Abstract:
1. An ergonomic device for supporting the body of an occupant, for a chair or a seat, wherein it comprises a supporting panel provided with a plurality of supporting laths set at a distance from one another, which are elastically deformable from a configuration of rest to an active configuration, deformed and/or displaced and/or arched with respect to the configuration of rest, and in that each lath is provided with at least one actuator designed to cause deformation and/or displacement thereof towards the aforesaid active condition, said actuator comprising an element constituted by a shape-memory material, which can undergo a reduction in length following upon a heating beyond a predetermined transition temperature higher than the ambient temperature, and there being associated to said panel electrical-supply means for supplying an electric current to each of said shape-memory actuators in order to activate it, and electronic control means for governing said electrical-supply means so as to activate independently and/or in succession and/or simultaneously said shape-memory actuators according to a predetermined logic.
