1. A device for supporting at least one arm of a user, wherein the device has
at least one arm support element with an arm shell for placing on the arm,
at least one passive actuator, which is configured to apply a force to the at least one arm support element, and
at least one counter bearing for the force to be applied, which comprises at least one force transmission element and a counter bearing element,
wherein the at least one arm support element is connected to the force transmission element via a joint such that the at least one arm support element can be swivelled about at least one swivel axis,
wherein application of the force to the at least one arm support element by the at least one passive actuator when the at least one arm of the user is raised such that an elbow of the user is above a shoulder of the user causes displacement of the arm shell along the at least one arm of the user toward a hand of the user,
characterized in that the device also comprises at least one restraining element that restricts the displacement of the arm shell along the arm towards the hand when the device is mounted and the at least one passive actuator applies the force to the at least one arm support element, but does not influence a displacement of the arm shell in the opposite direction, wherein the at least one restraining element is designed to be flexible yet inelastic.
