Abstract

La présente invention concerne un matériau de rembourrage qui peut être facilement monté et démonté dans la mesure où il n'y a pas d'augmentation du nombre de types de pièces et qui présente une plaque de séparation disposée de manière à ne pas être détachée par inadvertance après le montage du matériau de rembourrage. Des rainures (20) de cette plaque de séparation (10) répondent chacune à l'exigence "1/2 (hauteur h de plaque de séparation)" < "profondeur d1", et sont chacune pourvues de saillies (30) faisant saillie à l'intérieur de la rainure. Les saillies (30) font saillie de manière symétrique depuis les parois gauche et droite (23, 24) de manière à présenter des surfaces horizontales du côté fond de rainure (31) faisant saillie à un emplacement de la hauteur h1 qui est plus proche de l'ouverture que la moitié de [hauteur h de plaque de séparation] à partir du fond de la rainure. Des sections verticales (25, 26) présentant chacune une largeur b1 sensiblement égale à l'"épaisseur de plaque t de plaque de séparation" sont prévues entre les saillies et une ouverture. Une section entre les saillies et le fond de la rainure présente une largeur b2 de manière à ne pas faire saillie au-delà des lignes d'extension des sections verticales, et une profondeur d2 suffisamment grande pour loger les saillies (30). Des surfaces coniques s'ouvrant vers l'extérieur (27, 28) sont également formées au niveau du côté de l'ouverture.
