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.

Claims

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.
