The idea is that a side airbag will help prevent head or limb damage from being jostled within the vehicle. If the crash is severe enough, the sensors signal inflators to fill the bags with gas in a fraction of a second. A new study of crashes in which belted rear-seat passengers were killed or seriously injured suggests better restraint systems are needed. If the speed is high enough and the collision fits the required parameters, the corresponding airbags will deploy.
