BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a support structure for a screen wiper mechanism.
More particularly, the invention relates to a support structure of the type comprising a plate which constitutes a support for various components of the mechanism, in particular for driving components of a screen wiper, and which includes means for fastening it onto a bodywork element of the vehicle, being also of the type comprising at least one structural element of elongate form, which is fixed to the support plate and which has a free terminal portion that carries for example a bearing for supporting a screen wiper drive spindle and/or complementary means for fastening the support structure on the body of the vehicle.
In accordance with a known design, which is for example described and shown in the document FR-A-2,621,287, the support plate is made in the form of a metal plate which is bent, press formed and reinforced by ribs, and of which a side edge portion is curved so as to define an open semi-cylindrical housing which receives a tubular portion, of complementary form, of the elongate structural element, which is for example made in the form of a bent and curved tube, the structural element being fixed to the curved edge portion of the metallic support plate by welding.
An opposite edge of the one-piece support plate has extensions or deformed portions which receive fastening elements, such as for example silentblocs.
The manufacture, and therefore the spatial configuration, of the metal support plate is particularly complex, because the fastening elements have to be arranged within the space in relatively precise positions which enable the support plate to be fastened on surrounding components of the bodywork of the vehicle.
In addition, the known one-piece design of the support plate makes it necessary to provide a specific support plate for each application, that is to say for each particular vehicle.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to propose a new design for a support structure of the type defined above, which overcomes the above mentioned drawbacks and which, in particular, enables the components of the support structure to be standardized while simplifying manufacture.
With this in view, the invention proposes a support structure characterized in that the support plate is made in the form of two superimposed plate elements, of which the first plate element is fixed to the structural element, the second plate element including the means for fastening the support structure on a bodywork element of the vehicle, and in that it includes means connecting the two plate elements together.
According to further features of the invention: means, in particular of the screw and nut type, for mounting a component for driving the screen wiper on the support plate, with the bodies of the assembly means extending through the two superimposed plate elements; the support structure through a set of assemblies of the screw and nut type, distributed around a hole which is formed in the two superimposed plates for passage therethrough of the output shaft of the motorized reduction gear unit; a lateral portion for fastening it on the structural element; as at least partly to match the form of the structural element on which it is fixed; a lateral lug for fastening it on the body of the vehicle; substantially at right angles to that of the support plate; elements; interposed between complementary portions of mutually facing surfaces of the two superimposed plate elements; assembly means; motorized reduction gear unit therein; structural element, and the housing consists of two half housings, each of which is formed in one of the two superimposed plate elements and is open in the plane of the junction of the two superimposed plate elements.
