Abstract

Coussin gonflable (A) comportant une série de zones gonflables séparées (n, s, t, u) avec des conduits tubulaires (20, 21, 22, 23) partant de chaque zone (n, s, t, u), sous ou sur le coussin (A) à l'intérieur de la périphérie de ce dernier, et se rendant jusqu'à un distributeur commun (24) placé de manière à donner vers l'extérieur du bord avant du coussin. Le coussin est muni d'un tuyau de remplissage (25) raccordé au distributeur (24) et d'obturateurs (30) individuels ou de moyens pour bloquer les tubes de chaque conduit de sorte que les zones peuvent être gonflées et dégonflées simultanément ou séparément.
