Une région arrière (20nb) située au niveau de la partie arrière longitudinale de l'absorbeur a une rigidité inférieure à celle d'une région avant (20na) située au niveau de la partie avant longitudinale de celui-ci. Concernant les lignes de pliage, la ligne de pliage la plus arrière (FLV1) située longitudinalement en arrière chevauche la région arrière, et la ligne de pliage la plus en avant (FLV3) située longitudinalement en avant chevauche la région avant. La partie de l'article absorbant sur le côté arrière de la ligne de pliage arrière est en contact avec une partie avant et se plie sur celle-ci. La rigidité de l'article absorbant est plus basse au niveau de la position de la ligne de pliage la plus arrière parmi les lignes de pliage.
