Fig. 1.34. Elements of system of passive safety of passengers of forward seats: 1 – the forward gauge of blow; 2 – an alarm lamp of system of pillows of safety; 3 – преднатяжители seat belts; 4 – the gauge of pillows of safety
Degree of safety of the driver and the passengers fastened by belts, is provided thanks to installation преднатяжителей
3 (fig. 1.34
) seat belts and pressure terminators.
At head-on collisions of average or big force pyrotechnic преднатяжители instantly press bodies of the driver and the passenger to backs of seats.
The system pyrotechnic преднатяжителей seat belts works only at the included ignition. Pressure terminators reduce a pressure force of seat belts by a body of the driver and the forward passenger in case of collision.

3. If any of forward seat belts is not involved in the inertial coil or cannot be extended owing to malfunction or operation преднатяжителей.
4. Damages преднатяжителей forward belts безопасености or areas being near to them.
