The aim of this study is to design a pelvic airbag cushion system for absorbing falling impact energy. The American National Safety Council announced that 50.7% of accidental household fatalities were old people. In Korea, persons above sixty years old encountered more accidents than persons below sixty, too. From the analysis of old people`s accidents in Korea, 55.3 percent of accidents were falls and slips, 7.5 percent were conflicts, and 4.5 percent were getting cut or being torn by an object. The result shows the importance of old people`s injury prevention from falls or slips. Old people`s characteristics for falling were identified to develop a product to prevent old people`s injury from falling. Design directions considering old people`s characteristics for falling were proposed for the design. Finally, design of the pelvic airbag cushion system for absorbing falling impact energy was developed
