Abstract

The invention relates to cushion cores which are produced from fibre materials which are, or become by post-treatment, preferably fire-retardant and self-extinguishing. The cushion cores can be produced with or without moulded-in cores or structures in moulds, in any suitable geometric dimensions. The fibres which are preferably plastics fibres are extruded primarily directly or indirectly into the moulding tool or secondarily laid in and, if necessary, subjected to a chemical and/or physical post-treatment. The cushion cores removed from the moulding tools retain to a large extent their shape assumed there, the hardened fibres act resiliently in them.

Description

Polsterkerne und Verfahren zur HersteLLungUpholstery cores and manufacturing process

den Polstenkenne.the upholstery know.

Die Enfindung bezteht sich auf Poistenkenne der vorgenonnten Ant. die dus Materialien gefertigt werder welche vorwtegend feuerhemmend und selbsterloeschend sind.The invention is based on the knowledge of the poets of the aforementioned Ant. the dus materials are manufactured which are primarily fire-retardant and self-extinguishing are.

Die bekanten Polsterschdeume und anderen Polstermatertalten stnd ueberwtegend Leicht entzuendbar und entwtckeln bet thner Verbrennung Rouch- und gifilge Gase. Um die Entflammbarkeit der Polsterkerne zu verhindern, ist bekannt, dIese mit feuerfesten Bezuegen zu umhuellen. Die vollstbondtge Umhuellung mit feuenfesten Bezuegen ist in vtelen Foellen technolsch schwiepig oder unmoeglich (z.B. bei durchtnetenden Tellen wie Stuetzrohre usw.). sodass unter Hstzeeinwinkung sich verfluesstgender Polsterkernschaum abtropfen und am Boden ausbrennen kann. Deshalb koennen auch z .B. in der Luftfuhrt bisher verwendete feuerfeste Gewebe bezugs stoffe tn vieLen Faellen alletn keinen ausretchenden Polstenkernschutz bteten.The well-known upholstery foam and other upholstery matertales are overwhelming Easily flammable and, when burnt, evolve rouch and gifilge gases. In order to prevent the upholstery core from becoming flammable, it is known to use fireproof Regarding to envelop. The fully bonded wrapping with fire-proof covers is Technologically unstable or impossible in vtelen skins (e.g. in the case of soothing Places such as support tubes etc.). so that under the angle of the wind, it becomes more dissolute The upholstery core foam can drip off and burn out on the floor. Therefore z .B. The fireproof fabric upholstery fabrics used up to now in the air consists of a great number of materials Falls do not require protruding padding core protection.

Weiterhin tst dt e Verwendung von Flammschutzmitteln bekannt, die auf dte Polsterkernschaeume aufgebracht oder bet der Herstellung der Polster in den Schaum eingearbeitet werden. Diese HiLfsmitteL haben u.a.Furthermore, the use of flame retardants is known Applied to the upholstery core foam or used in the manufacture of the upholstery in the foam can be incorporated. These tools have i.a.

folgende Nachtelte : Ste stnd empftndltch gegen LichteinstrahLung, betm Gebrauch treten diese Flammschutzmittel aus den Schaeumen aus, sodass nur ein zeitlich und temperaturbegrenzter Schutz gegeben ist.the following night tents: Stand sensitive to light, When in use, these flame retardants escape from the foam, so that only one Temporary and temperature-limited protection is given.

Demgemdess Liegt der Enftndung die Aufgabe zugrunde.Accordingly, the development is based on the task.

etnen Polsterkern derart anzugeben, dass dteser dte feuerfesten bzw. feuerhemmenden Etgenschaften selbst in stch traegt, sodass auf zusoetzliche feuerfeste Bezuege verztchtet werden kann; oder bet Verwendung von zusdetzltchen feuerfesten Bezuegen die Stcherhelt der Feuerbestdendlgkett tnsgesamt erhoeht wtrd.specify a cushion core in such a way that it is fireproof or fire-retardant properties even in stch, so that additional fire-proof Remuneration can be forbidden; or use additional refractory bags With regard to the sting of the fire resistance chain, the total is increased.

Dtese Aufgabe wtnd durch dte kennzetchnenden Merkmate des Anspruches 1 geloest. Weitere Ausgestaltungen der Erfindung sind in den Unteranspsruechen angegeben. Die Erfindung ist anhand eines Beispiets in den Zetchnung dargestellt und In der Beschretbung naeher erlaeutert.This task is based on the characteristic features of the claim 1 solved. Further embodiments of the invention are given in the subclaims. The invention is illustrated by way of example in the drawings and in Description explained in more detail.

Fig. 1 ein Polstenkern (2) hir betspielbaft in der Aufsuchrung etnes Polsterkerns in einem Kopfpolster (6) Der Polsterkern (2), der aus feuerfesten oder -hemmenden vorzugsweIse Kunststoffasern (1) besteht, beinhaltet einen zusaetzltchen Kern (5) in Form etnes Rohres,wobet der Polsterkenn mit einer feuerfesten Gewebelage (3) umhuellt ist und zusdetzlich einen deussenen Bezugstoff aufweist. Derantige Kombinationen koennen Anwendung finden bet der Herstellung von Polstern in der Fahrzeug-, Luftfahrt- und Moebeltndustrie.Fig. 1 an upholstery core (2) hir betspielbaft in the search etnes Cushion core in a head cushion (6) The cushion core (2), which is made of fireproof or -inhibiting preferably white synthetic fibers (1), contains an additional bag Core (5) in the form of a tube, the upholstery identification with a fireproof fabric layer (3) is wrapped and also has a German cover fabric. Derantige Combinations can be used in the manufacture of upholstery in the vehicle, Aviation and furniture industries.

Der Polsterkern wird in etner Form hergestellt wobei die Kontur derselben der aeusseren Gestalt des gewuenschten Polsterkerns entspeicht. Die vonzugsweise feuerfesten oder feuerhemmenden Kunststoffasern (1) werden mit HiLfe von entsprechenden Vorrichtungen und Maschinen in die vorgeferttgte Form gebrocht, vertetlen stch und erstarren In der gewuenschten Lage. Anschliessend werden die Polsterkerne der Form entnommen Eine wettere Ausgestaltung ist es, mit Hilfe Form Maschinen und Antagen Polsterkernmatertal in Form von Platten oder Rohtetlen herzustellen, die einer weiteren Verwendung oder Nacharbeit zugefuehnt wer den koemmen.The upholstery core is made in a single shape, the contour of which is the same corresponds to the outer shape of the desired upholstery core. The partial Fireproof or fire-retardant synthetic fibers (1) are made with the help of appropriate Devices and Machines broken into the prefabricated form, Vertetlen stch and freeze in the desired position. Then the Upholstery cores taken from the form A more effective design is with the help of form Machines and components to manufacture upholstery core material in the form of panels or raw materials, that can be used or reworked.

Das Verfahren zur Herstellung der Polsterkenne orn prlmaer mit dem direkten oder Indtrekten Extrnubieren der Faser In Formen durchgefuehrt wenden, o oder sekundaer mit Etnbringen von Fasern In Formen, wobe diese einer chemischen und/oder physikolischen Nochbehandlung und/oder Zusorzbehandlung unterzogen werder Koennen ; die Zusatzbehandlung enfolgt vorzugsweise in der Form selbst.The process for making the upholstery orn prlmaer with the direct or indirect extrusion of the fiber into molds carried out, o or secondarily with the application of fibers in forms, this being a chemical and / or physical treatment and / or additional treatment Can ; the additional treatment is preferably carried out in the form itself.

Die Fasern wtrken aufgrund Ihrer mechanische Etgenschaften und des gewaehtten Faserproftis federnd und einzeLn und in der Gesamthet+ als polsterelement.The fibers work due to their mechanical properties and the Blown fiber professionals resiliently and individually and as a padding element in the whole.
