Safety cushion for the driver of SRS system (additional damping)
The safety cushion of SRS system is intended for increase of safety of the driver and is an additional tool of damping along with seat belts.
At strong face-to-face blow the pillow is inflated, owing to what provides blow mitigation along with seat belts and reduces probability of blow of a thorax or the head of the driver about a steering wheel.
At strong face-to-face blow the sensor registers braking and causes operation of the inflatable device of a pillow. In the inflatable device there is a chemical reaction as a result of which the pillow is instantly filled with nitrogen (gas is nontoxical), constraining movement of the driver by inertia. Naduvaniye of a pillow is accompanied by quite loud sound and smoke allocation. These processes harmless also do not mean a fire. As soon as possible wash out the remains of the substances participating in gas evolution, as probably insignificant irritation of skin.
Expansion of a pillow occurs for fractions of a second and consequently at a naduvaniye the considerable mechanical effort develops. The system is intended for decrease in probability of receiving serious traumas, however application of an in itself pillow can cause insignificant damages of an integument in the form of burns, blisters and grazes.
Within several minutes the nave of a steering wheel can remain hot, but the pillow will not heat up. The safety cushion is calculated on single application.
The safety cushion works from a strong face-to-face push within the shaded area limited to shooters.
Naduvaniye of a safety cushion occurs if force of a push exceeds design norm which corresponds to force of collision with motionless absolutely firm wall at speed of movement of the car of 20 km/h.
This threshold is obviously exceeded at collision of the car with a barrier which starts moving or deformed at counter blow (for example with the parked car, or with a road column), or at noncentral blow (blow at which the nasal part of the car as though approaches under an obstacle and in collision does not participate, for example under a truck frame).
The safety cushion does not work at blow behind, lateral blow or at a car perevorachivaniye, and also at face-to-face impact on small speed.
Safety cushions for the driver and the passenger The safety cushion works even in the absence of the passenger on a forward seat. If force of blow corresponds threshold, one of two safety cushions provided in the car will work. The touch device of safety cushions consists of two sensors – the threshold sensor and the safety cushion sensor. At strong face-to-face blow sensors register sharp braking and cause operation of the inflatable device which inflates a pillow with nitrogen.
