Abstract

Computer simulation is used to analyze occupant impact response under the influence of airbag and seat belt as a step toward identifying a design strategy that would enable them to function in a complementary manner. The CAL3D occupant simulation program will be used here. This program has been used by engineers as a design tool for restraint systems. It predicts the occupant impact response based on dynamic principles. Due to its low cost and high speed, this tool allows one to investigate a great number of design alternatives, which would be prohibitive using experiments. Two types of Adaptive Restraint System (ARS) are discussed. These ARS designs utilize additional restraint features such as the belt pre-tensioner load limiter and incorporate embedded logic to determine whether the seat belt should be locked and whether the airbag should be deployed according to the impact conditions. Design studies for these ARS are also discussed.
