HALF-SITTING POSTURE ASSIST DEVICE, HALF-SITTING POSTURE ASSIST METHOD, AND HALF-SITTING POSTURE ASSIST PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a half-sitting posture assist device and the like which can reduce a load applied on a user's body in a half-sitting posture.SOLUTION: The half-sitting posture assist device includes: drive means M operating a drive mechanism part assisting a user's knee for bending and extending by means of torque application; control means 62 controlling the drive means M to be driven; and detection means 65 detecting an angle of a knee joint of the user. The control means 62 controls the drive means M to be driven such that a torque, which is at the same value as a reference torque applied on the drive mechanism part due to self-weight, is applied in a direction for assisting the user's knee for extending when an angle of the knee joint detected by the detection means 65 during bending operation reaches a predetermined angle.SELECTED DRAWING: Figure 2
