Abstract

Embodiments of radiant barriers for vehicles are disclosed. According to one embodiment, a vehicle includes an interior cabin at least partially enclosed by a roof panel, a floor panel, and an engine compartment firewall, and a radiant barrier positioned within the interior cabin. The radiant barrier includes a first thermally reflective surface and a second thermally reflective surface opposite the first thermally reflective surface and separated from the first thermally reflective surface by a thickness t. The thickness t is constant along a length and a width of the radiant barrier. The radiant barrier at least partially thermally isolates the interior cabin from an external environment.

First claim

What is claimed is:

1. A vehicle seat comprising:
a seat frame;
a pad supported by the seat frame;
a heater element positioned over the pad;
a radiant barrier positioned between the seat frame and the heater element, the radiant barrier comprising a substrate having at least a first thermally reflective surface on a first side of the substrate, the first thermally reflective surface positioned adjacent to the heater element; and
a seat cover positioned over the heater element and at least partially enclosing the radiant barrier, the heater element, and the pad, wherein the radiant barrier thermally reflects at least some heat from the heater element towards the seat cover.

2. The vehicle seat of claim 1 , wherein the radiant barrier is positioned between at least a portion of the pad and the heater element.

3. The vehicle seat of claim 2 , wherein the radiant barrier is disposed within the pad with at least a portion of the pad between the radiant barrier and the seat frame.

4. The vehicle seat of claim 1 , wherein the substrate further comprises a second thermally reflective surface on a second side of the substrate, wherein the first thermally reflective surface and the second thermally reflective surface are separated by a thickness t of the substrate, and wherein the thickness t is constant along a length and a width of the radiant barrier.

5. The vehicle seat of claim 1 , wherein the radiant barrier is positioned directly adjacent to the heater element.

6. The vehicle seat of claim 1 , wherein the radiant barrier is positioned between the seat frame and the pad.

7. The vehicle seat of claim 1 , wherein the radiant barrier is positioned between the heater element and the pad.

8. The vehicle seat of claim 1 , wherein the radiant barrier is incorporated into a tray configured to slide into and out of the vehicle seat.

9. The vehicle seat of claim 8 , wherein the seat frame comprises a slot configured to receive the tray.

10. The vehicle seat of claim 1 , wherein the vehicle seat comprises a seat portion and a back portion.

11. The vehicle seat of claim 10 , wherein the radiant barrier is positioned within the seat portion of the vehicle seat.

12. The vehicle seat of claim 10 , wherein the radiant barrier is positioned within the back portion of the vehicle seat.

13. A vehicle comprising:
at least one vehicle seat, the vehicle seat comprising:
a seat frame;
a pad supported by the seat frame;
a heater element positioned over the pad;
a radiant barrier positioned between the seat frame and the heater element, the radiant barrier comprising a substrate having at least a first thermally reflective surface on a first side of the substrate, the first thermally reflective surface positioned adjacent to the heater element; and
a seat cover positioned over the heater element and at least partially enclosing the radiant barrier, the heater element, and the pad, wherein the radiant barrier thermally reflects at least some heat from the heater element towards the seat cover.

14. The vehicle of claim 13 , wherein the radiant barrier is positioned between at least a portion of the pad and the heater element.

15. The vehicle of claim 14 , wherein the radiant barrier is disposed within the pad with at least a portion of the pad between the radiant barrier and the seat frame.

16. The vehicle of claim 13 , wherein the substrate further comprises a second thermally reflective surface on a second side of the substrate, wherein the first thermally reflective surface and the second thermally reflective surface are separated by a thickness t of the substrate, and wherein the thickness t is constant along a length and a width of the radiant barrier.

17. The vehicle of claim 13 , wherein the radiant barrier is positioned directly adjacent to the heater element.

18. The vehicle of claim 13 , wherein the radiant barrier is positioned between the seat frame and the pad.

19. The vehicle of claim 13 , wherein the radiant barrier is positioned between the heater element and the pad.

20. The vehicle of claim 13 , wherein the radiant barrier is incorporated into a tray configured to slide into and out of the vehicle seat.
