DESCRIPTION:
BRIEF SUMMARY
The invention has as an object the realization of a composite opening element, such as a door or rear hatch or trunk lid of an automotive vehicle body, constituted by an association of metal and plastic material parts.
One knows of opening elements comprised of a panel constituted by a metal part such as a central sheet metal plate on which is molded a peripheral part of synthetic material, while there can be provided, coming directly from the operation of molding of the peripheral piece on the metal plate, stiffening ribs, elements of articulation of the opening element, or the points of attachment for example for the locks and the balancers. One such arrangement has the disadvantage that it does not provide the interior appearance and finish of the opening element.
The invention consists of an embodiment of an opening element of an automotive vehicle body having a one piece metal part of annular form and a one piece molded on plastic part forming the internal structural component of the opening element, the part of plastic providing the interior appearance and finish of the opening element.
Such an arrangement has the advantage of obtaining a homogeneous structural assembly and a perfect seal.
The invention relates thus to an opening element of an automotive vehicle body comprising particularly a panel constituted by a metal part, and a plastic part having stiffening ribs and molded onto the metal part, characterized in that the metal part and the plastic part constitute an internal structural component of the panel, an outside panel being attached to this internal structural component, and in that the metal part has an annular form of U section toward the interior in which are molded the stiffening ribs, these ribs being retained by the mounting points provided on the metal part.
According to another characteristic of the invention, the plastic part comprises a panel adapted to close the interior space of the metal part.
According to one preferred embodiment of the invention, the metal part has the form of a right angle trapezoid with an internal leg connecting the right angle adjacent the longer base to the opposite side.
According to another characteristic, an interior lining of thermoplastic material adapted to cover the shapes of the metal part is welded or bonded to the plastic part.
Other characteristics and advantages of the invention will be more apparent from the detailed description which follows and with reference to the accompanying drawings which give only an example, and in which:
FIG. 1 is an exploded view of the internal structural component of the lower panel of an opening element of an automotive vehicle body, such as a door;
FIG. 2 is an exploded view showing the mounting of the interior lining of the door on the internal structural component;
FIG. 3 is an exploded view showing the mounting of the outer panel of the door and the glass channel on the assembled internal interior-lining structure.
FIG. 1 shows exploded, the internal structure of an opening element such as a door constituted of an annular metal part 1 and a plastic material composite part 2, for example, of thermoplastic material reinforced with glass fibers. The metal part 1 of U section has essentially the shape of a right angle trapezoid with an internal leg 3 connecting the right angle of the longer base with the opposite side 3a, thus defining two openings 4 and 5. Such a shape allows taking into account the lines of force between the attachments of the door to the chassis (hinges and latch) namely: longitudinal compression, lateral intrusion, rigidity in torsion for the glass frame, and vertical rigidity. On the metal part is molded the plastic material composite 2 which has on one hand the stiffening ribs 6 retained in the interior of the metal part by points of mounting, and on the other hand the panels 7 and 8 adapted to close the openings 4 and 5 of the metal part. This provides in addition, a panel 9 disposed under the oblique side 3a of the metal part, and comprising an edge or rim 10 to form the bottom of a g
