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 cushion supported by the seat structure. A vibration producing apparatus configured to produce vibrations conducive for inducing drowsiness. The vibration producing apparatus is disposed adjacent to or within the seat structure for transferring the vibrations to the seat occupant.

First claim

What is claimed is:

1. 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 producing apparatus configured to produce vibrations, and wherein the vibration producing apparatus is disposed one of adjacent to and within the seat structure for transferring the vibrations to the seat occupant, wherein the seat structure includes a seat substructure that is configured to couple to a seat track, wherein the vibration producing apparatus is disposed within the seat substructure, and wherein the vibration producing apparatus is an audio speaker.

2. The aircraft seat assembly of claim 1 , wherein the vibrations have a frequency of from about 1 to about 15 Hz.

3. The aircraft seat assembly of claim 1 , wherein the vibrations have an amplitude of from about 0.005 inches to about 1 inch.

4. The aircraft seat assembly of claim 1 , further comprising a controller in communication with the vibration producing apparatus and configured to receive an input signal and to generate a command signal in response to the input signal for instructing the vibration producing apparatus to produce the vibrations.

5. The aircraft seat assembly of claim 4 , further comprising a control panel in communication with the controller and configured to receive an input from the seat occupant and to generate the input signal in response to the input.

6. The aircraft seat assembly of claim 4 , wherein the controller is configured to receive the input signal from one of a mobile device and an onboard network.

7. The aircraft seat assembly of claim 4 , further comprising an amplifier in communication with the controller and the vibration producing apparatus to receive the command signal and to produce a voltage and current in response to the command signal for communication to the vibration producing apparatus to produce the vibrations.

8. 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 producing apparatus configured to produce vibrations, and wherein the vibration producing apparatus is disposed one of adjacent to and within one of the seat base structure portion and the seat backrest structure portion for transferring the vibrations to the seat occupant, wherein the seat base structure portion includes a seat substructure that is configured to couple to a seat track, wherein the vibration producing apparatus is disposed within the seat substructure, and wherein the vibration producing apparatus is an audio speaker.

9. The aircraft seat assembly of claim 8 , wherein the vibration producing apparatus is a first vibration producing apparatus configured to produce the vibration as first vibrations, and the aircraft seat assembly further comprises a second vibration producing apparatus configured to produce second vibrations conducive for inducing drowsiness, and wherein the second vibration producing apparatus is disposed one of adjacent to and within the seat backrest structure portion for transferring the second vibrations to the seat occupant.

10. The aircraft seat assembly of claim 9 , wherein the second vibration producing apparatus is an additional audio speaker.

11. The aircraft seat assembly of claim 9 , further comprising a controller in communication with the first and second vibration producing apparatuses and configured to receive an input signal and to generate a first command signal and a second command signal in response to the input signal, wherein the first command signal instructs the first vibration producing apparatus to produce the first vibrations and the second command signal instructs the second vibration producing apparatus to produce the second vibrations.

12. A method for fabricating an aircraft seat assembly for supporting a seat occupant, the method comprising the steps of:
supporting a seat cushion by a seat structure, wherein the seat structure includes a seat substructure that is configured to couple to a seat track; and
incorporating a vibration producing apparatus into the aircraft seat assembly, wherein incorporating the vibration producing apparatus includes disposing the vibration producing apparatus within the seat substructure for transferring the vibrations to the seat occupant, and wherein the vibration producing apparatus is an audio speaker.
