"Mercedes-Benz is pursuing its safety initiative in the rear of vehicles with the Beltbag," comments Prof. Dr.-Ing. Rodolfo SchŲneburg, Head of Passive Safety and Vehicle Functions at Mercedes-Benz Cars. "After all, the excellent standard of safety offered by Mercedes-Benz doesn't just apply to all model series, but to all seats, too."
However, Mercedes is not the first car maker to offer a seatbelt airbag. Ford and Lexus debut their version of the passive safety feature in the Explorer and LFA model in 2010 respectively. Unlike Mercedesí system, Fordís seat belt airbag is triggered by both side and frontal impacts.
Under normal usage, research showed that the Mercedes Beltbagís added thickness improves passengerís comfort too. Mercedes do not plan to introduce the Beltbag for the front occupants, as frontal airbags are already included on all models as a supplementary restraint system.
