Abstract

The present invention includes a ventilated seat for a vehicle having at least one ventilated component. The ventilated component has a cushion, a trim surface and an insert located beneath the trim surface of each ventilated component. The insert includes at least two layers, at least one of which is a molded layer. The at least two layer define an open space, that may include a spacer. The seat also includes an air mover assembly that is in fluid communication with the open space and servers to blow air to or draw air from the insert.

Claims

an air mover assembly in fluid communication with the open space.

2. The seat of claim 1 wherein the molded layer is a fluid barrier layer.

3. The seat of claim 1 wherein the molded layer is a flow control layer.

4. The seat of claim 1 further comprising a spacer material located between the first and second layers.

5. The seat of claim 1 wherein the insert further comprises and extension.

6. The seat of claim 1 further comprising a duct that extends through the cushion.

7. The seat of claim 6 wherein a bellows provides fluid communication between the air mover assembly and the insert.

8. The seat of claim 7 further comprising an air impermeable trim surface.

9. The seat of claim 7 further comprising an air permeable trim surface.

10. The seat of claim 9 wherein the air mover assembly comprises a plurality of fans.
