Das Material für den Trägergurt ist breit variierbar. Der Gurt kann zum Beispiel wie beschrieben aus in Textilstoff eingenähtem Schaumstoff gebildet sein, aber auch nur aus Gewebematerialien, aus elastischem Band oder aus handelsüblichen Gurten gebildet sein. Breite und Dicke können ebenfalls je nach Bedarf gewählt werden. Eine geeignete Breite ist zum Beispiel 1 bis 15 cm, vorzugsweise 2 bis 7,5 cm und insbesondere 3 bis 5 cm. Eine geeignete Dicke ist zum Beispiel 0,5 mm bis 2 cm, bevorzugt 2 mm bis 1 cm.The material for the carrier belt is widely variable. For example, the belt may be formed of foam sewn in fabric as described, but may also be formed only of fabric materials, elastic band, or commercially available straps. Width and thickness can also be selected as needed. A suitable width is, for example, 1 to 15 cm, preferably 2 to 7.5 cm and especially 3 to 5 cm. A suitable thickness is, for example, 0.5 mm to 2 cm, preferably 2 mm to 1 cm.
Bei einer Ausführungsform der Erfindung wird die Schwimmhilfsvorrichtung westenförmig aus Textilstoff gefertigt. Der Textilstoff wird mit einem dünnem Auftriebsmaterial (z.B. ca. 3- 5 mm) verbunden, z.B. durch Nähen oder Kleben, was vor allem die Optik positiv beeinflusst. Die Einzelteile werden dann miteinander vernäht, mit Auftriebsmaterial (z.B. geschlossenzellige Polyethylen- oder Polyurethan-Schaumstoffplatten, z.B. ca. 10 mm stark) gefüllt und geschlossen. Die Auftriebmaterialfüllung kann aus mehreren Platten bestehen, bis der gewünschte Auftrieb erreicht ist. Die Platten werden lose eingelegt, was eine größere Elastizität bewirkt. Materialeigenschaften der Platten wie Volumen, Materialart und Porosität sind so bemessen, daß hinreichend Auftrieb verliehen wird. Im Brustbereich und im oberen Rückenbereich wird die Füllung stärker ausgebildet, was den Körpergewichtsproportionen und dem gewünschtem Verhalten im Wasser besser entspricht. Ein stufenloses Einstellen am Körper wird mittels Klettband an den Seiten und im Schulterbereich möglich. Die seitlichen Einstellungen erfolgen mittels sich weit überlappenden Laschen 10 (
Ist die westenförmige Ausführungsform der erfindungsgemäßen Schwimmhilfsvorrichtung einmal für eine bestimmte Person eingestellt, so braucht diese künftig keine weiteren Einstellungen mehr vorzunehmen. Die Schwimmhilfe wird dann einfach wie eine Weste an- und ausgezogen. Das An- und Ausziehen sowie die Einstellung der Schwimmhilfe auf die jeweilige Körpergröße ist schnell und sicher zu handhaben.If the west-shaped embodiment of the swimming aid device according to the invention is set once for a certain person, then in future this person will no longer need to make any further adjustments. The buoyancy aid is then put on and taken off just like a vest. The on and off as well as the adjustment of the buoyancy aid to the respective body size can be handled quickly and safely.
