Definitions

  • the invention is directed to an upholstered part of the type specified in the preamble of claim 1.
  • Such an upholstered part can be manufactured on its own and later used in the case of use as a support for a piece of seating or reclining furniture.
  • Such a pad is then either connectable to the furniture or removable from it.
  • the cover fabric envelops the upholstery on both sides.
  • such a cushion part can also be firmly connected to the seating or reclining furniture intended for this purpose.
  • the cover fabric then only spans the front side of this unit and is connected to the furniture at the edge.
  • the known upholstery part which can partly be found in DE-A-3 007 343, generally has a multi-layer filling. Over a core layer made of foam, which is responsible for the elasticity of the upholstered molded part, an upper and lower layer made of a non-woven fabric is placed, which together with the core layer produce the filling of the upholstered part and over which a layer of the cover material is then arranged on the top and bottom .
  • the two layers of upholstery fabric are joined together by sewing along the outline of the filling. In order to prevent the covering material from slipping on its filling, the two layers of covering material are sewn at points through the filling and the sewing points are reinforced with buttons.
  • a similar procedure is used for upholstered parts that are integrated with the seating or reclining furniture, except that the view side manages with a layer of cover fabric that is connected to the furniture around the edges by gluing, stitching or nailing.
  • the manufacture, storage and processing of the various layers The filling and the covering with the cover fabric are cumbersome and require difficult logistics.
  • the upholstery physiology of the known product is unsatisfactory because when the upholstered part is used as intended, the pores in the foam close due to the body weight and lead to poor ventilation.
  • the layers of the filling diverge too easily when in use and do not give the body sufficient lateral support.
  • the resilience of the molded part only results in a corresponding elastic change in the volume of the filling, while the covering material above it is not affected and therefore wrinkles.
  • the invention has for its object to develop a simple and inexpensive to produce molded part of the type mentioned in the preamble of claim 1, which remains dimensionally stable even after prolonged use, provides good support for the body, is easy to clean and can be plumped by a wrinkle-free Distinguished course of the upholstery fabric.
  • This is achieved according to the invention by the special structure stated in the characterizing part of claim 1, which is based on the following:
  • the invention uses a uniform filling made of a special voluminous nonwoven fabric which consists of thermofusible binding fibers.
  • binding fibers are known as so-called core sheath fibers, the sheath material of which on the one hand leads to a reciprocal connection of the fibers in the filling under the action of heat and therefore provides a shape-elastic product called "nonwoven fabric".
  • this special nonwoven fabric is pressed together with the cover fabric to create a relief that creates the desired, ergonomic seating or lying surface.
  • the binding fibers also create a firm bond between the cover fabric and this special filling and freeze the relief after the various points of contact have solidified.
  • a modular upholstery molded part which forms a firm connection both between the fibers in the nonwoven fabric deformed according to the relief profile and with the cover fabric placed thereover.
  • the upholstered molded part is therefore stiffened to fit the body, but has an ideal resilience in terms of shape in the voluminous areas of its relief.
  • the cover material For the production of the upholstered molded part according to the invention, therefore, only two materials are required, namely, in addition to the cover material, a voluminous nonwoven fabric of uniform construction integrated with it.
  • the dimensional stability results from a large number of bonding points within the nonwoven fabric and between the nonwoven fabric and the cover fabric. Both materials are fixed to each other vertically and horizontally according to the relief profile.
  • the customization required in the known upholstery part is eliminated. It this results in easy cleaning of the soiled upholstery molding according to the invention because the water content of such a product is low.
  • the fibers in the nonwoven are connected to each other only at the points of contact and preferably consist of rigid fibers, according to claim 4, which are bent like a whip according to the respective relief contour and therefore justify the already mentioned ideal elasticity of form, which also provides lateral support for the body.
  • This airy structure of the filling is physiologically favorable in terms of cushioning, as there is a good exchange of heat and moisture. Folding or shifting of the cover fabric on the filling is impossible due to the mutual connection of the relief to the binding fibers.
  • nonwoven fabric only partially from binding fibers which are combined to form a homogeneous mixture with normal fibers, because the thermofusibility of the binding fibers simultaneously establishes a corresponding definition of the intermediate normal fibers.
  • a proportion of the binding fibers in the mixture of between 15 and 40% has proven useful.
  • a stiffening zone can be created in the upholstery molding according to the invention, which consists of the same material. This can be designed punctually without the need to use further fastening means, such as seams, buttons, rivets or the like.
  • Such stiffening zones not only serve as an ornament, but also contribute significantly to the solidification of the relief in the upholstered molded article after Invention at. This applies above all to zones of this type which are of linear design because, as claimed in claim 6, these form stiffening webs. According to claim 7, these can reinforce the contour edge of the upholstery molding and thereby ensure the dimensional stability of the product according to the invention, including the cover material.
  • stiffening webs can also, as is apparent from claim 8, determine buckling edges in the upholstered molded part, which there separate the two zones between the seat surface on the one hand and the backrest on the other hand. If the stiffening circumferential frame mentioned is also used in the upholstery molding, one should, as is apparent from claim 9, provide cutouts at the transition points in the edge region of the product according to the invention. Openings according to claim 10 can also be used for decoration and as functional means for fastening the upholstery molding.
  • the stiffening zones mentioned are completely sufficient to produce the desired dimensional stability in the product according to the invention.
  • inserts made of a material of a different type, such as metallic support structures can also be integrated in the special binding fiber nonwoven fabric of the molded cushion part according to the invention.
  • thermoplastic binders like a sprinkled powder made of thermoplastic material.
  • the invention is also directed to a method for producing such an upholstered molded part, as can be seen, for example, in part in DE-A-3 007 343, the various of which Method steps result from the characterizing part of claim 13. If one then assumes flexible fibers from a mixture of binding fibers and normal fibers, for which the material combination polyester-copolyester is recommended, a thorough mixing of these fiber components is important in order to obtain a really homogeneous non-woven fabric which can only be obtained by hot air, such as has already been mentioned, at the various points of contact within the nonwoven creates firm connections that lead to the voluminous nonwoven.
  • This non-woven fabric is then combined with the cover fabric and compressed in an air-permeable form to the desired relief, after which hot air leads to a softening of the previous connections of the fibers, but at the same time wetting the softened material with the further contact points between the fibers, which are then caused by relief the upholstery on the other hand.
  • This combination of materials is then cooled in the closed form, which freezes the relief in the upholstery material. Then you will conveniently trim the upholstery molding along its outline, whereby the product is already finished.
  • Thermoplastic binders according to claim 15 should be sprinkled on the outer surfaces of the nonwoven fabric before application of the cover, if necessary.
  • the upholstered molded part 10 consists of a profiled filling 11, which here is provided with a cover material 20 both on its front side 12 and on its rear side 13.
  • a uniform filling 11 of a special type, the appearance and properties of which can best be seen from FIGS. 3 and 4.
  • a non-woven fabric 14 which is formed from a homogeneous mixture of two fibers 15, 15 ', both of which consist of flexible material, but have a different structure.
  • One type of fiber are binding fibers 15, which are produced from a polyester core 17 and from a jacket 18 of copolyesters.
  • the other type consists of normal fibers 15 ', the material of which is polyester.
  • a mixture of 30% binding fibers 15 and 70% normal fibers 15 ' has proven very useful.
  • the proportion of binding fibers 15 can also vary in the range between 15 to 40%.
  • Both fibers 15, 15 'but should be the same system, for which polyester has been selected in the present case.
  • the fiber fleece 14 produced in this way, according to FIG. 3, has a weight per unit area of approx.
  • the structure of the binding fiber 15 is illustrated in FIG. 9 with its fiber cladding 18 enveloping the fiber core 17.
  • the nonwoven fabric 14 is such a homogeneous mixture that the fibers 15, 15 'alternate in each direction in their proportionate ratio of about 1: 2 and thus a binding fiber 15 always tangent or crosses normal fibers 15'.
  • Such contact points are designated 19 in the schematic illustration of FIG. 3.
  • this nonwoven fabric 14 is now penetrated by hot air, which is dimensioned in terms of temperature, air flow strength and flow duration so that the above-mentioned jacket material 18 of the binding fibers 15 softens and the mentioned contact points 19 wet and adhere to one another.
  • hot air which is dimensioned in terms of temperature, air flow strength and flow duration so that the above-mentioned jacket material 18 of the binding fibers 15 softens and the mentioned contact points 19 wet and adhere to one another.
  • the thickness of the fleece is reduced to the dimension 26 and thereby the points of contact 19 between the fibers 15, 15 'are more pronounced or new.
  • the nonwoven fabric is now cooled, whereby the drop-shaped materials of the fiber jacket 18 solidify at the mentioned contact points and produce the connections 29 shown in FIG. 4 between the fibers 15, 15 '. This creates the special character of the product shown in FIG.
  • FIG. 4 a There are two pairs of fibers 15, 15 'interconnected by the core jacket material, each shown. The connections 29 between the fibers 15, 15 'hold them tight against each other and generate the elasticity that can be determined with this special nonwoven 24, which is noticeable when loads occur.
  • This nonwoven fabric 24 is now provided on its top and bottom, as shown in FIG. 5, with a cover fabric 20. It is readily possible to provide such a cover material 20 only on one side of the nonwoven fabric 24. If necessary, a thermoplastic binder 21 can additionally be sprinkled on the surface of the nonwoven in powder form.
  • This combination of fabrics 22 consisting of the outer cover fabric layers 20, 20 and the non-woven fabric 24 present as a central layer is now brought between the two halves 31, 32 of a mold 30 consisting of a sieve-shaped material and these mold halves 31, 32, as in FIG. 5 emerges, firmly pressed against each other in the sense of the indicated pressure arrows 33.
  • the mold halves 31, 32 designed as a sieve wall have a surface profile that determines a certain relief contour 34, which results from the intended use of the finished upholstered molded part 10 as a seat or lying surface.
  • the corresponding relief is formed not only in the upholstery fabric 20, but in the entire fabric combination 22 from FIG. 5.
  • the fibers in the nonwoven fabric 24 are also deformed accordingly, this deformation initially being elastically yielding and the two mold halves 31, 32 therefore being held firmly against one another in order to emboss the relief 34 in the fabric combination 22.
  • the fibers 15, 15 'involved are bent like a whip and penetrate into one another in accordance with the compression determined by the profile contour at the respective point. This is based on the previously explained in Fig. 4 a two fiber pairs 15, 15 'in Fig. 6 a, where there are further points of contact 28 between the fiber pairs 15, 15' and of course points of contact 27 between the nonwoven fabric 24 and the Cover fabric 20 result.
  • hot air 23 is sent through the material combination 22 clamped in the mold 30, namely, transversely to the fabric layers, through the sieve holes of the mold halves 31, 32. Amperage and flow duration so dimensioned that the connections 29 explained above with reference to FIG. 4 between the fibers 15, 15 'soften again, but additionally also at the mentioned further contact points 27, 28 of FIG. 6 a the jacket material of the binding fibers 15 softens and there is a corresponding wetting. This also applies to the surface-sprinkled thermoplastic binder 21 of FIG. 5. Once this has been done, the mold 30 remains pressed together and is exposed to a cold air flow 25, which will be explained in more detail with reference to FIG.
  • the embossed relief 34 is frozen in this way in the upholstery molding 10, which is why this shape is retained if, as can be seen from FIG. 6, the two mold halves 31, 32 are then removed.
  • the cover fabric 20 is stretched tightly over the relief-like surface of the nonwoven fabric 24 and is permanently connected to it.
  • the relief structure 34 of the surface sits like a grain in the interior of the nonwoven 24 continues and is fixed there by a corresponding mutual anchoring of the fibers 15, 15 '. As a result, the relief is embossed on all layers of the material combination 22.
  • FIGS. 1 and 2 How such a relief 34 according to FIG. 6 can look in a finished upholstered molded part is shown in FIGS. 1 and 2.

  • Compressed points are formed at 36 in the backrest area 41, both on the face side and on the back side 12, 13 with the inclusion of the respective cover material 20, which is why there is a crater-shaped relief there.
  • button-shaped impressions 36 which are sewn in Buttons work, although these points are made of the material of the material combination 22 due to extreme compression and caking when the hot air 23 is carried out.
  • webs 38 stiffening at the edge have been created, which produce a circumferential frame made of the same material here.
  • These webs 38 thus form a frame that runs all around the edge, which, although it remains elastically bendable, stiffens the outline shape of the product 10 permanently. In order not to impair the ability to bend at the bend edge due to the frame webs 38, this is provided in the end regions with a wedge-shaped incision 39 which interrupts the peripheral frame at this point.
  • the seat area 40 has a profile of its relief that is adapted to the body shape in use. Specifically, on the front side 20 of the upholstered molded part 10, a wide beaded edge 43 accompanies the frame webs 38 and delimits an essentially flat central region 44 which, when used as intended, serves for the buttocks surface of the body. The bulge 43 creates a sloping slope with respect to this central region 44, which leads to a dimensionally stable lateral support of the human body. It goes without saying that any other body-appropriate profiling could be provided in the molded cushion part 10 on one or both sides 12, 13.
  • Breakthroughs that are useful, for example, for the assembly of the upholstered molded part on a piece of seating furniture can also be produced by punched-out areas that can be reinforced on the edges by similar impressions 36.
