Abstract

The foam item is especially a seat, and has a cover (2) which is tensioned over the seat surface. The cover is tensioned in an indentation (3) in the seat, against retaining elements (4) which are set into the foam body (1). The elements are roughly parallel to the indentation, and have a profile in a direction which is transverse to their longitudinal extension, with at least one wedgelike surface which points towards the indentation. The elements may be in the form of mouldings which are made from a synthetic material, or from a moulded textile fabric which is impregnated with a thermoplastic binder.

Description

Die vorliegende Erfindung betrifft einen Schaumstoffartikel mit Bezug, ins­ besondere einen Schaumstoffsitz, insbesondere auf Basis Polyurethanschaumstoff.The present invention relates to a foam article with reference special a foam seat, especially based on polyurethane foam.

Obwohl es bereits eine Reihe von Vorschlägen gibt, Schaumstoffartikel mit Bezug dadurch herzustellen, daß der Bezug in eine Schäumform eingelegt wird und der Schaumstoffkörper an dem Bezug angeschäumt wird (siehe z. B. EP-A 386 890), hat sich diese Technik noch nicht durchgesetzt.Although there are a number of proposals, foam related items to make by placing the cover in a foam mold and the Foam body is foamed on the cover (see e.g. EP-A 386 890), this technology has not yet become established.

Üblicherweise werden Schaumstoffsitze noch so hergestellt, daß zunächst ein Schaumstoffkörper durch Verschäumen einer Polyurethan-Reaktivmischung in einer Schaumform hergestellt werden und der Schaumstoffkörper anschließend mit einem Bezug bespannt wird. Als Verankerungselemente zur Bespannung mit dem Bezug werden dabei Stahldrahteinleger in die Form eingelegt, bevor diese aus­ geschäumt wird. Der Bezug kann dann mittels Klammerelementen, Haken oder durch Vernähen gegen den Einleger gespannt werden. Die auftretenden Spann­ kräfte werden durch den Einleger auf den Schaumstoff übertragen. Aufgrund der geringen Kontaktfläche zwischen Stahldraht und Schaumstoffkörper treten insbe­ sondere bei wechselnder Belastung des Schaumstoffsitzes lokale Spannungskräfte zwischen Stahldrahteinleger und Schaumstoff auf, die die Reißdehnung des Schaumstoffs überschreiten können. Im Laufe des Gebrauchs eines solchen Schaumstoffsitzes läßt daher die Verspannung des Bezuges nach.Foam seats are usually still manufactured so that a first Foam body by foaming a reactive polyurethane mixture in be produced in a foam mold and then the foam body with a cover is covered. As anchoring elements for covering with the Steel wire inserts are inserted into the mold before they are removed is foamed. The cover can then by means of clip elements, hooks or can be tightened against the insert by sewing. The occurring tension Forces are transferred to the foam through the insert. Due to the small contact area between steel wire and foam body occur in particular Local tension forces, especially with changing loads on the foam seat between steel wire insert and foam, which the elongation at break of the Foam can exceed. In the course of using such Foam seat therefore reduces the tension of the cover.

Erfindungsgemäß wird nun vorgeschlagen, Verankerungselemente einzusetzen, die eine Querausdehnung in Bezug auf die auftretenden Spannkräfte aufweisen. Insbesondere sollen die Verankerungselemente keilförmig gegen die Spannkräfte ausgebildet sein.According to the invention, it is now proposed to use anchoring elements that have a transverse expansion in relation to the clamping forces that occur. In particular, the anchoring elements should be wedge-shaped against the clamping forces be trained.

Gegenstand der vorliegenden Erfindung ist demgemäß ein Schaumstoffartikel, ins­ besondere Schaumstoffsitz, mit Bezug, wobei der Bezug in einer in dem Schaum­ stoffkörper verlaufenden Kerbe gegen unterhalb der Kerbe im Schaumstoffkörper eingelassene Halterungselemente über die Sitzfläche gespannt ist, mit dem Kenn­ zeichen, daß die im wesentlichen parallel zur Kerbe des Schaumstoffkörper aus­ gedehnten Halterungselemente quer zu ihrer Längsausdehnung ein Profil min­ destens einer keilförmig gegen die Kerbe weisenden Fläche ausgebildet.The present invention accordingly relates to a foam article, ins special foam seat, with cover, the cover in one in the foam  notch running underneath the notch in the foam body recessed bracket elements is stretched over the seat, with the identifier Signs that are essentially parallel to the notch of the foam body stretched bracket elements transverse to their longitudinal extent a profile min least a wedge-shaped surface facing the notch.

Nach einer Ausführungsform der vorliegenden Erfindung sind die Verankerungs­ elemente in Form von extrudierten Kunststoffprofilen ausgebildet. Dabei können als Kunststoffe solche Kunststoffe eingesetzt werden, die mit dem Polyurethan­ schaum einen festen Verbund bilden. Geeignet sind z. B. PVC-, ABS-, und ins­ besondere bevorzugt PUR-Kunststoffe.According to one embodiment of the present invention, the anchors are elements in the form of extruded plastic profiles. You can as plastics such plastics are used, which with the polyurethane foam form a firm bond. Are suitable for. B. PVC, ABS, and ins particularly preferred PUR plastics.

Nach einer weiteren Ausführungsform der vorliegenden Erfindung besteht das Ver­ ankerungselement aus einem mit einem thermoplastischen Bindemittel verstärkten grobmaschigem Textilgewebe, insbesondere Jutegewebe, das unter Wärmezufuhr in die gewünschte Kontur geprägt ist.According to a further embodiment of the present invention, the Ver Anchor element made of a reinforced with a thermoplastic binder coarse-mesh textile fabric, especially jute fabric, which is heated is shaped into the desired contour.
