Abstract

L'invention concerne une fermeture à glissière comprenant : une première partie d'élément (22) dans laquelle un élément est situé sur un côté d'une bande dans le sens de l'épaisseur de la bande et ne peut pas être en prise avec un élément lui faisant face ; et une seconde partie d'élément (26) dans laquelle un élément est situé sur l'autre côté de la bande dans le sens de l'épaisseur de la bande et peut être mis en prise avec un élément lui faisant face. La seconde partie d'élément comprend : une seconde partie de base (27) fixée à la bande ; et une partie de mise en prise (28) qui fait saillie à partir de la seconde partie de base vers une bande lui faisant face et est en prise avec l'élément lui faisant face. La première partie d'élément comprend : une première partie de base (23) fixée à la bande ; et une première partie de saillie (24) qui fait saillie à partir de la première partie de base vers la bande lui faisant face et a une partie chevauchant la partie de mise en prise de l'élément lui faisant face dans le sens de l'épaisseur de la bande. Une butée comporte un corps de butée (40) qui relie deux bandes et s'étend dans la direction dans laquelle les deux bandes bandes se font face ; et une pièce de butée (45) faisant saillie dans le sens de la longueur des bandes à partir du corps de butée vers le second élément le plus proche du corps de butée. La pièce de butée comporte une première partie de pièce (46) située sur le côté de la première partie d'élément dans le sens de l'épaisseur des bandes ; et une seconde partie de pièce (47) située sur le côté de la seconde partie d'élément dans le sens de l'épaisseur des bandes.
