WALKING AID DEVICE

摘要

The object is to provide a walking aid device which adequately develops an auxiliary force for retaining a standing posture while giving a less sense of oppression when worn. To this end, waist equipment (1) for a walking aid device provided with an auxiliary power generating device (hip joint actuator (10)) at least laterally of a hip joint to impart an auxiliary force to the movement of a lower limb comprise a backrest (4) provided with pads (18, 19, 20) adapted to individually abut against the intermediate portions, opposed outer portions and right and left iliac ridges in the right and left erector muscle of spine, and a belt (5) connected to the backrest for tightening the lower portion of the rectus muscle of abdomen. This causes a support force to act on the lumbar vertebrae, stably supporting the standing posture, and reduces the resistance which the equipment applies to the curvature movement of the waist. Furthermore, since the driving torque from the auxiliary power generating device is supported by the entire region around the waist, the equipment is less caused to get out of position during movement.
