Abstract

La présente invention se rapporte à une courroie à cliquet détachable et à un procédé de fabrication de cette dernière. De façon plus précise, dans une courroie détachable pour faire du sport, un élément métallique est inséré à l'intérieur de la courroie à cliquet détachable et une partie qui doit être couplée à la boucle d'un élément de fixation, est couplée à l'élément métallique qui est composé d'un matériau métallique de sorte à empêcher l'usure de la partie de la courroie à cliquet détachable qui est couplée à la boucle. De plus, l'élément métallique est prolongé et inséré à l'intérieur d'une partie de couplage de la courroie à cliquet détachable de sorte à empêcher des dégâts à la partie de mise en prise et à la partie de couplage de la courroie à cliquet détachable. En outre, selon le procédé de fabrication de la courroie à cliquet détachable, la partie de couplage de l'élément métallique est formée avec un trou circulaire de telle sorte que l'élément métallique puisse être fixé à un moule à injection pour éviter tout mouvement. Par conséquent, on empêche toute déformation au niveau de l'élément métallique malgré l'application de matériaux de moulage par injection à haute pression, ce qui permet de réduire la vitesse d'apparition de défauts.
