Die Schwingen beider Schwingenpaare sind einerseits an der Unterseite des Sitzteils und andererseits an einem abgewinkelten, unter den Sitzteil reichenden Schenkel eines Rückenlehnenträgers gelagert. Der Schwenkwinkel der Rückenlehne gegenüber dem Sitzteil ist im Falle des Standes der Technik eng begrenzt. In eine Liegeposition lässt sich die Rückenlehne des vorbekannten Möbels nicht überführen.In a known by DE 36 38 746 A1 furniture of this kind, the backrest over two pairs of wings, each of two equally long wings be formed pivotally hinged to a seat part. The wings of both Swingarm pairs are on the one hand on the underside of the seat part and on the other hand on an angled, reaching under the seat part of a leg Backrest support stored. The tilt angle of the backrest opposite the seat part is strictly limited in the case of the prior art. In a Lying position can not be transferred to the backrest of the previously known furniture.

Die Aufgabe der vorliegenden Erfindung besteht darin, das aus dem Stand der Technik bekannte Möbel dahingehend weiterzubilden, dass es auch als Liege verwendet werden kann.The object of the present invention is that of the prior Technique known furniture to the effect that it also as a couch can be used.

Erfindungsgemäß wird diese Aufgabe durch das Sitz- und/oder Liegemöbel nach Anspruch 1 gelöst. Demnach ist die rückenlehnenseitige Anlenkstelle einer der Schwingen des oder der Schwingenpaare bei einer aufrechten Position der Rückenlehne oberhalb des Sitzteils angeordnet. Die Rückenlehne ist mittels des oder der Schwingenpaare gegenüber dem Sitzteil zwischen wenigstens einer aufrechten und wenigstens einer Liegeposition bewegbar. Das erfindungsgemäße Möbel ist damit vielseitig einsetzbar und benutzbar. Der Vorteil vorbekannter Möbel, wonach sich die Rückenlehne beim Übergang von einer aufrechten in eine abgesenkte Position und umgekehrt entsprechend der Rückenpartie des Benutzers bewegt, bleibt bei entsprechender Konfiguration des anspruchsgemäßen Gelenkvierecks erhalten. Die Abrollbewegung des Benutzers über das Steißbein bzw. über das Hinterteil wird von der Rückenlehne nachvollzogen. Relativbewegungen zwischen der Rückenpartie des Benutzers und der Rückenlehne werden folglich auf ein Minimum reduziert bzw. gänzlich vermieden. Damit wird ein aus ergonomischen Gründen empfehlenswerter grundlegender Wechsel der von dem Benutzer des Möbels eingenommenen Körperhaltung bei optimalem Benutzungskomfort möglich. Durch entsprechende Ausgestaltung des erfindungsgemäßen Gelenkvierecks lässt sich dabei der Verstellbereich der Rückenlehne in weiten Grenzen wählen und eine Abstimmung auf den Benutzer, beispielsweise auf dessen Körpergröße, vornehmen.According to the invention, this object is achieved by the seating and / or reclining furniture solved according to claim 1. Accordingly, the backrest side articulation point one of the wings of the pair or wings in an upright position the backrest arranged above the seat part. The backrest is by means of the or the pairs of wings opposite the seat part between at least one upright and at least one lying position movable. The Furniture according to the invention is thus versatile and usable. The advantage previously known furniture, according to which the backrest in the transition from an upright in a lowered position and vice versa according to the Moves the back of the user, remains with appropriate configuration of the claimed four-bar linkage. The rolling movement of User over the tailbone or over the rump is from the backrest traced. Relative movements between the back part of the The user and the backrest are therefore reduced to a minimum or completely avoided. This will be recommended for ergonomic reasons fundamental change of the occupied by the user of the furniture Posture possible with optimum ease of use. By corresponding embodiment of the four-bar linkage according to the invention The range of adjustment of the backrest can be chosen within wide limits and a vote on the user, for example, on his body size, make.

Bevorzugte Bauarten der in Anspruch 1 beschriebenen Erfindung ergeben sich aus den abhängigen Ansprüchen 2 bis 19.Preferred types of the invention described in claim 1 arise From the dependent claims 2 to 19.

Erfindungsvarianten mit vorteilhafter Kinematik der Rückenlehne sind in den Ansprüchen 2 und 3 beschrieben.Variants of the invention with advantageous kinematics of the backrest are in the Claims 2 and 3 described.

Ausweislich Anspruch 4 verläuft die oberhalb des Sitzteils an der Rückenlehne angelenkte Schwinge an der von dem Benutzer abgewandten Seite von Sitzteil und Rückenlehne. Dadurch wird eine Beeinträchtigung des Benutzungskomforts ebenso vermieden wie eine Beeinträchtigung des Erscheinungsbildes des erfindungsgemäßen Sitz- und/oder Liegemöbels. Eine konstruktiv einfache Bauart der oberhalb des Sitzteils an der Rückenlehne angelenkten Schwinge ist Anspruch 5 zu entnehmen.As shown in claim 4, which extends above the seat part on the backrest hinged rocker on the side facing away from the user side of the seat part and backrest. This will affect the comfort of use as well as a deterioration of the appearance avoided of the sitting and / or lying furniture according to the invention. A structurally simple Design of the above the seat part hinged to the backrest swingarm is Claim 5 can be seen.

Die Erfindungsvariante nach Anspruch 6 trägt dem Umstand Rechnung, dass die Bewegung der Rückenlehne gegenüber dem Sitzteil aufgrund der erfindungsgemäßen Kinematik auch eine translatorische Komponente besitzt. Damit die Positionsänderung der Rückenlehne gegenüber dem Sitzteil nicht durch die vorzugsweise gepolsterte Rückenlehnenauflage behindert wird, ist diese bei in aufrechter Position befindlicher Rückenlehne von dem Sitzteil bzw. von der Sitzteilauflage in Richtung der Bewegbarkeit der Rückenlehne gegenüber dem Sitzteil beabstandet. Dieser Abstand sorgt für die erforderliche Bewegungsfreiheit der Rückenlehne.The variant of the invention according to claim 6 takes into account the fact that the movement of the backrest relative to the seat part due to the invention Kinematics also has a translational component. In order to the change in position of the backrest relative to the seat part not by the preferably padded back rest pad is hindered, this is at in upright position of the backrest of the seat part or of the seat part support in the direction of the mobility of the backrest relative to the seat part spaced. This distance provides the necessary freedom of movement the backrest.

Gemäß Anspruch 7 ist in weiterer Ausgestaltung der Erfindung die Rückenlehnenauflage quergeteilt und der dem Sitzteil zugewandte Auflagenteil um eine in Richtung der Teilung der Rückenlehnenauflage verlaufende Achse schwenkbar gelagert. Diese Maßnahmen erlauben zweckmäßigerweise ein selbsttätiges Ausrichten des dem Sitzteil zugewandten Auflagenteils der Rückenlehne bei deren Bewegung gegenüber dem Sitzteil. Die Achse der ausgeführten Schwenkbewegung kann auf verschiedenste Art und Weise definiert werden. Denkbar sind etwa Schwenkverbindungen mittels Achszapfen oder Filmscharnieren.According to claim 7, the backrest rest is in a further embodiment of the invention transversely divided and the seat part facing support part to a pivotable in the direction of the division of the backrest support axis stored. These measures suitably allow an automatic Aligning the seat part facing support part of the backrest at their movement relative to the seat part. The axis of the executed Swinging motion can be defined in many different ways. Are conceivable about pivotal connections by means of journals or Film hinges.

Alternativ kann die Rückenlehnen- und/oder die Sitzteilauflage elastisch ausgebildet sein. Die Auflagenelastizität gestattet dann die erforderliche Relativbewegung der Auflagenteile selbst bei einteiliger Auflage.Alternatively, the backrest and / or the seat part support can be elastic be educated. The support elasticity then allows the required Relative movement of the support parts even with one-piece support.

Eine ergonomisch günstige Entspannungshaltung, insbesondere eine entsprechende Seitenlage oder Bauchlage, kann der Benutzer dann einnehmen, wenn die Rückenlehne des erfindungsgemäßen Sitz- und/oder Liegemöbels gegenüber dem Sitzteil in eine abgesenkte Position bewegbar ist, bei deren Einnahme die Rückenlehne und der Sitzteil an der dem Benutzer zugewandten Seite im wesentlichen in einer gemeinsamen Ebene liegen (Anspruch 8). Das erfindungsgemäße Sitz- und/oder Liegemöbel kann so beispielsweise auch zum Sonnenbaden verwendet werden.An ergonomically favorable relaxation posture, especially a corresponding Lateral or prone position, the user can then take, when the backrest of the seating and / or reclining furniture according to the invention is movable relative to the seat part in a lowered position, in whose Taking the backrest and the seat part facing the user Side substantially in a common plane (claim 8). The Seating and / or reclining furniture according to the invention can for example also for Sunbathing to be used.

Aus konstruktiven Gründen empfiehlt es sich dabei, die abgesenkte Position der Rückenlehne, bei welcher diese und der Sitzteil in einer gemeinsamen Ebene liegen, zu definieren mittels wenigstens eines insbesondere an dem Sitzteil vorgesehenen Anschlages, an welchem die Rückenlehne bei Einnahme der genannten Position in Richtung ihrer Absenkung gegenüber dem Sitzteil abgestützt ist (Ansprüche 9 und 10).For constructive reasons, it is advisable, the lowered position of Backrest, in which this and the seat part in a common plane are to be defined by means of at least one in particular provided on the seat part Stop on which the backrest when taking the said position supported in the direction of their lowering relative to the seat part is (claims 9 and 10).

Im Interesse der Sicherheit des Benutzers ist im Falle der Erfindungsbauart nach Anspruch 11 vorgesehen, dass die gemeinsame Ebene von Sitzteil und abgesenkter Rückenlehne maximal horizontal ausgerichtet ist. Eine Neigung der gemeinsamen Ebene von Sitzteil und abgesenkter Rückenlehne über die Horizontale hinaus nach unten wird damit vermieden. Ein rückwärtiges Abrutschen des Benutzers von dem erfindungsgemäßen Sitz-und/oder Liegemöbel wird so verhindert.In the interest of the safety of the user is in the case of Erfindungsbauart provided according to claim 11 that the common plane of the seat part and lowered backrest is maximally aligned horizontally.

The Guide rollers 13 are height adjustable on the tabs 11. alternative are invariable leadership roles in height.

Das Untergestell 4 trägt die Einheit aus Sitzteil 2 und Rückenlehne 3. Zwei parallele Stützrohre 14 des Untergestells 4, von denen in den Figuren 1 bis 3 eines gezeigt ist, lagern dabei den Unterbau 5 des Sitzteils 2. Um eine horizontale Schwenkachse 15 ist der Sitzteil 2 bzw. die Einheit aus Sitzteil 2 und Rückenlehne 3 relativ zu dem Untergestell 4 schwenkbeweglich. In der jeweils eingenommenen Schwenkstellung wird die Einheit aus Sitzteil 2 und Rückenlehne 3 in herkömmlicher Weise über zwei Gasfedern 16 an dem Untergestell 4 abgestützt. Die Gasfedern 16 sind dabei an den Außenseiten der Sitzliege 1 angebracht und verlaufen zwischen den Stützrohren 14 des Untergestells 4 und dem Unterbau 5 des Sitzteils 2. Wie üblich sind die Gasfedern 16 mittels eines nicht gezeigten, von dem Benutzer der Sitzliege 1 zu bedienenden Handhebels betätigbar. Stützrollen 17 an den Stützrohren 14 des Untergestells 4 bilden nachfolgend im einzelnen beschriebene Anschläge für die Einheit aus Sitzteil 2 und Rückenlehne 3.The base 4 carries the unit of seat part 2 and backrest 3. Two parallel Support tubes 14 of the undercarriage 4, of which in the figures 1 to 3 a is shown, thereby store the base 5 of the seat part 2. To a horizontal Pivot axis 15 is the seat part 2 or the unit of seat part 2 and backrest 3 pivotally relative to the base frame 4. In the respectively occupied Swivel position is the unit of seat part 2 and backrest 3 in conventional Supported via two gas springs 16 to the base frame 4. The gas springs 16 are attached to the outer sides of the seat 1 and run between the support tubes 14 of the undercarriage 4 and the base 5 of the seat part 2. As usual, the gas springs 16 by means of a, not shown, of the User of the seat 1 to be operated hand lever actuated. Support rollers 17 on the support tubes 14 of the base 4 form below described in detail Stops for the unit consisting of seat part 2 and backrest 3.

Wie Figur 6 entnommen werden kann, ist die Rückenlehne 3 bzw. deren Unterbau 7 über Schwingenpaare 18, 19; 20, 21 an dem Sitzteil 2, im einzelnen an dem Unterbau 5 des Sitzteils 2, angelenkt. Die Schwingen 18, 20 besitzen dabei eine sichelförmige Außenkontur und sind wesentlich länger als die Schwingen 19, 21. Sitzteilseitigen Anlenkstellen der Schwingen 18, 20 ist das Bezugszeichen "70", sitzteilseitigen Anlenkstellen der Schwingen 19, 21 das Bezugszeichen "72" zugeordnet.As can be seen from FIG. 6, the backrest 3 or its substructure is 7 via pairs of rockers 18, 19; 20, 21 on the seat part 2, in detail on the Substructure 5 of the seat part 2, articulated. The wings 18, 20 have a Crescent-shaped outer contour and are much longer than the wings 19, 21st Seat part-side articulation points of the rockers 18, 20 is the reference numeral "70", seat part side articulation points of the rockers 19, 21 the reference numeral "72" assigned.

Die Schwingen 18, 19, 20, 21 jedes Schwingenpaares 18, 19; 20, 21 bilden mit dem Sitzteil 2 bzw. dessen Unterbau 5 als Gestell und mit der Rückenlehne 3 bzw. dessen Unterbau 7 als Koppel ein Gelenkviereck. Mittels dieser Gelenkvierecke wird die Rückenlehne 3 relativ zu dem Sitzteil 2 auf einer definierten Bahn geführt. Stufenlos lässt sich die Rückenlehne 2 dabei in die in Figur 1 gezeigte aufrechte Endstellung, die in Figur 3 gezeigte abgesenkte Endstellung und jede beliebige Zwischenstellung überführen. In einer der möglichen Zwischenstellungen, hier in einer aufrechten Position, ist die Rückenlehne 3 in Figur 2 dargestellt. In dem Zustand gemäß Figur 1 dient die Sitzliege 1 als Sitzmöbel, in dem Zustand gemäß Figur 3 als Liege.The rockers 18, 19, 20, 21 of each pair of rockers 18, 19; 20, 21 form with the seat part 2 and its base 5 as a frame and with the backrest 3 and its substructure 7 as coupling a four-bar linkage. By means of these four-bar linkages the backrest 3 is guided relative to the seat part 2 on a defined path. Steplessly, the backrest 2 can be upright in the shown in Figure 1 End position, the lowered end position shown in Figure 3 and any Transfer intermediate position. In one of the possible intermediate positions, here in an upright position, the backrest 3 is shown in Figure 2. By doing Condition according to Figure 1 is the seat 1 as seating, in the state according to Figure 3 as a couch.

Zur Fixierung der jeweils eingenommenen Position der Rückenlehne 3 dient eine Gasfeder 22, die sich einerseits an dem Unterbau 5 des Sitzteils 2 und andererseits an dem Unterbau 7 der Rückenlehne 3 abstützt. Dabei ist die Gasfeder 22 sowohl an dem Unterbau 5 des Sitzteils 2 als auch an dem Unterbau 7 der Rückenlehne 3 um eine horizontale Achse drehbar gelagert. Die Verbindung zwischen dem Unterbau 5 des Sitzteils 2 und der Gasfeder 22 wird hergestellt mittels Lageraugen an der Gasfeder 22 und in diese eingreifenden sitzteilseitigen Lagerzapfen, 23, 24, (Figur 4). Entsprechend ist die Lagerung der Gasfeder 22 an dem Unterbau 7 der Rückenlehne 3 konstruktiv gestaltet. Einem mit den betreffenden Lagerzapfen versehenen Lagerbock an dem Unterbau 7 der Rückenlehne 3 ist in den Abbildungen 5 und 6 das Bezugszeichen "25" zugeordnet.To fix the respectively assumed position of the backrest 3 serves a Gas spring 22, on the one hand to the base 5 of the seat part 2 and on the other is supported on the base 7 of the backrest 3. In this case, the gas spring 22nd both on the base 5 of the seat part 2 and on the base 7 of the Backrest 3 rotatably mounted about a horizontal axis. The connection between the substructure 5 of the seat part 2 and the gas spring 22 is manufactured by means of Bearing eyes on the gas spring 22 and in this engaging seat side bearing journals, 23, 24, (Figure 4). Accordingly, the storage of the gas spring 22 at the Substructure 7 of the backrest 3 structurally designed. One with the concerned Trunnion provided bearing block on the base 7 of the backrest 3 is in Figures 5 and 6 assigned the reference numeral "25".

Gemäß den Figuren 4 und 6 ist der Unterbau 5 des Sitzteils 2 im wesentlichen W-förmig ausgebildet. Zwischen zwei Außenschenkeln 26, 27 zur Lagerung der Sitzteilauflage 6 und einem doppelwandigen Mittelschenkel 28 ergeben sich dabei Zwischenräume 29, 30. In diesen sind die Schwingen 18, 19, 20, 21 aufgenommen. Die sitzteilseitigen Anlenkstellen 70 der sichelförmigen Schwingen 18, 20 befinden sich dabei an den Außenschenkeln 26, 27, die sitzteilseitigen Anlenkstellen 72 der "kurzen" Schwingen 19, 21 an dem Mittelschenkel 28 des Unterbaus 5. Mit ihren gegenüberliegenden Enden sind die sichelförmigen Schwingen 18,20 an der Außenseite, die Schwingen 19, 21 an der Innenseite des im Querschnitt U-förmigen Unterbaus 7 der Rückenlehne 3 angelenkt. Zur Herstellung der Verbindung zwischen den Schwingen 18, 20 und dem Unterbau 7 dient dabei eine die beiden U-Schenkel des Unterbaus 7 durchsetzende Querachse 31, welche die betreffenden Anlenkstellen definiert. Die Querachse 31 weist an ihren Enden Achsvorsprünge 32 auf, von denen in den Figuren 5 und 6 einer gezeigt ist. An dem Unterbau 5 des Sitzteils 2 sind den Achsvorsprüngen 32 Taschen 33, 34 zugeordnet, die an den Innenseiten der Außenschenkel 26, 27 des Unterbaus 5 ausgespart sind und stirnseitige Querbegrenzungen 35, 36 aufweisen (Figur 4).According to Figures 4 and 6, the base 5 of the seat part 2 is substantially W-shaped educated. Between two outer legs 26, 27 for supporting the seat part support 6 and a double-walled middle leg 28 arise here Interspaces 29, 30. In these, the wings 18, 19, 20, 21 are added. The seat part side pivot points 70 of the sickle-shaped wings 18, 20th are located on the outer legs 26, 27, the seat part side Anlenkstellen 72 of the "short" wings 19, 21 on the middle leg 28 of the Substructure 5. With their opposite ends are the crescent-shaped Swing 18,20 on the outside, the wings 19, 21 on the inside of the articulated in cross-section U-shaped base 7 of the backrest 3. to Production of the connection between the rockers 18, 20 and the substructure 7 serves one the two U-legs of the substructure 7 passing through Transverse axis 31, which defines the relevant articulation points. The transverse axis 31 has at its ends axle projections 32, of which in the figures 5 and 6 one is shown. On the substructure 5 of the seat part 2 are the Achsvorsprüngen 32nd Pockets 33, 34 associated with the inner sides of the outer legs 26, 27th of the substructure 5 are recessed and end-side transverse boundaries 35, 36th have (Figure 4).

Jedenfalls bei aufrechter Position der Rückenlehne 3 (Figuren 1, 2) sind die rückenlehnenseitigen Anlenkstellen 31 der Schwingen 18, 20 oberhalb des Sitzteils 2 angeordnet. Aufgrund ihrer Bogen- bzw. Sichelform können die Schwingen 18, 20 auf der von dem Benutzer abgewandten Seite von Sitzteil 2 und Rückenlehne 3 verlaufen. Sie sind dabei gegenüber den Längsaußenseiten des Sitzteils 2 nach innen versetzt.In any case, in the upright position of the backrest 3 (Figures 1, 2) are the backrest-side articulation points 31 of the rockers 18, 20 above the Seat part 2 arranged. Due to their bow or sickle shape, the Swing 18, 20 on the side facing away from the user side of seat part 2 and Backrest 3 run. They are opposite the longitudinal outer sides of the Seat part 2 offset inwards.

Soll die Rückenlehne 3 ausgehend von ihrer aufrechten Endstellung gemäß Figur 1 gegenüber dem Sitzteil 2 abgesenkt werden, so ist von dem Benutzer der Sitzliege 1 zunächst die Gasfeder 22 zu entriegeln. Dies geschieht durch Betätigen eines herkömmlichen, nicht im einzelnen gezeigten Handhebels. Drückt der Benutzer dann mit seinem Rücken gegen die entriegelte Rückenlehne 3 so senkt sich diese entlang einer definierten Bewegungsbahn ab. In dem in den Figuren 1 bis 3 dargestellten Beispielsfall lässt sich die Rückenlehne 3 zwischen einer annähernd vertikalen und einer annähernd horizontalen Position, d.h. über einen Winkel von rund 90 Grad verstellen.If the backrest 3, starting from its upright end position according to Figure 1 are lowered relative to the seat part 2, as is the user of the Seat 1 initially to unlock the gas spring 22. This is done by pressing a conventional, not shown in detail hand lever. Press that Then user with his back against the unlocked backrest 3 so lowers These along a defined trajectory from. In the in the figures 1 to 3 illustrated example, the backrest 3 can be between a approximately vertical and approximately horizontal position, i. over one Adjust the angle by about 90 degrees.

Aufgrund entsprechender Konfiguration der von den Schwingenpaaren 18, 19; 20, 21, dem Sitzteil 2 sowie der Rückenlehne 3 gebildeten Gelenkvierecke ist sichergestellt, dass die Rückenlehne 3 bei ihrer Bewegung relativ zu dem Sitzteil 2 eine Bewegung ausführt, welche der Bewegung der Rückenpartie des Benutzers der Sitzliege 1 entspricht. Insbesondere eine entsprechende Wahl der Anlenkstellen der Schwingen 18, 19, 20, 21 an dem Unterbau 5 des Sitzteils 2 sowie an dem Unterbau 7 der Rückenlehne 3 bewirkt, dass die Rückenlehne 3 bei ihrer Bewegung relativ zu dem Sitzteil 2 die vom Steißbein bzw. dem Hinterteil des Benutzers ausgeführte Abrollbewegung nachvollzieht. Eine Konfiguration der Gelenkvierecke, wie sie an Sitzliegen 1 für Benutzer mittlerer Größe vorgesehen sein kann, ergibt sich aus Figur 7. Due to corresponding configuration of the pairs of rockers 18, 19; 20 21, the seat part 2 and the backrest 3 formed four-bar linkages is ensured that the backrest 3 in its movement relative to the seat part 2 a Movement, which reflects the movement of the back of the user Seat 1 corresponds. In particular, a corresponding choice of articulation points the rockers 18, 19, 20, 21 on the base 5 of the seat part 2 and on the Substructure 7 of the backrest 3 causes the backrest 3 in its movement relative to the seat part 2 of the tailbone or the rear part of the user reproduced executed rolling movement. A configuration of the four-bar linkages, as they are provided on seats 1 for mid-sized users can, as can be seen in FIG. 7.

    In den Figuren 8a bis 8d sind am Beispiel der Schwingen 18, 19 die Bewegungsabläufe an den Schwingenpaaren 18, 19; 20, 21 bei Überführung der Rückenlehne 3 von einer aufrechten in eine Liegeposition veranschaulicht. Jedenfalls bei aufrechten Positionen der Rückenlehne 3, wie sie in den Figuren 8a und 8b dargestellt sind, befinden sich die rückenlehnenseitigen Anlenkstellen 31 der Schwingen 18, 20 oberhalb des Sitzteils 2. Die kurzen Schwingen 19, 21 sind während der gesamten Schwenkbewegung der Rückenlehne 3 unterhalb des Sitzteils 2 angeordnet. Sie erstrecken sich von dem rückenlehnenseitigen Ende des Sitzteils 2 zu dem unteren Ende der Rückenlehne 3 hin. Die langen Schwingen 18, 20 sind mit Abstand von dem rückenlehnenseitigen Ende des Sitzteils 2 an dieses angelenkt. Die rückenlehnenseitigen Anlenkstellen 31 der Schwingen 18, 20 beschreiben daher bei der Schwenkbewegung der Rückenlehne 3 gegenüber dem Sitzteil 2 eine Kreisbahn mit verhältnismäßig großem Radius. Die Translationskomponente der rückenlehnenseitigen Anlenkstellen 31 der Schwingen 18, 20 zu dem Sitzteil 2 hin bzw. von diesem weg ist daher relativ klein. Der Betrag dieser Translationskomponente kann über die Anordnung der sitzteilseitigen Anlenkstellen 70 bzw. die Länge der Schwingen 18,20 eingestellt werden. Entsprechend wirkt sich die Wahl der Länge der Schwingen 19, 21 aus.In the figures 8a to 8d are the movements of the example of the rockers 18, 19 on the pairs of rockers 18, 19; 20, 21 at the transfer of the backrest 3 from an upright to a reclining position illustrated. In any case, upright Positions of the backrest 3, as shown in Figures 8a and 8b are, are the backrest side articulation points 31 of the wings 18, 20 above the seat part 2. The short wings 19, 21 are during the entire pivoting movement of the backrest 3 below the seat part. 2 arranged. They extend from the backrest end of the seat part 2 towards the lower end of the backrest 3. The long wings 18, 20 are at a distance from the backrest end of the seat part 2 to this hinged. The backrest side articulation points 31 of the rockers 18, 20 describe therefore in the pivoting movement of the backrest 3 relative to the Seat part 2 a circular path with a relatively large radius. The Translation component of the backrest side articulation points 31 of Swinging 18, 20 toward and away from the seat part 2 is therefore relative small. The amount of this translation component can be determined by the arrangement of seat part-side pivot points 70 and the length of the swing 18,20 set become. Accordingly, the choice of the length of the rockers 19, 21 affects.

    Neben den Schwingen 18, 19, 20, 21 in ihrer konkreten Ausgestaltung sind in den Figuren 8a bis 8d geradlinige Verbindungen 73, 74 zwischen den sitzteilseitigen Anlenkstellen 70, 72 sowie den rückenlehnenseitigen Anlenkstellen 31, 71 der Schwingen 18, 19, 20, 21 eingezeichnet. Einfache geradlinige Hebel, die in Richtung der Verbindungslinien 73, 74 verlaufen, könnten die in dem gezeigten Beispielsfall konkret verwendeten Schwingen 18, 19, 20, 21 unter Beibehaltung der Funktionsweise der Gesamtanordnung ersetzen.In addition to the wings 18, 19, 20, 21 in their concrete embodiment are in the Figures 8a to 8d rectilinear connections 73, 74 between the seat part side Anlenkstellen 70, 72 and the backrest side articulation points 31, 71 of Swing 18, 19, 20, 21 located. Simple rectilinear lever pointing in the direction run the connecting lines 73, 74, which could in the example shown actually used swing 18, 19, 20, 21 while maintaining the Replace how the entire arrangement works.

    Mit der Schwenkbewegung der Rückenlehne 3 gegenüber dem Sitzteil 2 verbunden ist eine translatorische Relativbewegung der beiden genannten Teile der Sitzliege 1. Beim Absenken der Rückenlehne 3 beispielsweise, ausgehend von ihrer Stellung gemäß Figur 1, nähert sich daher die Rückenlehnenauflage 8 der Sitzteilauflage 6 an. Der gemäß Figur 1 zwischen der Rückenlehnenauflage 8 und der Sitzteilauflage 6 noch bestehende Spalt schließt sich. Aufgrund ihrer Schwenkbeweglichkeit kann sich dabei der Auflagenteil 9 der Rückenlehnenauflage 8 selbsttätig ausrichten. Eine Blockierung der Rückenlehnenbewegung durch sich verkeilende Auflagenteile wird dadurch vermieden.Connected to the pivotal movement of the backrest 3 relative to the seat part 2 is a translational relative movement of the two parts of the seat couch 1. When lowering the backrest 3, for example, starting from her Position according to Figure 1, therefore, approaches the backrest support 8 of the seat part support 6 on. The according to Figure 1 between the backrest support 8 and the Seat part support 6 remaining gap closes. Due to its pivoting mobility may be the support part 9 of the backrest support. 8 align automatically. A blockage of the backrest movement by itself wedging support parts is thereby avoided.

    Die Absenkbewegung der Rückenlehne 3 gegenüber dem Sitzteil 2 endet, sobald die Achsvorsprünge 32 an dem Unterbau 7 der Rückenlehne 3 in die Taschen 33, 34 an dem Unterbau 5 des Sitzteils 2 einlaufen und dort gegen die in Bewegungsrichtung liegenden und Anschläge für die Achsvorsprünge 32 bildenden Querbegrenzungen 35, 36 der Taschen 33, 34 stoßen. Aufgrund entsprechender konstruktiver Gestaltung der Gesamtanordnung laufen die Achsvorsprünge 32 in dem gezeigten Beispielsfall dann auf die Querbegrenzungen 35, 36 der Taschen 33, 34 auf, wenn der Sitzteil 2 und die Rückenlehne 3 benutzerseitig im wesentlichen in einer gemeinsamen Ebene liegen. Dass diese gemeinsame Ebene nicht über die Horizontale nach unten geneigt sein kann, wird mittels der Stützrollen 17 an dem Untergestell 4 der Sitzliege 1 erreicht. So kommen nämlich die Schwingen 18, 20 dann auf den Stützrollen 17 an dem Untergestell 4 zu liegen, wenn die mittels der Achsvorsprünge 32 und der Querbegrenzungen 35, 36 der Taschen 33, 34 definierte gemeinsame Ebene von Rückenlehne 3 und Sitzteil 2 horizontal ausgerichtet ist. Dargestellt sind die sich dabei ergebenden Verhältnisse in Figur 3.The lowering movement of the backrest 3 relative to the seat part 2 ends as soon as the axle projections 32 on the base 7 of the backrest 3 in the pockets 33, 34 run into the base 5 of the seat part 2 and there against the in the direction of movement lying and stops for the Achsvorsprünge 32 forming transverse boundaries 35, 36 of the pockets 33, 34 abut. Due to appropriate constructive Design of the overall arrangement run the axial projections 32 in the shown example case then on the transverse boundaries 35, 36 of the pockets 33, 34th on when the seat part 2 and the backrest 3 user side substantially in a common plane. That this common level does not have the Horizontal can be inclined downwards, by means of the support rollers 17 on the Underframe 4 of the seat 1 reached. This is how the wings 18, 20 come then to lie on the support rollers 17 on the base frame 4, when the means of Achsvorsprünge 32 and the transverse boundaries 35, 36 of the pockets 33, 34 defined common plane of the backrest 3 and seat part 2 aligned horizontally is. Shown are the resulting conditions in Figure 3.

    Wie aus den Figuren 1 bis 3 ebenfalls hervorgeht, folgen die Armlehnen 12 selbsttätig der Bewegung der Rückenlehne 3 gegenüber dem Sitzteil 2. Mit der Verlagerung der Rückenlehne 3 einher geht ein Schwenken der Armlehnen 12 um deren sitzteilseitige Schwenkachse. Die damit verbundene Relativbewegung der Armlehnen 12 gegenüber der Rückenlehne 3 wird mittels der rückenlehnenseitigen Führungsrollen 13 ermöglicht, die auf der Unterseite der jeweils zugeordneten Armlehne 12 abrollen.As also apparent from Figures 1 to 3, the armrests 12 follow automatically the movement of the backrest 3 relative to the seat part 2. With the relocation the backrest 3 is accompanied by a pivoting of the armrests 12 about their seat part-side pivot axis. The associated relative movement of the armrests 12 opposite the backrest 3 is by means of the backrest side Guide rollers 13 allows, on the bottom of each associated Unroll armrest 12.

    Während der Schwenkbewegung der Rückenlehne 3 sind die Gasfedern 16 verriegelt. Der Sitzteil 2 ist folglich starr mit dem Untergestell 4 verbunden. Zur Veränderung der Neigung des Sitzteils 2 sind die Gasfedern 16 zu entriegeln.During the pivotal movement of the backrest 3, the gas springs 16 locked. The seat part 2 is thus rigidly connected to the base 4. to Changing the inclination of the seat part 2, the gas springs 16 are to unlock.

    Im Falle der Sitzliege 1 gemäß den Figuren 1 bis 8d ist die maximale Neigung der Rückenlehne 3 gegen die Horizontale, d.h. diejenige Neigung der Rückenlehne 3, in welcher die Schwingen 18, 20 auf den Stützrollen 17 des Untergestells 4 aufsetzen, abhängig von der Neigung des Sitzteils 2 gegen die Horizontale. Je stärker der Sitzteil 2 gegen die Horizontale geneigt ist, desto eher laufen die Schwingen 18, 20 auf den Stützrollen 17 auf, und desto steiler ist folglich die Rückenlehne 3 in ihrer unteren Endstellung ausgerichtet. Die Stützrollen 17 bilden dementsprechend eine Vorrichtung zur Neigungsbegrenzung der Rückenlehne 3 in Abhängigkeit von der Neigung des Sitzteils 2. Auf Grund der ortsunveränderlichen Anordnung der als Anschläge für die Rückenlehne 3 wirkenden Stützrollen 17 sind verschiedenen Neigungen des Sitzteils 2 unterschiedliche Maximalneigungen der Rückenlehne 3 zugeordnet. In the case of the seat 1 according to the figures 1 to 8d, the maximum inclination of Backrest 3 against the horizontal, i. that inclination of the backrest 3, in which the rockers 18, 20 sit on the support rollers 17 of the undercarriage 4, depending on the inclination of the seat part 2 against the horizontal. The stronger the seat part 2 is inclined to the horizontal, the more likely to swing the wings 18, 20 on the support rollers 17, and therefore the steeper is the backrest. 3 aligned in its lower end position. The support rollers 17 form accordingly a device for tilt limitation of the backrest 3 in dependence from the inclination of the seat part 2. Due to the locatable arrangement the acting as stops for the backrest 3 support rollers 17 are different Slopes of the seat part 2 different maximum inclinations of Backrest 3 assigned.

    Insofern flexibler stellen sich die Verhältnisse an Sitz- und Liegemöbeln in Form von Sitzliegen 41, 61 dar, wie sie in den Figuren 9 bis 14 bzw. in Figur 15 gezeigt sind. In beiden Fällen ist nämlich mit der Neigungsverstellung des Sitzteils 2 zwangsläufig eine Lagensteuerung von Stützrollen 42, 62 verbunden.In this respect, the conditions for sitting and lying furniture become more flexible seat seats 41, 61, as shown in Figures 9 to 14 and in Figure 15 are. In both cases, namely with the tilt adjustment of the seat part 2 inevitably a layer control of support rollers 42, 62 connected.

    Bewirkt wird diese Lagensteuerung an der Sitzliege 41 mittels einer Vorrichtung 43 zur Neigungsbegrenzung der Rückenlehne 3 in Abhängigkeit von der Neigung des Sitzteils 2. Neben den bereits genannten Stützrollen 42 umfasst die Vorrichtung 43 zwei Steuerscheren 44, von denen in den Figuren 9 bis 14 die Steuerschere 44 an der dem Betrachter zugewandten Seite der Sitzliege 41 erkennbar ist. Gebildet werden die Steuerscheren 44 von Scherenarmen in Form von Schwenkarmen 45 sowie in Form von Steuerarmen 46. Dabei sind der Schwenkarm 45 sowie der Steuerarm 46 einer jeden Steuerschere 44 über ein Scherengelenk 47 miteinander verbunden. Auf den Achsen der Scherengelenke 47 sitzen die Stützrollen 42. Mit ihren von den Scherengelenken 47 abliegenden Enden sind die Schwenkarme 45 an dem Untergestell 4, die Steuerarme 46 an dem Sitzteil 2 der Sitzliege 41 angelenkt.This position control is effected on the seat couch 41 by means of a device 43 for tilt limitation of the backrest 3 in dependence on the inclination of the Seat part 2. In addition to the already mentioned support rollers 42, the device 43 includes two steering shears 44, of which in FIGS. 9 to 14 the control shears 44 the viewer facing side of the seat 41 is recognizable. Educated the control shears 44 of scissor arms in the form of pivot arms 45th and in the form of control arms 46. In this case, the pivot arm 45 and the Control arm 46 of each control scissors 44 via a scissors joint 47 with each other connected. On the axes of the scissors hinges 47 sit the support rollers 42nd With their remote from the scissor hinges 47 ends are the pivot arms 45 on the base frame 4, the control arms 46 on the seat part 2 of the seat 41st hinged.

    In den Figuren 10 bis 12 ist die Sitzliege 41 mit horizontaler Ausrichtung des Sitzteils 2 sowie mit in unterschiedlichen Positionen befindlicher Rückenlehne 3 gezeigt. Dabei nimmt die Rückenlehne 3 in Figur 12 ihre maximal geneigte Stellung ein. Die Schwingen 18, 20 sitzen auf den Stützrollen 42 auf, die folglich Anschläge für die Rückenlehne 3 bilden.In FIGS. 10 to 12, the seat cushion 41 is in the horizontal orientation of the seat part 2 and located in different positions backrest. 3 shown. In this case, the backrest 3 takes in Figure 12 their maximum inclined position one. The wings 18, 20 sit on the support rollers 42, which consequently Make stops for the backrest 3.

    Die Figuren 13 und 14 zeigen die Sitzliege 41 mit geneigtem Sitzteil 2 sowie mit zwei unterschiedlichen Stellungen der Rückenlehne 3. Maximal abgesenkt ist die Rückenlehne 3 dabei in Figur 14. Auch in diesem Fall bilden die Stützrollen 42 Anschläge für die Schwingen 18, 20 und damit gleichzeitig Anschläge für die Rückenlehne 3.Figures 13 and 14 show the seat cushion 41 with inclined seat part 2 and with two different positions of the backrest 3. Maximum is lowered Backrest 3 while in Figure 14. Also in this case, the support rollers 42 form Stops for the wings 18, 20 and thus at the same time stops for the Backrest 3.

    Wie ein Vergleich der Figuren 12 und 14 erkennen lässt, ist im Falle der Sitzliege 41 mit einer Neigung des Sitzteils 2 eine mittels Steuerscheren 44 bewirkte Absenkung der Stützrollen 42 verbunden. Daraus resultiert die Möglichkeit, die Rückenlehne 3 in beiden Fällen und ungeachtet der voneinander verschiedenen Sitzteilneigungen mit ein und demselben maximalen Neigungswinkel gegenüber der Horizontalen auszurichten.As a comparison of Figures 12 and 14 reveals is in the case of the seat 41 with an inclination of the seat part 2 caused by means of control scissors 44 Lowering the support rollers 42 connected. This results in the possibility of the Backrest 3 in both cases and regardless of each other Seat part inclinations with the same maximum angle of inclination to align the horizontal.

    Entsprechendes wird im Falle der Sitzliege 61 nach Figur 15 durch eine Vorrichtung 63 zur Neigungsbegrenzung der Rückenlehne 3 in Abhängigkeit von der Neigung des Sitzteils 2 ermöglicht.The same is in the case of the seat 61 of Figure 15 by a device 63 for tilt limitation of the backrest 3 in dependence on the inclination of the seat part 2 allows.

    Die Vorrichtung 63 umfasst dabei zwei zweiarmige Hebel 64, von denen einer an jedem der beiden Stützrohre 14 des Untergestells 4 an der Sitzliege 61 über ein Hebeldrehgelenk 65 gelagert ist.
