Abstract
A vehicle seat includes a sealed inflation system having first and second inflation bladders interconnected by first and second supply lines for exchanging an inflation medium therebetween. Each inflation bladder includes one or more outwardly extending pilot stems. A first valve assembly is operably coupled to the pilot stems and first the supply line. Compression of the second inflation bladder opens the first valve assembly, and compression of the first inflation bladder closes the first valve assembly. A second valve assembly is disposed on the second supply and is configured to open and close as a seatback of the vehicle seat moves from a folded position to an upright position. The first and second valve assemblies are external components to the sealed inflation system.
