System of additional safety (SRS)

In this section the general provisions, functioning of system SRS concerning principles are considered only. The detailed description of its components is resulted in the Head the Onboard electric equipment.

Have no firm or sharp subjects between the body and safety pillows, do not transport firm or sharp subjects in a lap and do not smoke a tube at driving since it can lead to reception of serious traumas at failure. For the purpose of prevention of risk of unapproved operation of pillows of safety try not to press a hand to the locations of pillows and their modules. The locations of pillows of safety are noted by inscriptions «AIRBAG».

Into number of devices and components of system of additional safety (SRS) enter:

  • Two forward and two lateral pillows of safety. The module of a forward driver's pillow of safety is placed in a steering wheel nave; the pillow of safety of the forward passenger is placed in a special cavity in the right part of the panel of devices of the car. Lateral pillows of safety are placed in outer sides of backs of forward seats;
  • The gauges of the directed overloads working at strong front or lateral blow;
  • Electronic system of self-diagnostics which at the included ignition provides constant testing of gauges of overloads, the management block, газогенераторов pillows, пиропатронов emergency натяжителей seat belts and connecting electroconducting of corresponding chains;
  • Automatic emergency натяжители the seat belts, built in in regular натяжители seat belts of forward seats;
  • The control lamp SRS which has been built in in a combination of devices;
  • The spare independent power supply intended for duplication of the basic power supply system in case of its exit out of operation during collision.

Principle of functioning of pillows of safety

At weak face-to-face and lateral collisions, and also at overturning of the car of a pillow of safety should not to work.

Gauges of the directed overloads react to excess of some limiting value which can arise at strong front or lateral collision. On a signal of gauges the management block includes газогенераторы safety pillows, causing their instant filling.

During collision the seat belt keeps from displacement the bottom part of a trunk sitting. Forward pillows of safety help to prevent травмирование the driver and the forward passenger as a result of blow by their head and a thorax about a steering wheel/panel of devices or heading about racks of a body/glass of doors.

Both forward pillows of safety work simultaneously, 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 gauges. In this case seat belts provide reliable enough protection of the driver and the forward passenger while the effect from operation of a pillow of safety 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 controls the car.

Full duration of process from the moment of giving of a signal before release of gas from pillows occupies with gauges 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 a clap газогенераторов at filling of pillows.

After operation of pillows of safety the volume of salon of the car looks slightly filled with smoke because of a suspension тонкодисперсного a powder by which the combined covers of pillows are usually poured. People with disease of respiratory organs can feel certain discomfort from the gaseous products containing in air allocated gas generatorми of pillows.

Control lamp SRS

The control lamp (К/Л) SRS is built in in a combination of devices of the car (Razdel Kombinitsija of devices, measuring instruments, control lamps and indicators see).

At inclusion of ignition К/Л lights up approximately for 6 seconds and then dies away, confirming serviceability of functioning of all knots of system SRS.

If the lamp is not switched off, does not die away, and also at any operation К/Л during any other moment the owner of the car should address at the first possibility to experts HUNDRED since at the signs listed above system SRS can refuse during car failure. If К/Л does not die away, it specifies in malfunction of forward pillows of safety; if К/Л starts to blink, lateral pillows of safety and-or emergency натяжители seat belts are faulty.

Seat belts with automatic emergency натяжителями

Emergency automatic натяжителями returnable devices of seat belts of forward seats are equipped. Натяжители 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 much degree raising degree of protection of the driver and the forward passenger.

Натяжитель it is built in in assemblage of the returnable mechanism of a belt. The using order such seat belts is similar to an using order the usual belts equipped with inertial returnable devices. The operation mechanism натяжителя is absolutely transparent for the user and does not demand from the last any additional skills and knowledge.

Activation натяжителей occurs only at considerable face-to-face overloads. Operation of modules is accompanied by a loud clap and small emission of a smoke.

Allocated at operation натяжителей the smoke is safe for health of the person, however at direct inhalation can cause irritation of mucous membranes.

As well as in case of safety pillows, modules emergency натяжителей are calculated on unitary operation and after that are subject to replacement in gathering with belts, - address on HUNDRED.
