Abstract

Une structure d'acheminement de faisceau de fils achemine un faisceau de fils entre une carrosserie de véhicule et une portière, par une ouverture d'introduction. Cette structure d'acheminement de faisceau de fils est pourvue : d'un faisceau de fils ; d'un élément de revêtement externe tubulaire, qui recouvre le faisceau de fils ; d'un élément de fixation de carrosserie de véhicule, qui est fixé à une partie de l'élément de revêtement externe près d'une première extrémité de celui-ci, et est fixé à la carrosserie de véhicule ; d'un protecteur, qui est agencé à l'intérieur de la portière, comporte une ouverture d'introduction tubulaire dans laquelle est introduite la partie de l'élément de revêtement externe qui comprend l'autre extrémité de celui-ci, et qui loge le faisceau de fils, qui s'étend hors de l'autre extrémité de l'élément de revêtement externe introduit par l'ouverture d'introduction, dans un état tel qu'il y a un espace permettant au faisceau de tourner ; et d'un passe-fil qui comprend une section tubulaire qui st recouverte par l'ouverture d'introduction, et une section de protection qui a une forme plate le long de la direction orthogonale à l'axe central de la section tubulaire, possède une ouverture d'introduction débouchante par laquelle l'élément de revêtement externe introduit dans l'ouverture d'introduction peut être introduit, et qui recouvre l'intervalle situé entre l'ouverture d'introduction et l'élément de revêtement externe.
