Abstract

An upholstered body made of foamed material, in particular for an upholstered component, such as head rest or the like, present on a motor vehicle seat. A head rest (1) which is attached to a motor vehicle seat has an upholstery carrier (2) onto which an internal part (3) is injection moulded. In turn an upholstery support (4) which faces the user of the seat is attached to the said internal part (3), the said upholstery support (4) and the internal part (3) being surrounded by a covering (5). The internal part (3) of the head rest (1) is produced from polyproplyene or polyethylene particle foam whilst the upholstered support (4) consists of polyurethane. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Polsterkörper aus Schaumstoff der im Oberbegriff des Patentanspruchs 1 ge­ nannten und aus der DE-OS 23 15 771 (Fig. 3) hervorge­ henden Art.The invention relates to a cushion body Foam of the ge in the preamble of claim 1 called and from DE-OS 23 15 771 (Fig. 3) emerge Art.

Aus dieser Druckschrift ist es bekannt, die Lehne eines Kraftfahrzeugsitzes aus einem zweischichtigen Schaumstoff zu fertigen, wobei die Unterschicht der Lehne aus einem tragenden, halbstarren Polyurethanschaum besteht, auf den ein weicher, das Polster bildender Schaum aufgebracht ist. Ein Polyurethanschaum hat jedoch nicht nur ein ver­ gleichsweise hohes Gewicht, sondern ist auch sehr schlecht recyclebar.From this publication it is known to have the backrest one Motor vehicle seat made of a two-layer foam to manufacture, the lower layer of the backrest from a load-bearing, semi-rigid polyurethane foam on which a soft foam that forms the cushion is applied is. However, a polyurethane foam has not only one ver equally high weight, but is also very difficult to recycle.

Aufgabe der Erfindung ist es daher, einen Polsterkörper der im Oberbegriff des Patentanspruchs 1 genannten Art derart auszubilden, daß der Kern des Polsterkörpers rela­ tiv leicht ist, während die Polsterauflage einen optima­ len Polsterwert aufweist. The object of the invention is therefore a cushion body the type mentioned in the preamble of claim 1 form such that the core of the cushion body rela tiv is light, while the cushion cover an optima len has a cushion value.  

Zur Lösung der Aufgabe sind die im kennzeichnenden Teil des Patentanspruchs 1 dargelegten Merkmale vorgesehen.To solve the problem are those in the characterizing part of claim 1 features provided.

Da der innenliegende Teil des Polsterkörper aus Polypro­ pylen oder Polyetylen-Partikelschaum gefertigt ist, hat er vorteilhafterweise ein geringes Gewicht, ist preisgün­ stig und umweltschonend zu fertigen und vor allem voll recyclebar.Since the inner part of the upholstery made of Polypro pylene or polyethylene particle foam is made it advantageously has a low weight and is inexpensive stig and environmentally friendly to manufacture and above all full recyclable.

Dabei kann die aus Polyurethan bestehende Polsterauflage auf den inneren Teil des Polsterkörpers aufgeschäumt, aufgeklebt oder auch durch Klammern oder dergleichen be­ festigt werden. Zweckmäßigerweise wird die aufgeklebte oder durch Klammern befestigte Polsterauflage aus Platten als ein sogenannter Schnittschaum ausgestanzt (Merkmale des Patentanspruchs 3).The padding made of polyurethane can be used foamed on the inner part of the cushion body, glued or be by brackets or the like be consolidated. Appropriately, the glued or upholstered pad made of panels attached by clips punched out as a so-called cut foam (characteristics of claim 3).

Ein aus Polypropylen oder Polyetylen-Partikelschaum be­ stehender, innenliegender Teil eines Polsterkörpers mit einer Formteildichte von etwa 25 g/l wird nach dem Schäumvorgang bei höherer Temperatur - nämlich bei etwa 100°C - ca. 24 Stunden getempert. Hierdurch wird vor­ teilhafterweise erreicht, daß die jeweilige, beim Schäum­ vorgang erlangte Form des innenliegendes Teils des Pol­ sterkörpers stets erhalten bleibt, d. h. insbesondere bei einem Klimawechsel nicht schrumpft oder sich in ähnlicher Weise verformt (Merkmale der Patentansprüche 2 und 4).One made of polypropylene or polyetylene particle foam standing, internal part of a cushion body with a molded part density of about 25 g / l is after Foaming process at a higher temperature - namely around 100 ° C - annealed for approx. 24 hours. Doing so will partially achieved that the respective, when foaming the shape of the internal part of the pole body is always preserved, d. H. especially at a climate change does not shrink or become similar Deformed way (features of claims 2 and 4).

Ein Ausführungsbeispiel der Erfindung ist in der Zeich­ nung dargestellt und wird im folgenden erläutert. Diese zeigt eine an einem Kraftfahrzeugsitz vorgesehene Kopf­ stütze in einem Vertikalschnitt.An embodiment of the invention is in the drawing shown and will be explained in the following. This shows a head provided on a motor vehicle seat support in a vertical section.

Die in der Zeichnung dargestellte, als ein Polsterkörper dienende Kopfstütze 1 ist über Tragstangen 7 an der Rückenlehne eines nicht dargestellten Fahrzeugsitzes an­ gebracht. Dabei weist die Kopfstütze 1 einen aus Kunst­ stoff bestehenden Polsterträger 2 auf, auf den ein innen­ liegender Teil 3 der Kopfstütze 1 aufgeschäumt ist. Der innenliegende Teil 3 besteht aus Polypropylen oder Poly­ etylen-Partikelschaum mit einer Formteildichte von etwa 25 g/l. Schließlich ist auf dem innenliegenden Teil 3 der Kopfstütze 1 frontseitig, also dem Sitzbenutzer zuge­ wandt, eine aus Polyurethan bestehende Polsterauflage 4 angebracht. Diese kann auf den innenliegenden Teil 3 auf­ geschäumt, aufgeklebt, durch Klammern oder in ähnlicher Weise befestigt werden.The headrest 1 shown in the drawing, serving as an upholstered body, is attached to support rods 7 on the backrest of a vehicle seat, not shown. The headrest 1 has an upholstery support 2 made of plastic, on which an inner part 3 of the headrest 1 is foamed. The inner part 3 consists of polypropylene or polyethylene foam with a molded part density of about 25 g / l. Finally, on the inner part 3 of the headrest 1 from the front, that is to say to the seat user, a pad 4 made of polyurethane is attached. This can be foamed onto the inner part 3 , glued, fastened by clips or in a similar manner.

Wie in der Zeichnung ersichtlich, ist sowohl der innen­ liegende Teil 3 als auch die Polsterauflage 4 von einem aus Textilmaterial, Leder, Kunststoff oder dergleichen bestehenden Bezug 5 umgeben, dessen übereinander liegende Ränder an der Unterseite des Polsterträgers 2 festgelegt sind.As can be seen in the drawing, both the inner part 3 and the cushion cover 4 are surrounded by a cover 5 made of textile material, leather, plastic or the like, the superimposed edges of which are fixed on the underside of the cushion carrier 2 .

Der innenliegende, aus Polypropylen oder Polyetylen-Par­ tikelschaum bestehende Teil 3 der Kopfstütze 1 wird nach dem Schäumvorgang bei höherer Temperatur, nämlich bei etwa 100°C, ca. 24 Stunden getempert. Durch dieses Ver­ fahren wird erreicht, daß die beim Schäumen erlangte Form des innenliegenden Teils 3 der Kopfstütze 1 stets, also auch bei einem Klimawechsel oder dergleichen Einflüsse, unverändert bleibt.The inner, made of polypropylene or polyetylene particle foam part 3 of the headrest 1 is annealed after the foaming process at a higher temperature, namely at about 100 ° C, for about 24 hours. By driving this United is achieved that the shape of the inner part 3 of the headrest 1 obtained during foaming always remains unchanged, that is, even with a change in climate or the like.
