Abstract
An aircraft seat assembly for supporting a seat occupant, and a method for fabricating an aircraft seat assembly for supporting a seat occupant are provided. In one non-limiting example, the aircraft seat assembly includes a seat structure and a seat cushion that is supported by the seat structure. A vibration mitigating apparatus is operatively coupled to the seat structure to prevent or reduce vibrations from transferring to the seat occupant.
Claims15
An aircraft seat assembly for supporting a seat occupant, the aircraft seat assembly comprising:
- a seat structure;
- a seat cushion supported by the seat structure;
- and
- a vibration mitigating apparatus operatively coupled to the seat structure to one of reduce and prevent vibrations from transferring to the seat occupant, wherein the vibration mitigating apparatus is configured to one of actively cancel or reduce the vibrations by producing destructive interference vibrations that are out of phase with the vibrations, and wherein the aircraft seat assembly further comprises a controller that is in communication with the vibration mitigating apparatus and that is configured to receive an input signal and to generate a command signal in response to the input signal for instructing the vibration mitigating apparatus to produce the destructive interference vibrations.
An aircraft seat assembly for supporting a seat occupant, the aircraft seat assembly comprising:
- a seat base portion including a seat base structure portion and a seat base cushion supported by the seat base structure portion;
- a seat backrest portion coupled to the seat base portion and configured to extend substantially upright from the seat base portion, wherein the seat backrest portion includes a seat backrest structure portion and a seat backrest cushion supported by the seat backrest structure portion;
- and
- a vibration mitigating apparatus operatively coupled to one of the seat base structure portion and the seat backrest structure portion to one of reduce and prevent vibrations from transferring to the seat occupant, wherein the vibration mitigating apparatus is a first vibration mitigating apparatus configured to reduce the vibrations, and the aircraft seat assembly further comprises a second vibration mitigating apparatus configured to further reduce the vibrations, and wherein the second vibration mitigating apparatus is operatively coupled to one of the seat base structure portion and the seat backrest structure portion.
