1.6.4. A seat belt with a prednatyazhitel (the additional equipment)

The car can be equipped with seat belts with a prednatyazhitel for the driver and the forward passenger. Purpose of such belt consists in ensuring accurate fixing of the passenger in certain cases at face-to-face blow. Prednatyazhitel of a seat belt can separately work, and also together with inflatable safety cushions at face-to-face blow of sufficient force.

Fig. 1.123. Seat belt operation in an emergency

In usual conditions the seat belt with a prednatyazhitel works in the same way as a belt with a standard mode of blocking (E.L.R). (In case of sharp braking of the car the belt will be blocked. It will be also blocked in case the passenger sharply bends forward.) However, at face-to-face blow of average or big force the prednatyazhitel instantly involves a seat belt. It helps to fix accurately the passenger a seat belt and to reduce distance between them.

The system of seat belts with a prednatyazhitel consists of the components shown in drawing 1.124.

NOTE During operation of prednatyazhitel of seat belts a small amount of a smoke is allocated and there is a strong cotton. These phenomena are normal and are not dangerous. Despite that that this smoke is not poisonous, it is not necessary to inhale it as it can cause irritation or cough. After operation of prednatyazhitel of seat belts carefully wash up the person and hands.

ATTENTION After ignition key turn in the situation "ON" ("Incl.") a control lamp of additional system of passive safety of SRS (inflatable safety cushions) blinks during about 6 with then dies away. It occurs from - and that the sensor activating inflatable safety cushions of SRS is switched on in a chain of prednatyazhitel of seat belts. This lamp also lights up, if the seat belt with a prednatyazhitel is faulty.

By Prednatyazhiteli of seat belts are developed for single use. After operation prednatyazhitel of seat belts change. All seat belts should be replaced after a road accident (failure), irrespective of seat belt type.

ATTENTION After operation of a prednatyazhitel of a seat belt assembled some details of a prednatyazhitel will be hot. Do not touch them within several minutes. Do not try to check or replace independently mechanisms of seat belts with a prednatyazhitel. Do not strike on prednatyazhitel of seat belts. Do not try to serve or repair independently system of seat belts with prednatyazhitel.
