Abstract

The invention relates to a cushion part, in particular for a motor vehicle, comprising a foam element and a cover that covers the foam element, said cover being fastened to the foam element by means of a zipper, wherein a fabric strip of a zipper half is foamed into the foam element at the base of a basting groove provided in the foam element. The aim of the invention is to provide a zipper that enables a curved course of the basting point between the cover and the foam element and at the same time reliably prevents foam from reaching the teeth or closing elements when a half of the zipper is foamed in. Said aim is achieved in that flexible sealing elements (4-10) are integrated into the fabric strip (2) of the zipper half (1) and prevent foam from entering the basting groove (14) when the fabric strip (2) of the zipper half (1) is foamed in.

Description

Polsterteil, insbesondere für Kraftfahrzeugsitze Die vorliegende Erfindung betrifft Polsterteil, insbesondere für Kraftfahrzeugsitze gemäß dem Oberbegriff des Anspruchs 1.  Upholstered part, in particular for motor vehicle seats The present invention relates to a cushion part, in particular for motor vehicle seats according to the preamble of claim 1.

Derartige Polsterteile sind beispielsweise in der DE 10 2005 013 613 A1 und der FR 2 911 821 A1 offenbart. Bei derartigen Polsterteilen besteht das Problem, dass beim Einschäumen des Stoffstreifens einer Reißverschlusshälfte Schaum an die Zähne des Reißverschlusses gelangen kann, derart, dass seine Funktion zumindest beeinträchtigt ist. Such upholstery parts are disclosed, for example, in DE 10 2005 013 613 A1 and FR 2 911 821 A1. In the case of such upholstered parts, there is the problem that, when the fabric strip of a zipper half laps in, foam can reach the teeth of the zipper in such a way that its function is at least impaired.

Aus der WO 2008/050393 A1 ist ein Polsterteil bekannt, bei dem eine Hälfte eines Gleitverschlusses am Grunde einer im Schaumkörper vorgesehenen Abheftnut in den Schaumkörper eingeschäumt ist. Diese Gleitverschlusshälfte ist als Kunststoffformteil, welches z. B. als Spritzgussteil hergestellt ist, ausgeführt. An einen in den Schaumkörper einzuschäumenden Steg der Gleitverschlusshälfte sind einstückig Querstege angeformt, die in der Ausschäumform den Zugang von Schaum zu dem Schließkörper der Gleitverschlusshälfte verhindern. Die als Kunststoffformteile ausgeführten Hälften des Gleitverschlusses sind ohnehin schon biegesteif und werden durch die angespritzten Stege zur Verhinderung des Schaumzutritts zu den Schließkörpern noch weiter versteift. Diese bekannten Gleitverschlusshälften sind daher nicht für einen oftmals gewünschten oder erforderlichen bogigen Verlauf der Abheftstellen zwischen Bezug und Schaumkörper geeignet. From WO 2008/050393 A1, a cushion part is known, in which one half of a sliding closure is foamed into the foam body at the base of a release groove provided in the foam body. This Gleitverschlusshälfte is as a plastic molding, which z. B. is made as an injection molded part executed. To be foamed into the foam body web of Gleitverschlusshälfte integrally transverse webs are formed, which prevent the foam in the foam access to the closing body of Gleitverschlusshälfte. The designed as plastic mold halves of the slide fastener are already rigid and are further stiffened by the molded webs to prevent the foam access to the closing bodies. These known Gleitverschlusshälften are therefore not suitable for a often desired or required curved course of the Abheftstellen between reference and foam body.

Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen, und einen Reißverschluss zur Verfügung zu stellen, der einen bogigen Verlauf der Abheftstelle zwischen Bezug und Schaumkörper ermöglicht und gleich- Object of the present invention is to remedy this situation, and to provide a zipper that allows a boggy course of the Abheftstelle between cover and foam body and equal

BESTÄTIGUNGSKOPIE zeitig zuverlässig den Schaumzutritt beim Einschäumen einer Hälfte des Reißverschlusses zu den Zähnen bzw Schließmitteln verhindert. CONFIRMATION COPY reliably prevents foam entry on foaming of one half of the zipper to the teeth or closing means.

Diese Aufgabe wird erfindungsgemäß durch ein Polsterteil gelöst, wel- ches die Merkmale des Anspruchs 1 aufweist. This object is achieved according to the invention by a padding part which has the features of claim 1.

Erfindungsgemäß sind also in den flexiblen Stoffstreifen der einzuschäumenden Reißverschlusshälfte flexible Dichtmittel integriert, die zum Einen die Funktionssicherheit des Reißverschlusses sicherstellen, indem sie den Zutritt von Schaum zu den Reißverschlusszähnen bzw. -spiralen beim Einschäumen der Reißverschlusshälfte verhindern und zum Anderen ein kurviges, z. B. gebogenes Einschäumen der Reißverschlusshälfte ermöglichen, da sie aufgrund ihrer Flexibilität die einzuschäumende flexible Reißverschlusshälfte nicht versteifen. According to the invention flexible sealing means are thus integrated into the flexible fabric strip of the zipper half to be foamed, which on the one hand ensure the functional reliability of the zipper by preventing the access of foam to the zipper teeth or spirals during foaming of the zipper half and on the other a curvy, z. B. allow flexible foaming of the zipper half, since they do not stiffen the flexible zipper half to be foamed because of their flexibility.

Schaumkörper mit eingeschäumter Reißverschlusshälfte. Die in den Fig. 1-8 dargestellten Reißverschlusshälften 1 bestehen wie üblich aus einem Stoffstreifen 2, an dessen einem Ende in den dargestellten Ausführungsbeispielen eine Spirale 3 eingewebt ist. Anstelle der Spiralen 3 können natürlich auch z. B. Zähne aus Kunststoff an den Stoffstreifen 2 angespritzt sein. Anstelle eines Reißverschlusses kann auch ein entsprechend ausgeführter Gleitverschluss zur Anwendung kommen. Foam body with foamed zipper half. The zipper halves 1 shown in FIGS. 1-8 consist, as usual, of a fabric strip 2, at the one end of which a spiral 3 is woven in the exemplary embodiments shown. Instead of the spirals 3 can of course also z. B. teeth made of plastic molded onto the fabric strip 2. Instead of a zipper, a correspondingly executed slide closure can also be used.

Die in den Fig. 1-8 dargestellten Reißverschlusshälften 1 unterscheiden sich von den bisher Üblichen dadurch, dass sie integrierte Dichtmittel aufweisen, die den Zutritt von Schaum beim Einschäumen der Reißverschlusshälfte 1 zu den Spiralen 3 verhindern. The zipper halves 1 shown in FIGS. 1-8 differ from the conventional ones in that they have integrated sealing means which prevent the access of foam during foaming of the zipper half 1 to the spirals 3.

Im Ausführungsbeispiel gemäß Fig. 1 ist das flexible Dichtmittel eine Schnur 4, die an den Stoffstreifen 2 angeklebt ist. In the embodiment according to FIG. 1, the flexible sealing means is a cord 4, which is glued to the fabric strip 2.

Bei den Ausführungsbeispielen gemäß den Fig. 2 und 3 ist das flexible Dichtmittel eine in den Stoffstreifen 2 einseitig oder beidseitig eingewebte Raupe 5. In the exemplary embodiments according to FIGS. 2 and 3, the flexible sealing means is a bead 5 woven into the cloth strip 2 on one side or on both sides.

Bei dem Ausführungsbeispiel gemäß Fig. 4 ist an dem der Spirale 3 gegenüberliegenden Ende des Stoffstreifens 2 ein weiterer Stoffstreifen 6 durch eine Naht 7 befestigt. Dieser Stoffstreifen 6 kann, wie in Fig. 4 dargestellt ist, etwa rechtwinklig zu dem Stoffstreifen 2 abgeklappt werden. In the embodiment according to FIG. 4, at the end of the fabric strip 2 opposite the spiral 3, a further fabric strip 6 is fastened by a seam 7. As shown in FIG. 4, this fabric strip 6 can be folded down approximately at right angles to the fabric strip 2.

Bei den Ausführungsbeispielen gemäß den Fig. 5 und 6 ist weiterer Stoffstreifen 8 bzw. 9 in den Stoffstreifen 2 eingewebt, wobei die Stoffstreifen 8 bzw. 9 den Stoffstreifen 2 T-förmig kreuzen. In Fig. 5 ist der eingewebte Streifen 8 eben, während er in Fig. 6 eine gewölbte Form besitzt. ln den Fig. 7 und 8 sind weitere Ausführungsbeispiele dargestellt, bei denen die flexiblen Dichtmittel aus dem Stoffstreifen 2 selbst gebildet sind, indem seine der Spirale 3 gegenüberliegenden Enden zu einer Schlaufe 10 geformt sind, deren freies Ende entweder durch eine Naht 11 (Fig. 7) oder ein Klebestelle 12 am Stoffstreifen 2 festgelegt ist. In the embodiments according to FIGS. 5 and 6, further fabric strips 8 and 9 are woven into the fabric strip 2, wherein the fabric strips 8 and 9, respectively, cross the fabric strip 2 in a T-shape. In Fig. 5, the woven strip 8 is flat, while in Fig. 6 has a curved shape. 7 and 8 further embodiments are shown, in which the flexible sealing means are formed from the fabric strip 2 itself by its opposite ends of the spiral 3 are formed into a loop 10, the free end either by a seam 11 (Fig. 7) or a splice 12 is fixed to the fabric strip 2.

In Fig. 9 ist der Boden einer Form 11 zur Herstellung eines Schaumkörpers 12 für ein Polsterteil, z. B. ein Sitzkissenteil eines Kraftfahrzeugsitzes, dargestellt. Die Form 11 ist bereits mit Schaum, z. B Polyurethanschaum, ausgeschäumt. In dem in Fig. 9 dargestellten Detail ist eine Leiste 13 der Form 11 zu sehen, die eine Abheftnut 14 im fertigen Schaumkörper 12 vorgibt, wie aus Fig. 10 ersichtlich ist. In Fig. 9, the bottom of a mold 11 for producing a foam body 12 for a cushion part, for. B. a seat cushion part of a motor vehicle seat, shown. The mold 11 is already foam, z. B polyurethane foam, foamed. In the detail shown in Fig. 9, a strip 13 of the mold 11 can be seen, which defines a Abheftnut 14 in the finished foam body 12, as shown in FIG. 10 can be seen.

In den Schaumkörper 12 ist etwa eine Hälfte des Stoffstreifens 2 einer Reißverschlusshälfte 1 eingeschäumt. Um einen sicheren Halt der Reißverschlusshälfte 1 im Schaumkörper 12 zu erreichen, kann der Stoffstreifen 2 grobmaschig ausgeführt sein, so dass der Schaum die Maschen durchdringen kann. Da die Spirale 3 in der Abheftnut 14 frei zugänglich sein muss, ist in dem Steg 13 der Form 11 eine Aussparung 1 vorgesehen, die beim Ausschäumvorgang der Form 11 schaumfrei bleiben muss. Dafür sorgen in dem in den Fig. 9 und 10 dargestellten Ausführungsbeispiel die beiden in den Stoffstreifen 2 eingewebten Raupen 5, die die Aussparung 15 gegenüber dem Innenraum der Form 11 abdichten. Anstelle der Reißverschlusshälfte gemäß Fig. 3 können auch die anderen in den Fig. 1 , 2 und 4-8 dargestellten Reißverschlusshälften 1 eingeschäumt werden, wobei dann die flexiblenIn the foam body 12 is about one half of the fabric strip 2 of a zipper half 1 foamed. In order to achieve a secure hold of the zipper half 1 in the foam body 12, the fabric strip 2 can be made coarsely meshed, so that the foam can penetrate the mesh. Since the spiral 3 must be freely accessible in the filing groove 14, a recess 1 is provided in the web 13 of the mold 11, which must remain foam-free during the foaming of the mold 11. For this purpose, in the exemplary embodiment illustrated in FIGS. 9 and 10, the two beads 5, which are woven into the fabric strip 2, seal off the recess 15 from the interior of the mold 11. Instead of the zipper half according to FIG. 3, the other zipper halves 1 shown in FIGS. 1, 2 and 4-8 can also be foamed in, in which case the flexible

Dichtmittel 4, 6, 8, 9 und 10 für eine Abdichtung der Aussparung 15 gegenüber dem Innenraum der Form 11 sorgen. Sealant 4, 6, 8, 9 and 10 provide for a seal of the recess 15 relative to the interior of the mold 11.

Der Schaumkörper 2 ist durch zwei Bezugteile 16 und 7 (Fig. 0) ka- schiert. Deren freien Enden sind durch eine Naht 8 mit einer weiteren Reißverschlusshälfte 19 verbunden. Zum Abheften der Bezugteile 16 und 17 am Schaumkörper 12 werden die beiden Reißverschlusshälften 1 und 19 durch Betätigung eines nicht dargestellten Reißverschlussschiebers miteinander verbunden. The foam body 2 is cased by two reference parts 16 and 7 (FIG. Their free ends are connected by a seam 8 with another zipper half 19. For filing the reference parts 16 and 17 am Foam body 12, the two zipper halves 1 and 19 are connected together by operation of a zipper slider, not shown.
