Das Sitzmöbel hat einen Sitzteil 1 und einen Rückenteil 2. Der Sitzteil 1 hat einen Rohrrahmen 3, der zwei zueinander parallele Rahmenteile 4 und 5 aufweist, die jeweils bogenförmig in einen vorderen Rahmenteil 6 übergehen. Die seitlichen Rahmenteile 4, 5 verlaufen gerade und sind vom vorderen Rahmenteil 6 aus in Richtung auf den Rückenteil 2 leicht nach unten geneigt (Fig. 3). Der vordere Rahmenteil 6 ist konkav gekrümmt (Fig. 2) und symmetrisch zur Längsmittelebene 7 (Fig. 2) des Sitzmöbels ausgebildet. Der Rohrrahmen 3 hat vorteilhaft kreisförmigen Querschnitt, so daß er beim Sitzen nicht stört.The seating furniture has a seat part 1 and a back part 2. The seat part 1 has a tubular frame 3, the two to each other parallel frame parts 4 and 5, each merge into a front frame part 6. The side frame parts 4, 5 run straight and are from the front frame part 6 in the direction of the back part 2 slightly inclined downwards (Fig. 3). Of the front frame part 6 is concavely curved (Fig. 2) and symmetrical to the longitudinal center plane 7 (Fig. 2) of the seating educated. The tubular frame 3 has advantageous circular cross-section so that it does not sit disturbs.

Der Rohrrahmen 3 geht in einen Rohrrahmen 8 des Rückenteils 2 über. Er hat zwei seitliche, in der gleichen Ebene mit den Rahmenteilen 4, 5 des Sitzteiles 1 liegende Rahmenteile 9 und 10, die gerade verlaufen und vom Sitzteil 1 aus schräg nach hinten geneigt sind. Die seitlichen Rahmenteile 9, 10 gehen bogenförmig in einen oberen Rahmenteil 11 über, der in Vorderansicht gemäß Fig. 2 konkav gekrümmt verläuft und ebenso wie der vordere Rahmenteil 6 des Sitzteiles 1 symmetrisch zur Längsmittelebene 7 des Sitzmöbels verläuft. Während der vordere Rahmenteil 6 des Rohrrahmens 3, in Draufsicht auf den Sitzteil 1 gesehen (Fig. 4), gerade verläuft, ist der Rahmenteil 11 in Draufsicht (Fig. 4) bogenförmig ausgebildet. Der Krümmungsradius des Rahmenteiles 11 ist so gewählt, daß die auf dem Sitzmöbel sitzende Person am Rücken optimal abgestützt wird. Der obere Rahmenteil 11 liegt, wie Fig. 3 zeigt, in einer Ebene, die senkrecht zu einer die seitlichen Rahmenteile 9, 10 des Rückenteiles 2 enthaltenden Ebene verläuft.The tubular frame 3 goes into a tubular frame 8 of the back part 2 over. It has two sides, in the same one Level with the frame parts 4, 5 of the seat part 1 lying Frame parts 9 and 10, which run straight and from Seat part 1 are inclined backwards. The lateral frame parts 9, 10 go arcuately into one upper frame part 11 above, according to the front view Fig. 2 is concave and curved as well as the front Frame part 6 of the seat part 1 symmetrical Longitudinal center plane 7 of the seating furniture runs. During the front frame part 6 of the tubular frame 3, in plan view seen on the seat part 1 (Fig. 4), runs straight, the frame part 11 is curved in plan view (FIG. 4) educated. The radius of curvature of the frame part 11 is chosen so that the person sitting on the seating on Back is optimally supported. The upper frame part 11 3, in a plane that is perpendicular to one of the side frame parts 9, 10 of the back part 2 containing level runs.

Damit die auf dem Sitzmöbel sitzende Person optimal und körpergerecht abgestützt wird, sind die Rahmenteile 6 und 11 des Sitzteiles 1 und des Rückenteiles 2 unterschiedlich gebogen. Der vordere Rahmenteil 6, der nach unten durchgebogen ist (Fig. 2 und 3), hat einen größeren Krümmungsradius als der obere Rahmenteil 11.So that the person sitting on the seating furniture is optimal and the frame parts are 6 and 11 of the seat part 1 and the back part 2 different bent. The front frame part 6, the after is bent below (Fig. 2 and 3), has a larger Radius of curvature as the upper frame part 11.

Die seitlichen Rahmenteile 9, 10 des Rohrrahmens 8 sind etwa in halber Länge durch eine Querstrebe 12 (Fig. 2) miteinander verbunden, deren Enden an den einander zugewandten Seiten der Rahmenteile 9, 10 befestigt, vorzugsweise angeschweißt sind. Die Querstrebe 12 hat, wie sich aus den Fig. 2 und 6 ergibt, eckigen Querschnitt und weist an ihrer vom Sitzteil 1 abgewandten Rückseite eine über ihre Länge sich erstreckende Vertiefung 13 auf, die sich vom oberen Rand 14 der Querstrebe aus erstreckt. Die Tiefe dieser Vertiefung 13 entspricht wenigstens dem Durchmesser von Drähten 15 eines die Rückenfläche 16 bildenden Drahtgitters. Im dargestellten Ausführungsbeispiel wird dieses Drahtgitter 16 durch annähernd senkrecht einander kreuzende Drähte 15 und 17 gebildet, von denen die Drähte 15 von der Querstrebe 12 aus bis zum oberen Rahmenteil 11 parallel zueinander verlaufen. Die Drähte 17 erstrecken sich zwischen den seitlichen Rahmenteilen 9 und 10 des Rohrrahmens 8. Die Rückenfläche 16 ist entsprechend dem oberen Rahmenteil 11 nach hinten gewölbt (Fig. 3), wobei die Krümmung der Rückenfläche 16 über deren Höhe konstant ist. Die Querstrebe 12 ist in gleicher Weise gekrümmt (Fig. 3) wie der obere Rahmenteil 11. Wie Fig. 3 zeigt, liegt die Querstrebe 12 in einer Ebene, die senkrecht zu der die seitlichen Rahmenteile 9, 10 enthaltenden Ebene verläuft. Die Querstrebe 12 liegt parallel zum oberen Rahmenteil 11, erstreckt sich jedoch weniger weit nach hinten als der Rahmenteil 11. In Vorderansicht gemäß Fig. 2 ist die Querstrebe 12 über ihre Länge konvex gekrümmt, allerdings weniger stark als der obere Rahmenteil 11 und der vordere Rahmenteil 6. Aus Fig. 2 ergibt sich weiter, daß der vordere Rahmenteil 6, in Vorderansicht gesehen, stärker gekrümmt verläuft als der obere Rahmenteil 11.The lateral frame parts 9, 10 of the tubular frame 8 are about half the length by a cross strut 12 (FIG. 2) interconnected, the ends of which face each other Sides of the frame parts 9, 10 attached, preferably are welded on. The cross strut 12 has how 2 and 6 results in angular cross section and has on its back facing away from the seat part 1 over its length extending recess 13 on the extends from the upper edge 14 of the cross strut. The depth of this recess 13 corresponds at least to that Diameter of wires 15 of the back surface 16 forming wire mesh. In the illustrated embodiment is this wire mesh 16 by approximately perpendicular intersecting wires 15 and 17 formed by which the wires 15 from the cross strut 12 to upper frame part 11 run parallel to each other. The Wires 17 extend between the side frame parts 9 and 10 of the tubular frame 8. The back surface 16 is corresponding to the upper frame part 11 to the rear arched (Fig. 3), the curvature of the back surface 16 is constant over its height. The cross strut 12 is in curved in the same way (Fig. 3) as the upper frame part 11. As shown in FIG. 3, the cross strut 12 lies in a plane that is perpendicular to that of the side frame parts 9, 10 containing plane runs. The cross strut 12 is parallel to the upper frame part 11, extends however, less far back than the frame part 11. In the front view according to FIG. 2, the cross strut 12 convexly curved over its length, but less so strong than the upper frame part 11 and the front frame part 6. From Fig. 2 it also follows that the front Frame part 6, seen in front view, more curved runs as the upper frame part 11.

Die oberen Enden 18 der aufwärts verlaufenden Drähte 15 der Rückenfläche 16 sind rechtwinklig nach hinten abgebogen (Fig. 3) und an der Unterseite des oberen Rahmenteiles 11 befestigt, vorzugsweise angeschweißt. Die Drähte 15 liegen mit ihren unteren Enden in der Vertiefung 13 der Querstrebe 12. Diese Drahtenden sind an der in Höhenrichtung verlaufenden, vom Rückenteil 2 abgewandten ebenen Rückseite 19 der Vertiefung 13 befestigt, vorzugsweise angeschweißt (Fig. 3 und 6). Die Drähte 15 sind vorteilhaft so lang, daß sie mit ihren unteren Enden außerdem auf dem senkrecht zur Rückseite 19 verlaufenden Boden 20 der Vertiefung 13 aufsitzen.The upper ends 18 of the upward wires 15 the back surface 16 are bent backwards at right angles (Fig. 3) and on the underside of the upper frame part 11 attached, preferably welded. The The lower ends of wires 15 lie in the depression 13 of the cross strut 12. These wire ends are on the extending in the vertical direction, facing away from the back part 2 flat back 19 of the recess 13 attached, preferably welded (Fig. 3 and 6). The wires 15 are advantageous so long that they have their lower ends also on the perpendicular to the back 19 Sit on the bottom 20 of the recess 13.

Die oberen, rechtwinklig abgebogenen Enden 18 der Drähte 15 erstrecken sich etwa bis in Höhe des halben Durchmessers des oberen Rahmenteiles 11. Dadurch können sie einerseits sicher an der Unterseite des Rahmenteiles 11 befestigt werden, andererseits stehen sie nicht nach hinten über den Rahmenteil 11 über. Da die Drahtenden 18 an der Unterseite des Rahmenteiles 11 befestigt sind, müssen sie anschließend nicht in einem gesonderten Arbeitsgang abgetrennt werden, wie dies bei herkömmlichen Sitzmöbeln mit Drahtgittern als Rückenfläche notwendig ist. Da die Drahtenden 18 nicht über den Rahmenteil 11 überstehen, besteht auch nicht die Gefahr, daß Kleider beim Sitzen auf dem Möbel beschädigt werden. Da die Vertiefung 13 in der Querstrebe 12 auf der von der Rückenfläche abgewandten Seite vorgesehen ist, liegen die unteren Drahtenden ebenfalls verdeckt, so daß sie die Kleidung ebenfalls nicht beschädigen können.The upper, right-angled ends 18 of the wires 15 extend approximately to the height of half the diameter of the upper frame part 11. This allows them on the one hand securely on the underside of the frame part 11 are attached, on the other hand they are not inferior rear over the frame part 11 over. Since the wire ends 18th are attached to the underside of the frame part 11, you then do not have to do it in a separate operation be separated, as in conventional Seating with wire mesh is necessary as the back surface is. Since the wire ends 18 do not have the frame part 11 survive, there is no risk that clothes damaged when sitting on the furniture. Because the deepening 13 in the cross strut 12 on the back surface the lower side is provided Wire ends also covered, so that they the Can not damage clothing either.

Die etwa parallel zur Querstrebe 12 verlaufenden Drähte 17 sind an beiden Enden rechtwinklig abgebogen. In Fig. 6 ist das eine Ende 21 des Drahtes 17 dargestellt. Das andere Drahtende ist entsprechend rechtwinklig abgebogen. Auch diese Drahtenden 21 sind in bezug auf die Rückenfläche 16 nach hinten gebogen, so daß nicht die Gefahr besteht, daß sie die Kleidung beschädigen. Diese Drahtenden 21 sind an den einander zugewandten Innenseiten der seitlichen Rahmenteile 9 und 10 befestigt, vorzugsweise angeschweißt. Diese Drahtenden erstrecken sich über etwas mehr als den halben Durchmesser der Rahmenteile 9, 10 nach hinten. Dadurch stehen die Drahtenden 21 nicht nach hinten über den Rohrrahmen 8. Somit müssen auch diese Drähte 17 nicht in einem gesonderten Arbeitsgang an ihren Enden abgetrennt werden.The wires running approximately parallel to the cross strut 12 17 are bent at right angles at both ends. In Fig. 6, one end 21 of the wire 17 is shown. The other wire end is bent accordingly at right angles. These wire ends 21 are also in relation to the back surface 16 bent back so that there is no danger is that they damage clothing. This Wire ends 21 are on the mutually facing inner sides the side frame parts 9 and 10 attached, preferably welded on. These wire ends extend over a little more than half the diameter of the frame parts 9, 10 to the rear. As a result, the wire ends stand 21 not to the rear over the tubular frame 8 also these wires 17 are not in a separate operation be severed at their ends.

Wie Fig. 6 zeigt, liegen die Drähte 17 der Rückenfläche 16 in Höhe des die Rückseite 19 aufweisenden Teiles 22 der Querstrebe 12. Diese Drähte 17 haben gleiche Krümmung wie die Querstrebe 12, so daß am Übergang von der Querstrebe 12 zum Drahtgitter 16 kein Absatz gebildet wird. Die aufwärts verlaufenden Drähte 15 sind an der von der Rückenfläche abgewandten Rückseite der Drähte 17 vorgesehen und mit diesen verbunden.As shown in Fig. 6, the wires 17 are the back surface 16 in the amount of the part 22 having the rear side 19 the cross strut 12. These wires 17 have the same curvature like the cross strut 12, so that at the transition from the Cross strut 12 to the wire mesh 16 no paragraph formed becomes. The upward wires 15 are on the back of the wires 17 facing away from the back surface provided and connected to these.

Auch die Sitzfläche 23 (Fig. 4) wird durch ein Drahtgitter gebildet, das aus einander kreuzenden Drähten 24 und 25 besteht. Diese Drähte kreuzen einander - ebenso wie die Drähte 15 und 17 der Rückenfläche 16 - rechtwinklig. Die Drähte 24 verlaufen parallel zum vorderen Rahmenteil 6, sind also wie dieser konkav gekrümmt ausgebildet. Diese Drähte 24 erstrecken sich zwischen den einander gegenüberliegenden seitlichen Rahmenteilen 4, 5 des Rohrrahmens 3. Beide Enden 26 der Drähte 24 sind rechtwinklig nach unten abgebogen und an den einander zugewandten Innenseiten der seitlichen Rahmenteile 4, 5 befestigt. Diese Drahtenden 26 erstrecken sich wiederum nur über etwas mehr als den halben Durchmesser der seitlichen Rahmenteile 4, 5, so daß sie nicht über diese überstehen. Darum müssen diese Drahtenden 26 nicht in einem gesonderten Arbeitsgang abgetrennt werden.The seat 23 (FIG. 4) is also covered by a wire mesh formed, the crossing wires 24 and 25 exists. These wires cross each other - just like the wires 15 and 17 of the back surface 16 - rectangular. The wires 24 run parallel to the front frame part 6, so they are concavely curved like this. These wires 24 extend between each other opposite side frame parts 4, 5 of the Tubular frame 3. Both ends 26 of the wires 24 are rectangular bent down and facing each other Inside of the side frame parts 4, 5 attached. These wire ends 26 in turn extend only about a little more than half the diameter of the side Frame parts 4, 5 so that they do not have this survive. Therefore, these wire ends 26 do not have to be separated in a separate operation.

Wie Fig. 3 zeigt, liegen die Drähte 24 in Höhe der Oberseite der Rahmenteile 4, 5, so daß am Übergang von den Rahmenteilen zum Drahtgitter kein Absatz gebildet wird. Auch die Drähte 17 der Rückenfläche 16 liegen, wie Fig. 6 zeigt, in Höhe der Vorderseite der seitlichen Rahmenteile 9, 10 und des oberen Rahmenteiles 11, so daß am Übergang von der Rückenfläche 16 in die Rahmenteile 4 bis 6 ebenfalls kein Absatz gebildet wird, der beim Anlehnen als störend empfunden würde.As shown in Fig. 3, the wires 24 are at the top the frame parts 4, 5, so that at the transition from the Frame parts to the wire mesh no paragraph is formed. The wires 17 of the back surface 16 also lie, as shown in FIG. 6 shows, at the level of the front of the side frame parts 9, 10 and the upper frame part 11, so that on Transition from the back surface 16 into the frame parts 4 to 6 also no paragraph is formed, which when leaning would be perceived as disturbing.

Die Drähte 25 der Sitzfläche 23 sind an der Unterseite der Drähte 24 angeschweißt. Ihre vorderen Enden 27 sind, wie Fig. 3 zeigt, rechtwinklig nach unten abgebogen und an der dem Rückenteil 2 zugewandten Innenseite des vorderen Rahmenteiles 6 befestigt. Die Drahtenden 27 erstrecken sich wiederum nur wenig über den halben Durchmesser des Rahmenteiles 6, so daß diese Drahtenden nicht nach unten über den Rahmenteil ragen. Darum müssen die Drahtenden 27 ebenfalls nicht in einem gesonderten Arbeitsgang getrennt werden.The wires 25 of the seat 23 are on the underside the wires 24 welded. Your front ends are 27, 3 shows, bent downwards at right angles and on the inside of the front part facing the back part 2 Frame part 6 attached. The wire ends 27 extend turn just a little over half the diameter of the frame part 6, so that these wire ends are not protrude downwards over the frame part. That's why they have to Wire ends 27 also not in a separate operation be separated.

Nahe dem Übergang vom Sitzteil 1 in den Rückenteil 2 sind die seitlichen Rahmenteile 4, 5 des Sitzteils 1 durch eine Querstrebe 28 verbunden, die vorteilhaft gleich ausgebildet ist wie die Querstrebe 12 des Rückenteils 2. Die Querstrebe 28 ist mit ihren Enden an den einander zugewandten Innenseiten der Rahmenteile 4 und 5 befestigt, vorzugsweise angeschweißt. Wie Fig. 5 zeigt, ist sie an ihrer Unterseite mit einer Vertiefung 29 versehen, die sich über die gesamte Länge der Querstrebe 28 erstreckt und in die die Enden 30 der Drähte 25 ragen. Die Tiefe der Vertiefung 29 entspricht der Dicke der Drahtenden 30, die an der Rückenfläche 31 der Vertiefung 29 befestigt sind. Vorteilhaft liegen die Drahtenden 30 mit ihrer Stirnseite an einem rechtwinklig zur Rückenfläche 31 liegenden Boden 32 der Vertiefung 29 an. In Richtung auf die Sitzfläche 23 sind somit die Drahtenden 30 durch den die Rückenfläche 31 aufweisenden Teil 33 der Querstrebe 28 abgedeckt, so daß nicht die Gefahr besteht, daß die Drahtenden 30 die Kleidung beschädigen können.Near the transition from the seat part 1 to the back part 2 are the side frame parts 4, 5 of the seat part 1 connected by a cross strut 28, which is advantageous is of the same design as the cross strut 12 of the back part 2. The cross strut 28 is at the ends mutually facing inner sides of the frame parts 4 and 5 attached, preferably welded. 5 shows is provided on its underside with a recess 29, which extend over the entire length of the cross strut 28 extends and into which the ends 30 of the wires 25 protrude. The depth of the recess 29 corresponds to the thickness of the Wire ends 30 on the back surface 31 of the recess 29 are attached. The wire ends 30 are advantageously located with its face at a right angle to the back surface 31 lying bottom 32 of the recess 29. In The wire ends are thus towards the seat surface 23 30 through the part 33 having the back surface 31 the cross strut 28 covered so that there is no risk that the wire ends 30 damage the clothing can.

Die Querstrebe 28 ist in gleicher Weise wie der vordere Rahmenteil 6 und die Drähte 24 gekrümmt.The cross strut 28 is in the same way as the front Frame part 6 and the wires 24 curved.

An der Unterseite der Rahmenteil 4, 5 des Sitzteiles 1 sind zwei Winkelstücke 34 und 35 befestigt (Fig. 2), die jeweils L-förmig ausgebildet sind. Auf ihren einander zugewandten horizontalen Schenkeln 36 und 37 wird eine Querstrebe 38 befestigt, durch welche der Sitzteil 1 ausreichend versteift wird. Die Schenkel 36, 37 weisen jeweils wenigstens eine Öffnung 39, 40 auf, durch welche Schrauben, Gewindebolzen und dergleichen gesteckt werden können, um die Querstrebe 38, die mit ihren Enden auf den Schenkeln 36, 37 aufliegt, lösbar mit den Winkelstücken 34, 35 verbinden zu können. Hierzu können bügelförmige Klemmlaschen 43 und 44 verwendet werden, die die Enden der Querstrebe 38 übergreifen und an den Schenkeln 36, 37 befestigt sind.On the underside of the frame part 4, 5 of the seat part 1 are two elbows 34 and 35 attached (Fig. 2), the are each L-shaped. On their each other facing horizontal legs 36 and 37 is a Fixed cross strut 38 through which the seat part 1 is sufficiently stiffened. The legs 36, 37 have each have at least one opening 39, 40 through which Screws, threaded bolts and the like can be inserted can to the cross strut 38 with its ends on the legs 36, 37 rests, releasably with the elbows 34, 35 to be able to connect. This can be bow-shaped Clamping tabs 43 and 44 are used, the Grip ends of the cross strut 38 and on the legs 36, 37 are attached.

Die rechtwinklig zu den Schenkeln 36, 37 sich erstreckenden Schenkel 41, 42 der Winkelstücke 34, 35 sind mit ihren Stirnseiten an der Unterseite der Rahmenteile 4, 5 befestigt, vorzugsweise angeschweißt. Diese aufwärts gerichteten Schenkel 41, 42 liegen etwa in halber Breite der Rahmenteile 4, 5, so daß sie nicht stören. Wie Fig. 2 zeigt, liegt die Querstrebe 38 im Bereich unterhalb des vorderen Rahmenteiles 6 bzw. der Sitzfläche 23.Which extend at right angles to the legs 36, 37 Legs 41, 42 of the angle pieces 34, 35 are with their end faces on the underside of the frame parts 4, 5 attached, preferably welded. This upward Legs 41, 42 are approximately half the width the frame parts 4, 5 so that they do not interfere. As Fig. 2 shows, the cross strut 38 lies in the area below of the front frame part 6 or the seat 23.

Da die Sitzfläche 23 und die Rückenfläche 16 unterschiedlich gebogen sind, ergibt sich eine optimale körpergerechte Anpassung und ein hoher Sitzkomfort. Da die Rohrrahmen 3 und 8 einstückig miteinander ausgebildet sind, weist der Gesamtrahmen 3, 8 nur eine einzige Schweißstelle auf. Da die Drahtenden der die Rückenfläche 16 und die Sitzfläche 23 bildenden Drahtgitter nicht auf den Rohrrahmen 3, 8 aufliegen, ergeben sich auch herstellungstechnische Vorteile. So kann die Beschichtung der Rohrrahmen wesentlich dünner ausgebildet sein, da die Drahtenden anschließend nicht abgetrennt werden müssen. Because the seat 23 and the back surface 16 are different are bent, there is an optimal fit Adaptation and a high level of seating comfort. Since the Tubular frames 3 and 8 integrally formed with each other are, the overall frame 3, 8 has only one Weld on. Because the wire ends of the back surface 16 and the seat 23 forming wire mesh lie on the tubular frame 3, 8 also result manufacturing advantages. So the coating the tubular frame should be made much thinner, since the wire ends will not be cut off afterwards have to.

Die Drahtgitter haben rechteckige Maschen, die einen besonders hohen Sitzkomfort ergeben. Selbstverständlich können die Drahtgitter auch jede andere geeignete Struktur aufweisen. Die Winkelstücke 34, 35 können je nach Art der Unterkonstruktion unterschiedlich gestaltet sein.The wire mesh has rectangular meshes that make you special result in high seating comfort. Of course the wire mesh can also have any other suitable structure exhibit. The elbows 34, 35 can depend on The type of substructure is designed differently be.

Das beschriebene Sitzmöbel ist als Sitzschale ausgebildet, die auf einem Träger, einem Traggestell oder auch an einer Wand befestigt werden kann.The seating furniture described is designed as a seat shell, that on a carrier, a support frame or also can be attached to a wall.
