Design of Electric Assist-standing Chair for Persons with Disability Design of Electric Chair to Assist Person with Disability in Stand up and sitting down

In this paper, we propose the assist chair for standing and sitting that composes the lifting mechanism for low seat. And We developed the entrapment sensing mechanism to consider the safety of lifting mechanism. And We designed the arm-rest to be controllable the 90[deg]. Lifting function and entrapment sensing mechanism are controlled assistive-control system. In experimental result show that the proposed lifting chair can sense the obstruction and adjustable the height of seat.
