## 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 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 diaphragm, the multiple support cells disposed above and including a lower air pressure than an air pressure of the base cells, wherein the lower skin substantially wraps the support cells; and
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 seating assembly of claim 1, wherein the support cells are pressurized to approximately 2 psi.

### Claim 3 (depends on 1)

The 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 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.

### Claim 5 (depends on 1)

The seating assembly of claim 1, wherein the plurality of cellular supports extends over a top surface and side surfaces of a vehicle seat; and
the breathable coverstock extends over the upper skin.

### Claim 6 (depends on 5)

The seating assembly of claim 5, wherein the plurality of cellular supports are pressurized to approximately 2 psi.

### Claim 7 (depends on 5)

The seating assembly of claim 5, wherein the lower skin wraps around at the upper skin.

### Claim 8 (depends on 7)

The seating assembly of claim 7, wherein the lower skin wraps the upper skin and around at least one of the plurality of cellular supports defined between the upper skin and the lower skin.

### Claim 9 (depends on 5)

The seating assembly of claim 5, further comprising:
a recess defined between the breathable coverstock and the upper skin, wherein the open air distribution layer extends over the plurality of cellular supports.

### Claim 10 (depends on 9)

The seating assembly of claim 9, wherein the open air distribution layer is disposed in the recess.
