Abstract

A vehicle seating assembly includes a frame. A cushion assembly includes a plurality of closed base cells disposed on the frame. Each base cell includes a fixed volume of fluid disposed therein. A plurality of trim cells are disposed on the base cells and include a variable volume of fluid disposed therein. The trim cells are in communication with a fluid pump. A coverstock is disposed over the trim cells. The trim cells further define a plurality of apertures configured to communicate air between a climate control system and a seating surface of the coverstock.

Claims

1. A vehicle seating assembly comprising:

a frame;

a seat cushion assembly comprising;

a plurality of closed base cells disposed on the frame, each base cell having a fixed volume of fluid disposed therein;

a plurality of trim cells disposed on the base cells and having a variable volume of fluid disposed therein, the trim cells being in communication with a fluid pump; and

a coverstock disposed over the trim cells, the trim cells further defining a plurality of apertures configured to communicate air between a climate control system and a seating surface of the coverstock.

2. The vehicle seating assembly of claim 1, further comprising:

an anti jounce cell disposed below the plurality of closed base cells.

3. The vehicle seating assembly of claim 1, wherein the plurality of apertures are in communication with elongate channels that extend through the plurality of trim cells.

4. The vehicle seating assembly of claim of claim 1, further comprising:

surface grooves disposed on a top surface of the plurality of trim cells, the surface grooves being in communication with the plurality of apertures.

5. The vehicle seating assembly of claim 1, wherein the plurality of trim cells are also in communication with one another.

6. The vehicle seating assembly of claim 1, wherein the plurality of closed base cells include intermediate support members disposed therein.

7. The vehicle seating assembly of claim 1, wherein the plurality of closed base cells include forward base cells and rearward base cells, and wherein the rearward base cells have a greater depth than the forward base cells.

8. A cushion assembly for a vehicle seating assembly comprising:

a plurality of closed base cells;

an anti jounce cell disposed below the base cells proximate a rear portion of the cushion assembly;

a plurality of open trim cells disposed on the base cells and in communication with a fluid pump; and

a coverstock disposed over the trim cells, the trim cells further including ventilation apertures in communication with a seating surface of the coverstock.

9. The cushion assembly of claim 8, wherein the anti jounce cell is disposed in a seat portion of the cushion assembly proximate a rear portion of the seat portion.

10. The cushion assembly of claim 8, wherein the anti jounce cell includes an arcuate configuration.

11. The cushion assembly of claim 8, wherein the ventilation apertures are in communication with elongate channels that extend through the plurality of open trim cells.

12. The cushion assembly of claim 8, further comprising:

surface grooves disposed on a top surface of the plurality of open trim cells, the surface grooves being in communication with the ventilation apertures.

13. The cushion assembly of claim 8, wherein the plurality of open trim cells are also in communication with one another.

14. The cushion assembly of claim 8, wherein the plurality of closed base cells include intermediate support members disposed therein.

15. The cushion assembly of claim 8, wherein the plurality of closed base cells include forward base cells and rearward base cells, and wherein the rearward base cells have a greater depth than the forward base cells.

16. A cushion assembly for a vehicle seating assembly comprising:

a plurality of closed base cells disposed on a frame, each base cell having a fixed volume of fluid disposed therein;

a plurality of open trim cells disposed on the base cells and in communication with a fluid pump; and

a coverstock disposed over the trim cells, the trim cells further including ventilation apertures configured to move air proximate a seating surface of the coverstock.

17. The cushion assembly of claim 16, further comprising:

an anti jounce cell disposed below the plurality of closed base cells.

18. The cushion assembly of claim 17, wherein the anti jounce cell is disposed in a seat portion of the cushion assembly proximate a rear portion of the seat portion.

19. The cushion assembly of claim 16, wherein the ventilation apertures are in communication with elongate channels that extend through the plurality of open trim cells.

20. The cushion assembly of claim 16, further comprising:

surface grooves disposed on a top surface of the plurality of open trim cells, the surface grooves being in communication with the ventilation apertures.
