Description of safety cushions

General instructions on safety cushions

The pillow represents part of the general concept of passive safety.

At dangerous frontal collisions the system of forward safety cushions together with three-point seat belts provides additional protection of area of the head and thorax of the driver and forward passenger.

At strong side crashes lateral and head pillows reduce danger of damages of the passengers who are in a blow zone

Seat belts, along with their traditional protective function, have to hold in case of accident the driver and the forward passenger in such situation that pillows could reveal and provide additional protection correctly.

Security systems work only at the included ignition. Readiness of function of pillows is controlled by electronics and brought to indication by means of a control lamp of "airbag".

The main components of system of pillows are

The electronic control actuation device (the control unit and sensors) both forward pillows lateral and head pillows a control lamp in a control panel.

The following testifies to malfunction of system

At inclusion of ignition the control lamp does not light up, the control lamp does not die away about 3 seconds later after ignition inclusion, after ignition inclusion the control lamp dies away and lights up again, the control lamp lights up or blinks during the movement.

Under what conditions work safety cushions?

Safety cushions work at dangerous collisions.

Safety cushions of the driver and the forward passenger work at dangerous frontal collisions.

At strong side crashes lateral pillows work together with a head pillow of the relevant party of the car.

In special emergencies can work both forward, and lateral pillows together with the corresponding head pillow.

Safety cushions do not work at easy frontal and side crashes, arrivals behind and capsizing of the car. In such situations of passengers traditionally protect the fastened seat belts.

Factors of disclosure of pillows

There are no uniform criteria of operation of pillows in each concrete situation. It is explained by the extremely different specifics of accidents. An important role is played, for example, by such factors as properties of object of collision with the car (firm, soft), a collision corner, car speed, etc.

Condition of operation of safety cushions in case of collision delay size is decisive. Car sensors together with the control unit define severity of accident and by that promote purposeful and timely operation of system of laying and a tension of seat belts. Safety cushions do not work at collision when sizes of delay of the car are lower than the programmed control unit sizes though owing to accident quite strong deformation of the car is possible.

At inflation of a pillow the smoke is formed. It normally and does not testify to ignition of the car.
