Description

Die Erfindung betrifft eine Rückenlehne für einen Stuhl, Sessel oder dgl.The invention relates to a backrest for a chair, armchair or the like.

Aus der DE 90 063 16 U1 ist eine Rückenlehne bekannt, die aus zwei senkrecht angeordneten Rückenschalen L besteht, die durch Gummielemente so an einer Querschiene 120 eines Rückenlehnenträgers befestigt sind, dass der Rücken einer Person beim Zurücklehnen leicht angehoben wird, was zur Entlastung des unteren Teils der Wirbelsäule führt. Die Gummielemente sind in ihrer Längsrichtung senkrecht an den Rückenschalen befestigt.From the DE 90 063 16 U1 is a backrest known, which consists of two vertically arranged back shells L, which by rubber elements so on a cross rail 120 a backrest support are attached, that the back of a person is slightly raised when leaning back, which leads to the relief of the lower part of the spine. The rubber elements are fixed in their longitudinal direction perpendicular to the back shells.

Diese Anordnung ist in den 1 und 3 dargestellt.This arrangement is in the 1 and 3 shown.

Eine solche Anordnung ist auch aus der US 7 278 688 B1 bekannt, wobei die Rückenschalen hier an einer gebogenen Querschiene des Rückenlehenträgers befestigt und dadurch nach innen auf eine sitzende Person zu gedreht sind.Such an arrangement is also from the US Pat. No. 7,278,688 B1 known, the back shells attached here to a curved crossbar of the backrest wearer and thereby turned inwards to a seated person.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Rückenlehne für einen Stuhl, Sessel oder dgl. zu schaffen, die den unteren Teil der Hüfte einer sitzenden Person besser umfasst und so den Lendenbereich wirksamer entlastet.Proceeding from this, the present invention seeks to provide a backrest for a chair, armchair or the like. Which better covers the lower part of the hip of a seated person and thus relieves the lumbar area more effective.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Advantageous embodiments are specified in the subclaims.

Erfindungsgemäß sind die Gummielemente in ihrer Längsrichtung schräg nach oben außen zeigend an den Rückenschalen befestigt. So wird eine wirksamere Entlastung im Lendenbereich erreicht, da sich die Rückenschalen beim Gegenlehnen einer Person um die Längsachsen der Gummielemente drehen und dadurch der untere Teil der Schalen die Hüfte besser umfassen.According to the rubber elements in their longitudinal direction obliquely upward pointing out attached to the back shells. Thus, a more effective relief in the lumbar region is achieved, since the back shells rotate when the backrest of a person around the longitudinal axes of the rubber elements and thereby better cover the lower part of the shells of the hip.

Nach einer Ausgestaltung sind zur besseren Umschließung der Hüfte zudem die beiden Rückenschalen bereits in ihrer Ruhelage in Bezug auf die Sitzrichtung etwa 20° nach innen auf eine sitzende Person zu gedreht angebracht.According to one embodiment, for better enclosure of the hip, the two back shells are also mounted in their rest position with respect to the seat direction about 20 ° inwards to a seated person to rotate.

Weiterhin dient ein erweiterter horizontaler Abstand der Rückenschalen voneinander von 6 bis 7 cm der besseren Umschließung der Hüften.Furthermore, an extended horizontal distance of the back shells from each other from 6 to 7 cm of the better enclosure of the hips.

Dem gleichen Ziel gilt ein geringer Abstand von 1 bis 2 cm von der Unterkante der Rückenschalen zur Sitzfläche.The same goal is a small distance of 1 to 2 cm from the lower edge of the back shell to the seat.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert.The invention will be explained in more detail with reference to an embodiment with reference to the drawing.

Es zeigt:It shows:

Die Gummielemente (G) sind an den Rückenschalen (L) so befestigt, dass sie in ihrer Längsrichtung bzw. mit ihren Längsachsen A nach oben außen zeigen.In the 2 and 3 shown backrest has two each by rubber elements G on a cross member 120 a backrest support held backshells L on. The rubber elements (G) are attached to the back shells (L) so as to point upwards in their longitudinal direction or with their longitudinal axes A.

Gegenüber dem Stand der Technik ist eine Erweiterung des horizontalen Abstands der Rückenschalen von 6 bis 7 cm vorgesehen.Compared to the prior art, an extension of the horizontal distance of the back shells of 6 to 7 cm is provided.

Der Abstand der Unterkante der Rückenschalen L zu einer Sitzfläche beträgt 1 bis 2 cm.The distance of the lower edge of the back shells L to a seat surface is 1 to 2 cm.
