Abstract

Examples include an upper joint arm for engaging a wearer's upper torso, connected to a first positive-locking element, and include a lower joint arm for engaging the wearer's upper leg body, and have a force application lever with a second positive-locking element, and a a mechanical energy store between the force application lever and the second joint arm. The first and second positive-locking element are aligned on a common axis, and are axially movable for engagement and disengagement. A safety device provides, in a mechanical engaging of the first and second positive-locking element, a corrective rotating of one or both the positive-locking elements. This rotation adjusts initial misalignments of the first positive-locking element and the second positive-locking element. The first positive-locking element and second positive-locking element, when engaged, transfer swivelling of the first joint arm relative to the second joint arm into a charging-discharging of the mechanical energy store.
