Abstract: An exoskeleton for supporting an arm of a user includes a torso attachment device for releasably connecting the exoskeleton to a torso of the user, 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, and a spring element. A force is exertable on the cantilever and the lifting rod by the spring element.

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.

Abstract: A device for providing a supporting force for a user's upper extremity. The device includes a supporting device, an arm strut, a rotary joint that connects the supporting device to the arm strut, a spring element that provides the supporting force where the supporting force is provided in a first mode and a second mode, a connecting element where the spring element is disposed between the supporting device and the connecting element, and a force transmission element that has a first end and a second end and is guidable about the connecting element. The first end is attached to a first suspension point on the supporting device in the first mode and the second end is attached to a second suspension point on the arm strut in the first mode. The first and second ends are attached to the second suspension point in the second mode.

The ratchet mechanism connects a first end of the lifting rod to a first end of the cantilever where the ratchet mechanism allows rotation of the cantilever in a first direction of rotation and blocks rotation of the cantilever in a second direction of rotation.

Abstract: A device for supporting and relieving a load on an arm of a user includes an upper subregion, a lower subregion, and a joint that has a horizontal axis of rotation where the upper subregion and the lower subregion are connected by the joint such that the upper subregion is pivotable in an upper spatial direction and a lower spatial direction about the horizontal axis of rotation of the joint. The joint is pivotable in the upper spatial direction and the lower spatial direction in a first state and is pivotable only in the upper spatial direction in a second state.
