Abstract

An inflatable member includes a fluid delivery assembly positioned at intervals between an upper and a lower sheet. A plurality of fluid cells is defined by a series of ridges formed by a lower sheet of the inflatable member.

First claim

What is claimed is:

1. An inflatable member for a vehicle seating assembly comprising:
an upper sheet;
a lower sheet;
a fluid delivery assembly positioned at intervals between the upper and lower sheets, wherein the fluid delivery assembly is surrounded on at least two sides by the upper and lower sheets;
a plurality of fluid cells defined by a series of ridges formed by the lower sheet, wherein the series of ridges sealably couple to at least one of an underside of the fluid delivery assembly and the upper sheet in an air-tight manner, wherein the fluid delivery assembly corresponds with the series of ridges, and wherein the plurality of fluid cells are provided with fluid from the fluid delivery assembly; and
a support structure abutting an underside of the lower sheet, wherein the support structure includes a recess that receives the inflatable member, and wherein the inflatable member extends beyond the recess when inflated to a use condition.

2. The inflatable member for a vehicle seating assembly of claim 1 , wherein the fluid delivery assembly includes a network of check valves operably coupled to the plurality of fluid cells.

3. The inflatable member for a vehicle seating assembly of claim 2 , wherein the network of check valves are configured to control the pressure within the fluid cells.

4. The inflatable member of claim 1 , wherein the support structure is selected from the group consisting of a lower leg support, a seat, a seatback, and a headrest.

5. The inflatable member for a vehicle seating assembly of claim 4 , wherein the inflatable member extends beyond the recess in the support structure in vertical and lateral directions when inflated to the use condition.

6. The inflatable member for a vehicle seating assembly of claim 5 , wherein said inflatable member retracts in a curling fashion into the associated support structure when deflated from the use condition.

7. The inflatable member for a vehicle seating assembly of claim 1 , wherein the plurality of fluid cells are actively provided with a pressure by a fluid supply in fluid communication with the fluid delivery assembly.

8. The inflatable member for a vehicle seating assembly of claim 7 , wherein the fluid supply is an air compressor.

9. An inflatable member for a seating assembly comprising:
an upper sheet;
a lower sheet;
a fluid delivery assembly positioned at intervals and entirely between the upper and lower sheets;
a plurality of fluid cells defined by a series of ridges formed by the lower sheet, wherein the fluid delivery assembly corresponds with the series of ridges;
a support structure abutting an underside of the lower sheet; and
a recess in the support structure that receives the inflatable member, wherein the inflatable member extends beyond the recess when inflated to a use condition.

10. The inflatable member for a seating assembly of claim 9 , wherein the fluid delivery assembly includes a network of check valves operably coupled to the plurality of fluid cells.

11. The inflatable member for a seating assembly of claim 10 , wherein the network of check valves are configured to control the pressure within the fluid cells.

12. The inflatable member for a seating assembly of claim 9 , wherein the plurality of fluid cells are actively provided with a pressure by a fluid supply in fluid communication with the fluid delivery assembly.

13. The inflatable member for a seating assembly of claim 12 , wherein the fluid supply is an air compressor.

14. The inflatable member for a seating assembly of claim 9 , wherein the plurality of fluid cells are passively provided with a pressure by a plurality of bellows in fluid communication with the fluid delivery assembly.

15. An inflatable member comprising:
a fluid delivery assembly having capillary extrusions positioned at intervals between upper and lower sheets;
fluid cells defined by a series of ridges in the lower sheet and sealably coupled to at least one of the fluid delivery assembly and the upper sheet in an air-tight manner; and
a recess in a support structure that receives the inflatable member, the inflatable member extending beyond the recess when inflated.

16. The inflatable member of claim 15 , wherein the plurality of fluid cells are actively provided with a pressure by a fluid supply in fluid communication with the fluid delivery assembly.

17. The inflatable member of claim 15 , wherein the capillary extrusions are dual capillary extrusions.

18. The inflatable member of claim 15 , wherein the fluid delivery assembly includes a network of check valves operably coupled to the plurality of fluid cells.

19. The inflatable member of claim 18 , wherein the network of check valves includes a control valve configured to vent the pressure within the fluid delivery assembly in a controlled manner.
