Натяжитель a seat belt. The basic data and security measures

Натяжитель a seat belt it is established in forward seats. It provides at face-to-face blow dense прилегание a seat belt to a trunk and interferes with sliding of the passenger under a belt. Joins tensioner at strong face-to-face blow by an electronic monitor by a pillow of safety/natjazhitelem of a belt. Depending on weight of failure the monitor includes either only tensioner a belt or in addition also a safety pillow.

By means of a monitor in натяжителе a belt the small charge ignites. Gases formed at explosion put forward in a pipe натяжителя the piston which is connected with the belt lock through a rope. Thus the belt lock lasts downwards in such a manner that idling humeral and тазового a belt is reduced.

Worked tensioner a belt it is defined on fire of a control lamp of a pillow of safety/natjazhitelja of a belt. In the worked condition the seat belt works as if tensioner is absent. Натяжитель a belt does not demand leaving. After its operation it is necessary to replace in the complete set.

Before recycling not worked натяжителя its belt it is necessary to neutralise compulsorily (work HUNDRED).

For prevention of casual operation натяжителя a belt and a safety pillow it is necessary will familiarise with safety rules of the reference with a seat belt, address to Section the Steering with the hydraulic booster (сервоуправление).

Security measures at the reference with натяжителем a seat belt

- Replacement and system check tensioner a seat belt/pillow should be spent on HUNDRED. It is not supposed to carry out any constructive changes.
- If owing to failure tensioner a belt has worked, it it is necessary to replace on new (work HUNDRED).
- Before performance of works with натяжителем a belt it is necessary to disconnect a negative cable (-) the storage battery. After that it is necessary to isolate a negative pole on batteries to exclude casual contact with it.
- Removed, but not used tensioner a belt, at long car repairs it is necessary to store under the lock.
- Knot натяжителя a belt and a monitor are sensitive to blows. If they fall from height more than 50 sm, to establish to the place of them it is impossible.
- At carrying out of welding the plug of the welding device should join directly a welded detail. In any case the monitor is necessary for disconnecting from a cable.
- The monitor of a pillow of safety/natjazhitelja of a belt is under the central console. For an exception of functional infringements near to it it is impossible to hold magnetising subjects.
- натяжителя the belt and the safety device cannot even be subjected knot quickly to temperature influence above +90С. The damaged elements are not subject to repair. The pillow of safety/natjazhitel of a belt is not supposed вскрывание elements of system. Before installation once again check up, whether the negative cable is disconnected (-) and whether the negative pole of the storage battery is closed.
- At all it is not necessary to remove and utilise independently tensioner a belt. There is a danger of explosion!

System check

- At ignition inclusion a control lamp of system the pillow of safety/natjazhitel of a belt should light up and go out later 4 with.
- If the control lamp at ignition inclusion does not light up, it specifies in malfunction presence in system. If the lamp does not die away or lights up during movement, in system the pillow of safety/natjazhitel of a belt is available malfunction. Thus it is necessary to mean that the system is not efficient.
