Because the front window glass of a car is usually in the shape of a ladder, the moving body 50 must make an arc movement in space during the movement.

Abstract

L'invention concerne un mécanisme de support d'un pare-soleil mobile comprenant des glissières cylindriques et des ouvertures latérales s'étendant sans interruption tout au long des glissières ; une pluralité d'éléments de support, chacun présentant une tête de support de forme pratiquement arrondie couplée dans le creux de chaque glissière et un bras de connexion assemblant les têtes de support en série et reliant celles-ci sur le bras de connexion ; et un mécanisme de traction sur lequel sont fixées les têtes de support. Lors de la traction, le corps mobile reposant sur les éléments de support coulisse le long de la glissière. Ce mécanisme peut être utilisé avec un pare-soleil associé au pare-brise avant d'un véhicule, un écran de porte courbée et un écran de fenêtre courbée.
