   Zwei Ausführungsformen sind in der beigefügten schematischen Zeichnung veranschaulicht, u. zw. sind die Fig. 1 und 2 je ein senkrechter Schnitt durch den Rahmen mit   Ansiehtsdarstellung   von Gurt, Zugfedern und Biegungsfeder.

   Damit bei erhöhtem Druck auf die Bespannung der Widerstand der Biegungsfeder rascher   wächst,   als der Federung des Systems an sich entspricht, ist gemäss Fig. 1 der Biegungsfeder eine   Abwälzfläehe   d zugeordnet. Die Abwälzfläehe kann entweder am eigentlichen Rahmen c sich befinden (Fig. 1) oder sie kann einem besonderen Stützorgan e zugehören (Fig.   2).   Letzteres kann an seinem dem Polster zugehörigen Ende entweder festgemacht sein oder, wie Fig. 2 zeigt, beweglieh sein. Diese Beweglichkeit kann gemäss Fig. 2 begrenzt werden derart, dass nach einer gewissen Durchbiegung das bewegliche Ende des

 load direction bend come to rest on rolling pads in such a way that the unsupported length of the springs is shortened the more they are loaded.



   Two embodiments are illustrated in the accompanying schematic drawing, u. between FIGS. 1 and 2 are each a vertical section through the frame with a view of the belt, tension springs and bending spring.



   The actual carrying tape, of which as many as desired can be used, consists of the

   Bending springs f.



   In order that, with increased pressure on the covering, the resistance of the flexure spring grows faster than the suspension of the system itself corresponds, a rolling surface d is assigned to the flexure spring according to FIG. The rolling surface can either be located on the actual frame c (FIG. 1) or it can belong to a special support member e (FIG. 2). The latter can either be fixed at its end associated with the cushion or, as shown in FIG. 2, be movable. This mobility can be limited according to FIG. 2 such that after a certain deflection the movable end of the
