Abstract
Transfer from wheelchair to bed is difficult for wheelchair users without assistance. Because they must lift up their bodies and move from wheelchair to bed by themselves while transfer. Some lift or assist system called transfer aids are developed to help transfer, but even so they need assistance. Lifts need large space to use and it cannot be carried easily. Some transfer aids need to improve the wheelchair to attach. The aim of our study is to develop a transfer aids by self-help model that can use easily by wheelchair users themselves. This transfer aids can attach to wheelchair without improvement. And it can be carried easily so wheelchair users can use everywhere. Wheelchair users can spread transfer aid manually. If wheelchair user has severe damage in hands or fingers, user cannot spread transfer aid. Therefore, we developed spread mechanism driven by motor. Only with the simple operation of the switch, wheelchair users can spreads the transfer aid easily.
