The mechanism of a natyazhitel of a seat belt of a front seat - the general information

On all models equipped with safety cushions also installation of automatic natyazhitel of seat belts of front seats is provided. At head-on collision the natyazhitel instantly chooses all weak point of a belt taking place, to a limit limiting freedom of movement of the driver / the forward passenger and reducing, thereby to a minimum risk of receiving injuries by them. The mechanism of a natyazhitel is fixed directly on an inertial drum of the returnable device of a seat belt.

Natyazhitel is equipped with the inertial mechanism working at excess by frontal overloads of a certain value. More light blows do not lead to operation of the device.

At turning on of the mechanism there is an ignition of the fuel device placed inside. At the same time the assembly piston sharply moves forward, choosing a weak point of a belt which at the same time is taken up on an inertial drum of the returnable device. Energy of the natyazhitel of explosion occurring in the cylinder guarantees the reliable passenger of fixing by a belt
safety. After operation a natyazhitel it is irreversible it is blocked and is not subject to reuse.

When working on service of the seat belts of front seats equipped with natyazhitel it is necessary to observe some special precautionary measures:

If you incidentally dropped a natyazhitel, he has to be replaced regardless of the external state.

Do not allow hit of solvents in contact with components of the mechanism of a natyazhitel!

Try not to strike in the course of performance of body works on the car case around an arrangement of natyazhitel!

Do not allow heating of assembly of a natyazhitel to temperature over 100 °C!
