Glazing unit comprising a profiled clip-fastening bead having a hole
A vehicle glazing unit includes a glazed element having an outer face, an edge face and an inner face, the glazing unit including, along at least a part of a bottom edge, a profiled bead including a groove for clip-fastening a covering piece on the profiled bead, the profiled bead including, as seen in cross section, an inner leg situated beneath the inner face of the glazed element, wherein the inner leg includes, at least in a bottom part of the profiled bead, at least one hole passing through the inner leg, the hole having a length of between 2.0 and 50.0 mm and a width of between 2.0 and 10.0 mm.
1. A vehicle glazing unit comprising a glazed element having an outer face, an edge face and an inner face, said glazing unit comprising, along at least a part of a bottom edge, a profiled bead attached to said glazed element and comprising a groove for clip-fastening a covering piece on said profiled bead, said covering piece comprising, as seen in cross section, a barbed hook that passes into said groove during clip-fastening, said profiled bead being situated against said edge face of said glazed element, said profiled bead comprising, as seen in cross section, an inner leg situated beneath said inner face of said glazed element, wherein the bottom edge comprises two bottom parts disposed symmetrically on either side of a vertical axis that is centered along a length of the vehicle glazing unit, wherein the inner leg extends along said two bottom parts and comprises (a), in a region of a first of the two bottom parts a first hole void of solid material and passing through said inner leg and (b), in a region of a second of the two bottom parts, a second hole void of solid material and passing through said inner leg, and wherein the first and second holes are each centered lengthwise on a bottommost point of said profiled bead.
2. The glazing unit as claimed in claim 1 , wherein said first hole has a rectangular section with a length of between 10.0 and 20.0 mm and a width of between 2.0 and 6.0 mm.
3. The glazing unit as claimed in claim 1 , wherein said first hole is situated adjacent to a bottom part of said groove.
4. The glazing unit as claimed in claim 1 , wherein said inner leg comprises a lug which itself comprises a hole.
5. The glazing unit as claimed in claim 1 , wherein said first hole in said profiled bead, as seen in cross section, is situated between said groove and an adhesive strip which is situated on said inner leg.
6. The glazing unit as claimed in claim 1 , wherein, as seen in cross section, said outer face of said glazed element is free with respect to said groove.
7. A profiled bead for a glazing unit as claimed in claim 1 , wherein said inner leg comprises the first and second holes passing through said inner leg.
8. The glazing unit as claimed in claim 1 , wherein said first hole has a length of between 2.0 and 50.0 mm and a width of between 2.0 and 10.0 mm.
9. The glazing unit as claimed in claim 6 , wherein, as seen in cross section, an upper part of said groove is flush with said outer face.
10. The profiled bead as claimed in claim 7 , wherein said first hole has a length of between 2.0 and 50.0 mm and a width of between 2.0 and 10.0 mm.
