Definitions

  • the invention is directed to a visor, in particular for motorcycle helmets, comprising at least one transparent viewing window.
  • Such visors on motorcycle helmets, ski helmets or safety helmets must on the one hand protect the eyes of the user effectively against wind and particles, but on the other hand allow the user as unrestricted and unobstructed view.
  • the object of the invention is to design such a visor in such a way that, in particular, glare is avoided.
  • This object is achieved in that the lens is connected to a polarizing film.
  • the polarization effect must be such that the transmission is for unrestricted use of the visor at 80 to 100%, for a daytime use at 50 to 80%. It is preferably provided that the polarization film is formed as a plate-shaped material or connected to a plate-like carrier material.
  • the viewing window may also consist of a plate-like material and be defined together with the polarizing film curved in a frame, d. H. the curvature is given and determined by the frame.
  • the polarizing film is disposed between an outer and an inner plate-like material.
  • the inner and outer discs may be acetate.
  • the outer disc made of polycarbonate and the inner disc made of acetate can also be provided that the outer disc made of polycarbonate and the inner disc made of acetate.
  • the acetate discs consist in particular of cellulose acetate, preferably cellulose triacetate.
  • the polarizing film is arranged between two acetate disks, which are in turn connected to a polycarbonate disk with the interposition of an air cushion.
  • the acetate discs are provided on their respective outside with an anti-fog coating.
  • a circumferential silicone bead is arranged to form an insulating air cushion.
  • a further embodiment provides that the viewing window is made of polycarbonate and is provided on its outer side with a polarizing film, which is preferably laminated.
  • a lens 2 is fixed to a frame 1, which comprises an outer polycarbonate disc 3 and an inner cellulose acetate disc 4, between which there is an air cushion 5, which is ensured by a circulating on the edge silicone bead 6.
  • the acetate disc 4 is provided on both sides with an anti-fog coating.
  • the outside of the polycarbonate pane 3 is laminated with a polarizing film 7. This outer polycarbonate pane 3 is coated on both sides scratch resistant.
  • a viewing window 2 is attached to a frame 1, which again comprises an outer polycarbonate pane 3, a circumferential silicone bead 6 and at a distance from the outer polycarbonate pane 3, including an air cushion 5 Disc combination 8.
  • the structure of the disc combination 8 is shown in Fig. 3.
  • the inner disk comprises an outer cellulose acetate disk 9, an inner cellulose acetate disk (alternatively, a polycarbonate disk may also be provided) 10 and a polarizing film 7.
