Definitions
- the present invention relates to a plastic rear window for a motor vehicle carrying on its inner side a third brake light.
- the invention also relates to a motor vehicle equipped with such a rear window.
- Patents FR 2 766 198 and 2 779 990 describe a transparent plastic glazing that can incorporate an insert having a particular function such as a stop light.
- the rear plastic glasses have the advantage of being significantly lighter than glasses or other glass panes.
- the rear plastic sunglasses are compatible with the integration of functions such as a brake light, which is not the case of glass rear glasses.
- the light source of the brake light When the light source of the brake light is located on the inside of the rear window, the light emitted by this source must pass through the plastic material of the bezel to be visible at the rear of the vehicle.
- the plastic material of the rear window is tinted, which affects the transmission of radiation emitted by the brake light through the rear window.
- the brake light may not be visible enough to meet regulatory requirements.
- JP 2000301985 discloses a plastic rear window, covered with an outer film having a red tinted area to diffuse a red light emitted by a stop light located on the inner face of the bezel.
- EP 0745512 provides 3-th stop lamp enclosed in a housing containing a light device fixed to the rear window and which has a portion guiding the light of the luminous device to a portion of the rear window-passing aperture provided in a dark area surrounding the rear window.
- the object of the present invention is to create a plastic rear window which incorporates a third brake light satisfying the above requirements.
- This object is achieved, according to the invention, thanks to a rear window made of plastic for a motor vehicle carrying on its inner side a third brake light, characterized in that it comprises a zone in which the plastic is more transparent than in the rest of the rear window, the light source of the third stop light being positioned on the inner face of the rear window so as to diffuse the light emitted by this source through said area.
- the light source diffuses light through an area of the telescope that is more transparent than the rest of the rear window, so that the visibility of this light source is not likely to be compromised by the insufficient transparency of the rest of the window. the rear window.
- said more transparent zone is obtained by bi-injection of plastic material, forming an insert of transparent material in the rear window of less transparent plastic material.
- said zone is made of plastic whose transparency is equal to or greater than 80%.
- This transparency is sufficient to allow optimal transmission of the light emitted by the stop light.
- said plastic material is polycarbonate or polymethylmethacrylate.
- the entire rear window can be made of the same plastic with different transparencies for different parts of the bezel or different plastics compatible to form a rear window with different transparencies for different parts of the bezel.
- said more transparent zone is located in an opaque zone which surrounds the rest of the rear window.
- all the rest of the rear window is colored plastic in its mass, to effectively protect the occupants of the vehicle against solar radiation.
- said zone is made of plastic more transparent than in the rest of the rear window throughout the thickness of this area.
- said zone is made of a more transparent plastic material over part of the thickness of this zone, the remainder of the thickness of this zone consisting of less transparent plastic material identical to that constituting the rest of the telescope back.
- the light source of the stop light is made invisible when it is not lit thanks to the thickness of the tinted material and therefore less transparent, while being sufficiently visible when it is lit, thanks to the thickness of matter that is more transparent.
- This feature has an aesthetic advantage.
- the light source is constituted by light-emitting diodes or laser diodes mounted on a support provided with means for fixing the support removably on the inner face of the rear window opposite the said more transparent area.
- the invention also relates to a motor vehicle equipped with a rear window according to the invention.
- FIG. 1 is a diagrammatic view in vertical section of a first embodiment of a rear window according to the invention
- FIG. 2 is a diagrammatic plan view showing the outside face of the rear window shown in FIG. 1,
- FIG. 3 is a view similar to FIG. 1 of a second embodiment of a rear window according to the invention.
- FIG. 4 is a diagrammatic plan view showing the outside face of the rear window shown in FIG. 3,
- FIG. 5 is a view similar to FIG. 1 of a third embodiment of a rear window according to the invention.
- FIG. 6 is a diagrammatic plan view showing the outside face of the rear window shown in FIG. 5;
- FIG. 7 is a view similar to FIG. 1 of a fourth embodiment of a rear window according to the invention
- FIG. 8 is a diagrammatic plan view showing the outside face of the rear window shown in FIG. 7,
- FIG. 9 is a plan view of the transparent zone of the rear window according to the invention showing by transparency the support of the diodes constituting the light source of the stop light.
- Figures 1 and 2 show schematically a rear window 1 of plastic for a motor vehicle on its inner side 1 has a third brake light 2.
- the rear window 1 comprises a zone 3 in which the plastic is more transparent than in the rest 4 of the rear window 1.
- the light source 5 of the third brake light 2 is positioned on the inner face 1a of the rear window 1 so as to diffuse the light emitted by this source through the zone 3.
- the light diffused through the transparent zone 5 is not likely to be attenuated and to be insufficiently visible by the motorists.
- This more transparent zone 3 is obtained by bi-injection of plastic material.
- This zone 3 is made of plastic whose transparency is equal to or greater than 80%.
- the plastic material of the rear window 1 is made of polycarbonate or polymethylmethacrylate.
- the more transparent zone 3 is located at the upper part of the rear window 1 in an opaque zone 6 which surrounds the remainder 4 of the rear window 1.
- This remains 4 of the rear window 1 is made of plastic material tinted in its mass and has a transparency of less than 80%.
- the zone 3 is made of plastic more transparent than in the rest 4 of the rear window throughout the thickness of this zone 3.
- zone 3a made of a more transparent plastic material than the rest 4 of the rear window is located under opaque upper part 6, that is to say in the rest which is tinted plastic.
- the zone 3a is more transparent plastic material throughout the thickness of the rear window.
- the zone 3b or 3c is more transparent plastic on only a part of the thickness of the bezel.
- the other part of this thickness is tinted plastic as in the rest 4 of the bezel.
- This other part represents about half of the total thickness of the telescope.
- the light source 5 is less visible when the source is off, which is favorable in terms of aesthetics.
- the zone 3b of more transparent material is located in the opaque zone 6, as in the case of FIGS. 1 and 2.
- the zone 3c made of more transparent plastic material is located in the remainder 4 of the telescope, that is to say under the opaque zone 6.
- This embodiment has the advantage of masking not only the light source 5 when it is off, but also the area 3c through the part that covers it and is less transparent.
- the light source 5 may be constituted, as shown in FIG. 9, by light-emitting diodes or laser diodes mounted on a support 7 located behind the transparent zone 3, 3a, 3b or 3c.
- This support can be attached to the rear window by fastening means, such as screws or pegs or snap pins.
- optical means such as lenses may be arranged between the diodes and the transparent zone 3, 3a, 3b or 3c.
- the junction zone between the light source and the transparent material of the zone 3, 3a, 3b or 3c can be made in various configurations, such as by an optical adhesive or a transparent adhesive tape enabling the diodes of the environment to be isolated. outside and achieve adhesion with the rear window.
- the transparent area of the rear window could have a shape other than the rectangular shape shown in the figures.
- This form could be split into two or more parts.
