Abstract

A mattress cover as claimed in claim 1 is made in such a way that the upper and lower faces differ in that an upper face material with the allergen-proof but water vapour-permeable barrier layer is fitted and a lower face material is merely mite-proof, in order on the one hand to provide effective protection against allergens and on the other to provide good durability with adequate air and water vapour permeability and permit easy cleaning.

Description

Matratzenbezug Mattress cover
Die Erfindung betrifft einen Matratzenbezug nach dem Oberbegriff des An¬ spruchs 1.The invention relates to a mattress cover according to the preamble of claim 1.
Matratzenbezüge aus einem einheitlich durchgängigen Bezugsstoff, etwa aus Baumwolle, sind für den allgemeinen Gebrauch seit langem bekannt, um in einer durch Knöpfe, Druckknöpfe oder Reißverschlüsse zu schließenden Form eine Matratze vollständig einzuhüllen oder auch in einer die Matratzenuntersei¬ te zumindest im wesentlichen offen belassenen Form deren Oberseite und Randseiten abzudecken. Dabei geht es traditionell um einen unter Sauberkeits¬ und Hygienegesichtspunkten abnehmbaren und waschbaren Bezug.Mattress covers made of a uniformly continuous cover material, such as cotton, have long been known for general use, in order to completely cover a mattress in a form to be closed by buttons, push buttons or zippers, or also in a form which at least essentially leaves the mattress underside open to cover their top and edge sides. Traditionally, this is about a cover that is removable and washable from a cleanliness and hygiene point of view.
Weitergehende Anforderungen an einen Matratzenbezug haben sich aus der Erkenntnis ergeben, daß sich auch bei sauberer und hygienischer Haushalts¬ führung normalerweise Hausmilben in großer Zahl in Matratzen ansiedeln, die in diesem Lebensraum einerseits von dem Schlafklima des Menschen unterFurther requirements for a mattress cover have arisen from the knowledge that even with clean and hygienic housekeeping, house mites usually settle in mattresses in large numbers, which in this habitat depend on the one hand on the sleeping climate of humans
ORIGINAL UNTERLAGEN Nutzung der vom Menschen abgegebenen Wärme und Feuchtigkeit mitprofitie¬ ren, andererseits sich vollständig von den winzigen vom Menschen abgesto¬ ßenen Hautschuppen ernähren. Insbesondere der Kot dieser Hausmilben ist als eines der schwerstwiegenden Allergene identifiziert, wobei ein Schutz ge¬ gen solche Allergene nicht nur für die große und wachsende Zahl der an der "Hausstauballergie" erkrankten Menschen, sondern auch für weite Kreise von Bedeutung ist, deren Empfindlichkeit noch nicht zu Körperreaktionen von der Schwere einer Krankheit geführt hat.ORIGINAL DOCUMENTS Benefit from the use of the heat and moisture given off by humans, and on the other hand, they feed entirely on the tiny skin scales rejected by humans. The feces of these house mites in particular are identified as one of the most serious allergens, and protection against such allergens is important not only for the large and growing number of people suffering from "house dust allergy", but also for large groups whose sensitivity is still important has not led to body reactions from the severity of an illness.
Zum Schutz gegen solche Allergene hat es bereits Entwicklungen gegeben, die darauf abzielten, eine Matratze hermetisch einzuschließen. Damit läßt sich zwar der Liegekomfort einer Matratze im Sinne einer weichen Körperauflage erhalten, nicht aber deren klimatische Wirkung, da über die Matratze norma¬ lerweise etwa ein Drittel der vom Körper dampfförmig abgegebenen Körper¬ feuchtigkeit abgeführt wird. Eine vollkommen versiegelte Matratze führt also zu einer Luft- und Dampfsperre mit einem entsprechenden Feuchtigkeitsstau am Körper, an der Bekleidung und dem Bettlaken. Dies führt zu einem ungesunden und unbehaglichen Schwitzen, aber auch zu Feuchtigkeitsbelastungen im Bereich der umgebenden Textilien.To protect against such allergens, there have already been developments aimed at hermetically enclosing a mattress. This means that the lying comfort of a mattress in the sense of a soft body support can be maintained, but not its climatic effect, since about a third of the body moisture released by the body in vapor form is normally removed via the mattress. A completely sealed mattress leads to an air and vapor barrier with a corresponding moisture build-up on the body, clothing and bed sheet. This leads to unhealthy and uncomfortable sweating, but also to moisture in the area of the surrounding textiles.
Im Sinne einer luft- und dampfdurchlässigen Körperauflage sind bereits Ma¬ tratzenbezüge aus einem thermisch-mechanisch verdichteten Baumwollgewe¬ be, insbesondere Inlettgewebe, angeboten worden. Nachdem nämlich durch Untersuchungen bereits festgestellt wurde, daß das Inlettgewebe dicht genug ist, mit seiner feinfädigen körperbindigen Form Hausmilben mit einer Körper¬ größe von etwa 20 μm auszusperren, bestand hier die Hoffnung, durch Ver- dichtung auch eine Sperre gegen die Allergene, d.h. den Milbenkot, mit einer Größe von unter 1 μm zu schaffen. Hierin kann allerdings insofern keine be¬ friedigende Lösung gesehen werden, als eine solche thermisch-mechanische Verdichtung des Gewebes allenfalls als Neuware Barriereeigenschaften auf¬ weisen kann, die aber durch Gebrauch und insbesondere durch Waschen ver¬ lorengehen.In the sense of an air and vapor permeable body support, mattress covers made of a thermo-mechanically compressed cotton fabric, in particular ticking fabric, have already been offered. After it had already been found through investigations that the ticking tissue was dense enough to block out house mites with a body size of about 20 μm with its fine, thread-like shape, there was hope that seal to create a barrier against the allergens, ie the mite droppings, with a size of less than 1 μm. However, this cannot be seen as a satisfactory solution insofar as such a thermal-mechanical compression of the fabric can at best have barrier properties as new goods, but which are lost through use and in particular through washing.
Nach einem anderen Vorschlag (DE 40 27 798 C2) kann die Verwendung einer Polyurethanschicht, verstärkt durch ein textiles Material wie z.B. ein Polyester¬ gewirk, zu einem dampfdurchlässigen, aber wasserdichten Matratzenüberzug vorgesehen werden. Ein solcher Überzug würde allerdings sehr schnell un¬ brauchbar, weil aufgenommener Wasserdampf in dem wasserdichten Überzug kondensiert und dann nicht entweichen kann. Es fehlt auch eine hinreichende Luftdurchlässigkeit.According to another proposal (DE 40 27 798 C2) the use of a polyurethane layer reinforced by a textile material such as e.g. a polyester knitted fabric can be provided for a vapor-permeable but waterproof mattress cover. Such a coating would, however, very quickly become unusable because absorbed water vapor condenses in the waterproof coating and then cannot escape. Adequate air permeability is also lacking.
Aufgabe der Erfindung ist es, einen Matratzenbezug zu schaffen, der in her¬ kömmlicher Weise luft- und dampfdurchlässig ist und im Sinne von Sauberkeit und Hygiene waschbar ist, der dabei aber eine wirksame und beständige Bar¬ riere gegen Allergene aus der Matratze schafft.The object of the invention is to provide a mattress cover which is permeable to air and steam in a conventional manner and is washable in the sense of cleanliness and hygiene, but which creates an effective and durable barrier against allergens from the mattress.
Gemäß der Erfindung wird diese Aufgabe von dem Oberbegriff des An¬ spruchs 1 ausgehend mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.According to the invention, this object is achieved on the basis of the preamble of claim 1 with the characterizing features of claim 1.
Es hat sich als wichtig für die Gebrauchseigenschaften eines solchen Matrat¬ zenbezugs herausgestellt, daß dieser oberseitig und unterseitig unterschiedlich gestaltet ist, wobei eine allergendichte Ausbildung der Oberseite zugewiesen wird. Dies beschränkt die besondere allergendichte Ausstattung auf den kriti¬ schen, als Auflagefläche für den Körper des Benutzers bestimmten und hin¬ sichtlich des Durchtritts von Allergenen nach oben gefährlichen Bereich. Dabei wird die allergendichte Schicht innen (rückseitig) an dem Oberseitenmaterial vorgesehen, so daß die körperseitige Oberfläche aus einem herkömmlichen, hautfreundlichen Material wie etwa Baumwolle auszubilden ist, welches auch Feuchtigkeit absorbiert.It has been found to be important for the usage properties of such a mattress cover that it differs on the top and bottom is designed, with an allergy-tight training is assigned to the top. This limits the special allergen-proof equipment to the critical area, which is intended as a support surface for the body of the user and which is dangerous in terms of the passage of allergens. The allergen-tight layer is provided on the inside (on the back) of the top material, so that the body-side surface is to be formed from a conventional, skin-friendly material such as cotton, which also absorbs moisture.
Demgegenüber wird das Unterseitenmaterial lediglich milbendicht ausgelegt, um Einwanderungen (und Auswanderungen) einer Milbenpopulation bestmög¬ lich zu verhindern. Ein solches Unterseitenmaterial kann damit aber sehr viel luftdurchlässiger ausgebildet sein, so daß die innenliegende Matratze von der Unterseite her gut belüftet ist. Feuchtigkeits- und Wärmestaus, die in außen¬ seitig ringsum weitgehend versiegelten Matratzen auftreten können und dann auch durch Schimmelpilzbildung weitere Gesundheitsgefahren heraufbeschwö¬ ren, lassen sich auf diese Weise unterbinden.In contrast, the underside material is only designed to be mite-tight in order to prevent immigration (and emigration) of a mite population as effectively as possible. Such an underside material can, however, be made much more permeable to air, so that the inside mattress is well ventilated from the underside. Moisture and heat build-up, which can occur in mattresses that are largely sealed on the outside and then cause further health hazards due to the formation of mold, can be prevented in this way.
Vorteilhaft kann das Oberseitenmaterial des Matratzenbezugs aus einem ein¬ lagigen Stoff bestehen, in dem ein Baumwollgewebe auf seiner Rückseite direkt eine allergendichte Schicht als Beschichtung trägt. Angesichts der für eine Dampfdurchlässigkeit wichtigen geringen Dicke einer solchen Beschichtung ist dabei ein Baumwollgewebe an der Beschichtungsseite regelmäßig glättend zu bearbeiten. Der Vorteil eines solchen einlagigen Bezugsstoffs im Vergleich zu einer zweilagigen Ausbildung von Bezugsstoff und Barriereschicht liegt in der Möglichkeit, die Barriereschicht nicht selbsttragend ausbilden zu müssen, so daß sie funktionsgerecht, insbesondere im Sinne einer Dampfdurchlässigkeit, fein ausgebildet sein kann und dabei im Sinne einer ausreichenden Robustheit das Baumwollgewebe als Träger nutzt. Ein solcher Bezugsstoff läßt sich waschbar ausbilden. Daneben ist die einlagige Ausführungsform zweckmäßig zur Vermeidung eines Zwischenraums zwischen Außenstoff und Barriere¬ schicht, in dem sich Milben ansiedeln könnten.The top material of the mattress cover can advantageously consist of a single-layer material in which a cotton fabric has an allergy-tight layer as a coating on its back. In view of the small thickness of such a coating, which is important for vapor permeability, a cotton fabric on the coating side must be regularly smoothed. The advantage of such a single-layer cover fabric compared to a two-layer design of cover fabric and barrier layer lies in the possibility that the barrier layer does not have to be self-supporting that it can be fine-tuned in a functional manner, in particular in the sense of vapor permeability and thereby uses the cotton fabric as a carrier in the sense of sufficient robustness. Such a cover fabric can be made washable. In addition, the single-layer embodiment is expedient to avoid an intermediate space between the outer fabric and the barrier layer, in which mites could settle.
Besonders vorteilhaft ist eine vollständige Trennbarkeit des Matratzenbezugs in zwei einerseits das Oberseitenmaterial umfassende und andererseits das Unterseitenmaterial umfassende Teile, so daß beispielsweise das sehr viel stärker beanspruchte Oberseitenmaterial häufiger gewaschen werden kann. Dabei ist es dann nicht erforderlich, die Matratze aufzunehmen und den Ma¬ tratzenbezug als Ganzes abzuziehen, vielmehr kann eine Gesamtwäsche des Matratzenbezugs in groben Zeitintervallen erfolgen, während das Oberseiten¬ material zwischendurch in kürzeren Zeitabständen zu waschen ist.It is particularly advantageous that the mattress cover can be completely separated into two parts, which on the one hand comprise the top material and on the other hand include the bottom material, so that, for example, the top material, which is subjected to much greater stress, can be washed more frequently. It is then not necessary to take up the mattress and remove the mattress cover as a whole; rather, the mattress cover can be washed overall at rough time intervals, while the top material is to be washed in between at shorter intervals.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. In der Zeichnung zeigen in jeweils schemati¬ sierter Wiedergabe:An embodiment of the invention is shown in the drawing and will be described in more detail below. In the drawing, each shows a schematic representation:

Fig. 4 Schnitt entsprechend Fig. 3 durch einen abgewandeltenFig. 4 section corresponding to Fig. 3 by a modified
Matratzenbezug. Der in Fig. 1 insgesamt mit 1 bezeichnete und in seiner Verwendungsform, z.B. auf eine Matratze aufgezogene Matratzenbezug, ist typischerweise für eine einteilige Einzelmatratze vorgesehen. Es versteht sich allerdings, daß ein sol¬ cher Matratzenbezug ebenso eine einteilige Matratze eines ("französischen") Doppelbettes, zwei Matratzen eines Doppelbettes gemeinsam oder auch drei oder gar sechs Matratzen der früher gebräuchlicheren (dreigeteilten) Form auf¬ nehmen kann.Mattress cover. The mattress cover, generally designated 1 in FIG. 1 and used in its form of application, for example on a mattress, is typically provided for a one-piece single mattress. It goes without saying, however, that such a mattress cover can also accommodate a one-piece mattress of a ("French") double bed, two mattresses of a double bed together, or three or even six mattresses of the previously more common (three-part) form.
Der Matratzenbezug besteht aus zwei vollkommen voneinander trennbaren Teilen, nämlich einem Oberteil 2 und einem Unterteil 3, wobei Oberteil und Unterteil über einen längs Randseiten 4,5 umlaufenden teilbaren Reißverschluß 6 miteinander verbunden sind. Ein solcher Reißverschluß bietet eine robuste, flexible, durchgängige Textilverbindung, die hier gefordert ist. Grundsätzlich können aber auch andere Verbindungen wie Haft- oder Knopfleisten, etwa in Kombination mit Dichtsäumen oder -streifen, Anwendung finden.The mattress cover consists of two parts which can be completely separated from one another, namely an upper part 2 and a lower part 3, the upper part and lower part being connected to one another via a separable zipper 6 which runs around the longitudinal edges 4, 5. Such a zipper offers a robust, flexible, continuous textile connection, which is required here. In principle, however, other connections such as adhesive strips or button strips, for example in combination with sealing seams or strips, can also be used.
Zwei weitere Reißverschlußseiten (Reißverschlußhälften 7 bzw. 8) sind zusätz¬ lich am Unterteil 3 angebracht und verlaufen parallel zum Reißverschluß 6, so daß eine Seite des Reißverschlusses 6, die am Oberteil 2 befestigt ist, mit den Reißverschlußseiten 7 oder 8 verbunden werden kann, wenn eine Matratze geringerer Matratzenhöhe bezogen werden soll. Ungenauigkeiten oder Verän¬ derungen in der Matratzenhöhe, mehr noch Unsicherheiten eines Matratzen¬ bezug-Käufers hinsichtlich der anzusetzenden Matratzenhöhe, die bei einer leicht ballig ausgeformten Matratze schwer zu bestimmen ist und auch das Be¬ dürfnis, einen solchen Matratzenbezug notfalls für eine andere Matratze ver- wenden zu können, lassen eine Anpaßbarkeit des Matratzenbezugs 1 an unterschiedliche Matratzenhöhen vorteilhaft erscheinen.Two further zipper sides (zipper halves 7 and 8) are additionally attached to the lower part 3 and run parallel to the zipper 6, so that one side of the zipper 6, which is fastened to the upper part 2, can be connected to the zipper sides 7 or 8, if a mattress with a lower mattress height is to be covered. Inaccuracies or changes in the mattress height, even more uncertainties of a mattress cover buyer with regard to the mattress height to be applied, which is difficult to determine with a slightly crowned mattress and also the need to use such a mattress cover for another mattress if necessary - To be able to make adaptability of the mattress cover 1 to different mattress heights appear advantageous.
Das Oberteil 2 umfaßt insbesondere eine Oberseite 9 des Matratzenbezugs 1 und daneben einen angrenzenden Randstreifen in den Randseiten 4,5 und den nicht dargestellten Randseiten des Matratzenbezugs 1 , wobei sich letzteres insbesondere aus dem Bedürfnis ergibt, eine glatte, ungestörte Oberseite zu erhalten und Verbindungsmittel wie den Reißverschluß in die Randseiten zu verlagern. Dieses öffnet aber auch die vorerwähnte Möglichkeit einer Höhen¬ anpassung durch verschiedene Reißverschlußseiten 6,7,8.The upper part 2 comprises in particular an upper side 9 of the mattress cover 1 and next to it an adjacent edge strip in the edge pages 4, 5 and the non-illustrated edge sides of the mattress cover 1, the latter resulting in particular from the need to obtain a smooth, undisturbed upper side and connecting means such as to move the zipper to the edges. However, this also opens up the above-mentioned possibility of height adjustment by means of different zipper sides 6, 7, 8.
Das Oberteil 2 besteht aus einem Baumwollmaterial, das sich hinsichtlich seiner Feuchtigkeitsabsorption (Schweißabsorption) und seiner Dampfdurch¬ lässigkeit im Bettwäschebereich bewährt hat. Es versteht sich, daß grundsätz¬ lich auch eine andere entsprechend körperfreundliche Faser oder ein Misch¬ gewebe eingesetzt werden kann. Mit Vorteil wird ein Inlett-Gewebe wegen sei¬ ner erprobten Fertigungsmöglichkeiten, Festigkeit und Haltbarkeit, etwa in einer Garnfeinheit von Nm 70/1 (70 km/kg) verwandt. Damit ist eine Oberfläche mit guten Gebrauchseigenschaften gewährleistet.The upper part 2 consists of a cotton material that has proven itself in terms of its moisture absorption (sweat absorption) and its vapor permeability in the bedding area. It goes without saying that another correspondingly body-friendly fiber or a mixed fabric can also be used in principle. An inlay fabric is advantageously used because of its proven manufacturing possibilities, strength and durability, for example in a yarn count of Nm 70/1 (70 km / kg). This guarantees a surface with good usage properties.
Die funktionellen Eigenschaften des Oberteils 2 werden allerdings sehr we¬ sentlich durch eine dem Oberseitenmateriai unterlegte Schicht aus einem weniger als 50 μm (z.B. 30 μm) dicken Polyurethan bestimmt, die so bemessen und eingestellt ist, daß sie zwar dampfdurchlässig, jedoch eine verläßliche Barriere gegen Allergene, insbesondere gegen Milbenkot mit einer Größe von etwa 1 μm, darstellt. Die Wasserdampfdurchlässigkeit nach DIN 53122/Klima B beträgt ca. 1300 g/m2 d. Hierzu ist das Oberseiteπmaterial des Oberteils 2 gekrumpft und auf der der Matratze zugewandten Rückseite glättend vorbear¬ beitet, etwa geschliffen, um die Barriereschicht als Beschichtung aufzunehmen. Oberflächenmaterial und Beschichtung sind dann zwischenraumfrei zu einer Dicke von etwa 220 μm miteinander verbunden, wobei das Oberflächenmaterial auch als Schutz und Träger für die Beschichtung dient.The functional properties of the upper part 2 are, however, determined very significantly by a layer of a less than 50 μm (for example 30 μm) thick polyurethane underlying the top material, which is dimensioned and adjusted in such a way that it is vapor-permeable but a reliable barrier against Allergens, especially against mite droppings with a size of about 1 micron. The water vapor permeability according to DIN 53122 / Klima B is approximately 1300 g / m 2 d. For this purpose, the top material of the upper part 2 has been shrunk and smoothed, for example ground, on the rear side facing the mattress, in order to receive the barrier layer as a coating. The surface material and coating are then connected to one another without a gap to a thickness of approximately 220 μm, the surface material also serving as a protection and support for the coating.
Das Unterteil 3 besteht aus einem milbendicht ausgelegten Unterseitenmaterial und bildet seinerseits eine Unterseite 10 des Matratzenbezugs (vergl. Fig. 2) und die vom Oberteil 2 nicht erfaßten Bereiche der Randseiten, u.a. Randsei¬ ten 4 und 5. Das Unterteil 3 ist hier gleichfalls aus einem Inlettgewebe gefertigt, das schon aufgrund seiner dichten Webart mit ca. 85% relativer Dichte Milben zurückhält. Ein solches Gewebe, das typischerweise in Köperbindung ausge¬ führt ist, mit einer Feinheit des Garns von Nm 40/1, d.h. mit einem Garn, das bei einem Kilo Garngewicht eine Fadenlänge von 40 km liefert, ist einerseits dicht und fest, andererseits aber auch in bekannter Weise luft- und dampf¬ durchlässig.The lower part 3 consists of a mite-proof underside material and in turn forms an underside 10 of the mattress cover (see FIG. 2) and the areas of the edge sides not covered by the upper part 2, among other things. Randsei¬ ten 4 and 5. The lower part 3 is also made of a ticking fabric that retains mites due to its dense weave with about 85% relative density. Such a fabric, which is typically made in twill weave, with a fineness of the yarn of Nm 40/1, i.e. with a yarn that provides a thread length of 40 km with a kilo of yarn weight is on the one hand tight and firm, but on the other hand also permeable to air and steam in a known manner.
Wie aus Fig. 2 ersichtlich, weist die Unterseite zu allen vier Ecken hin Raffun¬ gen 11 auf, die durch diagonal ausgerichtete elastische Bänder 12, innenseitig (matratzenseitig) in den Matratzenbezug eingenäht, erzeugt werden. Diese Raffungen haben zum einen die Aufgabe, die Matratze ihrerseits mit deren Unterlage gegen Verschiebungen zu sichern, insbesondere auch beim Abzie¬ hen des Oberteils, eine feste Lage der Matratze und des Matratzenbezug-Un¬ terteils zu erhalten. Weiterhin aber schaffen diese elastisch auseinanderzieh- baren Raffungen 11 einen verbesserten Sitz der Matratze in den Eckbereichen, zumal Matratzen regelmäßig in den Ecken mehr oder weniger abgerundet sind.As can be seen from FIG. 2, the underside has ruffles 11 towards all four corners, which are produced by diagonally aligned elastic bands 12 sewn on the inside (mattress side) into the mattress cover. On the one hand, these gathers have the task of securing the mattress with its base against displacement, in particular also when the upper part is removed, to maintain a fixed position of the mattress and the lower part of the mattress cover. But they still create elastic pull apart cash ruffles 11 an improved fit of the mattress in the corner areas, especially since mattresses are regularly more or less rounded in the corners.
Aus Fig. 3 ist ein Schnitt durch den Matratzenbezug 1 , etwa im Bereich der Randseite 5, schematisiert wiedergegeben. Das Oberteil 2 mit der Oberseite 9 schließt mit einer Reißverschlußseite 13 ab, wobei das Oberseitenmaterial des Oberteils 2 zur Bildung eines sauberen Randabschlusses innenseitig umgelegt und damit durch eine Naht 14 mit der Reißverschlußseite zusammengenäht ist. Das Unterteil 3 weist drei zu der Reißverschlußseite 13 des Oberteils 2 pas¬ sende Reißverschlußseiten 15,16,17 auf, die gleichfalls durch eine in gebro¬ chenen Linien dargestellte Naht 18,19 bzw. 20 eingenäht sind. Wie insbeson¬ dere an den Reißverschlußseiten 16 und 17 erkennbar ist, sind diese in eine S- Längsfalte des Unterseitenmaterials eingenäht, so daß das Unterseitenmaterial durchgängig erhalten bleibt und die Reißverschlußseiten nach innen hin umschließt. Damit ist auch eine Milbensicherheit der Unterseite auch für den Fall gewährleistet, daß die Reißverschlußseiten insbesondere im Nahtbereich im Gebrauch Öffnungen darbieten. Auch im Bereich der Reißverschlußseite 15, die im vorliegenden Fall (in durchgehender Linie) lediglich an einen rückge¬ falteten Rand des Unterteils 3 - ähnlich wie die Reißverschlußseite 13 - am Oberteil angenäht sein soll, kann grundsätzlich auch ein nach oben überste¬ hender und innenseitig an die Reißverschlußseite 15 angenähter Rand vorge¬ sehen werden, um eine weitergehende Milbenbarriere zu schaffen.A section through the mattress cover 1, for example in the region of the edge side 5, is shown schematically in FIG. 3. The upper part 2 with the upper side 9 ends with a zipper side 13, the upper side material of the upper part 2 being folded over on the inside to form a clean edge finish and thus sewn together with the zipper side by a seam 14. The lower part 3 has three zipper sides 15, 16, 17 which match the zipper side 13 of the upper part 2 and which are likewise sewn in by means of a seam 18, 19 or 20 shown in broken lines. As can be seen in particular on the zipper sides 16 and 17, these are sewn into an S longitudinal fold of the underside material, so that the underside material is consistently preserved and encloses the zipper sides towards the inside. This also ensures that the underside is mite-proof even in the event that the zipper sides, particularly in the seam area, present openings during use. Also in the area of the zipper side 15, which in the present case (in a continuous line) is only to be sewn onto a folded-back edge of the lower part 3 - similar to the zipper side 13 - on the upper part, there can in principle also be an upwardly projecting inside edge sewn to the zipper side 15 are provided in order to create a further-reaching mite barrier.
In Fig. 4 ist, gleichfalls im Schnitt wie in Fig. 3, ein abgewandelter Matratzen¬ bezug dargestellt, bei dem allerdings das Unterteil 3 dem in Fig. 3 dargestellten Unterteil entspricht und im ganzen wie auch im einzelnen mit den gleichen Be¬ zugszeichen versehen ist.4, likewise in section as in FIG. 3, shows a modified mattress cover, in which, however, the lower part 3 corresponds to that shown in FIG. 3 The lower part corresponds and is provided with the same reference numerals as a whole and in detail.
Ein Oberteil 2' mit einer innenliegenden Reißverschlußseite 13' weist einen randseitig soweit nach unten erstreckten Überhang 21 auf, daß dieser die Reißverschlußseiten des Unterteils 3 abdeckt. Dieses Abdecken der Reißver¬ schlußseiten ist auch für das Erscheinungsbild und die Benutzung von Vorteil, da die Reißverschlußseiten nicht optisch zu Tage treten und die "kratzigen" Metallteile bei der Benutzung ummanteln.An upper part 2 'with an inner zipper side 13' has an overhang 21 which extends downwards on the edge side to such an extent that it covers the zipper sides of the lower part 3. This covering of the zipper sides is also advantageous for the appearance and use, since the zipper sides do not appear visually and coat the "scratchy" metal parts when in use.
Insbesondere aber geht es darum, daß auch an der Seite ein guter Schutz gegen das Eindringen von Milben in die Matratze, gegen das Eindringen von Hautpartikeln in die Matratze und gegen einen Austritt von allergenen Partikeln erreicht wird.In particular, however, it is important that good protection is also achieved on the side against the penetration of mites into the mattress, against the penetration of skin particles into the mattress and against the escape of allergenic particles.
In dieser Hinsicht kann der Überhang 21 vorteilhaft aus dem gleichen allergen¬ dichten Material wie das Material an der Oberseite 9 ausgebildet sein, indem es beispielsweise dessen Fortsetzung bildet. Im Seitenbereich kann es zusätzlich - insbesondere innenseitig - verstärkt, gegen Reibbelastungen an den Reißver¬ schlüssen kaschiert oder gepolstert sein.In this regard, the overhang 21 can advantageously be formed from the same allergen-tight material as the material on the top 9, for example by forming its continuation. In the side area, it can additionally be reinforced, in particular on the inside, laminated or padded against frictional loads on the zippers.
Zu einem vorteilhaften eng anliegenden Abschluß kann ein Hohlsaum 22 für ein Band, insbesondere ein elastisches Band, zu einem festen Anziehen gegen das Unterteil 3 und die Matratze vorgesehen sein. Bei den vorstehenden Ausführungsbeispielen ist vorgesehen worden, daß das Oberteil eine Reißverschlußseite und das Unterteil drei Reißverschlußseiten trägt. Es versteht sich, daß sowohl Oberteil wie auch Unterteil 2 oder mehr Reißverschlußseiten - auch unterschiedlicher Abstände voneinander - auf¬ weisen können, um entsprechende Kombinationsmöglichkeiten zur Anpassung an eine Matratzengröße zu schaffen. For an advantageous close fitting, a hemstitch 22 for a band, in particular an elastic band, can be provided for firm tightening against the lower part 3 and the mattress. In the above exemplary embodiments, it has been provided that the upper part carries one zip side and the lower part carries three zip sides. It goes without saying that both the upper part and the lower part can have two or more zipper sides - even at different distances from one another - in order to create suitable combination options for adapting to a mattress size.
