System of additional safety (SRS)
Scheme of an arrangement of the typical SRS components
Enter number of the devices and components forming system of additional safety (SRS):
a) Two forward (frontal) safety cushions - a standard complete set. The module of a driver's safety cushion is placed in a nave of a steering wheel. The safety cushion of the forward passenger is placed in a special cavity in the right part of the dashboard of the car. The locations of both pillows are marked with precautionary inscriptions of "SRS AIRBAG";
b) Two lateral safety cushions of forward seats - an additional complete set. Modules of lateral safety cushions are built in in external lateral parts of backs of seats;
c) The sensors of the directed overloads working at strong front/lateral blow;
d) Electronic system of self-diagnostics which at the included ignition provides continuous testing of sensors of overloads, the control unit, gas generators of pillows and a connecting electrical wiring corresponding to a chain;
e) Devices of an automatic emergency tension of seat belts of forward seats - a standard complete set;
f) The control lamp of refusals of SRS which is built in in the dashboard;
g) The spare independent power supply intended for duplication of the main power supply system in case of its exit out of operation at collision of the car.
In an instrument guard of the car the special control lamp of SRS (see the Section Dashboard - the general information) intended for the warning of the driver of the refusals revealed by system of self-diagnostics in system of additional safety is built in. Depending on a car complete set operation of a control lamp testifies to possible malfunctions of modules of frontal/lateral safety cushions or devices of an automatic emergency tension of seat belts.
Principle of functioning of frontal safety cushions
Do not transport children of younger age on a forward seat of the car equipped with a passenger safety cushion at all! Told treats as well installation on a forward seat of a special children's seat.
At weak collisions and capsizing of the car frontal safety cushions should not work.
Sensors of the directed overloads react to excess of some limit value which can arise at a strong head-on 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 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 their head and a thorax about a steering wheel / dashboard.
As signals on operation of both safety cushions arrive from the same sensors, both pillows work at the same time. However the probability of initiation of only one of pillows is not excluded. Such 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 from operation of a safety cushion is 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 of the car.
The full duration of process from the moment of giving of a signal occupies with sensors of overloads before production of gas from pillows fractions of a second. Operation of pillows happens so quickly that the human ear simply is not capable to apprehend cotton of gas generators when filling pillows.
After a road accident at which there was an operation of safety cushions, the volume of salon of the car looks slightly filled with smoke. Actually it is a suspension of fine powder by which covers of pillows in the put state 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.
Principle of functioning of lateral safety cushions
On some models as an additional complete set lateral safety cushions of the driver and forward passenger can be established. Modules of pillows are built in in external end faces of backs of forward seats. The locations of both lateral pillows are marked with inscriptions of "SIDE AIRBAG".
At strong lateral blow sensors of the directed overloads fix excess by the arising loadings of some threshold value and give out information signal on the control unit which develops command for operations of a gas generator of the corresponding lateral safety cushion. Thus, if the blow had from a passenger seat, the passenger lateral pillow will work even in the absence of the passenger on a forward seat.
For ensuring the greatest efficiency of protection which is provided by safety cushions, the driver and the passenger sitting on a forward seat have to sit directly and to be fastened by seat belts.
Order of functioning of a control lamp of refusals of SRS
At ignition inclusion (the ignition key will turn in the situation "ON") the control lamp lights up for a short time, then at once dies away that confirms about serviceability of functioning of all knots of system.
At any operation of a control lamp at any other moment follows the owner of the car at the first opportunity to ask for the help specialists of car repair shop of the Subaru company. The following is among such situations:
a) The control lamp does not join at turn of the ignition key in the situation ON;
b) The control lamp continues to burn after implementation of start of the engine;
c) The control lamp is activated and burns in the constant or flashing mode during the movement of the car.
In the presence of the listed above malfunction signs the additional security system can refuse at failure of the car.
Negligence to signals of a control lamp of SRS can lead to the most serious consequences at refusal of safety cushions during a road accident!
Seat belts with automatic emergency natyazhitel
See also Section System of Additional Safety (SRS) - the device and the principle of functioning in the Head Onboard electric equipment.
Are put by Natyazhiteli in action at the strong frontal overloads arising at a 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 raising extent of protection of the driver and forward passenger.
Natyazhitel (And) 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 smoking.
The smoke which is allocated at operation of natyazhitel is safe for health of the person, however at direct inhalation can cause irritation of mucous membranes.
It is necessary to notice that refusals of operation of natyazhitel at a head-on collision in most cases are explained not by malfunction of system, and that the overloads arising at blow do not reach threshold value at which activation of modules is made.
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 firm car repair shops of the Subaru company. In the same place all claims concerning refusals of the SRS components are accepted.
Maintenance of the SRS elements
Safety cushions and devices of an automatic emergency tension of seat belts, practically do not need regular checks and maintenance. However the owner of the vehicle equipped as appropriate has to mean the next moments:
a) After operation of safety cushions they are subject to obligatory replacement together with the control unit of system. Do not try to dismantle the fulfilled pillows independently. These operations have to be carried out only in the conditions of a workshop of car service;
b) If operation of a control lamp of SRS indicates existence of refusal in system, it is necessary to address immediately on the nearest car repair shop of the Subaru company where full diagnostics and necessary recovery repair of system will be made. Otherwise safety cushions can not work at a road accident and not execute the protective function;
c) Only specially trained personnel is allowed to works with knots of an additional security system. It is forbidden to dismantle independently from the car of a safety cushion and emergency natyazhitel of seat belts. In case of refusal SRS or after emergency operation of safety cushions and natyazhitel of seat belts it is necessary to address on car repair shop of the Subaru company for carrying out repair or replacement of knots of system;
d) Do not open modules and do not change an electrical wiring of systems of safety cushions and devices of an automatic emergency tension of seat belts, - such intervention can lead to involuntary operation of pillows and natyazhitel and be the reason of traumatizing the performer or the people who are nearby;
e) Do not make replacement of forward seats without receiving preliminary consultation at car repair shop of the Subaru company. Inaccurate or incorrect performance of replacement or removal of covers can lead to refusal of operation of lateral safety cushions in case of a road accident.
By transfer of the car to other person it is necessary to inform without fail the last on all established SRS elements with the indication of the corresponding points of the instruction on rules of use of the car.
On all equipped SRS models in locations of active elements systems are installed the special warning plates.
