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


Front-Seat Sled Tests-setup

�Sled rig� Intruding door side

� Generic padding as door panel

� Front seat

� Generic EuroNCAP pulse

� Dummy� WorldSID 50%, WorldSID 5%

Improved side impact protection in the traffic of the future – car to car full vehiclecrashes with WorldSID 50%


Full-scale testsBullet & Target: Impact speed: Purpose:

2009

Mid size vs. Mid size 55 km/hMid size vs. Mid size 70 km/h Influence of Impact speedMid size vs. Mid size 80 km/h

Mid size vs. Small car 55 km/h Influence of mass ratio

2010

Older vs. Older 55 km/h Relation to real life dataOlder vs. Older 70 km/h

Plattform SUV vs. Mid size 65 km/h Influence of mass and compatibilityFrame SUV vs. Mid size 65 km/h

AE-MDB vs. Mid size 60 km/h Potential future load case

Mid size versus Mid size 70 km/h / 30 km/h Representative intersection crash


Intersection crash


Intersection crash�AIS3+ Injury risks (Petitjean et. al 2009, survival method)

Shoulder 1.5 %

Thorax / Abdomen

Pelvis 24.0 %

1.0 %


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

Additionally...


1. Pelvis loading

2. Occupant-to-Occupant Interaction

3. Rear-Seat

4. Senior occupants

Future focus for side impact protection


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
