Summary:For a vehicle door frame that has a door sash that forms a window opening and a beltline reinforcement that is extended along a beltline, a beltline reinforcement is constructed by fixing a first molded member, which is formed by means of extrusion-molding of a light metal, and a second molded member, which is formed by means of press-molding of a metal material, with the members being put together face-to-face in the thickness direction of the door in order to ensure the flexibility of the beltline reinforcement and the rigidity and strength thereof at the same time. Selon la présente invention, pour un cadre de portière de véhicule comprenant un châssis de guillotine de portière qui forme une ouverture de fenêtre et un renfort de ceinture qui s'étend le long d'une ceinture, un renfort de ceinture est construit en fixant un premier élément moulé, qui est formé au moyen d'un moulage par extrusion d'un métal léger, et un second élément moulé, qui est formé au moyen d'un moulage à la presse d'un métal, les éléments étant mis ensemble face-à-face dans la direction de l'épaisseur de la portière afin de garantir la flexibilité du renfort de ceinture ainsi que sa rigidité et sa résistance.
