Definitions
- the present invention relates to a plastic rear window for a motor vehicle carrying a third brake light.
- the rear glasses are usually glass and have the disadvantage of having a high mass.
- Some vehicles such as soft-top convertibles, have a plastic rear window such as PVC.
- Patents FR 2 766 198 and 2 779 990 disclose rear spectacles which do not have the above disadvantages.
- Certain elements having particular functions can be added to these rear windows.
- the object of the present invention is to provide improvements to the rear glasses above.
- a plastic rear window for a motor vehicle carrying a third brake light characterized in that it comprises a zone in which the plastic is more transparent than the plastic material constituting the rest of the rear window, the light source of the third stop light being disposed facing a peripheral portion of the rear window on which a first portion of said zone opens, a second portion of this zone opening into the plastic material constituting the remainder of the telescope, so that the light emitted by the light source can pass through said zone.
- the area of plastic more transparent than that of the rest of the bezel thus plays the role of a light guide that guides the light emitted by the light source.
- This zone in a more transparent material makes it possible to reduce the absorption of light intensity that the light undergoes while passing through the plastic material which constitutes the remainder of the bezel which is less transparent because it is tinted to protect the occupants with regard to the radiation. solar.
- the arrangement of the light source facing a slice of the telescope makes it easy to make this source invisible when it is not lit.
- This arrangement improves the aesthetics of the rear window.
- said zone where the plastic is more transparent than that of the rest of the rear window is obtained by bi-injection of plastic material forming a transparent material insert in the rear window of less transparent plastic material.
- said second part of the zone where the plastic is more transparent opens onto a surface of the rear window which is substantially perpendicular to said wafer.
- This third inclined portion deflects the light emitted by the light source to make it appear on the outer face of the bezel.
- the angle of inclination will be chosen judiciously according to the desired output on the outer face of the telescope.
- This arrangement also makes the stop light invisible when the light source is off.
- the second portion of said more transparent zone preferably opens onto the outer surface of the plastic material which is less transparent and which constitutes the remainder of the plastic material.
- the second portion of said zone opens onto a screen-printed part.
- an opaque zone is generally provided on the periphery of the telescope. It can therefore be obtained by a silkscreened part. It can be formed by a zone of plastic material opaque, also bi-injected, compatible with the plastic used for the rest of the telescope.
- the second part of said zone of transparent material is entirely confined within the less transparent plastic material constituting the remainder of the rear window.
- the second portion of said transparent material zone is entirely confined in an opaque zone, for example screen-printed on the telescope.
- the zone of more transparent plastic material has a transparency equal to 80%.
- the tinted plastic which constitutes the rest of the telescope has a transparency of less than 80%.
- the plastic material of the telescope is for example polycarbonate or polymethylmethacrylate or any other suitable material.
- the entire rear window may be made of the same plastic material which has different transparencies, and in fact different refractive indices, the most transparent part having a refractive index allowing it to act as a light guide .
- the most transparent zone is made of a plastics material that has a refractive index that is appropriate to that of the plastics material of the remainder of the bezel, that is to say greater, the materials being compatible.
- the invention also relates to a motor vehicle equipped with a rear window according to the invention.
- FIG. 1 is a plan view of the outer face of a first embodiment of a rear window according to the invention showing the stop light on,
- FIG. 2 is a view similar to FIG. 1 showing the stop light extinguished
- FIG. 3 is a sectional view along the plane III-III of FIG. 1
- FIGS. 4, 5 and 6 are views similar to FIGS. 1, 2 and 3, respectively, relating to a second embodiment of the invention
- FIGS. 7, 8 and 9 are views similar to FIGS. 1, 2 and 3, respectively, relating to a third embodiment according to the invention;
- FIGS. 10, 11, 12 are views similar respectively to FIGS.
- Figures 1, 4, 7 and 10 and 2, 5, 8 and 1 1 each represent a rear window 1 according to the invention made of plastic, such as polycarbonate or polymethyl methacrylate.
- the rear window 1 has an opaque peripheral zone 2 and the plastic material 3 which constitutes the major part of the telescope is tinted in the mass to protect the occupants of the vehicle with respect to solar radiation.
- each of the rear windows 1 is integrated a stop lamp 4 whose light source 5 is constituted by light-emitting diodes or laser encapsulated in a shell 6 of plastic (see in particular Figures 3, 6, 9 and 12) related to the rest of the bezel 1.
- the diodes 5 of the light source of the brake light 4 are arranged in a row on the upper peripheral edge 2a of the bezel 1.
- the rear window 1 comprises a zone 7, 7a,
- This zone 7, 7a, 7b, 7c (see in particular Figures 3, 6, 9 and 12) in which the plastic is more transparent than the plastic material 3 constituting the remainder of the rear window 1.
- This zone 7, 7a, 7b, 7c consists of a material whose refractive index is appropriate relative to the material constituting the remainder of the bezel to enable it to act as a light guide.
- This zone 7, 7a, 7b, 7c comprises a first portion 8, 8a, 8b, 8c which opens on the upper peripheral edge 2a of the bezel 1 and a second portion 9, 9a, 9b, 9c opening into the plastics material 3 constituting the remainder of the telescope, so that the light emitted by the light source can cross the zone 7, 7a, 7b, 7c as shown by the arrows F, Fi, F 2 , F 3 .
- the zone 7, 7a, 7b, 7c where the plastic is more transparent than that of the rest 3 of the rear window 1 is obtained by bi-injection of plastic material.
- the second part 9, 9a of the zone where the plastics material is more transparent opens onto the outer surface 2b of the rear window which is substantially perpendicular to the wafer 2 where the diodes are arranged. 5.
- the angle of inclination of this third part is appropriately chosen to ensure the output of the 3 rd brake light towards the outside of the vehicle and good visibility of the fire stop regardless of the inclination of the bezel on the vehicle.
- the second portion 9, 9a of the zone 7, 7a opens on the outer surface 2b of the plastics material 3 which is less transparent and which constitutes the rest of the plastic material.
- the second portion 9a of the zone 7a opens onto a part made of screen-printed material forming the opaque zone.
- the second portion 9b of the transparent material zone 7b is entirely confined within the less transparent plastics material constituting the remainder of the rear window.
- This second part 9b is separated from the outer surface 2b of the bezel by a relatively thin layer of plastics material 3 which, as indicated above, is less transparent than that of the area 7c.
- the second portion 9c of the zone 7c made of transparent material is almost entirely confined in an opaque zone, for example screen-printed on the telescope.
- the zone 7, 7a, 7b, 7c of more transparent plastic material has a transparency equal to or greater than 80%.
- the material 3 which constitutes the rest of the plastic material of the bezel has a transparency well below 80%.
