Abstract
A motion assistance apparatus including a support link to be attached to a waist of a user, a thigh link connected to a first end of the support link, a knee link connected to a first end of the thigh link, a connecting link connected to a first end of the knee link, and selectively connected to a second end of the support link, and an actuator configured to rotate the knee link with respect to the thigh link is provided.
Claims19
A motion assistance apparatus, comprising:
- a support link configured to attach to a waist of a user, the support link including a first end and a second end;
- a thigh link connected to the first end of the support link;
- a knee link connected to the thigh link;
- a connecting link connected to the knee link, the connecting link configured to be selectively connected to the second end of the support link such that the connecting link is configured to,
- assist a hip joint motion of the user by performing a 4-bar linkage motion together with the thigh link, the knee link, and the support link, when the connecting link is connected to the support link, and
- assist a knee joint motion of the user, when the connecting link is disconnected from the support link;
