Schalenrahmen optimal zu spannen, können beim Befestigen des einteiligen Sitzes mit Rückenlehne auf dem Stuhlgestell die seitlichen Holme des Schalenrahmen-Rohrs insbesondere mit Hilfe einer entsprechenden Vorrichtung auseinander gespannt werden.In order to optimally tension the shell frame, the side uprights of the shell frame tube can be stretched apart, in particular with the aid of a corresponding device when fastening the one-piece seat with backrest on the chair frame.

Eine besonders stabile und kostengünstig realisierbare Befestigung des einteiligen Sitzes mit Rückenlehne auf dem Stuhlgestell ist dann gegeben, wenn die seitlichen Holme des Schalenrahmen-Rohrs mit den Gestellschenkeln verschraubt werden.A particularly stable and inexpensive realizable attachment of the one-piece seat with backrest on the chair frame is given when the side rails of the shell frame tube are bolted to the frame legs.

Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels mit Bezug auf die Figuren 1 und 2 näher veranschaulicht.The invention is based on an embodiment with reference to the FIGS. 1 and 2 illustrated in more detail.

Der in Figur 1 gezeigte Schalenrahmen-Stuhl verfügt über ein Stuhlgestell 3, über ein Stützteil 5 und über ein gebogenes Schalenrahmen-Rohr 1, das mit seinen Seitenholmen die linke und rechte Seite der Sitzfläche und der Rückenlehne sowie mit seinem Querholm das obere Ende der Rückenlehne festlegt. Das Stuhlgestell 3 umfasst zwei zueinander parallel verlaufende Gestellschenkel 3a und 3b, die jeweils einen auf dem Boden aufliegenden Abschnitt, einen senkrecht nach oben verlaufenden Abschnitt und einen das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitt aufweisen. Die das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitte der Gestellschenkel 3a und 3b sind an ihrem Ende mit einer nach unten gebogenen Querverstrebung verbunden. Die auf dem Boden aufliegenden Abschnitte der Gestellschenkel 3a und 3b sind an ihrem Ende mit einer auf dem Boden aufliegenden Querverstrebung verbunden. Die Übergänge zwischen den auf den Boden aufliegenden Abschnitten, den senkrecht nach oben verlaufenden Abschnitten und den das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitten der Gestellschenkel 3a und 3b sind jeweils abgerundet ausgebildet.The in FIG. 1 shown cup frame chair has a chair frame 3, a support member 5 and a curved shell frame tube 1, which defines with its side rails the left and right side of the seat and the backrest and with its transverse spar the upper end of the backrest. The chair frame 3 comprises two mutually parallel frame legs 3a and 3b, each having a resting on the floor portion, a vertically upwardly extending portion and a bent shell frame tube 1 bearing portion. The bent shell frame tube 1 supporting portions of the frame legs 3a and 3b are connected at its end with a downwardly bent cross-brace. The resting on the floor portions of the frame legs 3a and 3b are connected at its end with a resting on the floor cross brace. The transitions between the resting on the floor sections, the vertically upwardly extending portions and the bent shell frame tube 1 bearing portions of the frame legs 3a and 3b are each rounded.

Auf den das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitten der Gestellschenkel 3a und 3b liegen die Seitenholme 1b und 1c des gebogenen Schalenrahmen-Rohrs 1 auf. Diese Seitenholme 1b und 1c sind dabei von unten mit den das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitten der Gestellschenkel 3a und 3b verschraubt. Die Schraubenköpfe dieser Schraubverbindungen sind in Figur 1 an der Unterseite der das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitte der Gestellschenkel 3a und 3b zu sehen.On the bent shell frame tube 1 supporting portions of the frame legs 3a and 3b are the side rails 1b and 1c of the curved shell frame tube 1 on. These side rails 1b and 1c are screwed from below with the bent shell frame tube 1 bearing portions of the frame legs 3a and 3b. The screw heads of these screw connections are in FIG. 1 to see at the bottom of the curved shell frame tube 1 bearing portions of the frame legs 3a and 3b.

In einem vorderen Bereich der Sitzfläche ist ein plattenförmiges, in vorderer Richtung leicht nach unten gebogenes Stützteil 5 vorgesehen, das der Krümmung der Gestellschenkel 3a und 3b folgt und das sich zwischen den Seitenholmen 1b und 1c erstreckt.In a front portion of the seat, there is provided a plate-shaped support member 5 slightly bent in the front direction, which follows the curvature of the frame legs 3a and 3b and which extends between the side rails 1b and 1c.

Die Seitenholme 1b und 1c sind am rückwärtigen Ende der Sitzfläche nach oben gebogen und verlaufen S-förmig bis zu dem Querholm 1a, der sie verbindet, nach oben.The side rails 1b and 1c are bent upwards at the rear end of the seat surface and extend upwards in an S-shape as far as the cross member 1a connecting them.

Der Schalenrahmen-Stuhl ist mit einem einteiligen Gestrick 4 versehen, das aus Darstellungsgründen in Figur 1 nur in einem oberen Bereich der Rückenlehne gezeigt ist. Das einteilige Gestrick 4 erstreckt sich zwischen den Seitenholmen 1b und 1c und dem oberen Querholm 1a des gebogenen Schalenrahmen-Rohrs 1.The shell frame chair is provided with a one-piece knitted fabric 4, which for purposes of illustration in FIG. 1 is shown only in an upper region of the backrest. The one-piece knitted fabric 4 extends between the side rails 1b and 1c and the upper cross member 1a of the bent shell frame pipe 1.

Figur 2 zeigt eine Explosionszeichnung des Schalenrahmen-Stuhls. Die erfindungsgemäßen Bestandteile des Schalenrahmen-Stuhls, nämlich das Stuhlgestell 3, das Stützteil 5, das gebogene Schalenrahmen-Rohr 1, das einteilige Gestrick 4 und eine Spannstange 2 sind in Figur 2 separat von einander vor ihrem Zusammenbau zu dem Schalenrahmen-Stuhl gezeigt. FIG. 2 shows an exploded view of the shell frame chair. The components according to the invention of the shell frame chair, namely the chair frame 3, the support member 5, the bent shell frame tube 1, the one-piece knitted fabric 4 and a tension rod 2 are in FIG. 2 shown separately from each other before their assembly to the shell frame chair.

Bei dem Stuhlgestell 3 ist zwischen den Gestellschenkeln 3a und 3b eine weitere Querverstrebung zu sehen, die direkt unterhalb des gebogenen Übergangs zwischen den senkrecht nach oben verlaufenden Abschnitten und den das gebogene Schalenrahmen-Rohr 1 tragenden Abschnitten der Gestellschenkel 3a und 3b angeordnet ist. Diese weitere Querverstrebung ist so positioniert, dass das Stützteil 5 mit seiner leicht nach unten gerichteten Frontfläche auf ihr aufliegt, wenn das Stützteil 5 mit seitlich durch die Gestellschenkel 3a und 3b einzubringenden Schrauben mit dem Stuhlgestell 3 verbunden wird.In the chair frame 3 is between the frame legs 3a and 3b, a further cross-brace can be seen, which is located directly below the curved transition between the vertically upwardly extending portions and the bent shell frame tube 1 supporting portions of the frame legs 3a and 3b. This further cross-brace is positioned so that the support member 5 rests with its slightly downwardly facing front surface on her when the support member 5 is connected to be introduced laterally by the frame legs 3a and 3b screws with the chair frame 3.

Die Spannstange 2 weist an ihren Enden kleiner abgesetzte Stutzen auf, die in die Enden des Schalenrahmen-Rohrs 1 eingesetzt werden und das gebogene Schalenrahmen-Rohr 1 so fixieren können.The tension rod 2 has at its ends smaller stepped sockets, which are inserted into the ends of the shell frame tube 1 and the curved shell frame tube 1 can fix so.

Das einteilige Gestrick 4 weist einen umlaufenden Kedersaum 4a auf, der in Figur 2 durch eine gestrichelte Linie dargestellt ist und der auf der Unterseite des einteiligen Gestricks 4 vorne links und rechts zwei Öffnungen 4b und 4c aufweist, durch welche das gebogene Schalenrahmen-Rohr 1 und die Spannstange 2 in den Kedersaum 4a eingefädelt werden können.The one-piece knitted fabric 4 has a circumferential Kedersaum 4a, which in FIG. 2 is shown by a dashed line and has on the underside of the one-piece knitted fabric 4 front left and right two openings 4b and 4c, through which the curved shell frame tube 1 and the tension rod 2 can be threaded into the welt space 4a.

Der in den Figuren 1 und 2 dargestellte erfindungsgemäße Schalenrahmen-Stuhl wird wie folgt aus den in Figur 2 dargestellten Bauteilen zusammengebaut:The in the FIGS. 1 and 2 illustrated tray frame chair according to the invention is as follows from in FIG. 2 Assembled components are assembled:

Zunächst wird das gebogene Schalenrahmen-Rohr 1 durch eine der beiden Öffnungen 4b oder 4c in den umlaufenden Kedersaum 4a eingefädelt. Dann wird das komplette einteilige Gestrick 4 gerafft zunächst als Ganzes über den Querholm 1a des Schalenrahmen-Rohrs 1 zusammengezogen. Anschließend wird das einteilige Gestrick 4 parallel rechts und links über die Seitenholme 1b und 1c heruntergestreift, wobei sich das einteilige Gestrick 4 auf dem gebogenen Schalenrahmen-Rohr 1 straff spannt. Das Herunterstreifen wird bis nach vorne fortgesetzt. Danach führt man die Spannstange 2 vorne durch eine der Öffnungen 4b oder 4c in den Kedersaum 4a ein und spannt das einteilige Gestrick 4 auch nach vorne straff. Durch die Spannung zieht sich die Spannstange 2 mit ihren kleiner abgesetzten Stutzen in das gebogene Schalen rahmen-Rohr 1 und fixiert so die Sitzfläche und die Rückenlehne.First, the bent shell frame tube 1 is threaded through one of the two openings 4b or 4c in the circumferential welt space 4a. Then, the entire one-piece knitted fabric 4 is gathered first as a whole pulled together over the cross member 1a of the shell frame tube 1. Subsequently, the one-piece knitted fabric 4 is pulled down in parallel right and left on the side rails 1b and 1c, with the one-piece fabric 4 taut on the curved shell frame tube 1. The stripping continues until the front. Then you introduce the tension rod 2 front through one of the openings 4b or 4c in the welt space 4a and spans the one-piece fabric 4 also forward taut. Due to the tension, the tension rod 2 pulls with their smaller set neck in the curved shell frame tube 1 and thus fixes the seat and the backrest.

Anschließend wird das Stützteil 5 auf der Oberseite des Stuhlgestells 3 zwischen den zwei Gestellschenkeln 3a und 3b auf die weitere Querverstrebung aufgesetzt und seitlich verschraubt. Das mit dem einteiligen Gestrick 4 bespannte und von der Spannstange 2 fixierte Schalenrahmen-Rohr 1 wird nun auf die Gestellschenkel 3a und 3b aufgesetzt und mit diesen von unten verschraubt.Subsequently, the support member 5 is placed on the top of the chair frame 3 between the two frame legs 3a and 3b on the further cross bracing and screwed laterally. The covered with the one-piece fabric 4 and fixed by the tie rod 2 shell frame tube 1 is now placed on the frame legs 3a and 3b and bolted to them from below.

Der so hergestellte erfindungsgemäße Schalenrahmen-Stuhl weist eine außergewöhnlich zarte Gestalt auf, denn er ist durchgängig mit einem einzigen einteiligen Gestrick 4 bespannt und das Stützteil 5 verbirgt sich zwischen den Gestellschenkeln 3a und 3b. Die Öffnungen 4b und 4c des einlagigen Gestricks 4 sind nicht sichtbar. Dementsprechend bleibt es dem Benutzer verborgen, auf welche Weise das gebogene Schalenrahmen-Rohr 1 in das einteilige Gestrick 4 gelangt ist, was das Design des Schalenrahmen-Stuhls weiter verbessert.The tray frame chair according to the invention thus produced has an exceptionally delicate shape, because it is continuously covered with a single one-piece knitted fabric 4 and the support member 5 is hidden between the frame legs 3a and 3b. The openings 4b and 4c of the single layer knitted fabric 4 are not visible. Accordingly, it remains hidden to the user, in which way the curved shell frame tube 1 has entered the one-piece knit 4, which further improves the design of the shell frame chair.
