  • the rescue device In order to reduce the packing volume, to achieve a stable packing position and to avoid cumbersome, regular checking procedures, it is known to provide the rescue device with the pressurized gas bottle with a casing under vacuum and to store it (DE-A-30 36 796). As long as this wrapping is still under vacuum, you can be sure that the rescue equipment is not damaged and that the compressed gas bottle still contains gas. If the rescue device has been damaged by an external pointed object, the casing is also damaged so that it loses its vacuum. If, on the other hand, compressed gas escapes from the compressed gas bottle, there can no longer be a vacuum in the casing. The absence of the vacuum can easily be determined, however, by the fact that the covering no longer tightly encloses the rescue device, but rather the package becomes soft and, depending on the extent of the leak, the covering loosely hangs from it sooner or later.

Description

Die Erfindung betrifft eine Einrichtung zum Auslösen einer Öffnungvorrichtung, die sich zusammen mit einem Rettungsgerät in einer unter Vakuum stehenden Umhüllung befindet und die durch Ziehen eines ersten von der Umhüllung umschlossenen Zugelementes die Umhüllung öffnet, wobei ein zweites sich außerhalb der Umhüllung erstreckendes Zugelement zum Übertragen einer Zugkraft auf das erste Zugelement vorgesehen ist.The invention relates to a device for triggering an opening device, which is located together with a rescue device in a casing which is under vacuum and which opens the casing by pulling a first traction element enclosed by the casing, a second traction element extending outside the casing for transmitting a Tractive force is provided on the first tension element.

Rettungsgeräte werden häufig in einer gasdichten, flexiblen Umhüllung, die unter Vakuum steht, aufbewahrt, da sie so viel weniger Platz benötigen. Durch das Vakuum wird das Rettungsgerät wie zum Beispiel ein Fallschirm oder ein aufblasbares Rettungsgerät wie eine Schwimmweste, eine Rettungsinsel, ein Rettungsboot oder dergleichen durch den auf der Umhüllung lastenden Außendruck zu einem festen und sehr kompakten Paket zusammengedrückt. Dabei kann das Volumen des verpackten Rettungsgerätes bis auf ein Drittel desjenigen Volumens verringert werden, das bei sorgfältigem Einpacken ohne Vakuum zu erreichen wäre. Außerdem besteht der Vorteil der festen Verpackung darin, daß sich einzelne Packlagen, das heißt einzelne Schichten des zusammengefalteten Rettungsgerätes nicht relativ zueinander verschieben können; das vakuumverpackte Paket ist vielmehr sehr formstabil.Rescue tools are often kept in a gas-tight, flexible envelope that is under vacuum because they take up so much less space. Due to the vacuum, the rescue device such as a parachute or an inflatable rescue device such as a life jacket, a life raft, a lifeboat or the like is compressed into a firm and very compact package by the external pressure on the casing. The volume of the packaged rescue device can be reduced to a third of the volume that would be achieved without vacuum when packing carefully. In addition, the advantage of the firm packaging is that individual packing layers, that is to say individual layers of the folded rescue device, cannot move relative to one another; the vacuum-packed package is rather very dimensionally stable.

Andererseits werden aufblasbare Rettungsgeräte, wie zum Beispiel Schwimmwesten, Rettungsinseln, Rettungsboote und dergleichen normalerweise mit einer Druckgasflasche zusammen aufbewahrt, so daß sie im Bedarfsfalle durch Betätigung des Ventils der Druckgasflasche schnell aufgeblasen werden können. Selbstverständlich ist es dabei erforderlich, in regelmäßigen Abständen zu prüfen, ob die Anordnung noch intakt ist. So müßte einmal geprüft werden, ob nicht Druck aus der Druckgasflasche entwichen ist. Andererseits müßte geprüft werden, ob das Rettungsgerät nicht möglicherweise durch äußere Beschädigung ein Leck aufweist.On the other hand, inflatable rescue equipment such as life jackets, life rafts, lifeboats and the like are normally stored together with a pressurized gas bottle, so that they can be inflated quickly if necessary by actuating the valve of the pressurized gas bottle. Of course, it is necessary to check at regular intervals whether the arrangement is still intact. So it would have to be checked whether pressure has not escaped from the gas cylinder. On the other hand, it would have to be checked whether the rescue device is possibly not leaking due to external damage.

Um das Packvolumen zu reduzieren, eine stabile Packlage zu erzielen und umständliche, regelmäßige Prüfvorgänge zu vermeiden, ist es bekannt, das Rettungsgerät mit der Druckgasflasche mit einer unter Vakuum stehenden Umhüllung zu versehen und aufzubewahren (DE-A-30 36 796). Solange wie diese Umhüllung noch unter Vakuum steht, kann man sicher sein, daß das Rettungsgerät nicht beschädigt ist und auch die Druckgasflasche noch Gas enthält. Ist nämlich das Rettungsgerät durch einen äußeren spitzen Gegenstand beschädigt worden, so ist die Umhüllung genauso beschädigt, so daß sie ihr Vakuum verliert. Entweicht andererseits Druckgas aus der Druckgasflasche, so kann in der Umhüllung kein Vakuum mehr vorhanden sein. Die Abwesenheit des Vakuums kann aber leicht dadurch festgestellt werden, daß die Umhüllung das Rettungsgerät nicht mehr eng umschließt, sondern das Paket weich wird und je nach Umfang des Lecks früher oder später die Umhüllung lose von demselben herabhängt.In order to reduce the packing volume, to achieve a stable packing position and to avoid cumbersome, regular checking procedures, it is known to provide the rescue device with the pressurized gas bottle with a casing under vacuum and to store it (DE-A-30 36 796). As long as this wrapping is still under vacuum, you can be sure that the rescue equipment is not damaged and that the compressed gas bottle still contains gas. If the rescue device has been damaged by an external pointed object, the casing is also damaged so that it loses its vacuum. If, on the other hand, compressed gas escapes from the compressed gas bottle, there can no longer be a vacuum in the casing. The absence of the vacuum can easily be determined, however, by the fact that the covering no longer tightly encloses the rescue device, but rather the package becomes soft and, depending on the extent of the leak, the covering loosely hangs from it sooner or later.

Soll das Rettungsgerät benutzt werden, so zieht man an einem Zugelement. Im Falle des Fallschirms wird dadurch die Umhüllung an einer Sollbruchstelle aufgerissen, so daß sich die Umhüllung mit Luft füllt, der Fallschirm eine lockerere Packung annimmt und daher aus der Umhüllung herausgezogen werden kann. Selbstverständlich kann dieses Herausziehen zum Beispiel beim Abwerfen von Lasten aus Flugzeugen auch automatisch erfolgen. Soll ein aufblasbares Rettungsgerät benutzt werden, so betätigt man das Ventil der Druckgasflasche mit Hilfe eines Zugelementes, das von außerhalb der Umhüllung ergriffen werden kann. Wenn das Rettungsgerät aufgeblasen wird, platzt dabei infolge des Drucks die Umhüllung und gibt so das Rettungsgerät frei.If the rescue device is to be used, pull a pulling element. In the case of the parachute, the covering is torn open at a predetermined breaking point, so that the covering fills with air, the parachute takes on a looser pack and can therefore be pulled out of the covering. Of course, this pulling out can also take place automatically, for example when dropping loads from aircraft. If an inflatable rescue device is to be used, the valve of the compressed gas cylinder is actuated with the aid of a pulling element which can be gripped from outside the casing. When the rescue device is inflated, the envelope bursts as a result of the pressure and thus releases the rescue device.

Das Zugelement, an dem ein Mensch ziehen muß oder auf das ein Zug von einem fremden Geräteteil ausgeübt wird, besteht normalerweise aus einem Seil, Draht oder dergleichen genügender Länge. Zweckmäßigerweise ist dieses Zugelement außerhalb der Umhüllung vorgesehen. Dabei besteht das Problem der Verbindung eines ersten innerhalb der Umhüllung angeordneten Zugelements, das mit dem Rettungsgerät oder einem damit verbundenen Teil, z. B. dem Ventil einer Druckgasflasche verbunden ist, mit dem zweiten Zugelement, das außerhalb der Umhüllung angeordnet ist, wobei die Verbindung unbedingt vakuumdicht sein sollte.The pulling element on which a person has to pull or on which a pull is exerted by an external device part normally consists of a rope, wire or the like of sufficient length. This tension element is expediently provided outside the casing. There is the problem of connecting a first tension element arranged within the envelope, which with the rescue device or a part connected thereto, for. B. the valve of a compressed gas bottle is connected to the second pulling element, which is arranged outside the casing, the connection should be absolutely vacuum-tight.

In der genannten Patentschrift wird dieses Problem dadurch gelöst, daß das erste Zugelement mit einer Schlaufe versehen ist, innerhalb derer eine Ringschweißung von zwei gegenüberliegenden Wänden der Umhüllung durchgeführt wird. Der Zentralbereich dieser Ringschweißung wird entfernt und durch ihn eine Schlaufe des zweiten Zugelementes hindurchgeführt, so daß das Innere der Umhüllung mit dem ersten Zugelement vakuumdicht von der Außenwelt und dem zweiten äußeren Zugelement getrennt ist. Es besteht aber das problem; daß eine zusätzliche Schweißung erfolgen muß, was nicht nur bei der Erstverpackung des Rettungsgerätes zusätzliche Arbeit mit einem besonderen ring- oder flächenförmigen Schweißstempel erfordert, sondern auch in allen den Fällen, in denen das Gerät nach Beschädigung der Umhüllung oder nach einer Kontrolle neu verpackt werden muß.This problem is solved in the cited patent specification in that the first tension element is provided with a loop, within which an annular weld is carried out from two opposite walls of the casing. The central area of this ring weld is removed and a loop of the second tension element is passed through it, so that the inside of the casing with the first tension element is separated from the outside world and the second outer tension element in a vacuum-tight manner. But there is the problem; that an additional welding must take place, which not only requires additional work with a special ring-shaped or flat-shaped welding stamp when the rescue device is first packed, but also in all cases in which the device has to be repacked after damage to the casing or after a check .

Die Aufgabe der Erfindung besteht darin, ein aufblasbares Rettungsgerät der eingangs genannten Art mit Umhüllung zu schaffen, bei der auf einfachere Weise eine vakuumdichte zugfeste Verbindung zwischen erstem (innerem) und zweitem (äußerem) Zugelement hergestellt werden kann.The object of the invention is to provide an inflatable rescue device of the type mentioned with a cover, in which a vacuum-tight connection between the first (inner) and second (outer) pulling element can be produced in a simpler manner.

Die erfindungsgemäße Lösung besteht darin, daß das erste Zugelement sich in einem schlauchförmigen Ansatz der Umhüllung erstreckt und an seiner von der Öffnungsvorrichtung entfernten Stelle mit einer Verdickung versehen oder verbunden ist, deren senkrecht zur Erstreckungsrichtung des ersten Zugelements angeordnete Querschnittsfläche wesentlich größer ist als die des ersten Zugelements, und daß um das erste Zugelement zwischen Öffnungsvorrichtung und Verdickung, unter Einschluß des schlauchförmigen Ansatzes der Umhüllung das zweite Zugelement mit einer Schlaufe gelegt ist, deren Querschnittsfläche größer ist als die des ersten Zugelements und kleiner als die der Verdickung.The solution according to the invention consists in that the first tension element extends in a tubular extension of the casing and is provided or connected with a thickening at its point remote from the opening device, the cross-sectional area of which is perpendicular to the direction of extension of the first tension element and is substantially larger than that of the first Tension element, and that around the first tension element between the opening device and thickening, including the tubular extension of the casing, the second tension element is placed with a loop, the cross-sectional area of which is larger than that of the first tension element and smaller than that of the thickening.

Das erste Zugelement ist also an einem schlauchförmigen Ansatz der Umhüllung angeordnet, der bereits bei der Herstellung der Umhüllung erzeugt werden kann. Das erste Zugelement weist eine Verdickung auf, hinter die die Schlaufe des zweiten Zugelementes faßt. Zwischen erstem und zweitem Zugelement befindet sich dabei ein Teil des schlauchförmigen Ansatzes der Umhüllung; eine zusätzliche Schweißung muß hierfür die Verbindung nicht durchgeführt werden. Es braucht lediglich eine Schlaufe des zweiten Zugelementes himter der Verdickung um das erste Zugelement gelegt und gesichert werden, was bei einem Drahtseil durch eine Metallklammer, bei einem Kunststoffseil durch eine Vernähung geschehen kann. Auch das erste Zugelement kann ein Seil oder ein Drahtseil sein.The first tension element is therefore arranged on a tubular extension of the casing, which can already be produced during the manufacture of the casing. The first tension element has a thickening behind which the loop of the second tension element grips. Between the first and second tension element there is a part of the tubular extension of the casing; an additional weld does not have to be carried out for this. All that is required is a loop of the second tension element behind the thickening around the first tension element and secured, which can be done with a wire rope by a metal clip, with a plastic rope by sewing. The first tension element can also be a rope or a wire rope.

Die Verdickung des ersten Zugelements kann z. B. ein Knoten sein. Damit die Verdickung aber leicht groß genug gemacht werden kann, um eine sichere Funktion auch bei nicht zu enger Schlaufe des zweiten Zugelementes sicherzustellen, kann die Verdickung ein separates Element mit einer umlaufenden Nut sein, in die eine Schlaufe des ersten Zugelements eingelegt ist. Diese Schlaufe ist dabei ähnlich wie die entsprechende Schlaufe des zweiten Zugelements gegen unbeabsichtigtes Öffnen zu sichern.The thickening of the first tension element can, for. B. be a knot. So that the thickening can easily be made large enough to ensure reliable functioning even when the loop of the second tension element is not too tight, the thickening can be a separate element with a circumferential groove into which a loop of the first tension element is inserted. This loop is to be secured in a similar way to the corresponding loop of the second tension element against unintentional opening.

Als separates Element kann z. B. eine Kugel, eine Scheibe oder ein T-förmiges Bäuteil verwendet werden. Dieses Bauteil kann statt mit Rillen auch mit Bohrungen zur Aufnahme des ersten Zugelementes versehen sein. Es könnte auch aus zwei größeren Teilen bestehen, die durch eine Schraube zusammengehalten werden, wobei dann eine Schlaufe des ersten Zugslementes zwischen den beiden Einzelteilen der Verdickung festgeschraubt werden kann. Dabei können auch Vorkehrungen getroffen sein, daß mehr als ein Zugelement mit der Verdickung verbunden werden kann, wenn das Entfernen des Rettungsgerätes aus der Umhüllung mehr als ein solches Zugelement erfordert.As a separate element, e.g. B. a ball, a disc or a T-shaped component can be used. Instead of grooves, this component can also be provided with bores for receiving the first tension element. It could also consist of two larger parts, which are held together by a screw, in which case a loop of the first tension element can be screwed tight between the two individual parts of the thickening. Provisions can also be made that more than one tension element can be connected to the thickening if the removal of the rescue device from the casing requires more than one such tension element.

Falls die zu rettende Person, das heißt das äußere Zugelement immer mit dem Rettungsgerät verbunden sein soll, kann vorgesehen sein, daß die Verdickung mit einer Verbindungsleine mit dem Rettungsgerät verbunden ist, wobei die Schlaufe des zweiten Zugelements auch die Verbindungsleine umschließt.If the person to be rescued, that is to say the outer pulling element is always to be connected to the rescue device, it can be provided that the thickening is connected to the rescue device with a connecting line, the loop of the second pulling element also enclosing the connecting line.

Da die Umhüllung im Normalzustand einen größeren Umfang als die Verdickung haben muß, muß die Umhüllung hinter der Verdickung durch die Schlaufe des zweiten Zugelements zusammengerafft werden. Vorteilhafterweise erfolgt dieses Zusammenraffen aber nicht erst durch das äußere Zugelement, sondern durch eine äußere Umschnürung oder dergleichen, die bereits vor dem Evakuieren angebracht werden kann. Diese äußere Umschnürung ist dabei zwischen der Öffnungsvorrichtung und der Verdickung um das erste Zugelement vorgesehen. Diese äußere Umschnürung besteht vorteilhafterweise aus einem Klebeband. Nach dem Evakuieren fixiert sich diese Zusammenraffung durch das Vakuum von selbst. Das Klebeband hat nur eine Hilfsfunktion für den Vorgang des Evakuierens.Since the covering must have a larger circumference than the thickening in the normal state, the covering behind the thickening must be gathered up by the loop of the second tension element. Advantageously, this gathering does not take place first through the outer traction element, but rather through an outer strapping or the like, which can be attached before the evacuation. This outer constriction is provided between the opening device and the thickening around the first tension element. This outer strapping advantageously consists of an adhesive tape. After evacuation, this gathering is fixed automatically by the vacuum. The adhesive tape only has an auxiliary function for the process of evacuation.

Wird am zweiten, äußeren Zugelement gezogen, um das Ventil der Druckflasche eines aufblasbaren Rettungsgeräts, z. B. einer Schwimmweste, Rettungsinsel oder dergleichen zu öffnen, so muß normalerweise nicht nur die notwendige Zugkraft auf das erste Zugelement ausgeübt werden, sondern auch die Umhüllung im Bereich des schlauchförmigen Ansatzes zerrissen werden, falls diese Umhüllung hier glatt liegt. Diese zusätzliche Kraft kann bei entsprechend starken Umhüllungen, wie sie insbesondere für größere Rettungsgeräte wie Rettungsinseln erforderlich sind, sehr beträchtlich sein und möglicherweise ein sicheres Öffnen verhindern. Um dies zu vermeiden, kann die Umhüllung im Bereich des ersten Zugelements eine in Längsrichtung derselben sich erstreckende Zusammenraffung aufweisen, die beim Ziehen am zweiten Zugelement auseinandergezogen und gestreckt wird, so daß zum Öffnen des Ventils die Umhüllung hier nicht zerrissen werden muß.Is pulled on the second, outer tension element to the valve of the pressure bottle of an inflatable rescue device, for. B. to open a life jacket, life raft or the like, normally not only the necessary tensile force must be exerted on the first tension element, but also the covering in the area of the tubular extension must be torn if this covering lies smooth here. This additional force can be very considerable in the case of appropriately strong casings, as are required in particular for larger rescue devices such as life rafts, and possibly prevent a safe opening. In order to avoid this, the covering in the region of the first pulling element can have a gathering which extends in the longitudinal direction thereof and which is pulled apart and stretched when the second pulling element is pulled, so that the covering does not have to be torn here to open the valve.

Die Falten der Zusammenraffung können dabei z. B. durch einen Faden, ein Garn oder einen Druckknopf zusammengehalten werden, das bzw. der durch Löcher außerhalb der Schweißnaht geführt ist. Der Faden oder das Garn kann so dimensioniert sein, daß es bei einem Zug am zweiten Zugelement leicht zerreißt (Sollbruchgarn). Da diese Raffung primär nur während des Evakuierens fixiert werden muß und sie sich danach selbst fixiert, kann der Faden, das Garn oder der Druckknopf anschließend auch entfernt werden.The folds of the gathering can z. B. are held together by a thread, a yarn or a push button which is guided through holes outside the weld. The thread or the yarn can be dimensioned so that it tears easily when pulling on the second tension element (predetermined breaking yarn). Since this gathering only has to be fixed primarily during the evacuation and then fixes itself, the thread, the thread or the push button can also be removed afterwards.

Bei Lagerung und Transport kann die äußere Umhüllung wirkungsvoll gegen Beschädigung gesichert werden, wenn die äußere Umhüllung durch einen Hartschaummantel umgeben ist, der ebenso wie die Umhüllung selbst bei Aufblasen des Rettungsgerätes abplatzt.During storage and transport, the outer covering can be effectively secured against damage if the outer covering is surrounded by a hard foam jacket which, like the covering, flakes off even when the rescue device is inflated.

Die Erfindung wird im folgenden anhand einer vorteilhaften Ausführungsform unter Bezugnahme auf die beigefügten Zeichnungen beschrieben. Es zeigen:

  • die Fig. 1 bis 3 die fortschreitende Herstellung der Verbindung zwischen einem ersten (inneren) und einem zweiten (äußeren) Zugelement.
The invention is described below using an advantageous embodiment with reference to the accompanying drawings. Show it:
  • 1 to 3 the progressive establishment of the connection between a first (inner) and a second (outer) tension element.

In Fig. 1 ist eine Umhüllung 1 gezeigt, die bei 2 einen schlauchförmigen Ansatz aufweist. In der Nähe des Randbereiches 3 der Umhüllung 1 ist dabei eine vakuumdichte, umlaufende Schweißnaht 4 vorgesehen.In Fig. 1 an envelope 1 is shown, which has a tubular extension at 2. A vacuum-tight, all-round weld seam 4 is provided in the vicinity of the edge region 3 of the casing 1.

In den schlauchförmigen Ansatz 2 sind die Betätigungsorgane für ein Ventil 5 eingeführt, nämlich zwei erste oder innere Zugseile 6, die um eine Verdickung 7, im folgenden Schlaufenhalter genannt, schlaufenförmig herumgeführt sind, wobei die Schlaufen mit Hilfe von Metallklammern 8 oder dergleichen geschlossen sind. Außerdem ist um den Schlaufenhalter 7 in ähnlicher Weise eine Verbindungsleine 9 zwischen dem nicht gezeigten Rettungsgerät und dem Schlaufenhalter 7 befestigt. Der Schlaufenhalter 7 besteht dabei aus zwei Teilen, die durch eine Schraube 10 zusammengeschraubt werden können, so daß die Schlaufen der Zugelemente 6 und des Verbindungsseils 9 bereits vorher hergestellt werden können. Im Randbereich 3 des schlauchförmigen Ansatzes 2 sind mehrere übereinander liegende Löcher 11 vorgesehen, durch die ein Faden oder ein Garn 12 hindurchgezogen ist.In the tubular extension 2, the actuators for a valve 5 are introduced, namely two first or inner traction cables 6, which are looped around a thickening 7, hereinafter called loop holder, the loops being closed with the aid of metal clips 8 or the like. In addition, a connecting line 9 is fastened in a similar manner around the loop holder 7 between the rescue device (not shown) and the loop holder 7. The loop holder 7 consists of two parts that can be screwed together by a screw 10, so that the loops of the tension elements 6 and the connecting cable 9 can be made beforehand. In the edge area 3 of the tubular extension 2, a plurality of holes 11 are provided, one above the other, through which a thread or a yarn 12 is drawn.

In Fig. 2 ist gezeigt, wie direkt unterhalb des Schlaufenhalters 7 der schlauchförmige Ansatz 2 durch ein Klebeband 13 zusammengerafft und in dieser zusammengerafften Stellung fixiert worden ist. Anschließend kann der schlauchförmige Ansatz 2 im Bereich der Löcher 11 zusammengerafft werden, wobei diese Zusammenraffung 14 bzw. ihre Falten durch Anziehen und Verknoten der Garne 12 gesichert werden können. Anschließend kann die Umhüllung 1, nachdem sie auf der Seite zugeschweißt worden ist, von der das Rettungsgerät mit den genannten Einrichtungen eingeführt wurde, evakuiert werden.In Fig. 2 it is shown how directly below the loop holder 7 the tubular extension 2 is gathered together by an adhesive tape 13 and fixed in this gathered position. The tubular extension 2 can then be gathered in the area of the holes 11, this gathering 14 or its folds being secured by tightening and knotting the yarns 12. The casing 1 can then be evacuated after it has been welded to the side from which the rescue device with the aforementioned devices was inserted.

Dieser Zustand ist in Fig. 3 gezeigt, der insbesondere die Falten der Zusammenraffung 14 zeigt, die durch die verknoteten Garne 12 zusammengehalten sind. Anschließend kann dann das zweite (äußere) Zugelement 15 mit einer Schlaufe 16 um die ersten (inneren) Zugelemente 6 im Bereich des Klebebandes 13 herumgelegt werden, wobei dann die Schlaufe 16 bei einem Kunststoffseil zum Beispiel durch Vernähung 17 gegen ein unbeabsichtigtes Öffnen gesichert werden kann. Zieht man an dem zweiten Zugelement 15, so braucht die Umhüllungsfolie 1 nicht zerrissen zu werden, da die Sollbruchgarne 12 zerreißen und dadurch die Falten freigeben, so daß sie gestreckt werden können. Durch die Zugkraft braucht dann nur noch das Ventil 5 geöffnet zu werden, wodurch das Rettungsgerät aufgeblasen wird und wodurch erst in diesem Moment die bisher vakuumdichte Umhüllung 1 zerstört wird.This state is shown in FIG. 3, which shows in particular the folds of the gathering 14, which are held together by the knotted yarns 12. The second (outer) tension element 15 can then be placed around the first (inner) tension elements 6 in the region of the adhesive tape 13 with a loop 16, in which case the loop 16 can be secured against unintentional opening in the case of a plastic rope, for example by sewing 17 . If you pull the second pulling element 15, the wrapping film 1 does not need to be torn, since the predetermined breaking yarns 12 tear and thereby release the folds so that they can be stretched. The pulling force then only needs to open the valve 5, as a result of which the rescue device is inflated and as a result of which the previously vacuum-tight envelope 1 is destroyed only at this moment.
