Abstract

L'invention concerne un élément formant joint étanchéité supérieur 10 comportant d'un seul tenant une section de montage 11 et une section faisant saillie 12 en forme de plaque. La section de montage 11 présente une coupe transversale en forme de U dans laquelle une rainure d'insertion de panneau 16 qui est ouverte à l'avant est formée entre une section de paroi extérieure de joint d'étanchéité 13 et une section de paroi intérieure de joint d'étanchéité 14. Le rainure d'insertion de panneau 16 se déforme de manière élastique suite à l'insertion d'une section de bord supérieur de panneau 7 d'un panneau avant 4 dans la rainure d'insertion de panneau 16, depuis l'avant, et est ainsi maintenue par la section de bord supérieur de panneau 7. La section de paroi extérieure de joint d'étanchéité 13 et la section de paroi intérieure de joint d'étanchéité 14 se fixent fermement à la surface supérieure 7a et la surface inférieure 7b, respectivement, de la section de bord supérieur de panneau 7, et la section faisant saillie 12 se fixe de manière ferme à une surface de bord 3a d'une ouverture 3 d'un corps avant 2. La section faisant saillie 12 est inclinée obliquement vers l'avant depuis le côté section de paroi extérieure de joint d'étanchéité 13 jusqu'au côté pointe faisant saillie 12a, et l'épaisseur de la partie faisant saillie 12 s'effile progressivement vers le côté pointe faisant saillie 12a.
