Une couche jetable (10) comprend : un corps absorbant (11) ; une ceinture (80) comportant une région d'extension et de contraction de bande (R80) qui est située du côté de la surface de la peau par rapport à une feuille côté surface de la peau dans une région de tronc arrière et qui s'étend et se contracte dans le sens de la largeur ; et une partie rabat présentant une région d'articulation (75) jointe au corps absorbant, une région d'extension et de contraction de rabat (76), et une section de verrouillage (73). La ceinture comprend : une première partie d'extrémité de base (87) et une seconde partie d'extrémité de base (84) jointe à la feuille côté surface de la peau ; et une partie verticale (85) repliée vers le côté arrière sur une ligne pliée (FL) sur le côté avant par rapport à la première partie d'extrémité de base (87) et à la seconde partie d'extrémité de base (84). La partie rabat est au moins partiellement disposée entre la feuille côté surface de la peau et la ceinture. Le bord extérieur de la ceinture est disposé dans une région chevauchant la région d'articulation.
