There are six primary pieces of an airbag framework: an accelerometer; a circuit; a warming component; a dangerous charge; and the pack itself.The accelerometer monitors how rapidly the speed of your vehicle is evolving.

At the point when your vehicle hits another vehicle—or used auto parts or utility pole or deer—the accelerometer triggers the circuit. The circuit at that point sends an electrical flow through the warming component, which is somewhat similar to the ones in your toaster, aside from it warms up a ton speedier.

This touches off the charge, regularly strong pellets of sodium azide (NaN3), which detonates. The blast produces nitrogen gas (N2~) that fills the emptied nylon airbag (stuffed in your guiding segment, dashboard or vehicle entryway) at around 200 miles for every hour. The entire response takes a simple 1/25 of a second.

The sack itself has little openings that start discharging the gas when it’s filled. The objective is for the pack to flatten by time your head hits it. That way it retains the effect, instead of your head ricocheting back off the completely swelled airbag and causing you the kind of whiplash that could break your neck.

At times a puff of white powder leaves the sack. That is cornstarch or baby powder to keep the pack supple while it’s away. (Much the same as a rubberband that dries out and splits with age, airbags can do something very similar.) Most airbags today have silicone coatings, which makes this pointless.

How do airbags execute?

On account of Takata’s airbags, the inflator—the metal cartridge stuffed with charge wafers—has lighted with an excess of power. At the point when the lodging bursts, it sends metal shards flying through the pack a similar way as it is expanding—to be specific straight up at a driver’s or traveler’s head and neck.
