Patent

CA 2527108

A cellular cushion includes a base, a plurality of hollow cells, and a sealing layer. The base includes at least a first layer and a second layer. The plurality of hollow cells are coupled to the base and extend outwardly from the base. Moreover, the plurality of cells are coupled together in- flow communication. The sealing layer is coupled to at least one of the base first and second layers. At least one of the sealing layer and the base defines a plurality of lock pockets, wherein each of the lock pockets is positioned between adjacent hollow cells for selectively controlling flow communication independently to each of the plurality of hollow cells within the cellular cushion.

L'invention concerne un coussin cellulaire comprenant une base, une pluralité de cellules creuses et une couche de scellement. La base comprend au moins une première couche et une deuxième couche. La pluralité de cellules creuses est couplée à la base et s'étend de la base vers l'extérieur. De plus, ces cellules sont couplées en communication fluidique. La couche de scellement est couplée à au moins la première ou la deuxième couche de base. Au moins la couche de scellement et la base définissent une pluralité de poches de blocage, chaque poche de blocage étant placée entre des cellules creuses adjacentes pour contrôler sélectivement la communication fluidique indépendamment de chaque cellule creuse de la pluralité de cellules du coussin cellulaire.
