2. The waistcoat according to p,}, about tl and h ayusch and the fact that on the inner sides of the back half of the back in their lower parts there are pockets, in which heaters are placed,

3. The vest according to claim. 1, so that the heaters are made of chemicals.

4. The vest according to claim 1, distinguished from and with R in that the vanes and halves of the backs of the life jacket are made of paired reinforced slots for the passage of the said belts through them.

This invention relates to means of rescuing a person in water, namely to life jackets. A lifejacket is known, which is filled with an elastic porous filler, with two (upper and lower) belts with fasteners, shelves, and a back completely separated by a human back divided by a longitudinal section of two halves connected in the upper rigid part | However, the well-known vacation vest constrains movement sport shift, has insufficient positive buoyancy, does not provide sufficient thermal protection for the human body. The purpose of the invention is to increase the thermal protection area of the human body and increase the reliability of the vest while maintaining the satisfactory performance of the vest at various and different positions of the athlete's body when operating the sailing vessel. To do this, in a life vest equipped with an elastic porous filler, two upper and lower belts with fastening elements, shelves and a back completely separated by a longitudinal slit in the upper half of the halves 5 of the shelf 5 in the upper hard part of the halves of 1 / 4 to 1/6 of its length, while in the nile & this part of x shelves at a distance of 1/6 to 1/3 of their length from the edges in the porous elastic filler there are grooves across their entire width with a depth equal to half the thickness lnitel, and on the sides. the vest from the bottom to the grooves are made two notches into which the lower belt is missed, which is installed only on the backs of the halves. On the inner sides of the backrest halves placed heaters made chemical. In the shelves and backs, paired reinforced slots for the passage of the said belts through them are made. FIG. 1 shows a general view of the vest in front; in fig. 2 - the same rear view; in fig. 3 - the same side view; in fig. 4 - view of the loops; in fig. 5 - the same, with another embodiment of the groove; in fig. 6 one of the positions of the athlete in the vest when driving a sail. A lifejacket is formed by shelves 1, halves of backs 2, interconnected in the upper neck, formed by a longitudinal incision 3. The shelves are shorter than the back by 1/4. up to 1/6 of its length. Between ;;:;, at the cloths, 4 shelves and back halves there is a porous elastic nylon 5z providing positive buoyancy of the vest, and the shelves filler is chosen more in thickness (approximately twice the backrest length in order to make the person turn over in the water face up. Waistcoat vest made shorter than the backs. In the lower part of the shelves up to 1/3 of their length from 1/3 of their length from the edges along their entire width in a porous elastic filler. The grooves 6 are made with a depth equal to half the thickness of the filler. the depth of the grooves is adjusted so that it allows the lower part of the shelves to be bent freely. The shape of the groove in the section can be different: rectangular, semi-circular, triangular, trapezoidal. On the sides of the vest, two notches 7 are located below the groove, which separate the lower the contour of the vest and the lower part of the shelves during the movements of the athlete rise and bend along the groove line. The cutouts are made in the form of a triangle with rounded corners, but can also be a straight cut. On the inside of the backs of the backs in the lower elongated part in the area along the human border are pockets 8 with chemical heaters, made of flexible elastic fabric and attached on three sides and the inner panel of the back halves with the free side up. Mana can be removable. In the outer panel of the vest, paired slots 9 are made on the inner side, which are closed by a reinforcement 10 made of a flexible material and attached to the canvas of the vest. Between the reinforcement and the strip of the P-sheet, bounded by the slits, an additional reinforcement 12 of a more durable flexible material is inserted ... in the form of a bvalan tube, on the one hand, the oval tube is attached to the reinforcement glued to the panel and on the other side with glue or firmware. the sides — to the strip of the web “searching, formed by paired slots; the lengths of these slots are chosen taking into account the passage in them of a belt and is not less than its width, and their width not less than the width of the belt is determined to be minimal and Loads in the design .Can be increased. To attach the vest to the body, two belts are used, one of which the top 13 runs at chest level, the other bottom 14 along the line of the waistcoat. The belts have locks 15 and buckle 6 for adjusting their length, and the upper belt is inserted into the loops of the shelves and back halves, and the lower belt passes only in the loops of the back halves and passes through the waistcoats through the side openings so that they can be lifted freely. . Before the start of operation, the vest of the upper and lower belts are adjusted in length, depending on the anthropometric data of the person. When using a vest in a cold frame, pockets located in the lower part of the back halves are placed in the pockets, for example, chemical heaters. When controlling the ships under sail, the athlete takes different positions, while the cut on the back of the vest does not constrain movements (the athlete turns to the left and to the right I, because the edges of the cut can freely fit or diverge. When the athlete tilts forward forwards, the lower part of the shelves the groove lines flex and rise freely, without flexing the legs. With the athlete's great dynamism, the belt transfers its load to the edge of the flexible tube, which reduces the force transmitted to the edge of the y1; Into the water, the athlete at the expense of filling the shelves and back halves is supported on the water. Thus, the life jacket is not constrained by the movements of the athlete, provides reliable warm protection of the human body.
