Definitions
- the invention relates to a chair, in particular armchair, with a backrest, a seat and a foot part, wherein the backrest and the foot part are pivotally arranged, wherein the backrest and the foot part are connected to each other below the seat via a coupling linkage, wherein the coupling linkage for transmitting a pivoting movement of the backrest is formed on the foot part, wherein the coupling linkage between a sitting position with steeper seat back and swiveled foot part and a reclining position with flat-set backrest and swung-foot part is adjustable.
- Such seating allow the user to take either a sitting position or a reclining position on the seating.
- a motor drive for adjusting the seat from the sitting position in the lying position and back.
- the adjustment of the chair between the sitting position and the reclining position is carried out by a purely mechanical coupling of the backrest with the foot part via a coupling linkage below the seat.
- the coupling linkage transmits the pivoting movement of the backrest on the foot part in such a way that the foot part assumes a swung-out position when the backrest is tilted backwards, ie, when the backrest is tilted forwards, ie, when the backrest is set more steeply, a pivoted-in position.
- the backrest In the sitting position, the backrest is therefore arranged more or less upright and the foot part pivoted so far that it does not affect sitting on the chair. From this position, the seat can be placed in a reclining position, to which the backrest is pivoted backwards. For this purpose, the user of the chair in a sitting position must shift his weight to the rear and press against the backrest. Since the backrest is connected via the coupling linkage with the foot part, the pivoting back of the backrest leads to a pivoting of the foot part forward in a position in which the user can place his feet or legs on the foot part.
- the operator To bring the seating back into the sitting position, the operator must exert pressure on the forwardly pivoted footboard, which is large enough to swing the footboard. This results in a more upright position as a result of the coupling of the foot part with the backrest via the coupling linkage, and indeed until the original sitting position of the chair is restored.
- the invention is therefore based on the object, the aforementioned and previously described in more detail seating furniture in such a way and further that it can be made easier and cheaper, without compromising the comfort in adjusting the chair.
- both an adjustment of the coupling linkage from the sitting position and from the lying position can only take place against a restoring force of the at least one spring means.
- the adjustment of the coupling linkage from the sitting position or from the lying position on a first piece of the adjustment path leads to a compression or the like of the spring means against its restoring force.
- This can, if the restoring forces and the spring characteristic are selected accordingly, be achieved that the coupling linkage is secured in the lying position and / or in the sitting position against unintentional adjustment.
- the seating does not unintentionally move from a sitting position to a reclining position or vice versa passes. But this is not necessarily the case. It may for example also be provided a lock or the like, which prevents a corresponding adjustment of the coupling linkage of the sitting position and the lying position and / or vice versa.
- the at least one spring means when adjusting the coupling linkage the movement of the same from a certain adjustment to supported in the sitting position on the one hand and to the lying position on the other.
- This support can be preferably by appropriate choice of the restoring force and the spring characteristic such that the coupling linkage is moved independently, so without further intervention of the operator, in particular without further effort by the operator a remaining adjustment to the sitting position and a residual adjustment in the lying position ,
- the adjustment of the coupling linkage can be supported by a single spring means both when adjusting in the lying position and when adjusting in the sitting position in any case over a certain adjustment until reaching the desired position of the coupling linkage, in particular automatically.
- the seating can be made simpler overall and composed of fewer components.
- not more spring means are required, each not only the adjustment of the coupling linkage in one direction but also support in the opposite direction.
- a spring means is sufficient. But it can also be provided a plurality of spring means. Then the restoring forces of each spring means act in the sitting position of the coupling linkage an adjustment towards the lying position and in the lying position of the coupling linkage of an adjustment towards the sitting position.
- the seating furniture may be a chair, a sofa, a couch, a garden furniture or the like.
- the chair may alternatively or additionally comprise rollers for moving the chair.
- the seating can be designed so that the seating can be moved together with the user located thereon.
- the backrest and the foot are connected to each other below the seat via a coupling rod. It is not necessarily important that the connection of the backrest is provided with the foot part of the coupling rod completely below the seat.
- the coupling linkage can in principle also be arranged offset in sections above the level of the seat and / or laterally relative thereto. In principle, therefore, any arrangement of the coupling linkage, which does not restrict the use of the chair, allowed because the coupling rod runs over the seat on which the user should take place.
- the coupling linkage is preferably arranged completely underneath the seat and not laterally opposite it.
- the backrest and the foot part are connected directly to the coupling linkage. It is basically sufficient if the backrest and the foot part are connected to one another via the coupling linkage.
- the backrest of the chair is placed significantly steeper in the sitting position, as is the case in the lying position.
- the backrest does not have to be vertical in the sitting position. Rather, the backrest will preferably assume a slight inclination relative to the vertical even in the sitting position.
- the backrest is set much flatter relative to the vertical, as is the case in the sitting position of the coupling linkage. This is achieved by pivoting the backrest backwards and thus increasing the angle to the vertical.
- the coupling linkage when adjusting between the sitting position and the reclining position occupies an intermediate position and that the coupling linkage is connected to the spring means, that the restoring force of the spring means an adjustment of the coupling linkage from the intermediate position to the sitting position and supported in the lying position.
- the restoring force of the spring means supports the further adjustment of the coupling linkage until reaching the sitting position or the lying position.
- the spring means preferably ensures that the sitting position or the lying position is achieved automatically. So it does not come to an incomplete adjustment of the chair, which could reduce the seating comfort.
- the spring means is preferably a gas spring.
- the restoring force of the gas spring is caused by a compressed gas acting on a piston arranged in a cylinder. Due to the structure of the gas spring, the restoring force is always directed in the extension direction of the piston rod of the gas spring.
- the gas spring By the gas spring, the applied restoring forces and the spring characteristic of the gas spring by simple and known from the prior art measures, such as a variation of the piston geometry or the gas pressure, adjusted precisely and adapted to the requirements of the corresponding chair.
- at least two, preferably different, gas springs can be provided. The plurality of gas springs is then compressed and pulled apart substantially parallel to the adjustment of the coupling linkage. If anything, the majority of gas springs work in opposite directions only on a small adjustment path.
- the gas spring is maximally shortened in the intermediate position. This means that the piston rod is inserted in any other position further into the cylinder of the gas spring than in the intermediate position. In other words, the gas spring in the intermediate position does not have to be completely pushed together. Due to the fact that the gas spring is maximally shortened in the intermediate position, the gas spring supports the further adjustment of the coupling linkage, regardless of whether the coupling linkage from the intermediate position in the direction of Sitting position or adjusted in the direction of the lying position.
- the spring means is supported at one end on the coupling linkage and at the other end to a stationary component of the chair.
- the coupling linkage used can be relatively easily formed and designed.
- the spring means must not be directly connected to the coupling rod on the one hand and the fixed component on the other hand. It is sufficient that the spring means between the fixed member and the coupling linkage is arranged.
- a particularly simple embodiment of the seat is achieved in that the fixed component is at least one side part of the chair or is fixed to at least one side part of the chair. From the side part also high forces can be derived to the ground usually.
- the fixed component may be given by the seat of the chair. This has the advantage, for example, that all relevant components for the adjustment of the seat are combined in a skeleton, which can be installed in very different seating.
- a structurally simple and inexpensive to manufacture embodiment of the chair is achieved when the coupling rod one, preferably directly, with the Spring means and the foot part coupled coupling rod and, preferably also directly, coupled to the backrest joint rod comprises.
- the coupling rod one, preferably directly, with the Spring means and the foot part coupled coupling rod and, preferably also directly, coupled to the backrest joint rod comprises.
- the articulated rod can be connected directly to the coupling rod.
- the foot part is pivotally held on the seat.
- the seat can ultimately assume a stabilizing function and makes a more complex construction and connection of the foot to the seating unnecessary.
- the seat is designed to be stationary relative to at least one side part, in particular two side parts of the seat arranged on opposite sides of the seat. In this way, a high stability of the chair is obtained.
- Fig. 1 is designed as a chair seating 1 schematically shown in a vertical section.
- the sectional plane is arranged in the direction behind the front and thus not shown side part of the chair 1.
- the seat 1 comprises a backrest 2, a seat 3 and a foot part 4.
- the seat 3 is fixedly connected to a rear side part 5 in the viewing direction.
- the backrest 2 and the foot part 4 are both pivotally mounted on the seat 3.
- the backrest 2 and the foot part 4 are connected to each other below the seat 3 via a coupling linkage 6.
- the coupling linkage 6 transmits a pivoting movement of the backrest 2 on the foot part 4 or a pivoting movement of the foot part 4 on the backrest. 2
- the coupling rod 6 By pivoting the backrest 2 to the rear, the coupling rod 6 from the in the Fig. 1 shown sitting position in the in Fig. 2 shown lying position to be adjusted.
- the foot part 4 In the lying position of the coupling rod 6, the foot part 4 is in a swung-out position in which the user of the chair 1 can place his feet or legs on the foot part 4.
- the backrest 2 is in a shallower, ie more horizontal, position than this has been the case in the sitting position of the coupling rod 6.
- the seat 3 is fixedly attached to the two adjacent to the seat 3, substantially identically formed side panels 5, of which as a result of the sectional view, only the rear side part 5 is shown in the viewing direction. Therefore, the position of the seat 3 when adjusting the coupling rod 6 from the sitting position to the lying position and back does not change. If necessary, however, it could be provided using known measures that also adjusts the seat when adjusting the coupling linkage.
- the coupling linkage 6 is connected to a spring means 7 designed as a gas spring.
- the gas spring 7 is supported by means of a bar 9 extending between the side parts 5 of the seat 1 and fastened to the side parts 5 via connecting plates 8.
- the coupling linkage 6 comprises only a coupling rod 12 which is connected directly to the foot part 4 and the gas spring 7, and a hinge rod 13 which is directly connected pivotally connected directly to the backrest 2 on the one hand and the coupling rod 12.
- the articulation point 14 of the articulated rod 13 to the backrest 2 in the lying, intermediate and sitting position of the coupling rod 6 is higher than the articulation point 15 of the articulated rod to the coupling rod 12.
- This Link point 15 is further in any position of the coupling rod 6 deeper than the pivot point 16 of the coupling rod 12 on the foot part 4th
- the coupling rod 12 is also bent in an S-shape, wherein a bend 17 of the coupling rod 6 of the point 18 of the gas spring 7 is assigned.
- the point of application 18 of the gas spring 7 on the stationary component of the chair, in this case a protruding from the spar arm 19, is always lower than the point 18 between the gas spring 7 and coupling rod 12th
Abstract
Description
Die Erfindung betrifft ein Sitzmöbel, insbesondere Sessel, mit einer Rückenlehne, einem Sitz und einem Fußteil, wobei die Rückenlehne und das Fußteil schwenkbar angeordnet sind, wobei die Rückenlehne und das Fußteil unterhalb des Sitzes über ein Koppelgestänge miteinander verbunden sind, wobei das Koppelgestänge zum Übertragen einer Schwenkbewegung der Rückenlehne auf das Fußteil ausgebildet ist, wobei das Koppelgestänge zwischen einer Sitzstellung mit steiler gestellter Rückenlehne und eingeschwenktem Fußteil sowie einer Liegestellung mit flacher gestellter Rückenlehne und ausgeschwenktem Fußteil verstellbar ist.The invention relates to a chair, in particular armchair, with a backrest, a seat and a foot part, wherein the backrest and the foot part are pivotally arranged, wherein the backrest and the foot part are connected to each other below the seat via a coupling linkage, wherein the coupling linkage for transmitting a pivoting movement of the backrest is formed on the foot part, wherein the coupling linkage between a sitting position with steeper seat back and swiveled foot part and a reclining position with flat-set backrest and swung-foot part is adjustable.
Derartige Sitzmöbel erlauben es dem Benutzer, wahlweise eine Sitzstellung oder eine Liegestellung auf dem Sitzmöbel einzunehmen. Aus Gründen der Kostenersparnis wird auf die Verwendung eines motorischen Antriebs zum Verstellen des Sitzmöbels von der Sitzstellung in die Liegestellung und zurück verzichtet. Die Verstellung des Sitzmöbels zwischen der Sitzstellung und der Liegestellung erfolgt durch eine rein mechanische Kopplung der Rückenlehne mit dem Fußteil über ein Koppelgestänge unterhalb des Sitzes. Das Koppelgestänge überträgt die Schwenkbewegung der Rückenlehne derart auf das Fußteil, dass das Fußteil bei nach hinten geschwenkter Rückenlehne, d.h. flacher gestellter Rückenlehne, eine ausgeschwenkte Position einnimmt und bei nach vorne geschwenkter Rückenlehne, d.h. steiler gestellter Rückenlehne, eine eingeschwenkte Position einnimmt.Such seating allow the user to take either a sitting position or a reclining position on the seating. For reasons of cost savings is dispensed with the use of a motor drive for adjusting the seat from the sitting position in the lying position and back. The adjustment of the chair between the sitting position and the reclining position is carried out by a purely mechanical coupling of the backrest with the foot part via a coupling linkage below the seat. The coupling linkage transmits the pivoting movement of the backrest on the foot part in such a way that the foot part assumes a swung-out position when the backrest is tilted backwards, ie, when the backrest is tilted forwards, ie, when the backrest is set more steeply, a pivoted-in position.
In der Sitzstellung ist die Rückenlehne folglich mehr oder weniger aufrecht angeordnet und das Fußteil so weit eingeschwenkt, dass es das Sitzen auf dem Sitzmöbel nicht beeinträchtigt. Aus dieser Position kann das Sitzmöbel in eine Liegestellung gebracht werden, wozu die Rückenlehne nach hinten geschwenkt wird. Dazu muss der Benutzer des Sitzmöbels in sitzender Position sein Gewicht nach hinten verlagern und so gegen die Rückenlehne drücken. Da die Rückenlehne über das Koppelgestänge mit dem Fußteil verbunden ist, führt das Zurückschwenken der Rückenlehne zu einem Verschwenken des Fußteils nach vorne in eine Position, in der der Benutzer seine Füße bzw. Beine auf dem Fußteil ablegen kann.In the sitting position, the backrest is therefore arranged more or less upright and the foot part pivoted so far that it does not affect sitting on the chair. From this position, the seat can be placed in a reclining position, to which the backrest is pivoted backwards. For this purpose, the user of the chair in a sitting position must shift his weight to the rear and press against the backrest. Since the backrest is connected via the coupling linkage with the foot part, the pivoting back of the backrest leads to a pivoting of the foot part forward in a position in which the user can place his feet or legs on the foot part.
Um das Sitzmöbel wieder in die Sitzstellung zu bringen, muss der Bediener einen Druck auf das nach vorne geschwenkte Fußteil ausüben, der groß genug ist, um das Fußteil einzuschwenken. Dies führt infolge der Kopplung des Fußteils mit der Rückenlehne über das Koppelgestänge zu einem Verschwenken der Rückenlehne in eine aufrechtere Position, und zwar so weit, bis die ursprüngliche Sitzstellung des Sitzmöbels wiederhergestellt ist.To bring the seating back into the sitting position, the operator must exert pressure on the forwardly pivoted footboard, which is large enough to swing the footboard. This results in a more upright position as a result of the coupling of the foot part with the backrest via the coupling linkage, and indeed until the original sitting position of the chair is restored.
Hinsichtlich des Verstellens des Sitzmöbels zwischen der Sitzposition und der Liegeposition und umgekehrt werden zwei grundlegende Anforderungen an das Sitzmöbel gestellt. Einerseits soll sich das Sitzmöbel nicht unbeabsichtigt von einer Stellung in die andere Stellung verstellen. Andererseits soll das Verstellen des Sitzmöbels von einer Stellung in die andere möglichst komfortabel und daher mit möglichst wenig Kraftaufwand erfolgen. Um diesen Anforderungen zu entsprechen, sind Mittel vorgesehen, welche eine Verstellung des Sitzmöbels unterstützen und/oder blockieren. Dadurch ergibt sich jedoch eine recht aufwändige Konstruktion, die kostenintensiv und zeitaufwändig in der Herstellung ist.With regard to the adjustment of the seat between the sitting position and the lying position and vice versa, two basic requirements are placed on the seating. On the one hand, the seating should not inadvertently move from one position to the other position. On the other hand, the adjustment of the chair from one position to the other should be as comfortable as possible and therefore with the least possible expenditure of force. To meet these requirements, means are provided which support an adjustment of the seat and / or To block. However, this results in a rather complex construction, which is costly and time-consuming to manufacture.
Der Erfindung liegt daher die Aufgabe zugrunde, das eingangs genannte und zuvor näher beschriebene Sitzmöbel derart auszugestalten und weiterzubilden, dass es einfacher und kostengünstiger gefertigt werden kann, ohne den Komfort beim Verstellen des Sitzmöbels zu beeinträchtigen.The invention is therefore based on the object, the aforementioned and previously described in more detail seating furniture in such a way and further that it can be made easier and cheaper, without compromising the comfort in adjusting the chair.
Diese Aufgabe ist bei einem Sitzmöbel mit den Merkmalen des Oberbegriffs von Anspruch 1 dadurch gelöst, dass das Koppelgestänge derart mit einem Federmittel verbunden ist, dass die Rückstellkraft des Federmittels in der Sitzstellung des Koppelgestänges einer Verstellung hin zur Liegestellung und in der Liegestellung des Koppelgestänges einer Verstellung hin zur Sitzstellung entgegenwirkt.This object is achieved in a chair with the features of the preamble of claim 1, characterized in that the coupling linkage is connected to a spring means that the restoring force of the spring means in the sitting position of the coupling linkage of an adjustment to the lying position and in the lying position of the coupling linkage of an adjustment counteracts sitting position.
Dies bedeutet, dass sowohl eine Verstellung des Koppelgestänges aus der Sitzstellung als auch aus der Liegestellung nur gegen eine Rückstellkraft des wenigstens einen Federmittels erfolgen kann. Mit anderen Worten führt die Verstellung des Koppelgestänges von der Sitzstellung oder von der Liegestellung ausgehend auf einem ersten Stück des Verstellwegs zu einem Zusammendrücken oder dergleichen des Federmittels gegen dessen Rückstellkraft. Dadurch kann, sofern die Rückstellkräfte und die Federkennlinie entsprechend ausgewählt sind, erreicht werden, dass das Koppelgestänge in der Liegestellung und/oder in der Sitzstellung gegen ein unbeabsichtigtes Verstellen gesichert ist. Das bedeutet, dass das Sitzmöbel nicht unbeabsichtigt von einer Sitzstellung in eine Liegestellung oder umgekehrt übergeht. Dies ist aber nicht zwingend der Fall. Es kann beispielsweise auch eine Verriegelung oder dergleichen vorgesehen sein, die eine entsprechende Verstellung des Kopplungsgestänges von der Sitzposition und der Liegeposition und/oder umgekehrt verhindert.This means that both an adjustment of the coupling linkage from the sitting position and from the lying position can only take place against a restoring force of the at least one spring means. In other words, the adjustment of the coupling linkage from the sitting position or from the lying position on a first piece of the adjustment path leads to a compression or the like of the spring means against its restoring force. This can, if the restoring forces and the spring characteristic are selected accordingly, be achieved that the coupling linkage is secured in the lying position and / or in the sitting position against unintentional adjustment. This means that the seating does not unintentionally move from a sitting position to a reclining position or vice versa passes. But this is not necessarily the case. It may for example also be provided a lock or the like, which prevents a corresponding adjustment of the coupling linkage of the sitting position and the lying position and / or vice versa.
Wichtig ist in diesem Zusammenhang, dass dadurch, dass eine Verstellung des Koppelgestänges sowohl aus der Sitzstellung als auch aus der Liegestellung nur gegen eine Rückstellkraft des wenigstens einen Federmittels erfolgen kann, das wenigstens eine Federmittel beim Verstellen des Koppelgestänges die Bewegung desselben ab einem bestimmten Verstellweg bis in die Sitzposition einerseits und bis in die Liegeposition andererseits unterstützt. Diese Unterstützung kann durch geeignete Wahl der Rückstellkraft und der Federkennlinie vorzugsweise derart sein, dass das Koppelgestänge selbständig, also ohne weiteres Eingreifen des Bedieners, insbesondere ohne weiteren Kraftaufwand durch den Bediener einen restlichen Verstellweg bis in die Sitzstellung und einen restlichen Verstellweg in die Liegeposition bewegt wird.It is important in this context that the fact that an adjustment of the coupling linkage can take place both from the sitting position and from the lying position only against a restoring force of the at least one spring means, the at least one spring means when adjusting the coupling linkage the movement of the same from a certain adjustment to supported in the sitting position on the one hand and to the lying position on the other. This support can be preferably by appropriate choice of the restoring force and the spring characteristic such that the coupling linkage is moved independently, so without further intervention of the operator, in particular without further effort by the operator a remaining adjustment to the sitting position and a residual adjustment in the lying position ,
Mit anderen Worten kann die Verstellung des Koppelgestänges durch ein einziges Federmittel sowohl bei Verstellung in die Liegestellung als auch bei Verstellung in die Sitzstellung jedenfalls über einen bestimmten Verstellweg bis zum Erreichen der gewünschten Stellung des Koppelgestänges unterstützt werden, insbesondere selbsttätig erfolgen. Dadurch kann das Sitzmöbel insgesamt einfacher aufgebaut und aus weniger Bauteilen zusammengesetzt werden. Insbesondere sind nicht mehrere Federmittel erforderlich, die jeweils nur die Verstellung des Koppelgestänges in eine Richtung nicht aber auch in die Gegenrichtung unterstützen. Grundsätzlich ist ein Federmittel ausreichend. Es kann aber auch eine Mehrzahl von Federmitteln vorgesehen sein. Dann wirken die Rückstellkräfte jedes einzelnen Federmittels in der Sitzstellung des Koppelgestänges einer Verstellung hin zur Liegestellung und in der Liegestellung des Koppelgestänges einer Verstellung hin zur Sitzstellung entgegen.In other words, the adjustment of the coupling linkage can be supported by a single spring means both when adjusting in the lying position and when adjusting in the sitting position in any case over a certain adjustment until reaching the desired position of the coupling linkage, in particular automatically. As a result, the seating can be made simpler overall and composed of fewer components. In particular, not more spring means are required, each not only the adjustment of the coupling linkage in one direction but also support in the opposite direction. Basically, a spring means is sufficient. But it can also be provided a plurality of spring means. Then the restoring forces of each spring means act in the sitting position of the coupling linkage an adjustment towards the lying position and in the lying position of the coupling linkage of an adjustment towards the sitting position.
Bei den Sitzmöbeln kann es sich um ein Sessel, ein Sofa, eine Liege, ein Gartenmöbel oder dergleichen handeln. Das Sitzmöbel kann alternativ oder zusätzlich Rollen zum Verfahren des Sitzmöbels aufweisen. Bedarfsweise kann das Sitzmöbel so ausgestaltet sein, dass das Sitzmöbel mitsamt dem sich darauf befindlichen Benutzer verfahren werden kann.The seating furniture may be a chair, a sofa, a couch, a garden furniture or the like. The chair may alternatively or additionally comprise rollers for moving the chair. If necessary, the seating can be designed so that the seating can be moved together with the user located thereon.
Um die Nutzung des Sitzmöbels nicht einzuschränken, sind die Rückenlehne und das Fußteil unterhalb des Sitzes über ein Koppelgestänge miteinander verbunden. Es kommt dabei nicht zwingend darauf an, dass die Verbindung der Rückenlehne mit dem Fußteil über das Koppelgestänge vollständig unterhalb des Sitzes vorgesehen ist. Das Koppelgestänge kann grundsätzlich abschnittsweise auch über dem Niveau des Sitzes und/oder seitlich gegenüber diesem versetzt angeordnet sein. Grundsätzlich ist also jede Anordnung des Koppelgestänges, welche die Nutzung des Sitzmöbels nicht einschränkt, zulässig, weil das Koppelgestänge über den Sitz verläuft, auf dem der Benutzer Platz nehmen soll. Bevorzugt ist das Koppelgestänge aber vollständig unterhalb des Sitzes und nicht seitlich gegenüber diesem hervorragend angeordnet.In order not to restrict the use of the seat, the backrest and the foot are connected to each other below the seat via a coupling rod. It is not necessarily important that the connection of the backrest is provided with the foot part of the coupling rod completely below the seat. The coupling linkage can in principle also be arranged offset in sections above the level of the seat and / or laterally relative thereto. In principle, therefore, any arrangement of the coupling linkage, which does not restrict the use of the chair, allowed because the coupling rod runs over the seat on which the user should take place. However, the coupling linkage is preferably arranged completely underneath the seat and not laterally opposite it.
Ferner ist nicht erforderlich, dass die Rückenlehne und das Fußteil unmittelbar mit dem Koppelgestänge verbunden sind. Es reicht grundsätzlich aus, wenn die Rückenlehne und das Fußteil über das Koppelgestänge miteinander verbunden sind.Furthermore, it is not necessary that the backrest and the foot part are connected directly to the coupling linkage. It is basically sufficient if the backrest and the foot part are connected to one another via the coupling linkage.
Die Rückenlehne des Sitzmöbels ist in der Sitzstellung deutlich steiler gestellt, als dies in der Liegestellung der Fall ist. Die Rückenlehne muss in der Sitzstellung jedoch nicht vertikal gestellt sein. Vielmehr wird die Rückenlehne vorzugsweise auch in der Sitzstellung eine leichte Schrägstellung gegenüber der Vertikalen einnehmen. In der Liegestellung ist die Rückenlehne bezogen auf die Vertikale deutlich flacher gestellt, als dies in der Sitzstellung des Koppelgestänges der Fall ist. Dies wird erreicht, indem die Rückenlehne nach hinten geschwenkt und somit der Winkel zur Vertikalen vergrößert wird.The backrest of the chair is placed significantly steeper in the sitting position, as is the case in the lying position. However, the backrest does not have to be vertical in the sitting position. Rather, the backrest will preferably assume a slight inclination relative to the vertical even in the sitting position. In the lying position, the backrest is set much flatter relative to the vertical, as is the case in the sitting position of the coupling linkage. This is achieved by pivoting the backrest backwards and thus increasing the angle to the vertical.
Bei einer ersten bevorzugten Ausgestaltung des Sitzmöbels ist vorgesehen, dass das Koppelgestänge beim Verstellen zwischen der Sitzstellung und der Liegestellung eine Zwischenstellung einnimmt und dass das Koppelgestänge derart mit dem Federmittel verbunden ist, dass die Rückstellkraft des Federmittels eine Verstellung des Koppelgestänges von der Zwischenstellung in die Sitzstellung und in die Liegestellung unterstützt. Nachdem das Koppelgestänge aus der Sitzstellung oder der Liegestellung bis in eine Zwischenstellung verstellt worden ist, unterstützt die Rückstellkraft des Federmittels die weitere Verstellung des Koppelgestänges bis zum Erreichen der Sitzstellung bzw. der Liegestellung. Das Federmittel sorgt vorzugsweise dafür, dass die Sitzstellung oder die Liegestellung selbsttätig erreicht wird. Es kommt also nicht zu einer unvollständigen Verstellung des Sitzmöbels, welche den Sitzkomfort schmälern könnte.In a first preferred embodiment of the chair it is provided that the coupling linkage when adjusting between the sitting position and the reclining position occupies an intermediate position and that the coupling linkage is connected to the spring means, that the restoring force of the spring means an adjustment of the coupling linkage from the intermediate position to the sitting position and supported in the lying position. After the coupling rod has been adjusted from the sitting position or lying position to an intermediate position, the restoring force of the spring means supports the further adjustment of the coupling linkage until reaching the sitting position or the lying position. The spring means preferably ensures that the sitting position or the lying position is achieved automatically. So it does not come to an incomplete adjustment of the chair, which could reduce the seating comfort.
Um ein möglichst komfortables Verstellen des Koppelgestänges zu ermöglich, handelt es sich bei dem Federmittel vorzugsweise um eine Gasfeder. Die Rückstellkraft der Gasfeder wird durch ein komprimiertes auf einen in einem Zylinder angeordneten Kolben wirkendes Gas hervorgerufen. Aufgrund des Aufbaus der Gasfeder ist die Rückstellkraft stets in Ausschubrichtung der Kolbenstange der Gasfeder gerichtet. Durch die Gasfeder können die ausgeübten Rückstellkräfte sowie die Federkennlinie der Gasfeder durch einfache und aus dem Stand der Technik bekannte Maßnahmen, wie beispielsweise einer Variation der Kolbengeometrie oder des Gasdrucks, präzise eingestellt und an die Anforderungen des entsprechenden Sitzmöbels angepasst werden. Um diese Anpassungsmöglichkeiten noch zu verbessern, können auch wenigstens zwei, vorzugsweise unterschiedliche, Gasfedern vorgesehen sein. Die Mehrzahl von Gasfedern wird dann beim Verstellen des Koppelgestänges im Wesentlichen parallel zusammengedrückt und auseinandergezogen. Wenn überhaupt, arbeiten die Mehrzahl von Gasfedern nur auf einem geringen Verstellweg gegenläufig.In order to allow the most comfortable adjustment of the coupling linkage, it is in the spring means is preferably a gas spring. The restoring force of the gas spring is caused by a compressed gas acting on a piston arranged in a cylinder. Due to the structure of the gas spring, the restoring force is always directed in the extension direction of the piston rod of the gas spring. By the gas spring, the applied restoring forces and the spring characteristic of the gas spring by simple and known from the prior art measures, such as a variation of the piston geometry or the gas pressure, adjusted precisely and adapted to the requirements of the corresponding chair. In order to improve these adaptation possibilities even more, at least two, preferably different, gas springs can be provided. The plurality of gas springs is then compressed and pulled apart substantially parallel to the adjustment of the coupling linkage. If anything, the majority of gas springs work in opposite directions only on a small adjustment path.
In diesem Zusammenhang bietet es sich an, wenn die Gasfeder in der Zwischenstellung maximal verkürzt ist. Dies bedeutet, dass die Kolbenstange in keiner anderen Stellung weiter in den Zylinder der Gasfeder eingeschoben ist als in der Zwischenstellung. Mit anderen Worten muss die Gasfeder in der Zwischenstellung nicht vollständig zusammengeschoben sein. Dadurch, dass die Gasfeder in der Zwischenstellung maximal verkürzt ist, unterstützt die Gasfeder die weitere Verstellung des Koppelgestänges, unabhängig davon, ob das Koppelgestänge von der Zwischenstellung in Richtung der Sitzstellung oder in Richtung der Liegestellung verstellt wird.In this context, it makes sense if the gas spring is maximally shortened in the intermediate position. This means that the piston rod is inserted in any other position further into the cylinder of the gas spring than in the intermediate position. In other words, the gas spring in the intermediate position does not have to be completely pushed together. Due to the fact that the gas spring is maximally shortened in the intermediate position, the gas spring supports the further adjustment of the coupling linkage, regardless of whether the coupling linkage from the intermediate position in the direction of Sitting position or adjusted in the direction of the lying position.
Bei einer konstruktiv bevorzugten Ausführungsform des Sitzmöbels ist das Federmittel mit einem Ende am Koppelgestänge und mit dem anderen Ende an einem feststehenden Bauteil des Sitzmöbels abgestützt. Auf diese Weise kann das verwendete Koppelgestänge vergleichsweise einfach ausgebildet und ausgelegt werden. Dabei muss das Federmittel nicht unmittelbar mit dem Koppelgestänge einerseits und dem feststehenden Bauteil andererseits verbunden sein. Es ist ausreichend, dass das Federmittel zwischen dem feststehenden Bauteil und dem Koppelgestänge angeordnet ist.In a structurally preferred embodiment of the chair, the spring means is supported at one end on the coupling linkage and at the other end to a stationary component of the chair. In this way, the coupling linkage used can be relatively easily formed and designed. In this case, the spring means must not be directly connected to the coupling rod on the one hand and the fixed component on the other hand. It is sufficient that the spring means between the fixed member and the coupling linkage is arranged.
Eine besonders einfache Ausgestaltung des Sitzmöbels wird dadurch erzielt, dass das feststehende Bauteil wenigstens ein Seitenteil des Sitzmöbels ist oder an wenigstens einem Seitenteil des Sitzmöbels festgelegt ist. Vom Seitenteil können zudem in der Regel hohe Kräfte an den Boden abgeleitet werden.A particularly simple embodiment of the seat is achieved in that the fixed component is at least one side part of the chair or is fixed to at least one side part of the chair. From the side part also high forces can be derived to the ground usually.
Alternativ dazu kann das feststehende Bauteil auch durch den Sitz des Sitzmöbels gegeben sein. Dies hat beispielsweise den Vorteil, dass alle für die Verstellung des Sitzmöbels relevanten Bauteile in einem Grundgerüst zusammengefasst sind, welches in sehr verschiedenen Sitzmöbeln verbaut werden kann.Alternatively, the fixed component may be given by the seat of the chair. This has the advantage, for example, that all relevant components for the adjustment of the seat are combined in a skeleton, which can be installed in very different seating.
Eine konstruktiv einfache und kostengünstig herzustellende Ausgestaltung des Sitzmöbels wird erreicht, wenn das Koppelgestänge eine, vorzugsweise unmittelbar, mit dem Federmittel und dem Fußteil gekoppelte Koppelstange und eine, ebenfalls vorzugsweise unmittelbar, mit der Rückenlehne gekoppelte Gelenkstange umfasst. Auf diese Weise wird die Anzahl der notwendigen Bauteile des Koppelgestänges verringert. Dazu kann alternativ oder zusätzlich die Gelenkstange unmittelbar mit der Koppelstange verbunden sein.A structurally simple and inexpensive to manufacture embodiment of the chair is achieved when the coupling rod one, preferably directly, with the Spring means and the foot part coupled coupling rod and, preferably also directly, coupled to the backrest joint rod comprises. In this way, the number of necessary components of the coupling linkage is reduced. For this purpose, alternatively or additionally, the articulated rod can be connected directly to the coupling rod.
Um die Schwenkbarkeit der Rückenlehne einerseits konstruktiv einfach sicherstellen zu können und andererseits eine geeignete Übertragung der Kräfte von der Rückenlehne auf das Koppelgestänge zu ermöglichen, bietet es sich an, wenn die Rückenlehne schwenkbar am Sitz gehalten ist.In order to ensure the pivotability of the backrest on the one hand structurally simple and on the other hand to allow a suitable transmission of forces from the backrest to the coupling rod, it makes sense, when the backrest is pivotally held on the seat.
Alternativ oder zusätzlich kann vorgesehen sein, dass das Fußteil schwenkbar am Sitz gehalten ist. Der Sitz kann dabei letztlich eine Stabilisierungsfunktion übernehmen und macht eine aufwändigere Konstruktion und Anbindung des Fußteils an das Sitzmöbel überflüssig.Alternatively or additionally, it may be provided that the foot part is pivotally held on the seat. The seat can ultimately assume a stabilizing function and makes a more complex construction and connection of the foot to the seating unnecessary.
Besonders zweckmäßig ist es in diesem Zusammenhang, wenn der Sitz feststehend gegenüber wenigstens einem Seitenteil, insbesondere zwei auf gegenüberliegenden Seiten des Sitzes angeordnete Seitenteile des Sitzmöbels, ausgebildet ist. Auf diese Weise wird eine hohe Stabilität des Sitzmöbels erhalten.In this context, it is particularly expedient if the seat is designed to be stationary relative to at least one side part, in particular two side parts of the seat arranged on opposite sides of the seat. In this way, a high stability of the chair is obtained.
Die Erfindung wird nachfolgend anhand lediglich einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Die Zeichnung zeigt:

Der Sitz 3 ist fest an den beiden an den Sitz 3 angrenzenden, in Wesentlichen identisch ausgebildeten Seitenteilen 5 befestigt ist, von denen infolge der Schnittansicht lediglich das in Blickrichtung hintere Seitenteil 5 dargestellt ist. Daher verändert sich die Position des Sitzes 3 beim Verstellen des Koppelgestänges 6 von der Sitzstellung in die Liegestellung und zurück nicht. Bedarfsweise könnte jedoch unter Anwendung bekannter Maßnahmen vorgesehen sein, dass sich beim Verstellen des Koppelgestänges auch der Sitz verstellt.The
Das Koppelgestänge 6 ist mit einem als Gasfeder 7 ausgebildeten Federmittel verbunden. Die Gasfeder 7 ist über einen sich zwischen den Seitenteilen 5 des Sitzmöbels 1 erstreckenden und über Anschlussplatten 8 an den Seitenteilen 5 befestigten Holm 9 abgestützt.The

Wird die Rückstellkraft der Gasfeder 7 überwunden, kommt es zu einer Verstellung des Koppelgestänges 6, bis dieses eine Zwischenstellung einnimmt. Über diesen Verstellweg muss durchgängig die Rückstellkraft der Gasfeder 7 überwunden werden. Wird, bevor das Koppelgestänge 6 die Zwischenposition eingenommen hat, der Druck auf das Fußteil 4 aufgehoben, sorgt die Gasfeder 7 dafür, dass sich das Koppelgestänge 6 sehr leicht, vorzugsweise selbsttätig, zurück in die Liegestellung verstellt.If the restoring force of the

Ist diese Zwischenposition erreicht und wird die Rückenlehne 2 weiter nach hinten verschwenkt, wird die weitere Verschwenkung des Koppelgestänges 6 durch die Gasdruckfeder 7 unterstützt. Dies ist der Fall, weil die weitere Verschwenkung der Rückenlehne 2 zu einem Ausziehen der Kolbenstange 11 aus dem Zylinder 10 der Gasfeder führt. Bei entsprechender Federkennlinie erfolgt das weitere Verschwenken des Koppelgestänges bis in die Liegestellung selbsttätig, also ohne weiteres Zutun des Bedieners.If this intermediate position is reached and the
Bei dem dargestellten Ausführungsbeispiel umfasst das Koppelgestänge 6 lediglich eine Koppelstange 12, die direkt mit dem Fußteil 4 und der Gasfeder 7 verbunden ist, und eine Gelenkstange 13, die direkt mit der Rückenlehne 2 einerseits und der Koppelstange 12 andererseits schwenkbar verbunden ist.In the illustrated embodiment, the
Die Koppelstange 12 ist dabei länger ausgebildet als die Gelenkstange 13. Zudem ist der Anlenkpunkt 14 der Gelenkstange 13 an die Rückenlehne 2 in der Liege-, Zwischen- und Sitzstellung des Koppelgestänges 6 höher angeordnet als der Anlenkpunkt 15 des Gelenkstange an die Koppelstange 12. Dieser Anlenkpunkt 15 ist ferner in jeder Stellung des Koppelgestänges 6 tiefer als der Anlenkpunkt 16 der Koppelstange 12 am Fußteil 4.In addition, the
Die Koppelstange 12 ist ferner S-förmig gebogen, wobei einer Biegung 17 der Koppelstange 6 der Angriffspunkt 18 der Gasfeder 7 zugeordnet ist.
