## Abstract

A vehicle seating assembly includes a seating frame. A plurality of cellular supports include multiple base cells and multiple support cells. The multiple support cells are disposed directly above and include a different air pressure than the base cells. A diaphragm is proximate the base cells and the support cells. An air passage is defined through the diaphragm between adjacent cellular supports. An open air distribution layer extends over the cellular supports. A breathable coverstock extends over the distribution layer.

## Claims

### Claim 1

A vehicle seating assembly comprising:
a seating frame;
a plurality of cellular supports including:
multiple base cells; defined between a lower skin and an upper skin
multiple support cells defined between the upper skin and a generally flat diaphragm, the multiple support cells disposed directly above and including a different air pressure than the base cell wherein the lower skin wraps around side walls of the upper skin and substantially surrounds the support cells; and
an air passage defined through the diaphragm and between adjacent cellular supports;
an open air distribution layer above and adjacent to the diaphragm; and
a breathable coverstock extending over the distribution layer.

### Claim 2 (depends on 1)

The vehicle seating assembly of claim 1, wherein the support cells are pressurized to approximately 2 psi.

### Claim 3 (depends on 1)

The vehicle seating assembly of claim 1, wherein the diaphragm is disposed between the support cells and the open air distribution layer.

### Claim 4 (depends on 1)

The vehicle seating assembly of claim 1, wherein the support cells include a lower air pressure than the base cells.

### Claim 5 (depends on 1)

The vehicle seating assembly of claim 1, wherein air is drawn into a seat during a cooling operation and is blown from the seat during a heating operation.
