Every year in the world, about 1.2 million people die in car accidents. Russia is in the first positions among European countries on the total number of deadly accidents. It is worth noting that the outcome of the accident does not least affect the technical properties of the vehicle. Therefore, car owners and automakers are puzzled by finding better protective devices and mechanisms. As numerous testing shows, the driver's airbag significantly reduces the risk of his death. Only imagine, with a frontal collision of cars, the driver is 20 - 25 percent more chances for survival, if its vehicle is equipped with airbags. Read more about this in the article.

Airbags where they are

Car airbags (international generally accepted name - Airbag) are intended to mitigate the drivers and passengers about the steering column, windows and elements of the body with a car accident.

They are used simultaneously with seat belts.

Modern passenger cars are distinguished by the presence of several airbags, which are located in various places of the vehicle salon. Depending on the location of the location, there are such types of "Aerbegs" - side, front, knee, head, central airbag.

Side airbags are designed to reduce the risk of injury to the pelvis, the abdominal cavity and the chest at an accident. Usually they are installed in the back of the front seating. Some cars suggest the installation of side airbags in the rear seats.

Front airbags are different - driver airbag and front passenger. As a rule, the front passenger is provided for the front passenger's front passenger. The driver's front airbag is located in the steering column, and the front passenger is in the right upper part of the front panel.

The knee airbags protect the leg and kneeling the driver from injuries. They are located under the steering column.

Head airbags, the people referred to as "curtains" of security, serve to protect the head during the lateral collision. They are, depending on the vehicle model, between the racks, in the back or front of the roof. The main task of these pillows is the protection of passengers of both the front and the rear row of the seats.

The central airbag is designed to reduce the severity of secondary damage to the passengers during the lateral collision. It is located in the central back of the rear seat back and in the armrest of the front row of the seats.

How to work airbags

Airbags are a bag of fine nylon or other materials, often divided by cameras. To prevent keeping, the pillow is moved by starch or talc, after which they are packaged in a small capsule.

It was originally obvious that the bag should be very quickly inflated, mostly less than fifty milliseconds. To perform this standard since the 70s of the twentieth century, the only means was a minor explosion, which leads to the release of non-toxic nitrogen filling the bag. The explosion is provided by a pyropatron, which consists of a number of chemical elements. There are also hybrid systems, the charge of solid fuels in which is a "plug" that closes the cylinder with compressed nitrogen.

In modern vehicles, electronics receives data from shock sensors and, if necessary, sends a signal to activate airbags. Sensors There are several, so electronics can determine which side there is a collision. Some progressive devices are capable not only to determine the force of impact, but also adjust the volume of gas and, accordingly, the size of the pillow, taking into account information about the mass of the passenger.

Security system, as indicated

In transport airbags are indicated by Airbag icons. These icons can be applied to special tissue tags or squeezed on plastic. As a rule, the knee, frontal, head and rear side "Aerbegi" are marked on plastic elements of the sheath, and the front side pillows mark on the side of the seats on the plastic tags.

Not recommended without turning off the battery Open or disassemble the lounge of the cabin near the airbags. An attempt to remove cushions under tension is able to lead to their triggering, which entails heavy injuries.

Knowledge of electronics, whether to understand the electronics when replacing airbags

Immediately it is worth saying that if you do not understand absolutely nothing in electronics, this event should not behave independently, since it will not work out to do with the usual unscrewing bolts and replacing the new element. The on-board computer has its own defined nuances. Therefore, if you decide to independently replace airbags, you should either have knowledge in the field of electronics, or should refer to specialists.

Driver airbag, how to replace it

First of all, you should disconnect the battery terminals. This should be done not only for security reasons, but in order to do not give an error when replacing the on-board computer. The airbag on the steering column (driver) is changing very simply. You should defam the central part, then disconnect the contacts and build a new pillow, then collect everything back.

Front passenger airbag, step-by-step replacement instructions

With the replacement of the passenger pillow, as a rule, there are difficulties, since most of them are hidden behind the torpedo and during the triggering is spoiled. In a variety of cars for replacing the pillow, you have to completely dismantle the torpedo.

1. The disassembly must be started from the steering wheel, since it is here that the most open details, latches and bolts are located.
   
2. Remove the cover of the steering column, after which we unscrew the airbag on the steering wheel, regardless of whether it worked.
3. Under it is a fastener bolt of the steering column. It must be removed by reloading the bolt.
4. After removing the steering wheel, we dismantle the bottom of the protection over the pedals, for which it is necessary to unscrew the snapshots and the bolts under the helm of the steering wheel.
5. After dismantling the protection, you can easily get to the center console and on-board computer.
   
6. To access the central console, you must pull out the radio and everything else that keeps on the front console.
7. Remove the torpedo.
8. We dismantle the cushion mechanism, after which we install a new and connect the wires.

On-board computer, how to solve the problems of the on-board computer, how to eliminate the error in memory of the airbag

To eliminate this error, you must either completely replace the on-board computer, or flash software. It is recommended to choose the last option, as it is worth it much cheaper, but the firmware is not able to give a 100% guarantee that the pillow will not work even when the strike is not.

How to flash on-board computer at home, general recommendations

If you decide to independently flash the on-board computer, for this you will need a laptop, good knowledge in the field of electronics, cord for connecting an on-board computer to a laptop and special software under the model and the brand of your vehicle.

We will not paint the firmware procedure itself, because for each vehicle model it is unique. The meaning of the firmware is based on replacing the software block. However, in new foreign cars it is desirable to replace the block, since the next time the airbag may not work at all.

If the firmware has passed successfully, boldly collect everything back. It is most difficult to flash the on-board computer in new cars, where it is fully responsible for managing the vehicle.

Professional advice and what the wrong software replacement can lead to

When firmware, do not rush to connect new airbags, since incorrect software replacement leads to new, and you will have to buy them again.
