Abstract
The passive exoskeleton “Chairless Chair” has been studied in the past for its practical use, but the true physiological benefits have not yet been thoroughly researched. Therefore, 17 subjects carried out, with and without the exoskeleton, three series of tests in the laboratory (treadmill ergometer, screwing and assembly tasks) in order to expand the knowledge about the benefits, but also about the limitations of the exoskeleton. Besides an objective stress and strain measurement, the physiological analysis was completed by the systematic interview of subjective strain perception. The subjective results show that the use of the exoskeleton during screwing and assembly work was perceived as beneficial. Walking on the treadmill, on the other hand, was viewed much more critically. The exoskeleton received negative ratings, especially with regard to posture and the feeling of safety. Many test persons therefore saw potential for improvement in the design as well as in some safety aspects.
