It is a Cape on the seat of the vehicle and consists of a base, the front part is made with a perforated floor, and a cavity with vozduhoprovodyaschih channels connected corrugated duct unit is m air injection, placed under the seat of the vehicle or on the rear side of the seat back of the vehicle with the ability to connect to the vehicle electric circuit for forced circulation of air between the pelvic-dorsal region of the body and the seat of the car. The technical result is to simplify the design (U.S. Patent No. 2297342).

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

The purpose of the utility model is to provide an optimal level of comfort activity vehicle drivers.

The aim is achieved in that the device is presented in the form of a module to cover the seats of the vehicle containing the electric heating elements associated with the power source and it is made in the form of a liner in the case of elastic material, the upper part of the case is made of mixed fabrics, or fabrics made of synthetic fibers with cells not less than 5 mm; lateral and bottom of the case is made of air - and water-resistant fabric; insert made of synthetic material (for example, from the isolon), on upper side it is executed in parallel hosted fin of rectangular profile, the space between the ribs, the base and the covering cloth cover form a channel, one end of each channel is associated with the inlet and the other outlet to the lecturers; the intake manifold through the pipe with the inlet valve associated with the ventilation system of the body of the vehicle, the exhaust manifold through the exhaust valve associated with the atmosphere; in the channels between the ribs on the basis of the elements of the electric heating, the channels are placed temperature sensors, humidity, speed of air movement associated with the registration unit connected through the signal amplifier with the computing unit, which is connected with the control unit, the outputs of which are connected with the Executive bodies - intake, exhaust valves, electric heating elements, a regular system of heating and ventilation systems of the body.

Figure 1 presents the scheme of the device in section;

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

figure 3 presents the electrical circuit of the device.

The device is a module for covering the seat of the vehicle containing the electric heating elements (1)connected with the power source (2), and it is made in the form of a liner (3) in case (4) of elastic material, the upper part of the cover (5) is made of mixed fabrics, or fabrics made of synthetic fibers with cells not less than 5 mm; lateral and lower part of the cover (6) is made of air - and water-resistant fabric; insert (3) made of synthetic material (for example, sisalana), on the upper side its made placed parallel ribs (7) rectangular profile, the space between the fins and the base (8) and cover with a cloth cover (5) form the channels (9), one end of each channel is associated with the inlet (10), the other with the outlet (11) of the reservoir, the inlet manifold through the pipe with the inlet valve (12) is connected with the ventilation system of the body of the vehicle, exhaust manifold (11) through the outlet (13) of the valve is connected with the atmosphere; in the channels (9) between the ribs (7) the base (8) posted by electric heating elements (1), channels (9) are placed sensors (14) temperature, humidity, speed of air movement associated with the registration unit (15)connected through a signal amplifier (16) with the computing unit (17), which is connected with a control unit (18), the outputs of which are connected with the Executive bodies of the intake (12)and exhaust (13) valves, electric heating elements (1), regular system of heating and ventilation systems of the body, while the sensors (14), temperature, humidity, speed of air movement, the registration unit (15), a signal amplifier (16), computer unit (17), the control unit (18), an inlet (12)and exhaust (13) valves, and electric heating elements (1)connected with a power source (2).

The device operates as follows.

The proposed modules, connected to each other, provide p is the covering surface of the seat and the backrest of the driver, seat passengers.

The presence of channels (9)are formed in parallel placed ribs (7), (8), cloth covering the upper part of the cover (5) provides air circulation in the channels and removal of endogenous heat from the body surface in contact with the device. Sensors of temperature, humidity, rate of air movement in the channels (14) (figure 3) send a signal about the hygienic condition of the air in the channels (9) in the recording unit (15), where the signal enters the block signal amplification (16) and through computer unit (17) is fed to the control unit (18). Commands from the control unit (18) come on Executive bodies - the inlet valve (12), through which the pipe connects the intake manifold module (10) with the standard ventilation system and heating the body of the car. Received in the channels (9) fills the air exhaust manifold (11), and the excess of it is excreted through the exhaust valve (13). At low temperatures include electric heating elements (1).

Permanent connection of the Supervisory 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 repairs. Case (4), hosts the liner (3), provides the possibility of conducting R the bot under the car in bad weather, since the side and bottom of the case (6) is made of air - and water-resistant fabric. Case (4) is removable and can easily be washed and sanitized.

Depending on climate and geographical conditions, the drivers of terrestrial mobile technology in the process of professional activity may be exposed to both high and low temperatures inside the inhabited offices (cubicles) and outside of the object when carrying out any repair work. Especially often excessive cooling of the surface of the lower back and buttocks while driving techniques in difficult road and weather conditions, when the driver, experiencing high emotional stress, intense sweating and sweat due to the lack of effective ventilation in the area of the seat and the chair back strongly hydrates clothes. This leads to a significant increase in the heat transfer and cooling of these areas of the body. If optimal climatic conditions, the temperature of the skin in the lumbar region and buttocks is within 33-34C, then cooling its value can decrease by more than 5C, and in supraoptimal microclimatic conditions can be achieved at ambient temperature. Such a significant temperature differences and are the leading cause of acute exacerbation of chronic inflammatory diseases. Most arianny the temperature gradient between the front and rear surface of the body can occur when drivers repairs lying on the cold (snow, concrete, raw land, and others) or heated surfaces (asphalt, sand in the summer).

The removable module of the device to cover the seats of the vehicle containing the electric heating elements associated with the power source, characterized in that it is made in the form of a liner in the case of elastic material, the upper part of the case is made of mixed fabrics, or fabrics made of synthetic fibers with cells not less than 5 mm; lateral and bottom of the case is made of air - and water-resistant fabric; insert made of synthetic material (for example of the isolon), on upper side it is executed in parallel hosted fin of rectangular profile, the space between the ribs, the base and cover with a cloth cover to form channels, one from the ends of each channel is associated with the inlet, the other with the exhaust manifold; intake manifold through the pipe with the inlet valve associated with the ventilation system of the body of the vehicle, the exhaust manifold through the exhaust valve associated with the atmosphere; in the channels between the ribs on the basis of the elements of the electric heating, the channels are placed temperature sensors, humidity, speed of air movement associated with the registration unit connected through the signal amplifier with the computing unit, which is connected with the control unit, outputs the cat who was associated with the Executive bodies intake, exhaust valves, electric heating elements, a regular system of heating and ventilation systems of the body.
