Claim Text:
1. A balancing system for a head of a passenger transported in a vehicle, in particular a helicopter or aircraft, comprising: a helmet configured to be fixed to the head of the passenger, suspension means for the helmet adapted to be connected to a structure of the vehicle and to the helmet so as to balance an imbalance of weights on a musculoskeletal system of a neck of the passenger wearing said helmet, said suspension means comprising a suspender, configured to be fixed to said structure, a telescopic overhanging element, having a first end and a second end, adapted to be positioned over the head of the passenger and, extending essentially horizontally on a plane substantially orthogonal to the suspender, a joint connecting the overhanging element to the helmet, a hinge connecting the first end of the overhanging element to the suspender, so that the second end can rotate on an essentially horizontal plane essentially orthogonal to the suspender, wherein said suspender is of the telescopic type, provided with a movable part adapted to impart an upward force to said telescopic overhanging element and, thus, to the helmet, in order to develop a balancing three of the weight of the helmet, wherein there is provided a pneumatic device for applying an upward bias to said movable part by means a first piston, wherein there is provided a pneumatic actuator with a second piston moveable and capable of varying the air pressure on the first piston, in order to adjust said upward bias, and wherein said telescopic overhanging element has a curvilinear shape, whereby said overhanging element, while extending telescopically, describes an arch on a plane comprising the suspender and the telescopic overhanging element, in order to reduce the volume occupied by the system.
