1043 Operations on Seat Position of Manual Wheelchair

Abstract

We investigated autonomous propelling performance regarding seat positions of manual wheelchairs for children's usage. Tested four seat positions were front, back, up and down against an original position and its distances were the same 100mm. Estimation of propelling performance was to use pulse forces consist of average torques and holding ratios. According to our results, We found that the best position was down, because of large holding angles, almost same average torques and holding ratios. Contrary, the worst position was up, because of small holding angles and average torques. Sensitivity between propelling performance and shifting vertical direction was high compared with horizontal one.
