Figur 1 zeigt anhand eines Querschnitts den Aufbau einer Rückenlehne oder eines Sitzteils 22, wobei der Polsterschaum 1 an der von dem Sitzenden abgewandeten Seite (die nachfolgend als B-Seite bezeichnet wird) von einem Vlies 2 begrenzt wird. Auf der dem Sitzenden zugewandten Seite (die nachfolgend als A-Seite bezeichnet wird) ist der Schaum von einem Bezug 3 umfasst. Zur aktiven Belüftung ist ein Radiallüfter 4 vorgesehen, der schwingungsgedämpft im Schaum selbst angeordnet ist und zwar auf der B-Seite. Die Sitzfläche oder die Lehne weisen des Weiteren eine Luftverteilereinrichtung 5 auf, die hier eine Luftverteilerstruktur 6 und quer dazu angeordnete Luftführungskanäle 7 aufweist. Die Luftverteilungsstruktur 6 besteht aus direkt in den Schaum eingebrachte Luftgräben 8 oder Luftkanälen, die sich entlang der B-Seite erstrecken und nicht aus einer Abstandsgewirkeschicht. Luft wird somit von dem Radiallüfter 4 in den Schaum gesogen, anschließend über das Sitzpolster oder Lehnenpolster durch die Luftgräben 8 der Luftverteilungsstruktur 6 verteilt und dann über die Luftführungskanäle 7 auf die A-Seite des Sitzteils transportiert (vergleiche Pfeilverlauf). FIG. 1 shows on the basis of a cross section of the structure of a backrest or a seat part 22, wherein the padding foam 1 on the side facing away from the sitting side (hereinafter referred to as B-side) is bounded by a nonwoven 2. On the seated side (hereinafter referred to as A side), the foam is covered by a cover 3. For active ventilation, a radial fan 4 is provided, which is arranged vibration-damped in the foam itself and that on the B side. The seat surface or the backrest furthermore have an air distribution device 5, which here has an air distributor structure 6 and air ducts 7 arranged transversely thereto. The air distribution structure 6 consists of directly introduced into the foam air trenches 8 or Air channels that extend along the B side and not from a spacer fabric layer. Air is thus sucked by the radial fan 4 in the foam, then distributed over the seat cushion or backrest cushion by the air trenches 8 of the air distribution structure 6 and then transported via the air ducts 7 on the A side of the seat part (see arrow).

Der erfindungsgemäß vorgeschlagene Sitz kann vom Grundsatz her ohne Abstandsgewirke und somit ohne eine separate luftdurchlässige Schicht ausgestattet sein. Die luftführenden Kanäle 7 und Gräben 8 werden in das Schaumpolster integriert.The inventively proposed seat can be equipped in principle without spacer knitted fabric and thus without a separate air-permeable layer. The air-conducting channels 7 and trenches 8 are integrated into the foam cushion.

Es ist aber auch möglich, Abstandsgewirke zu verwenden. Diese können dann sowohl auf der A- als auch auf der B-Seite der Lehne oder des Sitzteils 22 angeordnet sein. Figur 2 zeigt die Anordnung eines Abstandsgewirkes 9 oder auch die von Gummihaar zwischen dem Schaum 1 und dem Bezug 3 auf der A-Seite. Alternativ oder zusätzlich kann das Abstandsgewirke 9 oder Gummihaar auf der B-Seite angeordnet sein und zwar innerhalb der Luftgräben 8 der Luftverteilungsstruktur 6 (Figur 3).But it is also possible to use spacer knitted fabric. These can then be arranged both on the A- and on the B-side of the backrest or the seat part 22. FIG. 2 shows the arrangement of a spacer fabric 9 or the rubber hair between the foam 1 and the cover 3 on the A-side. Alternatively or additionally, the spacer fabric 9 or rubber hair can be arranged on the B side, namely within the air trenches 8 of the air distribution structure 6 (FIG. FIG. 3 ).

Damit die Luftgräben 8 auf der B-Seite bei einer Belastung durch den Sitzenden nicht zusammengedrückt und in ihrer Wirkungsweise behindert werden, wird der Polsterschaum aus einem 2-Zonenschaum 10 gebildet (vergleiche Figur 4). Die A-Seite wird mit einem weicheren Schaum ausgebildet, während die B-Seite aus einem härteren Schaum geformt wird, der somit die Luftgräben 8 stabilisiert. Die Zonengrenze 11 zwischen dem unteren härteren Schaum und dem oberen weicheren Schaum verläuft oberhalb der Luftgräben 8. Auf diese Weise wird auch der Radiallüfter 4 stabilisiert und gegen Belastung geschützt.So that the air trenches 8 are not compressed on the B side under load from the seated person and impeded in their mode of operation, the upholstery foam is formed from a 2-zone foam 10 (cf. FIG. 4 ). The A side is formed with a softer foam, while the B side is formed of a harder foam, thus stabilizing the air trenches 8. The zone boundary 11 between the lower harder foam and the upper softer foam extends above the air trenches 8. In this way, the radial fan 4 is stabilized and protected against stress.

Figur 5 zeigt darüber hinaus, dass eine solche Stabilisierung beziehungsweise Fixierung des Radiallüfters 4 auch durch einen separate Schaumzone oder Schaumschicht 12 erreicht wird, die in der Nähe des Lüfters auf den Polsterschaum aufgebracht, vorzugsweise geklebt, wird. Dieser separate Schaum hält folglich den Lüfter. FIG. 5 shows, moreover, that such a stabilization or fixation of the radial fan 4 is also achieved by a separate foam zone or foam layer 12, which is applied, preferably glued, in the vicinity of the fan on the padding foam. This separate foam thus holds the fan.

Eine Luftverteilungsstruktur mit Luftgräben kann neben der B-Seite auch in der A-Seite des Polsterschaums eingebracht sein (Figur 6). Es sind dann neben den Luftführungskanälen 7 auf der A-Seite daran anschließende Luftgräben 13 in den Schaum 1 eingebracht, beispielsweise durch Fräsen. Die Luft kann dann auf größere Verteilungsbereiche auf der A-Seite abgegeben werden.An air distribution structure with air trenches can also be introduced in the A side of the upholstery foam in addition to the B side ( FIG. 6 ). There are next to the air ducts 7 on the A-side adjoining air trenches 13 introduced into the foam 1, for example by milling. The air can then be delivered to larger distribution areas on the A side.

Derartige größere Luftaustrittsbereiche auf der A-Seite oder Luftgräben 13 auf der A-Seite können auch durch separate Schnittschaumauflagen 14 gebildet werden. Diese werden mit entsprechenden Einschnitten beziehungsweise Aussparungen 15 der späteren Luftgräben 13 beziehungsweise Verteilerstrukturen vorbereitet und zwischen dem Schaum und dem Bezug auf der A-Seite angeordnet (Figur 7).
Werden diese Luftgräben 13 auf der A-Seite so ausgebildet, dass sie mit zwei Luftführungskanälen 7 in Wirkverbindung stehen, kann auch eine Luftführungseinrichtung 5 mit Hinterspülung erreicht werden. Luft fließt aus dem Lüfter durch einen Luftgraben 8 auf der B-Seite, durch einen ersten Luftführungskanal 7, dann durch einen Luftgraben 13 auf der A-Seite und zurück durch einen zweiten Luftführungskanal 7, der direkt an der B-Seite endet (Figur 8).Such larger air outlet areas on the A-side or air trenches 13 on the A-side can also be formed by separate cut foam pads 14. These are prepared with corresponding cuts or recesses 15 of the later air trenches 13 or distributor structures and arranged between the foam and the reference on the A side ( FIG. 7 ).
If these air trenches 13 are formed on the A-side so that they are in operative connection with two air ducts 7, an air-guiding device 5 with back-flushing can also be achieved. Air flows out of the fan through an air trench 8 on the B side, through a first air duct 7, then through an air trench 13 on the A side and back through a second air duct 7 which ends directly on the B side ( FIG. 8 ).

Die Figuren 9 und 10 zeigen weitere Möglichkeiten, die Luftgräben 8 zu stabilisieren.The Figures 9 and 10 show further possibilities to stabilize the air trenches 8.

Nach der Variante gemäß Figur 9 wird die Innenseite der Luftgräben 8 mit einem Flockenverbundschaum 16 ausgeformt, der als härteres Material stabilisiert.
Eine andere Ausführungsform zeigt die Figur 10, wobei hier die Innenseite des Luftgrabens 8 mit Hilfe eines aufsprühbaren härteren Material gegen Belastung gefestigt wird. Dieser Kleber 17 kann eine Gummihaut sein.According to the variant according to FIG. 9 the inside of the air trenches 8 is formed with a flock composite foam 16 which stabilizes as a harder material.
Another embodiment shows the FIG. 10 Here, the inside of the air trench 8 is strengthened by means of a sprayable harder material against stress. This adhesive 17 may be a rubber skin.

Die Figuren 16 und 17 zeigen schließlich noch weitere Möglichkeiten, die Luftgräben 8 und/oder 13 zu stabilisieren. Durch Stabilisierung der Form der Luftgräben 8 und/oder 13 durch Optimierung der Lastverteilung beziehungsweise der Kraftverteilung auf den Luftgraben 8 und/oder 13 wird eine spezielle Formgebungen 26, 27 der Luftgräben 8 und/oder 13 erzielt. Nach Figur 16 werden in einer ersten speziellen Formgebung 26 schräge Wandungen ausgeführt, die mit einem bogenförmigen Abschluss in Richtung des Sitzenden (A-Seite) ausgebildet sind.
Nach Figur 17 werden in einer zweiten speziellen Formgebung 27 parabelförmige Wandungen ausgeführt, wobei der geschlossene Bereich der Parabel wiederum in Richtung des Sitzenden (A-Seite) ausgeführt ist.The FIGS. 16 and 17 Finally, show other ways to stabilize the air trenches 8 and / or 13. By stabilizing the shape of the air trenches 8 and / or 13 by optimizing the load distribution or the force distribution on the air trench 8 and / or 13, a special shapes 26, 27 of the air trenches 8 and / or 13 is achieved. To FIG. 16 be carried out in a first specific shaping 26 inclined walls, which are formed with an arcuate conclusion in the direction of the seated end (A-side).
To FIG. 17 27 parabolic walls are executed in a second special shaping, wherein the closed area of the parabola is again designed in the direction of the seated end (A-side).

Eine Belastung der Luftgräben 8 und/oder 13 führt bei dieser Formgebung 26, 27 zu einer geringeren Veränderung des Querschnittes des Luftgräben 8 und/oder 13, so dass die gewünschten, vorausgelegten Strömungsverhältnisse im Wesentlichen beibehalten werden.
Ferner reduziert sich in beiden Fällen die Gefahr des Durchdrückens beziehungsweise Durchsitzens im Bereich der Luftgräben 8 und/oder 13, da diese eine höhere Stabilität aufweisen.
Es kann vorteilhaft sein, über die Luftverteilungsstruktur 6 eine Sogwirkung zu erzeugen, wie dies mit Hilfe der Figur 11 gezeigt ist. Diese Struktur ist insgesamt kreisförmig ausgebildet und erlaubt eine zirkulierende Strömung. Luft wird von dem auf einer Seite angeordneten Lüfter 4 in die Verteilerstruktur eingeblasen und wird wieder zum Einblaspunkt zurückgeführt, wobei dann die Sogwirkung entsteht. Entlang der Ring-Verteilerstruktur sind die dazu im Wesentlichen quer verlaufenden Luftführungskanäle 7 zur A-Seite angeordnet, um die Luft zur A-Seite zu transportieren.
Figur 12 stellt ein weiteres Muster einer Luftverteilerstruktur 6 - hier in einem Lehnenschaum - dar. Es·sind zwei Radiallüfter 4 und zwei Luftverteilungsstrukturen 6 pro Lehne 20 angeordnet. Die Luft fließt auf der linken Seite über einen wesentlichen Hauptverteilerarm 18 und zwei Seitenarme 19 entlang der B-Seite der Lehne 20 und über diese in die quer angeordneten Luftführungskanäle 7. Auf der rechten Seite ist ein Muster mit im Wesentlichen zwei Verteilerarmen 21 dargestellt.A load on the air trenches 8 and / or 13 results in this shaping 26, 27 to a smaller change in the cross section of the air trenches 8 and / or 13, so that the desired, predefined flow conditions are maintained substantially.
Furthermore, in both cases, the danger of pushing through or slipping through in the area of the air trenches 8 and / or 13 is reduced, since these have a higher stability.
It may be advantageous to generate a suction effect via the air distribution structure 6, as with the aid of FIG. 11 is shown. This structure has an overall circular shape and allows a circulating flow. Air is blown by the arranged on one side fan 4 in the manifold structure and is returned to the Einblaspunkt again, in which case the suction effect arises. Along the ring distributor structure, the air ducts 7, which extend essentially transversely to it, are arranged to the A-side in order to transport the air to the A-side.
FIG. 12 represents a further pattern of an air distributor structure 6 - here in a backrest foam. There are two radial fans 4 and two air distribution structures 6 per backrest 20 are arranged. The air flows on the left side via a main Hauptverteilerarm 18 and two side arms 19 along the B side of the backrest 20 and via this in the transverse air ducts 7. On the right side, a pattern with two main distribution arms 21 is shown.

Mit Hilfe der vorgeschlagenen Luftverteilerstruktur 6 beziehungsweise der Luftgräben 8 auf der B-Seite eines Schaumpolsters ist es möglich, beliebige Verteilungsmuster zu gestalten, die auch den Behaglichkeitsanforderungen des Sitzenden an den einzelnen Körperstellen entgegenkommt. So kann es zum Beispiel sinnvoll sein, die Nierenpartien weniger stark oder andere Körperpartien punktuell stärker zu kühlen. Ein derartiges Muster ist mit der Figur 13 dargestellt. In die B-Seite eines Sitzkissens oder Sitzteils 22 sind in das Schaummaterial sternförmig auseinander laufende Luftgräben 8 eingebracht. Diese werden von einem Radiallüfter 4 versorgt, der an einem Endpunkt eines Luftgrabens 8 angeordnet ist. Zwei Luftgräben 8 können in die Beinbereiche herausgezogen sein.
Wie eben beschrieben, werden zum Transport der Luft Luftführungskanäle 7 genutzt, die sich von der B- zur A-Seite erstrecken. Für diesen Transport können auch die Abheftgräben 23 verwendet werden, die erfindungsgemäss zur Arretierung des Bezuges beziehungsweise der Bezugsfahne 24 imWith the help of the proposed air distribution structure 6 and the air trenches 8 on the B side of a foam cushion, it is possible to design any distribution pattern that also accommodates the comfort requirements of the sitter at the individual body sites. For example, it may make sense to cool the kidney parts less strongly or other parts of the body more selectively. Such a pattern is with the FIG. 13 shown. In the B-side of a seat cushion or seat part 22 star-shaped diverging air trenches 8 are introduced into the foam material. These are supplied by a radial fan 4, which is arranged at an end point of an air trench 8. Two air trenches 8 can be pulled out into the leg areas.
As just described, are used to transport the air air ducts 7, which extend from the B to the A side. For this transport and the filing trenches 23 may be used according to the invention for locking the cover or the reference lug 24 in

Schaumpolster vorliegen. Eine solche Ausführungsform ist mit Hilfe der Figur 14 dargestellt. In Weiterbildung dieser Ausführungsform können die Bezugsfahnen 25 selbst gelocht beziehungsweise perforiert sein und sich somit auch quer durch einen Luftgraben 8 an der B-Seite erstrecken. Dies hat den Vorteil, dass sich unterhalb eines Abheftgrabens 23 ein Luftgraben 8 ausdehnen kann, was die Variabilität der Muster bei den Luftverteilungsstrukturen erhöht.Foam cushion available. Such an embodiment is with the help of FIG. 14 shown. In a further development of this embodiment, the reference lugs 25 may be perforated or perforated themselves and thus also extend transversely through an air trench 8 at the B side. This has the advantage that an air trench 8 can extend below a filing trench 23, which increases the variability of the patterns in the air distribution structures.

Schließlich ist von der Erfindung noch ein saugender Radial-Lüfter 4 umfasst, der am Schaum befestigt ist oder im Schaum angeordnet ist. Auf diese Weise entsteht mit Hilfe der in das Polster eingebrachten Luftverteilungsstruktur 6 und den Luftführungskanälen 7 ein Kühleffekt beim Sitzenden beziehungsweise auch ein Feuchtigkeitsabtransport (nicht gezeigt).
Die Figuren 18 bis 25 zeigen eine einfache Montage und alternative zusätzliche Befestigungslösungen des Lüfters 4 im Schaum, insbesondere in der separat für den Lüfter 4 vorgesehenen Schaumzone 12, in der nach der bisherigen Beschreibung der Lüfter 4 gemäß der zur Figur 5 beschriebenen möglichen Ausführung eingebettet und fixiert ist. Anhand der Schnittdarstellung (untere Darstellung) und einer Unteransicht (obere Darstellung) der Figur 18 wird zunächst die Montagelösung "Knopflochlösung" einer ersten Ausführungsform erläutert.
Gemäß der unteren Darstellung muss der Lüfter 4 in den Hohlraum 31 des Schaumes, insbesondere der separat vorgesehenen Fixierungsschicht, die insbesondere als Schaumzone 12 ausgebildet ist, eingebracht werden.
Die Unterseite (B-Seite) einer Sitzfläche oder Lehne ist dabei jedoch während des Herstellungsprozesses bereits mit dem Vlies 2 versehen. Zu Montagezwecken erhält das Vlies 2 gemäß der ersten Ausführungsform (Figur 18) Einschnitte 28 in der Art eines Knopflochs - "Knopflochlösung" -, die ausgehend von einer Montageöffnung 30, dem "Knopfloch", orthogonal zur Montageachse des Lüfters 4 verlaufen.
Die Länge der Einschnitte 28 richtet sich nach der Flexibilität des eingesetzten Vlieses 2.
Nach erfolgter Montage überdeckt das Vlies 2 den Lüfter 4 in Überschneidungen 35, so dass sich hieraus zusätzlicher Halt für den Lüfter 4 ergibt.Finally, the invention includes a sucking radial fan 4, which is attached to the foam or disposed in the foam. In this way, with the help of the introduced into the cushion air distribution structure 6 and the air ducts 7, a cooling effect at the seated or a moisture removal (not shown).
The FIGS. 18 to 25 show a simple installation and alternative additional mounting solutions of the fan 4 in the foam, especially in the separately provided for the fan 4 foam zone 12, in the previous description of the fan 4 according to the FIG. 5 embedded possible embodiment described and is fixed. Based on the sectional view (bottom view) and a bottom view (top view) of FIG. 18 First, the mounting solution "buttonhole solution" of a first embodiment will be explained.
According to the lower illustration, the fan 4 must be introduced into the cavity 31 of the foam, in particular the separately provided fixing layer, which is designed in particular as a foam zone 12.
However, the underside (B side) of a seat or backrest is already provided with the fleece 2 during the production process. For assembly purposes, the nonwoven 2 according to the first embodiment obtains (FIG. FIG. 18 ) Button-hole type cutouts 28, "buttonhole solution", which are orthogonal to the mounting axis of the fan 4 from a mounting hole 30, the "buttonhole".
The length of the incisions 28 depends on the flexibility of the fleece 2 used.
After installation, the fleece 2 covers the fan 4 in overlaps 35, so that this results in additional support for the fan 4.

Vorzugsweise ist der Hohlraum 31 in der Schaumzone 12 bereits entsprechend der Kontur des Lüfters 4 hergestellt worden, so dass der Lüfter 4 bei der Montage tatsächlich nur noch durch das Vlies 2 "eingefädelt" beziehungsweise "eingeknöpft" werden muss.Preferably, the cavity 31 in the foam zone 12 has already been produced according to the contour of the fan 4, so that the fan 4 actually only needs to be "threaded" or "buttoned" during assembly by the fleece 2.

Die Figur 19 zeigt analog zur oberen Darstellung der Figur 18 eine ähnliche Lösung in einer zweiten Ausführungsform, wobei statt entsprechender Einschnitte 28 Aussparungen 32 ausgeführt sind. Diese zweite, ebenfalls in einer Unteransicht dargestellte zweite Ausführungsform bietet sich bei weniger flexiblen Vliesmaterialen an. Es ergeben sich wie dargestellt andere Überschneidungsbereiche 35.The FIG. 19 shows analogous to the upper representation of FIG. 18 a similar solution in a second embodiment, wherein instead of corresponding cuts 28 recesses 32 are executed. This second, also shown in a bottom view second embodiment lends itself to less flexible nonwoven materials. As shown, other overlap areas 35 result.

Ferner zeigen die Figuren 20 und 21 jeweils in einer Unteransicht jeweils eine dritte und vierte Ausführungsform, bei der auf Einschnitte 28 beziehungsweise Aussparungen 32 im Vlies 2 verzichtet wird und die Überschneidungsbereiche 35 zwischen Vlies 2 und Lüfter 4 dadurch entstehen, dass das "Knopfloch" 30 also die Montageöffnung durch das Vlies 2 nun nicht mehr rund, sondern gemäß Figur 20 oval beziehungsweise gemäß Figur 21 etwas abweichend von einer runden Form ausgebildet wird.Furthermore, the show FIGS. 20 and 21 in each case in a bottom view in each case a third and fourth embodiment in which incisions 28 or recesses 32 in the fleece 2 is dispensed with and the overlapping areas 35 between fleece 2 and fan 4 arise because the "buttonhole" 30 thus the mounting opening through the fleece. 2 not round anymore, but according to FIG. 20 oval or according to FIG. 21 is formed slightly different from a round shape.

Durch diese Lösung ergeben sich die in Figur 20 beziehungsweise 21 dargestellten Überschneidungen 35, wodurch ein Lüfter 4 zusätzlich zu den beschriebenen Maßnahmen durch das Vlies 2 in dem Hohlraum 31 gehalten wird beziehungsweise dessen Montage besonders leicht durchführbar ist.This solution results in the FIG. 20 or 21 shown overlaps 35, whereby a fan 4 is held in addition to the measures described by the web 2 in the cavity 31 and its installation is particularly easy to carry out.

Um eine weitere Fixierung des Lüfters 4 im Schaum 1 beziehungsweise gemäß der beschriebenen Ausführungsformen in einer Schaumzone 12 - einer separaten Fixierungsschicht - zu gewährleisten, zeigen die Figuren 22 und 23 eine erste Befestigungslösung mit federnden Halteelementen 36, die in Figur 22 in einer Draufsicht auf einen Lüfter und in Figur 23 in einer Seitenansicht auf den Lüfter dargestellt sind.In order to ensure a further fixation of the fan 4 in the foam 1 or according to the described embodiments in a foam zone 12 - a separate fixing layer - show the FIGS. 22 and 23 a first fastening solution with resilient retaining elements 36, which in FIG. 22 in a plan view of a fan and in FIG. 23 are shown in a side view on the fan.

Nach der beschriebenen Montage des Lüfters 4 und "Einfädeln" beziehungsweise "Einknöpfen" des Lüfters 4 in den dafür vorgesehenen Hohlraum 31 erreicht das federnde Haltelement in einer Art Widerhaken eine Fixierung des Lüfters 4. Vorraussetzung ist, selbstverständlich, dass die Schaumzone 12 von ihren Abmessungen und ihrer Kontur her an den Lüfter 4 bereits im Vorfeld angepasst worden ist, so dass die federnden Haltelemente 36 während der Montage entsprechend an den Lüfter 4 herangedrückt werden und sich, sobald der Lüfter 4 seine gewünschte Position eingenommen hat, federnd an der Schaumzone 12 abstützen.After the described assembly of the fan 4 and "threading" or "buttoning" of the fan 4 in the space provided 31, the resilient holding element in a kind of barbs a fixation of the fan reaches 4. Prerequisite is, of course, that the foam zone 12 of their dimensions and its contour to the fan 4 has already been adjusted in advance, so that the resilient holding elements 36 are pressed down accordingly during assembly to the fan 4 and, as soon as the fan 4 has assumed its desired position, resiliently supported on the foam zone 12 ,

Ähnlich verhält es sich mit einer zweiten Befestigungslösung gemäß Figur 24 und gemäß Figur 25, die wiederum eine Draufsicht auf einen Lüfter 4 beziehungsweise einen Schnitt durch einen Lüfter 4 darstellt. Hierbei handelt es sich nicht um federnde Halteelemente 36, sondern um starre Halteelemente 37, die sich tatsächlich widerhakenartig in der Schaumzone 12, die in den Figuren 22 - 25 nicht dargestellt ist, verhaken, wobei gemäß Figur 25 klar ist, dass auch mehrere Halteelemente 37 angeordnet werden können. Die mögliche mehrfache Anordnung gilt selbstverständlich auch für die federnden Halteelemente 36 nach den Figuren 22, 23.The situation is similar with a second fastening solution according to FIG. 24 and according to FIG. 25 , which in turn represents a plan view of a fan 4 or a section through a fan 4. These are not resilient retaining elements 36, but to rigid support members 37, which are actually barb-like in the foam zone 12, in the Figures 22-25 is not shown, hook, according to FIG. 25 It is clear that a plurality of holding elements 37 can be arranged. The possible multiple arrangement of course applies to the resilient support members 36 after the FIGS. 22, 23 ,
