When the foot part (5) is extended the scissor frames (6) are blocked and only then can the operating levers of the swivel fitments be swivelled out of their basic position.

Description

Die vorliegende Erfindung betrifft ein Sitzmöbel mit einem zwischen zwei seitlichen Gestellteilen in Sitzlängsrichtung beweglich gelagerten Sitz, mit einem von zwei Aufstellscheren getragenen und geführten Fußteil und mit einer über zwei Schwenkbeschläge mit dem Sitz verbundenen und um eine im hinteren Endbereich des Sitzes liegende Achse verschwenkbaren Rückenlehne, wobei die Aufstellscheren des Fußteiles und die Schwenkbeschläge der Rückenlehne durch die Bewegung des Sitzes betätigbar sind.The present invention relates to seating with one between two lateral Frame parts movably mounted in the longitudinal direction of the seat, with one of two scissors carried and guided foot section and with one over two swivel fittings connected to the seat and around one in the rear end region of the seat lying axis swiveling backrest, with the scissors of the foot part and the swivel fittings of the backrest due to the movement of the seat are operable.

Der vorliegende Erfindung liegt die Aufgabe zugrunde, ein Sitzmöbel der gattungsgemäßen Art zu schaffen, welches sich einerseits durch die Verwendung einfacher und preiswert herstellbarer Beschläge auszeichnet und andererseits so gestaltet ist, daß eine Verschwenkung der Rückenlehne erst nach vollständigem Ausfahren des Fußteiles möglich ist.The present invention has for its object a piece of seating of the generic type Art to create, which is easier on the one hand by using and inexpensive to manufacture fittings and on the other hand is designed so that a pivoting of the backrest only after fully extending the Foot part is possible.

Diese Aufgabe wird bei einem Sitzmöbel der gattungsgemäßen Art dadurch gelöst, daß der Sitz mittels zweier Gelenkketten gegenüber den seitlichen Gestellteilen beweglich angeordnet ist, wobei der Sitzrahmen die jeweils bewegliche Koppel der Gelenkketten bildet und über jeweils eine vordere, im Anschlußbereich der Aufstellscheren liegende erste Lenkerlasche sowie über jeweils eine im Anschlußbereich der Schwenkbeschläge liegende zweite Lenkerlasche mit dem gestellseitig ortsfest festgelegten Koppelgliedern verbunden ist, daß die hinteren Lenkerlaschen im Bereich ihrer dem Sitz zugewandten Enden jeweils an einem gelenkig am Sitzrahmen angeschlossenen Hebel des jeweiligen Schwenkbeschlages angeschlossen sind, daß im vorderen Bereich der Gelenkketten an einem Scherenhebel jeder Aufstellschere der Betätigungshebel angreift, der als zweiarmiger Hebel gestellseitig oder am ortsfesten Koppelglied drehbar gelagert ist und an dessen anderem Ende ein im oberen, vorderen Gelenkpunkt jeder Gelenkkette angelenkter Steuerhebel angreift, daß die Aufstellscheren bei ausgefahrenem Fußteil blockiert sind und daß erst bei blockierten Aufstellscheren die Betätigungshebel der Schwenkbeschläge aus ihrer Grundstellung heraus verschwenkbar sind.This object is achieved in seating of the generic type in that that the seat is movable relative to the side frame parts by means of two link chains is arranged, the seat frame, the respective movable coupling of the link chains forms and via a front, in the connection area of the scissors lying first link bracket and one each in the connection area of the Second handlebar bracket lying with swivel fittings with the frame fixed on the frame side Coupling links that the rear link plates in the area their ends facing the seat each connected to an articulated on the seat frame Levers of the respective swivel fitting are connected that in front area of the link chains on a scissor lever of each set of scissors Actuating lever attacks, which acts as a two-armed lever on the frame side or on the stationary one Coupling member is rotatably mounted and at the other end in the upper, front The articulation point of each articulated chain engages the control lever that the scissors are blocked when the foot section is extended and only when blocked Set-up scissors the operating lever of the swivel fittings from their basic position are pivotable out.

Mit der vorliegenden Erfindung wird trotz der Verwendung einfach aufgebauter und insofern auch preiswert herstellbarer Beschläge eine Verschwenkung der Rückenlehne erst möglich, wenn die Aufstellscheren das Fußteil völlig ausgefahren bzw. verschwenkt haben.With the present invention, in spite of the use, it is simply constructed and insofar also inexpensive to manufacture fittings a pivoting of the backrest only possible when the scissors are fully extended or have pivoted.

Bekanntlich liegt in einer Grundstellung eines derartigen Sitzmöbels das Fußteil unterhalb des Sitzes und die Rückenlehne nimmt ihre konstruktiv vorbestimmte, steilste Stützstellung ein.As is known, in a basic position of such seating, the foot part is below of the seat and the backrest takes its constructively predetermined, steepest Support position.

Wird nun durch äußere Kräfte der Sitz aus dieser Grundstellung heraus nach hinten verschwenkt, so fährt entsprechend der durchgeführten Verschwenkbewegung das Fußteil über die Aufstellscheren in seine Gebrauchsstellung. Diese ebenfalls konstruktiv vorherbestimmbare Gebrauchsstellung wird dann beispielsweise durch einen Anschlag oder anderweitig blockiert und erst in dieser Position führt eine weitere Sitz-Verschwenkung zu einer Neigung oder Verschwenkung des Rückenteiles.If the seat is moved from this basic position backwards by external forces pivots, so moves according to the pivoting movement performed Foot part over the scissors in its use position. This is also constructive Predeterminable position of use is then, for example, by a Stop or otherwise blocked and only in this position leads to a further pivoting of the seat to tilt or swivel the back section.

Diese Neigung kann bis zu einer Strecklage reichen, so daß aus dem Sitzmöbel ein Liegemöbel geworden ist. Bewegt sich der Sitz durch Gewichtsverlagerung oder andere äußere Kräfte wieder zurück in Richtung seiner Grundstellung, wird zunächst die Rückenlehne in ihre Grundposition zurückbewegt und erst dann wird das Fußteil über die Aufstellscheren in seine Nichtgebrauchsstellung zurückgeschwenkt.This inclination can extend to a stretched position, so that from the seating Lounger furniture has become. The seat moves due to weight shift or others external forces back towards its basic position, will initially the backrest moves back to its basic position and only then does the footrest pivoted back over the scissors into its non-use position.

Die Rückenlehne 4 ist mit dem Sitz 3 über Schwenkbeschläge 7 verbunden und gegenüber dem Sitz 3 um eine im hinteren Endbereich des Sitzes 3 liegende Achse 8 verschwenkbar.The backrest 4 is connected to the seat 3 via pivot fittings 7 and opposite the seat 3 about an axis 8 lying in the rear end region of the seat 3 pivotable.

In den Figuren 2 und 3 sind aus Gründen der Übersichtlichkeit vom Sitz 3l lediglich noch der Sitzrahmen 9 und von der Rückenlehne 4 nur noch das Gestell 10 dargestellt. For reasons of clarity, FIGS. 2 and 3 only show the seat 3l nor the seat frame 9 and only the frame 10 from the backrest 4.

Wie die Figuren 2 und 3 deutlich machen, ist der Sitzrahmen 9 (und damit natürlich auch beim kompletten Sitzmöbel 1 der Sitz 3) mittels zweier Gelenkketten 11 gegenüber den seitlichen und als ortsfest zu bezeichnenden Gestellteilen 2 beweglich angeordnet. Dabei bildet der Sitzrahmen 9 die bewegliche Koppel der jeweiligen Gelenkkette 11 und im vorderen Endbereich ist der Sitzrahmen 9 über eine erste Lenkerlasche 12 an einem gestellseitig ortsfest festgelegten Koppelglied 13 angeschlossen. In seinem hinteren Endbereich ist der Sitzrahmen 9 über weitere Lenkerlaschen 14 mit den ortsfesten Koppelgliedern 13 verbunden, wobei die hinteren Lenkerlaschen 14 im Bereich ihrer dem Sitzrahmen 9 zugewandten Enden an einem gelenkig am Sitzrahmen 9 angeschlossenen Hebel 15 angelenkt sind, wobei der jeweilige Hebel 15 Bestandteil eines Schwenkbeschlages 7 zur Verschwenkung der Rückenlehne gegenüber dem Sitz ist.As FIGS. 2 and 3 make clear, the seat frame 9 (and thus, of course also in the case of complete seating furniture 1, the seat 3) by means of two articulated chains 11 opposite the lateral and to be referred to as stationary frame parts 2 movably arranged. The seat frame 9 forms the movable coupling of the respective link chain 11 and in the front end region, the seat frame 9 is over a first one Handlebar bracket 12 connected to a fixed coupling member 13 on the frame side. In its rear end region, the seat frame 9 is over further handlebar brackets 14 connected to the fixed coupling links 13, the rear Handlebar brackets 14 in the region of their ends facing the seat frame 9 on one are articulated to the seat frame 9 connected lever 15, the respective Lever 15 part of a pivot fitting 7 for pivoting the Backrest is opposite the seat.

Im vorderen Bereich der Gelenkketten 11 greift an einem Scherenhebel 16 der Aufstellscheren 6 ein Betätigungshebel 17 an, der als zweiarmiger Hebel ausgebildet und gestellseitig oder am ortsfesten Koppelglied 13 um einen Drehpunkt 18 drehbar gelagert ist. Am anderen Ende jedes Betätigungshebels 17 greift ein Steuerhebel 19 an, der mit seinem anderen Ende im oberen, vorderen Gelenkpunkt 20 der Gelenkketten 11 angeschlossen ist.In the front area of the articulated chains 11, the scissors-type lever engages with a scissor lever 16 6 an actuating lever 17, which is designed as a two-armed lever and rotatable about a fulcrum 18 on the frame side or on the stationary coupling member 13 is stored. At the other end of each operating lever 17, a control lever 19 engages at the other end in the upper, front hinge point 20 of the link chains 11 is connected.

In Figur 2 ist der Sitzbereich nebst Fußteil 5 und Rückenlehne 4 in seiner Grundstellung (= Sitzstellung) gezeigt. In Figur 3 ist eine Situation dargestellt, in der das Fußteil 5 in seine vollständige Gebrauchslage ausgeschwenkt und die Rückenlehne teilweise gegenüber dem Sitz verschwenkt ist.In Figure 2, the seating area along with foot section 5 and backrest 4 is in its Basic position (= sitting position) shown. FIG. 3 shows a situation in which the foot part 5 swung out into its full position of use and the backrest is partially pivoted relative to the seat.

Die beiden Figuren 2 und 3 machen deutlich, daß bei einer Verschwenkung des Sitzes aus der Grundstellung gemäß Figur 2 zunächst nur die Aufstellscheren 6 das Fußteil 5 in seine Gebrauchslage herausschwenken. In der ausgeschwenkten Stellung gemäß Figur 3 wird dann durch eine Blockierung der Aufstellscheren bewirkt, daß eine weitere Verschwenkung des Sitzes zu einer Verschwenkung der Rückenlehne führt. Der Hebel 15 der Schwenkbeschläge 7 wird in seiner Grundstellung gemäß Figur 2 solange fixiert, bis die Aufstellscheren 6 vollständig ausgeschwenkt und blockiert sind. Eine weitere Verschwenkung des Sitzes nach hinten führt dann zu einer Betätigung der Hebel 15 und damit zu einer Verschwenkung der Rückenlehne 3 um den Drehpunkt 8.The two Figures 2 and 3 make it clear that when the Seat from the basic position shown in Figure 2 initially only the scissors 6 the Swing the foot section 5 out into its position of use. In the swung out Position according to Figure 3 is then effected by blocking the scissors, that a further pivoting of the seat to pivot the Backrest leads. The lever 15 of the pivot fittings 7 is in his Basic position according to Figure 2 fixed until the scissors 6 completely are swung out and blocked. Another swiveling of the seat after rear then leads to an actuation of the lever 15 and thus to a pivoting the backrest 3 about the pivot point 8.

Die Ausführungsbeispiele nach den Figuren 4-6 zeigen eine Variante, bei der unterhalb des Sitzes 3 gestellseitig ein Antriebsmotor 21 angeschlossen ist, der mit einer linear aus- und einfahrbaren Antriebsspindel 22 ausgestattet ist. Diese Antriebsspindel 22 greift an einem Ende eines drehbar gelagerten, zweiarmigen Hebelarmes 23 an, der andererseits mit den Schwenkbeschlägen 7 für die Rückenlehne 3 verbunden ist.The exemplary embodiments according to FIGS. 4-6 show a variant in which below of the seat 3 on the frame side, a drive motor 21 is connected, with a linearly extendable and retractable drive spindle 22 is equipped. This drive spindle 22 engages at one end of a rotatably mounted, two-armed lever arm 23 on the other hand connected to the swivel fittings 7 for the backrest 3 is.

Aufbau und Wirkungsweise der gesamten Konstruktion gemäß den Ausführungsbeispielen nach den Figuren 4-6 entspricht dem Ausführungsbeispiel nach den Figuren 1-3, d. h., daß bei der Variante gemäß den Figuren 4-6 die Bewegung des Sitzes 3 und damit die Verschwenkung des Fußteiles 5 sowie die Verschwenkung des Rückenteiles 3 durch die Betätigung des Antriebsmotors 21 erfolgt.Structure and mode of operation of the entire construction according to the exemplary embodiments 4-6 corresponds to the embodiment of the figures 1-3, d. that is, in the variant according to FIGS. 4-6, the movement of the seat 3 and thus the pivoting of the foot part 5 and the pivoting of the Back part 3 is carried out by actuating the drive motor 21.

Die Aufstellscheren für das Fußteil 5 sind so konzipiert, daß dieses Fußteil 5 bei in Nichtgebrauchsstellung eingeschwenkter Position parallel unterhalb des Sitzes 3 liegt. Dies geht aus den Figuren 2 und 5 deutlich hervor.The scissors for the foot part 5 are designed so that this foot part 5 at in Non-use position, swiveled-in position parallel below the seat 3 lies. This is clear from Figures 2 and 5.
