The main task of the airbag is to slow down the person's movement as quickly as possible and not to let his blow on the machine's details. Despite the fact that its action seems uncomplicated, engineers are working on improvement at the present time. The airbag has a number of conditions. Without them, in case of an accident, it will not only not save your life and health, but on the contrary, it can worsen the situation.
Let's consider in detail how the airbag works
The principle of operation is based on three components: the pillow consists of nylon fabric, neatly packed into the steering wheel, torpedo, door and seat; A sensor that provides a signal for triggering; System, filling it with gas. Having received the collision signal, the sensor activates a system that mixes potassium nitrate and sodium azide. The resulting gas fills up the airbags. Just a moment they are in the most inflated condition, then they are blown off immediately so that the passenger can move. In addition, cars with a system such as an airbag for a pedestrian often met. It is under the hood, between it and the front windshield. When faced with a pedestrian, such a system significantly reduces the risk of serious injuries.
Danger of the system
Despite the fact that the purpose of the system is to protect human life, it can conceal a lot of dangers in itself. Often, we ourselves are to blame for the fact that the airbag did not work as it should. The speed with which it ejected reaches up to 300 kilometers per hour. The goal of engineers is now to reduce it, but you should try not to lose the effectiveness of the pillow itself. The seat belt at the time of its ejection slows the movement of the body during a collision. In this case, the airbag softens the impact, minimizing the risk of injuries that are life-threatening. But this is if you do not exceed the speed limit. It is necessary to know that car manufacturers, developing a security system, test it at a speed of about 60 kilometers per hour, while meeting all the requirements. Of course, when driving 160 km / h, it is better not to rely on pillows. If you ignore the belt, then the triggered system "shoots" at you with great force, and most likely, the consequences of such a strike will be deplorable. Do not try to outwit the system by fastening the strap behind you or by plugging the plugs into the locks. You play with fire, and at stake are your health and life. Now some cars are equipped with sensors that disable airbags if the belt is not fastened. But in this case the chance to get out of the road accident is minimal.
Unexpected situations
Sometimes it happens that the airbag works in situations where it is not necessary. For example, if at high speed the car hits the wheel in a deep hole. Or something heavy falls on the hood. And even when you "jump" through the rails, it can open. There are absolutely opposite situations when the airbag did not work. Most often this is either an industrial marriage, or a technical malfunction of the system. Very carefully it is necessary to concern to cars which have already visited an accident. You are not immune from getting into an auto in which you do not know how the pillow was repackaged. And in general, the guarantee that it is in place, no one will give you.
