Verfahren zur Herstellung eines PolstermaterialsMethod for producing a cushioning material

Die Erfindung betrifft die Herstellung eines Polstermaterials, insbesondere für Armaturenbretter und Seiteninnenteile an Kraftfahrzeugen. The invention relates to the production of a cushioning material, in particular for dashboards and inner side parts on motor vehicles.

Eine einfache Herstellung von Polstermaterial auf der Basis von Schaumstoffen aus Äthylen oder teilvernetztem Polyäthylen durch EF-Verschweißung war bisher nicht möglich, da sich solche Schaumstoffe nicht KF-verschweißen lassen. Es bestand aber ein Bedürfnis nach einem solchen Material, da Polyäthylens cha urnstoffe besonders wünschenswerte physikalische Eigenschaften haben. A simple production of upholstery material on the basis of foams made of ethylene or partially cross-linked polyethylene EF welding was previously not possible because such Do not allow CF to weld foams. But there was Such a material is needed because polyethylene cha urnstoffe have particularly desirable physical properties.

Seiteninnenteile aus Kraftfahrzeugen besteht, v/elches dadurch gekennzeichnet ist, daß man Schäumstoffbahnen aus gegebenenfalls teilvernetztem Polyäthylen an Unterlagen in der Weise mustormäSig ilF-anschweißt, daß man über und unter der Schaumstoffbahn flexible thermoplastischeThe present invention closes this gap by providing a method for producing an upholstery material, in particular for dashboards and.

Auf der über der Schaumstoffbahn liegenden thermoplastischen Kunststoffbahn kann eine Dekorfolie, angebracht werden oder die betreffende Bahn ist selbst als Dekorfolie ausgebildet.A decorative film, or the The web in question is itself designed as a decorative film.

Zweckmäßig werden Schaumstoffbahnen aus gegebenenfalls teilvernetztem Polyäthylen mit einem Raum-Gewicht von 30 bis 200 kg/nr bei einer Dicke von 2 bis 15 mm verwendet. Die Dicke der Folien liegt zwischen 0,1 und 2 mm. Bei Geweben und Gewirken handelt es sich um ein Material mit einer Fadenstärke, wie sie allgemein in der Textilindustrie üblich ist bei möglichst engem Kontakt der einzelnen Fäden. Es versteht sich von selbst, daß je dicker die dielektrisch erwärmbaren Materialien sind, um so besser durchführbar und haltbarer sind die erzielten Verbindungen.Foam webs made from optionally partially crosslinked material are expedient Polyethylene with a volume weight of 30 to 200 kg / nr with a thickness of 2 to 15 mm is used. The thickness of the foils is between 0.1 and 2 mm. When it comes to woven and knitted fabrics, it is a material with a thread thickness as it is generally used In the textile industry, it is common practice for the individual threads to come into contact as closely as possible. It goes without saying that the thicker it is The dielectrically heatable materials are, the more feasible and durable the connections are.
