System for assisting an operator in exerting efforts

A system for assisting an operator in exerting efforts, the system comprising:

• a garment that can be worn by the operator, which is to engage, when worn, the mutually mobile parts of a joint of the operator, and is equipped with a mobile frame that defines at least one axis of rotation, which is to assume a position corresponding to the joint of the operator;
• and
• a compensation device carried by the garment and operable to compensate resistive moments acting on the joint during the effort exerted by the operator, the compensation device comprising:
• a first rotatable member and a second rotatable member, which are connected together and are brought into relative motion about a first axis of rotation as a result of movement of the joint of the operator, wherein the second rotatable member can rotate about a second axis of rotation;
• an elastic mechanism having at least one elastic element, is arranged for acting on the second rotatable member to impart on the first axis of rotation a moment opposite to the resistive moments;
• wherein the first and second rotatable members and the elastic mechanism are mutually prearranged in such a way that, in at least one pre-set position of the joint, the force exerted by the elastic mechanism on the second rotatable member is oriented in a direction incident with respect to the second axis of rotation of the second rotatable member.
