11.44. Safety pillows

Safety pillows (System of pneumosafety SRS) are intended for protection of the driver (and the passenger) on a forward seat in case of collision.

On a part of cars 2 pillows are provided, one of which (from outside the driver) is mounted in the central part of a wheel, and another – in a ceiling part перчаточного a box. The system also includes the management and diagnostics block mounted under the forward panel on the centre of the car.

The safety module from outside the driver

The module structure includes the packed pillow and the device forcings (reactor) which is under a pillow and is connected to it an aperture through which gas moves at signal receipt.

The signal moves on a cable winded in a flexible spiral round a shaft of a wheel, irrespective of a wheel angle of rotation. The pillow is inflated with the nitrogen formed as a result of reaction oxide of copper and азида of sodium.

The safety module from outside the passenger

The module structure includes the device the forcings (reactor), the combined pillow, the reactor and the facing panel.

Pillow of the passenger much more than a pillow of the driver. A pillow support is the steel case of the reactor.

At надувании pillows the seam of the facing panel breaks.

The management and diagnostics block

The block provides a food and operation of a pillow of safety even at the disconnected battery.

The block checks a condition of system of safety. The control lamp of system (lamp AIR-BAG) at first lights up and at serviceable system dies away.

If the system is faulty, the lamp continues to burn or blink (or the sound signal) is distributed. In this case it is necessary to hand over the car immediately in car-care centre for check.

The prevention

Switching-off of system of pneumosafety: the neglect safety measures leads to casual disclosing of a pillow and to serious traumas.

At performance of any works near to a steering column or any unit of system it is necessary to disconnect safety pillows.

Switching-off of a pillow of safety

1. Expose wheels in driving position on a straight line and translate the ignition key in position LOCK.
2. Disconnect the battery from weight.
3. Start works after not less than 2 mines, necessary for the condenser category.

At manipulations with the pillow container always hold the revetted party of the container in a direction from itself. It is forbidden to put the container the revetted party downwards. It is forbidden to measure resistance of any unit of system of pneumosafety as operation of a pillow from an ohmmeter battery is possible.

Before performance of welding works disconnect a socket of a pillow of safety of yellow colour which is located under a steering column about a socket of a combination of switches (from outside the driver) or перчаточного a box (from outside the passenger).

It is forbidden to throw out the container with a pillow.
