摘要：
A kinematical chain (100) for assisting a spherical motion of an anatomical joint (200) of a finger of the hand (210) of a user, said anatomical joint (200) having centre of rotation P and being arranged for allowing a relative motion of a finger of the hand (210) with respect to a portion of hand (220) of the user, said finger of the hand (210) defining a longitudinal direction δ. The kinematical chain (100) comprises a first rotational joint (110) engaged to the finger of the hand (210) and to a first connection link (115), said first rotational joint (110) arranged to provide a relative rotation α between the first connection link (115) and the finger of the hand (210) about a rotation axis ϰ coincident with the longitudinal direction δ. The kinematical chain (100) also comprises a third rotational joint (130) engaged to the portion of hand (220) and to a second connection link (125), said third rotational joint (130) arranged to provide a relative rotation γ between the second connection link (125) and the portion of hand (220) about a rotation axis z integral to the portion of hand (220). The kinematical chain (100) comprises then a second rotational joint (120) engaged to the first connection link (115) and to the second connection link (125), said second rotational joint (120) arranged to provide a relative rotation β between the first connection link (115) and the second connection link (125) about a rotation axis y. The rotation axes x, y and z intersect in a centre of rotation O, in such a way that the kinematical chain (100) allows a spherical motion of the longitudinal direction δ with respect to the portion of hand (220) about the centre of rotation P.La présente invention concerne une chaîne cinématique (100) permettant d'aider un mouvement sphérique d'une articulation anatomique (200) d'un doigt de la main (210) d'un utilisateur, ladite articulation anatomique (200) ayant un centre de rotation P et étant conçue pour permettre un mouvement relatif d'un
