Slowly talks arose about their safety. Airbags have been under development for many years. Statistics reveal that airbags reduce the risk of casualty in a DFC by 30%. Airbags are the subject of serious governments industry research and tests. Slide 3: Newton’s second law of motion. If objects aren’t restrained they will continue moving at the speed of the moving car even if the car is stopped by a collision. All airbags need to do is to slow down passengers speed. THE BASICS OF AIRBAGS DEVELOPMENT : DEVELOPMENT WORLD WAR-2 :saw the first patent on an inflatable crash landing device for airplanes. 1980:first commercial airbags appeared in automobiles. Ever since 1988 it became a binding. Efforts to adapt the airbag was stranded due to prohibitive prices and technical hurdles. MAIN PARTS OF AN AIRBAG : MAIN PARTS OF AN AIRBAG Bag Sensor Inflation system working : working air bags are designed to inflate in frontal impacts in which the car strikes about 16 km/hr After collision senors sents an electric current to ignitor system Electric current heats the filament which ignates the capsule which in turn ignites the gas generating pallets The gas expands quickly and inflation of air bags there by takesplace,which break through a plastic cover in the steering wheel Time taken for all these things about .1sec. DRIVERS SIDE AIRBAG : DRIVERS SIDE AIRBAG Slide 8: Drivers side air bag Inflator assembly Modern types airbags : Modern types airbags Curtain airbags Developed by mercedes and volvo Inflate infront of windows to provide passengers better head and neck protection More efficient at tipping and side impacts Reduce HIC by 80% Slide 10: Head throax bag Developed by ford and renault High protection to head ITS Developed by BMW. Worlds first airbag for head protection Future of airbags : Future of airbags Smart systems Includes weight sensors Determine type occupant in seat.ie.child or adult. Infrared occupant Detect the distance of passenger from airbags Slide 12: Capacitive reflective occupant sensing Identify distance passenger from dash board Discriminate between human occupant and inanimate objects Update sensor Deploys seatbelt pretensioners faster to get benefit of airbags Air bag deployment : Air bag deployment Airbag inflation Depicits contact with airbag Coming to rest in seat and deflation of airbag All these take in 30 milliseconds Disarming airbags : Disarming airbags Disconnect battery Wait 30sec. Remove airbag fuse Drop sound insulator panel Disconnect the circuits Thus the bag is disarmed Keep the bag below 130degree celsius Airbags checks : Airbags checks When we turn key look at the dash to find airbag light for 7-10 sec.&then go out Problems occur when 1. light does not come on 2. if light does not go off after period 3. if light comes during driving CONCLUSIONS : CONCLUSIONS Air bags are of greater importance in todays vehicles siince safety of human life is of prior importance So far safe riding and for saving the precious life the safety bags must be implemented Let’s hope every automobile manufacturer implements the same Slide 19: THANK YOU...
