The disadvantage of such solutions is the difficult implementation, especially when the lifejacket is made of two independent buoyancy chambers. Also, the disadvantages of some of the known solutions include non-compliance with the requirements and standards for rescue equipment used at sea.

Known aircraft-marine life jacket XF-35 (https://www.inflatablesintl.com/product/eastern-aero-marine-vests-xf-35-life-vest/), made of two independent buoyancy chambers with air filling and blowing tube. However, this solution cannot be attributed to analogues (to be a prototype) for the claimed utility model. Inflated buoyancy chambers do not fix a person's neck and head, and cannot provide a stable position face up in the water. The vest fixes the neck, but not the head, so the back of the head remains in a hanging position.

The closest to the claimed technical solution is an automatic inflatable life jacket Seacrewsader 275N (https://survitecgroup.com/survitecproducts/499/Seacrewsader275N), containing a protective cover, a double buoyancy chamber with an angle of inclination of the body, each chamber of the vest is equipped with two systems of gas filling and tubes blowing.

This solution has positive buoyancy and is designed for use in extreme conditions. However, inflatable buoyancy chambers are dependent, which reduces the level of safety. The design is fragile, insufficiently strong fixation of the head and neck in distress.

The claimed technical solution is free from these disadvantages.

The technical result of the utility model is to improve the ergonomic properties of the life jacket in terms of: increasing injury safety, namely, relieving stress from the neck of a person when the vest is in working order, ensuring the natural position of the head of a person in distress in the water; preventing water from entering the respiratory system and ensuring freedom of movement when using the vest.

For this, an inflatable life jacket containing a protective cover and U-shaped inflatable buoyancy chambers, which are equipped with automatic gas filling systems and inflation tubes, in accordance with the claimed technical solution, U-shaped inflatable buoyancy chambers are made independent, the upper chamber has a horizontal shift relative to the lower chambers away from the human body, the lower inflatable buoyancy chamber is a shift relative to the upper inflatable buoyancy chamber to the human body, the offset of the inflatable buoyancy chambers relative to each other is fixed using two crossed straps that are attached to the protective cover of the vest from the side of the lower chamber using pullers, and then, passing in a cross way through the upper chamber, they are also attached to the vest cover using pullers from the side of the upper chamber.

In addition, automatic gas filling systems and inflating tubes are located on the front of the vest.

FIG. 1 shows an inflatable life jacket in a protective cover (assembled).

Figs 2, 3 show the position of the inflatable buoyancy chambers relative to each other.

Figure 4 shows an inflatable life jacket in working condition (rear view).

Figure 5 shows a diagram of the fastening of crossed belts.

Figure 6 shows an assembly drawing.

Inflatable life jacket - a two-chamber life jacket (Fig. 1-6), in which the inflatable buoyancy chambers 1 and 2 are made independent, which allows not only to increase the height of the life jacket in working condition, thus preventing water from entering the respiratory organs, but and increase the chance of survival in case of damage to one of the cameras.

Buoyancy chambers 1 and 2 are made in the form of an inverted English letter "U" - the optimal shape of the clamp, which makes the lifejacket comfortable to wear in the assembled state; for this, the lifejacket has a protective cover 3 (Fig. 1).

In working condition, the inflatable buoyancy chambers 1 and 2 are located relative to each other in the following way: the upper inflatable buoyancy chamber 1 provides a girth in the head area, the lower inflatable buoyancy chamber 2 in the neck area, thus ensuring the ergonomics of the vest design, its injury safety (Fig. 2-4).

The design feature is that the upper inflatable buoyancy chamber 1 has a horizontal displacement relative to the lower inflatable buoyancy chamber 2 away from the human body, as shown in FIG. 2 and FIG. 3, which provides an ergonomic girth of the human head with the upper inflatable buoyancy chamber, and the shifted lower inflatable buoyancy chamber 2 towards the human body relative to the upper buoyancy chamber 1 provides a comfortable girth of a person's neck, which in general provides a comfortable and ergonomic position of the head part of the vest for the neck and head without hindering movement and ensuring ease of use, both on land and on water.

Thus, the inclination of the inflatable chambers (Fig. 2) is structurally set to the left of the vertical axis (F1 - the direction of the force action) and downward from the horizontal axis (F2 - the direction of the force action). This position of the buoyancy chambers 1 and 2 relative to each other is ensured by the fact that the shift is fixed by means of two crossed belts 4 (Fig. 3 and Fig. 5), which are attached using pullers to the protective cover of the vest 3 from the side of the lower inflatable buoyancy chamber 2 , and then, passing in a cross way through the upper inflatable buoyancy chamber 1, also, using pullers 5, are attached to the vest cover 3 from the side of the upper inflatable buoyancy chamber 1.

The optimal solution for an inflatable life jacket proposed in the utility model, when the gas filling system 6 and the inflation tube 7 of both inflatable buoyancy chambers are located on the front side of the vest, as shown in FIG. 6, which has much greater advantages in terms of operation and ergonomics.

An example of using an inflatable life jacket:

1. An inflatable life jacket in the assembled state, as shown in FIG. 1 is put on over the right shoulder, passing the hand through the shoulder girdle and the waist belt (the shoulder girdle and the waist belt are elements of the belt attachment system, which is a mandatory attribute of every lifejacket, the subject of patent claims under this application is not and is given only to represent an example of using the vest rescue inflatable). Next, the vest is put on the left shoulder and the belt buckle is fastened, fixing the vest on the human body. U-shaped inflatable buoyancy chambers, assembled in a protective cover, are a collar that goes around a person's neck and descends from the chest to the waist, leaving freedom on the back and not interfering with the movements of the arms and head.

2. If a person enters the water, the automatic gas filling system is activated within 5 seconds, the U-shaped inflatable buoyancy chambers 1 and 2 are inflated, while the protective cover of the vest 3 opens independently. Crossed belts 4 (Fig. 3 and Fig. 5) are tightened, and due to attachment to the protective cover of the vest from the side of the lower chamber using pullers, and then, passing in a cross way through the upper chamber, also to the vest cover using pullers with the sides of the upper chamber provide a horizontal shift of the upper inflatable chamber 1 relative to the lower inflatable chamber 2 away from the human body, and the lower inflatable buoyancy chamber 2 provides a shift relative to the upper inflatable buoyancy chamber 1 to the human body (Figs. 2-4). The human body rises to the surface of the water face up. At the same time, the ergonomics of the spine is observed, the neck and head are located comfortably, there are no restrictions on head and body movements. A person can not only lie comfortably on the surface of the water, but also look around, for example, for a collision with the wreckage of a ship or to assess his position relative to land, and also swim, thus, performing not only the passive role of the rescued, but also take active actions to saving your life.

3. In the case when it is required to additionally fill the chambers or increase their inflatable capacity, use the inflation tubes 7 of both inflatable buoyancy chambers located on the front side of the vest, as shown in FIG. 6. To do this, take the inflating tube of the lower inflatable buoyancy chamber 2 and press it to the mouth to inflate the chamber, similarly blowing the upper inflatable buoyancy chamber 1 is carried out.

4. The location of the gas filling systems of the 6 buoyancy chambers on the front side of the vest also helps to bring the vest into working condition in manual mode.

The content of the requirements for lifejackets is determined by their task.

When worn, the lifejacket must not interfere with circulation, be bulky, heavy or uncomfortable. The shape of the cameras and the protective cover ensure this requirement.

The lifejacket should not restrict visibility, audibility, freedom of breathing or movement when worn both on the shore and in the water, as well as during testing, ensuring sufficient comfort, including during rescue operations. The horizontal displacement of the cameras relative to each other and the solution to fix them with two crossed belts provide this requirement.

The lifejacket must guarantee the "face up" position of the person being rescued on the water; the combination of essential features of the utility model "as a whole" provides this requirement.

Thus, the implementation of the specified set of features of the utility model provides a technical result, which consists in improving the ergonomic properties of the claimed inflatable life jacket.
