Abstract

The seat (3) is joined to a backrest (2) and a carrying rack (1). The seat can move from a seat position to a couch position via a shifting and lifting movement. A reset spring is provided, and the backrest is connected to the seat via two connection axles (8,9) in the region of the angle vertex at either side. The axles run in two longitudinal hollow slides (10,11), where the first pair (8,10) are arranged at the rear edge of the seat, reaching up to the back rest. The second pair (9,11) are arranged at a distance above the first pair and at the rear edge of the seat. The second pair is located in the middle between a pivoting axis (4) and the first pair, which is located at the same height as a top cushion of the seat.

Description

Die Erfindung betrifft ein Sitzmöbelelement o. dgl., insbesondere Polstermöbelelement, mit einer gekoppelten Rückenlehnen- und Sitzverstellung mit den Merkmalen des Oberbegriffs von Anspruch 1. Unter einem Sitzmöbelelement ist auch ein sitzfähiges Liegemöbel zu verstehen, z. B. eine Polsterliege mit hochstellbarem Rückenteil oder ein entsprechendes Krankenhausbett.The invention relates to a seating element or the like, in particular upholstered furniture element, with a coupled backrest and seat adjustment with the features of the preamble of claim 1. Under a seating element is also a seatable To understand reclining furniture, e.g. B. an upholstered lounger with a raised back section or an appropriate hospital bed.

Bekannt sind aus dem Stand der Technik unterschiedlich komfortable und unterschiedlich aufwendig konstruierte Sitzmöbelelemente (Sessel, Polstersessel, Ruhesessel, Bus-, Bahn- und Flugzeugsitze, Liegemöbel mit hochstellbarem Rückenteil), insbesondere Polstermöbelelemente, bei denen die Rückenlehnenverstellung und die Sitzverstellung gekoppelt sind. Einen guten Überblick des insgesamt bekannten Standes der Technik gibt die den Ausgangspunkt für die Lehre der vorliegenden Erfindung bildende WO 95 / 25 452.Different comfortable and different are known from the prior art elaborately designed seating elements (armchairs, upholstered armchairs, recliners, Bus, train and airplane seats, reclining furniture with a raised back section), in particular Upholstered furniture elements in which the backrest adjustment and the Seat adjustment are coupled. A good overview of the overall known The prior art provides the starting point for the teaching of the present invention forming WO 95/25452.

Bekannt ist zunächst ein Sitzmöbelelement (Fig. 1, 2 der WO 95/25 452), bei dem die Rückenlehne mit dem Sitz eine winkelsteife Einheit bildet, die am Traggestell um eine Schwenkachse unterhalb des Sitzes so schwenkbar befestigt ist, daß die Rückenlehne beim Rückkippen in die Liegestellung nach hinten und unten kippt, während der Sitz am hinteren Ende nach unten und am vorderen Rand selbstverständlich nach oben schwenkt. Das erfolgt normalerweise gegen die Kraft einer Rückstellfeder. Hier stört die winkelsteife Verbindung von Rückenlehne und Sitzverstellung, es gibt also keine gestreckte Position von Rückenlehne und Sitz. Außerdem stört es, daß der vordere Rand des Sitzes in Liegestellung erheblich nach oben bewegt wird, was den Beinen des Benutzers nicht besonders zuträglich ist.First, a seating element is known (Fig. 1, 2 of WO 95/25 452), in which the Backrest with the seat forms an angularly rigid unit, which on the support frame by one Swivel axis below the seat is pivotally attached so that the backrest when tipping back into the lying position tilts back and down while the seat at the rear end down and of course at the front edge pivots above. This is usually done against the force of a return spring. Here interferes with the angularly rigid connection of the backrest and seat adjustment, so there is no extended position of the backrest and seat. It also disturbs that the front Edge of the seat in the lying position is moved up significantly, which the Legs of the user is not particularly beneficial.

Relativ weit verbreitet ist eine Konstruktion eines Sitzmöbelelementes (Fig. 3, 4 der WO 95 / 25 452), bei der das Traggestell rahmenartig gestaltet ist. Die Rückenlehne ist am rückwärtigen Teil des rahmenartigen Traggestelles schwenkbar angelenkt mit erheblichem Abstand oberhalb eines Anlenkpunktes der Rückenlehne am hinteren Rand des Sitzes. Der hintere Rand des Sitzes wird dabei mittels der Rückenlehne am Traggestell getragen. Am vorderen Rand oder nahe dem vorderen Rand ist der Sitz in einer Verschiebeführung geführt, die nur eine leichte Aufwärtsneigung aufweist, so daß der vordere Rand des Sitzes sich beim Übergang von der Sitzstellung in die Liegestellung zwar nach vorn, jedoch nur geringfügig nach oben bewegt.A construction of a seating element (Fig. 3, 4 of the WO 95/25 452), in which the supporting frame is designed like a frame. The backrest is hinged to the rear part of the frame-like support frame with considerable distance above a point of articulation of the backrest at the rear Edge of the seat. The rear edge of the seat is by means of the backrest on Carried frame. At the front edge or near the front edge the seat is in guided a shift guide that has only a slight upward inclination, so that the front edge of the seat is in the transition from the sitting position to the lying position forward, but only slightly upwards.

Bei dem zuvor erläuterten System kann ein Benutzer sich durch Verlagern des Körpergewichts relativ leicht und ohne große Kraftaufbringung in verschiedene Stellungen zwischen der Sitzstellung und der Liegestellung bringen. Allerdings ist es zumeist erforderlich, mit einer zusätzlich Bremseinrichtung zu arbeiten, um eine bestimmte gewünschte Position auch einhalten zu können.In the system explained above, a user can change his body weight relatively easy and without great effort in different positions bring between the sitting position and the lying position. However, it is mostly required to work with an additional braking device to a certain to be able to maintain the desired position.

Ein Nachteil bei dem Sitzmöbelelement ist Folge der Schwenkverbindung der Rükkenlehne und des Sitzes etwa im Winkelscheitel der beiden Elemente. Die Verbindung beider Elemente ist zwar konstruktiv einfach, beide Elemente tragen aber regelmäßig Polsterauflagen. Die vom Benutzer benutzten Polsterflächen der Polsterauflagen liegen somit etwas oberhalb des Sitzes bzw. vor der Rückenlehne und damit etwas oberhalb bzw. vor der Schwenkachse zwischen Rükkenlehne und Sitz. Das hat zur Folge, daß beim Übergang von der Sitzstellung in die Liegestellung die Polsterauflagen sich voneinander entfernen, was den von Benutzern als sehr unangenehm empfundenen "Hemdauszieheffekt" zur Folge hat.A disadvantage of the seating element is the pivot connection of the backrest and the seat roughly at the apex of the two elements. The connection Both elements are structurally simple, but both elements wear regularly Cushions. The upholstery surfaces of the upholstery used by the user are therefore somewhat above the seat or in front of the backrest and thus somewhat above or in front of the swivel axis between the backrest and the seat has the consequence that when changing from the sitting position to the lying position, the cushion pads distance from each other, which is very uncomfortable for users perceived "shirt pull-out effect".

Ein weiteres Problem, das gleichfalls Folge der zuvor erläuterten Schwenkverbindung im Winkelscheitel ist, ist ein "Loch", das sich im Becken-/Rückenbereich beim Übergang von der Sitzstellung in die Liegestellung bildet. Dieses "Loch" stört dann, wenn es zu groß ist, da der Becken-/Lendenbereich dann in Liegestellung nicht mehr richtig unterstützt wird.Another problem, which is also the result of the previously explained pivot connection is in the apex, is a "hole" that is in the pelvic / back area at the transition from the sitting position to the lying position. This "hole" bothers when it is too large, because the pelvic / lumbar area is no longer correct when lying down is supported.

Schließlich bedarf die Anbringung des Sitzes am vorderen Rand der sorgfältigen Beachtung. damit kein zu starker Stoß in die Kniekehlen des Benutzers beim Übergang von der Sitzstellung in die Liegestellung auftritt.Finally, the attachment of the seat to the front edge requires careful attention. so that there is no excessive impact on the user's knees during the transition occurs from the sitting position to the lying position.

Im Stand der Technik ist bereits versucht worden, den "Hemdauszieheffekt" dadurch zu eliminieren, daß zwischen Rückenlehne und Sitz im Bereich des hinteren Randes bzw. unteren Randes eine Verbindungsmechanik vorgesehen ist, die die Achse der Schwenkverbindung zwischen Rückenlehne und Sitz etwa dorthin legt, wo die Oberflächen der beiden Polsterauflagen in Sitzstellung aneinanderstoßen. Das wird durch randseitig von den jeweiligen Rahmen vorspringende Laschen realisiert, die nur an ihren freien Enden miteinander schwenkbar verbunden sind (Fig. 5, 6 WO 95 /25 452).Attempts have already been made in the prior art to achieve the "shirt pull-out effect" to eliminate that between the backrest and seat in the area of the rear edge or lower edge, a connection mechanism is provided, which the axis of The swivel connection between the backrest and seat is about where the Butt the surfaces of the two upholstery pads together in the sitting position. It will realized by tabs projecting from the edge of the respective frame, which are pivotally connected to one another only at their free ends (FIGS. 5, 6 WO 95/25 452).

Bei dem Sitzmöbelelement wird ein erheblicher Vorteil gegenüber den früher bekannten Sitzmöbelelementen dadurch realisiert, daß der Anlenkpunkt der Rückenlehne am Traggestell nicht oberhalb des Anlenkpunktes der Rückenlehne am Sitz, sondern erheblich unterhalb davon vorgesehen ist. Auch dies geschieht über eine Hebelmechanik, wobei eine Kniegelenkverbindung eine zusätzliche überlagerte Neigungsbewegung der Rückenlehne realisiert. Der Sitz selbst ist mit erheblichem Abstand von dem Anlenkpunkt der Rückenlehne am Traggestell nahe seinem vorderen Rand am Traggestell schwenkbar angelenkt. Da dieser Anlenkpunkt nahe dem vorderen Rand des Sitzes liegt, hebt sich der vordere Rand des Sitzes beim Übergang von der Sitzstellung in die Liegestellung weniger stark an als bei dem aus den Stand der Technik bekannten Sitzmöbelelementen.The seating element has a significant advantage over the previously known Seating elements realized in that the articulation point of the backrest on Support frame not above the pivot point of the backrest on the seat, but considerably is provided below it. This also happens via a lever mechanism, wherein a knee joint connection an additional superimposed inclination movement the backrest realized. The seat itself is at a considerable distance from the pivot point of the backrest on the support frame near its front edge on Support frame articulated. Because this pivot point is near the front edge of the seat, the front edge of the seat rises when changing from the sitting position less in the lying position than in the state of the art known seating elements.

Eine Analyse des zuvor erläuterten, bekannten Sitzmöbelelementes hat ergeben, daß dort nach wie vor der "Hemdauszieheffekt" merkbar ist, wenn man eine hinreichend gestreckte Liegestellung erreichen will. Die in Fig. 5 und 6 der WO 95 / 25 452 dargestellte Lageänderung macht deutlich, daß nur eine relativ geringe Rückkippbewegung der Rückenlehne möglich ist, wenn man nicht doch einen vergleichsweise starken "Hemdauszieheffekt" in Kauf nehmen will. Überdies ist auch das "Loch" im Bekken-/Rückenbereich noch zu stark. Schließlich zeigt jedenfalls das Ausführungsbeispiel des zuvor erläuterten Standes der Technik (Fig. 5, 6), daß ein starkes Anheben des vorderen Randes des Sitzes erfolgt. Das mag für einen Sitz mit Fußstütze noch hinnehmbar sein, für ein Sitzmöbelelement der in Rede stehenden Art, das regelmäßig eine ausklappbare Fußstütze aufweist, kommt das nicht in Betracht.An analysis of the previously known, known seating element has shown that there the "shirt pull-out effect" is still noticeable if you have a sufficient wants to reach an extended lying position. 5 and 6 of WO 95/25452 Change in position makes it clear that only a relatively small backward movement the backrest is possible if you don't have a comparatively strong one Wants to put up with "shirt pull-out effect". In addition, there is also the "hole" in the beak / back area still too strong. Finally, the embodiment shows in any case the previously explained prior art (Fig. 5, 6) that a strong lifting the front edge of the seat. That may still be the case for a seat with a footrest be acceptable for a seating element of the type in question that regularly has a fold-out footrest, that is out of the question.

Ausgangspunkt für die Lehre der vorliegenden Erfindung ist also die zuvor an zweiter Stelle erläuterte, besonders weit verbreitete Variante eines Sitzmöbelelementes, bei der die Rückenlehne am rückwärtigen Teil des rahmenartigen Traggestelles schwenkbar angelenkt ist mit deutlichem Abstand oberhalb eines Anlenkpunktes der Rückenlehne am hinteren Rand des Sitzes.The starting point for the teaching of the present invention is therefore the second one above Spot explained, particularly widespread variant of a seating element, at which swivels the backrest on the rear part of the frame-like support frame is articulated at a clear distance above an articulation point of the backrest at the rear of the seat.

Von diesem Stand der Technik ausgehend liegt der Erfindung das Problem zugrunde, unter Beibehaltung dieses Grundprinzips, das an sich den Vorteil größter Einfachheit für sich hat, den zuvor erläuterten "Hemdauszieheffekt" möglichst gering zu machen und das "Loch" im Becken-/Rückenbereich soweit zu schließen, daß eine gute Unterstützung des Becken-/Rückenbereiches auch in Liegestellung realisiert wird.Starting from this prior art, the invention is based on the problem while maintaining this basic principle, which in itself has the advantage of greatest simplicity has to make the "shirt pull-out effect" previously explained as small as possible and to close the "hole" in the pelvis / back area so that good support the pelvis / back area is also realized in a lying position.

Die zuvor aufgezeigte Aufgabe ist bei einem Sitzmöbelelement mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The task outlined above is for a seating element with the features of the preamble of claim 1 by the features of the characterizing part solved by claim 1.

Erfinclungsgemäß ist analysiert worden, daß es in Sitzstellung einem solchen Sitzmöbelelement immanent ist, daß sich eine Person bei korrektem Sitzen mit ihrer Hüfte immer ungefähr an ein und derselben Stelle auf dem Sitz befindet. Wo diese Stelle genau liegt, hängt natürlich von verschiedenen Einflußfaktoren ab, beispielsweise von der Höhe der Polsterauflage, dem Gewicht der Person, der Körpergröße der Person und dem Körperbau - männlich oder weiblich. Im großen und ganzen kann man aber sagen, daß der Hüftdrehpunkt des Körpers eines Benutzers sich immer in einem relativ eng begrenzten Bereich oberhalb des Sitzes und vor der Rückenlehne befinden wird.According to the invention it has been analyzed that such a seating element is in the seating position It is immanent that a person sits with his hip when sitting correctly always in approximately the same place on the seat. Where exactly this place depends, of course, on various influencing factors, for example on the height of the cushion, the weight of the person, the height of the person and physique - male or female. On the whole you can say that the hip pivot point of a user's body is always in a relative narrow area is located above the seat and in front of the backrest.

Von der zuvor erläuterten Analyse ausgehend ist alsdann analysiert worden, wie man eine Längenveränderung in der Fläche der Polsterauflage an der Rückenlehne zum Hüftdrehpunkt des Benutzers beim Übergang von der Sitzstellung in die Liegestellung vermeiden kann. Diese Längenveränderung ist nämlich die Ursache für den zuvor erläuterten "Hemdauszieheffekt". Naturgemäß bleibt der Benutzer beim Übergang von der Sitzstellung in die Liegestellung auf dem Sitz sitzen, er rutscht nicht nach vorn und nicht zurück, folglich ist anzustreben, daß auch der Rücken des Benutzers auf der Oberfläche der Polsterauflage der Rückenlehne seine Lage nicht bzw. möglichst wenig verändert.On the basis of the analysis explained above, it was then analyzed how to a change in length in the surface of the cushion on the backrest Hip pivot point of the user during the transition from the sitting position to the lying position can avoid. This change in length is the cause of the previous one explained "shirt pull-out effect". The user naturally stays with the transition sit on the seat from the sitting position to the lying position, it does not slip front and not back, consequently it should be aimed at the back of the user on the surface of the upholstery of the backrest, its position is not or if possible changed little.

Außerdem soll aber die einfache Konstruktion des den Ausgangspunkt für die Erfindung bildenden Standes der Technik mit der Schwenkachse für die Rückenlehne am Traggestell (durchgehend oder durch beidseits angeordnete Achsabschnitte gebildet) nicht grundsätzlich verlassen wird.But also the simple construction of the starting point for the invention forming prior art with the pivot axis for the backrest on Support frame (continuous or formed by axial sections arranged on both sides) is not basically left.

Nach der Lehre der Erfindung wird das zuvor beschriebene wunschgemäße Ergebnis dadurch erreicht, daß die Verbindung der Rückenlehne mit dem Sitz im Bereich des Winkelscheitels nicht über ein einfaches Schwenkgelenk mit einer Verbindungsachse realisiert wird, sondern über ein Doppelgelenk. Die im kennzeichnenden Teil von Anspruch 1 beschriebene Verbindungsmechanik mit Verbindungsachsen und Langlochkulissen gewährleistet, daß sich die Rückenlehne am unteren, am Sitz angelenkten Ende beim Übergang von der Sitzstellung in die Liegestellung gegenüber dem Sitz nach vorne, zu dessen vorderem Rand hin verlagert. Die Richtung dieser Verlagerung ist der Richtung der Verlagerung entgegengerichtet, die beim Übergang von der Sitzstellung in die Liegestellung dazu führt, daß sich die Polsterauflagen voneinander entfernen. Dadurch, daß sich die Polsterauflagen aufgrund der erfindungsgemäßen Konstruktion nicht so stark wie im Stand der Technik voneinander entfernen, bewegt sich die Polsterauflage der Rückenlehne beim Übergang von der Sitzstellung in die Liegestellung oberhalb der Polsterauflage des Sitzes etwas nach vorn und oben, so daß das im Bereich von Rücken und Hüfte bislang entstehende "Loch" wesentlich geringer ist, ja so weitgehend eliminiert werden kann, wie es vom Sitzkomfort her optimal ist.According to the teaching of the invention, the previously described desired result thereby achieved that the connection of the backrest with the seat in the area of Angle crest does not have a simple swivel joint with a connecting axis is realized, but via a double joint. Those in the characterizing part of claim 1 described connection mechanism with connection axes and slot settings ensures that the backrest is articulated on the lower, seat End at the transition from the sitting position to the lying position opposite the seat to the front, shifted to its front edge. The direction of this shift is opposite to the direction of the shift when moving from the sitting position in the lying position leads to the fact that the upholstery pads are separated from each other remove. The fact that the cushion pads due to the invention Do not move structure as far apart as in the prior art the upholstery of the backrest during the transition from the sitting position to the Lying position above the upholstery of the seat slightly to the front and up, see above that the "hole" so far created in the area of the back and hips is essential is lower, can be eliminated as far as possible in terms of seating comfort is.

Die Erfindung zeichnet sich dadurch aus, daß die Konstruktion relativ einfach und preiswert aufgebaut werden kann, daß die Aufhängung wie bisher erfolgen kann, man also im Grundsatz die bislang für bekannte Sitzmöbelelemente benutzten Traggestelle weiter benutzen kann. und daß die Anlenkpunkte gut versteckt werden können.The invention is characterized in that the construction is relatively simple and can be set up inexpensively so that the suspension can be carried out as before, in principle, the support frames previously used for known seating furniture elements can continue to use. and that the pivot points are well hidden can.

Die Lehre der Erfindung kann man auf unterschiedliche Arten konstruktiv umsetzen, dazu darf auf die dem Patentanspruch 1 nachgeordneten Patentansprüche 2 ff. verwiesen werden.The teaching of the invention can be implemented constructively in different ways, in this regard, reference may be made to claims 2 ff become.

Das in der Zeichnung dargestellte, zunächst in Fig. 1 und 2 schematisch erläuterte Sitzmöbelelement o. dgl. ist im Regelfall und nach bevorzugter Ausführung ein Polstermöbelelement, insbesondere ein Polstersessel oder ein Teil einer mehrsitzigen Polstercouch. Das bedeutet aber nicht, daß das Sitzmöbelelement nicht im Grundsatz auch ohne Polsterauflagen realisiert werden kann, beispielsweise als Garten-Sitzmöbelelement aus Kunststoff oder Holz. Wie oben schon angeführt worden ist, bezieht sich die Erfindung auf Sitzmöbelelemente im allgemeinsten Verständnis, also Elemente mit Sitz- und Rückenlehne, deren Verstellungen gekoppelt sind. Folglich kann es sich um Sessel, Polstersessel, Ruhesessel, aber auch um Bus-, Bahn- und Flugzeugsitze, um Zweisitzer-Sofas oder Dreisitzer-Sofas, gegebenenfalls auch um Liegemöbel, die sitzfähig sind, beispielsweise Krankenhausbetten mit hochstellbarem Rückenteil oder entsprechende Polsterliegen handeln.That shown in the drawing, first illustrated schematically in FIGS. 1 and 2 Seating furniture element or the like is, as a rule and according to the preferred embodiment, an upholstered furniture element, especially an upholstered armchair or part of a multi-seat upholstered couch. But that does not mean that the seating element is not in principle can also be realized without upholstery, for example as a garden seating element made of plastic or wood. As mentioned above, relates the invention relates to seating furniture elements in the most general understanding, that is, elements with seat and backrest, the adjustments of which are coupled. Hence it can for armchairs, upholstered armchairs, loungers, but also for bus, train and airplane seats Two-seater sofas or three-seater sofas, possibly also around reclining furniture that is seatable are, for example, hospital beds with a raised back or act corresponding upholstered beds.

Das in Fig. 1 und 2 dargestellte Sitzmöbelelement weist eine gekoppelte Rückenlehnen- und Sitzverstellung auf. Dazu ist zu erkennen zunächst am Traggestell 1 des hier als Polstersessel ausgeführten Sitzmöbelelementes eine Rückenlehne 2 und ein Sitz 3. Die Rückenlehne 2 ist am Traggestell 1 an einer Schwenkachse 4 schwenkbar angelenkt, wobei diese Schwenkachse 4 durchgehend oder durch beidseits angeordnete Achsabschnitte gebildet sein kann, vorzugsweise durch letzteres. Die Rückenlehne 2 ist mit dem Sitz 3 im Bereich des Winkelscheitels über ein Schwenkgelenk beweglich verbunden.The seating element shown in FIGS. 1 and 2 has a coupled backrest and seat adjustment on. For this purpose, it can first be seen on the support frame 1 of the here a backrest 2 and a seat 3 designed as an upholstered armchair. The backrest 2 is articulated on the support frame 1 on a pivot axis 4, this pivot axis 4 being continuous or arranged on both sides Axis sections can be formed, preferably by the latter. The backrest 2 is movable with the seat 3 in the area of the angle apex via a swivel joint connected.

Am vorderen Rand des Sitzes 3 befindet sich unter dem Sitz 3 im Traggestell eine Quertraverse 5, die den Sitz 3 dort trägt. An der Unterseite des Sitzes 3 befindet sich im Bereich der Quertraverse 5 eine Gleitschiene 6. Genau gesagt befindet sich am vorderen Rand des Sitzes 3 im Bereich der Quertraverse 5 an jeder Seite jeweils eine Gleitschiene 6. Quertraverse 5 und Gleitschiene 6 bilden gemeinsam eine Tragmechanik für den vorderen Rand des Sitzes 3, die eine Verschiebe- und Anhebebewegung des vorderen Randes des Sitzes 3 erlaubt. Es ist darauf hinzuweisen, daß die Verschiebe- und Anhebebewegung des Sitzes 3 am vorderen Rand anstelle einer solchen Gleitverschiebeführung auch durch eine Lenkerführung realisiert werden kann, wie das aus dem Stand der Technik an sich bekannt ist. Im Grundsatz ist es auch denkbar, lediglich mit einer Tragmechanik 5,6 etwa in der Mitte unter dem Sitz 3 am Traggestell 1 zu arbeiten. Dies bietet zusätzliche gestalterische Möglichkeiten.At the front edge of the seat 3 there is a seat 3 in the support frame Crossbeam 5, which carries the seat 3 there. At the bottom of the seat 3 is in the area of the crossbeam 5 a slide rail 6 front edge of the seat 3 in the area of the cross member 5 on each side Slide rail 6. Crossbar 5 and slide rail 6 together form a support mechanism for the front edge of the seat 3, which is a sliding and lifting movement the front edge of the seat 3 allowed. It should be noted that the Moving and lifting movement of the seat 3 at the front edge instead of such Sliding shift guidance can also be realized by a handlebar guidance, as is known per se from the prior art. In principle it is too conceivable, only with a support mechanism 5.6 approximately in the middle under the seat 3 on Support frame 1 to work. This offers additional design options.

Die Rückenlehne 2 führt gegenüber dem Traggestell 1 aus der höchsten, aufgerichteten Position, der Sitzstellung, in die niedrigste, gestreckte Position, die Liegestellung, eine überlagerte Rückkipp- und Absenkbewegung aus. Das macht Fig. 1 im Vergleich mit Fig. 2 gut deutlich. Dabei führt der Sitz 3 aus der Sitzstellung in die Liegestellung synchronisiert eine nur geringfügige Bewegung, und zwar die zuvor schon erläuterte überlagerte Verschiebe- und Anhebebewegung aus. Eine Anhebebewegung des Sitzes 3 beim Übergang von der Sitzstellung in die Liegestellung hat zum Ergebnis, daß die Gewichtsverlagerung eines Benutzers beim Versuch, sich wieder in die Sitzstellung aufzurichten, dazu genutzt wird, daß der Sitz 3 durch das höhere Gewicht des Benutzers nach unten gedrückt wird und dadurch die Rückenlehne 2, gegebenenfalls unterstützt von einer Rückstellfeder, wieder aufrichtet. Ganz ohne jede Verlagerung des Sitzes 5 geht es bei dieser Art eines Sitzmöbelelementes mit gekoppelter Rückenlehnen- und Sitzverstellung nicht, das liegt auf der Hand.The backrest 2 leads to the support frame 1 from the highest, erect Position, the sitting position, in the lowest, stretched position, the lying position, a superimposed tilting and lowering movement. Fig. 1 does this in comparison with Fig. 2 clearly. The seat 3 leads from the sitting position to the lying position synchronizes a slight movement, namely the one already explained overlaid displacement and lifting movement. A lifting movement of the seat 3 in the transition from the sitting position to the lying position has the result that a user's weight shift when trying to get back into the sitting position erect, is used that the seat 3 by the higher weight of the User is pressed down and thereby the backrest 2, if necessary supported by a return spring, straightens up again. Without any relocation the seat 5 is in this type of seating element with coupled Backrest and seat adjustment is not obvious.

In den Fig. 1 und 2 ist der Hüftdrehpunkt 7 des Körpers einer sitzenden Durchschnittsperson angedeutet. Er befindet sich bei korrektem Sitzen in einer bestimmten Lage oberhalb des Sitzes 3, in Sitzstellung in einer bestimmten Position vor der Rükkenlehne 2. Wie im allgemeinen Teil der Beschreibung bereits erläutert worden ist, verschiebt sich der Hüftdrehpunkt 7 beim Übergang von der Sitzstellung in die Liegestellung gegenüber dem Sitz 3 nicht oder nur wenig. Ziel der Erfindung ist es, eine entsprechend geringe Verlagerung auch gegenüber der Rückenlehne 2 zu erreichen, um so den "Hemdauszieheffekt" zu verringern.1 and 2, the hip pivot 7 of the body of a seated average person indicated. He is in a certain position when sitting correctly Position above the seat 3, in the sitting position in a certain position in front of the backrest 2. As has already been explained in the general part of the description, the hip pivot point 7 shifts during the transition from the sitting position to the lying position compared to the seat 3 or not at all. The aim of the invention is a to achieve a correspondingly low displacement relative to the backrest 2, so as to reduce the "shirt pull-out effect".

Fig. 1 und 2 der Zeichnung zeigen ein Sitzmöbelelement des den Ausgangspunkt für die Lehre bildenden Standes der Technik. Die Grundkonzeption der dort getroffenen Anlenkung von Rückenlehne 2 und Sitz 3 soll im Grundsatz beibehalten werden. Davon ausgehend geht die Erfindung die in einem ersten Ausführungsbeispiel in den Fig. 3 und 4 dargestellten Weg. Dort ist dargestellt die Lage von Rückenlehne 2 und Sitz 3 in Sitzstellung in durchgezogenen Linien und in Liegestellung in strichpunktierten Linien. Die Verbindung der Rückenlehne 2 mit dem Sitz 3 im Bereich des Winkelscheitels hat sich wesentlich geändert. Der Vollständigkeit halber darf darauf hingewiesen werden, daß im Regelfall eine solche Verbindung auf jeder Seite von Rückenlehne 2 und Sitz 3 realisiert ist, also rechts und links von Rückenlehne 2 und Sitz 3, oder aber auch nur an einer Stelle, nämlich etwa mittig.1 and 2 of the drawing show a seating element of the starting point for the teaching of the prior art. The basic concept of those met there The articulation of the backrest 2 and seat 3 should in principle be retained. Proceeding from this, the invention is shown in a first exemplary embodiment in FIGS 3 and 4 shown way. There is shown the position of the backrest 2 and Seat 3 in the sitting position in solid lines and in the reclining position in dash-dotted lines Lines. The connection of the backrest 2 with the seat 3 in the area of Angle apex has changed significantly. For the sake of completeness, it is allowed are pointed out that as a rule such a connection on each side of Backrest 2 and seat 3 is realized, that is to the right and left of backrest 2 and Seat 3, or only in one place, namely approximately in the middle.

Die Verbindung weist zwei Verbindungsachsen 8, 9 auf, die in zwei Langlochkulissen 10, 11 laufen. Dabei ist zu erkennen, daß das erste Paar 8, 10 aus Verbindungsachse 8 und Langlochkulisse 10 am hinteren Rand des Sitzes 3 angeordnet ist und daß die Rückenlehne 2 bis hierher reicht. Weiter ist erkennbar, daß das zweite Paar 9, 11 aus Verbindungsachse 9 und Langlochkulisse 11 am hinteren Rand des Sitzes 3 mit Abstand oberhalb des ersten Paares 8, 10 angeordnet ist. Die Darstellung in Fig. 3 macht besonders deutlich, daß sich die Rückenlehne 2 beim Übergang von Sitzstellung in Liegestellung unterhalb der Schwenkachse 4 stärker nach vorn verlagert als der Sitz 3. Die daraus resultierende Relativbewegung zwischen dem unteren Rand der Rükkenlehne 2 und dem Sitz 3 wird durch das erste Paar 8, 10 aus Verbindungsachse 8 und Langlochkulisse 10 aufgenommen. Der "Hemdauszieheffekt" wird deutlich verringert, das beim Übergang in die Liegestellung auftretende "Loch" im Lendenbereich wird auf ein komfortables Maß verringert.The connection has two connection axes 8, 9, which are in two slot settings 10, 11 run. It can be seen that the first pair 8, 10 from the connecting axis 8 and slot hole 10 is arranged at the rear edge of the seat 3 and that the Backrest 2 extends up to here. It can also be seen that the second pair 9, 11 out Connection axis 9 and slot 11 at the rear edge of the seat 3 at a distance is arranged above the first pair 8, 10. The representation in Fig. 3 makes particularly clear that the backrest 2 in the transition from sitting position in Lying position below the pivot axis 4 is shifted more forward than the seat 3. The resulting relative movement between the lower edge of the backrest 2 and the seat 3 is by the first pair 8, 10 from the connecting axis 8 and slot setting 10 added. The "shirt pull-out effect" is significantly reduced, the "hole" in the lumbar region that occurs during the transition to the lying position is reduced to a comfortable level.

Das Ausführungsbeispiel zeichnet sich weiter dadurch aus, daß die Sitzstellung und die Liegestellung durch Endstellungen der Verbindungsachsen 8, 9 in den Langlochkulissen 10, 11 definiert sind.The embodiment is further characterized in that the sitting position and the lying position by the end positions of the connecting axes 8, 9 in the slot settings 10, 11 are defined.

Fig. 4 macht deutlich, daß bevorzugt eine bestimmte Lage für das zweite Paar 9, 11 besonders positive Effekte bringt. Das zweite Paar 9, 11 aus Verbindungsachse 9 und Langlochkulisse 11 ist bei diesem Ausführungsbeispiel nämlich etwa auf der Mitte des Abstandes zwischen der Schwenkachse 4 und dem ersten Paar 8, 10 angeordnet. Ist, wie dargestellt, das erste Paar 8, 10 etwa an der Unterseite des Sitzes 3 angeordnet, so empfiehlt es sich weiter, daß das zweite Paar 9, 11 etwa in Höhe der Oberseite einer Polsterauflage 12 auf dem Sitz 3 angeordnet ist.FIG. 4 makes it clear that a specific position for the second pair 9, 11 is preferred brings particularly positive effects. The second pair 9, 11 from connecting axis 9 and In this exemplary embodiment, slot opening 11 is approximately in the middle the distance between the pivot axis 4 and the first pair 8, 10 arranged. If, as shown, the first pair 8, 10 is arranged approximately on the underside of the seat 3, it is further recommended that the second pair 9, 11 approximately at the top a cushion pad 12 is arranged on the seat 3.

Man erkennt im Ausführungsbeispiel, daß die Polsterauflagen 12 auf Rückenlehne 2 und Sitz 3 etwa gleich dick sind. Fig. 4 zeigt, wie sich die Vorderseite der Polsterauflage 12 an der Rückenlehne 2 beim Übergang in die Liegestellung über das hintere Ende der Polsterauflage 12 des Sitzes 3 hinüberverlagert und so den Lendenbereich des Benutzers unterstützt.It can be seen in the exemplary embodiment that the cushion pads 12 on the backrest 2 and seat 3 are approximately the same thickness. Fig. 4 shows how the front of the cushion cover 12 on the backrest 2 when transitioning to the lying position over the rear End of the cushion pad 12 of the seat 3 and thus the lumbar region supported by the user.

Die Zuordnung von Verbindungsachsen und Langlochkulissen zu den beiden miteinander gekoppelten Teilen, nämlich Rückenlehne 2 und Sitz 3, ist im Grundsatz frei zu bestimmen. Das dargestellte Ausfürungsbeispiel zeichnet sich aber dadurch aus, daß die erste Verbindungsachse 8 an der Rückenlehne 2 und die erste Langlochkulisse 10 am Sitz angeordnet ist, während die zweite Verbindungsachse 9 am Sitz 3 und die zweite Langlochkulisse 11 an der Rückenlehne 2 angeordnet ist. Das zweite Paar 9, 11 aus Verbindungsachse 9 und Langlochkulisse 11 dient im wesentlichen der Kompensation der Relativbewegung von Rückenlehne 2 und Sitz 3 zueinander, die Folge der Verlagerung der Verbindungsachse 8 in der Langlochkulisse 10 ist.The assignment of connecting axes and slot settings to the two with each other coupled parts, namely backrest 2 and seat 3, is in principle free to determine. However, the exemplary embodiment shown is characterized by that the first connecting axis 8 on the backrest 2 and the first slot setting 10 is arranged on the seat, while the second connecting axis 9 on the seat 3 and the second slot setting 11 is arranged on the backrest 2. The second Pair 9, 11 of connecting axis 9 and slot 11 serves essentially the Compensation for the relative movement of the backrest 2 and seat 3 to each other The consequence of the displacement of the connecting axis 8 in the slot 10 is.

Das in Fig. 3 und 4 dargestellte Ausführungsbeispiel zeigt, daß hier die erste Langlochkulisse 10 gerade verläuft und etwa parallel zur Ebene des Sitzes 3 ausgerichtet ist. Dazu korrespondiert, daß die zweite Langlochkulisse 11 gerade verläuft und, vorzugsweise, in Sitzstellung etwa senkrecht zur Ebene des Sitzes 3 ausgerichtet ist. Es ist auch denkbar, die Langlochkulisse 10 geneigt zur Ebene des Sitzes 3, und zwar vom hinteren zum vorderen Ende hin ansteigend anzuordnen. Eine solche Neigungslage führt zu einer veränderten Bewegung der Rückenlehne 2 gegenüber dem Sitz 3 je nach gewünschtem Einsatzfall, aber auch abhängig von Gestaltung und Polsterung von Rückenlehne 2 und Sitz 3.The embodiment shown in Fig. 3 and 4 shows that here the first slot setting 10 runs straight and is aligned approximately parallel to the plane of the seat 3. Corresponding to this is that the second slot setting 11 runs straight and, preferably, is oriented approximately perpendicular to the plane of the seat 3 in the sitting position. It is also conceivable, the slot 10 inclined to the level of the seat 3, namely To be arranged rising from the rear to the front end. Such an inclination leads to a changed movement of the backrest 2 relative to the seat 3 depending on the desired application, but also depending on the design and upholstery of backrest 2 and seat 3.

Fig. 3 zeigt gestrichelt angedeutet am vorderen Rand des Sitzes 3 die Neigungslage der entsprechenden Gleitschiene 6, die Teil der Tragmechanik ist. Diese Neigung kann etwa 40° gegenüber dem Boden betragen, der Neigungswinkel ist so zu wählen, daß ein Benutzer die Vorderkante des Sitzes 3 beim Übergang in die Liegestellung nicht zu stark in die Kniekehlen gedrückt bekommt. Eine gewisse Anhebung dort ist angenehm, zuviel ist nicht angenehm. Die Verlagerung am vorderen Rand des Sitzes 3 folgt im übrigen weitgehend der Gestaltung des Verbindungsbereiches im Winkelscheitel.Fig. 3 shows dashed lines on the front edge of the seat 3, the inclination the corresponding slide rail 6, which is part of the support mechanism. This tendency can be about 40 ° to the ground, the angle of inclination should be chosen that a user the front edge of the seat 3 when transitioning to the lying position does not get pressed too far into the back of the knee. A little raise there is pleasant, too much is not pleasant. The shift at the front of the Seat 3 largely follows the design of the connection area in the Angle point.

Fig. 7 zeigt den Bereich des vorderen Randes des Sitzes 3 in schematischer Darstellung und dort eingezeichnet die Verlagerung eines bestimmten Punktes am vorderen Rand des Sitzes 3 beim Übergang von der Sitzstellung in die Liegestellung. Die durchgezogene Linie zeigt die Verlagerung dieses Punktes beim Ausführungsbeispiel mit gerader Langlochkulisse 10 gemäß Fig. 3, 4. Man erkennt hier ein Abknicken dieser Kurve kurz vor Erreichen der Liegestellung, aus der Praxis hat sich ergeben, daß dieser Punkt bei etwa 5° vor Erreichen der Liegestellung liegt. Dieser Effekt ist als "Abkippen" dem Benutzer auch des aus dem Stand der Technik bekannten Sitzmöbelelementes als störend bekannt.Fig. 7 shows the area of the front edge of the seat 3 in a schematic representation and drawn in there the displacement of a certain point on the front Edge of the seat 3 at the transition from the sitting position to the lying position. The solid line shows the shift of this point in the embodiment with straight slot setting 10 according to FIG. 3, 4. One can see a kinking of this here Curve shortly before reaching the lying position, practice has shown that this point is about 5 ° before reaching the lying position. This effect is as The user also "tilts" the seating element known from the prior art known as distracting.

Fig. 5 und 6 der Zeichnung zeigt nun ein Ausführungsbeispiel, bei dem der zuvor erläuterte Abkippeffekt nicht mehr oder praktisch nicht mehr auftritt. Das wird nach dem Ausführungsbeispiel in Fig. 5 und 6 dadurch erreicht, daß die erste Langlochkulisse 10 bogenförmig-konkav, und zwar nach bevorzugter Lehre und hier dargestellt kreisbogenförmig-konkav verläuft. Die Lage der bogenförmig-konkav, im dargestellten und bevorzugten Ausführungsbeispiel kreisbogenförmig-konkav gestalteten Langlochkulisse 10 ergibt sich aus der Schwenk-Schiebebewegung der Verbindungsachse 9 bezüglich der Langlochkulisse 11 und der dabei gewünschten Verlagerung der Rückenlehne 2. Versuche haben gezeigt, daß es günstig ist, die Langlochkulisse 10 nicht ganz parallel zum unteren Rand des Sitzes 3 verlaufen zu lassen, sondern, wie dargestellt, vorzusehen, daß die Langlochkulisse 10 am hinteren Ende am unteren Rand des Sitzes 3 niedriger liegt als am vorderen Ende zum vorderen Rand des Sitzes 3 hin. Das dargestellte Ausführungsbeispiel zeigt ferner, daß in der hier gewählten Konstruktion der Kreisbogenradius der kreisbogenförmig-konkaven Langlochkulisse 10 etwa dem Abstand der beiden Verbindungsachsen 8, 9 in Sitzstellung entspricht oder etwas geringer als dieser Abstand ist. Hier gibt es natürlich breite Variationsmöglichkeiten. Grundsätzlich wäre es auch denkbar, eine weitere Optimierung durch eine S-förmige Kulisse zu realisieren oder durch eine bogenförmig-konkave Kulisse in Kombination mit einer bogenförmig-konkaven Kulisse anderen Radius oder einem Teil einer gerade geführten Kulisse zu erreichen.5 and 6 of the drawing now show an embodiment in which the previously explained Tipping effect no longer occurs or practically no longer occurs. That will be after 5 and 6 achieved in that the first slot setting 10 arc-shaped concave, namely according to preferred teaching and shown here circular arc-concave. The location of the arch-concave, shown in and preferred embodiment circular arc-shaped concave Elongated slot 10 results from the pivoting-sliding movement of the connecting axis 9 with respect to the slot setting 11 and the desired shift the backrest 2. Experiments have shown that it is favorable to use the slot pattern 10 not to run completely parallel to the lower edge of the seat 3, but, as shown, to provide that the slot 10 at the rear end at the lower edge of the seat 3 is lower than at the front end to the front Edge of the seat 3. The illustrated embodiment also shows that in the Construction chosen here is the circular arc radius of the circular arc-concave Elongated slot 10 about the distance between the two connecting axes 8, 9 in the sitting position corresponds to or is slightly less than this distance. Of course there are wide ones here Variations. In principle, it would also be conceivable to carry out further optimization to be realized by an S-shaped backdrop or by an arched-concave Backdrop in combination with an arched-concave backdrop of a different radius or to reach part of a guided tour.

Fig. 7 macht deutlich, wo der besondere Vorteil der bogenförmig-konkaven Langlochkulisse 10 des Ausführungsbeispiels der Fig. 5 und 6 liegt. Die strichpunktierte Linie in Fig. 7 gibt den Verlauf des entsprechenden Punktes bei Einsatz einer bogenförmig-konkaven Langlochkulisse 10 wieder. Der "Abkippeffekt" ist hier praktisch eliminiert, eine gleichmäßige, angenehme Bewegung der Rückenlehne 2 beim Aufrichten aus der Liegestellung ist die Folge.Fig. 7 makes it clear where the particular advantage of the arc-shaped concave slot setting 10 of the embodiment of FIGS. 5 and 6. The dash-dotted Line in Fig. 7 gives the course of the corresponding point when using an arc-concave Slotted backdrop 10 again. The "tipping effect" is practical here eliminates a smooth, comfortable movement of the backrest 2 when standing up the result is the lying position.

Fig. 6 macht deutlich, daß die der Rückenlehne 2 zugeordneten Teile, insbesondere also die erste Verbindungsachse 8 und die zweite Langlochkulisse 11 in einem Rükkenlehnenbeschlag 13 zusammengefaßt sind. Dementsprechend sind die dem Sitz 3 zugeordneten Teile, insbesondere also die zweite Verbindungsachse 9 und die erste Langlochkulisse 10 in einem Sitzbeschlag 14 zusammengefaßt. Der Rückenlehnenbeschlag 13 und der Sitzbeschlag 14 sind im dargestellten Ausführungsbeispiel miteinander verbunden, bilden also ein einziges, handhabbares Bauteil, das, hier nicht dargestellt. von einem Gehäuse umschlossen sein kann. Es liegt auf der Hand, daß jeweils ein solcher Gesamtbeschlag links und rechts am Traggestell 1 angeordnet ist, wobei zweckmäßigerweise zwei spiegelsymmetrisch angeordnete Gesamtbeschläge verwendet werden. Grundsätzlich denkbar wäre auch ein mittig angeordneter einziger Gesamtbeschlag zwischen Rückenlehne 2 und Sitz 3 oder zwei einzelne Beschläge - Rückenlehnenbeschlag und Sitzbeschlag - etwa in der Mitte zwischen Rückenlehne 2 und Sitz 3.Fig. 6 makes it clear that the parts associated with the backrest 2, in particular So the first connecting axis 8 and the second slot 11 in a backrest fitting 13 are summarized. Accordingly, the seat 3 assigned parts, in particular the second connecting axis 9 and the first Slotted hole backdrop 10 combined in a seat fitting 14. The backrest fitting 13 and the seat fitting 14 are together in the illustrated embodiment connected, so form a single, manageable component that, not shown here. can be enclosed by a housing. It is obvious that each such a total fitting is arranged on the left and right of the support frame 1, wherein expediently used two mirror-symmetrically arranged overall fittings become. In principle, a single one arranged in the middle would also be conceivable Total fitting between backrest 2 and seat 3 or two individual fittings - Backrest fitting and seat fitting - approximately in the middle between the backrest 2 and seat 3.

Das Ausführungsbeispiel in Fig. zeigt im übrigen, daß auch bei dieser Konzeption die Rückenlehne 2 etwa in Höhe der Schwenkachse 4 nach hinten abgeknickt ist, was die entsprechend komfortable Liegestellung bewirkt.The embodiment in Fig. Shows, moreover, that even with this concept the backrest 2 is bent backwards approximately at the level of the pivot axis 4, what the comfortable lying position does.

Bei zweckmäßiger Bemessung der einzelenen Abstände und Radien kann man sogar die Polsterauflage 12 über Rückenlehne 2 und Sitz 3 durchgehend ausführen und die seitlichen Gesamtbeschläge darin weitgehend verstecken.If the individual distances and radii are appropriately dimensioned, you can even run the cushion pad 12 continuously over the backrest 2 and seat 3 and the largely hide side fittings in it.

Damit die Führung der Verbindungsachsen 8, 9 in den Langlochkulissen 10, 11 reibungsarm erfolgt, ist es möglich, die Langlochkulissen 10, 11 randseitig entsprechend zu gestalten, also zu verrunden, mit Gleitbeschichtungen oder Gleiteinlagen zu versehen oder anderweitig in der Oberfläche zu behandeln. Auch läßt es sich denken, daß die Verbindungsachsen 8, 9 selbst wieder als Rollen, die in den Langlochkulissen 10, 11 laufen, ausgestaltet sein können, was Reibung nochmals deutlich verringert.So that the guidance of the connecting axes 8, 9 in the slot link 10, 11 with little friction takes place, it is possible to the slot openings 10, 11 on the edge accordingly to design, i.e. to round, to provide with sliding coatings or sliding inserts or otherwise treat the surface. It is also conceivable that the connecting axles 8, 9 themselves again as rollers, which in the slot openings 10, 11 run, can be designed, which significantly reduces friction again.

Fig. 8 zeigt eine Alternativlösung eines ebenfalls zweckmäßig gestalteten, den "Hemdauszieheffekt" verringernden Sitzmöbelelementes, bei dem die zuvor erläuterten Bezugszeichen soweit wie sinnvoll mit eingetragen worden sind. Insoweit bedarf es ergänzender Erläuterungen nicht.FIG. 8 shows an alternative solution of a likewise expediently designed "shirt pull-out effect" reducing seating element, in which the reference numerals explained above as far as reasonable. In this respect, additional needs are required No explanations.

Hier ist als Alternative vorgesehen, daß die Verbindung der Rückenlehne 2 mit dem Sitz 3 im Bereich des Winkelscheitels auf jeder Seite drei Verbindungsachsen 15, 16, 17 und eine Langlochkulisse 18 aufweist, daß die erste Verbindungsachse 15 in der Langlochkulisse 18 läuft und dieses Paar 15, 18 vor dem hinteren Rand des Sitzes 3 angeordnet ist, daß die zweite Verbindungsachse 16 an der Rückenlehne 2 mit Abstand oberhalb des Paares 15, 18 angeordnet ist, daß am hinteren Rand des Sitzes 3 die dritte Verbindungsachse 17 angeordnet ist und daß die zweite Verbindungsachse 16 und die dritte Verbindungsachse 17 miteinander über einen Hilfslenker 19 verbunden sind. Die Darstellung der Sitzstellung in durchgezogenen Linien und der Liegestellung in strichpunktierten Linien läßt erkennen, was der Hilfslenker 19 hier bewirkt. Der Sitz 3 wird beim Übergang in die Liegestellung gegenüber der Rückenlehne 2 zurückgezogen, ein Teil der den "Hemdauszieheffekt" verursachenden Verlagerung der Rückenlehne 2 gegenüber dem Sitz wird dadurch also wieder rückgängig gemacht bzw. kompensiert.It is provided as an alternative here that the connection of the backrest 2 with the Seat 3 in the area of the angle apex on each side three connecting axes 15, 16, 17 and an elongated hole backdrop 18 that the first connecting axis 15 in the Slotted backdrop 18 runs and this pair 15, 18 in front of the rear edge of the seat 3rd is arranged that the second connecting axis 16 on the backrest 2 at a distance is arranged above the pair 15, 18 that at the rear edge of the seat 3rd the third connection axis 17 is arranged and that the second connection axis 16 and the third connecting axle 17 are connected to one another via an auxiliary link 19 are. The representation of the sitting position in solid lines and the lying position in dash-dotted lines shows what the auxiliary link 19 does here. The seat 3 is opposite the backrest during the transition to the lying position 2 withdrawn, part of the shift causing the "shirt pull-out" effect the backrest 2 opposite the seat is thus reversed made or compensated.

Schließlich zeigt Fig. 9 ein letztes Ausführungsbeispiel mit einer weiteren Variante, für das vorgesehen ist, daß die Verbindung der Rückenlehne 2 mit dem Sitz 3 im Bereich des Winkelscheitels auf jeder Seite über einen sich zwischen dem Ende der Rückenlehne 2 und dem Ende des Sitzes 3 erstreckenden, beidseits schwenkbar angelenkten Hilfslenker 20 realisiert ist. Dieser Hilfslenker 20 schaffte eine einem Kniegelenk ähnliche Verbindung zwischen Rückenlehne 2 und Sitz 3, die eine Pendelbewegung des Sitzes 3 beim Übergang in die Liegestellung erlaubt, was ebenfalls, wie Fig. 9 zeigt, die Verlagerung der Rückenlehne 2 gegenüber dem Sitz 3 teilweise kompensiert.Finally, FIG. 9 shows a last exemplary embodiment with a further variant, for it is provided that the connection of the backrest 2 with the seat 3 in the area of the angled apex on each side over one between the end of the backrest 2 and the end of the seat 3 extending, hinged on both sides Auxiliary link 20 is realized. This auxiliary link 20 created a similar to a knee joint Connection between the backrest 2 and seat 3, which is a pendulum movement of the Seat 3 allowed in the transition to the lying position, which also shows, as Fig. 9 shows the displacement of the backrest 2 partially compensated for the seat 3.

Eingangs des speziellen Teils der Beschreibung ist zu der Darstellung in Fig. 1 und 2 darauf hingewiesen worden, daß der vordere Rand des Sitzes 3 auf einer Quertraverse 5 mittels einer Gleitschiene 6 gelagert ist. Dargestellt ist dort eine an sich bekannte Bremseinrichtung 21, die eine definierte Bremswirkung einzustellen erlaubt. so daß man die Bewegung des Sitzmöbelelementes zwischen Sitzstellung und Liegestellung feinfühlig beeinflussen kann oder auch einzelne Positionen feststellen kann. Eine solche Bremseinrichtung 21 sollte natürlich auch bei dem Sitzmöbelelement gemäß der Erfindung realisiert sein, wozu auf den Stand der Technik verwiesen werden darf.The input of the special part of the description is to the representation in FIGS. 1 and 2 have been noted that the front edge of the seat 3 on a crossbar 5 is mounted by means of a slide rail 6. A known one is shown there Braking device 21, which allows a defined braking effect to be set. so that the movement of the seating element between the sitting position and lying position can influence sensitively or can also determine individual positions. Such a braking device 21 should of course also according to the seating element the invention can be implemented, for which reference is made to the prior art may.
