Abstract

An exoskeleton for supporting an arm of a user includes a torso attachment device, a bracket which is connectable to the torso attachment device, a lifting rod which is connectable to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket, a cantilever for supporting the arm of the user which is releasably connectable to the arm of the user, a ratchet mechanism that connects a first end of the lifting rod to a first end of the cantilever, and a blocking device. The ratchet mechanism is adjustable by the blocking device from a release position into a blocking position where, in the release position, the cantilever is pivotable relative to the lifting rod and where, in the blocking position, a pivoting movement of the cantilever relative to the lifting rod is blocked.
