13:31. Natyazhitel of a seat belt
Mechanical natyazhitel of a seat belt (model with 03.1993 on 08.1996 g of the issue)
Natyazhitel of a seat belt is established in forward seats. It provides a dense prileganiye of a seat belt to a trunk of the person at head-on collision of the car and interferes with slipping of the person under a belt. The device works at head-on collision and a deviation of a trunk on the 30th hail., and also when braking with loading not less than 6G.
At operation of a natyazhitel previously compressed spring (the effort accumulator) (1) involves through a cable (2) and blocking of reverse motion (3) the belt lock on 80 mm down. Thus, the free wheeling of seat belts approximately decreases by 80 mm.
Components of a mechanical natyazhitel

|
1 — the effort Accumulator 2 — the Cable 3 — Blocking of reverse motion |
Operation of a natyazhitel is determined by a yellow uvula in the belt lock on the party turned to a seat. After operation of a natyazhitel seat belts function as usual.
Natyazhitel does not demand maintenance. After operation it needs to be replaced in a set.

Before utilization of not worked natyazhitel it is necessary to provide forcibly its operation (work HUNDRED). For an exception of involuntary operation of the device of a tension when carrying out any works with front seats and before their removal it is necessary to fix surely on the effort accumulator a plastic safety fork. |
Pyrotechnic natyazhitel of a seat belt (model from 09.1996 g of the issue)
At accident the control unit of the SRS system sets fire to the pyro installed in a natyazhitel. The gases which are formed at the same time move the piston in a pipe of a natyazhitel forward. The piston is connected by a cable with the belt lock. The lock moves down and at the same time the free wheeling of seat belts approximately decreases by 80 mm.
Operation of the device of a tension of a belt is followed by fire of a control lamp of the SRS system. In addition operation of the device of a tension is determined by a yellow uvula in the belt lock on the party turned to a seat. After operation belts function as usual.
Natyazhitel does not demand service. After operation it needs to be replaced in a set.

Before utilization of not worked natyazhitel it is necessary to provide forcibly its operation (work HUNDRED). For an exception of involuntary operation of a natyazhitel and a safety cushion and for safety of operation it is necessary to carry out the rules listed in the Section of the Security measure at the address with an emergency prednatyazhitel of a seat belt and a side safety cushion. |
