Abstract

Claims (43)

1. A seat support, comprising:

a substrate of a non-foam material mounted to a seat frame, wherein the substrate comprises a plurality of functional components; and

a plurality of layers of a non-foam material mounted to the substrate and to support an occupant upon the seat frame, wherein the plurality of layers comprises:

a base layer mounted above the substrate, and

a second layer mounted above the base layer,

wherein the base layer has a first firmness, and the second layer has a second firmness that is less firm than the first firmness, and

wherein the plurality of layers is stacked upon each other, and at least one of the plurality of layers has a generally uniform thickness.

2. The seat support of claim 1 , wherein the base layer has a first thickness, and

wherein the second layer has a second thickness that is less than the first thickness.

3. The seat support of claim 1 , wherein the base layer is formed from a monofilament textile material.

4. The seat support of claim 1 , wherein the second layer is formed from a monofilament textile material.

5. The seat support of claim 1 , wherein the second layer is formed from polyester.

6. The seat support of claim 1 , wherein the second layer is one of welded, sewn, or adhered to the base layer.

7. A seat assembly, comprising:

the seat support of claim 1 ; and

a trim cover sized to receive the seat support with the second layer that is oriented between the trim cover and the base layer.

8. The seat support of claim 1 , further comprising a plurality of zones, wherein at least two zones of the plurality of zones vary in thickness, or firmness.

9. The seat support of claim 8 , wherein the plurality of zones further comprises a nose, an insert, and a pair of bolsters on opposed lateral sides of the nose and the insert to support a seat bottom.

10. The seat support of claim 8 , wherein the plurality of zones further comprises an insert, a pair of bolsters on opposed lateral sides of the insert, and a pair of shoulders on opposed lateral sides of the insert to support a seat back.

11. A method for manufacturing a seat assembly, comprising:

forming a substrate of a non-foam monofilament material comprising a plurality of functional components;

forming a base seat support portion of a non-foam monofilament material;

cutting a second seat support portion from a sheet of non-foam monofilament material;

installing the second seat support portion upon the base seat support portion;

attaching the base seat support portion above the substrate; and

installing the substrate to a seat frame of the seat assembly.

12. The method of claim 11 , further comprising installing a trim cover over the base seat support portion and the second seat support portion so that the second seat support portion is oriented between the base seat support portion and the trim cover.

13. The method of claim 11 , further comprising fastening the second seat support portion to the base seat support portion.

14. A seat assembly manufactured according to the method of claim 11 .

15. A method for manufacturing a seat assembly, comprising:

forming a substrate of a non-foam monofilament material comprising a plurality of functional components;

forming a base seat support portion from a non-foam material;

cutting a second seat support portion from a sheet of monofilament material;

installing the second seat support portion upon the base seat support portion;

fastening the second seat support portion to the base seat support portion;

attaching the base seat support portion above the substrate;

installing the substrate upon a seat frame of the seat assembly; and

installing a trim cover over the base seat support portion and the second seat support portion so that the second seat support portion is oriented between the base seat support portion and the trim cover.

16. The seat support of claim 1 , wherein the plurality of layers is defined in a combination that supports a comfort curve profile for the seat support.

17. The method of claim 12 , further comprising installing an intermediate pad layer between the trim cover and the second seat support portion.

18. The seat support of claim 1 , wherein the plurality of functional components comprises one of air bladders, a cooling assembly, or a ventilation port.

19. The seat support of claim 1 , wherein the substrate includes a first surface and a second surface, where the base layer is mounted to the first surface of the substrate, and the second surface that is opposite to the first surface conforms to an overall shape and contour of the seat frame.

20. The seat support of claim 1 , wherein the substrate is formed from a recycled material.
