    "Wiper blade"
    Field of the invention
    The present invention relates to a wiper blade having a wiper blade provided with at least one elongated support member and a deflector connected to the wiper blade, the wiper blade being hingedly connected to a wiper arm, with between the wiper blade and the deflector, at least one passage opening in the longitudinal direction of the wiper blade, in the area of the wiper arm.
    State of the art
    According to the document DE 103 12 979 A1, there is known a windscreen wiper blade including motor vehicle windows. It has an elongated, elastic rubber wiper blade with a wiper lip applied against the vehicle window; an elongate, ribbon-shaped elastic rail is a support member which distributes along the longitudinal extension of the wiper blade the application force exerted by the wiper arm. The elastic rail is housed in a central longitudinal channel of the head bar of the wiper blade. A deflector is attached to the head bar by means of bearings engaged by retaining claws in the longitudinal grooves of the head bar. The height of the supports is sized to form a flow channel between the baffle and the wiper blade. The deflector is divided transversely to its longitudinal direction and each of the parts is in the extension of a connecting element for connecting the wiper arm in an articulated manner. This has for this purpose a connecting element at its end. The adjacent supports of the deflector form the lateral limit of the passage orifices. The deflector has a section similar to that of a load-bearing wing so that a narrow passage is formed near the front side of the wiper blade and from there the section of each passage opening enlarges. in the direction of flow. The wiper arm is located above the wiper blade and baffle; by its connecting element, it is connected to the connecting element of the wiper blade according to the so-called toplock principle.
    During the wiping operation, due to aerodynamics during the downward movement of the wiper blade, water is pushed from the front upright A of the vehicle to the rear edge of the window. This phenomenon hinders visibility and many drivers perceive it as disruptive.
    Advantages of the invention For this purpose, the invention relates to a windscreen wiper blade of the type defined above, characterized in that the windscreen wiper arm covers at least partly the passage opening of the windscreen wiper blade. zone facing the deflector, the downstream side, in the mounted position and deflects the flow of air passing through the passage opening to the vehicle window.
    The through holes between the wiper blade and the baffle reduce the recirculation area of the passing wind behind the wiper blade and thus the return of the water. The design according to the invention further improves the influence at the connection element in that by experience the greatest amount of water accumulates at the wiper.
    In principle, the wiper arm can be installed on the leading side or on the downstream side of the wiper blade. In the case of the current wiper blades, which in the storage position are placed under the lower edge of the windshield in the gap between the hood and the bonnet, the arm is generally provided on the side lower that is to say the leading side of the wiper blade. For such a configuration, it is advantageous according to a development of the invention that the drive end of the wiper arm is in front of the wiper blade in the direction of the flow while the part adjacent to the connecting element is behind the soot-ice broom in the direction of flow and the two parts are connected by a cross-piece straddling the wiper blade.
    Advantageously, the cross member passes through a clearance of the baffle in the mounted position.
    In order for the part of the wiper arm on the downstream side, to deflect the air stream passing through the passage opening, efficiently towards the windscreen, the wiper arm has at its end on the drive side a rectangular section profile whose wide sides are aligned on the attack side mainly in the deflector while on the downstream side, they are practically directed transversely to the direction of flow.
    Thus, it does not matter whether the part of the wiper arm partly covers the passage opening is formed by the wiper arm itself or by a connecting element secured thereto. drawings
    The present invention will be described below in more detail with the aid of an exemplary embodiment shown schematically in the accompanying drawings in which: - Figure 1 is a perspective view of a wiper blade seen 2 is a perspective view of a wiper blade seen from the downstream side; FIG. 3 is a section along the line III-III of FIG. 1, and FIG. FIG. 4 is a section along line IV-IV of FIG. 1. DESCRIPTION OF AN EMBODIMENT
    A wiper blade 10 comprises an arm 12 with a hinge part 14 and a wiper rod 16. The hinge part 14 is hingedly connected to a fastener not shown and driven in pivoting by a drive shaft also not shown. The end of the wiper rod 16 integrally carries a connecting element 20. The latter is hingedly connected to a connecting element 21 fixed to the wiper blade 22, the connection being made according to the principle Toplock (top lock) or Sidelock (side lock).
    The wiper blade 22 has a wiper blade 24 formed by a rubber profile 26 whose lip 28 is applied against the window 50 of the vehicle in the operating position. The profile 26 comprises an elastic rail 30 integrated in a central longitudinal channel; this elastic rail serves as a support element for the wiper blade 22 in place of an elastic rail 30, it could also provide two elastic rails housed in lateral grooves of the rubber profile 26.
    The wiper blade 24 is connected by supports 40 to a deflector 32 having a profile in bearing surface section 34. Between the deflector 32 and the supports 40 and the upper surface of the wiper blade 24, the through openings 38 through which the flow of the flow passes in the direction of flow 36.
    The deflector 32 is made in two parts. The two parts extend in the longitudinal direction of both sides of a connecting member 21 integral with the wiper blade 24. The wiper blade 12 passes with its drive end end, the hinge part 14 and a portion of the wiper rod 16, adjacent, on the drive side of the wiper blade 22; its surface is aligned according to the deflector 32 and thus enhances the effect of the deflector. A portion 18 of the wiper rod 16 having a substantially rectangular section and connected to or forming part of the connecting member 20, the shank 16 at the deflector 32 covers a portion of the through hole 38 and thus deflects the corresponding portion of the air stream 46 passing through the through orifice 38 to the windshield 50. This results in a very low return flow 48 whereas in the immediate vicinity of the windshield, it develops an air flow 46 which opposes the return of water (Figure 3).
    The part 18 of the wiper rod 16 located on the downstream side, is connected to the upstream side part by a cross member 44 passing through a clearance 42 of the upper side of the deflector 32.
    The present invention applies under the same conditions to windscreen wipers whose wiper arm 12 is located along its entire length on the downstream side of the windscreen wiper blade 22. It is important that the arm cover a part of the passage orifices 38, in particular the passage orifices 38 adjacent to the connecting element 21 and deflect the air stream towards the window or windshield 50. In addition, the invention can also be applied to wiper blades 22 having passage holes 38 only in the drive-side region near the connecting element 21, while in the other parts of the wiper blade 22 the gap between the deflector 32 and the wiper blade 24 is closed.
    To explain the effect of the configuration thus described, FIGS. 3 and 4 show the lines of circulation of the air stream 46 for the sections III-III and IV-IV of FIG.
