8.3.12. Prednatyazhitel of seat belts (gas generator)
Work of a prednatyazhitel
At front blow under a certain corner in case of collision of the car the electric chain of management of a gas generator in the electronic SRS control unit which ignites a gas generator electrofuse becomes isolated.
Gas made by a gas generator вызывет a piston premeshcheniye in the case of an inlet collector of a prednatyazhitel (cylinder) which influences a ratchet (rack gear).
The ratchet brings into rotation a piston gear wheel, and a leading gear wheel – planetary gear wheels (planet gears).
At last, the cloth of a seat belt is involved (stretches) rotation of the inertial coil. Thus the prednatyazhitel of a seat belt promotes reduction of probability of receiving a trauma by the driver (or the forward passenger) by a tension of its seat belt. Possibility of moving of the driver (or the forward passenger) forward and his blow about a steering wheel or the dashboard is as a result prevented at car collision.
