On the majority of models the system of a tension of a seat belt of forward sitting which is intended for an ubiraniye of sagging of a seat belt at a head-on collision is established. Each belt of forward sitting has the system of a tension which fastens to an inertial drum of a seat belt. The mechanism of a tension of a seat belt copes the electronic control device of a safety cushion. The system of a tension of a seat belt works at the head-on collision which size exceeds a certain value.
The system of a tension of a seat belt will not work at blows behind and a head-on collision, if size of blow of less certain size.
At operation of system of a tension of a belt burns down fuel in the cylinder of the mechanism of a tension and as a result it the piston up moves and eliminates sagging seat belt system at the expense of fixing of an inertial drum by the steel cable attached to the piston. If worked the tension mechanism, further a seat belt it will be fixed, and it is necessary to replace knot.
For an exception of operation of the mechanism of a tension of a belt at work with a seat belt remove a weight wire from the accumulator and disconnect the electric socket from the tension mechanism.
Prevention
If there was a casual falling of the mechanism of a tension of a seat belt, it is necessary to replace it, even if on it there are no mechanical damages. Exclude hit on the mechanism of a tension of a seat belt of any solvents.
