Abstract
Recently, the user of wheelchair is increasing. There are many accidents of falling from wheelchair. In this paper a system to prevent falling from wheelchair is proposed. The wheelchair quips an chair-inclining mechanism for changing angle of wheelchair in sideways. This system can lean a wheelchair 10 degree approximately and carry out up-and-down movement of wheelchair. We designed a prototype machine of this system and experimented in order to investigate the relation between angle of wheelchair and displacement of actuators.
