CA 2728667
The invention relates to a multi-chambered, fluid-fillable apparatus apparatus, comprising two sheets bonded together to define a plurality of cells between them. In a first aspect, at least one, and preferably both, of the sheets are formed from polyvinyl alcohol. In a second aspect, the sheets are sealed together using both permanent and non-permanent seals. The non-permanent seals are formed to rupture at a predetermined internal pressure in order to dissipate externally applied load.

Selon un premier aspect, au moins l'une des feuilles, et de préférence les deux, est/sont formée(s) d'alcool polyvinylique. Selon un second aspect, les feuilles sont assujetties l'une à l'autre au moyen de joints tant permanents que non permanents. Les joints non permanents sont prévus pour se rompre sous une pression interne déterminée afin de dissiper une force appliquée depuis l'extérieur.
