| Abstract: |
In a cellular element the individual cells (1) are connected via a narrowed passage (2) to another cell or to a duct (3), which can be connected via a valve to a first pressure source. Hollow, expansible bodies (4) of an elastic, yielding material are placed in the duct and/or in one or more cells (1). The bodies (4) are interconnected via one or more yielding organs (5) in such a way that when they expand, they prevent outflow from the cells (1). The yielding organ or organs (5) may appropriately be tubes connecting the interior of the expansible bodies (4) with a second pressure source. An expansible body (4) may be placed in each cell (1), and the yielding organ or organs (5) is/are then shaped and dimensioned in such a way that when the body (4) is expanded, it bears against the mouth of the passage (2) into the cell (1) and tightens it.

I claim:
1. A cellular assembly comprising a first network of inflation cells interconnected by first conduit means to a first inflation duct, each cell having an inlet-outlet aperture communicating with the first conduit means, and a second network of individual inflation bodies contained within the respective cells for closing the respective inlet-outlet apertures when the bodies are expanded and opening the respective apertures when the bodies are contracted, the bodies being interconnected by second conduit means contained within the first conduit means to a second inflation duct within the first inflation duct.
