System of additional safety (SRS)
Into number of devices and components of system of additional safety (SRS) enter:
Principle of functioning of safety cushions
Sensors of the directed overloads react to excess of some limiting value which can arise at strong head-on or lateral collision. On a signal of sensors the control unit includes gas generators of safety cushions, causing their instant filling.
During collision the seat belt holds from shift the lower part of a trunk sitting. Forward safety cushions help to prevent a travmirovaniye of the driver and the forward passenger as a result of blow their head and a thorax about steering the wheel/dashboard or heading about bodies/glasses of doors are resistant.
Both lobbies of a safety cushion work at the same time, no less than both lateral pillows. However the probability of operation only is not excluded by one of pair of pillows, is becomes possible when the size of the directed overloads which have arisen at collision was on the verge of a range of sensitivity of sensors. In this case seat belts provide rather reliable protection of the driver and the forward passenger while the effect from operation of a safety cushion will be minimum.
Right after operation and performance by pillows of the functions gas from them is issued that allows the driver to keep visibility and freely to manipulate all governing bodies the car.
Full duration of process from the moment of giving of a signal before production of gas from pillows borrows with sensors of overloads no more the tenth fraction of a second. Operation of modules occurs 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 salon of the car looks slightly filled with smoke because of a suspension of a tonkodispersny powder by which the combined covers of pillows are usually poured. People with a disease of respiratory organs can feel a certain discomfort from the gaseous products containing in air allocated by gas generators of pillows.
Control lamp of SRS
The control lamp (To/l) SRS is built in in a combination of devices of the car (see. Kombinitsy's section of devices, measuring instruments, control lamps and indicators).
At ignition inclusion To/l lights up approximately for 6 seconds and then dies away, confirming serviceability of functioning of all knots of SRS system.
If the lamp is not switched off, does not die away, and also at any operation To/l during any other moment the owner of the car should address at the first possibility to experts HUNDRED since at the signs listed above the SRS system can refuse during car failure. If To/l does not die away, it indicates malfunction of forward safety cushions; if To/l starts to blink, lateral 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 forward seats. By Natyazhiteli are put in action at the strong face-to-face overloads arising at a head-on collision, and provide instant sample of a weak point of belts therefore tapes of the last densely cover a body sitting, in considerably degree raising extent of protection of the driver and the forward passenger.
Natyazhitel is built in in assembly of the returnable mechanism of a belt. The order of using such seat belts is similar to an order of using 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 occurs only at considerable face-to-face overloads. Operation of modules is accompanied by loud cotton and small emission of a 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.
