Definitions

  • the present invention relates to a laminated glass windscreen having a predetermined taper angle and intended to be used at the same time as a reflector in a HUD system.
  • thermoplastic intermediate sheet with a tinted filtering band during the manufacture of curved windscreens made of laminated glass with a filtering strip along the upper edge.
  • the desired curvature of the filtering strip is then obtained by intentional irregular stretching of the sheet.
  • This stretching involving plastic deformation of the sheet, is carried out in order to adapt the profile of the filtering strip to that of the upper part of the laminated windscreen.
  • Stretching in the shape of a circular arc leads to a taper on the long side of the curvature, which gives a sheet with a wedge-shaped cross-section.
  • the taper angle of a sheet stretched in this way is determined by the radius required for the filtering strip.
  • thermoplastic sheet with wedge-shaped cross-section formed in this way does not normally have the taper angle needed for a windscreen to be used as a reflector in a head-up display (HUD) system comprising two reflection surfaces which form a determined angle in order to superimpose the images.
  • HUD head-up display
  • An object of the invention is to provide a laminated glass window which contains a tinted filtering strip integrated with the thermoplastic intermediate sheet, whose curvature is adapted to that of the upper edge of the laminated glass pane and whose two panes also form, relative to one another, an angle such that they serve as a reflector in a head-up display system, resulting in two reflected images which are superimposed with a view to enhancing brightness and avoiding a double image.
  • an intermediate layer comprising at least two thermoplastic sheets, one of which is provided along its upper edge with a tinted filtering strip, and the other has a wedge-shaped cross-section such that the two sheets together have the desired taper angle.
  • FIG. 1 is a front view of a windscreen with a tinted filtering strip
  • FIG. 2 is a view in section on the axis II-II in FIG. 1.
  • FIG. 3 is a view in section on the axis II-II in FIG. 1, of an embodiment different from that of FIG. 2.
  • a laminated glass window according to the invention has the advantage that the two reflecting surfaces can be arranged relative to one another with a predetermined taper angle, with a view to using the windscreen as a reflector in a HUD system, irrespective of the taper angle already presented by the thermoplastic sheet with the incorporated tinted filtering strip.
  • the laminated glass windscreen prefferably has a straight edge at the filtering strip.
  • the sheet comprising the filtering strip does not need to be stretched, and consequently no longer has a wedge-shaped cross-section. The required taper angle is then produced only by the other sheet.
  • a support sheet comprising a functional layer is placed between the thermoplastic sheets which together form the defined taper angle.
  • This support sheet may, for example, be made of polyethylene terephthalate (PET) and be provided with a coating which reflects infrared wavelengths, but is transparent to other wavelengths.
  • thermoplastic sheets may be obtained by stretching with plastic deformation, but it is also possible to use sheets originally extruded with a wedge-shaped cross-section.
  • the sheet provided with the tinted filtering strip may itself also be extruded with a wedge-shaped cross-section.
  • thermoplastic sheets which together are to form the determined taper angle.
  • polyvinyl butyral and polyurethane sheets are suitable.
  • the windscreen 1 is provided along its upper edge with a tinted filtering strip 2 .
  • this windscreen may be produced with a taper angle ⁇ in order to ensure superimposed reflection of an image by the exterior surfaces 31 and 61 of the panes 3 and 6 .
  • the taper angle ⁇ is selected to be 0.5 mrad.
  • the laminated glass windscreen 1 has a radius R 1 of 3.30 m, and its height h is 0.80 m.
  • d 1 is the initial thickness of the sheet
  • R 1 is the radius of curvature at the upper edge
  • the sheets are then assembled in the conventional way with the curved panes 3 and 6 to form a laminated glass windscreen which exhibits the required taper angle of 0.5 mrad.
  • R 1 , h, and d 1 are easily selected by those of ordinary skill in the art, and in part depend on dimensions of the specific vehicle in which the windscreen is intended to be used.
  • R 1 may be 2-4 m
  • h may be 0.40-1.6 m
  • d 1 may be 0.10-2.50 mm.
  • d 2 may be 0.10-2.50 mm.
  • a third sheet may be included, such as a support sheet comprising a functional layer between the thermoplastic sheets. Such an embodiment is illustrated in FIG. 3, where the support sheet 7 , is between the thermoplastic sheets 4 and 5 .
