Abstract
The invention relates to a life jacket or rescue vest comprising a U-shaped base body (1) which can put around the neck of a wearer when in use and its two sides (2, 3) lie on the chest of a wearer. The base body (1) is made of two congruent, airtight layers (11, 12) made of a textile material and is provided with a plastic covering on one side. Both layers (11, 12) are bonded together on the edge (6) and comprise at least one opening (7) on which a valve is connected to an air inlet or an air outlet. A gusset or an insert is introduced into each of the two sides (2, 3) between the two layers (11, 12), and the distance between the two layers (11, 12) increases when the life jacket is inflated, thus increasing the volume of air in the region of the free ends of the sides.
Description
Beschreibung description
SCHWIMM - ODER RETTUNGSWESTESWIMMING OR RESCUE VEST
Schwimmwesten sollen den Träger im Wasser in eine stabile Rückenlage bringen, bei der die Atmungsoffnungen des Tragers deutlich aus dem Wasser gehoben werden. Während dies in normaler Bekleidung meist sehr einfach erreicht werden kann, behindert wasserdichte Wetterschutzbekleidung durch die enthaltenen Lufteinschlüsse das Drehen in die RückenlageLife jackets should bring the wearer in the water into a stable supine position, in which the respiratory openings of the wearer are clearly lifted out of the water. While this can usually be achieved very easily in normal clothing, waterproof weatherproof clothing hampers rotation into the supine position due to the air inclusions it contains
Dieses Verhalten ist allgemein bekannt und wird auch in der gültigen Norm EN ISO 12402 erwähnt: Die angegebene Auftriebskraft und ihre Verteilung sollten sicherstellen, daß der Träger so unterstützt wird, daß sein Mund und seine Nase aus dem Wasser herausragen und daß er eine geeignete stabile Schwimmlage mit nach hinten geneigtem Rumpf einnimmt. Bestimmte Umstände können das Verhalten ändern, so z.B. Wellen oder das Tragen von Bekleidung, die selbst beabsichtigt oder unbeabsichtigt zusätzlichen Auftrieb verursacht, oder beim Tragen von Kälteschutzanzügen.This behavior is well known and is also mentioned in the current standard EN ISO 12402: The stated buoyancy and its distribution should ensure that the wearer is supported so that his mouth and nose protrude from the water and that he has a suitable stable floating position with leaning back hull occupies. Certain circumstances may change the behavior, e.g. Waves or wearing clothing that intentionally or unintentionally causes additional buoyancy, or when wearing cold weather suits.
Bisher wurden verschiedene Ansätze zur Verbesserung des Drehverhaltens verfolgt, z.B. durch den Einsatz eines großvolumigen, eventuell auch asymmetrischen Schwimmkörpers oder der Kombination von mindestens zwei Schwimmkörpern aufeinander.So far, various approaches have been followed to improve the rotational behavior, e.g. through the use of a large-volume, possibly also asymmetrical floating body or the combination of at least two floating bodies on each other.
Um die Geometrie eines Schwimmkörpers in seiner Hohe zu verändern, wurden in der Vergangenheit auch zusätzliche, verschweißte Ringe im Halsbereich eingesetzt.In order to change the geometry of a floating body in its height, additional, welded rings were used in the neck in the past.
Aufgabe der Erfindung ist es, die bekannten Schwimmwesten dahingehend zu verbessern, daß eine noch bessere Drehwirkung bei kompaktem Sitz und besonders kompakter Bauweise erreicht wird.The object of the invention is to improve the known lifejackets to the effect that an even better rotational effect is achieved with a compact seat and a particularly compact design.
Zur Lösung dieser Aufgabe dient eine Schwimmweste mit den Merkmalen des Anspruchs 1
Dadurch kann ein Schwimmkörper so gestaltet werden, daß sein Volumen im Bereich des Brustbein mit einem möglichst großen Abstand zur Korperachse konzentriert ist.To solve this problem is a life jacket with the features of claim 1 Thereby, a float can be designed so that its volume is concentrated in the region of the sternum with the greatest possible distance to the body axis.
Durch die Einfügung eines Einsatzes in jeden Schenkel der Schwimmweste wird die Geometrie des Schwimmkörpers nämlich so gestaltet, daß sich Teile des Schwimmkörpers gegenüber der Gesamtform beim Aufblasen anders verhalten und auf diese Weise eine zusatzliche Hohe in diesem Bereich erreicht werden kann. Die gewünschte Form des Schwimmkörpers ist hierbei abhangig von der Große und der Position des Einsatzes.By inserting an insert into each leg of the life jacket, the geometry of the float is namely designed so that behave different parts of the float relative to the overall shape during inflation and in this way an additional height can be achieved in this area. The desired shape of the float is dependent on the size and the position of the insert.
Des weiteren kann die Geometrie des Schwimmkörpers durch einen oder mehrere im Inneren des Schwimmkörpers angebrachten Stege beeinflußt werden, durch die eine Verbindung zwischen der Innenseite des Schwimmkörpers und dem gefalteten Einsatz hergestellt wird, und mit dem die Form des eingesetzten Teils in ihrer Ausdehnung begrenzt werden kannFurthermore, the geometry of the float can be influenced by one or more webs mounted inside the float, by which a connection between the inside of the float and the folded insert is made, and with which the shape of the inserted part can be limited in their extent
Die neue Gestaltung der Schwimm- oder Rettungsweste bietet somit eine sehr gute Drehwirkung bei bequemem Sitz und besonders kompakter Packweise.The new design of the swimming or life jacket thus provides a very good turning effect with a comfortable fit and very compact pack.
Die Erfindung wird nachfolgend anhand einer Zeichnung naher erläutert; es zeigen:The invention will be explained in more detail with reference to a drawing; show it:
Figur 1 eine schematische Ansicht einer ersten Ausfuhrungsform der Erfindung; Figur 2 einen Einsatz oder Zwickel;Figure 1 is a schematic view of a first embodiment of the invention; FIG. 2 shows an insert or gusset;
Figur 3 eine zweite Ausfuhrungsform der Erfindung; undFIG. 3 shows a second embodiment of the invention; and
Figur 4 einen Schnitt entlang der Linie A-A aus Figur 3.FIG. 4 shows a section along the line A-A from FIG. 3.
Es wird darauf hingewiesen, daß bei den beiden nachfolgend beschriebenen Aus fuhrungsformen gleiche Teile mit gleichen Bezugszeichen versehen sind.It should be noted that in the two embodiments described below, the same parts are provided with the same reference numerals.
Figur 1 zeigt eine Ansicht einer Schwimm- oder Rettungsweste mit einem Grundkorper 1, der im wesentlichen die Form eines umgekehrten U mit zwei Schenkeln 2 und 3 hat, die über einen Nackenbereich 4 miteinander verbunden sind und dabei eine Halsoffnung 5 freilassen. Im Gebrauch liegen die beiden Schenkel 2 und 3 auf dem Brust-
bein oder Sternum eines nicht gezeigten Trägers oder einer Trägerin auf.Figure 1 shows a view of a swimming or life jacket with a base body 1, which has substantially the shape of an inverted U with two legs 2 and 3, which are connected to each other via a neck region 4 and thereby leave a neck opening 5. In use, the two legs 2 and 3 lie on the chest leg or sternum of a wearer, not shown.
Der Grundkörper 1 wird aus zwei deckungsgleichen Lagen von Tex- tilmaterial gebildet, die einseitig mit einer luftundurchlässigen Schicht, beispielsweise Polyurethan (PU), beschichtet sind. Die beiden Lagen werden mit ihren PU-beschichteten Seiten auf einander gelegt und entlang des Randes 6 miteinander verschweißt oder verklebt. Durch eine Öffnung 7 kann Luft eingeblasen werden, um einen Schwimmkörper zu bilden.The base body 1 is formed from two congruent layers of textile material which are coated on one side with an air-impermeable layer, for example polyurethane (PU). The two layers are placed with their PU-coated sides on each other and welded or glued together along the edge 6. Through an opening 7, air can be injected to form a float.
Gemäß Erfindung ist nun zwischen die beiden Lagen des Grundkörpers 1 im Bereich der freien, einander zugewandten Enden der Schenkel 2 und 3 je ein Zwickel oder Einsatz 8 eingesetzt, der bis zum Rand 6 verläuft und an einer Faltlinie 9 endet. Jeder der beiden Zwickel oder Einsätze 8 ist ebenfalls aus einem einseitig mit luftundurchlässiger Beschichtung, beispsielsweise PU, versehenem Textilmate- rial gebildet und so eingebracht, daß bei fertiger Schwimmweste die textile Seite nach außen, die PU-Beschichtung hingegen nach innen gerichtet ist.According to the invention, a gusset or insert 8 is now inserted between the two layers of the main body 1 in the region of the free, mutually facing ends of the legs 2 and 3, which extends to the edge 6 and ends at a fold line 9. Each of the two gussets or inserts 8 is also formed from a one-sided airtight coating, for example, PU, provided Textilmate- material and introduced so that in finished life jacket, the textile side to the outside, the PU coating, however, is directed inwards.
Figur 2 zeigt den Einsatz 8 mit der Faltlinie 9. Wenn der Einsatz 8 entlang der Faltlinie 9 so gefaltet wird, daß die textile Seiten aufeinander liegen und die PU-beschichtet Seiten nach außen zeigen, dann kann der Einsatz zwischen die beiden Lagen des Grundkörpers 1 so eingebracht werden, daß jeweils PU-Schichten einander zugewandt sind und damit ein Verschweißen entlang des Randes 6 erfolgen kann. In jedem Schenkel 2, 3 ist ferner ein Steg 10 zwischen den beiden Lagen aus beschichtetem textilem Gewebe eingebracht, der an einem Ende im Bereich der Faltlinie 9 mit dem Einsatz 8 und am gegenüberliegenden anderen Ende mit dem Rand 6 des Grundkörpers 1 verschweißt ist. Des Vorsehen des Stegs 10 ist jedoch nur eine optionale Maßnahme; sie ist also nicht in jedem Fall absolut erforderlich und kann gegebenenfalls auch weggelassen werden.Figure 2 shows the insert 8 with the fold line 9. When the insert 8 along the fold line 9 is folded so that the textile sides lie on each other and the PU-coated sides facing outward, then the insert between the two layers of the main body. 1 be introduced so that each PU layers are facing each other and thus welding along the edge 6 can be done. In each leg 2, 3, a web 10 between the two layers of coated textile fabric is further introduced, which is welded at one end in the region of the fold line 9 with the insert 8 and at the opposite other end to the edge 6 of the base body 1. However, the provision of the web 10 is only an optional measure; It is therefore not absolutely necessary in any case and can be omitted if necessary.
Figur 3 zeigt eine zweite Ausführungsform der Erfindung, bei der je ein Zwickel oder Einsatz 8 in jeden der beiden Schenkel 2 und 3 so eingelegt ist, dass seine Faltlinie 9 nicht schräg über die beiden Schenkel 2 und 3 verläuft, wie dies bei der ersten Ausführungsform nach Figur 1 der Fall ist, sondern im rechten Winkel zu einer Symmetrieachse S. Entlang des Randes 6 sind die beiden Zwik-
kel oder Einsatze 8 mit der oberen und unteren Lage 11 und 12 des Grundkorpers 1 verschweißt. Außerdem ist im Nackenbereich 4 eine Trennfolie 13 zwischen der oberen Lage 11 und der unteren Lage 12 eingebracht, die ebenfalls im Bereich des Randes 6 mit dem Grund- korper 1 verschweißt und im Bereich der Faltlinie 9 mit den Einsatzen 8 entlang einer Naht 14 fest verbunden ist, so dass die Trennfolie 13 zusammen mit den Einsatzen 8 im Grundkorper 1 eine obere Luftkammer 15 und eine untere Luftkammer 16 bilden, die getrennt aufblasbar sind. Zum Einleiten von Luft in die obere Kammer 15 dient ein nicht dargestelltes erstes Ventil, das auf der Oberseite des rechten Schenkels 3 angeordnet ist und an die dort befindliche Öffnung 7 angeschlossen ist. Zum Aufblasen der unteren Kammer 16 dient ein zweites, ebenfalls nicht dargestelltes Ventil, das an der Unterseite des Grundkorpers 1 im Bereich des linken Schenkels 2 vorgesehen und an die gestrichelt angedeutete Öffnung 7 angeschlossen ist.Figure 3 shows a second embodiment of the invention, in each of which a gusset or insert 8 in each of the two legs 2 and 3 is inserted so that its fold line 9 is not oblique over the two legs 2 and 3, as in the first embodiment is the case, but at right angles to a symmetry axis S. Along the edge 6, the two Zwik- Kel or inserts 8 with the upper and lower layer 11 and 12 of the main body 1 welded. In addition, in the neck region 4, a release film 13 is introduced between the upper layer 11 and the lower layer 12, which also welded in the region of the edge 6 with the base body 1 and fixedly connected in the region of the fold line 9 with the inserts 8 along a seam 14 is, so that the release film 13 together with the inserts 8 in the base body 1 form an upper air chamber 15 and a lower air chamber 16, which are separately inflatable. For introducing air into the upper chamber 15 is a not shown first valve, which is arranged on the upper side of the right leg 3 and is connected to the opening 7 located there. To inflate the lower chamber 16 is a second, also not shown valve, which is provided on the underside of the main body 1 in the region of the left leg 2 and connected to the opening 7 indicated by dashed lines.
Figur 4 zeigt einen Schnitt entlang der Linie A-A von Figur 3 und verdeutlicht die eben beschriebenen Verhaltnisse, insbesondere die Ausbildung der beiden Kammern 15 und 16 im Grundkorper 1 und deren Trennung durch die Zwickel oder Einsatze 8.FIG. 4 shows a section along the line A-A of FIG. 3 and illustrates the conditions just described, in particular the design of the two chambers 15 and 16 in the base body 1 and their separation through the gussets or inserts 8.
