Abstract
Proper seating is very important for the severe cerebral palsy patients, and has good influence on patients' physical body and mentality. The deformity of the spine causes a gap between a back of a patient and a wheel chair backrest. Generally, urethane cushions are used to fill up the gaps. However, this method cannot completely handle the deformation and posture of users. In this paper, we have developed automatically transformable seating system with air pressure. As a preliminary of the development, we conducted characteristic tests for the rubber bag. Additionally, we developed an intelligent seating system (i-Seating) and we conducted back pressure tests of the i-seating over the wheel chair and desk.
