Some airlines are now turning to something that’s standard in cars to help meet new safety regulations: airbags. While they’re already being installed on Virgin Atlantic, Air Canada, and Air New Zealand planes, Delta will become the first American carrier to install new airbags next year.

Unlike car air bags, these inflate not in front of the passenger, but actually from their seatbelts. This means that it’s less likely that a fast-deploying airbag will injure you, and will probably help protect you instead. They’re meant to help those most at-risk in survivable crashes, like people in lie-flat beds. Mostly, they’ll be deployed for first and business-class passengers who may be at risk of being thrown into bulkheads, seat dividers, galleys or other hazards.
