    This invention relates to personal respiratory protection. The aim of the invention is to provide a landing that does not press on the body, as well as an extremely close to the body location of the center of gravity of the total load while reducing weight, facilitating putting on and taking off an insulating breathing apparatus and improving its transportation. In the device for wearing insulating breathing devices equipped with one or two compressed air cylinders with a reducer, the dorsal frame is made monolithic and is formed by two intersecting vertical I and horizontal 2 parts, equipped in various degrees with lowered profiles fitted to these parts with stabilizing profiles 3, 4 The vertical portion 1 of the framework is formed from a straight or slightly curved middle portion. The lower end in the form of a pillar II is bent to the other side opposite to the upper end. The horizontal part 2 of the frame is located at the arcuate transition of the middle part. 1 hp f-ly, 2 ill. so you

    The invention relates to individual respiratory protection and relates to a device for wearing insulating breathing devices equipped with one or two high-pressure compressed air cylinders, the contents of which become suitable for breathing through the gearbox and dosed depending on respiration. through the lung machine. /
    Insulating breathing devices are designed to be worn on the back. Their operation is always associated with work of the highest to medium degree of severity, carried out in order to eliminate accidents or rescue, where toxic fumes, gases, vapors and dust form or where oxygen deficiency makes the surrounding atmosphere unsuitable for breathing. people.
    An insulating breathing apparatus is known in which the device for wearing comprises a dorsal framework made monolithic, fastening devices of components on the frame and fastening belts to the human body. The upper end of the dorsal carcass is made in the form of a handle for carrying and is bent toward the person carrying the device (description of the invention to US Patent No. 3,957,183, Cl. 224-5, 1976).
    The shape of the support plate, although well adapted to the body, does not correspond to the average growth rates and the average posture of adults. male.
    The purpose of the invention is to provide a fit that is not pressing on the body, as well as an extremely close position of the center of gravity of the total load while simultaneously reducing the weight. In addition, it is easier to put on and take off an insulating breathing device, as well as to improve its transportation.
    The invention is based on the task of developing a dorsal frame adapted for wearing insulating breathing devices, the back of which have an optimal vertical and optimal horizontal curvature and meet the requirements set for it even with heavy work.

    In accordance with the invention, this task is solved by the fact that the dorsal framework is formed by two intersecting vertical and horizontal parts 1, 2, equipped in varying degrees, lowered, fitted to parts 1 and 2 of the frame, with stabilizing profiles 3, 4, vertical part 1 the frame is formed from a straight or slightly curved middle part 5, the upper end
    6 and bent to the other, opposite upper end 6 side of the lower end 7, horizontal part
    2 frame is located on the arcuate transition of the middle part 5. The lower end of the vertical part of the frame can be designed as a lower support.
    Figure 1 shows the dorsal framework; figure 2 - the planned position of the compressed air cylinder, side view.
    The device contains a monolithic back frame of two intersecting parts, vertical 1 and horizontal 2, which are provided with stabilizing profiles 3, 4, lowered to varying degrees, fitted to parts 1, 2 of the frame; on the part of the frame it is formed from a straight or slightly curved middle part 5, upper end 6 and from — bent to another opposite to the upper end 6 side of the lower end 7. The horizontal part 2 of the frame is located on the arcuate junction of the middle part 5.
    Both ends 6, 7 are approximately at the same angle to the middle part 5. Available at the lower end
    7, the transition of the arcuate shape, which borders on the middle part 5, also defines the contiguous area for the paranasal zone of the body. At this point is the horizontal part of the frame, which, in conjunction with the lower positioned stabilizing profile 3 of part 1 of the frame, provides an ideal position on the back. Thus, not only the vertical part 1 has a shape perfectly adapted to the spine of the wearing apparatus and the pressure-relieving shape, but also the horizontal part
    2 frames.
    The upper end b of part 1 of the frame has the shape of an octagon, odia
    the side 8 of which is made concave, and each of its two, bordering the middle part 5 of the sides, is provided with a stabilizing rib 9. In addition, the end 6 is designed as a carrying handle 10. The lower end 7 is designed preferably as a lower support 11 and prevents arining of the cylinders when removing the breathing apparatus.
    The back frame is preferably made of relatively thin aluminum sheet with a plastic coating and is equipped with fasteners. methods .12, respectively, .dl parts of the device and under the fastening straps to the human body.
    These auxiliary fasteners for compressed air cylinders, eliminating the need for additional fasteners, lead to a reduction in weight and allow extremely close mounting of the cylinders and gearbox directly on the back frame. This measure was able to reduce the distance between the center of gravity of the apparatus and the line passing through the center of gravity of the person wearing the apparatus by almost 7% compared with previous designs.
    In the device, compressed air cylinders with a gearbox are located extremely close to the dorsal frame. The cross-shaped design of the dorsal framework and its special fit to the back thereby prevents unpleasant pressure, eliminating the need for a soft backing. This is exclusive

    between the thoracic and lumbar vertebrae, and between the lumbar vertebrae and the coccyx. The back frame does not create a load on the blades and, when working with the hands, ensure the freedom of movement of the blades.
    Shortening the distance to the load with a body weight of about 17.5 kg leads to a noticeable improvement in comfort, which corresponds to a decrease in weight by about 1.5 kgf.
