- Such a profile is generally attached to the inner face of the glazed element (or inner face of the inner glass sheet) with the aid of an inner wing which is glued against this inner face.
- this inner wing For good adhesion of this inner wing to the glazed element, this inner wing must be relatively wide (when the profile is observed in cross section).
- the cover piece In the first situation, the cover piece must be sufficiently wide, to cover at least the inner wing so that it is not visible from the outside and / or a masking tape is made outside more than the outside. inner wing.
- a masking tape is made more outward than the inner wing to cover at least the inner wing so that it is not visible from the outside.
- cover piece and / or the masking tape are, themselves or together, at least as wide as the inner wing and generally wider than the inner wing; as a result, the clear view through the glazed element is diminished.
- the bead of glue that adheres the glazing to the adjacent bodywork must be positioned more towards the center glazing; however, this bead of glue must also be masked from the outside.
- One of the objectives of the present invention is to provide a glazing solution overcoming the drawbacks of the prior art, incorporating a profile for the management of water which is firmly attached to the glazed element, and to increase the light view through the glazed element.
- glazing in particular a vehicle glazing, comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet, and at least one plastic interlayer sheet located between said glass sheets,

- the cover piece 8 is here intended to be positioned more outwardly than the profile 6 and to cover at least in part when the glazing 1 is viewed from the outside E.
- This is, in the context of the application to a lower edge of a windshield, an awning grid for making a junction visual between the windshield and the engine hood, while channeling the runoff and ensuring at the same time a ventilation of the engine compartment through ventilation openings (not shown).
- An awning grid is typically made of a plastic material.
- the cover piece could also be a hubcap intended to limit the penetration of water on the side of the glazing through the presence of a lip located against the rabbet 9.
- the outer face 8a of the awning grid substantially flat, is intended for the evacuation of runoff, including rainwater dripping on the windshield, and an inner face 8b opposite is provided a harpoon 80 for penetrating into the groove 61 of the profile 6 during clipping.
- the groove 61 has a mouth and a bottom: when clipping the cover piece 8, the harpoon 80 enters the groove 61 through the mouth and towards the bottom; generally, in the clipped position, the harpoon 80 does not touch the bottom of the groove.
- the mouth of the groove, through which the harpoon 80 is introduced, is made by two gutters: a distal gully 67, situated to the left of the harpoon 80 in FIG. 1 and a proximal gully 68, situated to the right of the harpoon 80 on this same figure. These two drains are intended to guide the harpoon 80 accurately to the bottom of the groove 60 during clipping.
- the two drains 67, 68 of the mouth of the groove 61 are each in the form of a hammer with the heads almost opposite one another.
- Spear 80 is double: it is constituted, seen in cross section, two bosses facing away from one another.
- the clipping thus consists in the penetration of the harpoon 80 inside the groove 61 and more precisely the two bosses of the harpoon inside the groove 61 and under the two drains.
- the width of the mouth is less than the width of the two bosses at the widest.
- the groove 61 does not protrude from an artificial plane situated in the continuity of the outer surface 3a of the outer glass sheet 3: the profile is flush with the outer surface 3a of the outer glass sheet 3.
- the distal outer edge of the functional portion 60 (on the groove 61 side furthest from the glazing element 2 in FIG. 1) is located less outward than the proximal outer edge of said portion 60 (on the the groove 61 closest to the glazed element 2 in Figure 1) so that when the cover piece 8 is clipped into the groove 61 an outer face 8a of the cover piece 8 can be in continuity with the outer surface 3a of the outer glass sheet 3; it is said that the cover piece is "flush” with the outer glass sheet 3.
- the profile 6 does not protrude further outside than the outer face 3a of the outer glass sheet 3.
- cover piece 8 is present above the groove 61 but does not protrude above the outer face 3a.
- the bottom of the groove 61 may itself be located more inside than the inner face 5b; this does not interfere with the positioning of the glazing in the bay of the bodywork because there is room between the inner face 5b and the rebate 9 for the adhesive bead C.
- the profile 6 is thus laminated between the two glass sheets 3, 5 of the glazed element and fixed to these sheets 3, 5 by means of plastic sheets 41, 42, also known as “interleavers”. "Laminating”. These plastic sheets 41, 42 here ensure both the attachment of the glass sheets 3, 5 to each other, and the attachment of the profile 6 to the glazed element 2.
- the profile 6 is, at least partly, integrated in the glazed element 2 at the time of lamination.
- Figure 11 illustrates different manufacturing steps of the glazing 1 of Figure 1, according to a possible implementation mode.
- a first step (A) the inner spacer sheet 42 is deposited on the intermediate face 5a of the inner glass sheet 5.
- a second step (B) the profile 6 is arranged so that the intermediate wing 71 is superimposed with said inner spacer sheet 42.
- the inner glass sheet 5, the inner spacer sheet 42 and the intermediate wing 71 form a first stack.
- a third step (C) the upper intermediate sheet 41 is disposed on the first stack.
- a fourth step (D) the outer glass sheet 3 is disposed on the upper intermediate sheet 41.
- the intermediate wing 71 is thus disposed between the outer glass sheet 3 and the inner glass sheet 5 and fixed to said glass sheets 3, 5 by means of the interlayer plastic sheets 41, 42.
- the profile 6 is formed with its body portion of thermoplastic material 65 before the lamination step.
- the body portion 65 may also be formed around the distal portion of the fixing insert 64 projecting out of the glazed element 2, after lamination.
- the steps A to D may be identical to those described above but successively by a step E of coating the distal portion of the fixing insert 64 protruding from the glazed element 2 as illustrated in FIG. 12.
- the coating step E is, for example, a step of overmoulding at least one portion of the distal portion of the insert 64 by the body portion made of thermoplastic material 65.
- implementation has the advantage of allowing, for the body portion 65, the use of materials incompatible with the lamination step, for example materials not resistant to high temperatures or pressures.
- a plastic interlayer sheet In the example of Figure 11 for example, one could pre-assemble the plastic interlayer sheet 41 and the outer glass sheet 3 before disposing the assembly pre-assembled on the first stack.
- FIG. 2 illustrates a variant of profile 6 that can be used in a glazing unit according to the invention, in which the intermediate wing 71 formed by the proximal part of the fixing insert 64 has a plurality of through openings 75, here distributed regularly on its surface. These openings open at the same time on the outer face 71a and on the inner face 71b of the intermediate wing 71.
- the spacer wing 71 may comprise one or more non-through cavities, opening on only one of its outer face 71a and its inner face 71b.
