Description
Die Erfindung betrifft eine Rückenlehne für einen Bürostuhl mit einer Tragstruktur, an der ein Rückenlehnenschalenelement befestigbar ist.The invention relates to a backrest for an office chair with a support structure to which a backrest shell element can be fastened.
Aus der
Ein solcher Bürostuhl ist besonders dafür geeignet, einen Benutzer darin zu unterstützen, seine Sitzposition hin und wieder zu ändern, sodass Rückenbeschwerden möglichst vermieden werden.Such an office chair is particularly suitable for assisting a user in changing his sitting position from time to time, so that back pain is avoided as much as possible.
Aufgabe der vorliegenden Erfindung ist es, den Bürostuhl dahingehend weiterzubilden, dass nicht nur das Zusammenspiel von Sitzfläche und Rückenlehne einen Benutzer zu "bewegtem Sitzen" anregt, sondern dass auch noch eine weitere Flexibilität bezüglich des Einnehmens unterschiedlicher Sitzpositionen besteht.Object of the present invention is to develop the office chair to the effect that not only the interaction of seat and backrest a user to "moving seats" stimulates, but that there is also a further flexibility in terms of taking different seating positions.
Gelöst wird diese Aufgabe erfindungsgemäß durch eine Rückenlehne für einen Bürostuhl mit einer Tragstruktur, an der ein Rückenlehnenschalenelement befestigbar ist, wobei die Tragstruktur zwei Streben aufweist, die an ihrem oberen und unteren Endbereich miteinander verbunden sind und zwischen den Endbereichen voneinander beabstandet sind, wobei die Streben zumindest in Abschnitten relativ zueinander bewegbar sind. Durch diese Ausgestaltung der Tragstruktur der Rückenlehne ergibt sich eine Flexibilität der Rückenlehne, sodass diese sich Bewegungen und Sitzpositionsänderungen eines Benutzers anpasst. Dennoch wird der Rücken eines Benutzers optimal unterstützt.This object is achieved according to the invention by a backrest for an office chair with a support structure to which a backrest shell element can be fastened, wherein the support structure comprises two struts which are interconnected at their upper and lower end region and spaced apart between the end regions, wherein the struts at least in sections are movable relative to each other. This configuration of the support structure of the backrest results in a flexibility of the backrest so that it adapts to movements and seat position changes of a user. Nevertheless, the back of a user is optimally supported.
Besonders bevorzugt ist es, wenn die Tragstruktur aus Kunststoff ausgebildet ist. Schon aufgrund der Materialeigenschaft ergibt sich so eine gewisse Flexibilität und Elastizität.It is particularly preferred if the support structure is made of plastic. Already due to the material property results in a certain flexibility and elasticity.
Besonders bevorzugt ist es, wenn die Tragstruktur Verbindungspunkte zur punktuellen Verbindung mit dem Rückenlehnenschalenelement aufweist. Insbesondere kann die Tragstruktur Öffnungen aufweisen, in die Verbindungselemente des Rückenlehnenschalenelements eingesteckt werden können. Die Verbindungspunkte können demnach so ausgebildet sein, dass eine Steckverbindung möglich ist. Wenn das Rückenlehnenschalenelement nur punktuell mit der Tragstruktur verbunden ist, werden auch geringfügige Relativbewegungen zwischen dem Rückenlehnenschalenelement und der Tragstruktur zugelassen, was eine weitere Flexibilität der Rückenlehne insgesamt mit sich bringt.It is particularly preferred if the support structure has connection points for punctiform connection with the backrest shell element. In particular, the support structure may have openings into which connection elements of the backrest shell element can be inserted. The connection points can therefore be designed so that a plug connection is possible. If the backrest shell element is only selectively connected to the support structure, even slight relative movements between the backrest shell element and the support structure are permitted, which brings about a further flexibility of the backrest as a whole.
Besonders bevorzugt ist es, wenn die Streben jeweils einen zumindest bereichsweise elastischen Lehnenschenkel aufweisen. Über den Lehnenschenkel können die Streben mit einem Basisträger verbunden sein. Durch den Lehnenschenkel kann eine weitere Elastizität der Rückenlehne bewirkt werden.It is particularly preferred if the struts each have an at least partially elastic backrest legs. About the back legs, the struts can be connected to a base support. By the backrest leg further elasticity of the backrest can be effected.
Gemäß einer Weiterbildung kann vorgesehen sein, dass der Lehnenschenkel c-förmig ausgebildet ist. Dadurch ergibt sich eine federnde Ausgestaltung des Lehnenschenkels.According to a development it can be provided that the backrest leg is C-shaped. This results in a resilient configuration of the backrest leg.
Vorzugsweise sind die Streben mit einem mit einem Fußgestell verbindbaren Basisträger verbunden. Der Basisträger kann dabei eine der Verbindungen in einem Endbereich der Streben darstellen. An dem Basisträger kann weiterhin eine Sitzstrebe angeordnet bzw. mit diesem verbunden sein.Preferably, the struts are connected to a connectable to a pedestal base support. The base support may represent one of the compounds in an end region of the struts. Furthermore, a seat stay can be arranged on or connected to the base support.
Die Streben können in einem ersten Abschnitt parallel zueinander ausgerichtet sein. Insbesondere können die Streben in einem Bereich des oberen Rückens parallel zueinander ausgerichtet sein. Zwischen den Streben kann eine Blende, insbesondere aus elastischem Kunststoff, vorgesehen sein.The struts may be aligned parallel to one another in a first section. In particular, the struts may be aligned in a region of the upper back parallel to each other. Between the struts, a diaphragm, in particular made of elastic plastic, can be provided.
Der Abstand der Streben kann sich in einem zweiten Abschnitt, insbesondere zu einem Basisträger hin, vergrößern. Der Abstand kann sich dabei kontinuierlich vergrößern. Alternativ ist es denkbar, dass sich der Abstand stufenförmig vergrößert. Auch können die Streben in diesem Bereich stabiler ausgebildet sein, um zu verhindern, dass die Rückenlehne im Bereich der Streben abknickt.The spacing of the struts may increase in a second section, in particular towards a base support. The distance can increase continuously. Alternatively, it is conceivable that the distance increases in steps. Also, the struts in this area can be made more stable in order to prevent the backrest from kinking in the region of the struts.
Die Rückenlehne kann ein mit der Tragstruktur verbundenes Rückenlehnenschalenelement aufweisen. Das Rückenschalenelement kann dabei so gestaltet sein, dass dieses eine weitere Flexibilität bietet und sich Bewegungen eines Benutzers anpasst. Das Rückenlehnenschalenelement kann auf die Tragstruktur aufgesteckt sein.The backrest may have a backrest shell element connected to the support structure. The back shell element can It should be designed in such a way that it offers further flexibility and adapts to a user's movements. The backrest shell element can be attached to the support structure.
Gemäß einer Ausführungsform kann vorgesehen sein, dass das Rückenlehnenschalenelement eine Vielzahl von Durchgangsöffnungen mit dazwischen angeordneten Stegen aufweist. Dadurch wird sichergestellt, dass das Rückenlehnenschalenelement nicht starr ist, sondern eine gewisse Flexibilität und Elastizität aufweist. Außerdem kann auf diese Art und Weise Material und Gewicht eingespart werden.According to one embodiment, it may be provided that the backrest shell element has a multiplicity of passage openings with webs arranged therebetween. This ensures that the backrest shell element is not rigid, but has a certain flexibility and elasticity. In addition, can be saved in this way material and weight.
Gemäß einer Weiterbildung kann vorgesehen sein, dass in vertikaler Richtung abwechselnd Durchgangsöffnungen mit einer ersten und mit einer zweiten, größeren Höhe angeordnet sind. Es wechseln sich somit Durchgangsöffnungen mit unterschiedlichen Höhen ab. Durch die Wahl der Höhe der Durchgangsöffnungen kann die Flexibilität und Elastizität des Rückenlehnenschalenelements eingestellt werden.According to a further development, provision can be made for passage openings having a first and a second, larger height to be arranged alternately in the vertical direction. It thus alternate through holes with different heights. By choosing the height of the through openings, the flexibility and elasticity of the backrest shell element can be adjusted.
Das Rückenlehnenschalenelement kann eine zentrale vertikale Reihe von Durchgangsöffnungen aufweisen, wobei jeder Durchgangsöffnung der zentralen vertikalen Reihe von Durchgangsöffnungen rechts und links eine schmalere Durchgangsöffnung zugeordnet ist. Somit sind in horizontaler Richtung gesehen zunächst eine schmale Durchgangsöffnung, dann eine breitere zentrale Durchgangsöffnung und anschließend wieder eine schmalere Durchgangsöffnung vorgesehen. So wird in einem zentralen Bereich eine größere Flexibilität erzielt als in einem neben dem zentralen Bereich gelegenen Bereich.The backrest shell element may have a central vertical row of through holes, each through hole of the central vertical row of through holes on the right and left being associated with a narrower through hole. Thus, seen in the horizontal direction, first a narrow passage opening, then a wider central passage opening and then again provided a narrower passage opening. Thus, greater flexibility is achieved in a central area than in an area adjacent to the central area.
Weiterhin kann vorgesehen sein, dass die Durchgangsöffnungen der zentralen Reihe von Durchgangsöffnungen von oben nach unten breiter werden. Dadurch wird bewirkt, dass das Rückenlehnenschalenelement in einem unteren Bereich, insbesondere im Bereich einer Lendenwirbelsäule eines Benutzers, eine größere Flexibilität aufweist als in einem darüber liegenden Bereich.Furthermore, it can be provided that the passage openings of the central row of passage openings are wider from top to bottom. This causes the backrest shell element in a lower region, in particular in the region of a user's lumbar spine, has greater flexibility than in an area located above it.
Weitere Vorteile ergeben sich, wenn schlitzartige Öffnungen vorgesehen sind. Schlitzartige Öffnungen können sich dabei nahezu über die gesamte Breite des Rückenlehnenschalenelements erstrecken. Es kann jedoch auch vorgesehen sein, dass mehrere schlitzartige Öffnungen in horizontaler Richtung vorgesehen sind. Durch die Anordnung und Länge der schlitzartigen Öffnungen kann eine weitere Einstellung der Eigenschaften des Rückenlehnenschalenelements erfolgen.Further advantages arise when slot-like openings are provided. Slot-like openings can extend almost over the entire width of the backrest shell element. However, it can also be provided that a plurality of slot-like openings are provided in the horizontal direction. Due to the arrangement and length of the slot-like openings, a further adjustment of the properties of the backrest shell element can take place.
Aus dem Vorstehenden ergibt sich, dass das Rückenlehnenschalenelement skelettartig aufgebaut sein kann, insbesondere mehrere Stege aufweisen kann, die voneinander durch Öffnungen beabstandet sind.From the above it follows that the backrest shell element can be constructed skeleton-like, in particular can have a plurality of webs, which are spaced from each other by openings.
An dem Rückenlehnenschalenelement können elastische Befestigungslaschen zur insbesondere lösbaren Befestigung an der Tragstruktur vorgesehen sein. Durch die Befestigungslaschen kann die punktuelle Verbindung des Rückenlehnenschalenelements an der Tragstruktur erfolgen. Dadurch, dass die Befestigungslaschen vorzugsweise elastisch sind, ist das Rückenlehnenschalenelement begrenzt relativ zur Tragstruktur bewegbar.On the backrest shell element elastic fastening straps can be provided for the particular releasable attachment to the support structure. By fastening straps, the selective connection of the backrest shell element can be made to the support structure. Because the fastening straps are preferably elastic, the backrest shell element is movable in a limited manner relative to the support structure.
