The disadvantage of this device is its technical complexity and high cost.

A device is known which relates to car seats with forced ventilation. It is a cape on a car seat and consists of a base, a front part made with a perforated coating, and a cavity with air ducts connected by a corrugated duct to an air discharge unit located under the car seat or on the back of the back of the car seat with the possibility of connecting to the power supply car for forced air circulation between the pelvic-spinal region of the human body and the car seat. The technical result is a simplification of the design (US Patent No. 2297342).

A disadvantage of the known devices is the inability to optimize the thermal regime of the drivers of transport equipment.

The purpose of the utility model is to provide an optimal level of comfort for drivers of vehicles.

Figure 1 presents a diagram of the device in section;

figure 2 presents a diagram of the device, a top view;

figure 3 presents the circuit diagram of the device.

The device is a module for covering vehicle seats containing electric heating elements (1) associated with a power source (2), moreover, it is made in the form of an insert (3) in a cover (4) from an elastic material, the upper part of the cover (5) is made from mixed fabrics or fabrics of artificial fibers with cells of at least 5 mm; the side and lower parts of the cover (6) are made of air- and moisture-proof fabric; the insert (3) is made of synthetic material (for example, from isolon), on its upper side there are parallel-mounted ribs (7) of a rectangular profile, the spaces between the ribs, the base (8) and the covering fabric of the cover (5) form channels (9), one of the ends of each channel is connected to the inlet (10), the other to the outlet (11) collectors; the intake manifold through the pipe with the intake valve (12) is connected to the ventilation system of the vehicle body, the exhaust manifold (11) through the exhaust (13) valve is connected to the atmosphere; in the channels (9) between the ribs (7) on the base (8) there are elements of electric heating (1), in the channels (9) there are sensors (14) of temperature, humidity, air velocity associated with the registration unit (15) connected through a signal amplifier (16) with a computing unit (17), which is connected to a control unit (18), the outputs of which are connected to the executive bodies - inlet (12), exhaust (13) valves, electric heating elements (1), standard heating and ventilation system body, with sensors (14), temperature, humidity, air velocity ear, registration unit (15), signal amplifier (16), computing unit (17), control unit (18), inlet (12), outlet (13) valves, as well as electric heating elements (1), are connected to a power source ( 2).

The device operates as follows.

The proposed modules, connected to each other, provide coverage of the surface of the seat and backrest of the driver's seat, passenger seats.

The presence of channels (9) formed by parallelly placed ribs (7), a base (8) covering the fabric of the upper part of the cover (5) ensures air circulation in the channels and the removal of endogenous heat from the surface of the human body in contact with the device. Sensors of temperature, humidity, air velocity in the channels (14) (Fig. 3) send a signal about the hygienic state of the air in the channels (9) to the registration unit (15), from where the signal enters the signal amplification unit (16) and through the computing unit (17) enters the control unit (18). The commands from the control unit (18) are sent to the executive bodies - the intake valve (12), which through the pipe connects the intake manifold of the module (10) with the standard ventilation and heating system of the car body. The air entering the channels (9) fills the exhaust manifold (11), and its excess is discharged through the exhaust valve (13). At low temperatures, electric heating elements are switched on (1).

The constant connection of the controlling and executive bodies of the device with the power source (2) ensures reliable operation of the system.

If necessary, the modules can be interconnected in the form of a mat-litter for repair work. The cover (4), in which the insert (3) is placed, provides the ability to work under the car in bad weather, as the side and lower parts of the cover (6) are made of air- and moisture-proof fabric. Case (4) - removable and easy to wash and sanitize.

Depending on climatic and geographical conditions, drivers of ground-based mobile equipment in the process of professional activity may be exposed to both high and low temperatures inside inhabited departments (cabins) and outside the facility during any repair work. Especially often there is excessive cooling of the surface of the lower back and buttocks when driving in difficult road and climatic conditions, when the driver, experiencing high psycho-emotional stress, sweats intensively and sweat due to the lack of effective ventilation in the area of the seat and back of the chair greatly moisturizes clothes. This leads to a significant increase in heat transfer and cooling of these parts of the body. If under optimal climatic conditions the skin temperature in the lumbar region and buttocks is in the range of 33-34 ° С, then with cooling its values can decrease by more than 5 ° С, and in supraoptimal microclimatic conditions they can reach the ambient temperature. Such significant temperature differences are the leading cause of acute and exacerbation of chronic inflammatory diseases. The most pronounced temperature gradient between the front and rear surfaces of the body can occur when drivers perform repair work lying on chilled (snow, concrete, damp earth, etc.) or heated surfaces (asphalt, sand in the summer).
