Orthopaedic seat-back (1) for subjects affected by dystonia and the like, apt to accompany, and restrain, the involuntary movements of the subject, having an articulated structure, to make the seat-back assume a plurality of configurations, corresponding to bending and/or torsion stresses exerted by the subject thereon, in which the articulated structure comprises elastic return means (3, 4; 300, 400), arranged at each articulation thereof, to oppose the exerted stress and restore the seat-back to an unrelated resting configuration when the exerted stress is substantially nil. |
