Abstract

La présente invention se rapporte à une fermeture à glissière (10). Dans ladite fermeture, un arrêt supérieur (11) est fixé à une demi-chaîne de fermeture gauche ou droite (1). L'arrêt supérieur (11) comprend un premier arrêt supérieur (12, 12') qui est en contact avec l'extrémité côté épaule d'une glissière (20), et un second arrêt supérieur (13, 13') qui est disposé entre le premier arrêt supérieur (12, 12') et une rangée d'éléments (3) et qui maintient l'état arrêté de la glissière (20). La taille maximale dans le sens de la largeur de bande depuis le bord de contact de la glissière (13c) jusqu'au bord côté opposé du second arrêt supérieur (13, 13') est conçue pour être plus importante que la largeur d'insertion entre le pôle de guidage (25) et le rebord (26) de la glissière (20), et au moins une partie du second arrêt supérieur (13, 13') est configurée pour être élastiquement transformable de manière à être contractée dans le sens de la largeur de bande. Par conséquent, la glissière (20) peut être arrêtée par le premier arrêt supérieur (12, 12') et l'état arrêté de la glissière (20) peut être maintenu de façon stable par le second arrêt supérieur (13, 13').
