Abstract

The inflatable lifejacket has at least one inflatable cushion around the neck opening and through its defined given shape and height comfortably fits round the neck of the wearer.

Description

For the functionality A lifejacket is the correct attachment to the rescued Person of elementary importance.

The Attachment of the vest on the body takes place by a belt system that the vest on the body of the person fixed, and by the design of the inner radius, where the lifejacket enclosing the neck of the person to be rescued.

The Fixation on the neck determines the swimming position to a special degree and thus the efficiency the vest.

So far, the neck diameter of the lifejacket in the construction was according to 1 arbitrarily given, which meant that a person with a low neck the life jacket rather little support offered and the distance between water surface and breathing holes (the "freeboard") decreased, while a person with a large neck diameter was partially restricted and complained of respiratory distress.

Here now grabs the one to be protected Invention, in which the inner radius of the lifejacket through additionally attached, inflatable cushion with defined shape and Height formed will, so the neck of the wearer independently is comfortably enclosed by its neck diameter.

From a technical point of view, this innovation means that the shape used to fix the neck is not, as hitherto, directly dependent on the system pressure of the lifejacket, but can be defined by the shape and design of the upholstery. So can at the in 3 pictured life jacket of the upper neck portion are relatively firmly inflated, while the connected by a digression inner part of the neck opening gently and safely holds the neck of the wearer.

At the in 2 pictured lifejacket is achieved by the pillow in the neck of a comfortable fixation of the neck in (with the vest worn front closed) laryngeal area.

In addition will Also the effect achieved is that the softer part of the inflatable cushions only at a pressure increase unfolded, which means that the rest of the lifejacket during the Inflation complete filled has been. It can thus be a kind of "sequential Inflation "reached in which the lifejacket only after complete filling of the main body through then afterwards following shaping of the inflation pads to their final position is brought.

One Another advantage of the above-described design of the neck hole is the possible now, unclothed vest off-white pack.

While always represented by the previous shape of the neck diameter, the inner fold line of the float ( 3 , solid black line), the design of the upholstery is a much Halsfernere, more open packing possible, which relieves the neck and the carrying feeling of the packed life jacket significantly improved (dashed line).

This is accordingly also in 2 to recognize.

• • eine bessere Faltmöglichkeit des Schwimmkörpers in der Schutzhülle
• • eine sichere und angenehmere Fixierung des Halses im Halsloch
• • eine gegenüber dem Gesamtschwimmkörper zeitlich verzögerte Halsfixierung

Due to the changed design of the neckline the following advantages are achieved:

• • a better folding possibility of the float in the protective cover
• • a secure and comfortable fixation of the neck in the neck hole
• • a time-delayed neck fixation compared to the total floating body
