Abstract

There is disclosed a sealed edge insert suitable for placement within a seat of an automotive vehicle. The insert includes multiple layers, one of which includes a heater for providing an occupant of the seat with warmth. The insert also includes an air mover (e.g., a fan) for providing ventilation to the seat occupant. Further, the insert includes an extension that extends to a backside of a cushion component of the seat for attachment to provide fluid communication from the insert to the air mover.

Claims

1. A ventilated seat for a vehicle, comprising:

a vehicle seat having a backrest component which is ventilated, the backrest component having an air-permeable trim surface at the occupant contact areas of the seat and a cushion, wherein the cushion comprises at least one opening through the cushion;

a back support adjustment assembly including one or more wires that form a portion of a lumbar guide disposed within the backrest component;

an insert located between the trim surface and the cushion of the backrest component, wherein the insert comprises;

i) forward barrier layer and a rearward barrier layer made of an air impermeable material, wherein the forward barrier comprises a plurality of ventilation holes and the rearward barrier comprises at least one port; and

ii) a spacer material located between the barrier layers and defining an open space that permits fluid communication between the cushion and the trim surface of the ventilated component, wherein the spacer material is less than coextensive with the barrier layers; and

a fan in fluid communication with the open space of the insert through the opening in the cushion, wherein the fan is attached to the one or more wires that form a portion of the lumbar guide;

wherein the spacer material is a polymeric strand material interwoven with a opposing honeycomb structure and interconnected by several additional polymeric strand materials to provide an open space.

2. The ventilated seat of claim 1 wherein the insert is substantially coextensive with the cushion.

3. The ventilated seat of claim 1 wherein the insert is less than coextensive with the cushion.

4. The ventilated seat of claim 3 wherein the barrier layers are sealed together using heat to soften or melt the barrier layers.

5. The ventilated seat of claim 3 wherein the barrier layers are sealed together with an adhesive.

6. The ventilated seat of claim 1 wherein the fan both blows air toward the seat occupant or draws air away from the seat occupant.

7. The ventilated seat of claim 1 wherein the fan includes a c-shaped clip configured for forming an interference fit to the one or more wires that form the portion of the lumbar guide.

8. The ventilated seat of claim 1 wherein the insert further comprises a heater sub layer integrated therein.

9. A ventilated seat for a vehicle, comprising:

a vehicle seat having a backrest component which is ventilated, the backrest component having an air-permeable trim surface at the occupant contact areas of the seat and a cushion wherein the cushion comprises at least one opening through the cushion;

an insert located between the trim surface and the cushion of each ventilated component, wherein the insert comprises;

i) forward barrier layer and a rearward barrier layer made of an air impermeable material where the barrier layers are open along a peripheral edge, wherein the forward barrier comprises a plurality of ventilation holes and the rearward barrier comprises at least one port;

ii) a spacer material located between the barrier layers and defining an open space that permits fluid communication between the cushion and the trim surface of the ventilated component, wherein the spacer material is less than coextensive with the barrier layers and includes a polymeric strand material that is interwoven to provide opposing honeycomb structures; and

iii) a heater, supported with a backing, integrated into the insert; and

a fan in fluid communication with the open space of the insert through the opening in the cushion, wherein the fan is attached to one or more wires that form a portion of a lumbar guide of a back support adjustment assembly.

10. The ventilated seat of claim 9 wherein the fan includes a c-shaped clip configured for forming an interference fit to the one or more wires that form the portion of the lumbar guide.

11. The ventilated seat of claim 9, including at least one temperature sensor disposed near the trim surface or the insert for sensing a temperature closely related to the temperature being experienced by an individual in the seat.

12. A ventilated seat, comprising:

a seat having a seat component and a backrest component, at least one of which is ventilated, each ventilated component having an air-permeable trim surface at the occupant contact areas of the seat and a cushion, wherein the cushion comprises a plurality of openings through the cushion;

an insert located between the trim surface and the cushion of each ventilated component, the insert comprising an integrated heater, a topside barrier layer, an underside barrier layer and a spacer material comprising a polymeric strand material that defines an open space that provides fluid communication between a first opening in the underside barrier layer and a plurality of second openings in the topside barrier layer of the insert, wherein the polymeric strand material interwoven with a opposing honeycomb structure and interconnected by several additional polymeric strand materials; and

an air mover in fluid communication with the open space of the insert through the plurality of openings in the cushion wherein the air mover is attached to a mounting structure of a back support adjustment assembly.

13. The ventilated seat of claim 12 wherein the insert is sealed on at least one of its sides.

14. The ventilated seat of claim 13 wherein the seat further comprises a temperature sensor in signaling communication with a control unit.

15. The ventilated seat of claim 14 wherein the control unit controls the air mover, the integrated heater or both to attain or maintain a desired temperature at areas adjacent the seat occupant or the temperature sensor.

16. The ventilated seat of claim 12 wherein barrier layers are attached to each other using an adhesive or welding.

17. The ventilated seat of claim 12 wherein the integrated heater comprises a flexible electrical heating element.
