The invention relates to a suspension for aich an öi'üa- or lying surface frame, which is made up of parallel arranged spring arches, the ends of which with it opposite frame strips are connected. the Suspension is preferably intended as a lower basic suspension for supporting cushions and the like. To-

here the individual spring bows with eyelets bent from the spring wire were lined up in 3 rows, which ran parallel to the frame strips, ΐ / emi at the known suspension breaks a spring arch, then the repair is very difficult to carry out, 7; eil more or less the entire I'ede_ tion must be expanded in order to. a feather bow too substitute. Also with the known suspensions an initial pulling effect exerted on the axillary strips, why one with a longer lying surface had to arrange solid supports between the stressed frame strips. Such supports make themselves but uncomfortable for the user when sitting or lying down: noticeable.

To replace a single spring bow easily and individually. can and about the tensile stress To avoid in the frame is proposed according to the invention, each one with the bow of the feather

one bent at an angle and the frame strip parallel piece in a horizontal hat the avenging bar intervenes, Sin mentioned opposite The spring end piece, bent again at an angle, engages in a hole in the cream strip a; in addition, all feather arches are at the top through at least one perpendicular to them Connected tube, in which each spring bow detachably engages.

With the new suspension, each spring bow can be retrofitted can easily be detached from your connecting tube, whereupon you can simply pull it out of the frame can be pulled out, more than simply a new spring bow has to be installed again.

The "releasable" connection of the tube with the spring bow can be done in a suitable way, preferably the spring arcs are in transverse

Pipe slots, whereby they are through one or more, wires that can be pushed into the pipe are secured. This fuse can be easily moved or pulling out the safety wire - can simply be lifted *

The drawing shows an exemplary embodiment of the suspension.

Figure 1 shows a frame piece with built-in suspension, partially shown in a horizontal longitudinal section through a frame strip,

Figure 2 is a cross-section along the line II-II of the figure 1, - -

Figure 3 shows a larger-scale, drawn longitudinal section through the connecting pipe along the line III - III of Figure Λ,

The opposite frame strips 1 of a preferably made of wood ". Frames are inside with a horizontally continuous groove 2 and provided with holes 3 extending from the hat 2, which correspond to the distance between the existing parallel spring arcs 4.

The individual spring bow 4 made of steel wire can be formed into loops 4-V in a manner known per se and also be bent to closed eyelets. Of the Spring wire is bent at an angle once at each end, so that one of the frame strips 1. lying parallel Piece 5 is formed. This piece of leather goes into the with another angled turn End piece 5 'across.

During assembly, the spring end pieces 5 'i the corresponding holes J of the frame strips T inserted, the spring pieces 5 in the hats

engage the frame strips. This is for one Stability of the individual spring bow 4 ensured.

In the example shown, the parallel spring arcs 4 are at the top and in the middle of the suspension connected to one another by a pipe 6. This is preferably made of thermoplastic plastic existing tube 2 is provided with a number of transverse slots 7 corresponding to the spacing of the spring arches Mistake. As FIG. 3 shows, the spring arches 4 engage in the transverse slots 7. This situation of intervention must be secured in some suitable way. In the example shown, the backup takes place by a wire 8 inserted inside the tube 6 in such a way that it prevents the emergence of the spring bow 4 .from the pipe cross slot 7 prevented. The safety wire 8 is preferably bent over at one end or to that in FIG. 3 shown eyelet 8 'bent to a handle

form. In the tube 6, further cutouts 9 are provided at the corresponding points which the fuse wire 8 is inserted and can also be pulled out.

Preferably, a plurality of such safety wires 8 lie next to one another in the longitudinal direction of the tube 6. The tube 6 can extend in one piece over the entire width of the suspension, it can but also individual pieces of pipe 6 may be present, as shown in the drawing.

If you pull the safety wire out completely or partially at the corresponding point on the tube 6, a leather sheet 4 in need of replacement can easily be removed from the tube 6 and also with its end pieces 5 ₅ 5 ¹ pulled out of the frame strips.

In place of the Kohres 6 can of course another suitable connecting element. Am made of elastic material "existing connecting element has the advantage that it deforms when the suspension is loaded.

It should be mentioned that the suspension is perfect is installed tension-free between the frame strips, so that neither train nor pressure on the Framework, is exercised. Also could-the single spring be made of strip steel.

Claims (2)

claims 1. Suspension for a seat or lying surface frame with spring arches arranged in parallel, the ends of which are connected to the frame strips ", characterized in that each spring end with an angularly bent piece (5) parallel to the frame strip (1) lies in a horizontal groove ( 2) and with a further bent end piece (5 ¹ ) engages in a hole (3) in the frame strip and that the spring arches (4) are connected at the top by at least one tube (6) running transversely to the inside, in which each spring arch is detachable intervenes. 2. Suspension according to claim 1, characterized in that that those in pipe slots. (7) lying spring arcs by one or more retractable spring arcs Wires (8) are secured.
