A LIFESAVING concept that could reduce injury beyond current protection systems and help cut employer liability in road accidents will be unveiled by Mercedes-Benz at the Frankfurt International Motor Show. PRE-SAFE recognises a potential collision in advance and activates protection systems before impact, including new seatbelt tensioners and automatically adjusting seats.

The concept is based on the findings of Mercedes accident researchers which show that in about two-thirds of incidents there is a relatively long time between recognition of an impending accident and the impact itself. Other systems like extending bumpers, smart crash boxes in the front end structure or movable interior components are possible, along with systems which keep occupants away from deformation zones.

Dr Rudolf Schoeneburg, head of safety development at Mercedes-Benz, said: 'Our present protection systems such as airbags, windowbags or belt tensioners must ensure safety in a matter of milliseconds, even though accident recognition can be measured in seconds. Making use of this interval opens up new dimensions in occupant protection.'
