VIBRATIONS REDUCTION DEVICE IN THE CHAIRS OF HELICOPTER PILOTS

摘要

The present invention refers to a device to reduce the vibrations that are produced in the chairs of helicopter pilots due to the movement of the blades of such aircraft. Such device is based on a low weight and cost pneumatic system, that counteracts the vibrations suffered by the pilot, as it neutralizes the movement of the chair's structure making the vibration to be absorbed by a pneumatic ball and is not transmitted to the pilots body. Additionally, the device counts with a support structure coupled to a security mechanism and anchorage, which rests over the pneumatic bellows and vertically displaces over the security mechanism guides damping and isolating the vibrations produced by the aircraft's rotors.
