Abstract

A seat assembly includes a seatback having a cushioned component pivotally coupled to the seatback and operable between deployed and retracted positions. The cushioned component includes an interior cavity. A rack assembly is positioned within the interior cavity and includes a forward-most rack with a first receiving area. The rack assembly further includes a rearward-most rack having a second receiving area. A first cartridge assembly is removeably received in the first receiving area of the rack assembly. A second cartridge assembly is removeably received in the second receiving area of the rack assembly. The rack assembly may also include one or more intermediate rack assemblies positioned between the forward-most and rearward-most rack assemblies for supporting other intermediate cartridge assemblies. Each cartridge assembly includes a different density profile for providing variated comfort settings to the seatback of the seat assembly.

First claim

What is claimed is:

1. A seat assembly, comprising:
a cushioned component having an interior cavity;
a rack assembly positioned within the interior cavity, wherein the rack assembly includes a plurality of racks disposed therein, and further wherein each rack of the plurality of racks includes opposed first and second mounting members spaced-apart from one another to define a receiving area therebetween; and
a plurality of cartridge assemblies removeably received on the rack assembly, wherein each cartridge assembly of the plurality of cartridge assemblies includes a cushioned portion having first and second attachment interfaces disposed on opposite sides of the cushioned portion, and further wherein the first and second attachment interfaces of each cartridge assembly of the plurality of cartridge assemblies are slideably received in a corresponding rack of the plurality of racks of the rack assembly along the opposed first and second mounting members.

2. The seat assembly of claim 1 , wherein the first and second attachment interfaces of each cartridge assembly of the plurality of cartridge assemblies include one or more rails outwardly extending from the opposite sides of the cushioned portion.

3. The seat assembly of claim 2 , wherein the opposed first and second mounting members of each rack of the plurality of racks include one or more channels inwardly opening towards the receiving area.

4. The seat assembly of claim 3 , wherein the one or more rails are slideably received in the one or more channels.

5. The seat assembly of claim 1 , wherein the cushioned portion of each cartridge assembly of the plurality of cartridge assemblies includes a lattice matrix having a density profile.

6. The seat assembly of claim 5 , wherein the cushioned portion of each cartridge assembly of the plurality of cartridge assemblies includes a lattice matrix of interconnected links having a density profile.

7. The seat assembly of claim 6 , wherein the cushioned portion and the first and second attachment interfaces are comprised of a common material to define a monolithic structure.

8. The seat assembly of claim 1 , wherein the cushioned component includes a cover surrounding the interior cavity.

9. The seat assembly of claim 8 , wherein the cover includes an articulating flap that removeably covers an open top portion of the cushioned component to selectively provide access to the interior cavity.

10. A seat assembly, comprising:
a cushioned component having an interior cavity;
a rack assembly positioned within the interior cavity, wherein the rack assembly includes first and second mounting members spaced-apart from one another to define a receiving area therebetween, and further wherein the first and second mounting members each include first and second channels disposed therealong that open inwardly towards the receiving area; and
a cartridge assembly having first and second attachment interfaces spaced-apart from one another and interconnected by a cushioned portion, wherein the first and second attachment interfaces each include first and second rails spaced apart from one another and slideably received within the first and second channels of the first and second mounting members, respectively, and further wherein the cartridge assembly is removeably received within the receiving area.

11. The seat assembly of claim 10 , wherein the rack assembly includes first and second frame members having the first and second mounting members respectively mounted thereto.

12. A seat assembly, comprising:
a seatback having a cushioned component pivotally coupled to the seatback and operable between deployed and retracted positions, wherein the cushioned component includes an interior cavity;
a rack assembly positioned within the interior cavity and having a forward-most rack with a first receiving area, and further wherein the rack assembly includes a rearward-most rack having a second receiving area;
a first cartridge assembly removeably received in the first receiving area of the rack assembly; and
a second cartridge assembly removeably received in the second receiving area of the rack assembly.

13. The seat assembly of claim 12 , wherein the first cartridge assembly includes a cushioned portion having a first density profile, and further wherein the second cartridge assembly includes a cushioned portion having a second density profile that is different than the first density profile.

14. The seat assembly of claim 13 , including:
at least one intermediate rack disposed on the rack assembly between the forward-most rack and the rearward-most rack and having a receiving area.

15. The seat assembly of claim 14 , including:
a third cartridge assembly having a cushioned portion with a second density profile that is different than the first density profile of the first cartridge assembly and different than the second density profile of the second cartridge assembly, wherein the third cartridge assembly is removeably received in the receiving area of the at least one intermediate rack.

16. The seat assembly of claim 12 , wherein the first and second cartridge assemblies each include first and second attachment interfaces spaced-apart from one another, and further wherein the forward-most rack and the rearward-most rack each include opposed mounting members in which the respective first and second attachment interfaces of the first and second cartridge assemblies are slideably received.
