Description

Die Erfindung betrifft eine Decke, insbesondere Bettdecke gemäß Anspruch 1.The invention relates to a blanket, in particular a duvet according to claim 1.

Eine Decke, insbesondere Bettdecke, mit einer aus zwei Deckblättern bestehenden Hülle, einer Füllung und einem zwischen den beiden Deckblättern angeordneten Zwischenblatt, ist z.B. aus dem DE-U-7.715.468 bekannt. Dort wird eine Decke gezeigt und beschrieben, bei der das Zwischenblatt mittig zwischen den beiden Deckblättern angeordnet ist und den Füllraum in zwei Teile aufteilt, die unterschiedlich gefüllt sind. Die eine Hälfte der Füllung kann aus natürlichen Daunen oder Federn bestehen, während die andere Hälfte der Füllung aus einem unverfestigten Faservlies, künstlichen Daunen od.dgl. bestehen kann.A blanket, in particular a bedspread, with a cover consisting of two cover sheets, a filling and an intermediate sheet arranged between the two cover sheets is e.g. known from DE-U-7.715.468. There a blanket is shown and described, in which the intermediate sheet is arranged centrally between the two cover sheets and divides the filling space into two parts, which are filled differently. Half of the filling can consist of natural down or feathers, while the other half of the filling can consist of an unconsolidated nonwoven fabric, artificial down or the like. can exist.

Das aus dieser DE-U-7.715.468 bekannte Zwischenblatt dient lediglich dazu, die beiden unterschiedlichen Füllungshälften voneinander zu trennen. Wegen der verwendeten Daunen muß das in der Regel aus einem gewebten Stoff bestehende Zwischenblatt "daunendicht" sein, damit die Daunen nicht durch das Zwischenblatt hindurchwandern.The intermediate sheet known from this DE-U-7.715.468 only serves to separate the two different filling halves from one another. Because of the down used, the intermediate sheet, which is usually made of a woven fabric, must be "down-proof" so that the down does not migrate through the intermediate sheet.

Bei dieser bekannten Decke sind die beiden Deckblätter durch das Zwischenblatt hindurch mittels einer Steppung miteinander verbunden.In this known blanket, the two cover sheets are connected to one another through the intermediate sheet by means of a quilting.

In verschiedenen, nicht vorveröffentlichten, auf den Anmelder zurückgehenden Patentanmeldungen wird nun auch schon eine Decke, insbesondere Bettdecke, vorgeschlagen, in der als Füllung kugelförmige Faseraggregate aus sphärisch miteinander verwickelten Fasern verwendet werden. Diese Faseraggregate gestatten es, eine solche Decke sehr leicht auszubilden.In various, not prepublished, patent applications that go back to the applicant, a blanket, in particular a bedspread, is now also proposed, in which spherical fiber aggregates made of spherically entangled fibers are used as the filling. These fiber aggregates make it very easy to design such a blanket.

Eine Bettdecke soll im wesentlichen ein stehendes Luftpolster zwischen einer die Decke benutzenden Person und der Umwelt schaffen. Ist dabei zwischen den Füllungsbestandteilen sehr viel Luft vorhanden, so wirkt die Decke durch die - unbewegte - Luft wärmeisolierend.A duvet is essentially intended to create a standing air cushion between a person using the blanket and the environment. If there is a lot of air between the filling components, the blanket has a heat-insulating effect due to the - still - air.

Bei abgesteppten Decken, bei denen im Bereich der Steppung das eine Deckblatt unmittelbar auf dem anderen Deckblatt - oder wie bei der Decke gemäß dem DE-U-7.715.468 nur das Zwischenblatt zwischen sich einschließend - zu liegen kommt, besteht an den Steppnähten ein Bereich erhöhter Wärmeverluste, es besteht dort eine sogenannte Kältebrücke.For quilted ceilings, where one cover sheet is directly on top of the other in the area of the quilting Cover sheet - or as in the case of the ceiling according to DE-U-7.715.468 only including the intermediate sheet between them - there is an area of increased heat loss at the stitching seams, there is a so-called cold bridge.

Andererseits muß aber insbesondere bei Bettdecken auch ein Austausch bzw. Durchgang für Transpirationen und Gase, die der menschliche Körper absondert, durch die Decke möglich sein.On the other hand, it must also be possible to exchange or pass through the blanket for perspiration and gases that the human body secretes, particularly in the case of bed covers.

Aus der WO-85/01201 ist ein Schlafsack bekannt der zwei übereinander liegende, jeweils gesteppte Decken aufweist, bei denen auf der vom Körper abgewandten Seite der Decke jeweils oberhalb des oberen Deckblattes eine perforierte, reflektierende Schicht angeordnet ist. Weiterhin ist zwischen den beiden Decken, deren Steppungen gegeneinander versetzt sind, noch Luft vorhanden. Beide Decken sind mit einem aus Kunststoff-Fasern bestehenden Füllung gefüllt. Über den beiden Decken ist eine feuchtigkeitsabstoßende Schicht aus Polyamid angeordnet. Die eine der beiden perforierten Schichten liegt somit zwischen den beiden Decken, während die andere zwischen der oberen Decke und der feuchtigkeitsabstoßenden Schicht angeordnet ist.From WO-85/01201 a sleeping bag is known which has two superimposed, each quilted blanket, in which a perforated, reflective layer is arranged on the side of the blanket facing away from the body above the upper cover sheet. There is still air between the two ceilings, the quilting of which is offset from one another. Both blankets are filled with a filling made of plastic fibers. A moisture-repellent layer made of polyamide is arranged above the two ceilings. One of the two perforated layers thus lies between the two blankets, while the other is arranged between the top blanket and the moisture-repellent layer.

Durch die Verwendung einer perforierten Schicht kann ein gleichmäßiger Luftaustausch durch diese Schicht hindurch erfolgen.Through the use of a perforated layer, an even exchange of air can take place through this layer.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Decke zu schaffen, bei der der Wärmetransport durch diese Decke merklich vermindert wird.The invention has for its object to provide a generic blanket in which the heat transfer through this blanket is significantly reduced.

Diese Aufgabe wird durch eine Decke gemäß Anspruch 1 gelöst. Die Erfindung geht von der Überlegung aus, daß eine wärmedichtere Decke erhalten werden kann, wenn durch die Decke überhaupt keine Feuchtigkeit, Gase od.dgl. hindurchdringen kann. Bei der erfindungsgemäßen Decke besteht deshalb das Zwischenblatt aus einer dünnen Folie, die längliche Schlitze aufweist.This object is achieved by a blanket according to claim 1. The invention is based on the consideration that a more heat-resistant blanket can be obtained if no moisture, gases or the like are present through the blanket at all. can penetrate. In the blanket according to the invention, therefore, the intermediate sheet consists of a thin film which has elongated slots.

Diese Folie verringert die Möglichkeit des schnellen Luftaustausches durch die Decke hindurch, gestattet jedoch einen ausreichenden Durchgang für Feuchtigkeit und Gase.This film reduces the possibility of rapid air exchange through the ceiling, but allows sufficient passage for moisture and gases.

Eine solche Folie besteht z.B. aus einem Kunststoff, da eine Kunststoffolie selbst gasdicht ist, durch die Schlitze jedoch noch in eingeschränktem Maße ein Austausch von Luft und Feuchtigkeit stattfinden kann.Such a film is e.g. from a plastic, since a plastic film is itself gas-tight, but the slots can still exchange air and moisture to a limited extent.

Gemäß einer anderen Ausführungsform ist diese Folie eine Metallfolie, die den Vorteil hat, daß sie die auf sie auftreffende Wärme zurückstrahlt. Eine Metallfolie ist jedoch sehr empfindlich gegen mechanische Belastung und kann deshalb bei längerem Gebrauch allmählich zerstört werden.According to another embodiment, this foil is a metal foil, which has the advantage that it reflects the heat that strikes it. However, a metal foil is very sensitive to mechanical stress and can therefore be gradually destroyed over a long period of use.

Bevorzugt wird deshalb eine Folie aus einem beschichteten Kunststoff, insbesondere eine mit Aluminium bedampfte Kunststoffolie, verwendet. Diese vereint die Vorteile der Kunststoffolie mit denen der Metallfolie.A film made of a coated plastic, in particular a plastic film coated with aluminum, is therefore preferably used. This combines the advantages of plastic foil with those of metal foil.

Der Wärmeverlust durch die Decke hindurch wird insbesondere auch im Bereich von Steppnähten verringert, da die in der Decke angeordnete Folie sowohl die Wärmekonvektion behindert, als auch die Wärme wieder zurückstrahlt.The heat loss through the blanket is reduced especially in the area of quilting seams, because the Foil arranged in the ceiling both hinders heat convection and also radiates the heat back again.

Weist die Folie im Bereich der Steppung keine Schlitze auf, so kann der Wärmeverlust in diesem Bereich nochmals verringert werden.If the film has no slits in the area of the quilting, the heat loss in this area can be reduced again.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den Unteransprüchen und aus im Folgenden anhand der Zeichnung beschriebenen Ausführungsbeispielen.Further details and advantages of the invention emerge from the subclaims and from the exemplary embodiments described below with reference to the drawing.

The two Figures 1 and 2 each show schematically a section through a quilt 1, which consists of two cover sheets 2 and 3, a filling arranged between them 4 and a film 5 arranged between the cover sheets 2 and 3. This film 5 is discussed in more detail below.

Diese Decke 1 ist hier abgesteppt. Es könnte aber auch eine ungesteppte Decke 1 sein.This blanket 1 is stitched here. But it could also be a quilted blanket 1.

Die Füllung 4 besteht - hier - aus kugelförmigen Faseraggregaten aus sphärisch verwickelten Fasern, die z.B. einen Durchmesser von 3 bis 15 mm aufweisen können. Anstelle der Faseraggregate kann die Füllung 4 aber auch aus herkömmlichen Füllmaterialien wie Daunen, Federn, Faservlies od.dgl. bestehen. Es kann auch ein Gemisch verschiedener Füllmaterialien vorliegen. In der Zeichnung sind die einzelnen die Füllung 4 bildenden Faseraggregate größer dargestellt. In Wirklichkeit sind viel mehr Faseraggregate in der Decke 1 angeordnet, als sich hier darstellen läßt. Auch sind die Faseraggregate räumlich enger aufeinander angeordnet, wobei sogar einzelne Fasern eines Aggregates in ein anderes Aggregat hineindringen können.The filling 4 consists - here - of spherical fiber aggregates made of spherically entangled fibers, which e.g. can have a diameter of 3 to 15 mm. Instead of the fiber aggregates, the filling 4 can also be made of conventional filling materials such as down, feathers, nonwoven or the like. consist. A mixture of different filling materials can also be present. In the drawing, the individual fiber aggregates forming the filling 4 are shown larger. In reality, much more fiber aggregates are arranged in the ceiling 1 than can be represented here. The fiber aggregates are also spatially closer to one another, and even individual fibers of one aggregate can penetrate into another aggregate.

Bei der Ausführungsform gemäß Figur 1 ist die Folie 5 mittig zwischen den beiden Deckblättern 2 und 3 der Decke 1 angeordnet, wobei sich beidseits der Folie 5 etwa gleichviel Füllmaterialien 4 befinden. Auf beiden Seiten dieser Folie 5 können verschiedene Füllmaterialien 4 angeordnet sein; auch kann es sich dabei jeweils wiederum um Gemische handeln.In the embodiment according to FIG. 1, the film 5 is arranged centrally between the two cover sheets 2 and 3 of the ceiling 1, with about the same amount of filling materials 4 on both sides of the film 5. Different filling materials 4 can be arranged on both sides of this film 5; it can also be a mixture.

Die Folie 5 kommt bei der Ausführungsform gemäß Figur 1 nur im Bereich der Steppung mit den beiden Deckblättern 2 und 3 in Kontakt, ansonsten befinden sich zwischen der Folie 5 und dem jeweiligen Deckblatt 2 bzw. 3 Füllmaterialien 4, hier Faseraggregate.In the embodiment according to FIG. 1, the film 5 only comes into contact with the two cover sheets 2 and 3 in the area of the quilting, otherwise there are 2 or 3 filling materials 4, here fiber aggregates, between the film 5 and the respective cover sheet.

Bei der Ausführungsform gemäß Figur 1 ist es gleich, welche Seite der Decke 1 auf dem Körper zu liegen kommt, da die Decke 1 symmetrisch ausgebildet ist.In the embodiment according to FIG. 1, it does not matter which side of the blanket 1 comes to lie on the body, since the blanket 1 is symmetrical.

Bei der Ausführungsform gemäß Figur 2 ist die Folie 5 benachbart zu dem einen Deckblatt 2 angeordnet. Hier liegt die Folie 5 sogar unmittelbar auf diesem Deckblatt 2 auf. Alternativ könnte zwischen diesem Deckblatt 2 und der Folie 5 noch eine dünne Schicht aus Füllmaterialien 4 zu liegen kommen. Mit dem anderen Deckblatt 3 kommt die Folie 5 gemäß Figur 2 nur im Bereich der Steppung in Kontakt, ansonsten sind zwischen der Folie 5 und dem anderen Deckblatt 3 nur Faseraggregate der Füllung 4 angeordnet.In the embodiment according to FIG. 2, the film 5 is arranged adjacent to the one cover sheet 2. Here the film 5 even lies directly on this cover sheet 2. Alternatively, could be between this cover sheet 2 and the film 5 a thin layer of filling materials 4 come to rest. The film 5 according to FIG. 2 only comes into contact with the other cover sheet 3 in the area of the quilting, otherwise only fiber aggregates of the filling 4 are arranged between the film 5 and the other cover sheet 3.

Eine Decke 1 gemäß der Ausführungsform nach Figur 2 kann nun mit der Folie 5 unten oder oben liegend benutzt werden.A blanket 1 according to the embodiment according to FIG. 2 can now be used with the film 5 at the bottom or at the top.

Liegt die Folie 5 unten, so staut sich unterhalb der Decke 1 mehr Wärme, Feuchtigkeit usw., was dann vorteilhaft ausgenutzt werden kann, wenn es sehr kalt ist oder wenn die die Decke 1 benutzende Person - z.B. wegen einer Grippe od.dgl. - schwitzen will. Die Folie 5, insbesondere wenn sie metallisiert ist, strahlt die Wärme sehr gut wieder zurück.If the film 5 is at the bottom, then more heat, moisture etc. accumulates under the ceiling 1, which can be used advantageously when it is very cold or when the person using the ceiling 1 - e.g. because of flu or the like - wants to sweat. The film 5, particularly if it is metallized, radiates the heat back very well.

Liegt die Folie 5 oben, so können Feuchtigkeit und Wärme in die Decke 1 hineindringen. Durch die obenliegende geschlitzte Folie 5 kann Feuchtigkeit entweichen. Die Folie 5, insbesondere, wenn diese metallisiert ist, strahlt die Wärme in der Decke 1 wieder in Richtung auf den darunterliegen Menschen zurück.If the film 5 is on top, moisture and heat can penetrate into the ceiling 1. Moisture can escape through the slotted film 5 on top. The film 5, especially if it is metallized, radiates the heat in the ceiling 1 back towards the people underneath.

Die Figuren 3 bis 8 zeigen nun verschiedene Ausbildungen der Folie 5. Diese Folie 5 besteht gemäß einer bevorzugten Ausführungsform aus einer Kunststoffolie, die darüberhinaus mit Metall bedampft sein kann. Als Metall wird dabei vorzugsweise Aluminium verwendet.FIGS. 3 to 8 now show different designs of the film 5. According to a preferred embodiment, this film 5 consists of a plastic film which can also be vapor-coated with metal. Aluminum is preferably used as the metal.

Längliche, in der Folie 5 angeordnete und diese ganz durchdringende Schlitze 6 sind in Reihen angeordnet, wobei zwischen Reihen in Längsrichtung der Schlitze 6 und Reihen quer oder schräg dazu unterschieden wird.Elongated slots 6 arranged in the film 5 and penetrating them completely are arranged in rows, a distinction being made between rows in the longitudinal direction of the slots 6 and rows transversely or obliquely thereto.

Das Schlitzen von Folien 5 ist allgemein bekannt, es wird hierzu z.B. auf die DE-A-1.915.523 verwiesen.The slitting of foils 5 is generally known, e.g. referred to DE-A-1.915.523.

Figur 3 zeigt nun Schlitze 6, die sowohl in ihrer Längsrichtung gesehen in Reihen angeordnet sind, als auch senkrecht dazu. Senkrecht zueinander angeordnete Schlitze 6 weisen hier einen Abstand auf, der etwa der Schlitzlänge entspricht, während der Abstand der Schlitze 6 voneinander in Längsrichtung etwa der halben Schlitzlänge entspricht. Schlitzfreie Bereiche zwischen den Schlitzen 6 in Längserstreckung derselben gesehen sind hier auf Linien angeordnet, die senkrecht auf der Längserstreckung der Schlitze 6 stehen.Figure 3 now shows slots 6, which are arranged both in rows seen in their longitudinal direction, as well as perpendicular to them. Slots 6 arranged perpendicular to one another have a distance here which corresponds approximately to the slot length, while the distance of the slots 6 from one another corresponds in the longitudinal direction to approximately half the slot length. Slot-free areas between the slots 6 seen in the longitudinal extent thereof are arranged here on lines that are perpendicular to the longitudinal extent of the slots 6.

Schlitze 6 in einer solchen Anordnung bleiben auch dann im wesentlichen geschlossen, wenn auf die Decke 1 und damit auch auf die Folie 5 ein mechanischer Zug längs und / oder quer zu der Längserstreckung der Schlitze 6 ausgeübt wird.Slots 6 in such an arrangement remain essentially closed even when a mechanical pull is exerted on the ceiling 1 and thus also on the film 5 along and / or transversely to the longitudinal extent of the slots 6.

Figur 4 zeigt eine Anordnung von Schlitzen 6 die in Längsrichtung gesehen in Reihen angeordnet sind, wobei die Schlitze 6 benachbarter Reihen jeweils auf Lücke angeordnet sind, d.h., die Schlitze 6 benachbarter Reihen sind jeweils dort angeordnet, wo die erste Reihe schlitzfrei ist. Schlitze 6 benachbarter Reihen sind hier also versetzt zueinander angeordnet. Der Abstand der Längsreihen voneinander kann zwischen einer halben und einer ganzen Schlitzlänge betragen, das gleiche gilt für den Abstand der einzelnen Schlitze 6 voneinander in einer Längsreihe. Schlitzfreie Bereiche sind hier auf Linien angeordnet, die mit der Längserstreckung der Schlitze 6 einen Winkel von etwa 30° einschließen.Figure 4 shows an arrangement of slots 6 which are arranged in rows in the longitudinal direction, the slots 6 of adjacent rows being arranged in a gap, i.e. the slots 6 of adjacent rows are each arranged where the first row is slot-free. Slots 6 of adjacent rows are here offset from one another. The distance between the longitudinal rows from one another can be between half and a whole slot length, the same applies to the distance of the individual slots 6 from one another in a longitudinal row. Slot-free areas are arranged here on lines which enclose an angle of approximately 30 ° with the longitudinal extent of the slots 6.

Durch das versetzte Anordnen der Schlitze 6 können sich diese bei einem mechanischen Zug quer zu ihrer Längserstreckung öffnen, wobei sich die Stege 7 zwischen den Schlitzen 6 aus der Ebene heraus verwölben. Durch eine solche Folie 5 kann deshalb bei Bedarf - wenn die Folie 5 quer zur Längserstreckung gestreckt wird - ein größerer Luftaustausch stattfinden. Dieses Strecken der Folie 5 kann dadurch erfolgen, daß die gesamte Decke 1 gestreckt wird, aber auch insbesondere dadurch, daß ein Druck senkrecht auf die Folie 5 ausgeübt wird, indem z.B. die Decke 1 an einer oder mehreren Stellen aus ihrer Ebene herausgedrückt wird.The staggered arrangement of the slots 6 allows them to open transversely to their longitudinal extent in the event of a mechanical pull, the webs 7 arching out of the plane between the slots 6. Such a film 5 can therefore, if necessary - if the film 5 is stretched transversely to the longitudinal extent - a larger air exchange takes place. This stretching of the film 5 can be carried out by stretching the entire ceiling 1, but also in particular by exerting pressure perpendicularly on the film 5, e.g. the ceiling 1 is pressed out of its plane at one or more points.

Figur 5 zeigt bogenförmige Schlitze 6, deren Abstand in Längserstreckung der Schlitze 6 gesehen etwa einer Schlitzlänge entspricht, während der Abstand der Schlitze 6 quer dazu gesehen größer als eine Schlitzlänge ist. Der Bogen entspricht hier etwa einem sechstel bis einem zwanzigstel einer Kreislinie. Bei solchen Schlitzen 6 können die Teile des Füllmaterials 4 eine durch den Schlitz 6 gebildete U-förmige Schuppe etwas aus der Folienebene herauswölben, insbesondere, wenn eine Belastung senkrecht auf die Fläche der Decke 1 und der Folie 5 ausgeübt wird.FIG. 5 shows arcuate slots 6, the spacing of which, viewed in the longitudinal extent of the slots 6, is approximately one Slot length corresponds, while the distance of the slots 6 seen transversely thereto is greater than a slot length. The arc here corresponds to approximately one sixth to one twentieth of a circular line. In the case of such slots 6, the parts of the filling material 4 can bulge a U-shaped scale formed by the slot 6 somewhat out of the film plane, in particular if a load is exerted perpendicularly on the surface of the ceiling 1 and the film 5.

Figur 6 zeigt eine Anordnung von Schlitzen 6, bei der sich Längsreihen von Schlitzen 6 in dieser Längserstreckung mit dazu parallelen Reihen abwechseln, in denen die Schlitze 6 senkrecht zu dieser Längserstreckung angeordnet sind. Dabei liegen die quer liegenden Schlitze 6 in einer Linie, die mittig durch die "Längs"-Schlitze 6 hindurch geht. Dagegen zeigt Figur 7 eine ähnliche Anordnung, wobei hier die "Quer"-Schlitze 6 jeweils in Querreihen liegen, die die Längsreihen in schlitzfreien Bereichen schneiden.FIG. 6 shows an arrangement of slots 6, in which longitudinal rows of slots 6 alternate in this longitudinal extent with rows parallel thereto, in which the slots 6 are arranged perpendicular to this longitudinal extent. The transverse slots 6 lie in a line which passes through the "longitudinal" slots 6 in the middle. In contrast, FIG. 7 shows a similar arrangement, with the "transverse" slots 6 each lying in transverse rows that intersect the longitudinal rows in slot-free areas.

Figur 8 zeigt eine der Figur 7 ähnliche Ausbildung, nur sind hier jeweils zwei Schlitze 6 paarweise angeordnet. Jedes Paar von Schlitzen 6 weist zwischen sich einen Steg 7 auf. Diese Stege 7 können durch Teile des Füllmaterials 4 leicht ausgewölbt werden, wenn die Decke 1 und die damit die in dieser angeordnete Folie 5 nicht in ihrer Erstreckungsebene gespannt ist.FIG. 8 shows a configuration similar to FIG. 7, only two slots 6 are arranged in pairs here. Each pair of slots 6 has a web 7 between them. These webs 7 can be slightly arched out by parts of the filling material 4 if the ceiling 1 and thus the film 5 arranged in it are not stretched in their plane of extension.

Die Schlitze 6 können eine Länge zwischen 2 und 10 mm aufweisen. Je kleiner die Länge der Schlitze 6 ist, desto wärmedichter wird die Decke 1, desto weniger Feuchtigkeit kann aber auch durch die Decke 1 hindurchdringen. Der Abstand benachbarter Schlitze 6 in Längsrichtung kann etwa einem Halben bis einem Ganzen der Schlitzlänge entsprechen. Ebenso kann der Abstand benachbarter Schlitze 6 quer zur Längserstreckung der Schlitze 6 etwa einem Halben bis einem Ganzen der Schlitzlänge entsprechen.The slots 6 can have a length between 2 and 10 mm. The smaller the length of the slots 6, the more heat-proof the blanket 1 becomes, but the less moisture can also penetrate through the blanket 1. The distance between adjacent slots 6 in the longitudinal direction can correspond to about half to a whole of the slot length. Likewise, the distance between adjacent slots 6 can correspond approximately to half to a whole of the slot length transversely to the longitudinal extent of the slots 6.

Je nach Schlitzform und -ausbildung ist hier ein Optimum gemäß dem gewünschten Ergebnis festzulegen.Depending on the shape and shape of the slot, an optimum is to be determined according to the desired result.

Die Schlitze 6 werden in die Folie 5 eingeschnitten, ohne daß Material weggenommen wird. Im unbelasteten Zustand der Folie 5 sind deshalb die Schlitze 6 geschlossen. Im Gebrauchszustand der Decke 1, wenn diese also mit Füllmaterial 4 gefüllt ist, drückt dieses ungleichmäßig auf die an die Schlitze 6 anschließenden Bereiche der Folie 5, sodaß diese geringfügig unter mehr oder weniger weiten Öffnen der Schlitze 6 aus der Folienebene herausgedrückt werden können.The slots 6 are cut into the film 5 without material being removed. In the unloaded state the film 5, the slots 6 are therefore closed. When the blanket 1 is in use, when it is filled with filler material 4, it presses unevenly on the areas of the film 5 adjoining the slots 6, so that they can be pushed out of the film level slightly with more or less wide opening of the slots 6.

Die Durchlässigkeit der Folie 5 hängt auch von der gewählten Form und Anordnung der Schlitze 6 ab, wobei dem Fachmann auch andere, hier nicht gezeigte Schlitzformen und -anordnungen bekannt sind.The permeability of the film 5 also depends on the selected shape and arrangement of the slots 6, with other slot shapes and arrangements not shown here being known to the person skilled in the art.

Um die bekannten, insbesondere im Bereich der Steppung vorhandenen Kältebrücken zu vermeiden bzw. deren Wirkung zu verringern, weist gemäß einer nicht gesondert dargestellten Ausführungsform die Folie 5 im Bereich der Steppung, in deren unmittelbaren Umgebung in der Regel auch kein Füllmaterial 4 vorliegt, keine Schlitze 6 auf. Hier wird also verhindert, daß Gase und Feuchtigkeit durch die Decke 1 hindurchdringen können, wenngleich die Folie 5 durch das Durchnähen perforiert wird. Es empfiehlt sich eine Folie 5 zu verwenden, die von ihrem Material her in der Lage ist, daß sie sich an die Nähfäden andrückt, um so nur einen Durchgang zwischen und in den Nähfäden zu gestatten.In order to avoid the known cold bridges, in particular in the area of the quilting, or to reduce their effect, according to an embodiment which is not shown separately, the film 5 has no slits in the area of the quilting, in the immediate vicinity of which there is generally also no filler material 4 6 on. Here it is prevented that gases and moisture can penetrate through the cover 1, although the film 5 is perforated by the stitching. It is advisable to use a film 5 which is capable of pressing against the sewing threads in order to allow only one passage between and in the sewing threads.
