Abstract (en)
[origin: WO9007890A1] Controlled-rigidity support element, in particular, for a seat consisting of a sealed cover (29) and a filler (30), characterized in that the filler (30) is in the form of a flexible laminated structure, the various layers (31; 32, 33; 32a, 32b, 34) of which are mounted with relative displacement, under the effect of a non-uniform distribution of the filler compression force in the absence of any control-pressure. The cover (29) is subjected to a change in pressure in order to prevent any relative displacement of siad layers (31; 32, 33; 32a, 32b, 34), while giving them the necessary rigidity.
