Abstract

A vehicle seating assembly is provided that includes a seatback and a support layer coupled to a seat frame. The support layer includes a plurality of sealed support cells and defines a plurality of attachment points. The support cells have a first air pressure and a comfort layer positioned over the support layer. The comfort layer includes a plurality of sealed comfort cells having a second air pressure. The support layer, comfort layer, and cover stock are secured to the seat frame via the attachment points.

First claim

What is claimed is:

1. A vehicle seating assembly, comprising:
a seatback;
a support layer coupled to a seat frame, the support layer comprising a plurality of permanently closed support cells and defining a plurality of attachment points, wherein the support cells have a first air pressure;
a comfort layer positioned over the support layer, the comfort layer comprising a plurality of permanently closed comfort cells having a second air pressure; and
a cover stock positioned over the comfort layer, wherein the support layer, comfort layer, and cover stock are secured to the seat frame via the attachment points.

2. The vehicle seating assembly of claim 1 , wherein the support cells are connected via a support webbing and the comfort cells are connected via a comfort webbing, the comfort webbing in physical contact with the cover stock.

3. The vehicle seating assembly of claim 2 , wherein the support webbing defines a plurality of ventilation slots between the support cells and the comfort webbing defines a plurality of ventilation apertures between the comfort cells.

4. The vehicle seating assembly of claim 3 , wherein the ventilation slots and the ventilation apertures are in fluid communication with the cover stock.

5. The vehicle seating assembly of claim 1 , wherein the first air pressure is greater than the second air pressure.

6. The vehicle seating assembly of claim 1 , wherein at least one of the plurality of support cells and the plurality of comfort cells are in a grid arrangement.

7. The vehicle seating assembly of claim 1 , wherein the support layer and the comfort layer are each positioned within the seatback.

8. A seating assembly, comprising:
a seatback;
a support layer coupled to a seat frame, the support layer comprising a plurality of support cells, wherein the support cells have a first air pressure; and
a comfort layer positioned on top of the support layer, the comfort layer comprising a plurality of comfort cells having a second air pressure,
wherein at least two comfort cells couple to bend the comfort layer around the support layers.

9. The seating assembly of claim 8 , wherein the support cells are connected via a support webbing and the comfort cells are connected via a comfort webbing, the comfort webbing in physical contact with a cover stock.

10. The seating assembly of claim 8 , wherein the support layer and the comfort layer are positioned within a seat bottom of the seating assembly.

11. The seating assembly of claim 8 , wherein the support layer and the comfort layer are positioned within the seatback of the seating assembly.

13. The seating assembly of claim 8 , wherein the support layer defines a plurality of ventilation slots in fluid communication with a cover stock.

14. A vehicle cushion assembly, comprising:
a support layer coupled to a seat frame comprising a dosed support cell and defining a ventilation slot; and
a comfort layer positioned on top of the support layer, the comfort layer comprising a comfort cell and defining a ventilation aperture,
wherein the ventilation slot and aperture are in fluid communication with a cover stock and the comfort layer wraps over a top and a side surface of the support layer.

15. The vehicle cushion assembly of claim 14 , wherein the support layer includes a support webbing and the comfort layer has a comfort webbing, the comfort webbing in physical contact with the cover stock.

16. The vehicle cushion assembly of claim 14 , wherein the support cell has a higher resting air pressure than the comfort cell.

17. The vehicle cushion assembly of claim 14 , wherein the cushion assembly is coupled to a seatback of a vehicle seating assembly.

18. The vehicle cushion assembly of claim 17 , wherein the cushion assembly defines a seat bottom of a vehicle seating assembly.
