BACKGROUND OF THE INVENTION
The present invention relates to a vehicle interior member, more specifically, a substrate to be fixed to a predetermined position of the vehicle passenger compartment, consists of a skin material which is deposited on the front side outer surface of the base material, the cutting tool the base end portion obtained when cutting the substrate, the skin terminal of said skin material is relates to a vehicle interior member which is adapted to cover involving the back side outer surface of the substrate.
[0002]
[Prior art]
Various vehicle interior members are mounted in the passenger compartment of a vehicle such as a passenger car for the purpose of improving the texture of the passenger compartment. For example, the roof member to be mounted on the roof portion in the passenger compartment is a sheet-like material that is made of a resin or fabric having flexibility and is pasted on the roof portion in the past. It was a member of. However, as shown in FIG. 7, the roof member that has been practiced in recent years is pre-formed into an outer shape that matches the overall shape of the roof portion, and is easily assembled and mounted on the roof portion. Panel 10 is provided.
[0003]
Here, as shown in FIGS. 8 and 9, the roof panel 10 includes a base material 12 having a laminated structure in which glass fibers 16 and 16 are attached to both surfaces of a plate-like foam core material 14, and the base material 12. It is comprised from the skin material 18 attached to the front side outer surface (surface which faces a passenger compartment side) 12a. The roof panel 10 is formed on the basis of press molding technology, and the base material 12 supplied as a flat plate material is formed into a concavo-convex shape that matches the overall shape of the roof portion. It is manufactured by simultaneously applying the skin material 18 to the front outer surface 12a of the substrate 12. The base material 12 has a thickness of about 2 to 4 mm although there is some variation for each part, and the base material 12 is hot-pressed under the impregnation with a urethane-based adhesive and molded into the shape described above. The weight reduction and shape retention are achieved, and the rigidity of the outer surface portion is improved by the glass fibers 16 and 16 bonded to both outer surfaces of the foam core 14. The skin material 18 is made of synthetic resin, woven fabric represented by fabric, knit, or moquette, and has flexibility, and is exposed to the passenger compartment to improve the texture of the roof panel 10. It is.
[0004]
On the other hand, in vehicles such as passenger cars, it is possible to provide an opening window in the roof portion in accordance with user preference. Generally, a roof portion provided with such an opening window is referred to as a “sun roof” or “ It is called “Moon Roof”. In the roof panel 10 implemented in a vehicle provided with such an opening window, as shown in FIG. 7, the cut line CL is formed in a later process after the portion corresponding to the opening window is formed into a convex shape. It is necessary to open an opening 22 that matches the opening window by cutting the unnecessary portion 20 by making a cut along (FIG. 8).
[0005]
Here, the opening 22 is formed by the method illustrated in FIG. 9, for example. That is, after forming the base material 12 as described above and attaching the skin material 18 to the front outer surface 12a of the base material 12, only the portion in the vicinity of the cut line CL in the skin material 18 is peeled off from the base material 12. The cutting edge 24 of the cutting tool 24 such as a cutter is inserted along the cut line CL from the outside to make a cut, and thus the unnecessary portion 20 is cut away to form the opening 22. And the base material edge part 26 obtained when the said base material 12 is cut | disconnected with the said cutting tool 24 winds the skin terminal 28 of the said skin material 18 on the back side outer surface 12b of this base material 12, and adhere | attaches it. The outer skin terminal 28 is covered so as not to be exposed to the opening 22 (FIG. 10).
[0006]
[Problems to be solved by the invention]
However, the base material end portion 26 obtained by inserting the cutting tool 24 has an uneven surface, or a convex portion 30 such as a burr is easily formed on the edge in the thickness direction. Therefore, in the direct and close contact to entangle epidermal end end structure epidermal terminal 28 of the skin 18 relative to the base end portion 26, the presence of the projections 30 of the burrs appear in epidermis terminal 28 Thus, there is a problem that causes a decrease in texture and a decrease in touch (FIG. 10). In particular, since the base material 12 has a laminated structure in which the glass fibers 16 are adhered to both surfaces of the foamed core material 14, convex portions 30 formed of the edges of the glass fibers 16 are easily formed on the base material end portions 26. In addition to this tendency, when the cutting edge of the cutting tool 24 is worn and the cutting performance is deteriorated, this tendency appears more remarkably. Further, when a plurality of cutting tools 24 are used to make a cut in the base material 12, a step due to an attachment error or the like of each cutting tool 24 is formed in the base material end portion 26. In this case, However, the presence of the step appears on the skin terminal 28 as it is.
[0007]
Incidentally, the addition to the epidermis end end structure involving epidermis terminal 28 of the skin 18, for example, as shown in FIG. 11, the substrate end of the strip member 34 which is separately molded to the cross-sectional shape of the substantially U-shaped portion 26 An end portion structure that covers the base end portion 26 by being attached to the substrate is also implemented. However, in such an end structure, since the molding member 34 is exposed at the outer peripheral edge of the opening 22, the appearance is deteriorated in the end, and the problem of deterioration in texture cannot be solved preferably. .
[0008]
