  "abstract": "A vehicle glazing unit including a glazed element and at least one base for reversible attachment of an accessory to the glazed element, the base including an aperture for passage of the accessory, the base including a non-flat outer face which is fastened opposite a non-flat inner face of the glazed element. The outer face includes two adhesive strips each having an elongate shape and both positioned lengthwise along the transverse horizontal axis of the glazing unit.",
  "claims": [
    "1. A vehicle glazing unit comprising: a glazed element; and at least one base for reversible attachment of an accessory to the glazed element; the base including an aperture for passage of the accessory, the base including a non-flat outer face which is fastened opposite a non-flat inner face of the glazed element; wherein the outer face includes two adhesive strips each having an elongate shape and both positioned such that a longitudinal axis of each of the adhesive strips is positioned lengthwise along a transverse horizontal axis of the glazing unit, and wherein the two adhesive strips are positioned respectively adjacent an upper and lower edge of the aperture such that a plane that extends through a center of the aperture and perpendicular to the transverse horizontal axis of the glazing unit also extends through each of the two adhesive strips.",
    "2. The glazing unit as claimed in claim 1, wherein the outer face of the base follows the same curvature as the inner face of the glazed element at a location where the base is fastened to the glazed element.",
    "3. The glazing unit as claimed in claim 1, wherein each adhesive strip is based on a mixture of epoxy resin and acrylic resin.",
    "4. The glazing unit as claimed in claim 1, wherein the outer face has no peripheral ridge around the aperture.",
    "5. The glazing unit as claimed in claim 1, wherein the adhesive strips have the same dimensions in terms of length, height, and thickness.",
    "6. The glazing unit as claimed in claim 1, wherein the adhesive strips are positioned substantially parallel to each other.",
    "7. The glazing unit as claimed in claim 1, wherein at least one adhesive strip includes an angled part at each of its two longitudinal ends along the transverse horizontal axis.",
    "8. The glazing unit as claimed in claim 7, wherein each of the two adhesive strips includes an angled part at each of its two longitudinal ends along the transverse horizontal axis, and the two adhesive strips are positioned head to tail.",
    "9. The glazing unit as claimed in claim 1, wherein the total surface area of the two adhesive strips represents approximately one half of the surface area of the outer face.",
    "10. The glazing unit as claimed in claim 1, wherein the glazed element is a laminated glazed element.",
    "11. A method for manufacturing the glazing unit as claimed in claim 1 including the glazed element and the at least one base for fastening the accessory, the method comprising: bonding the base to the inner face of the glazed element by the two adhesive strips located on the outer face of the base, each of the adhesive strips having an elongate shape and both strips being positioned lengthwise along the transverse horizontal axis of the glazing unit.",
    "12. The method for manufacturing a glazing unit as claimed in claim 11, wherein the glazed element is a laminated glazed element and the bonding of the base is carried out during a laminating operation.",
    "13. Use of a base for reversibly fastening the accessory to a glazed element as claimed in claim 1, the base being bonded to the inner face of the glazed element by the two adhesive strips located on the outer face of the base, each of adhesive strips having an elongate shape and both strips being positioned lengthwise along the transverse horizontal axis of the glazing unit.",
    "14. A base for fastening an accessory to a vehicle glazing unit, the base comprising: two adhesive strips, each having an elongate shape, wherein the vehicle glazing unit includes a glazed element and the base for reversible attachment of the accessory to the glazed element, wherein the base includes an aperture for passage of the accessory, the base including a non-flat outer face which is fastened opposite a non-flat inner face of the glazed element, wherein the outer face includes the two adhesive strips, and both of the adhesive strips are positioned such that a longitudinal axis of each of the adhesive strips is positioned lengthwise along a transverse horizontal axis of the glazing unit, wherein the two adhesive strips are positioned respectively adjacent an upper and lower edge of the aperture such that a plane that extends through a center of the aperture and perpendicular to the transverse horizontal axis of the glazing unit also extends through each of the two adhesive strips."

  "description_excerpt": "The present invention relates to the fastening of an accessory or accessories to glazing units of vehicles, and more particularly to glazing units of motor vehicles.\n\nA base is usually fastened against the inner face of a glazed element of a vehicle glazing unit, in order to enable one or more accessories to be attached mechanically to the base in the immediate proximity of this inner face.\n\nThe accessory may be, for example, a rain and/or light sensor, or a detector or a camera.\n\nThe precise positioning and fastening of the base against the inner face of the glazed element then enables the accessory to be precisely positioned and mounted against, or practically against, this inner face.\n\nA base 3 ′ according to the prior art is shown face-on in FIG. 1; a glazing unit 1 ′ including a glazed element 2 and this base 3 ′ for the reversible attachment (mechanical mounting) of an accessory to said glazed element 2 is shown in FIG. 2, which is a sectional view taken along AA′ in FIG. 1.\n\nThe base 3 ′ has an aperture 30 for the passage of said accessory, to enable a surface of said accessory to be placed opposite the inner face 22 of said glazed element.\n\nThe base 3 ′ has a non-flat (or “curved”) outer face 31 ′, with a non-infinite radius of curvature in two perpendicular directions, which is fastened, by chemical fastening, opposite a non-flat (or “curved”) inner face 22 of said glazed element 2, which also has a non-infinite radius of curvature in two perpendicular directions. The outer face 31 ′ is located on the periphery of the aperture 30, and completely surrounds the aperture.",
