1. AIR BAGS PRESENTED BY YAGVENDRA NATH REG.NO.: 0601222342 BRANCH: MECHANICAL

2. INTRODUCTION INTRODUCTION  PROVIDES PASSIVE RESTRAINT IN OUR CARS  ALTERNATIVE FOR SEAT BELTS  RISK REDUCTION

3. THE BASICS OF AIR BAGS THE BASICS OF AIR BAGS  LAWS OF MOTION  MOMENTUM FACTOR  MASS FACTORS IN THE VECHILE  AIR BAGS SLOWS THE PASSENGER TO REST WITH LITTLE OR NO DAMAGE

4. MAIN PARTS OF AIR BAGS MAIN PARTS OF AIR BAGS  BAG  SENSOR  INFLATION SYSTEM

5. SPRING AND ROLLER TYPE SENSOR

6.  BY FUNCTION, THERE ARE 2 TYPES- IMPACT SENSORS AND SAFING SENSORS.  THE FORWARD SENSORS ARE LOCATED IN VARIOUS LOCATIONS FORWARD OF THE PASSENGER COMPARTMENT.  REAR SENSORS ARE ALSO KNOWN AS SAFING SENSORS AS THEIR FUNCTIONS IS TO DETERMINE THAT A CRASH HAS OCCURRED.  THE REAR SAFING SENSOR MUST CLOSE BEFORE THE FORWARD SENSORS TO AVOID AIRBAG DEPLOYMENT IN CASES WHERE THE IMPACT IS NOT SEVERE ENOUGH TO CAUSE DEPLOYMENT.

7. WORKING OF AIR BAG WORKING OF AIR BAG  AIR BAGS DESIGNED TO INFLATE IN FRONTAL OR FRONTAL ANGLE IMPACTS  AFTER COLLISION SENSOR SENSE AN ELETRIC CURRENT TO IGNITER STSTEM  CURRENT IN IGNITER SYSTEM HEATS A FILAMENT WHICH IGNITES A CAPSULE  IGNITED CAPSULE SUPPLIES THE HEAT TO IGNITE GAS – GENERATING PELLETS

8. MODERN TYPE OF AIR BAGS MODERN TYPE OF AIR BAGS  CURTAIN AIR BAGS – THESE BAGS INFLATE IN FRONT OF VEHICLE WINDOWS TO PROVIDE PASSENGERS BETTER HEAD AND NECK PROTECTION  HEAD – THORAX BAG – IT PROTECTS THE HEAD INTRODUCED IN 1998 -DEVELOPED BY FORD AND RENAULT  INFLATABLE TUBULAR STRUCTURE- INTRODUCED IN BMW CARS- CONSISTS OF UNIQUE NYLON TUBE INSTALLED IN THE HEAD- LINER ABOVE THE FRONTAL DOORS THAT INFLATES TO DIAMTER OF 15 CM

9. FUTURE OF AIR BAGS FUTURE OF AIR BAGS  SMART SYSTEMS- WEIGHT SENSORS- TO CLASSIFY PASSENGER  INFRARED OCCUPANT DETECTION- TO DETECT THE DISTANCE OF PASSENGER FROM THE AIR BAG AND TO ADAPT THE FORCE OF DEPLOYMENT  CAPACITIVE REFLECTIVE OCCUPANT SENSING- TO IDENTIFY DISTANCE AND DISCRIMINATE BETWEEN HUMAN AND GROCERIES  UPDATED SENSORS- HELPS PASSENGERS TO GAIN MAXIMUM FROM AIR BAGS

10. CONCLUSION CONCLUSION  THE AIR BAGS (ARE OF GREATER IMPORTANCE IN TODAYS VEHICLE SINCE SAFETY OF HUMAN LIFE IS OF PRIOR IMPORTANCE. AS THE COUNT OF AUTOMOBILES ARE INCREASING PROBABILITY OF ACCIDENTS IS ALSO MORE.FOR A SAFE RIDING AND FOR SAVING THE PRECIOUS LIFE SAFETY BAGS MUST BE IMPLEMENTED. LETS HOPE AUTOMOBILE MANUFACTURERS IMPLIMENT THE SAME SINCE THE SAFETY FOR LIFE IS INEVITABLE
