Dummy object with extremeties which utilise the mass inertia thereof to replicate a natural movement process

A dummy object comprising

• a torso,
• at least one extremity, which represents an arm or a leg, wherein the extremity comprises a proximal extremity portion, mounted in an articulated manner at the torso, and a distal extremity portion, mounted in an articulated manner at the proximal extremity portion,
• a joint between the proximal extremity portion and the distal extremity portion,
• a mechanical stop associated with the joint,
• at least one drive, which is arranged in the torso and which is designed to move the proximal extremity portion relative to the torso, and
• a holding mechanism comprising a magnetic element, the holding mechanism being associated with the joint between the proximal extremity portion and the distal extremity portion and which is constructed in such a manner that after an inversion of direction caused by the mechanical stop and a subsequent predetermined movement of the distal extremity portion in the reverse direction, a predetermined holding angle position is maintained between the proximal extremity portion and the distal extremity portion until a holding force of the holding mechanism is overcome by the inertia force of the distal extremity portion connected with a renewed inversion of direction,
• wherein the proximal extremity portion is movable in such a manner that a movement of the distal extremity portion, which is correlated with the movement of the proximal extremity portion, can be created by utilizing a mass inertia of the associated distal extremity portion.
