Abstract

La présente invention concerne un curseur (6, 7) destiné à une fermeture à glissière comprenant un corps de curseur (10) qui a une plaque d'aile supérieure (40, 40a), une tirette (20, 20a), et un élément de recouvrement (30, 50). La tirette (20, 20a) comprend une section de languette (21), une section de raccordement (22) qui s'étend à partir de la section de languette (21), et une paire d'arbres de fixation (23) qui font saillie à partir d'une extrémité de la section de raccordement (22) sur les côtés gauche et droit. L'élément de recouvrement (30, 50) comprend une première section de recouvrement (31a, 51a) qui recouvre une extrémité côté épaulement de la plaque d'aile supérieure (40, 40a) et une paire de deuxièmes sections de recouvrement (31b, 51b) qui s'étendent à partir de la première section de recouvrement (31a, 51a) vers un trou arrière. Grâce à cette configuration, même lorsqu'une force est reçue dans un sens qui amène la tirette (20, 20a) à se tordre, il est peu probable que la section de raccordement (22) de la tirette (20, 20a) se déforme ou casse. En outre, le curseur (6, 7) présente un toucher et un aspect agréables et d'autres articles et similaires ne sont pas susceptibles de s'accrocher sur le curseur (6, 7).
