Description

Die Erfindung bezieht sich auf einen Polsterkörper gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a cushion body according to the preamble of the main claim.

Die zum Stand der Technik gehörenden und einen Schaumstoffkern verwendenden Polsterkörper werden seit etwa 1960 mit einem Wattevlies beschichtet, das üblicherweise aus Polyesterfasern besteht und in den Gewichtsklassen von etwa 40 bis etwa 1000 g/qm ge­fertigt und eingesetzt wird. Die Einsatzgebiete des Wattevlieses liegen schwerpunktmäßig im Bettwarenbe­reich, in der Polstermöbel- und Matratzenindustrie, in der Konfektion und im Spielzeugbereich, bei­spielsweise für Spieltiere.The upholstered bodies belonging to the prior art and using a foam core have been coated since about 1960 with a cotton fleece, which usually consists of polyester fibers and is manufactured and used in the weight classes from about 40 to about 1000 g / m 2. The areas of application of the cotton fleece are mainly in the bedding area, in the upholstery and mattress industry, in the confection and in the toy area, for example for toys.

Das Wattevlies erfüllt seine Funktion dort, wo die so ausgerüsteten Polsterkörper nicht mit Druck und Feuchtigkeit belastet werden. In dem Bereich, wo aber diese Belastungsfälle vorliegen, wie beispiels­weise bei Polsterkissen, Matratzen usw., erfüllen sie ihre Funktion nicht zufriedenstellend. Diese aufgebauschten, aus Polyesterfasern hergestellten Wattevliese dienen in der Regel zur Abdeckung der Schaumstoffkerne und sollen dem Polsterkörper eine bessere Optik verleihen und den direkten Kontakt zwischen dem eigentlichen Bezugsstoff, d.h. der Um­hüllung und dem Schaumstoffkern, verhindern.The cotton fleece fulfills its function where the upholstered body equipped in this way is not exposed to pressure and moisture. In the area where these stress cases are present, such as cushion cushions, mattresses, etc., they do not perform their function satisfactorily. These puffed up nonwovens made of polyester fibers are usually used to cover the foam cores and are intended to give the upholstered body a better look and direct contact prevent between the actual covering material, ie the covering and the foam core.

In den langen Jahren des Einsatzes derartiger Watte­vliese hat sich gezeigt, daß bei Sitz- und Liegekis­sen hier große Beanstandungen auftreten, da unter der Einwirkung des Druckes und der Körperwärme sowie der auftretenden Transpiration und der damit in das Wattevlies eingeführten Feuchtigkeit, das Wattevlies verdichtet wird und auf weniger als 1/3 seines ur­sprünglichen Volumens reduziert wird. Das führt einerseits aufgrund des dann auftretenden Faltenwur­fes zu Unansehnlichkeiten und Reklamationen, ande­rerseits erfüllt aber auch das Wattevlies nicht mehr die ihm zugedachte Aufgabe.In the long years of using such non-woven fabrics, it has been shown that there are great complaints with seat and lying cushions, since under the influence of pressure and body heat as well as the perspiration that occurs and the moisture that is introduced into the non-woven fabric, the non-woven fabric is compressed and is reduced to less than 1/3 of its original volume. On the one hand, this leads to unsightlyness and complaints due to the folds that then appear, but on the other hand, the cotton fleece no longer fulfills its intended purpose.

Auch die Verarbeitung von stärkeren Wattevliesen führte nicht zum Erfolg, da die innerhalb des Watte­vlieses angeordneten Schaumstoffkerne trotz ihrer möglichen Weichheit nicht den anschmiegsamen Effekt von Naturmaterialien aufweisen, sondern unter Be­lastung zu einer Verdichtung geführt werden, die je­den Polstereffekt ausschließen.Even the processing of thicker nonwovens did not lead to success, because the foam cores arranged inside the nonwoven fabric, despite their possible softness, do not have the supple effect of natural materials, but instead lead to a compression under load, which excludes any cushioning effect.

Aus der DE-A 20 19 488 ist ein Schaumstoffkörper be­kannt, der von mindestens zwei sich gegenseitig durchdringenden Schlitzsystemen durchsetzt ist, wo­bei jeder Schlitz des einen Systems mindestens von einem Schlitz eines anderen Systems geschnitten wird. Durch diese Maßnahme wird die Steifigkeit des Hartschaumes überwunden, und es entstehen an der Oberfläche Zäpfchen und im Inneren ein Netz von Stäbchen, die sich bei Belastung elastisch verbie­gen sollen und beim Entlasten zurückschnellen sol­len. Ein solcher Körper hat sich in der Praxis aber nicht bewährt, da einerseits das Herstellungsverfah­ren zu aufwendig ist und andererseits die sich kreu­zenden Schlitze die Festigkeit des Schaumstoffkerns so verringern, daß kein üblicher Polstereffekt mehr erreichbar ist.From DE-A 20 19 488 a foam body is known which is penetrated by at least two mutually penetrating slot systems, each slot of one system being cut by at least one slot of another system. This measure overcomes the stiffness of the rigid foam, and there are suppositories on the surface and a network of rods inside, which are supposed to bend elastically when loaded and snap back when relieved. Such a body has in practice not proven, because on the one hand the manufacturing process is too complex and on the other hand the intersecting slots reduce the strength of the foam core so that no usual cushioning effect can be achieved.

Der Erfindung liegt die Aufgabe zugrunde, ausgehend von den zum Stand der Technik gehörenden Polsterkör­pern, aus einem Schaumstoffkern einen Polsterkörper so zu gestalten, daß der Polsterkörper seine Pol­ster- und Ventilationseigenschaften auch bei starken Belastungen beibehält, trotzdem aber einen angeneh­men Polstereffekt ergibt.The invention is based on the object, starting from the cushion bodies belonging to the prior art, to design a cushion body from a foam core in such a way that the cushion body maintains its cushioning and ventilation properties even under heavy loads, but nevertheless results in a pleasant cushioning effect.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteran­sprüchen erläutert.Advantageous configurations are explained in the subclaims.

Durch den erfindungsgemäßen Polsterkörper wird durch das Stanzen einer Weichschaumstoffbahn die an sich typische Charakteristik einer solchen Schaumstoff­bahn so verändert, daß die Ware weich fällt und die gestanzte Bahn die Klimatisierung unterstützt. Durch das Einstanzen der Schnitte wird ferner bewirkt, daß der Benutzer in dem Schaumstoffkern einsitzt und nicht - wie dies bisher bei Schaumstoffbahnen der Fall ist - auf dieser aufsitzt.The cushion body according to the invention, by punching a soft foam sheet, changes the characteristic of such a foam sheet, which is typical per se, in such a way that the goods fall soft and the punched sheet supports the air conditioning. The punching of the cuts also causes the user to sit in the foam core and not - as was previously the case with foam webs - to sit thereon.

Durch die nur bereichsweise vorgesehene Verbindung der Abdeckung, beispielsweise aus einem Gewebe, Ge­wirke oder Vlies, werden zwischen der Abdeckung und dem gestanzten Schaumstoffkern - insbesondere bei Benutzen des Polsterkörpers - Lufträume geschaffen, die den so gebildeten Polsterkörper sympatischer und griffiger machen. Es wird neben dem sogenannten fäl­ligen Charakter eine bessere Polsterwirkung erzielt und durch die Dehnungsmöglichkeit der Abdeckung gegenüber dem Kern wird der bisher auftretende so­genannte "Segeltucheffekt" der Abdeckung vermieden.The connection of the cover, for example made of a woven, knitted or non-woven fabric, only in certain areas creates air spaces between the cover and the punched foam core, in particular when the cushion body is used. that make the upholstered body formed in this way more sympathetic and easy to grip. In addition to the so-called mature character, a better cushioning effect is achieved, and the so-called "canvas effect" of the cover, which has previously occurred, is avoided by the possibility of the cover stretching.

Anpassungen an unterschiedliche Einsatzzwecke können dadurch vorgenommen werden, daß unterschiedliche Materialien für die Abdeckung auf beiden Seiten des Schaumstoffkernes eingesetzt werden.Adaptations to different purposes can be made by using different materials for the cover on both sides of the foam core.

Durch den erfindungsgemäßen Vorschlag wird also ein Polsterkörper geschaffen, der in weitesten Bereichen einsetzbar ist, gute Klimatisierungseffekte auf­weist, ein weiches und anschmiegsames Verhalten be­sitzt und der in Kombination mit anderen Polstermit­teln beispielsweise auch als Fülltasche für stab- und/oder kugelförmige Polsterkörper ideale Polste­rungseffekte ergibt.The proposal according to the invention thus creates an upholstery body which can be used in the broadest areas, has good air-conditioning effects, has a soft and conformable behavior and which, in combination with other upholstery means, also provides ideal upholstery effects, for example as a filling pocket for rod-shaped and / or spherical upholstery bodies.

Der erfindungsgemäße Polsterkörper kann speziell für die Ummantelung von Polsterkissen-Kernen oder Ma­tratzenrohlingen eingesetzt werden, bei denen eine weich modellierende Oberfläche verlangt wird. Er be­steht vorzugsweise aus einem 20 mm starken Kern aus extrem weichem, hochwertigem Schaumstoff, der rap­portmäßig so mit Stanzschnitten versehen ist, daß die Oberflächenspannung des Schaumes total gebrochen werden kann. Die elastischen Eigenschaften des Schaumkernes verändern sich hierdurch in träge ela­stiche Eigenschaften und die bisherigen typischen Eigenschaften des Aufsitzens ändern sich in die des modellierenden Einsitzens. Ober- und Unterseite kön­nen mit einem Spinnvlies abgedeckt sein. Hierbei wird vorzugsweise die Oberseite mit einer besonders weichen Ausführung versehen. Durch die Anordnung der Abdeckung mit mehr oder weniger intermittierender Befestigung wird erreicht, daß selbst bei feinsten anschließenden Bezugsstoffen oder auch Leder, keine Konturen sichtbar werden, so daß sich also eine ab­solut glatte Kissenoberfläche erreichen läßt.The upholstery body according to the invention can be used especially for the sheathing of upholstered cushion cores or blank mattresses, in which a soft modeling surface is required. It preferably consists of a 20 mm thick core made of extremely soft, high-quality foam, which is provided with punched cuts in such a way that the surface tension of the foam can be totally broken. As a result, the elastic properties of the foam core change to sluggish elastic properties and the previous typical properties of sitting change to that of modeling sitting. The top and bottom can be covered with a spunbond. Here the top side is preferably provided with a particularly soft design. The arrangement of the cover with more or less intermittent fastening ensures that no contours are visible even with the finest upholstery fabrics or leather, so that an absolutely smooth cushion surface can be achieved.

Durch die erfindungsgemäße Anordnung wird ein ge­sundheitsförderndes Sitzen erreicht, und zwar durch eine körpergerechte Formgebung mit einem Höchstmaß an Druckentlastung.A health-promoting sitting is achieved by the arrangement according to the invention, namely by a shape that is appropriate for the body and with a maximum of pressure relief.

Ein Ausführungsbeispiel der Erfindung wird nachfol­gend anhand der Zeichnungen erläutert. Die Zeich­nungen zeigen dabei in

  • Fig. 1 einen Polsterkörper, bestehend aus einem Schaumstoffkern, einer Abdeckung und einer Umhüllung, in den
  • Fig. 2 bis 8 verschiedene Stanzmuster für den Polster­kern.
An embodiment of the invention is explained below with reference to the drawings. The drawings show in
  • Fig. 1 is a cushion body, consisting of a foam core, a cover and an envelope, in the
  • Fig. 2 to 8 different punching patterns for the upholstery core.

In Fig. 1 ist mit 1 ein Polsterkörper bezeichnet, der aus einer Umhüllung 2, einem Schaumstoffkern 3 und einer beiderseits des Schaumstoffkernes 3 an­geordneten Abdeckung 4 bzw. 5 besteht. Der Schaum­stoffkern 3 besteht aus einzelnen Schaumstoffbah­nen.In Fig. 1, 1 denotes a cushion body which consists of a covering 2, a foam core 3 and a cover 4 or 5 arranged on both sides of the foam core 3. The foam core 3 consists of individual foam sheets.

Jede Schaumstoffbahn 3 ist mit Stanzschnitten 6 aus­gerüstet, die in einem entsprechenden Muster - so wie in den Fig. 2 bis 8 dargestellt - angeordnet sein können.Each foam sheet 3 is equipped with die cuts 6, which can be arranged in a corresponding pattern - as shown in FIGS. 2 to 8.

Die Abdeckung 4 bzw. 5 ist bereichsweise mit dem Schaumstoffkern 3 im Randbereich durch Vernähen oder Versteppen oder aber im übrigen Bereich material­schlüssig, beispielsweise durch Verkleben, Ver­schweißen usw. verbunden, wobei beispielsweise punktförmige Verklebungsstellen in einem Raster vorgesehen sein können, das in seinem Rastermaß so gewählt wird, daß zwischen den einzelnen material­schlüssigen Verbindungspunkten genügende Freiräume und damit Bewegungsmöglichkeiten zwischen der Ab­deckung 4 und 5 und dem Schaumstoffkern 3 gegeben ist. Die Verbindung zwischen den Abdeckungen 4 und 5 und dem Schaumstoffkern 3 können punktförmig, lini­enförmig od. dgl. vorgesehen werden.The cover 4 or 5 is connected in some areas to the foam core 3 in the edge area by sewing or quilting or else in the rest of the area in a material-locking manner, for example by gluing, welding, etc., for example punctiform gluing points can be provided in a grid that has such a grid dimension is chosen that between the individual material connection points there is sufficient free space and thus movement possibilities between the cover 4 and 5 and the foam core 3. The connection between the covers 4 and 5 and the foam core 3 can be provided in a punctiform, linear or the like.

Die Abdeckungen 4 und 5 können aus einem Vlies, einem Gewebe, einer Gewirke- oder einer Folienbahn bestehen und können beiderseits des Schaumstoffker­nes 3 unterschiedlich ausgebildet sein.The covers 4 and 5 can consist of a fleece, a woven fabric, a knitted or a film web and can be designed differently on both sides of the foam core 3.

Die Stanzschnitte 6 können geradlinig, winkelförmig oder gebogen ausgebildet sein. Durch die Art der Stanzschnitte kann das elastische Verhalten des Schaumstoffkernes beeinflußt werden.The die cuts 6 can be straight, angular or curved. The elastic behavior of the foam core can be influenced by the type of die cuts.

Werden zwei Schaumstoffbahnen mit durchgehenden Stanzschnitten in Längs- und Querrichtung versehen, werden gleichzeitig sowohl die beiden Schaumstoff­bahnen innenflächig miteinander als auch die die Schaumstoffbahnen abdeckenden Materialien, z. B. Ge­webe, durch Klebepunkte oder wahlweise wellenförmige Strichverklebungen miteinander verbunden, also:

  • 1. Unterseite der oberen Abdeckung 4 mit Oberseite der ersten gestanzten Schaumstoffbahn 3.
  • 2. Unterseite dieser Schaumstoffbahn 3 mit Oberseite der zweiten gestanzten Schaumstoffbahn 3.
  • 3. Unterseite der zweiten gestanzten Schaumstoffbahn 3 mit Oberseite der unteren Abdeckung 5.
If two foam webs are provided with continuous punch cuts in the longitudinal and transverse directions, both the two foam webs are simultaneously on the inside with one another and the materials covering the foam webs, e.g. B. fabric, connected by glue dots or optionally wave-shaped line gluing, so:
  • 1. Bottom of the top cover 4 with the top of the first punched foam sheet 3.
  • 2. The underside of this foam sheet 3 with the top of the second stamped foam sheet 3.
  • 3. Underside of the second stamped foam sheet 3 with the top of the lower cover 5.

Der Verbundstoff enthält somit drei Klebeseiten.The composite therefore contains three adhesive sides.

Die Schaumstoffbahnen können in den Stärken variie­ren, wobei maximal etwa 80 mm angestrebt werden. Die Stärke der dicksten Bahn wird etwa 40 mm sein, die der dünnsten etwa 2 mm.The thickness of the foam sheets can vary, with a maximum of about 80 mm being aimed for. The thickness of the thickest web will be about 40 mm, that of the thinnest about 2 mm.

Die durchgehenden Stanzschnitte sind rapportmäßig in Längs- und Querrichtung eingebracht und so angeord­net, daß die verbleibenden Materialverbindungen eine höhere Anzahl von Waschprozessen durchstehen. Als Abdeckung kommen Gewebe, Gewirke, Vliese, Folien usw. in Betracht.The continuous die cuts are made in the longitudinal and transverse directions and arranged so that the remaining material connections withstand a higher number of washing processes. Woven fabrics, knitted fabrics, nonwovens, foils, etc. can be used as cover.

Mit dieser Verfahrensweise wird es ermöglicht, eine Palette von neuen Produkten herzustellen, insbeson­dere für Autositzabpolsterungen und Auflagen für die Krankenpflege zur Verhinderung des Decubitus. Der besondere Effekt liegt darin, daß die Materialkombi­nation in Sandwichbauweise konstruiert werden kann und die die Füllung abdeckenden Materialien nicht durch Versteppen - wobei immer eine Markierung der Steppnähte gegeben ist - sondern durch die geschil­derte Verbindungsweise bündig aufgebracht ist. Die nicht vollflächige Kaschierung bewirkt, daß kein "Segeltucheffekt" auftritt, der Federweg und somit die Polstereigenschaften der innenliegenden ge­stanzten Schaumstoffbahnen voll erhalten bleiben. Diese Polstereigenschaften, die jedoch vor dem Stanzschnitt eher eine sperrige Elastizität aufwei­sen, haben nach dem Stanzschnitt eine flexible, spannungslose und somit angepaßte und unterstützende Elastizität.This procedure makes it possible to manufacture a range of new products, especially for car seat upholstery and nursing pads to prevent pressure ulcers. The special effect lies in the fact that the material combination can be constructed in a sandwich construction and the materials covering the filling are not stitched by quilting - whereby there is always a marking of the stitching - but by the described connection method. The non-full-surface lamination means that no "canvas effect" occurs, the spring travel and thus the cushioning properties of the internal punched foam sheets are fully retained. These upholstery properties, however, before Die cuts tend to have a bulky elasticity, have a flexible, tension-free and thus adapted and supportive elasticity after the die cut.
