Daimler Developing Active Seat-Belt Technology for Rear Passengers

By Trevor Dorchies | February 08, 2012
Despite the nuisance, seat-belts have been a life-saver for millions of motorists since legislation was first enacted in 1961. Yet, even with numerous campaigns and federal laws, some people still forego the belt. Daimler is hoping to convert those who think a seat-belt is a hindrance by developing an advanced and more comfortable, intelligent seat-belt system for rear passengers. The active seat-belt buckle moves with the occupant, restraining, tightening and loosening as the system determines. The belt can be extended as far as 70 millimeters and retracted as far as 40 millimeters. The belt buckle itself is attached with a cable to a spindle nut, and an electric motor pulls and loosens the cable. This new feature will be installed into many Mercedes-Benz models, though Daimler has not stated exactly which ones and when. The buckle itself rises out of the backseat when the rear door is opened and illuminates to be seen easier. Daimler believes simplifying the process of buckling up will make more people want to do just that. The active seat-belt buckle also has PRE-SAFE, another safety system integrated into it as well. PRE-SAFE kicks into action whenever critical driving situations arise or an accident actually occurs. When the vehicle detects another object approaching fast in the front, the seat-belt tightens up to hold the occupant in place. This new system compliments the pyrotechnic belt tensioning which has been a standard feature on Mercedes-Benz models for years now and kicks in when an accident has occurred. In the actual event of an accident, Daimler has designed the active seat-belt buckle to release as soon as the rear doors have been opened. This system sounds flawless, but if the on-board electrical system is severed from the vehicle during the accident, the seat-belts won't release on its own.
