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 case of known emergency rescue suits for pilots, an emergency exit from the aircraft in flight causes the problem that when the cockpit opens, due to the rapid drop in pressure on the actual altitude pressure, the lifeguard suit is first inflated and then compressed again. Inflation of the protective suit can also occur during decompression in the cockpit of the aircraft, which can occur, for example, in the ascent phase of the aircraft or in the event of a failure of the pressure control system. The heavy swelling of the suit can cause the pilot to become immobilized because the sleeves and legs of the suit become stiff. The pilot may therefore no longer be able to control the aircraft and in particular to take a dive. Furthermore, in the known Lifeboat suits occur similar problems in a dive, because shrinks the suit together and narrows the freedom of movement of the pilot considerably. The reason for the swelling or shrinking of the suit is that the fabric of the suit is both waterproof and airtight. This is necessary in order to give the pilot adequate protection against moisture and cold, especially when getting out of the water. Furthermore, it is required that the rescue suit can protect the pilot from fire, which is why the suits are usually made of a flame retardant fabric.

Ein Schutzanzug für Piloten ist aus US 4 633 526 bekannt.A protective suit for pilots is out US 4 633 526 known.

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.Object of the present invention is to provide a protective suit for pilots, in which an undesirable swelling or shrinkage of the suit is avoided in a pressure change.

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 having the features of claim 1. Advantageous embodiments of the protective suit can be found in the dependent claims.

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 of a waterproof fabric, in which an air-permeable zone is incorporated and a venting channel formed of an airtight material is provided, which in the interior of the protective suit is connected at one end to the air-permeable zone and the another, designed as an orifice end opens into the interior of the suit to allow air exchange between the interior of the suit and the environment. In a pressure change in the environment, for example in the cockpit of the aircraft, so that a pressure equalization between the inside of the suit and the environment is possible, whereby an undesirable inflation of the suit is avoided.

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.In order to prevent the ingress of water through the air-permeable zone into the interior of the protective suit during a sea rescue, the mouth of the venting channel is preferably arranged so that it is above the chest area when the protective suit is applied, preferably in the region of the shoulder or the collar. If water should penetrate through the air-permeable zone into the inside of the suit, this water can still not run into the inside of the suit, as long as the mouth of the vent channel is above the water surface. An additional protection against the ingress of water into the inside of the suit provides a water-absorbing medium, which is introduced in a preferred embodiment of the suit in the ventilation duct, in particular in the vicinity of the air-permeable zone. When water penetrates through the air-permeable zone, this water-absorbing medium absorbs the penetrating water and in this way prevents water from entering the interior of the suit. Only when the water-absorbing medium is saturated, there is a risk of water entering the inside of the suit. The water-absorbing medium is preferably a polymer which 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, the end of the venting channel communicating with the air-permeable zone is secured to the inside of the fabric by a water and airtight connection, in particular a seam sealed with polyurethane welding tapes.

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.In order to prevent the inner walls of the ventilation channel from sticking together, in a preferred exemplary embodiment of the protective suit, an air-permeable spacer material is inserted into the ventilation channel. The inner walls of the venting channel are preferred made of polyurethane-coated polyamide. The air-permeable zone in the waterproof fabric of the suit is formed for example by a closable with a zipper opening. Even with the zipper closed, an air passage through the zipper is guaranteed. The fabric from which the protective suit is made is preferably a flame retardant laminate which is permeable to water vapor but 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.The FIG. 1 shows a one-piece pilot suit of a waterproof fabric 1. The fabric 1 is a flame-retardant, three-ply laminate with a basis weight of about 245 g / m 2 . The fabric 1 meets in particular Index 3 in the examination and assessment of flame retardancy according to EN 532/533. To ensure the best possible wearing 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, an air-permeable zone 2 is incorporated into the watertight and air-impermeable fabric 1. This air-permeable zone 2 is in the in FIG. 1 illustrated embodiment of a zipper 15 formed. This zipper is a conventional zipper with two rows of coupling elements 16, 17, which engage with the zipper closed ( FIG. 2 ). The coupling elements of the two rows of coupling elements 16, 17 are respectively attached to the outer ends of cloth bands 18, 19. The zipper 15 is thus designed to be permeable to air.

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.How out FIG. 2 the edges of the cloth bands 18 and 19 lying opposite the rows of coupling elements 16, 17 are sewn on the outside of the fabric 1 and bridge an opening 24 in the fabric 1. The two fabric bands 18, 19 of the zipper 15 are followed by two stocking strips on the outside of the suit 20, 21 made of textile fabric. This stocking strips 20, 21 and the bands 18, 19 of the zipper 15 are sewn by sealed seams 10 on the outside of the fabric 1. The seams 10 are sealed by polyurethane welding bands.

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.How out FIG. 2 it can be seen, joins in the interior 6 of the suit under the opening 24 in the fabric 1 to a wall 22 enclosed space 23 at. The wall 22 is formed of an air- and waterproof material, such as plastic, in particular polyurethane-coated polyamide. The wall 22 is attached to the inside 11 of the fabric 1 via sealed seams 10. The wall 22 and the inner side 11 of the fabric 1 thus enclose a cavity 23 which, with the exception of the air-permeable zone 2 formed by the zipper 15, is air-tight and watertight with respect to the environment 7.

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.He is in FIG. 2 Room 23 located below the opening 24 merges into a venting channel 3 which extends from the chest area of the suit to approximately the shoulder 8 or the collar inside the protective suit ( FIG. 1 ). The vent channel 3 is tubular, wherein the tube walls are formed of the same material as the wall 22 of the cavity 23 and merge into one another. The located in the shoulder 8 and 9 of the collar end of the venting channel 3 is formed as an orifice 5, that this end of the venting channel 3 opens into the interior of the suit. The other end 4 of the venting channel 3 is located in the region of the space 23 and communicates with the air-permeable zone 2, that is in particular with the opening 24, in connection. In this way, an air exchange between the environment 7 and the interior 6 of the protective suit over the air-permeable zone 2 and through the venting channel 3 is ensured up to the 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 channel 3 from adhering to one another, an air-permeable spacer material 12 is introduced into the ventilation channel 3. This spacer material may be, for example, a foamed plastic or a nonwoven.

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 region of the space 23, in particular near the air-permeable zone 2, a water-absorbing medium 14 is introduced into the venting channel 3. This medium may be, for example, a polymer which forms a hydrogel on contact with water. This water-absorbing medium acts on entry of water through the air-permeable zone 2, ie in particular through the water-permeable zipper 15 and the opening 24, like a sponge and absorbs the incoming water. This avoids that when entering the water through the air-permeable zone 2, the water that has entered can flow through the venting channel 3 into the interior 6 of the suit. Only when the water-absorbing medium is saturated with moisture, the water that has entered can reach the upper area of the ventilation channel 3 and the mouth 5. When using superabsorbent media 14, the pilot can therefore be up to several hours in the water without water can penetrate through the vent channel 3 in the suit inside 6.

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.The FIG. 3 shows a preferred embodiment of the protective suit. Opposite the in FIG. 2 illustrated embodiment, this differs by an additional cover film 25 which is applied to the water-absorbing medium 14 in the region below the opening 24. The cover film 25 is impermeable to water and air and formed, for example, from a plastic film. In its edge regions it projects beyond the edges of the opening 24 and it is attached to these edge regions with the water-absorbing medium, for example by means of seams or adhesive strips. Should the water-absorbing medium 14 have reached saturation due to ingress of water, the water-absorbing medium 14 swells and thereby presses the covering film 25 into the region of the opening 24 and against the zipper 15. This prevents further penetration of water through the zipper 15.
