Abstract

The backrest has back shells (L) held by rubber elements (G). The rubber elements are provided diagonally upward in its longitudinal direction. The shells are attached in a resting position. The shells have a distance of 6 to 8 centimeter.

Description

Im deutschen Patent 19780060 vom 12.2.97 wird eine Rückenlehne beschrieben, die aus zwei senkrechten Schalen L besteht, die durch Gummielemente G gern 3 so an einer Querschiene 120 befestigt sind, dass der Rücken beim Zurücklehnen leicht angehoben wird, was zur Entlastung des unteren Teils der Wirbelsäule führt. Diese Gummielemente sind dort gem 1 in ihrer Längsrichtung senkrecht an den Rückenschalen befestigt.in the German Patent 19780060 from 12.2.97 a backrest is described, which consists of two vertical shells L, which like rubber elements G 3 so on a cross rail 120 are fastened, that the back is raised slightly when leaning back, which leads to the relief of the lower part of the spine. These rubber elements are gem 1 attached in its longitudinal direction perpendicular to the back shells.

Erfindungsgemäß sind in einer neuen Ausführung diese Gummielemente G nach 2 in ihrer Längsrichtung nach oben außen an den Rückenschalen befestigt. Der Lendembereich wird dadurch wirksamer entlastet, da sich die Schalen L beim Gegenlehnen um die Achsen A drehen und so den unteren Teil der Hüfte besser umfassen. – Außerdem werden die Schalen L gem. 4 so an die gebogene Querschiene 120 angesetzt, dass sie etwa 20° nach innen zeigen, was zusätzlich zum Umfassen und Stützen im Lendenbereich führt. Eine Vergrößerung des Abstandes der Schalen L auf etwa 8 cm und ein sehr kleiner Abstand der Lehnen zum Sitz führen zu weiterer Verbesserung.According to the rubber elements G are in a new version after 2 attached in its longitudinal direction upwards to the back shells. The lumbar region is thereby relieved more effectively, since the shells L rotate counter-steer around the axes A and so better embrace the lower part of the hip. - In addition, the shells L gem. 4 so to the curved cross rail 120 Assuming that they point about 20 ° inwards, which in addition leads to encompassing and supporting the lumbar region. An increase in the distance of the shells L to about 8 cm and a very small distance of the backrest to the seat lead to further improvement.
