<p>PROBLEM TO BE SOLVED: To reduce a physical and mental burden by forming a seat part or a seat back part or the whole or a part of both out of an independently connectable soft belt conveyor. SOLUTION: A seat part 1 of a wheelchair is composed of a belt conveyor for peripherally moving in the advancing longitudinal direction by a conveyor belt 2 and rubber rollers 3, 4. A motor 13 is fixed on a conveyor belt support board 16, and the rubber roller 4 is rotated to peripherally move the conveyor belt 2. A seat back part 5 is also composed of a conveyor belt 6 and rubber rollers 7, 8 so as to interlock with the conveyor belt 2 of the seat part 1. In the conveyor belt 6 of the seat back part 5, a regular interval is held by the conveyor belt 2 and a connecting piece 21 connected to an outer peripheral part of bearings 17, 18 of the rubber rollers 4, 7. The opposite side is also similarly held by a connecting piece 22 to thereby reduce a physical and metal burden.</p> |
