The system of airbags and seat belt pretensioners
The airbag is integrated into the steering wheel. It fills the air as a result of the explosive process with 1/30. Even after 1/10, she begins to deflate due to being in her holes. The front passenger airbag volume of 170 liters is filled with a gas generator and, if necessary, be disclosed only if the passenger seat is occupied. Under the front passenger airbag has provided a small glove box. System response pretensioners can be diagnosed. Seat belt pretensioners are on the roller mechanism of the front seat. Resulting device pushes up the piston, which is connected via a metal wire with the axis of the roller belt mechanism. Thus, the belt is tightened on the body with the force of 1200 N, preventing the weakening of the belt in a crash. Airbags and seat belt pretensioners are activated gas in Mercedes formed from a solid explosive. If the electronic device operation (before the gear lever) recognizes the delay of a vehicle identical to blow at a speed of 15-18 km / h on a solid obstacle in the pyro cartridge supplied with current, and under the action of an explosive gas is formed. The system is self-powered by a capacitor that supplies current to the pyro cartridge gas generators, even when the battery fails on impact.
