Abstract

A seating assembly is provided that includes a seat base operably coupled with a seatback. An air cell assembly is positioned within the seat base. The air cell assembly includes a first plurality of air cells. The first plurality of air cells includes a first thigh cell. The air cell assembly also includes a second plurality of air cells. The second plurality of air cells includes a second thigh cell. A first valve is operably coupled with the first plurality of air cells. A second valve is operably coupled with the second plurality of air cells. Each of the first and second valves is configured to control airflow to and from the first and second plurality of air cells, respectively.

First claim

What is claimed is:

1. A seating assembly comprising:
a seat base operably coupled with a seatback;
an air cell assembly positioned within the seat base, the air cell assembly comprising:
a first plurality of air cells including a first thigh cell;
a second plurality of air cells including a second thigh cell;
a first valve operably coupled with the first plurality of air cells; and
a second valve operably coupled with the second plurality of air cells, wherein each of the first and second valves is configured to control airflow to and from the first and second plurality of air cells, respectively; and

a cable operably coupled to the first thigh cell and operably coupled with the seatback, the cable configured to selectively compress the first thigh cell.

2. The seating assembly of claim 1 , wherein the first and second plurality of air cells are each movable between an expanded state and a contracted state.

3. The seating assembly of claim 2 , wherein the first and second plurality of air cells include a fill material configured to bias the first and second plurality of air cells in the expanded state.

4. The seating assembly of claim 1 , wherein the seatback is operable between a raised position and a lowered position, and further wherein the cable biases the first thigh cell in a contracted state when the seatback is in the lowered position.

5. The seating assembly of claim 1 , wherein the first and second valves are coupled with the first and second plurality of air cells, respectively, by inlet tubes and exhaust tubes.

6. The seating assembly of claim 2 , wherein the first and second valves are in an open position when air cells of the first and second plurality of air cells move from the expanded state to the contracted state, and further wherein the first and second valves prevent airflow from the first and second plurality of air cells when the first and second valves are in a closed position.

7. A seating assembly comprising:
a seat base operably coupled with a seatback; and
an air cell assembly positioned within the seat base, the air cell assembly comprising:
a plurality of air cells including a thigh cell;
a valve operably coupled with the plurality of air cells;
a pump operably coupled with the plurality of air cells and the valve, wherein the valve is configured to control airflow from the pump to and from the plurality of air cells, and wherein the plurality of air cells includes a fill material configured to bias each of the plurality of air cells in an expanded state; and
a controller configured to detect an occupant and actuate the pump.

8. The seating assembly of claim 7 , wherein the valve is a three-way valve, and further wherein the pump is configured to provide airflow to and from the plurality of air cells through the valve.

9. The seating assembly of claim 8 , wherein airflow is inhibited when the valve is closed.

10. The seating assembly of claim 7 , wherein the plurality of air cells is one of multiple pluralities of air cells, and further wherein each of the multiple pluralities of air cells is independently expanded and contracted.

11. The seating assembly of claim 7 , further comprising:
a sensor configured to determine a height of a vehicle occupant, wherein the sensor provides input to the controller for providing a routine to the pump and valve for adjusting inflation of the plurality of air cells.

12. The seating assembly of claim 7 , further comprising:
a switch positioned proximate the seat base and configured to provide input to the controller for providing a routine to the pump and valve for adjusting inflation of the plurality of air cells.

13. A seating assembly comprising:
a seat base operably coupled with a seatback;
a first plurality of air cells positioned within the seat base;
a second plurality of air cells positioned within the seat base, wherein each of the first plurality of air cells and the second plurality of air cells is movable between an expanded state and a contracted state;
a first valve operably coupled with the first plurality of air cells;
a second valve operably coupled with the second plurality of air cells, wherein each of the first and second valves is configured to control airflow to and from the first and second plurality of air cells, respectively;
a first pump operably coupled with the first valve and configured to provide inflow and outflow of air through the first valve; and
a second pump operably coupled with the second valve and configured to provide inflow and outflow of air through the second valve.

14. The seating assembly of claim 13 , wherein each of the first and second valves is operably coupled within an inlet and exhaust of one of the first and second plurality of air cells, respectively.

15. The seating assembly of claim 13 , further comprising:
a controller operably coupled with one of the first valve and the second valve;
a sensor configured to determine a size of an occupant, wherein the sensor provides input to the controller for providing a routine to the respective valve for allowing inflation of the plurality of air cells.

16. The seating assembly of claim 13 , further comprising:
a controller operably coupled with one of the first valve and the second valve;
a switch positioned proximate the seat base, wherein the switch provides input to the controller for providing a routine to the respective valve for allowing inflation of the plurality of air cells.

17. The seating assembly of claim 13 , wherein each air cell of the first and second plurality of air cells includes a self-expanding fill material configured to bias each air cell in the expanded state.

18. The seating assembly of claim 17 , wherein a weight of an occupant provides an external pressure to compress the fill material and expel air from the respective air cell.
