Abstract
Stuhl, insbesondere Bürostuhl, mit einer zwischen der Sitzfläche (14) des Stuhls und der Rückenlehne (10) des Stuhls wirkenden Mechanik, durch die der Neigungswiderstand der Rückenlehne (10) in Abhängigkeit von der Belastung der Sitzfläche (14) durch den Benutzer steht. Die Sitzfläche (14) wird in Abhängigkeit von der Belastung der Rückenlehne (10) wenigstens teilweise angehoben, dadurch gekennzeichnet, dass die Mechanik eine Wölbung der elastisch verformbar ausgebildeten Sitzfläche nach oben bewirkt. Diese Wölbung sorgt dafür, dass der Benutzer angehoben wird. Der hier vorgeschlagene Stuhl kann stapelbar ausgebildet werden. Die Mechanik besteht aus nur wenigen Teilen und beansprucht keine zusätzliche Höhe. Chair, in particular office chair, with a mechanism acting between the seat surface (14) of the chair and the backrest (10) of the chair, by which the inclination resistance of the backrest (10) is dependent on the loading of the seat surface (14) by the user. The seat surface (14) is at least partially raised as a function of the load of the backrest (10), characterized in that the mechanism causes a curvature of the elastically deformable seat surface upwards. This curvature ensures that the user is lifted. The chair proposed here can be made stackable. The mechanics consists of only a few parts and does not require additional height.
Description
Die Erfindung betrifft einen Stuhl, insbesondere einen Bürostuhl, mit einer zwischen der Sitzfläche des Stuhls und der Rückenlehne des Stuhls wirkenden Mechanik, durch die der Neigungswiderstand der Rückenlehne in Abhängigkeit von der Belastung der Sitzfläche durch den Benutzer steht. Die Sitzfläche wird in Abhängigkeit von der Belastung der Rückenlehne wenigstens teilweise angehoben.The invention relates to a chair, in particular an office chair, with a mechanism acting between the seat of the chair and the backrest of the chair, through which the inclination resistance of the backrest is dependent on the load of the seat by the user. The seat is at least partially raised depending on the load on the backrest.
Derartige Stühle, bei denen die Kraft, mit der der Benutzer die Sitzfläche belastet, auf die Lehne übertragen wird, ist aus verschiedenen Patentschriften bekannt. (
Bei diesen wird die Kraftübertragung durch eine relativ aufwendige Mechanik bewirkt, die zudem meist einen zusätzlichen Kraftspeicher, wie zum Beispiel eine Feder benötigt.In these, the power transmission is effected by a relatively complicated mechanism, which also usually requires an additional power storage, such as a spring.
Der Erfindung liegt damit die Aufgabe zugrunde, einen Stuhl der eingangs genannten Art vorzuschlagen, dessen Mechanik einfach ausgebildet ist und ohne zusätzlichen Kraftspeicher auskommt.The invention is therefore based on the object to propose a chair of the type mentioned, whose mechanics is simple and does not require additional energy storage.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Mechanik eine Wölbung der elastisch verformbar ausgebildeten Sitzfläche nach oben bewirkt. Diese Wölbung sorgt dafür, dass bei Belastung der Rückenlehne der Benutzer angehoben wird.According to the invention this object is achieved in that the mechanism causes a curvature of the elastically deformable seat formed upwards. This curvature ensures that the user is lifted when the backrest is loaded.
Die Unteransprüche geben bevorzugte Ausgestaltungen an.The dependent claims indicate preferred embodiments.
Die Erfindung wird im Folgenden anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeipiels erläutert.The invention will be explained below with reference to a preferred exemplary embodiment illustrated in the drawing.
Dabei zeigt:
-
1 eine schematische Ansicht des Stuhl in einer Seitenansicht bei Nichtbelastung der Rückenlehne. -
2 eine schematische Ansicht des Stuhl in einer Seitenansicht bei Belastung der Rückenlehne. -
3 eine schematische Ansicht des Stuhl in einer Frontansicht bei Nichtbelastung der Rückenlehne. -
4 eine schematische Ansicht des Stuhl in einer Frontansicht bei Belastung der Rückenlehne.
-
