Description

Sesselarmchair

Die Erfindung betrifft einen Sessel mit einer gegenüber einer Sitzfläche verstellbaren Rückenlehne, wobei die Rückenlehne in ihrer Neigung unabhängig zur Sesselposition verstellbar ist.The invention relates to a chair with a relative to a seat adjustable backrest, wherein the backrest is adjustable independently of the chair position in their inclination.

Es sind Sessel bekannt, die zwischen einer Sitz- und Liegeposition verstellbar sind, Diese werden auch als Sitz- und Liegemöbel bezeichnet. Sie erlauben eine Verstellung der Position zwischen einer "normalen" aufrechten Sitzposition und einer etwa horizontal ausgerichteten Liegeposition. Eine eingestellte Neigung derArmchairs are known that are adjustable between a sitting and reclining position. These are also referred to as sitting and lying furniture. They allow an adjustment of the position between a "normal" upright sitting position and an approximately horizontally oriented reclining position. A set inclination of

Rückenlehne wird beibehalten bzw. die Neigung der Rückenlehne kann gesondert und unabhängig von der Position des Sessels verstellt werden.Backrest is maintained or the inclination of the backrest can be adjusted separately and independently of the position of the chair.

Bei einem derartigen, aus der DE 296 00 282 U1 bekannten Sessel ist es möglich, die Verstellung durch Verlagerung der Sitzfläche ohne größere Kräfte vorzunehmen, da ein Parallellenkersystem vorgesehen ist, das beim Verschieben der Sitzfläche das Körpergewicht bzw. den Schwerpunkt zusammen mit der Sitzfläche nach hinten verlagert. Die Rückenlehnenneigung wird über eine Gasdruckfeder eingestellt, die über ein Ventil gesteuert wird, das über einen Betätigungshebel betätigt wird.In such, from DE 296 00 282 U1 known chair, it is possible to make the adjustment by shifting the seat without major forces, as a Parallellenkersystem is provided, the body weight and the center of gravity along with the seat after moving the seat shifted behind. The backrest tilt is adjusted by a gas spring, which is controlled by a valve that is actuated by an operating lever.

Ein ähnlicher Sessel ist von der Firma Steltemeier GmbH, Lippstadt bekannt. Auch bei diesem Sessel findet eine Verstellung der Neigung der Rückenlehne über eine mittels Betätigungshebel und Ventil gesteuerte Gasdruckfeder statt.A similar chair is known by the company Steltemeier GmbH, Lippstadt. Also in this chair is an adjustment of the inclination of the backrest via a controlled by means of actuating lever and valve gas spring instead.

Solche Sessel haben den Nachteil, dass die mit dem Betätigungshebel verbundene Mechanik aufwendig und anfällig ist. Zudem muss der Benutzer den Betätigungshebel zur Verstellung der Neigung bedienen, was insbesondere in der Liegeposition schwierig ist. Ferner ist je nach Betätigungshebelausführung dessen Bedienung nicht immer intuitiv, sondern muss dem Benutzer erklärt werden.Such chairs have the disadvantage that the mechanism connected to the operating lever is complicated and prone. In addition, the user must operate the operating lever for adjusting the inclination, which is particularly difficult in the lying position. Furthermore, depending on the operating lever design, its operation is not always intuitive, but must be explained to the user.

Der Erfindung liegt die Aufgabe zugrunde, einen Sessel zu schaffen, bei dem die Neigung der Rückenlehne in besonders einfacher Weise möglich und bei dem zudem die Mechanik für die Verstellung der Rückenlehne einfach und robust aufgebaut sowie intuitiv bedienbar ist. Diese Aufgabe wird durch den in Anspruch 1 wiedergegebenen Sessel gelöst.The invention has for its object to provide a chair in which the inclination of the backrest in a particularly simple manner possible and in which also the mechanism for the adjustment of the backrest is simple and robust and intuitively operable. This object is achieved by the recited in claim 1 armchair.

Dadurch, dass der Sessel derart ausgestaltet ist, dass die Verstellung der Neigung der Rückenlehne stufenlos ohne Betätigungsmittel erfolgt, ist die Bedienung intuitiv und einfach. Ferner wird der Aufbau des Sessels vereinfacht und so robuster und zudem preiswerter in der Herstellung und Wartung.The fact that the chair is designed such that the adjustment of the inclination of the backrest is infinitely without actuating means, the operation is intuitive and simple. Furthermore, the structure of the chair is simplified and so robust and also cheaper in manufacturing and maintenance.

Unter Betätigungsmittel werden zunächst vom Bediener zu betätigende Hebel, Schrauben, Knöpfe, Räder, Drehknöpfe, Handgriffe usw. verstanden, die nach Betätigung eine Veränderung der Neigung der Rückenlehne erlauben, wozu sie beispielsweise Ventile von Gasdruckfedern auslösen, Rastmechanismen entriegeln oder Arretiermittel freigegeben. Zusätzlich werden unter Betätigungsmittel solche mechanischen Lösungen verstanden, die eine Verstellung der Neigung der Rückenlehne erst nach Freigabe einer Arretiervorrichtung durch Druck auf die Rückenlehne erlauben. Ein Beispiel einer solchen Vorrichtung ist die Verwendung einer Arretierrolle, die in der aufrechten Stellung der Rückenlehne in einer Ausnehmung gehalten wird und erst mit einer gewissen Kraft herausgedrückt werden muss, um die Bewegung der Rückenlehne zu ermöglichen.Actuating means are first understood by the operator to be operated levers, screws, knobs, wheels, knobs, handles, etc., which allow a change in the inclination of the backrest after operation, for which they trigger, for example, valves of gas springs, release locking mechanisms or released locking. In addition, actuating means are understood as meaning mechanical solutions which permit an adjustment of the inclination of the backrest only after release of a locking device by pressure on the backrest. An example of such a device is the use of a locking roller, which is held in the upright position of the backrest in a recess and must first be pushed out with a certain force to allow the movement of the backrest.

Bei der erfindungsgemäßen Lösung ist nämlich weder ein Betätigungsmittel, noch ein Rast- oder Arretiermittel notwendig. Gerade hierdurch zeichnet sich die erfindungsgemäße Lösung aus.In the solution according to the invention, neither an actuating means, nor a locking or locking means is necessary. This is precisely what distinguishes the solution according to the invention.

Besonders bevorzugt ist es, wenn die Verstellung der Neigung derart ausgestaltet ist, dass die Rückenlehne zusätzlich in beliebigen Stellungen gehalten werden kann.It is particularly preferred if the adjustment of the inclination is designed such that the backrest can be additionally held in any position.

Dann ist es nämlich möglich, die Rückenlehne nicht nur stufenlos, sondern auch ohne besondere Betätigung oder Rast- bzw. Arretiermittel in verschiedenen Stellungen anzuhalten beziehungsweise einzustellen. Die Rückenlehne kann also in beliebige Stellungen geneigt und dort gehalten werden, wenn der Benutzer sich zurücklehnt.Then it is possible to stop or adjust the backrest not only continuously, but also without special operation or locking or locking means in different positions. The backrest can therefore be tilted in any position and held there when the user leans back.

In einer ganz besonders bevorzugten Ausführungsform der Erfindung ist eine Gasdruckfeder zur Verstellung der Neigung der Rückenlehne vorgesehen, die unabhängig von ihrer jeweiligen Stellung mit einer erhöhten Anfangseinschubkraft versehen ist. Eine solche Gasdruckfeder zeichnet sich also dadurch aus, dass zur Verstellung des Kolbens der Gasdruckfeder eine bestimmte Anfangskraft überwunden werden muss, wonach die weitere Verstellung mit einer kleineren Kraft erfolgen kann. Eine solche Gasdruckfeder dient also zur Kraftunterstützung und stufenlosen Positionierung der Rückenlehne und sorgt andererseits dafür, dass die Rückenlehne in jeder Position bei zurückgelehntem Benutzter gehalten wird.In a very particularly preferred embodiment of the invention, a gas spring for adjusting the inclination of the backrest is provided, which is provided regardless of their respective position with an increased initial insertion force. Such a gas spring is thus characterized by the fact that overcome a certain initial force to adjust the piston of the gas spring must be, according to which the further adjustment can be done with a smaller force. Such a gas spring thus serves for power assistance and stepless positioning of the backrest and on the other hand ensures that the backrest is held in any position with leaning back user.

Vorzugsweise ist die Gasdruckfeder eine Reibgasfeder oder eine Gasdruckfeder mit Druckventil an der Kolbenrückseite. Reibgasfedern zeichnen sich dadurch aus, dass der Kolben über ein zusätzliches Element mit einer Reibung versehen wird, die überwunden werden muss, um ihn zu bewegen. Als solche Elemente werden teilweise Schaumstoffe verwendet, die unter einer Vorspannung an der Rohrwandung anliegen und so die notwendige zusätzliche Reibung erzeugen. Zusätzlich eignen sich solche Gasdruckfedern, bei denen der Kolben mit einem auf der Kolbenrückseite angeordneten Druckventil ausgerüstet ist, wobei das Ventil den Austausch beziehungsweise das Einschieben der Kolbenstange solange verhindert, bis eine federvorgespannten Dichtung die Kolbenbohrung freigibt.Preferably, the gas spring is a friction gas spring or a gas spring with pressure valve on the piston rear side. Friction gas springs are characterized in that the piston is provided via an additional element with a friction that must be overcome in order to move it. As such elements partially foams are used, which rest under a bias on the pipe wall and thus produce the necessary additional friction. In addition, such gas springs are suitable in which the piston is equipped with a arranged on the piston rear pressure valve, the valve prevents the replacement or insertion of the piston rod until a spring-loaded seal releases the piston bore.

Entsprechende Gasdruckfedern sind zum Beispiel von den Firmen STABILUS GmbH, Koblenz, Deutschland oder SUSPA GmbH, Altdorf, Deutschland erhältlich.Corresponding gas springs are available, for example, from the companies STABILUS GmbH, Koblenz, Germany or SUSPA GmbH, Altdorf, Germany.

Der Benutzer muss also lediglich um eine Verstellung der Neigung der Rückenlehne zu erreichen, sich nach hinten lehnen und durch zusätzliches Abdrücken, z. B. an den Armlehnen, die Anfangskraft der Gasdruckfeder überwinden. Dann lehnt sich der Benutzer so weit wie gewünscht nach hinten zurück und muss lediglich die Bewegung der Rückenlehne anhalten, um deren Position festzulegen. Wünscht der Benutzer eine weitere Erhöhung der Neigung, so kann er sich wieder unter Überwindung der Anfangskraft nach hinten lehnen, um so die weitere Verstellung der Rückenlehne zu erreichen.The user must therefore only to achieve an adjustment of the inclination of the backrest, lean backwards and by additional impressions, eg. B. on the armrests, overcome the initial force of the gas spring. Then, the user leans back as far as desired and only has to stop the movement of the backrest to determine their position. If the user wishes to further increase the inclination, he can lean backwards, overcoming the initial force, so as to achieve the further adjustment of the backrest.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung, weist die Gasdruckfeder eine geringere Ausschubkraft als Einschubkraft auf. Möchte sich der Benutzer wieder aufrichten, das heißt die Neigung der Rückenlehne verringern bzw. die Rückenlehne steiler stellen, so muss der Benutzer sich lediglich nach vorne aufrichten. Trotz der geringeren Ausschubkraft ist diese hoch genug, um die Rückenlehne zurückzustellen. Sinnvollerweise wird die Federkennlinie so gewählt, dass die Kräfte für normal gewichtige Personen zutreffend sind, d.h. diese müssen einen geringen zusätzlichen Druck durch Abstützen aufbringen, um die jeweilige Verstellung zu erreichen.According to a further preferred embodiment of the invention, the gas spring on a lower extension force than insertion force. If the user wants to straighten up again, that is to say to reduce the inclination of the backrest or to make the backrest steeper, the user merely has to rise to the front. Despite the lower pushing force, this is high enough to reset the backrest. It makes sense that the spring characteristic is chosen so that the forces for normal weight persons are accurate, ie they must apply a small additional pressure by supporting to achieve the respective adjustment.

Weitere Merkmale, Eigenschaften und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung der Zeichnung. Es zeigen:Further features, properties and advantages of the present invention will become apparent from the following description of the drawing. Show it:

In Fig. 1 bzw. 2 ist eine perspektivische Ansicht eines als Ganzes mit 1 bezeichneten erfindungsgemäßen Sessels von schräg links oben in der Sitzposition ohne Verkleidung dargestellt, d. h. es ist zum besseren Verständnis lediglich das dem Sessel 1 zugrunde liegende Gestell und seine Mechanik abgebildet. In Fig. 1 ist der Sessel 1 mit aufrechter Rückenlehne dargestellt, wohingegen die Rückenlehne in Fig. 2 nach hinten geneigt ist.In Fig. 1 and 2, a perspective view of a designated as a whole with 1 inventive chair from obliquely left above in the sitting position without paneling is shown, d. H. For better understanding, only the frame on which the chair 1 is based and its mechanism are depicted. In Fig. 1, the chair 1 is shown with an upright backrest, whereas the backrest is inclined in Fig. 2 to the rear.

Der Sessel 1 umfasst im Wesentlichen eine Sitzfläche 2, eine Rückenlehne 3, eine ausschwenkbare Beinauflage 4 sowie einen Fuß 5.The chair 1 essentially comprises a seat 2, a backrest 3, a swing-out leg rest 4 and a foot 5.

Die Sitzfläche 2 ist zur Verstellung der Position des Sessels 1 zwischen einer Sitz- und Liegeposition über ein geeignetes Lenkersystem verschiebbar, wobei die Beinauflage 4 aus ihrer eingeklappten Stellung ausfährt bzw. wieder eingeschwenkt wird. Hierbei wird die Neigung der Rückenlehne 3 nicht beeinflusst.The seat 2 is displaceable for adjusting the position of the chair 1 between a sitting and lying position via a suitable link system, wherein the leg rest 4 extends from its retracted position or is pivoted back. Here, the inclination of the backrest 3 is not affected.

Die Rückenlehne 3 umfasst ein Kopfteil 6 und ein Rückenteil 7, die jeweils aus einem Rohrrahmen gebildet und über seitliche rastbare Gelenke 8 miteinander verbunden sind, wobei zwischen den Seiten der Teile Querstreben 9 vorgesehen sind, um eine Stützfläche für die Verkleidung bzw. Polsterung auszubilden. Ferner umfasst der Sessel 1 einen sich unten an dem Rückenteil 7 anschließenden unteren Bereich 10, die einen leichten Winkel zum Rückenteil 7 ausbildet. In der dargestellten aufrechten Sitzposition ist der untere Bereich 10 etwa senkrecht und der Rückenteil 7 demgegenüber um etwa 15 Grad aus der Senkrechten nach hinten geneigt.The backrest 3 comprises a head part 6 and a back part 7, which are each formed from a tubular frame and connected to each other via lateral latching joints 8, wherein between the sides of the parts cross struts 9 are provided to a Form support surface for the lining or upholstery. Furthermore, the chair 1 comprises a lower region 10 adjoining the back part 7 at the bottom, which forms a slight angle to the back part 7. In the illustrated upright seating position of the lower portion 10 is approximately perpendicular and the back part 7, however, inclined by about 15 degrees from the vertical to the rear.

Die Rückenlehne 3 ist über den unteren Bereich 10 mit der Sitzfläche 2 bzw. deren Mechanik verbunden, wozu jeweils oben und unten an dem unteren Bereich 10 jeweils pro Seite eine entsprechende Lasche 1 1 bzw. 12 angeschweißt ist. Die Laschen 1 1 sind außen am Übergang zwischen dem Rückenteil 7 und dem Bereich 10 und die Laschen 12 mit geringem Abstand zueinander etwa mittig an der unteren Querstrebe der Rückenlehne 3 angeordnet.The backrest 3 is connected via the lower region 10 to the seat surface 2 or its mechanism, for which purpose a corresponding lug 1 1 or 12 is respectively welded to the lower region 10 at the top and bottom at each lower side. The tabs 1 1 are arranged outside at the transition between the back part 7 and the area 10 and the tabs 12 at a small distance from each other approximately centrally on the lower transverse strut of the backrest 3.

Die oberen Laschen 1 1 sind jeweils gelenkig mit einem Hebel 14 verbunden, der wiederum mit einem weiteren Hebel 16 gelenkig verbunden ist, der über einenThe upper tabs 1 1 are each pivotally connected to a lever 14, which in turn is articulated to a further lever 16, which has a

Rundstab 17 mit seinem Gegenstück auf der anderen Seite starr verbunden ist. An dem Rundstab 17 sind wiederum zwei Laschen angeschweißt, die zur gelenkigen Verbindung mit dem übrigen Sessel 1 bzw. Teile dessen Fußes 5 dienen.Rod 17 is rigidly connected to its counterpart on the other side. On the round rod 17, in turn, two tabs are welded, which serve for articulated connection with the rest of the chair 1 and parts of the foot 5.

Der zwischen der jeweiligen Lasche 11 und dem Hebel 16 angeordnete Hebel 14 weist eine etwa halbrunde Ausnehmung 18 auf, die zur beweglichen Aufnahme der hinteren Ecke der Sitzfläche 2 dient.The arranged between the respective tab 11 and the lever 16 lever 14 has an approximately semicircular recess 18, which serves for the movable receiving the rear corner of the seat 2.

Die unteren Laschen 12 sind gelenkig mit einer Gasdruckfeder 13 verbunden, die wiederum an einer Längsstrebe 15 der Sitzfläche 2 angelenkt ist, die zwischen der Vorderstrebe und der Hinterstrebe der Sitzfläche etwa mittig angeordnet und jeweils im Randbereich nach unten abgewinkelt ist. Die Gasdruckfeder 13 ist also einerseits an den Laschen 12 und andererseits über Laschen 19 mit der Längsstrebe 15 verbunden.The lower tabs 12 are pivotally connected to a gas spring 13, which in turn is hinged to a longitudinal strut 15 of the seat 2, which is arranged approximately centrally between the front strut and the rear strut of the seat and each angled downwards in the edge region. The gas spring 13 is thus connected on the one hand to the tabs 12 and on the other hand via tabs 19 with the longitudinal strut 15.

Die Gasdruckfeder 13 dient zum Verstellen der Neigung der unabhängig von der Sitzfläche 2 verstellbaren Rückenlehne 3. Es handelt sich bei der Gasdruckfeder 13 um eine besondere Gasdruckfeder, die unabhängig von ihrer jeweiligen Stellung mit einer erhöhten Anfangseinschubkraft F1 (vgl. Fig. 3) versehen ist.The gas spring 13 serves to adjust the inclination of the backrest 3, which is independent of the seat surface 2. The gas pressure spring 13 is a special gas pressure spring, which is provided with an increased initial insertion force F1 (see Fig. 3) regardless of its respective position.

Einsetzbar sind sowohl sogenannte Reibgasfedern als auch Gasdruckfedern mit Druckventil an der Kolbenrückseite, wie sie unter dem Namen Hydro-Lift ® von der Firma Stabilus bekannt sind.Can be used both so-called friction gas springs and gas springs with pressure valve on the back of the piston, as they are known under the name Hydro-Lift ® Stabilus.

Der Benutzer muss also lediglich um eine Verstellung der Neigung der Rückenlehne 3 zu erreichen, sich nach hinten lehnen und durch zusätzliches Abdrücken dieThe user must therefore only to achieve an adjustment of the inclination of the backrest 3, lean backwards and by additional impressions the

Anfangseinschubkraft F1 der Gasdruckfeder überwinden. Anschließend wirkt nur noch die verminderte Einschubkraft F2, die überwunden werden muss, so dass sich der Benutzer nun nur so weit, wie gewünscht, nach hinten zurücklehnen muss, um die gewünschte Stellung der Rückenlehne 3 einzunehmen.Overcome initial insertion force F1 of the gas spring. Then only the reduced insertion force F2, which must be overcome, so that the user now only as far as desired, must lean back to take the desired position of the backrest 3.

An dieser Stelle vermindert der Benutzer einfach den Druck, so dass durch die immer aus dem Stillstand auftretende erhöhte Anfangseinschubkraft F1 die Rückenlehne 3 an der eingestellten Stellung stehen bleibt und dort gegen die Gewichtskraft der Person gehalten wird. Der Benutzer kann sich also an jeder beliebigen Stellung der Rückenlehne 3 auch an der Rückenlehne 3 anlehnen.At this point, the user simply reduces the pressure so that the backrest 3 stops at the set position due to the increased initial insertion force F1 always occurring from a standstill, where it is held against the weight of the person. The user can therefore lean on any position of the backrest 3 and the backrest 3.

Wünscht der Benutzer eine weitere Verstellung der Neigung, so kann er sich wieder unter Überwindung der Anfangseinschubkraft F1 nach hinten lehnen, um so die Verstellung der in Rückenlehne 3 zu erreichen.If the user desires a further adjustment of the inclination, he can lean backwards, overcoming the initial insertion force F1, so as to achieve the adjustment of the backrest 3.

Die Gasdruckfeder 13 weist daneben eine geringere Ausschubkraft F3 als die Einschubkraft F2 auf. Dies ergibt sich, da die Ausschubkraft F3 etwa der Einschubkraft F2 abzüglich der Reibung entspricht.The gas spring 13 has next to a lower Ausschubkraft F3 than the insertion force F2. This results because the extension force F3 corresponds approximately to the insertion force F2 minus the friction.

Möchte sich der Benutzer wieder aufrichten, das heißt die Neigung der Rückenlehne verringern bzw. die Rückenlehne 3 steiler stellen, so muss der Benutzer sich lediglich nach vorne aufrichten. Die Ausschubkraft F3 ist also so gewählt, dass die Rückenlehne 3 den Benutzer zwar nicht aus dem Sessel 1 "schiebt", aber die Rückenlehne 3 trotzdem wiederaufstellt. Die Einschubkräfte F1 und F2 nehmen, wie bei Federn allgemein üblich, über den Verstellweg leicht zu. Entsprechend nimmt auch die Ausschubkraft F3 über den Verstellweg leicht ab.If the user wants to straighten up again, that is to say to reduce the inclination of the backrest or to make the backrest 3 steeper, then the user merely has to rise to the front. The extension force F3 is thus selected so that the backrest 3 does not "push" the user out of the chair 1, but nevertheless restores the backrest 3. The insertion forces F1 and F2, as is generally the case with springs, increase slightly over the adjustment path. Accordingly, the extension force F3 also decreases slightly over the adjustment path.

Sinnvollerweise wird die Federkennlinie (Fig. 3) der Gasdruckfeder 13 so gewählt, dass die Kräfte F1 , F2 und F3 für normal gewichtige Personen zutreffend sind, d.h. diese müssen einen geringen zusätzlichen Druck durch Abstützen aufbringen, um die Rückenlehne nach hinten zu neigen. Selbstverständlich kann die Gasdruckfeder auch so gewählt werden, dass sich der Sessel 1 für schwergewichtige Personen eignet.It makes sense that the spring characteristic (FIG. 3) of the gas spring 13 be chosen so that the forces F1, F2 and F3 are suitable for persons of normal weight, i.e., for a person of normal weight. these must apply a slight additional pressure by supporting to tilt the backrest to the rear. Of course, the gas spring can also be chosen so that the chair 1 is suitable for heavyweight persons.

Der Sessel 1 ist also derart ausgestaltet, dass die Verstellung der Neigung der Rückenlehne 3 stufenlos ohne Betätigungsmittel erfolgt. Zusätzlich ist die Verstellung der Neigung derart ausgestaltet, dass die Rückenlehne 3 in beliebigen Stellungen gehalten werden kann. Dabei funktioniert die Verstellung der Neigung der Rückenleh- ne 3 vollständig ohne Betätigungsmittel, wie Hebel usw., und ohne Arretier- oderThe chair 1 is thus configured such that the adjustment of the inclination of the backrest 3 is continuously without actuating means. In addition, the adjustment of the inclination is designed such that the backrest 3 can be held in any position. In this case, the adjustment of the inclination of the backrest 3 completely works without actuating means, such as levers, etc., and without locking or

Rastmittel. Die Bedienung ist daher besonders einfach, weil nämlich keine besondere Bedienung notwendig ist. Somit ist die Verstellung intuitiv und bedarf keiner Erläuterung. Zudem wird der Aufbau des Sessels 1 vereinfacht, was zu einer Kosteneinsparung bei der Herstellung führt und diesen zudem robuster und wartungsfreundlicher macht. Latching means. The operation is therefore particularly simple, because no special operation is necessary. Thus, the adjustment is intuitive and needs no explanation. In addition, the structure of the chair 1 is simplified, which leads to cost savings in manufacturing and also makes this more robust and easy to maintain.
