Hyundai Mobis' Roof Airbag (RAB) is the world's first airbag system designed to protect occupants during rollover crashes. Hidden within the sunroof assembly, it deploys in approximately 80 milliseconds to fully cover the sunroof opening and create a protective barrier between occupants and the outside environment. The system helps reduce head injuries caused by impacts with roof glass, vehicle structures, and external objects during a rollover. It also helps prevent shattered glass from entering the cabin, providing additional protection in severe crash situations. Occupant ejection is one of the deadliest consequences of rollover crashes. The Roof Airbag helps prevent occupants from being ejected through the sunroof opening, significantly reducing this risk and helping keep occupants safely inside the vehicle. Seamlessly integrated into the existing sunroof structure, the system preserves normal sunroof functionality while delivering enhanced safety performance and broad vehicle applicability.
