How air bags reduce injury?

Question

other than preventing you from colliding with hard objects

Answer 1

With input from a separate rollover sensor, some curtain SABs can be designed to also deploy as rollover air bags in the event of a rollover.

Rollover air bags stay inflated longer to help keep you inside the vehicle.

Ejection is the most common source of injuries and fatalities in rollover crashes.

Rollover air bags, along with properly worn safety belts, reduce the risk of injury and ejection.

Answer 2

That is it!
