AIRBAGS IN AUTOMOBILES

AIRBAGS IN AUTOMOBILES

INTRODUCTION :

Air bags are designed to keep occupants head, neck, and chest from slamming into the dash, steering wheel, or windshield in a front-end crash in a fraction of second. Air bags are fabric bags that are filled quickly with a gas to provide supplement protection for vehicle passengers during some collisions. Typically air bags are designed to deploy in crashes that are equivalent to a vehicle crashing into a solid wall at 8 to 14 miles per hour. Air bags are most effective in protecting vehicle occupants who are properly belted. One or more sensors detect intensity and direction of vehicle deceleration during a collision. The sensor sends an electric signal to start a chemical reaction that inflates the air bag with harmless nitrogen gas. Air bags have vents, so they deflate immediately after cushioning you. If there is sufficient change in velocity in the direction of protection (frontal or lateral), appropriate air bags are deployed. On impact, air bag system senses the crash, inflate, and then deflate all in the blink of an eye. They cannot smoother occupant, and they don’t restrict occupant’s movement. The smoke appears in a vehicle after an air bag demonstration is the nontoxic starch or talc that is used to lubricate in the air bag.
