Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft einen Lehnstuhl gemäss Oberbegriff des Anspruchs 1.The invention relates to a reclining chair according to the preamble of claim 1.

Stand der TechnikState of the art

Aus dem Stand der Technik sind Lehnstühle bekannt, deren Rückenlehne aus einer Sitzposition in eine Ruheposition überführbar sind. Die dafür vorgesehene Mechanik ist zumeist sehr aufwendig gestaltet und dementsprechend teuer in der Herstellung.Armchairs are known from the prior art, the backrest can be transferred from a sitting position to a rest position. The mechanism provided for this is usually designed very expensive and therefore expensive to manufacture.

In der US 101,628 ist ein Klappstuhl beschrieben. Die Rückenlehne und der Stützfuss des Klappstuhls sind an einem Drehpunkt drehbar miteinander verbunden. Die Sitzfläche hält die Rückenlehne und Stützfuss in unterschiedlichen Abständen zusammen. Dazu rastet ein an der Rückenlehne angeordneter Stift in unterschiedlichen Einbuchtungen der Sitzfläche ein. Zur Verstellung des Klappstuhls muss der Benutzer sich aus dem Klappstuhl erheben und den Stift in eine andere Einbuchtung einrasten.In the US 101,628 is a folding chair described. The backrest and the support leg of the folding chair are rotatably connected together at a pivot point. The seat holds the backrest and support leg together at different distances. For this purpose, a arranged on the backrest pin engages in different indentations of the seat. To adjust the folding chair, the user must rise from the folding chair and lock the pin into another recess.

Bei dem in der EP 1256293 beschriebenen Bürostuhl ist die Rückenlehne über einen Lehnenträger an einem Sitzträger angelehkt. Synchron hierzu ist die Sitzfläche des Bürostuhls bewegbar. Der vordere Bereich der Sitzfläche ist über eine Schiebeführung und der hintere Bereich der Sitzfläche ist über einen Sitzlenker mit dem Sitzträger verbunden. Zur Synchronisation zwischen der Bewegung der Rückenlehne und der Bewegung der Sitzfläche ist eine Schiebeführung der Sitzfläche im Lehnenträger vorgesehen. Eine Arretierung in verschiedenen Lehnen- bzw. Sitzflächenpositionen ist bei diesem Bürostuhl nicht beschrieben.In the in the EP 1256293 office chair described the backrest is articulated on a backrest support to a seat support. Synchronously, the seat of the office chair is movable. The front portion of the seat is a sliding guide and the rear portion of the seat is connected via a seat link to the seat support. For synchronization between the movement of the backrest and the movement of the seat a sliding guide of the seat is provided in the backrest support. A lock in various Lehnen- or Sitzflächenpositionen is not described in this office chair.

Aufgabe der ErfindungObject of the invention

Aufgabe der vorliegenden Erfindung ist es daher einen Lehnstuhl vorzuschlagen, welcher durch eine einfache Mechanik eine komfortable Verstellung der Rückenlehne ermöglichst.Object of the present invention is therefore to propose an armchair, which allows a simple adjustment of the backrest by a simple mechanism.

Beschreibungdescription

Erfindungsgemäss wird die Aufgabe bei einer Vorrichtung gemäss Anspruch 1 dadurch gelöst, dass das zweite Ende der Sitzfläche am ersten Tragelement verstellbar gehalten ist. Das Verstellen des zweiten Endes der Sitzfläche entlang des ersten Tragelements ermöglicht, das der Winkel, welchen die beiden Tragelemente einschliessen verstellbar ist. Diese Verstellbarkeit bewirkt, dass die Neigung der Rückenlehne verstellbar ist, welche an dem ersten Tragelement festgelegt ist. Die Verstellbare Halterung kann durch ein Einrasten der Sitzfläche in verschiedenen Rasterungen an dem ersten Tragelement erfolgen oder durch stufenlose Führung der Sitzfläche entlang einer an dem ersten Tragelement angeordneten Schiene. Denkbar wäre auch, dass die Schiene an der Sitzfläche angeordnet ist.According to the invention the object is achieved in a device according to claim 1, characterized in that the second end of the seat is adjustably held on the first support member. The adjustment of the second end of the seat along the first support member allows the angle which the two support members include adjustable. This adjustability causes the inclination of the backrest is adjustable, which is fixed to the first support member. The adjustable holder can be effected by a latching of the seat in different grids on the first support member or by stepless guidance of the seat along a rail arranged on the first support member. It would also be conceivable that the rail is arranged on the seat.

In einer besonders bevorzugten Ausführungsform ist das zweite Ende der Sitzfläche entlang einer Führungsbahn stufenlos verschiebbar am ersten Tragelement angeordnet. Diese Umsetzung der Verschiebbarkeit hat den Vorteil, dass die Rückenlehne stufenlos einstellbar ist und die gewünschte Lehnenposition genau einstellbar ist. Die Führungsbahn ist bevorzugt linear kann jedoch auch gekrümmt ausgeführt sein, um eine spezielle Position der Sitzfläche zur Rückenlehne in jeder Lehnenposition zu ermöglichen. Die Lehnenposition ist durch zwei Endposition begrenzt. Einerseits eine Position, in der die Rückenlehne ganz aufgestellt ist und andererseits eine Position in der die Rückenlehne möglichst flach eingestellt ist. Die Endpositionen werden durch die Länge der Führungsbahn bestimmt.In a particularly preferred embodiment, the second end of the seat along a guide rail is arranged continuously displaceable on the first support member. This implementation of the displaceability has the advantage that the backrest is infinitely adjustable and the desired backrest position is precisely adjustable. The guideway is preferably linear but may also be curved to allow a specific position of the seat to the backrest in each backrest position. The backrest position is limited by two end positions. On the one hand a position in which the backrest is completely set up and on the other hand, a position in which the backrest is set as flat as possible. The end positions are determined by the length of the guideway.

Zweckmässigerweise ist das zweite Ende der Sitzfläche durch wenigstens eine Führungsstrebe gebildet, welche in einer linearen Führungskulisse an dem ersten Tragelement geführt ist. Die Führungsstrebe ist schmal ausgebildet und kann an der Rückenlehne seitlich vorbeigeführt werden. Dadurch behindern sich Sitzfläche und Rückenlehne an ihrem Übergang während der Rückenlehnenverstellung nicht. Bevorzugt sind zwei Führungsstreben, welche links und rechts an der Rückenlehne vorbeiführen, um eine symmetrische Halterung der Sitzfläche zu ermöglichen.Conveniently, the second end of the seat is formed by at least one guide strut, which is guided in a linear guide slot on the first support member. The guide strut is narrow and can be guided past the backrest laterally. As a result, the seat and backrest do not obstruct at their transition during the backrest adjustment. Preference is given to two guide struts, which lead past the left and right of the backrest to allow a symmetrical mounting of the seat.

In einer weiteren bevorzugten Ausführungsform sind das erste und zweite Tragelement durch ein arretierbares Verstellelement relativ zueinander feststellbar. Das Verstellelement ermöglicht, dass keine weiteren Halte- oder Rastvorrichtungen vorhanden sein müssen, um die beiden Trageelemente aneinander zu halten. Das Verstellelement übernimmt daher die Aufgabe den Winkel der beiden Tragelemente relativ zueinander zu verstellen und nach der Verstellung die beiden Tragelemente in dieser Position zu halten.In a further preferred embodiment, the first and second support element can be fixed relative to one another by a lockable adjusting element. The adjustment allows that no other holding or locking devices must be present to hold the two support elements together. The adjusting element therefore assumes the task of the angle of the two support elements relative to each other to adjust and to hold after adjusting the two support elements in this position.

Als vorteilhaft erweist es sich, wenn das Verstellelement durch einen Seilzug arretierbar ist. Dadurch kann das Verstellelement fernbedient werden, ohne dass sich der Benutzer aus dem Lehnstuhl erheben muss.It proves to be advantageous if the adjusting element can be locked by a cable. As a result, the adjustment can be operated remotely, without the user must rise from the armchair.

Zweckmässigerweise ist der Seilzug mit einem Stellhebel verbunden, damit der Benutzer den Seilzug einfach betätigen kann. Der Stellhebel besitzt eine Haltevorrichtung, um diesen an dem Lehnstuhl befestigen zu können und damit der Stellhebel während der Betätigung gegenüber dem Lehnstuhl abgestützt ist.Conveniently, the cable is connected to a lever so that the user can easily operate the cable. The lever has a holding device to attach it to the armchair and so that the lever is supported during operation relative to the armchair.

Es versteht sich, dass es vorteilhaft ist, wenn der Stellhebel in Griffweite eines Benutzers an dem Lehnstuhl angeordnet ist, um das Verstellhebel aus der Sitz- bzw. der Liegeposition heraus bedienbar zu machen.It is understood that it is advantageous if the adjusting lever is arranged within the reach of a user on the armchair in order to make the adjusting lever operable out of the sitting or lying position.

Erfindungsgemäss ist das Verstellelement eine Gasdruckfeder, eine optional motorisch angetriebene Spindel oder eine Spiralfeder. Von Vorteil ist es, wenn die Stellkraft des Verstellelements unabhängig von seiner Länge ist. Gasdruckfedern erfüllen diese Anforderung, sind zuverlässig und günstig und sind deshalb das bevorzugte Stellelement.According to the invention, the adjusting element is a gas spring, an optionally motor-driven spindle or a spiral spring. It is advantageous if the actuating force of the adjusting element is independent of its length. Gas springs fulfill this requirement, are reliable and cheap and are therefore the preferred actuator.

Der Lehnstuhl umfasst mit Vorteil Armlehnen, welche mit ihren ersten Enden gelenkig an der Sitzfläche und mit ihren zweiten Enden gelenkig an dem ersten Tragelement angeordnet sind. Die Gelenke ermöglichen es, dass die Armlehnen die Herstellbarkeit der Rückenlehne nicht beeinträchtigen.The armchair advantageously comprises armrests, which are arranged with their first ends hinged to the seat surface and with their second ends hinged to the first support member. The joints make it possible that the armrests do not affect the manufacturability of the backrest.

In einem weiteren bevorzugten Ausführungsbeispiel umfaßt das zweite Tragelement an seinem von der Sitzfläche abgewandten Ende einen Wippfortsatz. Der Wippfortsatz lässt sich als eine Art von Kufen beschreiben, welche eine Verlängerung des ersten Tragelements sind. Die Kufen sind dabei nach innen in Richtung der Rückenlehne abgewinkelt. Verlagert der Benutzer in der Position, in der die Rückenlehne ganz nach unten verstellt ist, nach hinten so kommt der Lehnstuhl auf den Kufen zu liegen und das vordere Ende des zweiten Tragelements wird angehoben. Der Lehnstuhl kann so als eine Art Schaukelstuhl abgesehen werden, da er sich auf den Wippfortsatz nach vorne und hinten wippen lässt.In a further preferred embodiment, the second support element comprises at its end facing away from the seat end a Wippfortsatz. The Wippfortsatz can be described as a kind of runners, which are an extension of the first support member. The runners are angled inwards in the direction of the backrest. If the user moves backwards in the position in which the backrest is moved downwards, the armchair comes to rest on the runners and the front end of the second support element is raised. The armchair can be considered as a kind of rocking chair, as it can be tilted forward and back on the rocker extension.

Zweckmässigerweise ist an dem von Rückenlehne abgewandten Ende des ersten Tragelements wenigstens eine Rolle angeordnet. Dadurch lässt sich das Scherenelement besonders einfach zusammen- und auseinanderbewegen, da an dem ersten Tragelement nur ein Rollwiderstand und kein Reibwiderstand anliegt. Auch schont die Rolle den Untergrund, auf dem der erfindungsgemässe Lehnstuhls steht.Expediently, at least one roller is arranged on the end of the first support element facing away from the backrest. As a result, the scissor element is particularly easy to move together and apart, as applied to the first support member only a rolling resistance and no frictional resistance. Also protects the role of the ground on which the inventive armchair stands.

Dadurch, dass das erste Tragelement im Bereich seines Endes, welches der Rückenlehne zugewandt ist, vorteilhaft abgewinkelt ist, entsteht ein ergonomischer für den Benutzer angenehmer Übergang zwischen Sitzfläche und Rückenlehne.Characterized in that the first support member in the region of its end, which faces the backrest, is advantageously angled, creates an ergonomic for the user pleasant transition between the seat and backrest.

In einem weiteren bevorzugten Ausführungsbeispiel ist das erste und zweite Tragelement jeweils durch ein Paar von Haltestreben gebildet ist, welche ihrerseits durch Querstreben voneinander beabstandet sind. Dadurch entsteht eine stabile und einfach aufgebaute Scherenmechanik in Gestalt einer Leiterkonstruktion.In a further preferred embodiment, the first and second support member is formed in each case by a pair of retaining struts, which in turn are spaced apart by transverse struts. This results in a stable and simply constructed scissors mechanism in the form of a ladder design.

Zweckmässigerweise sind die Haltestreben und Querstreben aus Holz hergestellt, da dieser Werkstoff im Möbelbaubereich bevorzugt ist und den für den erfindungsgemässen Lehnstuhl notwendige Festigkeit und Stabilität aufweist.Conveniently, the support struts and cross struts are made of wood, since this material is preferred in the furniture industry and has the necessary strength and stability for the inventive armchair.

Erfindungsgemäss ist das Verstellelement während der Gewichtsbelastung hervorgerufen durch einen Benutzer des Lehnstuhls verstellbar. Diese Eigenschaft ist für den Benutzer besonders komfortabel, da er die Sitz- bzw. Lehnenposition verstellen kann, ohne sich aus dem Lehnstuhl erheben zu müssen.According to the invention, the adjustment is caused during the weight load caused by a user of the armchair adjustable. This feature is particularly convenient for the user, as he can adjust the seat or backrest position without having to rise from the armchair.

Als vorteilhaft erweist es sich, wenn die Sitzfläche auf einem Halterahmen angeordnet ist, welcher Halterahmen die wenigstens eine Führungsstrebe umfasst. Da die Sitzfläche in der voll aufgestellten Lehnenposition nahezu das gesamte Körpergewicht des Benutzers zu fragen hat, ist die Sitzfläche aus Stabilitätsgründen durch einen Halterahmen verstärkt. Insbesondere die wenigstens eine Führungsstrebe ist stark belastet, da grosse Hebelkräfte auf sie wirken. Deshalb ist die Führungsstrebe als Teil des Halterahmens ausgebildet und der Halterahmen vorteilhaft aus Metall gefertigt.It proves to be advantageous if the seat is arranged on a holding frame, which holding frame comprises at least one guide strut. Since the seat in the fully established backrest position has to ask almost the entire body weight of the user, the seat is reinforced for stability reasons by a support frame. In particular, the at least one guide strut is heavily loaded, since large leverage forces act on it. Therefore, the guide strut is formed as part of the holding frame and the holding frame advantageously made of metal.

Die Erfindung betrifft einen Lehnstuhl, welcher gesamthaft mit dem Bezugszeichen 11 bezeichnet ist. Der Lehnstuhl 11. umfasst ein Traggestell an welchem eine Sitzfläche 13 und eine Rückenlehne 15 gehalten ist. Das Traggestell ist in Gestalt einer Scherenmechanik 17 ausgebildet. Die Scherenmechanik 17 umfasst ein erstes und zweites Tragelement 19,21, welche ähnlich wie bei einem Liegestuhl funktionieren. Dazu sind das erste und das zweite Tragelement 19,21 kreuzförmig aneinander angeordnet und um einen Drehpunkt 23 aneinander gelenkig gehalten. Dazu sind Beschläge 25 vorgesehen, welche beispielsweise an dem ersten Trageelement 19 befestigt sind und einen ersten Zapfen 27 aufweisen, welcher in das zweite Tragelement 21 ragt (Figur 5). Sowohl das erste Tragelement 19 als auch das zweite Tragelement 19 besitzen erste Enden 29,31 und zweite Enden 33,35. Bevorzugt sind das erste und zweite Tragelement 19,21 jeweils durch ein Paar von ersten und zweiten Haltestreben 19a,19b bzw. 21a,21b gebildet. Die Haltestreben 19a,19b bzw. 21a,21b sind jeweils durch Querstreben 37 miteinander verbunden bzw. voneinander beabstandet. Im Bereich des zweiten Endes 33 des ersten Tragelements 19 ist letztgenanntes bevorzugt gekrümmt, damit ein abgerundeter (rückenschonender) Übergang zwischen Sitzfläche 13 und Rückenlehne 15 ermöglicht ist.The invention relates to an armchair, which is designated overall by the reference numeral 11. The armchair 11 comprises a support frame on which a seat 13 and a backrest 15 is held. The support frame is designed in the form of a scissor mechanism 17. The scissor mechanism 17 includes first and second support members 19, 21 which function similarly to a deck chair. For this purpose, the first and the second support element 19,21 are arranged in a cross shape and held together about a pivot point 23 to each other. For this purpose, fittings 25 are provided, which are fastened, for example, to the first support element 19 and have a first pin 27, which projects into the second support element 21 ( FIG. 5 ). Both the first support element 19 and the second support element 19 have first ends 29, 31 and second ends 33, 35. Preferably, the first and second support members 19, 21 are each formed by a pair of first and second support struts 19a, 19b and 21a, 21b, respectively. The support struts 19a, 19b and 21a, 21b are connected to each other by transverse struts 37 or spaced from each other. In the region of the second end 33 of the first support element 19, the latter is preferably curved so that a rounded (back-friendly) transition between the seat surface 13 and the backrest 15 is made possible.

Die Sitzfläche 13 ist auf einem unter der Sitzfläche 13 angeordneten Halterahmen 39 befestigt. Der Halterahmen 39 umfasst wenigstens eine Führungsstrebe 41, welche stufenlos verschiebbar an dem ersten Tragelement 19 bzw. der Haltestrebe 19a angeordnet ist. Das vordere Ende des Halterahmens 39 ist gelenkig mit dem zweiten Enden 35 verbunden. Diese Anlenkung des Halterahmens 39 an seinem vorderen und hinteren Ende ermöglicht ein Verschwenken des ersten Tragelements 19 mitsamt der Rückenlehne 15 um den Drehpunkt 23 relativ zum zweiten Tragelement 21, ohne dass diese Verschwankung durch den Halterahmen 39 blockiert werden würde. Damit der Halterahmen 39 gehalten ist und die Bewegung des ersten Tragelements 19 von der Führungsstrebe 41 nicht behindert wird, ist letztgenannte bevorzugt in einer linearen Führungskulisse 43 geführt (Figur 5). Der Führung dient ein zweiter Zapfen 45, welcher durch einen Distanzhalter 47 von einem weiteren korrespondierenden zweiten Zapfen beabstandet ist. Zwischen zweitem Zapfen 45 und Führungskulisse 43 kann ein Messinglager 47 vorgesehen sein, da Messing trockenschmierende Eigenschaften besitzt.The seat surface 13 is mounted on a support frame 39 arranged below the seat surface 13. The holding frame 39 comprises at least one guide strut 41, which is arranged to be infinitely displaceable on the first support element 19 or the holding strut 19a. The front end of the holding frame 39 is pivotally connected to the second end 35. This articulation of the holding frame 39 at its front and rear end allows pivoting of the first support member 19 together with the backrest 15 about the pivot point 23 relative to the second support member 21, without this Verschwankung would be blocked by the support frame 39. So that the holding frame 39 is held and the movement of the first support element 19 is not hindered by the guide strut 41, the latter is preferably guided in a linear guide slot 43 (FIG. FIG. 5 ). The guide is a second pin 45, which is spaced by a spacer 47 from a further corresponding second pin. Between the second pin 45 and guide slot 43, a brass bearing 47 may be provided because brass has dry lubricating properties.

Figur 5 zeigt, dass es sich bei dem Beschlag 25 und der Führungskulisse 43 um Möbelbauteile handelt, welche in den ersten Haltestreben 19,19b versenkt sind. Das erste Tragelement 19 ist daher relativ zum zweiten Tragelement 21 zwischen einer ersten Endposition und einer zweiten Endposition stufenlos verschwenkbar. Die erste und zweite Endposition werden dadurch bestimmt, dass der zweite Zapfen 45 an dem oberen bzw. unteren Ende der Führungskulisse 43 anschlägt. Durch eine bestimmte Positionierung der Führungskulisse 43 an den Haltestreben 19a bzw. 19b und eine gewählte Länge der Führungskulisse 43 lassen sich die Endpositionen vorbestimmen. Durch diese konstruktiven Merkmale lässt sich also bestimmen welchen kleinsten Winkel und welchen grössten Winkel das erste und das zweite Tragelement 19,21 miteinander einschliessen. FIG. 5 shows that it is the fitting 25 and the guide slot 43 are furniture components, which are sunk in the first support struts 19,19b. The first support element 19 is therefore pivotable continuously relative to the second support element 21 between a first end position and a second end position. The first and second end positions are determined by the second pin 45 abutting the upper and lower ends of the guide slot 43, respectively. By a certain positioning of the guide slot 43 on the retaining struts 19a and 19b and a selected length of the guide slot 43, the end positions can be predetermined. By means of these design features, it is thus possible to determine which smallest angle and which maximum angle the first and the second support element 19, 21 enclose with one another.

Zur Positionierung des ersten Tragelements 19 relativ zum zweiten Tragelement 21 in einer Position zwischen den beiden Endpositionen ist ein Verstellelement vorgesehen. In dem gezeigten Ausführungsbeispiel ist das Verstellelement durch eine Gasdruckfeder 49 realisiert, wenngleich auch andere Verstellelemente wie eine (motorisch angetriebene) Spindel oder ein Federelement denkbar sind. Die Gäsdruckfeder 49 hält das erste und zweite Tragelement 19,21 in jeder beliebigen Position zwischen den beiden Endpositionen aneinander. Das Verstellelement beispielsweise in Gestalt der-Gasdruckfeder 49 ist mit seinen Enden an dem zweiten Ende 33 des ersten Tragelements und dem ersten Ende 31 des zweiten Tragelements gelenkig befestigt. Das Verstellelement 49 ist ein zweites Bauteil des Lehnstuhls 11, welches von der Führungsbahn bzw. der Führungskulisse 43 als ein erstes Bauteil separiert ist. Das Verstellelement ist von dem Benutzer des Lehnstuhls 11 während des Sitzens bedien- bzw. verstellbar.For positioning of the first support member 19 relative to the second support member 21 in a position between the two end positions, an adjusting element is provided. In the embodiment shown, the adjusting element is realized by a gas pressure spring 49, although other adjusting elements such as a (motor-driven) spindle or a spring element are conceivable. The Gäsdruckfeder 49 holds the first and second support member 19,21 in any position between the two end positions together. The adjusting element, for example, in the form of the gas spring 49 is hinged at its ends to the second end 33 of the first support member and the first end 31 of the second support member. The adjusting element 49 is a second component of the armchair 11, which is separated from the guide track or the guide slot 43 as a first component. The adjustment is operated by the user of the armchair 11 while sitting or adjustable.

Zum Lösen und Feststellen der Gasdruckfeder 49 dient ein Seilzug 50 (in den Figuren 1 und 3 angedeutet, der die Gasdruckfeder 49 mit einem Stellhebel 52 verbindet. Der Stellhebel 52 ist an einer Stelle des Lehnstuhls positioniert:, welche vom Lehnstuhlbenutzer mit einer Hand leicht erreichbar ist, bevorzugt unter der Sitzfläche 13.For releasing and locking the gas spring 49 is a cable 50 (in the FIGS. 1 and 3 indicated that connects the gas spring 49 with a lever 52. The adjusting lever 52 is positioned at a position of the armchair: which is easily accessible by the armchair user with one hand, preferably under the seat 13.

Damit das erste Ende 29 des ersten Tragelements während des Verstellen der Rückenlehne 15 leicht am Boden entlanggleitet sind an diesem Ende Rollen 51 angeordnet. Optional ist der Lehnstuhl mit einer höhenverstellbaren Kopfstütze 52 ausgestattet. Optionale Armlehnen 53 sind wie aus dem Stand der Technik bekannt mit drei Gelenken ausgestattet, um die Verstellbarkeit der Rückenlehne 15 nicht zu beeinträchtigen.So that the first end 29 of the first support member 15 easily slides along the base during the adjustment of the backrest rollers 51 are arranged at this end. Optionally, the armchair is equipped with a height-adjustable headrest 52. Optional armrests 53 are equipped with three hinges as known from the prior art so as not to impair the adjustability of the backrest 15.

Der erfindungsgemässe Lehnstuhl funktioniert wie folgt: Zur Verstellung der Neigung der Rückenlehne 15 betätigt der Benutzter den Stellhebel 52. Die Gasdruckfeder ist nun entriegelt. Gibt der Benutzer keinen Druck auf die Rückenlehne 13 so drückt die Gasdruckfeder das erste Ende 31 und das zweite Ende 33 auseinander und die Rückenlehne wird aufgerichtet, bis die Endposition erreicht wird bei der der zweite Zapfen 45 an den oberen Rand der Führungskulisse 43 anschlägt. Wünscht der Benutzer eine Position vor dieser Endposition, so lässt er den Stellhebel 52 los und die Gasdruckfeder wird arretiert. So ist jede Position zwischen den beiden Endpositionen einstellbar. Ist die Gasdruckfeder 49 gelöst, so kann der Benutzer durch Druck auf die Rückenlehne den Winkel zwischen dem ersten und zweiten Trageelement vergrössern. Ist die gewünschte Position erreicht, so lässt sich die Gasdruckfeder 49 durch Loslassen des Stellhebels 52 arretieren. Bevorzugt aus der Endposition mit weit nach hinten gelegter Rückenlehne 15 lässt sich der Lehnstuhl noch in eine Wippposition überführen. Dafür das zweite Tragelement im Bereich des ersten Endes 31 nach oben aufgebogen und bildet einen Wippfortsatz 55. Durch Gewichtsverteilung kann der Benutzer den Lehnstuhl 11 dazu bringen nur mit dem Wippfortsatz 55 auf dem Untergrund aufzuliegen und die ersten Enden 29 anzuheben.The inventive reclining chair works as follows: To adjust the inclination of the backrest 15, the user actuates the adjusting lever 52. The gas spring is now unlocked. If the user does not apply pressure to the backrest 13, the gas spring forces the first end 31 and the second end 33 apart and the backrest is raised until the end position is reached at which the second pin 45 abuts against the upper edge of the guide slot 43. If the user wants a position before this end position, he lets go of the lever 52 and the gas spring is locked. So every position between the two end positions is adjustable. If the gas spring 49 is released, the user can increase the angle between the first and second support element by pressure on the backrest. Once the desired position has been reached, the gas pressure spring 49 can be locked by releasing the adjusting lever 52. Preferably, from the end position with the backrest 15 laid far back, the armchair can still be converted into a rocking position. By weight distribution, the user can bring the armchair 11 to rest only with the Wippfortsatz 55 on the ground and raise the first ends 29.

Der erfindungsgemässe Lehnstuhl lässt sich durch eine Scherenmechanik 17 in verschiedene Rückenlehnen-Positionen überführen und in der gewünschten Position fixieren. Dazu bedarf es keiner aufwendigen mechanischen Konstruktion, sondern vielmehr wird ein einfaches Scherenmechanikprinzip angewendet. Die Fixierung in der gewünschten Position erfolgt durch eine Gasdruckfeder 49, welche durch einen Seilzug 50 gesperrt werden kann und freigegeben werden kann.The inventive armchair can be converted by a scissors mechanism 17 in different backrest positions and fix in the desired position. This requires no elaborate mechanical construction, but rather a simple scissors mechanism is applied. The fixation in the desired position by a gas spring 49, which can be locked by a cable 50 and can be released.
