Occupant Injury Optimization for Non-Airbag Vehicles 2003-01-3752

The Restraint System and interior design (seats, steering wheel, etc) are critical for Vehicle Occupant Injury performance. Assuming a given Vehicle pulse the restraints and interior design determine the dummy kinematics. Furthermore, some interior characteristics (shape, material, thickness, etc) have direct influence on Occupant's Body Energy Absorption. The paper describes a Non-airbag interior development to meet Head Impact Criteria (HIC) as per FMVSS208 Frontal Impact requirements. Several proposals were assessed by CAE and component and vehicle level testing on their influence on Occupant Kinematics and Dynamics. After a few design iterations, a significant reduction in HIC value was achieved.
