System of additional safety (SRS)
Enter number of devices and components of system of additional safety (SRS):
Principle of functioning of safety cushions
Sensors of the directed overloads react to excess of some extreme value which can arise at strong head-on or side crash. On a signal of sensors the control unit includes gas generators of safety cushions, causing their instant filling.
During collision the seat belt holds the lower part of the trunk sitting from shift. Forward safety cushions help to prevent traumatizing the driver and forward passenger as a result of blow by their head and a thorax about a steering wheel / dashboard or heading about bodies/glasses of doors are resistant.
Both forward safety cushions work at the same time, as well as both side pillows. However the probability of operation of only one of couple of pillows is not excluded, - it becomes possible when the size of the directed overloads which arose at collision was on the verge of the range of sensitivity of sensors. In this case seat belts provide rather reliable protection of the driver and forward passenger while the effect of operation of a safety cushion is minimum.
Right after operation and performance by pillows of the functions gas from them is produced that allows the driver to keep visibility and to manipulate freely all governing bodies of the car.
The full duration of process takes with sensors of overloads before production of gas from pillows no more tenth fraction of a second the moment of giving of a signal. Operation of modules happens so quickly that the human ear simply is not capable to apprehend cotton of gas generators when filling pillows.
After operation of safety cushions the volume of interior of the car looks slightly smoke-filled because of a suspension of fine powder which usually pours the put covers of pillows. People with a disease of respiratory organs can feel a certain discomfort from the gaseous products which are contained in air allocated by gas generators of pillows.
Control lamp of SRS
The Control Lamp (CL) of SRS is built in in a combination of devices of the car (see Kombinition's Section of devices, measuring instruments, control lamps and indicators).
At inclusion of ignition To/L lights up approximately for 6 seconds and then dies away, confirming serviceability of functioning of all knots of the SRS system.
If the lamp is not switched off, does not die away, and also at any operation To/L at any other moment follows the owner of the car at the first opportunity to address experts HUNDRED since at the listed above signs the SRS system can refuse during failure of the car. If To/L does not die away, it indicates malfunction of forward safety cushions; if To/L begins to blink, side safety cushions and/or emergency natyazhitel of seat belts are faulty.
Seat belts with automatic emergency natyazhitel
Emergency automatic natyazhitel equipped returnable devices of seat belts of front seats. Are put by Natyazhiteli in action at the strong frontal overloads arising at head-on collision and provide instant selection of a weak point of belts therefore tapes of the last densely cover a body sitting, in considerably degree increasing degree of protection of the driver and forward passenger.
Natyazhitel is built in in assembly of the returnable mechanism of a belt. The order of use of such seat belts is similar to an order of use of the usual belts equipped with inertial returnable devices. The mechanism of operation of a natyazhitel is absolutely transparent for the user and does not demand from the last any additional skills and knowledge.
Activation of natyazhitel happens only at considerable frontal overloads. Operation of modules is followed by loud cotton and small emission of smoke.
As well as in case of safety cushions, modules of emergency natyazhitel are calculated on single operation and after that are subject to replacement assembled with belts, - address on HUNDRED.
