Support shell arrangement

Abstract

A support shell assembly (1) comprises a calf part (2), a foot part (3), and a locking device (5) with a guide rail (52) and with a locking element (51). The locking element (51) is displaceable along the guide rail (52) for setting a bending angle (α) between calf part (2) and foot part (3). The locking device (5) also comprises a spring element (53) which applies a spring force to the locking element (51) in such a way that displacement along the guide rail (52) is made easier or more difficult. An inlay (7) for a support shell assembly comprises a first chamber (71) and a second chamber (72). By means of a first and second valve device (73, 74), a fluid can be filled into the first chamber or discharged from the second chamber to stiffen the inlay (7) in a respective area.
