A description of airbags inflate as a fraction of a second after a high to moderate collision occurs

Less than 1/20th of a second in that instant, an air bag can recognize a crash, assess its severity, determine the seat occupant's position, and inflate the actual bag just the right amount it's a fraction of a second that could save your life it was a close call while driving that led an engineer in pennsylvania to.

a description of airbags inflate as a fraction of a second after a high to moderate collision occurs Whether or not to deploy an airbag is an extremely complex decision that the vehicle's “safety brain” has to make in less than a fraction of a second most car -to-car collisions last for about 70 to 150 milliseconds1,2 even though that can be less than the duration of a human eye blink, a lot happens during.

Automobile air bags like the ones in this peugeot 306 car, inflate and deflate within a fraction of a second an air bag, also known as an air cushion restraint system (acrs) or supplemental restraint system (srs), is an automobile safety device that automatically inflates upon collision to protect the. The goal of an airbag is to slow the passenger's forward motion as evenly as possible in a fraction of a second there are three parts to an the sensor is the device that tells the bag to inflate inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 km per hour.

A description of airbags inflate as a fraction of a second after a high to moderate collision occurs

The deceleration occurring after an impact is inflate − after around 35 ms the squib is activated on the front passenger side (10 ms later than on the driver's side since the passenger-side airbag is much further forward) a medium- severity front collision where the additional protective effect of the airbag is not yet. The heat from this ignition starts the decomposition of the sodium azide and the generation of nitrogen gas to fill the air bag what is particularly amazing is that from the time the sensor detects the collision to the time the air bag is fully inflated is only 30 milliseconds, or 003 second some 50 milliseconds after an accident,.
