To control the vibration of the occupant by road-surface condition, we suggest a new seat cushion material (UA cell) which enclosed foaming urethane in an air cell in this study. We clarify the vibration characteristics of the UA cells by the excitation experiments and derive the theoretical model of the vibration characteristics of the UA cell. From the results, we understood that the relationship the thickness of the UA cell and that of foaming urethane had an influence on the vibration characteristics of the UA cell. When the thickness of the UA cell is smaller than the thickness of foaming urethane, the UA cells exhibit the vibration characteristics of the parallel spring which is built in foaming urethane and the air cell. When the thickness of the UA cell is larger than the thickness of foaming urethane, the UA cells exhibit the vibration characteristics of the air cell.
