The invention relates to a life jacket having a plurality of compartments substantially delimited by a coating material or the like with a lighter, more supportable, granular or particulate material than water, the volume of which is substantially less than the compartment volume, the granular material in the compartment being loosely arranged and within the department.

10 Life jackets use a lighter material than water, eg gas or foamed foam such as cellular polystyrene. In particular, life jackets made of foamed cellular polystyrene or the like are difficult to wear because they are inelastic, at least in those parts which contain the aforementioned cellular polystyrene shaped as a compartment-filling shaped body. It can be generally said that a life jacket is always worn in the hope that it will not be used for its actual purpose. When the life jacket is on, various activities are often performed that would require freedom of movement, for example in sailing, hunting and fishing, as well as in various work tasks performed on water bodies. The current life jackets in the country do not provide a satisfactory solution to this problem, but their use restricts freedom of movement and thus the performance of functions.

The object of the present invention is to provide a new 3 ° floating device solution, which provides considerable advantages over previous solutions. To achieve this object, the floating device according to the invention 2 75774 is mainly characterized in that the granular material is cellular polystyrene, polyurethane or a similar foamed plastic. The granularity makes it possible for the material in the compartment to adapt to the body of the individual and to be flexible, for example in the case of life jackets, according to the functions to be performed. In addition, the adaptation and pressing of the floating means tightly to the body, e.g. in the case of a life jacket, makes it possible for the life jacket to be a warm garment and, for example, an outdoor suit to be placed on top of the life jacket. In addition, cellular polystyrene, polyurethane or similar foamed plastic as a granular material makes the life jacket fireproof.

The invention is illustrated in the following by referring to the so-called embodiment shown in the accompanying drawing. veneliivistä. In the drawing, Fig. 1 shows a front view of a boat vest worn on top, Fig. 2 shows a boat vest of Fig. 1 also dressed on top, and Fig. 3 shows a section III-III of Fig. 2.

The boat vest according to the drawing is sleeveless and opens at the front. It is fastened to the body using belts 1 25 and 2 which are fastened to the vest by means of threaded pieces 3. The belts have buckles 4 for tightening the belts.

According to the invention, the vest is divided into compartments. The coating material is a fabric or the like treated with a flame retardant. The vest is formed of a fabric cut to the shape of a vest and sewn together at the edges using edge reinforcements. In addition, in order to form compartments in particular, the fabrics are sewn together with intermediate stitches. Each compartment is partially filled with a loose, granular or particulate material 10 lighter than water.

In particular, in Figure 1, the front pieces 5, 6 each have two compartments 01 and 02 formed using a horizontal stitch 7. In particular, in Figure 2, the ta-15 piece 8 has four compartments 03-06 formed by intersecting stitches, using a vertical stitch 9 and a horizontal stitch 10. There is no granular material on the sides because it is a boat vest. The lower compartments 05 and 06 are bounded on the sides by side stitches 11 and 12. 20 The compartments are bounded at the edges of the vest by edge reinforcements 13.

The granular material may be, for example, cellular polystyrene, polyurethane or other similar foamed form.

Figure 3 is a sectional view of the structure of the boat vest. The inner wall 14 and outer wall 15 of the coating material, together with the edge reinforcements 13 and the intermediate joints 30, delimit compartments 04 and 06 with granular material M. Because the loose, granular or particulate material partially fills compartments 04 and 06, . In this way, the 35 boat vest is adaptable and warm according to the user's movements.

The buoyancy vest can also be formed using the partitioning principle described above, so that the vest comprises a neck compartment filled with granular material and a rib compartment located on the left side. 5 Such a buoyancy aid keeps the unconscious person on his side with the left side up and the head resting on the neck section, so that suffocation cannot occur. Because there are several compartments, the vest will not lose its support, even if one or more of the compartments were damaged and emptied.

EXAMPLE

An exemplary vest in practice comprises a cover fabric of 100% polyamide treated with a flame retardant and the granular material is spherical 2-8 mm diameter cellular polystyrene filling 60-80% of the compartments. The belt material can be nylon and the locks plastic material.

Cellular polystyrene has been treated with a flame retardant treatment. There are eight compartments and the volume of granular material can vary from 10 to 20 l depending on the load capacity of the vest.
