Development of a Wearable Chair

Abstract

We have developed wearable chairs for various people. If an elderly person gets tired while walking, he/she can sit down and take a rest at any time, so that he or she can expand their range of motion. If a worker has to work in a crouching posture for a long time, using this device can reduce the burden on the body. This device is designed so that it can be stored as small as possible, and at the time of sitting, the support polygon is as large as possible, and the center of gravity is at the center. The muscle activity of the thigh was measured by changing the height of this chair. As a result, it was found that the lower the chair, the lower the muscle activity when sitting down, but the higher the chair, the lower the muscle activity when standing up, and the easier it is to stand up.
