CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Patent Applications 61/540,275 filed September 28, 2011 and 61/623,889 filed April 13, 2012, the contents each of which are incorporated herein by reference thereto.
BACKGROUND
[0002] This invention relates to an illuminated structure and more particularly, the invention relates to a method for providing illuminated stitching wherein the stitching provides an illuminated component.
[0003] Currently, most stitching found in an article of manufacture is of the functional variety, wherein 2 or more pieces of material (e.g., leather, vinyl, thermoplastic polyolefin (TPO), cloth, poly urethane skin, or other man made or natural skin items, etc.) are cut from a pattern and sewn together (cut-n-sew) prior to being wrapped around a component such as a seat cushion, head rest, arm rest, console lid, instrument panel, door trim, console, substrate, etc.
[0004] A simulated functional or non-functional stitch has been used in some applications; however, the ability to offer a simulated stitch with a changing color or illumination is not production feasible at this time. Additionally, more manufactures are requesting a real or "live" stitch be used on decorative components to provide the look and feel of a true cut-n-sew component at reduced cost. Still further, the ability to change the appearance of functional stitching is also desirable.
[0005] Accordingly, it is desirable to provide an illuminated stitch (functional or non-functional) on a stitched component. SUMMARY OF THE INVENTION
[0006] A method of illuminating a component, having an outer skin layer, the method including the steps of: forming a seam of the outer skin layer; and locating an elongated light conducting medium in the seam.
[0007] Alternatively, the component can also consist of a hard panel only wherein the light conducting medium is attached to the backside of the component via tape or decorative stitching that penetrates the hard panel. A continuous or discontinuous channel, molded-in or secondarily trimmed into the panel serves as a means of transmitting the light from the back to front side of the panel.
[0008] A trim component having a seam wherein an elongated light conducting or light generating medium is located in the seam.

[0022] 1) Use of a light pipe, fiber optic cable, or other light conducting medium and/or generating medium as a thread that is sewn into a trim component that produces an illuminated stitch when connected to a light source. [0023] When the lighting source is used as a thread as mentioned above, the light conducting medium should be of a diameter and construction to be passed through a needle within a chain stitch or lock stitch type sewing machine. Chain stitch type sewing is the preferred method, as the thread is subjected to much less abrasion and torsion during stitching. Of course, other stitch types can be used and are contemplated to be within the scope of various embodiments of the present invention.
[0024] 2) Light pipe, fiber optic cable, or other light conducting medium or light generating medium that is sewn into the seam which either joins two materials together or produces a visual effect that simulates the joining of two materials. When connected to a light source, the light conducting medium emits light to illuminate the join seam produced by the sewing operation.
[0025] When encapsulated within the join seam as described in second embodiment above, the light conducting medium can be of any number of diameters and constructions to provide the degree of light intensity and visual effect required by the manufacturer. For example, when encapsulated as part of deck seam design, the following assembly steps can be followed:
[0026] Step a) Use single or double needle machine to join two pieces of material together. Thread tension on inside seam should be reduced to allow joined materials to separate slightly when placed under tension.
[0027] Step b) Fold top layer of material back upon itself and stitch to join seam, outside of initial join seam stitch, produced a deck type fold in the materials.
[0028] Step c) Insert light conducting medium between the two materials at the join seam.
[0029] As mentioned above and will be discussed herein, the light conduction medium can be incorporated into the seam during or after sewing and in one embodiment, the medium is integrated during the sewing process to avoid damaging the medium during post-seam sewing installation. Accordingly, one exemplary embodiment is directed to incorporating the side emitting fiber optic cable during the sewing process as opposed to inserting it after the seams have been made.
[0030] In the methods described above and herein, light intensity and color can be varied by the end consumer based on individual taste. Illumination timing and frequency can also be tied, but not limited, to vehicle function(s), such as turn signal indicators, music volume, vehicle speed, engine RPM and/or acceleration. Accordingly and in various alternative embodiments, the illumination of the light conducting medium and/or generator can be coupled to a controller or microcontroller 51 (see the dashed lines of FIGS. 15A, 15B, 21A and 21B) of the aforementioned vehicle functions (illustrated schematically by box 53) such that the illumination of the medium is varied accordingly. Still further, the controller or microcontroller 51 may be used to vary the illumination in non-vehicular applications wherein other functions (e.g., music volume, beat, detected light, etc. or any other application wherein variation of the illumination is desired) are used to vary the illumination.
[0031] Turning now to the drawings, wherein to the extent possible like reference numerals are utilized to designate like components throughout the various views and various embodiments of the present invention. As shown throughout the FIGS., it is seen that an interior portion 12 of a vehicle or any other manufacturable component is illustrated. In one implementation interior portion 12 is a portion of an instrument panel of a vehicle.

FIGS. 9 and 10 utilize a light conducting and/or generating medium 10 behind the double needle stitching with or without join seam 20 illumination as an option. Also illustrated is that multiple or numerous light conducting and/or generating mediums 10 are employed in various locations proximate to the seams and/or the related threads. [0044] In the attached FIGS, some but not all multiple combinations of side emitting fiber optic cable 10 are illustrated. Accordingly, numerous configurations are possible and are not limited to the specific examples described herein. As mentioned, herein the threads used for the seams (functional or non-functional) can be clear multi- strand or monofilament or can be pigmented depending on the desired effect. Moreover, multiple colors are possible as are lighting from both ends of the cable 10 (same color or different). Still further, the colors can be dynamically changed through lensing arrangements, redundant (different) light sources, and by the use of different lenses (fixed or moving).
[0045] FIGS. 11 and 12 illustrate the possibility of illuminating a double and single needle non-functional stitch 33 using a light conducting and/or generating medium 10 which is attached directly behind the stitch seam on the backside of the part by for example, a retainer tape 26.

Covering 46 also includes a sewable portion 45 located proximate to portion 44. As with the previous embodiments, this design can be sewn into numerous seams the way any piping or welting material could be. Also, the perforations 48 can be numerous shapes for added impact or effect. In addition, perforated covering 46 may also be translucent and/or opaque to provide still other lighting effects when illuminated by the light conducting or generating medium 10.
[0054] Accordingly and in this embodiment, the side emitting fiber optic cable 10 can be wrapped with a sew-able material creating piping, or welting. When this item is sewn into a seam and illuminated, it can create dramatic effects on many different products.
[0055] Referring now to FIGS . 18 A- 18C another alternative
embodiment is illustrated. Here the light conducting or generating medium 10 (e.g., side emitting fiber optic cable or any other equivalent device) is coextruded with a material 50 that can be positioned within a seam 52 located between two materials 15 that are sewn together at seam 52. In this embodiment, the shape of the coextruded material (e.g., light conducting or generating medium 10 and material 50) can be designed to affect the shape of the sewn seam 52. Still further numerous fiber optic shapes of the light conducting or generating medium 10 can be used to provide different lighting effects as well as facilitating co-extrusion. Non-limiting configurations of such shapes are illustrated in FIGS. 18A-18C.
[0056] In addition, material 50 can comprise a softer material in order to facilitate sewing of seam 52 by passing threads 54 therethrough.
[0057] Referring now to FIG. 19 yet another alternative embodiment is illustrated.

Moreover and in one embodiment wherein the stitch is decorative only, the stitching is applied through the cover material 15 and the substrate 17. Accordingly and when translucent threads are used, light can be passed through them to the front by applying a light source to the back of the part.
[0060] As mentioned above, the light source 10 can be fixed to layers 15 with a separately molded (or extruded piece) 17, or with another component 57 (extruded or assembled, FIG. 20B) or with simple tape 59 (FIG. 20C). [0061] Referring now to FIGS. 21A and 21B a cross-sectional view of an illuminated component 12 in accordance with yet another alternative exemplary embodiment is illustrated. Here the light generator 34 is directly coupled to the translucent threads 30 such that light can be passed through them to the show surface or front 22. Accordingly and as mentioned above and in this embodiment, the threads themselves are the light conducting medium. This may be particularly useful in short runs or lengths of stitching wherein the light can be directly transmitted to the sewn stitch without a separate light conductor 10. In one non-limiting embodiment, the light generator 34 is an LED or any other equivalent structure. One non-limiting example of translucent threads 30 is a mono-filament material. FIG. 15B illustrates the illumination of the translucent threads 30 indicated by arrows 38. Still further, this embodiment may be combined with embodiments employing the light conducting medium 10 thus numerous combinations are possible.
