Hyundai Mobis said Thursday that its air bag that ejects out from the sunroof has been evaluated and shared by the US National Highway Traffic Safety Administration.

The first kind to be invented in the world, according to the firm, the roof air bag is unfolded when a vehicle is flipped over during an accident. It can cover the entire roof in 0.08 seconds, aimed at protecting passengers inside the car from being ejected out of the sunroof. The new system involves 24 patented technologies and has been enhanced for mass-production in collaboration with Inalfa Roof Systems last year, the company said. 

Since developing the world’s first panoramic sunroof air bag in 2017, Hyundai Mobis has been focusing on launching advanced air bag technologies for global markets. It has been mass-producing air bags since 2002. 

In January, NHTSA gave a presentation on the status of its roof ejection mitigation research at an event hosted by the Society of Automotive Engineers, which included a case of Hyundai Mobis’ roof air bag. 

NHTSA is a US government agency which studies ways to prevent injuries and reduce economic costs caused by road traffic crashes, via education, research, safety standards and enforcement activities.
