A window for automobiles or the like, including a frame member which is composed of a thermoplastic synthetic resin material and formed integrally with a window plate. The frame member includes a substantially U-shaped cross-sectional portion formed of lip and web sections which are spaced from and opposed to each other on outer and rear surfaces of the window plate, respectively, and connected with each other by a bridge section having a continuous hollow inner space therein. The frame member is formed by injecting into a mold cavity a relatively small amount, as compared with the volume of the mold cavity, of molten thermoplastic synthetic resin material, and by injecting compressed gas into the resin material to urge the resin material against inner surfaces of the mold defining the cavity.
Vitrage pour automobiles ou autres véhicules comprenant un élément de bâti en résine synthétique thermoplastique et formé intégralement avec une glace. Le bâti comprend des profilés en U composés d'une âme et d'ailes espacés les uns des autres et vis-à-vis les uns des autres sur les surfaces arrière et extérieures de la glace, respectivement, et raccordés les uns aux autres par une section de liaison renfermant un espace creux continu. L'élément de bâti est formé par injection, dans une cavité de moule, d'une quantité relativement faible de résine synthétique thermoplastique en fusion par rapport au volume de la cavité de moule,et par injection de gaz comprimé dans la résine afin de pousser la résine contre les surfaces internes de la cavité définissant le moule.
