Abstract

A ventilation assembly comprises a number of fan systems configured to purify air and a number of air distribution assemblies. Each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of a passenger seat. Each air distribution assembly of the number of air distribution assemblies comprises a pair of air distribution vents, ductwork configured to receive air from at least one fan system of the number of fan systems and direct air to the pair of air distribution vents, and a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback for providing purified air to a seated passenger.

First claim

What is claimed is:

1. A ventilation assembly that comprises:
a plate configured to removably connect directly to a seat track and directly to a fan system configured to also connect to a power outlet in a passenger seat, wherein the plate comprises a base and a positioning feature that extends orthogonally from the base; and
an air distribution assembly configured to be removably installed on a seatback of the passenger seat, wherein the air distribution assembly comprises:
a pair of air distribution vents;
ductwork configured to receive air from the fan system and direct air to the pair of air distribution vents; and
a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback.

2. The ventilation assembly of claim 1 , further comprising a second fan system connected to a second plate connected to the seat track.

3. The ventilation assembly of claim 1 further comprising:
a manifold configured to connect the fan system to the air distribution assembly, wherein the manifold is configured to receive output of the fan system, and wherein the manifold is configured to supply air to the air distribution assembly.

4. The ventilation assembly of claim 3 further comprising:
a second plate configured to attach to the seat track, the second plate comprises:
a base configured to join to a second fan system; and
the positioning feature is configured to restrain the manifold.

5. The ventilation assembly of claim 1 , wherein the plate comprises a base configured to join to the fan system.

6. The ventilation assembly of claim 1 , wherein the seat attachment device is configured to encircle a portion of the seatback to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback for providing purified air to a seated passenger.

7. The ventilation assembly of claim 1 , wherein the seat attachment device comprises one of elastic or a ratchet.

8. The ventilation assembly of claim 1 , wherein each fan system of is further configured to comprise a female power outlet.

9. The ventilation assembly of claim 1 , wherein the air distribution assembly is connected to the plate such that a weight of the air distribution assembly is supported by the plate.

10. The ventilation assembly of claim 1 , wherein the fan system comprises at least one of: UV sanitizing equipment, an electric filter, or a mechanical air filter.

11. The ventilation assembly of claim 1 , wherein the air distribution assembly is configured, to direct purified airflows from the pair of air distribution vents to converge and blend in front of a nose and mouth of a passenger and form a personal breathing space that envelopes an inhalation sphere suffused with a purified air comprises purified air.

12. A ventilation assembly that comprises:
a plate configured to removably connect directly to a seat track of an aircraft and directly to a fan system configured to also connect to a power outlet in a passenger seat of an aircraft, wherein the plate comprises a base and a positioning feature that extends orthogonally from the base;
a manifold configured to connect to the fan system and distribute air from the fan system to a number of air distribution assemblies, wherein each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of a passenger seat and comprises:
a pair of air distribution vents;
ductwork configured to direct air from the manifold to the air distribution vents; and
a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback and configured to provide purified air to an inhalation sphere at the passenger seat.

13. The ventilation assembly of claim 12 , wherein each fan system is further configured to comprise a female power outlet.

14. The ventilation assembly of claim 12 , wherein each air distribution assembly of the number of air distribution assemblies is connected to the plate such that a weight of the air distribution assembly is supported by the plate.

15. The ventilation assembly of claim 12 , wherein the fan system comprises at least one of: UV sanitizing equipment, an electric filter, or a mechanical air filter.

16. The ventilation assembly of claim 12 , wherein the seat attachment device comprises one of elastic or a ratchet.

17. The ventilation assembly of claim 12 , wherein the manifold comprises a number of flow restrictors configured to substantially equalize pressure and flow rate of an air supply from the manifold to each air distribution assembly.

18. A ventilation assembly that comprises:
a plate configured to removably connect directly to a track and directly to a fan system configured to also connect to a power outlet in a passenger seat, wherein the plate comprises a base and a positioning feature that extends orthogonally from the base
a manifold configured to distribute air from the fan system to a number of air distribution assemblies, wherein each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of the passenger seat.

19. The ventilation assembly of claim 18 , wherein the manifold comprises a number of flow restrictors configured to substantially equalize pressure and flow rate of the air supplied by the manifold to each air distribution assembly.

20. The ventilation assembly of claim 18 , wherein each air distribution assembly of the number of air distribution assemblies comprises:
a pair of air distribution vents;
ductwork configured to receive air from at least one fan system of the number of fan systems and direct air to the pair of air distribution vents; and
a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback and configured to provide purified air to an inhalation sphere at the passenger seat.

21. The ventilation assembly of claim 20 , wherein the seat attachment device is configured to encircle a portion of the seatback to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback and configured to provide purified air to an inhalation sphere at the passenger seat.

22. The ventilation assembly of claim 20 , wherein the seat attachment device comprises one of elastic or a ratchet.

23. The ventilation assembly of claim 18 , wherein each fan system is further configured to comprise a female power outlet.

24. The ventilation assembly of claim 18 , wherein an air distribution assembly of the number of air distribution assemblies is connected to the plate such that a weight of the air distribution assembly is supported by the plate.
