Abstract
Second joints (7, 7) are provided in positions where a seating unit (1) is restrained from swinging relative to leg links (3, 3) due to a force acting on the seating unit (1) from upper limb links (5, 5) through the intermediary of the second joints (7, 7). A motion not intended by a user can be restrained from being generated due to a force acting from the upper limb links (5, 5) provided in the upper limbs.

A motion assist device, comprising:
- a weight supporting unit which supports a part of the weight of a user;
- a foot-worn unit to be attached to a foot of the user;
- a leg link which connects the foot-worn unit to the weight supporting unit;
- a first joint which connects the leg link to the weight supporting unit such that the leg link is free to swing at least in a longitudinal direction relative to the weight supporting unit;
- an upper-limb-worn unit to be attached to an upper limb of the user;
- an upper limb link which connects the upper-limb-worn unit to the weight supporting unit;
- a second joint which connects the upper limb link to the weight supporting unit such that the upper limb link is free to swing relative to the weight supporting unit;
- and
- a drive mechanism which drives a joint of the leg link,
- wherein the second joint is provided in a position where the weight supporting unit is restrained from swinging relative to the leg link due to a force acting on the weight supporting unit from the upper limb link through the intermediary of the second joint.
