The arrangement has two hinge parts (36, 38), where each of the hinge parts is strongly connected with a segment of a patient bearing surface. The hinge parts are pivotable against each other by a shaft extension (46) around a common hinge axis (64). The hinge parts are supported at one of the surfaces that are axially turned to each other, and are axially stretchable to each other by a blocking mechanism, where the surfaces are provided at an attachment of blocking surfaces (60). The blocking surfaces lie in a plane including the hinge axis. |
