Abstract

The life-saving flying suit, especially for pilots who eject over water, is composed of a waterproof woven fabric (1) containing an air-permeable zone at the chest, with a ventilation channel (3) of an airtight material. The channel runs through the interior of the garment to give an air exchange between the air-permeable zone and the ambient atmosphere (7). The end (4) of the channel at the air-permeable zone is fastened to the inner side (11) of the fabric by a bonding seam (10), which is impermeable to water and air. The channel is filled with an air-permeable distance piece (12), to prevent the inner channel walls(13) sticking together.

Description

Die Erfindung betrifft einen Schutzanzug nach dem Oberbegriff von Anspruch 1.The invention relates to a protective suit according to the preamble of claim 1.

Bei den bekannten Seenotrettungsanzügen für Piloten tritt bei einem Notausstieg aus dem im Flug befindlichen Flugzeug das Problem auf, dass bei einer Öffnung des Cockpits aufgrund des raschen Druckabfalls auf den tatsächlichen Höhendruck der Seenotrettungsanzug zunächst aufgebläht und anschließend wieder zusammengepresst wird. Zu einem Aufblähen des Schutzanzuges kann es ferner bei einer Dekompression im Cockpit des Flugzeuges kommen, welche beispielsweise in der Aufstiegsphase des Flugzeugs oder bei einem Ausfall der Druckregelanlage kommen kann. Das starke Aufblähen des Schutzanzuges kann dazu führen, dass der Pilot bewegungsunfähig wird, weil die Ärmel und Beine des Schutzanzuges steif werden. Der Pilot ist deshalb möglicherweise nicht mehr in der Lage, das Flugzeug zu steuern und insbesondere in einen Sturzflug zu bringen. Weiterhin treten bei den bekannten Seenotrettungsanzügen ähnliche Probleme bei einem Sturzflug auf, denn schrumpft der Schutzanzug zusammen und engt die Bewegungsfreiheit des Piloten beträchtlich ein. Der Grund für das Aufblähen bzw. Zusammenschrumpfen des Anzuges ist darin zu sehen, dass das Gewebe des Anzugs sowohl wasser- als auch luftdicht ausgebildet ist. Dies ist erforderlich, um dem Piloten, insbesondere bei einem Ausstieg über Wasser, ausreichenden Schutz vor Nässe und Kälte zu geben. Weiterhin ist erforderlich, dass der Rettungsanzug den Piloten vor Feuer schützen kann, weshalb die Anzüge gewöhnlich aus einem schwer entflammbaren Gewebe gefertigt sind.In the known sea rescue suits for pilots in the event of an emergency exit from the Flight aircraft encountered the problem of opening the cockpit due to the rapid drop in pressure to the actual altitude pressure of the sea rescue suit initially is inflated and then compressed again. To inflate the Protective suit can also occur during decompression in the cockpit of the aircraft, which, for example, in the ascent phase of the aircraft or in the event of a failure of the Pressure control system can come. The swelling of the protective suit can cause that the pilot becomes immobile because the sleeves and legs of the protective suit are stiff become. The pilot may therefore no longer be able to control the aircraft and especially to make a dive. Furthermore occur in the known Sea rescue suits face similar problems when diving, because the shrinks Protective suit together and considerably limits the pilot's freedom of movement. The The reason for the bloating or shrinking of the suit can be seen in the fact that the fabric of the suit is both waterproof and airtight. This is necessary to ensure that the pilot is adequately supported, especially when getting out of the water To give protection from wetness and cold. It is also necessary that the rescue suit Can protect pilots from fire, which is why the suits are usually heavy flammable fabrics are made.

Aufgabe der vorliegenden Erfindung ist es, einen Schutzanzug für Piloten bereit zu stellen, bei dem ein unerwünschtes Aufblähen bzw. Schrumpfen des Anzuges bei einer Druckänderung vermieden wird.The object of the present invention is to provide a protective suit for pilots, in which an undesirable bloating or shrinking of the suit in a Change in pressure is avoided.

Gelöst wird diese Aufgabe mit einem Schutzanzug mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsbeispiele des Schutzanzugs sind den Unteransprüchen zu entnehmen. This object is achieved with a protective suit with the features of claim 1. Advantageous embodiments of the protective suit can be found in the subclaims remove.

Gemäß der Erfindung ist der Schutzanzug aus einem wasserdichten Gewebe gebildet, wobei in das Gewebe eine luftdurchlässige Zone eingearbeitet ist und ein aus einem luftdichten Material gebildeter Entlüftungskanal vorgesehen ist, welcher im Inneren des Schutzanzugs verlaufend an einem Ende mit der luftdurchlässigen Zone in Verbindung steht und dessen anderes, als Mündung ausgebildetes Ende in das Innere des Schutzanzugs mündet um einen Luftaustausch zwischen dem Inneren des Schutzanzugs und der Umgebung zu ermöglichen. Bei einer Druckänderung in der Umgebung, beispielsweise im Cockpit des Flugzeugs, ist damit ein Druckausgleich zwischen dem Inneren des Schutzanzugs und der Umgebung möglich, wodurch ein unerwünschtes Aufblähen des Anzugs vermieden wird.According to the invention, the protective suit is formed from a waterproof fabric, wherein an air-permeable zone is worked into the fabric and an air-tight zone Material formed ventilation channel is provided, which is inside the protective suit is connected at one end to the air-permeable zone and its another end, designed as a mouth, opens into the inside of the protective suit around one To allow air exchange between the inside of the protective suit and the environment. When there is a change in pressure in the environment, for example in the cockpit of the aircraft thus a pressure equalization between the inside of the protective suit and the environment possible, thereby avoiding an undesirable inflation of the suit.

Damit bei einer Seenotrettung das Eindringen von Wasser durch die luftdurchlässige Zone in das Innere des Schutzanzugs verhindert wird, ist die Mündung des Entlüftungskanals bevorzugt so angeordnet, dass sie bei angelegtem Schutzanzug oberhalb des Brustbereichs liegt, bevorzugt im Bereich der Schulter oder des Kragens. Falls Wasser durch die luftdurchlässige Zone in das Innere des Schutzanzugs eindringen sollte, kann dieses Wasser dennoch nicht in das Anzuginnere laufen, solange die Mündung des Entlüftungskanals oberhalb der Wasseroberfläche liegt. Einen zusätzlichen Schutz gegen das Einlaufen von Wasser in das Anzuginnere bietet ein wasserabsorbierendes Medium, welches bei einem bevorzugten Ausführungsbeispiel des Schutzanzugs im Lüftungskanal, insbesondere in der Nähe der luftdurchlässigen Zone, eingebracht ist. Bei Eindringen von Wasser durch die luftdurchlässige Zone saugt dieses wasserabsorbierende Medium das eindringende Wasser auf und verhindert auf diese Weise ein Einlaufen von Wasser in das Anzuginnere. Erst wenn das wasserabsorbierende Medium gesättigt ist, besteht die Gefahr des Eindringens von Wasser in das Anzuginnere. Bevorzugt handelt es sich bei dem wasserabsorbierenden Medium um ein Polymer, welches bei Kontakt mit Wasser ein Hydrogel bildet.So that in the event of a sea rescue, water can penetrate through the air-permeable zone in the inside of the protective suit is prevented, is the mouth of the ventilation duct preferably arranged so that they are above the chest area when the protective suit is on lies, preferably in the area of the shoulder or the collar. If water through the air permeable zone should penetrate into the inside of the protective suit, this water can nevertheless, do not run into the inside of the suit as long as the mouth of the ventilation duct lies above the water surface. Additional protection against shrinking Water in the inside of the suit offers a water-absorbing medium, which in one preferred embodiment of the protective suit in the ventilation duct, in particular in the Near the air-permeable zone. If water penetrates through the air-permeable zone, this water-absorbing medium absorbs the penetrating water and prevents water from entering the inside of the suit. Only when that water-absorbing medium is saturated, there is a risk of water ingress the inside of the suit. The water-absorbing medium is preferably a Polymer that forms a hydrogel on contact with water.

In einem bevorzugten Ausführungsbeispiel des Schutzanzugs ist das mit der luftdurchlässigen Zone in Verbindung stehende Ende des Entlüftungskanals durch eine wasser- und luftdichte Verbindung, insbesondere eine mit Polyurethanschweißbändern abgedichtete Naht, an der Innenseite des Gewebes befestigt.In a preferred embodiment of the protective suit, this is with the air-permeable Zone-connecting end of the ventilation duct through a water and airtight Connection, in particular a seam sealed with polyurethane sweatbands, on the Attached to the inside of the fabric.

Um ein Aneinanderhaften der Innenwände des Entlüftungskanals zu verhindern, ist in einem bevorzugten Ausführungsbeispiel des Schutzanzugs ein luftdurchlässiges Distanzmaterial in den Entlüftungskanal eingeschoben. Die Innenwände des Entlüftungskanals sind bevorzugt aus polyurethanbeschichtetem Polyamid gebildet. Die luftdurchlässige Zone im wasserdichten Gewebe des Schutzanzugs ist beispielsweise von einer mit einem Reißverschluß verschließbaren Öffnung gebildet. Auch bei geschlossenem Reißverschluß ist ein Luftdurchlass durch den Reißverschluß gewährleistet. Bei dem Gewebe, aus dem der Schutzanzug gefertigt ist, handelt es sich bevorzugt um ein schwer entflammbares Laminat, welches wasserdampfdurchlässig, jedoch luftdicht ist.To prevent the inner walls of the ventilation duct from sticking together, is in one preferred embodiment of the protective suit in an air-permeable spacer material inserted the ventilation duct. The inner walls of the ventilation duct are preferred made of polyurethane-coated polyamide. The air permeable zone in the waterproof The fabric of the protective suit is, for example, one with a zipper closable opening formed. Even when the zipper is closed is a Air passage guaranteed by the zipper. In the tissue from which the Protective suit is made, it is preferably a flame-retardant laminate, which is permeable to water vapor, but is airtight.

Nachfolgend wird ein Ausführungsbeispiel des Schutzanzugs unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert. Die Zeichnungen zeigen:

Die Figur 1 zeigt einen einteiligen Pilotenanzug aus einem wasserdichten Gewebe 1. Bei dem Gewebe 1 handelt es sich um ein schwer entflammbares, dreilagiges Laminat mit einem Flächengewicht von etwa 245 g/m2. Das Gewebe 1 erfüllt insbesondere Index 3 bei der Prüfung und Beurteilung der Schwerentflammbarkeit nach EN 532/533. Um einen möglichst guten Tragekomfort zu gewährleisten ist das Gewebe 1 wasserdampfdurchlässig.1 shows a one-piece pilot suit made of a waterproof fabric 1. The fabric 1 is a flame-retardant, three-layer laminate with a weight per unit area of approximately 245 g / m 2 . The fabric 1 fulfills index 3 in particular when testing and assessing the flame resistance according to EN 532/533. In order to ensure the best possible comfort, the fabric 1 is permeable to water vapor.

Im Brustbereich des Anzugs ist in das wasserdichte und luftundurchlässige Gewebe 1 eine luftdurchlässige Zone 2 eingearbeitet. Diese luftdurchlässige Zone 2 wird in dem in Figur 1 dargestellten Ausführungsbeispiel von einem Reißverschluß 15 gebildet. Bei diesem Reißverschluß handelt es sich um einen herkömmlichen Reißverschluß mit zwei Kuppelgliederreihen 16, 17, welche bei geschlossenem Reißverschluß miteinander im Eingriff stehen (Figur 2). Die Kuppelglieder der beiden Kuppelgliederreihen 16, 17 sind jeweils an den äußeren Enden von Stoffbändern 18, 19 befestigt. Der Reißverschluß 15 ist somit luftdurchlässig ausgebildet. In the chest area of the suit is in the waterproof and airtight fabric 1 Air-permeable zone 2 incorporated. This air-permeable zone 2 is in the in FIG illustrated embodiment formed by a zipper 15. With this Zipper is a conventional zipper with two Coupling element rows 16, 17, which engage with one another when the zipper is closed stand (Figure 2). The coupling elements of the two coupling element rows 16, 17 are each on attached to the outer ends of fabric ribbons 18, 19. The zipper 15 is thus breathable.

Wie aus Figur 2 ersichtlich sind die den Kuppelgliederreihen 16, 17 gegenüberliegenden Kanten der Stoffbänder 18 und 19 auf der Außenseite des Gewebes 1 angenäht und Überbrücken eine Öffnung 24 im Gewebe 1. An die beiden Stoffbänder 18, 19 des Reißverschlusses 15 schließen sich auf der Außenseite des Anzugs zwei Besatzstreifen 20, 21 aus textilem Gewebe an. Diese Besatzstreifen 20, 21 und die Bänder 18, 19 des Reißverschlusses 15 sind durch abgedichtete Nähte 10 auf der Außenseite des Gewebes 1 angenäht. Die Nähte 10 sind durch Polyurethan-Schweißbänder abgedichtet.As can be seen from FIG. 2, the rows 16, 17 of the coupling elements are opposite Edges of the fabric strips 18 and 19 sewn on the outside of the fabric 1 and Bridging an opening 24 in the tissue 1. To the two fabric tapes 18, 19 of the Zipper 15 closes two trim strips 20, 21 on the outside of the suit made of textile fabric. These trim strips 20, 21 and the tapes 18, 19 of the Zippers 15 are by sealed seams 10 on the outside of the fabric 1st sewn. The seams 10 are sealed by polyurethane sweatbands.

Wie aus Figur 2 ersichtlich, schließt sich im Inneren 6 des Schutzanzugs unterhalb der Öffnung 24 im Gewebe 1 ein von einer Wandung 22 umschlossener Raum 23 an. Die Wandung 22 ist aus einem luft- und wasserdichten Material, beispielsweise Kunststoff, insbesondere polyurethanbeschichtetes Polyamid, gebildet. Die Wandung 22 ist an der Innenseite 11 des Gewebes 1 über abgedichtete Nähte 10 befestigt. Die Wandung 22 und die Innenseite 11 des Gewebes 1 umschließen damit einen Hohlraum 23, welcher bis auf die durch den Reißverschluß 15 gebildete luftdurchlässige Zone 2 bezüglich der Umgebung 7 luft- und wasserdicht abgeschlossen ist.As can be seen from FIG. 2, the inside of the protective suit closes below the Opening 24 in tissue 1 opens into a space 23 enclosed by a wall 22. The Wall 22 is made of an airtight and watertight material, for example plastic, in particular polyurethane-coated polyamide. The wall 22 is on the Inner side 11 of the fabric 1 fastened via sealed seams 10. The wall 22 and the The inside 11 of the fabric 1 thus enclose a cavity 23 which, apart from the Air-permeable zone 2 formed by the zipper 15 with respect to the environment 7 airtight and watertight.

Der sich in Figur 2 unterhalb der Öffnung 24 befindliche Raum 23 geht in einen Entlüftungskanal 3 über, welcher sich vom Brustbereich des Anzugs bis etwa zur Schulter 8 beziehungsweise zum Kragen im Inneren des Schutzanzuges erstreckt (Figur 1). Der Entlüftungskanal 3 ist rohrförmig ausgebildet, wobei die Rohrwandungen aus demselben Material wie die Wandung 22 des Hohlraums 23 gebildet sind und ineinander übergehen. Das sich im Bereich der Schulter 8 beziehungsweise des Kragens 9 befindliche Ende des Entlüftungskanals 3 ist als Mündung 5 ausgebildet, d. h. dieses Ende des Entlüftungskanals 3 mündet in das Innere des Schutzanzugs. Das andere Ende 4 des Entlüftungskanals 3 liegt im Bereich des Raumes 23 und steht mit der luftdurchlässigen Zone 2, also insbesondere mit der Öffnung 24, in Verbindung. Auf diese Weise ist ein Luftaustausch zwischen der Umgebung 7 und dem Inneren 6 des Schutzanzugs über die luftdurchlässige Zone 2 und durch den Entlüftungskanal 3 bis zu dessen Mündung 5 gewährleistet.The space 23 located in FIG. 2 below the opening 24 merges into one Ventilation channel 3, which extends from the chest area of the suit to approximately the shoulder 8 or extends to the collar inside the protective suit (Figure 1). The Vent channel 3 is tubular, the tube walls made of the same Material such as the wall 22 of the cavity 23 are formed and merge. The located in the shoulder 8 or collar 9 end of the Vent channel 3 is designed as a mouth 5, d. H. this end of the ventilation duct 3 opens into the inside of the protective suit. The other end 4 of the ventilation duct 3 is in the Area of the room 23 and stands with the air-permeable zone 2, in particular with the Opening 24, in communication. In this way there is an exchange of air between the surroundings 7 and the interior 6 of the protective suit over the air-permeable zone 2 and through the Vent channel 3 guaranteed up to its mouth 5.

Um zu verhindern, dass die Innenwände 13 des Entlüftungskanals 3 aneinander haften ist in den Entlüftungskanal 3 ein luftdurchlässiges Distanzmaterial 12 eingebracht. Bei diesem Distanzmaterial kann es sich beispielsweise um einen aufgeschäumten Kunststoff oder ein Vlies handeln. In order to prevent the inner walls 13 of the ventilation duct 3 from sticking to one another in FIG an air-permeable spacer material 12 is introduced into the ventilation duct 3. With this Spacer material can be, for example, a foamed plastic or a Trade fleece.

Im Bereich des Raumes 23, insbesondere nahe der luftdurchlässige Zone 2, ist in den Entlüftungskanal 3 ein wasserabsorbierendes Medium 14 eingebracht. Bei diesem Medium kann es sich beispielsweise um ein Polymer handeln, welches bei Kontakt mit Wasser ein Hydrogel bildet. Dieses wasserabsorbierende Medium wirkt bei Wassereintritt durch die luftdurchlässige Zone 2, also insbesondere durch den wasserdurchlässigen Reißverschluß 15 und die Öffnung 24, wie ein Schwamm und saugt das eintretende Wasser auf. Dadurch wird vermieden, dass bei Wassereintritt durch die luftdurchlässige Zone 2 das eingetretene Wasser durch den Entlüftungskanal 3 in das Innere 6 des Anzugs fließen kann. Erst wenn das wasserabsorbierende Medium mit Feuchtigkeit gesättigt ist, kann das eingetretene Wasser in den oberen Bereich des Entlüftungskanals 3 und bis zur Mündung 5 gelangen. Bei Verwendung von superabsorbierenden Medien 14 kann der Pilot daher bis zu mehreren Stunden im Wasser sein, ohne dass Wasser durch den Entlüftungskanal 3 in das Anzuginnere 6 eindringen kann.In the area of the room 23, in particular near the air-permeable zone 2, in the Vent channel 3 introduced a water-absorbing medium 14. With this medium it can be, for example, a polymer which is in contact with water Hydrogel forms. This water-absorbing medium acts through the water Air-permeable zone 2, in particular through the water-permeable zipper 15 and the opening 24, like a sponge, and absorbs the entering water. This will Avoiding the water entering through water-permeable zone 2 can flow into the interior 6 of the suit through the ventilation duct 3. Only when that water-absorbing medium is saturated with moisture, the water can enter reach the upper area of the ventilation duct 3 and up to the mouth 5. at The pilot can therefore use up to several superabsorbent media 14 Be hours in the water without water through the ventilation channel 3 into the inside of the suit 6 can penetrate.

Die Figur 3 zeigt ein bevorzugtes Ausführungsbeispiels des Schutzanzugs. Gegenüber dem in Figur 2 dargestellten Ausführungsbeispiel unterscheidet sich dieses durch eine zusätzliche Abdeckfolie 25, welche auf dem wasserabsorbierenden Medium 14 im Bereich unterhalb der Öffnung 24 aufgebracht ist. Die Abdeckfolie 25 ist wasser- und luftundurchlässig und beispielsweise aus einer Kunststofffolie gebildet. In ihren Randbereichen ragt sie über die Ränder der Öffnung 24 hinaus uns sie ist an diesen Randbereichen mit dem wasserabsorbierenden Medium beispielsweise durch Nähte oder durch Verklebungsstreifen befestigt. Sollte durch Wassereintritt das wasserabsorbierende Medium 14 in Sättigung gelangt sein, quillt das wasserabsorbierende Medium 14 auf und drückt dadurch die Abdeckfolie 25 in den Bereich der Öffnung 24 und gegen den Reißverschluss 15. Dadurch wird weiteres Eindringen von Wasser durch den Reißverschluss 15 verhindert.Figure 3 shows a preferred embodiment of the protective suit. Opposite the in Figure 2 illustrated embodiment differs this by an additional Cover film 25, which on the water-absorbing medium 14 in the area below the Opening 24 is applied. The cover sheet 25 is impermeable to water and air for example formed from a plastic film. In its edge areas it protrudes above the Edges of the opening 24 and it is at these edge areas with the water-absorbing medium, for example through seams or through adhesive strips attached. Should the water-absorbing medium 14 become saturated by the entry of water reached, the water-absorbing medium 14 swells and thereby presses the Cover 25 in the area of the opening 24 and against the zipper 15. This further penetration of water is prevented by the zipper 15.
