Seating furniture made of foam with a frame consisting of rigid and deformable, but non-stretchable parts

The present invention relates to seating, such as armchairs, sofas and the like. In pressed foam, which is of a partially rigid and partially formed from deformable, non-stretchable materials frame is supported, wherein the deformable parts are attached to the rigid parts.

The main purpose of the invention is to obtain seating furniture and in particular armchairs, sofas and the like, the parts of which, on which the body rests and which must therefore be sprung and deformable, have a deformability with adaptation properties to the local pressure, without being expandable

to be. In this way a general becomes the greatest *

Convenience of adjustment achieved without the

Material is caused to elongate or expand.

In addition, another purpose is achieved and that the easy breakage of the foam is prevented, the -like is known - tends to break easily by itself, which is particularly the case in the frequently stressed areas.

The seating furniture consists of a semi-rigid composite carrier for the cover of the foam. This carrier exists from a partially ^! rigid frame and includes rigid Support parts and first deformable parts fixedly connected to the rigid parts; possible tubular or other shapes Deformable, non-stretchable parts also firmly connected to the rigid parts; second flexible parts with load-bearing capacity different from the first flexible parts, preferably in contact with the aforesaid first flexible parts are arranged; a foam cover, in which said frame is used and yields to deformations when in use, the stiff ones Parts of the frame are attached to the other fixed parts of the chair or even the main frame of the chair "form.

In order to make the armchair or sofa particularly comfortable, it was considered useful to use the deformable Part that can be made of different materials, a flexible part with different load capacity combine to make some parts of the pressed piece

to give a different load-bearing capacity and strength. The flexible part can be made of different materials such as Compressed or block polyurethane, polyether and polyester, latex or foam rubber, foam polyethylene or one of them another flexible elastomer commonly used for upholstery. The strength of what belongs to the frame Part of it can be different from or the same as the foam, but the load-bearing capacity is selected in such a way that that the effect of desired convenience is obtained. The part belonging to the frame is different Load-bearing capacity is applied to the stretchable insert at a specific point exposed to the stress and can be completely embedded in the outer polyurethane foam or protrude on one surface of the mold »

This precaution is of particular interest for pressed pieces, e.g. monolithic armchairs, in which a difference between the carrying capacity of the seat and that of the backrest or any other pressed piece of the same properties is required.

The attached drawing shows some exemplary embodiments of frame and carrier for foam body of the above type, namely show:

The frame 6 ¹ , however, is the support of the entire armchair, to which the feet or a base can be attached below. The same applies to the examples according to FIGS. 4 and 5. The rigid parts can be made of metal, wood or other material which ensures the rigidity and the unchangeability of the shape. To the

8 provided. These bets can come from a number of different things Material such as fabric, net, mesh, strips, tape, grid, so be made of any material, but that must never be elastic or deformable. As can be seen from Figures 2 and 3, the Inserts arranged so that they are the load-bearing core for form the foam surrounding them.

Depending on the strength of these flexible inserts 8 and the entire frame shape, the inserts 8, as shown in Fig. 4, freely or by a deformable, also at the ends of the rigid part 6 attached tube 9 (Fig. 5) to be attached to the frame and the rest line Follow. Of course, the tube 9 is also deformable, but not extendable.

Furthermore, a particularly effective softness was studied, but without fatigue of the material, from which the panel 11 of the chair is made is to cause. After long, in-depth attempts, the first deformable inserts 8 des Frame to lay a second flexible insert 10 of different load capacity, so that theoe different combined with that of the flexible part 8

Carrying capacity a really new effect in some places of the armchair or sofa that the human Taking up the body and supporting it, was created without the slightest fatigue of the bypassing Foam plastic.

Taking into account the essential properties of the present invention, it goes without saying that there are innumerable uses and types that lead to those uses; therefore they belong in the Scope of the present invention.
