Conclusions
�Different kinematic behavior for WSID 5% compared to SIDIIs
�Difference in deflection measurement for WSID 5% vs SIDIIs
�Need of reliable and acceptable risk functions� Dummy comparison� Front- and rear seat comparison
�More measurements in pelvis

Project Highlights
• WorldSID improved tool for side impact evaluation
• Good structural integrity of all target vehicles
• SAB presence reduce the occupant thoracic injury risk
• Thorax Injury Risks < 10% for a 45 year old occupant

WorldSID related Conclusions
WorldSID – good tool for evaluating overall side impact occupant protection.
� Spine kinematic� Bi-lateral loading � Ability to measure low and high crash severities� Different response from different side airbag concepts
Specific points of interest:
� Rib rotation� Shoulder kinematics� Pelvis measurement and injury risk
