Abstract

The present invention provides an automotive vehicle seating comfort system, and method of forming thereof, for providing heating, cooling, ventilation or a combination thereof to an individual in an automotive car seat. In one configuration, the system includes an insert, a blower and a tubular structure for providing fluid communication between the insert and blower for providing ventilation and/or cooling for the individual. Additionally, in one preferred configuration, the insert includes a heater or heater layer for providing heat for the individual.

Claims (55)

1. A ventilation seat for a vehicle, comprising:

an air permeable outer trim layer;

a shaped foam body having an upper surface adjacent an occupant surface and a lower surface opposite the occupant surface, the foam body comprising part of a seat cushion or a seat back rest and located below the trim layer, the shaped foam body includes at least one airflow passageway extending through the shaped foam body between the upper surface to the lower surface;

an insert disposed between the shaped foam body and the trim layer, the insert including:

a spacer layer providing fluid flow between the at least one airflow passageway and the air permeable outer trim layer, and

at least one adhesive layer,

wherein the insert is adhered to the upper surface of the shaped foam body, and wherein the spacer layer is formed of a spacer material that has a top surface, a bottom surface and a side surface that is generally perpendicular to and connects the top and bottom surfaces and wherein the side surface is fluidly open;

an air mover in fluid communication with the shaped foam body, insert and trim layer; and

a tubular structure providing fluid communication between the air mover and the shaped foam body.

2. The seat of claim 1 , further comprising an insert support located over the airflow passageway.

3. The seat of claim 2 , wherein the insert support comprises a panel with through-holes extending therethrough.

4. The seat of claim 1 , further comprising a deflector placed over the at least one airflow passageway.

5. The seat of claim 1 , wherein the upper surface of the shaped foam body defines a recess for receiving the insert.

6. The seat of claim 1 , wherein the tubular structure extends at least partially through the shaped foam body.

7. The seat of claim 1 , wherein the air mover comprises a blower that is attached to the seat.

8. The seat of claim 1 , wherein the insert further includes a temperature sensor for sensing a temperature closely related to a temperature being experience by an occupant of the seat cushion or back rest.

9. The seat of claim 1 , further comprising a programmable controller for controlling the air mover.

10. A ventilation seat for a vehicle, comprising:

an air permeable outer trim layer;

a shaped foam body having an upper surface adjacent an occupant surface and a lower surface opposite the occupant surface, the foam body comprising part of a seat cushion or a seat back rest and located below the trim layer, the shaped foam body includes at least one airflow passageway extending through the shaped foam body between the upper surface to the lower surface;

an insert disposed between the shaped foam body and the trim layer, the insert including:

spacer layer providing fluid flow between the at least one airflow passageway and the air permeable outer trim layer, wherein the spacer layer comprises a polymeric strand material interwoven to provide opposing honey honeycomb structures, and

at least one adhesive layer,

wherein the insert is adhered to the upper surface of the shaped foam body;

an air mover in fluid communication with the shaped foam body, insert and trim layer; and

a tubular structure providing fluid communication between the air mover and the shaped foam body,

wherein the insert includes a generally vertical side surface that spans between a top and a bottom surface of the insert and which is fluidly open.

11. A ventilation seat for a vehicle, comprising:

an air permeable outer trim layer;

a shaped foam body having an upper surface defining a recess adjacent an occupant surface and a lower surface opposite the occupant surface, the foam body comprising part of a seat cushion or a seat back rest and located below the trim layer, the shaped foam body includes at least one airflow passageway extending through the shaped foam body between the upper surface to the lower surface;

an insert disposed in the recess and between the shaped foam body and the trim layer, the insert including:

a spacer layer providing fluid flow between the at least one airflow passageway and the air permeable outer trim layer, wherein the spacer layer comprises a polymeric strand material interwoven to provide opposing honey honeycomb structures, and

at least one adhesive layer,

wherein the insert is adhered to the upper surface of the shaped foam body and includes a generally vertical side surface that spans between a top and a bottom surface of the insert and sides which is fluidly open;

a heater for providing warmth to an occupant of the seat cushion or back rest;

a temperature sensor for sensing a temperature closely related to a temperature being experience by an occupant of the seat cushion or back rest;

an insert support located over the airflow passageway, the insert support comprising a panel with through-holes extending therethrough

a deflector placed over the at least one airflow passageway;

a blower mounted to the seat and being in fluid communication with the shaped foam body, insert and trim layer;

a tubular structure extending at least partially through the shaped foam body, the tubular structure providing fluid communication between the air mover and the shaped foam body; and

a programmable controller for controlling functions of the heater and blower.

12. A ventilation seat for a vehicle, comprising:

an air permeable outer trim layer;

a shaped foam body having an upper surface adjacent an occupant surface and a lower surface opposite the occupant surface, the foam body comprising part of a seat cushion or a seat back rest and located below the trim layer, the shaped foam body includes at least one airflow passageway extending through the shaped foam body;

an insert disposed between the shaped foam body and the trim layer, the insert including:

spacer layer providing fluid flow between the at least one airflow passageway and the air permeable outer trim layer, wherein the spacer layer comprises a polymeric strand material interwoven to provide opposing honey honeycomb structures, and

a heater layer for providing heat to an occupant of the seat cushion or set back rest, the heater layer located adjacent the spacer layer,

at least one adhesive layer for bonding the spacer layer and the heater layer,

wherein the insert is adhered to the upper surface of the shaped foam body, and wherein the spacer layer is formed of a spacer material that includes a generally vertical side surface that spans between a top and a bottom surface of the spacer layer and the side surface is open at its sides to allow fluid flow therethrough; and

an air mover in fluid communication with the insert and trim layer.

13. The seat of claim 12 , wherein the heater comprises a lay-wire heater or a carbon fiber heater.

14. The seat of claim 12 , wherein the insert includes sides which are fluidly open.

15. The seat of claim 12 , further comprising a tubular structure extending at least partially through the shaped foam body to fluidly connect the air mover and the insert.

16. The seat of claim 12 , wherein the insert further includes a temperature sensor for sensing a temperature closely related to a temperature being experienced by an occupant of the seat cushion or back rest.

17. The seat of claim 12 , further comprising a programmable controller for controlling the air mover and the heater layer.
