Abstract

The present disclosure relates to a seat ventilation system for deployment in a seat of a vehicle. Specifically, the seat ventilation system includes a three-dimensional mesh for maintenance of airflow channels and a ductless blower system to prevent system pressure loss. The air-permeable three-dimensional scaffold prevents compression and closure of pad-based airflow channels. The blower system reduces system air pressure loss by residing adjacent to the volume of interest, eliminating the need for ductwork.

First claim

The invention claimed is:

1. A ventilated seat, comprising:
an air-permeable seat pad cover;
a seat pad having a first surface, a second surface, and a void connecting the first surface with the second surface, the first surface being in fluid communication with the air-permeable seat pad cover;
a three-dimensional mesh of a pre-determined shape disposed within at least a portion of the void of the seat pad;
a first partition disposed on the second surface of the seat pad, the first partition having a full-thickness void in a pre-determined shape based on the pre-determined shape of the three-dimensional mesh;
a second partition, adjacent to the first partition, comprising an air-impermeable material and including at least one full-thickness void, the second partition being a pressed material having a first layer and a second layer; and
a ductless blower in fluid communication with the second partition,
wherein the first layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof, and
wherein the second layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof.

2. The ventilated seat of claim 1 , wherein the three-dimensional mesh is comprised of a flexible, incompressible material that maintains a structure of the void of the seat pad.

3. The ventilated seat of claim 1 , wherein the ventilated seat is a seat cushion, a seat back, or a combination thereof.

4. The ventilated seat of claim 3 , wherein the seat cushion comprises at least one gasket that joins sequential components of the seat cushion.

5. The ventilated seat of claim 1 , wherein the first partition is a pre-formed backing material comprised of a polymer, a synthetic textile, a textile, or a combination thereof.

6. The ventilated seat of claim 1 , wherein
a contour of the first layer of the pressed material matches a contour of the second surface of the seat pad, and
a contour of the second layer of the pressed material matches a contour of a cushion pan in fluid communication with the first partition and the ductless blower.

7. The ventilated seat of claim 1 , wherein a mesh structure of the three-dimensional mesh directs air flow.

8. The ventilated seat of claim 1 , wherein the first partition is a backing material comprised of a polymer, a synthetic textile, a textile, or a combination thereof.

9. The ventilated seat of claim 1 , wherein a contour of the first layer of the pressed material matches a contour of the second surface of the seat pad.

10. The ventilated seat of claim 1 , wherein the ductless blower is configured to pull air or push air.

11. A seat pad assembly, comprising:
a seat pad having a first surface, a second surface on an opposite face, and a void connecting the first surface with the second surface;
a three-dimensional mesh of a pre-determined shape disposed within at least a portion of the void of the seat pad;
a first partition of a pre-determined thickness disposed on the second surface of the seat pad, the first partition having a full-thickness void in a pre-determined shape based on the pre-determined shape of the three-dimensional mesh; and
a second partition, adjacent to the first partition, comprised of an air-impermeable material and including at least one full-thickness void, the second partition being a pressed material having a first layer and a second layer,
wherein the first layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof, and
wherein the second layer of the pressed material is a polymer, a metal, a synthetic textile, or a combination thereof.

12. The seat pad assembly of claim 11 , wherein the seat pad, the three-dimensional mesh, the first partition, and the second partition are sequentially disposed within the seat pad assembly.

13. The seat pad assembly of claim 11 , wherein the first partition is a backing material comprised of a polymer, a synthetic textile, a textile, or a combination thereof.

14. The seat pad assembly of claim 11 , wherein the first partition is a pre-formed backing material comprised of a polymer, a synthetic textile, a textile, or a combination thereof.

15. The seat pad assembly of claim 11 , wherein a mesh structure of the three-dimensional mesh directs air flow.

16. The ventilated seat of claim 1 , wherein the seat pad, the three-dimensional mesh, the first partition, the second partition, and the ductless blower are sequentially disposed within the ventilated seat.
