DEVICE FOR REDUCING VIBRATIONS IN A HELICOPTER PILOT'S SEAT

摘要

The present invention relates to a device for reducing vibrations produced in the seat of helicopter pilots owing to the movement of the blades of said aircraft. Said device is based on a low-weight, low-cost pneumatic system that counteracts the vibrations experienced by the pilot while neutralizing the movement of the seat structure by causing the vibration to be absorbed by an air balloon and not transmitted to the pilot's body. In addition, the device has a support structure coupled to a safety and anchoring mechanism, which rests on the pneumatic bellows and moves vertically on the guides of the safety mechanism, thereby absorbing and insulating against the vibrations produced by the aircraft rotors.
