Description

Die Erfindung betrifft eine Bespannung für Sitz- und Rückenlehnen von Sitzmöbeln, die aus federnden, aus Bändern und Federn zusammengesetzten Gurten besteht. Gegenüber bereits bekannt gewordenen Anordnungen dieser Art ist gemäß der Erfindung erreicht, daß die Bespannung, statt wie bisher in der Nähe des Rahmens immer weniger nachgiebig zu werden, auch dort gut federt ίο und der Polsterrahmen sich somit nicht unangenehm bemerkbar macht. Zu diesem Zweck sind gemäß der Erfindung die Gurte an Biegungsfedern aufgehängt, die so am Rahmen des Sitzmöbels befestigt sind, daß sie in der Belastungsrichtung sich durchbiegend auf- Abwälzunterlagen zur Auflage kommen, derart, daß die frei tragende Länge der Federn um so mehr verkürzt wird, je stärker sie belastet werden.The invention relates to a covering for seat and backrests of seating furniture that consists of resilient belts composed of ribbons and feathers. Opposite to already known arrangements of this type is achieved according to the invention, that the covering, instead of becoming less and less flexible in the vicinity of the frame as before, also springs well there ίο and the upholstery frame is not uncomfortably noticeable. To this Purpose are suspended according to the invention, the belts on flexure springs, the so on The frame of the chair is attached so that it sags in the direction of load on rolling pads come to rest in such a way that the cantilevered length of the springs the more it is shortened, the more it is loaded.

Zwei Ausführungsformen der Erfindung sind in der Zeichnung veranschaulicht, und zwar zeigenTwo embodiments of the invention are illustrated in the drawing, and although show

Fig. ι und 2 je einen senkrechten Schnitt durch den Rahmen mit Ansichtsdarstellung von Gurt, Zugfeder und Biegungsfeder.Fig. Ι and 2 each show a vertical section through the frame with a view of belt, tension spring and bending spring.

Die Bespannung besteht aus Gurten a, beispielsweise aus Metall, Stahl o. dgl., den Zugfedern b und den am Rahmen c befestigten B iegungs federn f. The covering consists of belts a, for example made of metal, steel o. The like., The tension springs b and the flexure springs f attached to the frame c.

Damit bei zunehmendem Druck auf die Bespannung der Widerstand der Biegungsfeder wächst, ist gemäß Fig. 1 der Biegungsfeder eine Abwälzfläche d zugeordnet. Die Abwälzfläche kann sich entweder am eigentlichen Rahmen c befinden (Fig. 1), oder sie kann einer besonderen Stützfeder e zugehören (Fig. 2). Diese Stützfeder kann an ihrem dem Polster zugewandten Ende entweder festgemacht oder, wie Fig. 2 zeigt, nachgiebig sein. Diese Nachgiebigkeit kann gemäß Fig. 2 begrenzt werden, derart, daß nach einer gewissen Durchbiegung das nachgiebige Ende des Stützorgans e sich gegen den Rahmen anlegt.So that the resistance of the flexure spring increases with increasing pressure on the covering, a rolling surface d is assigned to the flexure spring according to FIG. 1. The rolling surface can either be located on the actual frame c (Fig. 1), or it can belong to a special support spring e (Fig. 2). This support spring can either be fastened at its end facing the cushion or, as FIG. 2 shows, be flexible. This flexibility can be limited according to FIG. 2, such that after a certain deflection the flexible end of the support member e rests against the frame.
