Abstract: A rotational joint of intra-extra rotation for assistance of the movement of intra-extra rotation of a shoulder of a user. The rotational joint features a first circular guide arranged to rotate about a first rotation axis and a second circular guide arranged to rotate about a second rotation axis that is parallel to the first rotation axis. A support element is arranged to support the first and the second circular guides. The first and the second circular guide are pivotally connected by a conical wheel having a third rotation axis perpendicular to the first rotation axes and said conical wheel being pivotally constrained to the support element.

Abstract: The object of the present invention is a new configuration of torsional spring with a flat structure, capable of ensuring response linearity, modelling ease and accuracy, versatile use while safeguarding the possibility of the inner passage of wiring or of any accessory components along the transmission/torsion axis.

Abstract: A kinematic chain comprises a first pulley, arranged to rotate about a rotation axis x, and a second pulley arranged to rotate about a rotation axis y. The kinematic chain comprises then at least one connecting element comprising at least one passage having at least one rotating element, said or each connecting element also comprising at least one interface arranged to connect the connecting element to an adjacent connecting element or to a pulley, generating a rotational constraint about a rotation axis z.
