How fast can airbags deploy? What can multistage devices do?

• A. 5 milliseconds; Multistage devices can adjust speed and inflation
• B. 10 milliseconds; Multistage devices can adjust speed and inflation
• C. 60 milliseconds; Multistage devices can adjust speed and inflation
• D. 30 milliseconds; Multistage devices can adjust speed and inflation

Answer: (D)

Airbags must deploy in an ultra-fast time, measured in tens of milliseconds, so they can cushion you before contact with the vehicle interior. A typical deployment timing cited in training and industry references is about 30 milliseconds after the crash sensors trigger. That speed is essential to begin distributing forces across the body right away. Multistage inflators take this a step further by adjusting how quickly and how much gas is released. In a mild crash, they can use a smaller charge for a gentler, slower inflation to reduce the risk of injury from a hard, rapid fill. In a severe crash, they can deploy a larger charge for a fuller, faster inflation to maximize protection. This capability to tailor both the timing and the amount of inflation helps airbags provide the right level of support for different crash scenarios, occupant sizes, and seating positions. So, the best pairing is a deployment time around 30 milliseconds with the ability for multistage devices to adjust both speed and inflation.
