Definitions
- the invention relates to a life jacket with a float, which has a neck region with two adjoining breast areas, wherein the float of substantially U-, V- or ⁇ -shaped cut, stacked and formed at the edges via a weld interconnected airtight films and is provided with means for introducing or discharging air.
- the chosen personal buoyancy aid must ensure that the user is assisted in keeping the mouth and nose free of water, taking into account the expected conditions of use and the ability of the user to operate (eg, rough seas and waves), the use of waterproof and multi-layered clothing that itself (intentionally or unintentionally) creates additional buoyancy, or the use of extra weight equipment (eg, tool belt) can alter the performance of the personal buoyant.
- the chosen personal buoyancy aid must ensure that the user is assisted in keeping the mouth and nose free of water, taking into account the expected conditions of use and the ability of the user to operate (eg, rough seas and waves), the use of waterproof and multi-layered clothing that itself (intentionally or unintentionally) creates additional buoyancy, or the use of extra weight equipment (eg, tool belt) can alter the performance of the personal buoyant.
- EP 0 659 638 A1 is an inflatable life jacket with a collar-shaped neck piece and two adjoining breast panels known, which are connected to an inflatable one-piece float.
- outer parts of the thorax and the neck piece can be folded from the outside to the inside and in the region of the internal parts from the inside to the outside and can be held detachably in this position.
- the free ends of the pectoral wings are held over belt loops on a lap belt.
- the breast wings and the oppositely directed internal parts form a coherent air chamber, which has no constrictions.
- a rescue swimming collar in which a collar-shaped neck piece connects two chest wings to a one-piece, inflatable, horseshoe-shaped float.
- an additional buoyant body At the outer edge of a thorax is an additional buoyant body, which communicates via at least one gas passage with the interior of the chest wing.
- the known adoptedschwimmkragen inside a throttle point which is located at the transition region of the chest, to which the buoyancy adjoins the neck piece. This ensures that when inflating the strictlyschwimmkragens for a transitional period only a partial inflation of the thorax occurs with the subsequent buoyancy body, which should lead to a rotational movement of the person to be rescued in the water.
- the object of the invention is to improve a known life jacket to the effect that the head of a user is lifted in the inflated state further out of the water, as is the case with known life jackets.
- the lifejacket according to the invention is usually supplied together with a protective cover with automatic inflation. It also includes a harness with harness and back strap. For reasons of clarity, the protective cover and the harness, etc., however, are not shown; they are known to the skilled person anyway.
- FIG. 1 shows a first embodiment of a floating body in the plan view and in the uninflated state.
- the outer contour means the outer edge of the blank, while the inner, double line represents a weld seam 7, which indicates the beginning of the cavity, which can be filled by inflation with carbon dioxide, with air or with nitrogen.
- the floating body 1 is made of two superposed, congruent films made of an airtight material, which are sealed together along the weld 7.
- an airtight material for example polyurethane-coated nylon ® comes into question.
- FIG. 1 a float, which is formed by a neck region 2, connect to the two breast areas 3, 3 '.
- the neck region 2 surrounds a neckline 5, so that the breast regions 3, 3 'connect like the legs of an inverted U or like a horseshoe.
- the neck region 2 is adjoined by a neck pillow 4, which is in flow communication with the neck region 2 via two channels 10, 10 'and is therefore likewise inflatable.
- the outer edge of the film lying outside the weld 7 is extended to a tab 6, which is in the vicinity of its free bottom End has an eye 8.
- the eye 8 serves to keep the neck pillow 4 folded up in the inflated state and to fasten it, for example, to a further eye 8 'of the neck region 2.
- FIG. 1 a punching line 9, which separates the neck pillow 4 of the breast areas 3, 3 '.
- FIG. 2 shows the embodiment of FIG. 1 However, it can be seen that the tab 6 of the neck pillow 4 is fastened with its eye 8 to the eye 8 'of the neck region 2.
- FIG. 3 shows the life jacket in a perspective view in the inflated state, where you can clearly see the folded neck pillow 4.

Abstract
Description
Die Erfindung betrifft eine Rettungsweste mit einem Schwimmkörper, der einen Nackenbereich mit zwei daran anschließenden Brustbereichen aufweist, wobei der Schwimmkörper aus im wesentlichen U-, V- oder Ω-förmig zugeschnittenen, aufeinandergelegten und an den Rändern über eine Schweißnaht miteinander verbundenen luftdichten Folien gebildet und mit Mitteln zum Einleiten bzw. Ablassen von Luft versehen ist.The invention relates to a life jacket with a float, which has a neck region with two adjoining breast areas, wherein the float of substantially U-, V- or Ω-shaped cut, stacked and formed at the edges via a weld interconnected airtight films and is provided with means for introducing or discharging air.
Rettungswesten sollen den Träger im Wasser in eine stabile Rückenlage bringen, bei der die Atmungsöffnungen des Trägers deutlich aus dem Wasser gehoben werden, was nicht einfach erreichbar ist. Diesbezüglich heißt es in der gültigen Europäischen Norm EN 12402: "Das gewählte persönliche Auftriebsmittel muss sicherstellen, dass der Benutzer so unterstützt wird, dass unter Berücksichtigung der zu erwartenden Einsatzbedingungen und der Fähigkeit des Benutzers mitzuwirken, Mund und Nase vom Wasser freigehalten werden. Bestimmte Bedingungen (z.B. raue See und Wellen), der Gebrauch von wasserdichter und mehrschichtiger Kleidung, die selbst (beabsichtigt oder unbeabsichtigt) zusätzlichen Auftrieb erzeugt, oder der Gebrauch von Ausrüstung mit zusätzlichem Gewicht (z.B. Werkzeuggürtel) können die Leistungsfähigkeit des persönlichen Auftriebsmittels verändern."Life jackets should bring the wearer in the water in a stable supine position, in which the respiratory openings of the wearer are clearly lifted out of the water, which is not easy to reach. In this regard, the current European Standard EN 12402 states that: "The chosen personal buoyancy aid must ensure that the user is assisted in keeping the mouth and nose free of water, taking into account the expected conditions of use and the ability of the user to operate (eg, rough seas and waves), the use of waterproof and multi-layered clothing that itself (intentionally or unintentionally) creates additional buoyancy, or the use of extra weight equipment (eg, tool belt) can alter the performance of the personal buoyant.

Wie erwähnt, wird die erfindungsgemäße Rettungsweste üblicherweise zusammen mit einer Schutzhülle geliefert, an der ein Leibgurt und gegebenenfalls ein Rückengurt angebracht sind. Aus Gründen der Übersichtlichkeit ist die bekannte Schutzhülle jedoch nicht dargestellt.As mentioned, the lifejacket according to the invention is usually supplied together with a protective cover to which a waist belt and optionally a back strap are attached. For reasons of clarity, however, the known protective cover is not shown.
Die Schutzhülle nimmt den Schwimmkörper vor dem Gebrauch in zusammengefaltetem Zustand auf und schließt ihn ein. Dazu ist der Schwimmkörper vor dem Aufblasen auf besondere Art gefaltet, nämlich so, dass er ein flaches U mit gleichmäßig breiten Schenkeln bildet.The protective cover accommodates the floating body before use in a folded state and includes it. For this purpose, the float is folded before inflation in a special way, namely so that it forms a shallow U with uniformly wide legs.
Zum Verschließen der Schutzhülle über dem und um den Schwimmkörper herum dienen in einer Ausführungsform an der Schutzhülle angebrachte Klettverschlüsse, die beim Aufblasen der Rettungsweste aufreißen bzw. aufgesprengt werden und damit ein Entfalten der Schwimmkörper zulassen. In einer anderen Ausführungsform finden Druckknöpfe oder Reißverschlüsse mit Sollbruchstellen Verwendung zum Verschließen der Schutzhülle.To close the protective cover over and around the float around serve in one embodiment of the Protective cover attached Velcro fasteners, which are torn or blown up when inflating the lifejacket and thus allow unfolding of the floats. In another embodiment, push buttons or zippers with predetermined breaking points find use for closing the protective cover.
