Pedestrian protection airbag : IVSS project report Erlingfors, Mats ; Östling, Martin
Publication details: Borlänge IVSS, Intelligent Vehicle Safety Systems, 2009Description: 15 sSubject(s): Online resources: Abstract: There are approx. 8000 pedestrians fatalities within EU every year, and many more are injured when colliding with a vehicle. The most sever injuries are head injuries when impacting the vehicle front, valid for both children and adults. It's the "hard structure" under the bonnet, lower part of the windscreen area (cowl area) and the A-pillar structure where the most severe head injuries occurs. This project has been developed a pedestrian friendly airbag, that lifts the rear end of the bonnet to increase absorption distances toward engine bay and structure, the bag is also covering the A-pillar structure and lower part of windscreen area. This protective system will significant reduce the injury severity when impacting these areas. Catia designs and physical prototypes has been developed and manufactured. The system performance has been verified by physical testing. Future rating (i.e. EuroNCAP) will demand a higher pedestrian protection level to be an overall safety top ranked vehicle. By developed this protective system that fulfils EuroNCAP demands, both VCC and Autoliv are well prepared toward competitors.There are approx. 8000 pedestrians fatalities within EU every year, and many more are injured when colliding with a vehicle.
