The Influence of Seat-Back and Head-Restraint Properties on the Head-Neck Motion During Rear-Impact

• One type of production-car front-seat with ahead-restraint was tested in simulated low-velocityrear-impacts using a Hybrid III-dummy fitted with amodified neck (RID-neck). The seat was modified invarious ways to test the influence of different seatproperties on the head-neck motion during theimpact.The results show that it is possible to influencethe head-neck kinematics to a great extent bymodifying the properties of the seat-back and thehead-restraint. It was possible to virtually eliminatethe neck extension motion during the rear-impactand this will hopefully result in a significantdecrease of the neck injury risk in real world rearimpacts.
