The innovation relates to the formation of an upholstery body in the form of cushions o, the like. made of elastic sponge material, which is composed of several layers.

. "," -ner retains edges .., '. . . "-. -; -

The previous upholstery bodies of the present type are subject to considerable deformation under load during their use subject to what follows from the fact that the side walls of the upholstery body a certain bend near the inside "are subjected to, which by the corresponding tensioning of the upholstery cover is effected, which is made of such - material * as, luch or artificial or natural leather be-- .. " it says that the usable area of the upholstery can yield within reasonable limits.

: For upholstery where: -the side walls are slightly ■>"." can-be shaped, the disadvantage arises that the coating in question often no longer retains its predetermined, precise sharp edges and that, in addition, the application of the coating - "is very difficult under these conditions" ■ .. -;

Such disadvantages are made possible by the present innovation from -, ..; ■ switched «;

,. · A goal of the innovation is directed towards the. Training one *.:.: 'Upholstery body of the type mentioned, which essentially consists of "

an elastic sponge material, for example, porous rubber made of latex ^: or porous polyurethane admits in multi-part or one-piece combination with additional elastic .Polsterwerkstoffe, as they are explained below and which are arranged in such a way that they exert their typical properties can, in order to achieve different properties of the desired type for the entire upholstery body, e.g. sufficient resistance to the mentioned deposits of the side walls, considerable softness, well-formed, sharp edges of the cover and at least one slight adjustment to it .the.tension. applied to the coating under load. ^r / .. ■ .---.

To achieve the stated goal, the innovation provides a layered upholstery body in the form of cushions or the like ^: made of foam material, which firmly with a fiber layer penetrates the foam material through the latter during the foaming of the upholstery body within a closed form is connected, and according to the firing, daäärch characterizes that the upholstery belt body is composed in a multi-part or one-piece combination of a main body and a separate outer cover layer each made of elastic Sehaummateriäi, which is insoluble in the. Pores: the surface of the cover layer facing the main body, during foaming within the closed form

penetrated foam material, of the main body are connected to one another, the part of the main body facing the cover layer being a layer of. rubberized fiber rsitoff ■ contains, ⁷ whose '"-" .. outline corresponds essentially to the course of the edges of the main body, and wherein, the exposed surface of the' cover layer 'forms the area of use of the upholstery body.

With. the elastic sponge material of the. main body overall .. ^r. filled: intermediate layer insert made of rubberized fiber material gives the upholstery the desired degree of rigidity due to the high flexural strength of this insert according to the type and combination of the materials used. By the presence · - be 'this intermediate layer insert deforms the padding body under load only in a normal manner, so that the respective Fberzüg only under slight tension is and not a ÄVbiegung of the side walls to the ^inside: ν enters ,: what · by. ; .the flexural strength of: inserted intermediate; layer is prevented. In addition, this intermediate, creates a -such. Tension of: cloth or natural covering. borrowed or artificial leather or the like. That its .Kanten remain unchanged in the intended and desired shape.

The outer cover layer made of elastic sponge material gives .. the porcelain body a certain surface softness, so that the feeling of a hard surface is eliminated, which ^:

'through the intermediate layer made of rubberized fiber. material could adjust. This outer cover layer can in particular .then, -if they. is made of porous polyurethane, too have a high permeability to air if its impermeable Outer skin is detached.

Further advantages of the new upholstery body result from an increased resistance to compression, so that a saving of raw material is possible and from an increased tensile strength. _:

The upholstery body discussed above can be particularly. advantageously be produced in a single molding process as follows « ■ "" ■ "";

First, a layer of elastic sponge material is applied the bottom of a corresponding to the dimensions of the upholstery body The mold is placed on top of this layer and a layer of rubberized fiber material is applied. The remaining part. ■ the mold is then made of an elastic material with the liquid foam; e.g. Latex foam filled and the shape e.g. by means of a cover part closed. At the Yersohliessen the Form then becomes, when it has been filled in to the correct extent is, this foam is forced into the interstices of the inlaid penetrate rubberized fiber layer through this Layer * to step back out on the "other side and in."
