Abstract

L'invention concerne une couche de type bandes (1) destinée à un nourrisson de faible poids et possédant une longueur de direction longitudinale maximale inférieure ou égale à 330 mm. La couche de type bandes comprend, sur son premier côté dans la direction longitudinale, une paire de rabats latéraux (20) à laquelle des bandes de fixation (40) sont fixées, et comprend une paire de parties de fronces tridimensionnelles (50). Les parties de fronces tridimensionnelles (50) comprennent chacune : un élément élastique (51); une paire de parties de base (52) qui sont situées aux deux extrémités dans la direction longitudinale et qui ne sont pas aptes à se tenir verticalement dans la direction d'épaisseur; et une partie verticale (54) qui est apte à se tenir verticalement vers un côté de peau dans la direction d'épaisseur. Par rapport à la direction longitudinale, des extrémités de second côté des parties de base (52) qui sont sur le premier côté sont alignées sur des extrémités de second côté des bandes de fixation (40) ou sont positionnées davantage vers le second côté que les extrémités de second côté des bandes de fixation (40). Les éléments élastiques (51) présentent un facteur d'étirement de 1,5 à 2,0 fois.
