Most collisions have three separate impacts: (1) the vehicle collision; (2) the collision of the occupant with the vehicle interior; and (3) 'third strike', the collision between the occupant's internal organs and his body. The 'third strike' and other mechanisms for injuring the head cause about 100,000 fatalities and 90,000 disabilities worldwide each year. Thus head injury research has become one of the most important areas of occupant protection research; it aims to understand the mechanisms of brain damage better, and derive representative criteria for safety testing. Many countries are introducing new legislation aiming to protect the head from impacts with the vehicle interior. Improved upper trim protection benefits both restrained and unrestrained occupants. From 1 September 1988, 10% of vehicles sold in the USA were required to comply with the upper interior trim requirements of Federal Motor Vehicle Safety Standard (FMVSS) 201, which is designed to improve occupant protection in a collision; it will apply to all passenger vehicles sold from 1 September 2002. This article describes research by Daewoo Motor Company on head impact testing; topics that it covers include simulation, rapid prototyping, test equipment, velocity generator system, targeting, head support, and data collection.
