With the increase in elderly population rate, interest in development of equipment to aid for the elderly activities has been increased. Since the physical features of repetitive behavior of elderly people standing and sitting can cause the stress on certain parts of the body, The necessity of developing Lift Chair concerning the foregoing problem has been to the fore. In this study, we set the average body size of the elderly aiming to develop non-motorized Lift Chair, developed Non-motorized tilting mechanism based on the Muscle strength change at knee angle, and did a study relatively inexpensive Lift Chair considering esthetic and practicality.
