ABSTRACT:
An inflatable pneumatic enclosure 1 of constrained geometric shape, comprising two main walls 2, 3 held the one relative to the other, in the inflated state of the enclosure, in a pre-specified relative position by a multiplicity of flexible links 4 interposed between said walls 2, 3, an inflation valve 6 being fixed in one of said walls 2 for the inflation of the enclosure, characterised in that the valve 6 is of the embedded or semi-embedded type with a valve body 7 extending inside the enclosure 1 under said mounting wall 2 and in that a spacing body 8 extends between the valve body 7 and the opposite wall 3 of the enclosure and is fixed to these, said spacing body 8 being dimensioned so that the two aforementioned walls 2, 3 are held in a desired relative position in relation to that obtained by the surrounding flexible links.
