<p>The assembly (100) has a parallelepiped intermediate module (106) fixed between parallelepiped end modules (102, 104). Upper, intermediate and lower open bands (108, 110, 112) are distributed on height of the modules and made of flexible and non-extensible material e.g. PVC. Each band has two ends respectively fixed to the end modules. Each band passes from a front part of one of the modules to a rear part of the neighboring module or from a rear part of one of the modules to a front part of the neighboring module, where paths of the bands (108, 110) are reversed from one another.</p> |
