Abstract

L'invention concerne un dispositif de store pour un véhicule automobile destiné à occulter une partie transparente d'un véhicule. Le dispositif de store comprend une bande de store (16), qui peut s'enrouler sur un arbre d'enroulement (20) pour former un store à rouleau et qui est guidée dans un rail de guidage (22A, 22B) au niveau de chacun de ses bords latéraux par référence à un plan vertical longitudinal médian du store, et un moyen d'entraînement muni d'un pignon d'entraînement (26) qui entraîne deux moyens de commande qui sont guidés chacun dans une glissière de guidage (30) d'un des rails de guidage (22A, 22B). Les moyens de commande sont conformés chacun en courroie dentée (28A, 28B) qui a une section transversale sensiblement rectangulaire et qui comporte sur au moins un côté une denture (32, 34). La bande de store (16) est comprimée entre le côté inférieur de la courroie dentée (28A, 28B) et un fond (42) du rail de guidage (30) et est déviée au moins approximativement en U par la courroie dentée (28A, 28B) dans le rail de guidage (30) lorsque l'on observe dans la direction transversale du rail de guidage ou est comprimé entre le côté supérieur de la courroie dentée (28A, 28B) et un plafond du rail de guidage (30) et est déviée au moins approximativement en U par la courroie dentée (28A, 28B) dans le rail de guidage (30) lorsque l'on observe dans la direction transversale du rail de guidage. L'arbre d'enroulement (20) comporte des deux côtés du plan médian longitudinal vertical du store une zone d'extrémité qui s'amincit en cône en direction du bord latéral respectif de la bande de store (16).
