The dividing line between a car interior and a bouncy castle gets ever thinner. Ford is to offer inflatable rear seatbelts on the 2013 Ford Mondeo, which instantly become a kind of mini-airbag in the event of an accident. Ford says that the inflatable belt disperses the energy of a crash across a body area five times larger than would a conventional seatbelt.”We’ve tested the system extensively using our entire crash test dummy family and it offers extra protection over the standard rear seatbelt system,” said Joerg Doering, core engineering seatbelts engineer, Ford of Europe. “Bringing together the attributes of an airbag and a seatbelt is a significant development. This technology isn’t currently available in Europe.”
