Abstract

Selon la présente invention, la largeur d'un élément de fermeture (200) est déterminée par un premier plan virtuel (PL1) sur lequel est disposé un point, ou une surface, de chaque partie de mise en prise (210) positionnée sur le côté le plus à l'extérieur d'une bande de fermeture, et un second plan virtuel (PL2) sur lequel est disposé un point, ou une surface, de chaque partie de base (220) positionnée sur le côté le plus à l'intérieur de la bande de fermeture, le premier plan virtuel (PL1) et le second plan virtuel (PL2) étant parallèles l'un par rapport à l'autre. Une partie de mise en prise convexe (380), qui fait saillie au-delà du premier plan virtuel (PL1) vers l'extérieur de la bande de fermeture, ou une partie de mise en prise concave (390), qui est en retrait au-delà du premier plan virtuel (PL1) vers l'intérieur de la bande de fermeture, est disposée dans une zone arrière d'une première surface latérale (330) d'un arrêt avant (300). Une surface inclinée (345), qui s'étend de manière inclinée d'un côté à l'autre d'une zone avant jusqu'à une zone arrière d'une seconde surface latérale (340) de sorte à approcher le second plan virtuel (PL2), est incluse dans la seconde surface latérale (340) de l'arrêt avant (300).
