Abstract

An air-delivery system, for use in a vehicle. The system includes a backrest of a vehicle seat assembly and an air-delivery port connected to or integral to the backrest. The system also includes an input conduit connected to the air-delivery port for delivering air received from an air source to the air-delivery port. The air-delivery port is configured and arranged in the backrest facing a generally aft direction to, during operation of the system, deliver air received from the air source aftward from the backrest.

First claim

What is claimed is:

1. An air-delivery system, for fostering a customized microclimate for a rear passenger of a vehicle, comprising:
a backrest of a vehicle seat assembly;
an air-delivery port constituent to the backrest; and
an input conduit connected to the air-delivery port for delivering air received from an air source to the air-delivery port;
wherein the air-delivery port is directed in a generally aft direction of the backrest to, for comfort of the rear passenger in use of the system, deliver air received from the air source aftward from the backrest.

2. The system of claim 1 wherein the air-delivery port is adjustable by way of automated controls.

3. The system of claim 1 further comprising an intermediate air pump connected to the input conduit, downstream of a primary air pump, when the system is installed in the vehicle.

4. The system of claim 1 wherein:
the air-delivery port is a first air-delivery port;
the first air-delivery port is part of an air-delivery apparatus comprising also a second air-delivery port; and
the first air-delivery port is positioned above the second air-delivery port in the air-delivery apparatus.

5. The system of claim 1 wherein:
the air source comprises:
a thermoelectric (TE) device; and
a main vehicle heating, ventilating, and air conditioning (HVAC) source connected also to vehicle HVAC openings distinct from the air-delivery port; and

the system further comprises at least one sub-system selected from a group consisting of:
a user-system interface configured and arranged to, in operation of the system, allow selective vehicle-user control of an amount of air received at the air-delivery port from the main HVAC source versus an amount of air received at the air-delivery port from the TE device; and
an automated sub-system configured and arranged in the system to, in operation of the system, control an amount of air received at the air-delivery port from the main HVAC source versus an amount of air received at the air-delivery port from the TE device.

6. An air-delivery system, for fostering a customized microclimate for a rear passenger of a vehicle, comprising:
a backrest of a vehicle seat assembly; and
an air-delivery port constituent to the backrest and directed in a generally aft direction of the backrest to, for comfort of the rear passenger in use of the system, deliver aftward, from the backrest, air received at the air-delivery port.

7. An air-delivery system, for fostering a customized microclimate for a rear passenger of a vehicle, comprising:
an air-delivery port configured to be constituent to a backrest of a vehicle seat assembly and directed in a generally aft direction of the backrest to, for comfort of the rear passenger, deliver air received from an air source aftward from the backrest; and
an input conduit connected to the port for delivering air from the air source to the air-delivery port.

8. The system of claim 7 further comprising the backrest.

9. The system of claim 7 wherein the air-delivery port is adjustable by way of automated controls.

10. The system of claim 7 further comprising the air source, the air source including a thermoelectric device positioned within the vehicle seat assembly.

11. The system of claim 7 further comprising an intermediate air pump, for connection and operation downstream of a primary heating, ventilating, and air-conditioning air pump.

12. The system of claim 7 , wherein:
the air-delivery port is a first air-delivery port;
the first air-delivery port is part of an air-delivery apparatus comprising also a second air-delivery port; and
the first air-delivery port is positioned above the second air-delivery port in the air-delivery apparatus.

13. The system of claim 12 wherein the first air-delivery port is configured and arranged to direct air from the air-delivery apparatus toward an upper portion of the passenger and the second air-delivery port is configured and arranged to direct air from the air-delivery apparatus directly toward a lower portion of the passenger, below the upper portion.

14. The system of claim 12 wherein each of the first air-delivery port and the second air-delivery port is adjustable by way of automated controls.

15. The system of claim 7 further comprising a user-system interface configured and arranged to allow control of one or both of an amount and a temperature of air delivered from the air-delivery port.

16. The system of claim 7 wherein:
the air source comprises a main heating, ventilating, and air conditioning (HVAC) source connected also to vehicle HVAC openings distinct from the air-delivery port; and
the input conduit connects to the HVAC source behind a vehicle cabin surface.

17. The system of claim 16 wherein:
the air source comprises a thermoelectric (TE) device; and
the system comprises a user-system interface configured and arranged to, in operation of the system, allow selective vehicle-user control of an amount of air received at the air-delivery port from the main HVAC source versus an amount of air received at the air-delivery port from the TE device.

18. The system of claim 16 wherein:
the air source comprises a thermoelectric (TE) device; and
the system comprises an automated sub-system configured and arranged in the system to, in operation of the system, control an amount of air received at the air-delivery port from the main HVAC source versus received at the air-delivery port from the TE device.

19. The system of claim 1 wherein:
the air source comprises a main heating, ventilating, and air conditioning (HVAC) source connected also to vehicle HVAC openings distinct from the air-delivery port; and
the input conduit connects to the HVAC source behind a vehicle cabin surface.

20. The system of claim 6 wherein:
the air-delivery port is a first air-delivery port;
the first air-delivery port is part of an air-delivery apparatus comprising also a second air-delivery port; and
the first air-delivery port is positioned above the second air-delivery port in the air-delivery apparatus.

21. The system of claim 20 wherein the first air-delivery port is configured and arranged to direct air from the air-delivery apparatus toward an upper portion of the passenger and the second air-delivery port is configured and arranged to direct air from the air-delivery apparatus directly toward a lower portion of the passenger, below the upper portion.

22. The system of claim 4 wherein the first air-delivery port is configured and arranged to direct air from the air-delivery apparatus toward an upper portion of the passenger and the second air-delivery port is configured and arranged to direct air from the air-delivery apparatus directly toward a lower portion of the passenger, below the upper portion.
