Abstract

The invention relates to a seat cushion (1) for chairs, benches or the like, in particular of sports facilities, consisting of an elastic heat-insulating layer (3, 4) which is completely enclosed by a flexible cover (2). In order to provide a seat cushion which is inexpensive to manufacture and, even when moist, retains its full function, that is to say can be used, the cover is formed from a fibrous plastic film consisting of olefin threads sprayed onto a surface and shaped under pressure and temperature. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Sitzkissen für Stühle, Bänke oder dgl., insbesondere von Sportstätten, bestehend aus einer elastischen, wärmeisolierenden Schicht, die vollständig von einer flexiblen Hülle umschlossen ist.The invention relates to a seat cushion for chairs, benches or the like., In particular of sports facilities, consisting of an elastic, heat-insulating layer which is completely enclosed by a flexible cover.

Stühle oder Bänke in Sportstätten bestehen aus einem weitgehend witterungsbeständigen Material. Dies führt dazu, daß sie hart und, in Abhängigkeit von der Jahreszeit, kalt sind und keiner­lei Sitzkomfort bieten. Besucher derartiger Sportstätten brin­gen sich daher häufig Sitzkissen mit, die vielfach auch im Be­reich der Sportstätten angeboten und verkauft werden. Derartige Sitzkissen bestehen aus einer elastischen, wärmeisolierenden Schicht, beispielsweise aus Schaumgummi, die vollständig von einer flexiblen Hülle aus einem textilen Gewebe umschlossen ist. Aufgrund dieser Ausbildung der flexiblen Hülle und der elastischen, wärmeisolierenden Schicht wirkt dasselbe bei regnerischem Wetter wie ein Schwamm und ist dann unbrauchbar. Trotz einfachster Gestaltung ist ein derartiges Sitzkissen verhältnismäßig teuer. Dabei ist auch zu berücksichtigen, daß derartige Sitzkissen, beispielsweise in Abhängigkeit vom Ver­lauf der Sportveranstaltung, aus Freude oder Verärgerung weg­geworfen werden.Chairs or benches in sports facilities are made of a largely weather-resistant material. This leads to the fact that they are hard and, depending on the season, cold and offer no seating comfort. Visitors to such sports facilities therefore often bring seat cushions with them, which are often offered and sold in the area of sports facilities. Such seat cushions consist of an elastic, heat-insulating layer, for example of foam rubber, which is completely enclosed by a flexible cover made of a textile fabric. Due to this design of the flexible cover and the elastic, heat-insulating layer, the same acts as a sponge in rainy weather and is then unusable. Despite the simplest design, such a seat cushion is relatively expensive. It should also be borne in mind that such seat cushions are thrown away out of joy or annoyance, for example depending on the course of the sporting event.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Sitzkissen für Stühle, Bänke oder dgl., insbesondere von Sportstätten, zu schaffen, welches preiswert herstellbar ist und auch bei Feuchtigkeit seine volle Funktion beibehält, also benutzt wer­den kann. Zusätzlich soll noch die Wärmeisolierung des Sitz­kissens verbessert werden.The invention is based on the object of creating a seat cushion for chairs, benches or the like, in particular of sports facilities, which is inexpensive to manufacture and maintains its full function even in moisture, that is to say can be used. In addition, the heat insulation of the seat cushion is to be improved.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung bei einem Sitzkissen der eingangs beschriebenen Gattung vorgeschlagen, daß die Hülle aus einer faserigen, aus auf eine Fläche aufge­spritzten und unter Druck und Temperatur verformten Olefin­fäden bestehenden Kunststoffolie gebildet ist. Eine derartige Folie ist preiswert herzustellen und wasserundurchlässig, so daß also die elastische, wärmeisolierende Schicht ihre volle Funktion beibehält. Die Hülle kann dabei umschlagartig ausge­bildet sein, in die die elastische, wärmeisolierende Schicht, ähnlich wie bei einem Briefumschlag, eingeschoben wird. Durch einen Haft- oder Klebestreifen ist diese Hülle dann verschließ­bar. Die elastische, wärmeisolierende Schicht kann aus min­destens einer Luftpolsterfolie gebildet sein. Dies hat den Vor­teil, daß sich eine solche Schicht nicht mit Wasser vollsaugen kann. In vorteilhafter Weise kann die Luftpolsterfolie auf der Innenfläche der faserigen Kunststoffolie kaschiert sein. Dies vereinfacht die Herstellung eines derartigen Sitzkissens.To achieve this object, it is proposed according to the invention in a seat cushion of the type described at the outset that the cover is formed from a fibrous plastic film consisting of olefin threads sprayed onto a surface and deformed under pressure and temperature. Such a film is inexpensive to manufacture and water-impermeable, so that the elastic, heat-insulating layer maintains its full function. The envelope can be designed like an envelope, into which the elastic, heat-insulating layer is inserted, similar to an envelope. This envelope can then be closed by an adhesive or adhesive strip. The elastic, heat-insulating layer can be formed from at least one bubble wrap. This has the advantage that such a layer cannot absorb water. The bubble wrap can advantageously be laminated on the inner surface of the fibrous plastic film. This simplifies the manufacture of such a seat cushion.

Die Erfindung wird nachfolgend anhand eines in einer Zeichnung ausschnittsweise dargestellten Ausführungsbeispieles näher er­läutert.The invention is explained in more detail below with reference to an exemplary embodiment shown in a drawing.

In dieser Zeichnung ist ein Sitzkissen 1 im Schnitt darge­stellt, welches aus einer Hülle 2 aus einer faserigen Kunst­stoffolie besteht. Bei der Herstellung einer solchen Kunst­ stoffolie werden zunächst sehr dünne Olefinfasern über Düsen gesponnen und unregelmäßig auf eine Unterlage gespritzt. An­schließend wird aus diesen aufgespritzten Kunststoffasern lediglich unter Anwendung von Druck und Temperatur, also ohne Klebstoff oder dgl., eine Folie mit faseriger Struktur geformt. Aus dieser Kunststoffolie wird dann ein Zuschnitt für die Hülle 2 hergestellt, der ähnlich eines Briefumschlages oder einer Versandtasche ausgebildet sein kann. In einer besonderen Vorrichtung werden dann die Zuschnitte gefalzt und geklebt und damit die Hüllen 2 gebildet. In die einseitig offene Hülle 2 werden dann zwei Schichten 3,4 aus einer an sich bekannten, nicht dargestellten Luftpolsterfolie eingeschoben. Sobald sich diese Schichten 3,4 in der Hülle 2 befinden, wird dieselbe über einen Haft- oder Klebestreifen geschlossen.In this drawing, a seat cushion 1 is shown in section, which consists of a cover 2 made of a fibrous plastic film. When making such art very thin olefin fibers are first spun over nozzles and sprayed irregularly onto a base. Subsequently, a film with a fibrous structure is formed from these sprayed-on plastic fibers using only pressure and temperature, that is to say without adhesive or the like. From this plastic film, a blank for the sleeve 2 is then produced, which can be designed similar to an envelope or a mailing bag. The blanks are then folded and glued in a special device, thus forming the sleeves 2. Two layers 3, 4 of an air cushion film, which is known per se and not shown, are then inserted into the envelope 2, which is open on one side. As soon as these layers 3, 4 are in the casing 2, the latter is closed with an adhesive or adhesive strip.

In Abänderung des erläuterten Ausführungsbeispieles ist es mög­lich, die aus einer Luftpolsterfolie bestehende Schicht 3,4 mit der Innenfläche der Hülle 2 bzw. der Kunststoffolie durch Kaschierung zu verbinden. Der Arbeitsvorgang für das Einschieben bzw. Einstecken der Schichten 3,4 in die Hülle 2 entfällt dann.In a modification of the exemplary embodiment explained, it is possible to connect the layer 3, 4 consisting of an air cushion film to the inner surface of the casing 2 or the plastic film by lamination. The process for inserting or inserting the layers 3, 4 into the casing 2 is then omitted.
