Title:
MOTION ASSISTANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/235574
Kind Code:
A1
Abstract:
The present invention can prevent the motion of the lumber or hip joints from being hindered while assisting a motion for stretching the lumber without using a pneumatic actuator or an electric actuator. In the present invention, lumber-part arms and thigh-part arms are coupled to each other in a revolvable manner along the plane of the thigh-part arms. When rope-like bodies provided to a lumber-part first arm and a thigh-part second arm are pulled in the extension direction by elastic members, the rope-like bodies and the elastic members stretch the lumber-part arms and the thigh-part arms. Further, the lumber-part first arm and a lumber-part second arm provided below the lumber-part first arm are coupled together with a lumber-part hinge provided so as to extend along end surfaces of the lumber-part first arm and the lumber-part second arm, and a thigh-part first arm and the thigh-part second arm provided below the thigh-part first arm are coupled together with a thigh-part hinge provided so as to substantially extend along a first direction substantially parallel with the lumber-part hinge.
