Abstract

Le présent modèle d'utilité propose un coussin gonflable à trois couches qui comprend trois couches de coussins d'air et qui se compose d'au moins cinq couches de tissus, qui sont, dans l'ordre : une couche supérieure, une première couche interne, une couche d'espacement, une seconde couche interne et une couche inférieure. Des trous traversants sont répartis uniformément sur la couche d'espacement. Des parties médianes de la première couche interne et de la seconde couche interne sont jointes au niveau des positions des trous traversants pour former des points d'articulation internes. Des parties médianes de la couche supérieure et de la première couche interne sont jointes à des positions non alignées avec les trous traversants pour former des points d'articulation supérieurs. Des parties médianes de la couche inférieure et de la seconde couche interne sont jointes à des positions non alignées avec les trous traversants pour former des points d'articulation inférieurs. Des parties périphériques de la couche supérieure, de la première couche interne, de la couche d'espacement, de la seconde couche interne et de la couche inférieure sont ajustées par pression, jointes et dotées de buses d'air. Le présent modèle d'utilité a trois couches de coussins d'air qui ont une bonne performance de rétention de chaleur et est pourvu d'une couche d'espacement qui a des trous traversants qui peut empêcher la couche supérieure et une autre couche ou la couche inférieure et une autre couche d'être assemblées par erreur pour former des points d'articulation lorsque la couche supérieure est jointe à la première couche interne et lorsque la couche inférieure est jointe à la seconde couche interne.
