- the support mount 10 is provided to provide rigidity to the wiper blade, said mount 10 is further advantageously flexible. Indeed, it is also intended to adapt the broom plating according to the windshield to be wiped.
- the upper housing 30 has a plurality of recesses 32 facilitating the bending of the frame 10, the recesses 32 forming a pattern M1 -M10 to the surface 33 of the upper housing 30, said pattern of distribution of the recesses M1 - M10.
- the recesses draw a pattern M1 -M10 on the upper housing 30, this pattern M1 -M10 being particularly visible for an observer who looks, in top view, a support frame 10 made according to the invention.
- the recesses 32 are visible to the naked eye for an external user and their regular or irregular repetition forms a geometrical signature of the support frame 10.
- geometric signature is meant a set of geometric shapes , straight lines and / or curves, which, taken together, form the visual identity of the support frame 10. This geometric signature is particular visible on the surface 33 of the upper housing 30.
- Said pattern M1 -M10 is advantageously defined by the distribution of the recesses 32 along the main direction X and / or by the orientation of the recesses 32, 32 ', 32 "relative to the main direction X.
- the lower housing 20 is located opposite to the upper housing 30, and in relation to the base 31 of the upper housing 30. It is particularly visible in FIGS. 1 and 2, an exemplary embodiment of two recesses 32, 32 'made in the form of slots of width L1, length L3 and which are spaced from each other by a distance L2.
- L1 represents the cutting width of a recess 32, 32 '; it can vary from a few tenths to a few millimeters.
- L2 represents the step, ranging from 5 to 50mm.
- the pitch between the recesses 32 distributed along the main direction X may be variable and not regular.
- This pitch L2 may be 5mm at the center 41 of the frame and go 50mm to the end 42 of the frame (see Figure 6).
- the first zone may comprise recesses 32 very close together, or whose pitch between them is very small, as illustrated in FIG. 14 (example which will be described in detail later).
- the second zone corresponding to the center 41 of the frame, may have little or no understanding of recesses 32.
- the third zone meanwhile, may include recesses 32 whose steps that separate them are variable.
- a pattern M1 -M10 to another. L3 is the cutting length; it represents a percentage of the width
- the value L3 varies from 5 to 100% of the width L of the surface 33 of the upper housing 30.
- the recesses 32, or cuts may take different forms, as well as orientations, positions and not variable.
- the pattern M1 for distributing the recesses 32 comprises a plurality of recesses 32 oriented substantially perpendicular to the main direction and regularly spaced from each other.
- the pattern M2 for distributing the recesses 32 comprises a plurality of recesses 32 oriented substantially perpendicular to the main direction and regularly spaced from one another. On the other hand, these are staggered along the main direction X, in particular in order to obtain more flexibility of the support frame 10 without reducing its blade retention function.
- the pattern M3 comprises recesses 32 with a pitch separating two consecutive recesses 32 which is variable. This variable step makes it possible to adapt the distribution of the desired stresses on a vehicle windshield to be wiped.
- the example illustrated in FIG. 7 comprises recesses 32 oriented with respect to the main direction X in at least one direction secant to the main direction X, here in two directions A, B which intersect at the main direction X.
- the pattern M4 thus formed is similar to offset chevrons.
- the pattern M5 is similar to chevrons forming an arrow head, in particular by pairs of recesses 32, 32 'which join to the level of the main direction X.
- the pitch between two rafters of patterns M4 and M5 can be fixed but also variable. It is also interesting to note that the rafters can be all oriented in the same direction to facilitate the sliding of the vertebra inside the upper housing 30 in the assembly phase.
- the distribution pattern M6 of the recesses 32 comprises a plurality of recesses 32 drawing a curve C, the curve C extending substantially transversely to the main direction X.
- the distribution pattern M7 of the recesses 32, 32 "further comprises a plurality of recesses 32" oriented substantially parallel to the main direction X, so as to draw shapes in " T "when these recesses 32" are combined with recesses 32 which extend substantially perpendicular to the main direction X. It is also interesting to note that the shapes in "T” can be oriented all in the same direction to facilitate sliding of the vertebra inside the upper housing 30 in the assembly phase. The flexibility of the frame 10 with this M7 distribution pattern is then optimized.
- the distribution pattern M8 comprises recesses 32 oriented with respect to the main direction X in two directions A, B which are intersecting at the main direction X, so as to draw shapes in "X" when these recesses 32 are combined with each other. It is interesting to note that a small pitch between the shapes "X" will further optimize the flexibility given to the frame 10 by this example of pattern M8.
- the longitudinal flexibility is controlled progressively so as to increase the rapid curving of the support frame 10 when mounted on a vehicle in static to avoid the latency effect due to the rigidity of the plastics used, or even to balance rigidity due to cold / winter temperature conditions.
- the support mount 10 will preferably be made of plastic material; although any other material is possible, for example a metallic material.
- the recesses 32 can be easily provided during the manufacture of said frame 10 of a plastic material polypropylene type (PP).
- the lower housing 20 may also include recesses 23 (see FIGS. 12 and 13a, 13b and 13c).
- the support mount 10 is recessed at the lower housing 20 with recesses 23 and at the upper housing 30 with recesses 32 so as to form the pattern marked M9 in FIG. 12.
- the support frame 10 is held by a material bridge 34 visible on the side views ( Figure 13a), from above ( Figure 13b) and from below ( Figure 13c). This material bridge 34 serves as a binder between the parts devoid of recesses 32, 23.
- the material bridge 34 and a continuous longitudinal portion of the base 31 makes it possible to obtain maximum flexibility while preserving a guiding and sufficient retention of the vertebra and heel of the wiper blade.
- the pattern M9 makes it possible to obtain a frame 10 that is as transparent as possible in the operation of the blade 50 that will be provided with it, in terms of taking static and dynamic curves.
- the example illustrated in Figure 14 is a combination of patterns as described above.
- the pattern M10 has herringbone recesses with a variable pitch, along the main direction X, between each of them.
- the stresses, or stresses E1-E7, applied by the frame 10 of the invention to the windshield of a vehicle with which it is intended to cooperate are different along the main direction X.
- these stresses E1 - E7 are higher as the pitch decreases from the center 41 of the mount 10 to the tip 42 thereof.
- the chosen pattern M1 -M10 induces a mechanical behavior in deformation according to the different sections of the support frame 10 along the main direction X.
- sections means the zones of the frame 10 which are between two recesses. 32 consecutive along the main direction X.
- the recesses 32, 32 ', 32 ", 23 will preferably pass through the upper housing 30, or even the lower housing 20, in their thickness, thereby forming lumens through the material of these housings 20, 30.
- the upper housing 30, in particular above said vertebra to be able to receive a heating element (embodiment not shown).
- the heating element extends along the main direction X.
