Support shell arrangement for arrangement at a lower leg

摘要

A support shell arrangement (20) is provided for arranging on a lower leg, having a foot part (23) and a calf part (21). The calf part includes two calf struts (29, 30) disposed at the side of an entry opening (32) of the calf part, extending in the longitudinal axis of the calf part, and a heel strut connected to the calf struts in a strut connection and extending toward a heel part of the foot part. A support bow arrangement (24) has two bow struts (34, 35) extending in a U-shape about a sole area, the free strut ends thereof being pivotally connected in pairs in a common pivot joint (43, 44) on a joint axis corresponding to the ankle joint and connected to a calf strut, and connected to each other in a V-shape by a common support basis (36). The support base is pivotally connected to the heel strut of the calf part at the heel side end thereof.
