Abstract

L'invention concerne un curseur (1, 1a) comprenant : un corps de curseur (10, 10a) ; et un élément de fermeture (40, 40a) qui ferme un espace d'insertion (19) de tirette dans le corps de curseur (10, 10a). Une première partie en prise (20) et une seconde partie en prise (30, 30a) permettant de venir en prise avec l'élément de fermeture (40, 40a) sont disposées sur une plaque d'aile supérieure (11) et sur une partie d'extrémité libre (15b) d'une partie de fixation (15) de tirette. Une partie de régulation de verrouillage (33) verrouillant l'élément de fermeture (40, 40a) est disposée sur la première partie en prise (20) et/ou sur la seconde partie en prise (30, 30a). La première partie en prise (20) est disposée le long du sens de la longueur du curseur et comporte une partie de retenue d'élément (21) qui possède une section transversale en forme de T. Une position d'extrémité arrière d'une partie saillante (23) de la partie de retenue d'élément (21) se trouve devant une position d'extrémité arrière (L2) de la partie d'extrémité libre (15b) de la partie de fixation (15) de tirette. Par conséquent, la résistance de la plaque d'aile supérieure (11) peut être maintenue de manière stable, la structure d'un moule permettant de former le corps de curseur (10, 10a) peut être simplifiée, et une tirette (50) et l'élément de fermeture (40, 40a) peuvent être facilement attachés au corps de curseur (10, 10a).
