Matratzen, die die luftfahrtrechtlichen Anforderungen erfüllen, bieten in der Regel einen geringen Liegekomfort.The invention relates to a mattress for aircraft. Onboard VIP aircraft, business jets and government aircraft, and occasionally first-class commercial aircraft use beds with a flat sleeping surface. The mattress used for such beds requires aviation law approval and must be tested for flammability, in particular by a method described in more detail below. Mattresses that meet the requirements of aviation law generally offer low lying comfort.

Der Erfindung liegt daher die Aufgabe zugrunde, eine für Luftfahrzeuge geeignete Matratze zu schaffen, die einen höheren Liegekomfort aufweist.The invention is therefore an object of the invention to provide a mattress suitable for aircraft, which has a higher comfort.

  1. a) der Schaumstoffkern weist auf der der Liegefläche zugewandten Seite eine großflächige Ausnehmung auf, die wenigstens 70%, vorzugsweise wenigstens 80%, weiter vorzugsweise wenigstens 90% der Liegefläche einnimmt,
  2. b) die Ausnehmung ist in den Randbereichen der Liegefläche von einem Schaumstoffsteg umgeben,
  3. c) in die Ausnehmung ist eine Liegeunterlage aus einem Abstandstextil eingelegt,
  4. d) die Fasern des Abstandstextils sind schwer entflammbar.
The mattress for aircraft according to the invention has a lying surface and a flame retardant foam core. It is characterized by the following features:
  1. a) the foam core has on the side facing the lying surface on a large-scale recess occupies at least 70%, preferably at least 80%, more preferably at least 90% of the bed surface,
  2. b) the recess is surrounded in the edge regions of the lying surface by a foam web,
  3. c) in the recess a couch pad is inserted from a spacer textile,
  4. d) the fibers of the spacer textile are flame retardant.

Zunächst seien einige im Rahmen der Erfindung verwendete Begriffe erläutert.First, some terms used in the invention are explained.

Der Schaumstoff kern der erfindungsgemäßen Matratze ist schwer entflammbar. Diese Anforderung ist immer dann erfüllt, wenn die fertige Matratze insgesamt die luftfahrtrechtlichen Anforderungen (Näheres siehe unten) erfüllt. Die Liegefläche der erfindungsgemäßen Matratze weist eine Größe auf, die für durchschnittliche Personen ein bequemes Schlafen ermöglicht. In der Regel ist sie mindestens 1,80 m, vorzugsweise mindestens 1,90 m, weiter vorzugsweise mindestens 2,00 m lang und bei einem Einzelbett mindestens 60 cm, vorzugsweise mindestens 80 cm, weiter vorzugsweise mindestens 1 m breit. Die Liegefläche kann sich über die noch näher zu beschreibende großflächige Ausnehmung des Schaumstoffkerns und den Randbereich des Schaumstoffkerns mit seinen Schaumstoffstegen erstrecken. Andere Abmessungen der Liegefläche angepasst an die örtlichen Gegebenheiten sind möglich.The foam core of the mattress according to the invention is difficult to ignite. This requirement is always met when the finished mattress meets all aviation requirements (see below for details). The lying surface of the mattress according to the invention has a size that allows comfortable sleep for average people. In general, it is at least 1.80 m, preferably at least 1.90 m, more preferably at least 2.00 m long and in a single bed at least 60 cm, preferably at least 80 cm, more preferably at least 1 m wide. The lying surface can extend over the large-area recess of the foam core, which will be described in more detail below, and the edge region of the foam core with its foam webs. Other dimensions of the lying surface adapted to the local conditions are possible.

Erfindungsgemäß ist vorgesehen, dass der Schaumstoffkern auf der der Liegefläche zugewandten Seite eine großflächige Ausnehmung aufweist, die die in Anspruch 1 definierten Flächenanteile der entsprechenden Matratzenseite einnimmt. Bei der Ausnehmung handelt es sich vorzugsweise um eine ebene Vertiefung, die vorzugsweise der Matratzenform angepasst ist, also insbesondere rechteckig ist, und die in den Randbereichen der Matratze von einem die Ausnehmung horizontal (senkrecht zur Liegefläche) überragenden Schaumstoffsteg umgeben ist. Anders ausgedrückt besitzt der Schaumstoffkern im Bereich der Ausnehmung eine geringere Dicke als in den Randbereichen des Kerns mit den dort angeordneten Stegen.According to the invention, it is provided that the foam core on the side facing the lying surface has a large-area recess, which occupies the area defined in claim 1 surface portions of the corresponding mattress side. The recess is preferably a flat depression, which is preferably adapted to the shape of the mattress, that is to say in particular rectangular, and which is in the edge regions the mattress is surrounded by a recess extending horizontally (perpendicular to the lying surface) superior foam web. In other words, the foam core has a smaller thickness in the region of the recess than in the edge regions of the core with the webs arranged there.

In die Ausnehmung des Schaumstoffkerns ist eine Liegeunterlage aus einem Abstandstextil eingelegt. Die Fasern dieses Abstandstextils sind schwer entflammbar.In the recess of the foam core a mattress base is inserted from a spacer textile. The fibers of this spacer textile are flame retardant.

Abstandstextilien weisen zwei textile Grundflächen (insbesondere gewebte oder gewirkte Flächen) auf, die im wesentlichen parallel mit einem Abstand zueinander verlaufen und zwischen denen sich die Grundflächen verbindende Abstandsfäden erstrecken, die in die Grundflächen entsprechend dem verwendeten textilen Flächenbildungsverfahren eingebunden sind. Die Abstandsfäden können im Warenlängs- oder Warenquerschnitt diagonal verlaufende, sich kreuzende Erstreckungsrichtungen aufweisen; sie können ferner beliebig zur Herstellungsrichtung des Textils diagonal verlaufende, sich kreuzende Abstandsfäden aufweisen oder aber zwischen den Grundflächen annähernd senkrecht zu diesen Grundflächen verlaufen. Solche Abstandstextilien können Last aufnehmen, dauerelastisch und mit dauernden Rücksprungeigenschaften versehen sein. Aufgrund der zwischen den beiden Grundflächen verlaufenden Abstandsschicht weisen sie sehr gute thermophysiologische Eigenschaften auf und können insbesondere die vom Körper abgegebene Wärme und Feuchtigkeit aufnehmen und ableiten. Für die erfindungsgemäße Matratze geeignete Abstandstextilien sind im Stand der Technik bekannt und beispielsweise in DE 100 26 405 A1 , DE 100 13 492 A1 und DE 102 40 462 A1 beschrieben.Spacer fabrics have two textile base surfaces (in particular woven or knitted surfaces) which extend substantially parallel to one another at a distance from each other and between which the base surfaces connecting spacer threads extend, which are integrated into the base surfaces in accordance with the textile surface-forming method used. The spacer threads may have diagonally extending, extending directions of extension in the longitudinal direction of the goods or goods; Furthermore, they can have arbitrarily intersecting spacer threads running diagonally to the direction of production of the textile, or they can extend approximately perpendicular to these base surfaces between the base surfaces. Such spacer textiles can absorb load, be permanently elastic and provided with continuous return properties. Due to the spacer layer extending between the two base surfaces, they have very good thermophysiological properties and in particular can absorb and dissipate the heat and moisture released by the body. For the mattress according to the invention suitable spacer textiles are known in the art and, for example, in DE 100 26 405 A1 . DE 100 13 492 A1 and DE 102 40 462 A1 described.

Im Stand der Technik sind in Luftfahrzeugen immer nur Schaumstoffmatratzen aus schwer entflammbarem Schaumstoff zum Einsatz gekommen. Eine solche Ausführungsform ist beispielsweise aus der EP-A-0 231 968 bekannt. Der Grund dafür liegt darin, dass die Matratzen für die luftfahrtrechtliche Zulassung einem sogenannten Ölbrennertest und einem Bunsenbrennertest überstehen müssen (FAR/EASA §25.853 Flammability of Seat Cushions) Flammfest ausgerüstete Schaumstoffblöcke sind geschlossenzelliger Schaumstoff und ermöglichen keine Feuchtigkeitszirkulation. Die Liegeeigenschaften sind daher ungünstig.In the prior art are in aircraft always only foam mattresses made of flame-retardant foam used. Such an embodiment is for example from the EP-A-0 231 968 known. The reason for this is that the mattresses for aviation approval must withstand a so-called oil burner test and a Bunsen burner test (FAR / EASA §25.853 Flammability of Seat Cushions) Flame-retardant foam blocks are closed-cell foam and do not allow moisture to circulate. The lying properties are therefore unfavorable.

Bei dem genannten Ölbrennertest wird ein Sitzkissen bzw. die Matratze von der Seite her (also parallel zur Liegefläche) einer Kerosinflamme ausgesetzt und darf dabei nur innerhalb bestimmter in der genannten Vorschrift näher beschriebenen Grenzen verbrannt bzw. zerstört werden. Dieser Ölbrennertest ist im Stand der Technik immer nur von entsprechend ausgerüsteten Schaumstoffmatratzen überstanden worden.In the case of the aforementioned oil burner test, a seat cushion or the mattress is exposed from the side (ie parallel to the lying surface) to a kerosene flame and may only be burned or destroyed within certain limits described in more detail in said specification. This oil burner test has always been overcome in the prior art only by suitably equipped foam mattresses.

Die erfindungsgemäß verwendeten Abstandstextilien sind eigentlich völlig ungeeignet, um den Ölbrennertest zu bestehen. Der Grund dafür liegt darin, dass sie zwischen den beiden Textilschichten eine nur relativ locker mit Abstandsfäden gefüllte Abstandsschicht aufweisen, die beim Einwirken einer Flamme von der Seite her wie ein Kaminzug wirkt und die Flamme sowie heiße Brandgase schnell über eine große Fläche verteilt. Überraschenderweise hat sich nun gezeigt, dass trotzdem die Verwendung eines komforterhöhenden Abstandstextils bei einer Luftfahrtmatratze möglich ist, wenn dieses Textil seitlich von den im Patentanspruch näher definierten Schaumstoffstegen umschlossen ist. Der Schaumstoffsteg sorgt dafür, dass beim Ölbrennertest (Flammeinwirkung von der Seite her) die Flamme nicht unmittelbar auf das Abstandstextil einwirkt und insbesondere nicht von der Seite her in den Abstand zwischen den beiden Gewebeflächen oder Gewirkeflächen hineinschlagen kann. Stattdessen blockiert der Schaumstoffsteg die Flamme hinreichend lange, um eine großflächige Ausbreitung der Brandgase und Brandwirkungen durch den Abstandsraum des Abstandstextils zu vermeiden.The spacer textiles used according to the invention are actually completely unsuitable for passing the oil burner test. The reason for this is that between the two textile layers they have a spacing layer which is only loosely filled with spacer threads and acts as a chimney draft from the side when a flame acts and quickly distributes the flame and hot combustion gases over a large area. Surprisingly, it has now been shown that nevertheless the use of a comfort-increasing spacer textile is possible with an aviation mattress if this textile is enclosed laterally by the foam webs defined in greater detail in the patent claim. The foam web ensures that during the oil burner test (flame exposure from the side) the flame does not act directly on the spacer textile and in particular can not strike from the side into the distance between the two fabric surfaces or knitted surfaces. Instead, the foam web blocks the flame sufficiently long, in order to avoid a widespread propagation of the combustion gases and fire effects through the distance space of the spacer fabric.

Der Schaumstoffsteg umschließt die Randbereiche der Liegefläche. Er kann erfindungsgemäß insbesondere eine horizontale Breite (parallel zur Liegefläche) von 2 bis 9 cm aufweisen. Diese Dicke reicht aus, um beim Ölbrennertest die Flamme weitgehend von einem seitlichen Einschlagen in das Abstandstextil abzuhalten. Die Tiefe der Ausnehmung und die Dicke der Unterlage beträgt vorzugsweise 2 bis 6 cm, weiter vorzugsweise etwa 3 cm. Vorzugsweise entspricht die Dicke der Liegeunterlage in etwa der Tiefe der Ausnehmung.The foam web encloses the edge regions of the lying surface. It can according to the invention in particular have a horizontal width (parallel to the lying surface) of 2 to 9 cm. This thickness is sufficient to prevent the flame in the oil burner test largely from a lateral impact into the spacer textile. The depth of the recess and the thickness of the pad is preferably 2 to 6 cm, more preferably about 3 cm. Preferably, the thickness of the mattress base corresponds approximately to the depth of the recess.

Bei dem Abstandstextil handelt es sich bevorzugt um ein Abstandsgewebe oder besonders bevorzugt ein Abstandsgewirke. Bei einem Abstandsgewebe sind die textilen Grundflächen gewebt, bei einem Gewirke dementsprechend gewirkt. Zwischen diesen textilen Grundflächen oder Grundschichten erstrecken sich die oben bereits beschriebenen Fadenscharen, die integral mit den beiden Grundflächen verwoben bzw. verwirkt sind. Es handelt sich bevorzugt um flammfeste Fäden, die flammfeste Materialien wie bspw. Kevlar enthalten. Die Herstellung der Liegeunterlage aus von vornherein flammfesten Fäden (anstelle einer flammfesten Ausrüstung) hat den Vorteil, dass die Atmungsaktivität der Liegeunterlage erhalten bleibt und damit der Liegekomfort erhöht wird.The spacer textile is preferably a spacer fabric or particularly preferably a spacer fabric. In a spacer fabric, the textile base surfaces are woven, knitted in a knitted fabric accordingly. The thread groups already described above, which are woven or forfeited integrally with the two base surfaces, extend between these textile bases or base layers. It is preferably flame-resistant threads containing flame-resistant materials such as Kevlar. The preparation of the mattress from the outset flame-resistant threads (instead of a flame-resistant equipment) has the advantage that the breathability of the mattress is maintained and thus the sleeping comfort is increased.

Wenn in diesem Zusammenhang von flammfest bzw. schwer entflammbar die Rede ist, zielt dies immer auf eine Beschaffenheit bzw. Ausrüstung ab, die die erfindungsgemäße Matratze insgesamt den genannten Ölbrennertest bestehen lässt.If in this context of flameproof or flame retardant is mentioned, this always aims at a condition or equipment that leaves the mattress according to the invention as a whole the said oil burner test.

Die Liegeunterlage ist bevorzugt in die Ausnehmung des Schaumstoffkerns eingelegt und kann so bei Bedarf gereinigt bzw. gewechselt werden. Sie kann antiallergen wirken, da Allergene durch die lockeren Fadenscharen der Abstandsschicht zwischen den beiden Textilgrundflächen sozusagen durchfallen.The mattress base is preferably inserted into the recess of the foam core and can be cleaned as needed or to be changed. It can have an anti-allergenic effect, since allergens fall through the loose flocks of the spacer layer between the two textile base surfaces, so to speak.
