Definitions
- the subject of the invention is a bodywork element of a motor vehicle and more particularly a piece of style intended to contribute to the general exterior appearance of the vehicle.
- These style parts or bodywork elements are intended to enhance a line or emphasize a shape in order to reinforce the image that the manufacturer wants to associate with its make or model of vehicle.
- the chrome strips running along the side of the vehicle, the sill protectors, the logo of the brand, the door handles hubcaps, the hulls of mirrors are these pieces of style whose design is the subject of special care on the part of the designers of the vehicle.
- all parts of the body visible from the outside and participating in the general appearance of the vehicle, such as an opening, a bumper, a grille, can also be considered as bodywork elements or style parts within the scope of the invention.
- the optical device when the vehicle is illuminated by daylight, the optical device is off, and the appearance of the bodywork element is given by the paint coating forming the outer layer of the bodywork element.
- the bodywork element appears as a uniformly bright surface.
- US Pat. No. 5,249,104 describes a light device comprising light sources disposed in cavities formed in a diffusing body whose bottom is equipped with a reflective surface, an upper plate formed of a material dispersing light surmounted by a semi-reflecting mirror, and a body transparent whose outer portion is covered with a non-uniform opaque coating revealing a pattern when the light device is activated.
- the semi-reflecting mirror obscures the inner part of the device when the room is exposed to daylight.
- the publication FR 2 840 269 describes a piece of style, supporting a logo or a monogram, composed of a transparent material, behind which are arranged one or more light sources, and whose outer surface comprises a semi-reflective coating that allows light to pass only in one direction.
- these light bodywork elements have the disadvantage of having light sources arranged directly in the rear part of the surface forming the skin of the bodywork element. The light sources are then exposed to shocks and external climatic conditions experienced by the bodywork element itself. It is then necessary to provide an encapsulation adapted to ensure the protection of the light source, and a particular optical device for distributing the light uniformly to the outer surface of the body member.
- optical fibers to route the light from a remote source.
- the optical fibers have the advantage of having a certain flexibility to circulate the fibers along predetermined paths in a much safer way and over a greater path than a light guide molded in a rigid and brittle material.
- the invention aims to eliminate the disadvantages mentioned above.
- the bodywork element comprises a support integrated in the vehicle body, and a plurality of optical fibers of given length, a first end of which rests on the side of the support facing the outside of the vehicle, the portion of the optical fibers resting on the support being diffusing so that the light radiates in a direction substantially perpendicular to the axis of the optical fiber, and wherein the optical fibers are connected by a second end to a source from light.
- This bodywork element is characterized in that the optical fibers are organized in strand over all or part of their length.
- the organization of the strand fibers in which the fibers are wound helically around the axis of the strand forming a cable, allows the axial movement of the fibers relative to each other when the cable undulates to follow the journey imposed on him. Playing on the number of turns per meter made by the fibers around the axis of the strand allows a greater or lesser bending of the cable.
- optical fiber or light guide means here an elongated transparent or translucent fiber having a refractive index higher than the ambient air, inside which light rays move in a controlled manner in one direction.
- general axial joint from a first end of the fiber having an entrance surface near which are disposed one or more light sources, to an exit surface from which the light rays emerge.
- the propagation of light inside the light guide is made by successive internal reflections of the light rays on the internal faces of the fiber called internal reflection faces.
- the exit surface may be formed by the face or section opposite to the entrance face or alternatively by a side face of the light guide.
- the term diffusing fiber is understood to mean an optical fiber in which the light exit surface is formed by the radial surface of the fiber. This surface, which occupies all or part of the surface of the fiber, is substantially parallel to the general direction of progression of the light in the fiber. Thus, for an optical fiber, the light emerges in a direction substantially radial and perpendicular to the axis of the fiber.
- a diffusing optical fiber therefore makes it possible to distribute a substantially constant luminous flux at any point on the exit surface of the diffusing part.
- a diffusing optical fiber may use different technologies and known as such.
- a first technique is to treat the surface of the fiber considered as the exit surface, so as to make it rough. The roughnesses are then so many reflective surfaces allowing part of the light to escape from the light guide to the outside.
- This technology is inexpensive, and is very effective for diffusing light guides of short length, in practice for lengths less than 3m. It also allows make diffusing as the only part of the fiber used for lighting.
- Another technology involves doping the material forming the fiber with microscopically sized reflective particles. This technology makes the diffusion of light more uniform.
- the bodywork element according to the invention also comprises, alone or in combination, the following characteristics:
- the optical fibers are arranged in a sheet in the portion of the optical fibers resting on the support, and the optical fibers are arranged in a strand in the section of fibers between the light source and the portion resting on the support.
- the optical fibers of the web portion constitute the weft yarns of a woven element.
- the layer of optical fibers resting on the support is interposed between said support and a body formed of a transparent plastic material.
- the body is covered on one of its faces with a semi transparent decoration constituted by:
- a metal deposit with a thickness of less than 200 nanometers, and preferably less than 100 nanometers, and even more preferably less than 75 nanometers, or
- thermoformed film deposited by overmolding with a thickness of between 175 micrometers and 475 micrometers.
- a layer of light-emitting material opaque and patterned is interposed between the inner face of the body member body and the layer of fibers resting on the support.
- the optical fibers are arranged in strand over their entire length. In the portion of the optical fibers resting on the support, the optical fiber strand is surrounded by a sheath formed of a transparent plastic material. - In the section of optical fibers between the light source and the support, the fiber optic strand is surrounded by a sheath that does not allow the light to pass.
- the optical fibers are not diffusing.
- the optical fibers have a diameter of between 250 and 500 micrometers.
- the fibers forming the strand are wound helically around the axis of the strand by making a number of turns per meter between 10 and 100.
- the light source is offset from the support, and located on an inner side of the bodywork in an area away from external aggression.

- FIG. 1 represents a plurality of optical fibers 5 organized in a strand.
- the optical fibers 5 have a diameter of between 250 and 500 micrometers. They are wound around the axis of the strand in a helical manner by making a number of turns per unit length P around this axis. In this case, the fibers are about 10 to 100 turns per meter. This number of turns is adjusted experimentally as a function of the diameter of the fibers, the number of fibers composing the strand, and as a function of the radii of curvature observed on the path followed by the strand.
- FIG. 2 illustrates a first example of implementation of the invention in which, at a first end 50, the optical fibers 5 are organized into a sheet 52.
- This part 50 represents the part of the fibers intended for serve as illuminating area.
- a light source 51 is disposed at a second end remote from the first end.

- the fibers 5 of the web 52 may form a woven, wherein the fibers 5 form the son of chains, held by weft son 53 preferentially translucent.
- the total length of the fibers 5 is adjusted to continuously cover the path from the light source 51 to the end of the portion 50 forming the illuminated area.
- the bodywork element 1 comprises a support 3 fixed to a structural part 8.
- the support 3 is preferably made using an opaque material such as for example a filled polypropylene such as that which is commonly used in the automotive industry to make the openings or the inserts on the body such as than the hulls of mirrors.
- the support 3 can also be confused with the structural part 8 in which the bodywork element is integrated.
- the portion of the end 50 of the organized ribbon fibers 52 rests on the surface of the support 3 on the exposed side towards the outside of the vehicle.
- the fiber web 52 may be covered by a body 2, transparent to light.
- the body 2 is formed using an amorphous material, such as, for example and not exclusively, polycarbonate (PC), polymethyl methacrylate (PMMA), acrylonitrile Butadiene Translucent Styrene (ABS) or Acrilonitrile Styrene Acrylate (ASA), acrilonitrile styrene (SAN), a mixture of Acrilonitrile Styrene Acrylate and Polycarbonate, a mixture of Poolycarbonate and Polyethylene terephthalate).

- the shape of the body is then adapted at will to harmonize with the shape of the body on which, or around which, the body member 1 is disposed.
- the thickness of the body is not limited, and is determined according to the shape and rigidity of the bodywork element 1 that is sought to achieve; it can vary from a few millimeters to one or even two centimeters.
- the body 2 is fixed by means (not shown) on the support 3.
- the bodywork element 1 is used here to enhance the line of a door bottom.
- the support 3 is fixed on a structural part of the body 8.
- the portion 50 of the optical fibers organized in sheet 52 is interposed between the support 3 and the body 2.
- a decorative panel 81 completes the lower part of the door bottom.
- FIG. 4 illustrates the case in which the bodywork element 1 is illuminated by the only external light such as daylight.
- the entire bottom door gives the outside look a uniform hue.
- the light source 51 When the lighting conditions weaken, the light source 51 is activated, and the bodywork element appears as a uniformly illuminated surface as shown in Figure 5. Due to the origin of the light rays , the body element 1 has a backlit appearance. A pattern 61 also appears.
- FIG. 6 makes it possible to highlight the respective positions of the elements represented in FIG. 3 and comprising, in the direction going from the inside to the outside of the vehicle, the support 3, the optical fibers 5 organized in a sheet diffusing light rays L, and the body 2.
- Figures 6 to 10 illustrate particular embodiments of this first embodiment of the invention.
- Figure 7 illustrates the case in which it seeks to reveal a particular pattern 61, when the light device 51 is activated.
- a layer of opaque material 6 not allowing the light to pass, is deposited on the internal face of the support 2.
- This layer of opaque material 6 filters the light coming from the sheet 52 in which the fibers are diffusing and leaves appear a graphic pattern 61 such as a logo or a monogram.
- the layer of opaque material 6 may be an opaque paint layer in which the pattern is obtained by laser scraping, or a part bonded directly to the inner face of the body 2.
- the support 3 comprises on its outer face, that is to say on the face of the support 2 looking outside the vehicle and visible from the outside, a semitransparent decorative coating 4.
- the decorative coating 4 has a first aesthetic function which is to give a tint to the body member 1, so that the outer surface of this element integrates with adjacent body parts.
- the chosen color may be identical to the color of the body parts, or of different color, if one wishes to raise a particular line or profile.
- the second function of the decorative coating 4 is to let all or part of the light emitted by the sheet of fibers. It is therefore important to choose a thin coating.
- the paint will preferably comprise a primer layer whose thickness is between 5 and 10 micrometers, a tinted base layer whose thickness is between 2 and 3 microns and a layer of transparent protective varnish, advantageously glossy or satin, the thickness of which is between 5 and 10 micrometers.
- the total thickness of the paint should not exceed 20 micrometers. It may also cover the body 2 of the bodywork element of a metal deposit obtained, for example, by the technique of physical vapor deposition, and whose thickness is, depending on the metal used , less than 200 nanometers, and preferably less than 100 nanometers, and even more preferably less than 75 nanometers.
- the chosen material may be, depending on the desired effect, chromium, nickel, gold, silver, or aluminum.
- Another technique is to overmold a translucent colored film having a thickness of between 175 micrometers and 475 micrometers on the outer face of the body 2.
- a third function of the decorative coating 4 is to return, as far as possible, the incident light from the outside natural light so as to mask the internal organs of the bodywork member 1 such that the fiber web 52, the logo or the monogram, or the support 3.
- This protective coating 7 may usefully be made, in known manner, with the aid of a transparent thermoplastic film.
- FIG. 9 represents the case in which the decorative coating 4 is disposed on the inner face of the support 2 facing the inner part of the vehicle.
- This arrangement enhances the protection of the decorative coating.
- it limits the semi-reflecting mirror effect mentioned above.
- It also makes it possible to confer a particular depth effect on the decoration, which effect can be amplified by varying the transparency or the pigmentation of the material used to make the support.
- Figure 10 shows the different parts forming the body member 1 in a second embodiment of the invention.
- This embodiment differs from the previous in that, in the portion 50 of the fibers coming to rest on the support 3, the fibers are organized in strand 54.
- the optical fibers are arranged in strand over their entire length, from the end of the portion 50 to the light source 51.
- the fibers are treated to allow the diffusion of light in a direction substantially perpendicular to the axis of the fibers.
- the fiber section 56 flowing between the light source 51 and the portion 50 resting on the support 3 is enclosed in an opaque sheath 57.
- the fibers may be covered, in the visible part 50, with a transparent body 2.
- this part 50 it is also possible, in this part 50, to enclose the fiber strand 54 in a sheath 55 of transparent thermoplastic material to maintain the fibers and isolate external aggressions as shown in FIG. Figure 11, which is a sectional view along AA of the fiber strand in the portion 50.
- the strand surrounded by its protective sheath 55 is preheated so as to allow the shaping necessary to obtain the desired graphics. Once this form is reached, the pattern obtained freezes by allowing the thermoplastic material 55 surrounding the strand 54 to cool.
- Figure 12 shows the bodywork element formed of the assembly of the parts of Figure 10 lit in daylight. Its appearance is identical to that shown in FIG. 4.
- FIG. 13 shows the light effect, here in the form of a line of light, produced by this same bodywork element when the light source 51 is activated. .
- the fiber strand of the section 50 can easily be brought into a region of the body protected from external aggression, deported with respect to the element body 1 itself, and where are disposed the light source 51 and the electrical connections.
- the fibers are not diffusing in this section 50.
