Abstract

A vehicle seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend upwardly from the seat bottom. The seat back includes a seat-back frame and a comfort integrator unit to be mounted to the seat-back frame, as well as a seat-cover shell that can be positioned over the mounted comfort integrator unit.

First claim

The invention claimed is:

1. A seat back comprising:
a seat-back frame,
a comfort integrator unit configured to be secured to the seat-back frame, the comfort integrator unit including an integrator shell, a lumbar system coupled to the integrator shell to hang from cross-bars included in the integrator shell, and a comfort layer coupled to a passenger-receiving face of the integrator shell so as to locate the lumbar system between integrator shell and the comfort layer, and
a seat-cover shell including a passenger-receiving sculpted face and a rigid back face, joined together at a hinged top interface and configured to move between an open position in order to receive the seat-back frame and comfort integrator therein and a closed position to maintain the integrator shell, the lumbar system, and the comfort layer in a fixed position relative to the seat-back frame.

2. The seat back of claim 1 , further comprising a thermal component coupled to the comfort layer and located between the passenger-receiving sculpted face of the seat-cover shell and comfort layer.

3. The seat back of claim 2 , wherein the thermal comfort component is a resistive heat mat.

4. The seat back of claim 2 , wherein the thermal comfort component is a thermoelectric component comprising conductive material strips configured to provide both heating and cooling.

5. The seat back of claim 4 , wherein each conductive material strip includes an integrated thermal engine and heat exchanger configured to be affixed within openings formed in the comfort layer.

6. The seat back of claim 1 , wherein the hinge comprises a length of an interface between the passenger receiving sculpted face and the rigid back face sculpted seat cover shell further comprises a zipper extending laterally from each side of the hinge configured to maintain the seat-cover shell in the closed position.

7. The seat back of claim 1 , wherein the comfort integrator comprises integral side bolsters and the comfort integrator is made of a molded plastic material.

8. A method of assembling a seat back comprising:
providing a comfort integrator unit comprising at least a plastic comfort integrator, a comfort layer coupled to the plastic comfort integrator, and a lumbar system coupled therebetween,
coupling the comfort integrator unit to a vehicle seat-back frame, and
encasing the comfort integrator unit and the vehicle seat-back frame in a sculpted seat cover shell by pulling the shell over the comfort integrator unit and the vehicle component in a shell opened position, and
securing the shell in a closed position to establish the seat back.

9. The method of claim 8 , wherein the shell comprises a passenger receiving sculpted face and a rigid back face, joined together at a hinged top interface, and the shell is secured via zippers extending longitudinally from each end of the hinged top interface.

10. The method of claim 8 , wherein coupling the comfort integrator unit to the vehicle seat-back frame is performed robotically by automated insertion of fasteners into the vehicle seat back and the plastic comfort integrator.

11. The method of claim 8 , wherein the comfort integrator unit further comprises a thermal comfort component coupled to the comfort layer so that the thermal comfort component is positioned between the comfort layer and the passenger receiving sculpted face of the sculpted seat cover shell.

12. The method of claim 8 further comprising coupling a thermal comfort component to the comfort layer prior to coupling the comfort integrator unit to the vehicle seat-back frame.

13. The method of claim 12 , wherein the thermal comfort component is a resistive heat mat.

14. The method of claim 12 , wherein the thermal comfort component is a thermoelectric component comprising conductive material strips configured to provide both heating and cooling.

15. The method of claim 14 , wherein each conductive material strip includes an integrated thermal engine and heat exchanger configured to be affixed within openings formed in the comfort layer.

16. The method of claim 8 , wherein the comfort integrator unit further comprises a lumbar support system coupled between the comfort layer and the integrator shell.

17. A seat back comprising:
a seat-back frame,
a comfort integrator unit configured to be secured to the seat-back frame, the comfort integrator unit including an integrator shell and a comfort layer coupled to a passenger-receiving face of the integrator shell, and
a seat-cover shell including a passenger-receiving sculpted face and a rigid back face, joined together at a hinged top interface and configured to move between an open position in order to receive the seat-back frame and comfort integrator therein and a closed position to maintain the integrator shell, the lumbar system, and the comfort layer in a fixed position relative to the seat-back frame.

18. The seat back of claim 17 , wherein the comfort integrator unit further comprises a lumbar system coupled to the integrator shell to hang from cross-bars include in the integrator shell, so as to locate the lumbar system between integrator shell and the comfort layer.

19. The seat back of claim 17 , wherein the comfort integrator unit further comprises a thermal component coupled to the comfort layer and located between the passenger-receiving sculpted face of the seat-cover shell and comfort layer.

20. The seat back of claim 19 , wherein the thermal comfort component is a thermoelectric component comprising conductive material strips configured to provide both heating and cooling.
