THESE ARE DESIGNED TO KEEP YOUR HEAD , NECK , CHEEK FROM SLAMMING INTO THE DASHBOARD, STEERING WHEEL OR WIND SHIELD. WHEN A COLLISION IS OCCUR , DUE TO COLLISION CAR IS STOP BUT THE PASSENGER INSIDE WILL CONTINUE TO MOVE UNLESS THEIR MOMENTUM IS DESTROYED. THE OBJECTIVE OF USING THE AIR BAG IS TO SLOT ON THE OCCUPANTS SPEED TO ZERO WITH LITTLE OR NO DAMAGE UNDER THE FOLLOWING CONDITION
1. THE SPACE BETWEEN THE PASSENGER AND THE STEERING WHEEL OR DASHBOARD IS VERY SMALL.
2. THERE IS ONLY FRACTION OF SECOND TIME AVAILABLE
THE AIR BAG CONSISTS OF FOLLOWING COMPONENT
THE BAG IT IS MADE UP OF NYLON FABRIC. IT IS FOLDED INTO THE STEERING WHEEL OR DASHBOARD OR DOOR.
SENSOR IT IS THE DEVICE THAT TRIGGER THE INFLATION OF THE BAG. THE SENSOR RECEIVE INFORMATION FROM ACCELEROMETER WITH IN A MICRO CHIP WHEN A COLLISION OCCUR WITH A FORCE EQUIVALENT TO RUNNING A CONCRETE WALL AT ABOUT 20 KPH. A ELECTRICAL CONTACT IS CLOSED WHICH FLIPPS A MECHANICAL SWITCH TO FIRE THE THE PROPELLANT.
INFLATION SYSTEM IT USE A SOLID PROPELLANT AND IGNITER . THE PROPELLANT UNIT CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE . WHEN FIRED BY THE SENSOR , THESE REACT TO PRODUCE NITROGEN GAS WHICH INFLATES THE AIR BAG QUICKLY . THE TIME TAKEN IS OF MILLISECONDS . WHEN FULLY INFLATED , THE PRESSURE IN THE AIR BAG IS 80 MPa AND THE PROPELLANT UNIT HEATS UP TO 160`C. A SECOND LATER , THE GAS QUICKLY DISSIPATES THROUGH TINY HOLE IN THE BAG , THUS DEFLECTING THE BAG.
