My first report dealt with the theoretical analysis and verification of a simulation system for vehicle-occupant dynamic interaction. This simulation system can be used as a tool to investigate the effects of physical variables that influence automobile ride comfort. In the second report, the effects of sitting posture of seat system on human dynamic behavior were investigated. In this third report, the effects of parameters of occupant-seat system on human dynamic behavior are investigated using this computer simulation. This paper is concerned with the effects of the increase and decrease of parameters, such as the occupant's physical dimensions, characteristics of joints, length of support point of chest and thigh, spring and damping coefficients of seat cushion and so on, on human comfort. Frequency response is investigated in the frequency range of 1 to 30 Hz. As a result, it is found that these parameters exert a serious influence upon both vertical and forward and backward acceleration ratio.
