Description

  The present invention relates to an automotive interior part and a method for manufacturing the same, and in particular, a two-layer base including a panel-side base material formed into a desired uneven shape and an indoor-side base material formed into a substantially flat product surface shape. Automobile interior parts that employ a material structure, with attachment parts such as clip mounting seats, harness clips, electrical harnesses, shock absorbing pads, etc., firmly sandwiched between the panel side substrate and the indoor side substrate The present invention relates to an automobile interior part that can be supported and can efficiently modularize accessory parts and a method for manufacturing the same.

  For example, as shown in FIG. 11, a molded ceiling 2 formed in a substantially curved shape is mounted on the indoor surface side of a roof panel 1 of an automobile, and this molded ceiling 2 has an appropriate shape retaining property and a roof. It is comprised from the base material 2a provided with the attachment rigidity to the panel 1, and the skin 2b laminated | stacked and integrated on the surface. Usually, the material of the substrate 2a is a resin sheet containing glass fibers, a fiber molded body in which glass fibers and resin fibers are accumulated in a mat shape, and formed into a plate shape by press molding, PPO (polyphenylene oxide) foaming A resin base material, a urethane resin base material, a PET non-woven fabric molded body, and the like are used, and as the skin 2b, a woven fabric, a non-woven fabric, a synthetic resin sheet, or the like is appropriately used.

  Furthermore, in order to attach the molded ceiling 2 to the roof panel 1, as shown in FIG. 12, a clip mounting seat 4 for mounting the panel mounting clip 3 is attached at a predetermined position on the back surface of the molded ceiling 2, The reactive hot-melt adhesive 5 is applied to the substrate 2a, and the clip mounting seat 4 is set and fixed thereon.

A conventional example of a structure for attaching a molded ceiling to a roof panel is described in detail in Patent Document 1.

Japanese Unexamined Patent Publication No. 2000-85486

  As described above, the conventional molded ceiling 2 uses the reactive hot-melt adhesive 5 as means for attaching the clip mounting seat 4, the harness clip 6 and the like to the molded ceiling 2, for example. Since the system adhesive 5 requires a curing time of about 24 hours, it has many problems such as inventory management and space securing. Further, since the base material 2a in the molded ceiling is molded so as to fit the shape of the roof panel 1, it is difficult to secure a space for accommodating an electrical harness, shock absorbing pad, etc., and is not suitable for a modular structure. There are some problems.

  The present invention has been made in view of such circumstances, and eliminates the reactive hot-melt adhesive 5 that requires a long curing time, adopts a two-layer substrate structure, and provides a space between two layers of substrates. By attaching and supporting at least some of the accessory parts such as clip mounting seats and harness clips, it can be manufactured in a short time, and it is easy to manage, such as easy inventory management and no need for space. And it aims at providing the interior component for motor vehicles which can respond effectively to modularization, and its manufacturing method.

  In order to solve the above-mentioned problems, the inventor has intensively studied, and as a conventional single-layer base material structure, the panel side base material located on the back side and the indoor side base material located on the front side have two layers. Reacts that require a long curing time by adopting a base material structure and sandwiching and fixing at least a part of accessory parts such as clip mounting seats, harness clips, electrical harnesses, and shock absorbing pads between the base materials The present inventors have found that a hot-melt adhesive can be eliminated and have completed the present invention.

  That is, the present invention is an automotive interior part that is composed of a base material molded into a required shape and is mounted on the interior surface side of a vehicle body panel, and the base material is a panel side that is molded into a desired uneven shape. A two-layer base material structure of a base material and an indoor base material formed into a substantially flat surface shape so as to form a product surface shape is adopted, and at least a part of the accessory parts attached to the interior part is It is sandwiched between the panel side base material and the indoor side base material.

  Furthermore, this method of manufacturing interior parts for automobiles heats the panel-side base material and the indoor-side base material sheet when the molding dies each having a vacuum suction mechanism are in an open state. After the softening treatment, the original sheet is put into the molding die, and the vacuum suction force is applied to the molding die, so that the one side of the original fabric sheet becomes the mold surface of the molding die. A flat product by forming a panel-side base material with a desired concavo-convex shape and vacuum-forming the other side of the original sheet along the mold surface shape of the other side mold A vacuum forming process of the base material for molding the indoor base material having the surface shape, and after opening the molding die, setting accessory parts on the indoor base material held on the lower mold , When part of the accessory is penetrated to the back side through the opening of the base material There is an accessory setting process for opening an opening in the panel-side base material held by the molding upper die, a piercing cut process for the base material, and a reheating treatment for the panel-side base material held by the molding upper die. The mold is clamped, and the panel side base material and the indoor side base material are pressure-bonded and integrated, and at least a part of the accessory is sandwiched and supported between the base materials. It consists of a process.

  Here, the interior parts for automobiles can be applied to roof trims, door trims, rear parcel shelves, floor trims, luggage trims, trunk trims, rear side trims, and the like. Furthermore, as a material of each base material (panel side base material located on the back side and indoor side base material located on the front side) constituting the two-layer base material structure, it is necessary to vacuum form into a required shape. Therefore, if it is a non-breathable and thermoformable material, a thermoplastic resin sheet, a thermoplastic resin sheet mixed with a reinforcing material such as glass fiber, or a closed cell type foamed resin sheet can be used. For example, a non-breathable film can be used if the material is breathable, such as non-woven mat material that is pressed and molded after glass fibers and thermoplastic resin fibers are collected into a mat shape, or an open-cell foamed resin sheet. It can be used by adding non-breathability by sticking.

  Then, the raw sheet that is the material of the panel side base material and the indoor side base material is first heat-softened and then set in a mold that is opened, and the raw sheet that is the material of the panel side base material A vacuum suction force is applied along the mold surface shape of the mold on one side, and the panel-side base material is vacuum-formed so as to have a desired uneven shape. On the other hand, the raw fabric sheet of the indoor side base material is also vacuum formed so as to have a substantially flat surface shape along the mold surface shape of the mold on the other side. At this time, if a structure in which the skin is applied to the surface of the indoor base material is adopted, the raw material sheet of the indoor base material and the raw material sheet of the skin are set so as to overlap each other. Both can be integrated by the residual heat of the sheet.

  Next, to set accessory parts such as clip mounting seats, harness clips, electrical harnesses, shock absorbing pads, etc., set the surface of the indoor base material held on the lower mold at a predetermined position. By using a setting jig, it is possible to easily set accessory parts at appropriate positions. Among the accessory parts, for example, the mounting seat body of the clip mounting seat, the harness clip body, and the like protrude toward the panel side through the opening of the panel-side base material. It is necessary to open an opening. In the opening process, an opening is formed by performing a piercing cut process on a predetermined portion of the panel-side base material in the previous step of the process of integrating the panel-side base material and the indoor side base material. After that, the panel side base material is subjected to reheating treatment, and the panel side base material and the indoor side base material for clamping the upper and lower molds are joined and integrated, and the panel side base material and the indoor side base material At least a part of the accessory can be sandwiched between and supported.

  Therefore, the automotive interior part and the manufacturing method thereof according to the present invention adopt a two-layer structure of a panel side base material and an indoor side base material as a base material structure of the interior part, and also provide a clip mounting seat, a harness clip, and an electrical equipment Because it has a configuration in which at least a part of accessory parts such as harnesses and shock absorbing pads are sandwiched and fixed between both base materials, the conventional reactive hot-melt adhesive that requires a long curing time can be abolished. You can fix the accessories in time. In addition, since the two-layer base material structure is used, the panel-side base material can be formed into a shape suitable for modularizing the accessory parts, and therefore, it is possible to effectively cope with modularization.

  As described above, according to the automotive interior part and the manufacturing method thereof according to the present invention, the panel-side base material formed into a desired concavo-convex shape and molded into a substantially flat surface shape so as to form a product surface shape. A two-layer base material structure with the indoor base material to be used is adopted, and at least a part of the accessory parts such as clip mounting seats, electrical harnesses, harness clips, shock absorbing pads, etc. are panel side base material and indoor side base material. These sandwiched parts can be firmly fixed by sandwiching them with the material, and the attached parts can be fixed in a shorter time than when using a conventional reactive hot-melt adhesive. Therefore, the inventory management is easy and the space is advantageous.

  Furthermore, for clip mounting seats, harness clips, shock absorbing pads, etc., the flange-shaped mounting plate is sandwiched between the two layers of the base material, and the electrical harness is embedded between the two layers of the base material, There is an effect that it is possible to surely prevent the accessory parts from falling off and to secure the attachment strength of the accessory parts. In addition, since the panel-side base material can be formed into a desired uneven shape, it is possible to effectively secure a space for storing the shock absorbing pad, a space for storing the harness clip, and the like, which is suitable for modularization of interior parts.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an automobile interior part and a method for manufacturing the same according to the present invention will be described below in detail with reference to the accompanying drawings. It should be noted that the gist of the present invention is as described in the scope of claims, and the contents of the embodiments described below are merely examples of the present invention.

  FIG. 1 to FIG. 10 show an embodiment of the present invention. FIG. 1 is a sectional view showing a configuration in which the present invention is applied to a molded ceiling. FIG. 2 is an enlarged sectional view showing a main part of the molded ceiling. 3 is an explanatory view showing an outline of a method for manufacturing the molded ceiling, and FIGS. 4 to 10 are explanatory views showing respective steps in the method for manufacturing the molded ceiling.

  1 and 2, an embodiment applied to a molded ceiling 10 mounted on the interior side of a roof panel 1 of a vehicle will be described. The formed ceiling 10 includes two-layer base materials 11 and 12 including a panel-side base material 11 formed into a desired concavo-convex shape and an indoor-side base material 12 having a substantially flat surface shape that forms a product surface shape. The skin 13 is affixed to the surface of the indoor base 12 and enhances the surface texture and feel.

  More specifically, the panel side base material 11 and the indoor side base material 12 are made of PP (polypropylene) resin mixed with glass fiber in consideration of shape retention, moldability, cost, etc. Polyester nonwoven fabric is used. And the said panel side base material 11 is shape | molded by the desired uneven | corrugated shape which has the recessed part 11a recessedly provided by the roof panel 1 side, and the convex part 11b which protrudes in the indoor side base material 12 side, The recessed part 11a, The location where the convex portion 11b is set takes into consideration the shape of the roof panel 1, that is, avoiding interference with the reinforcement portion 1a, and setting of a space for mounting a separate part, a harness accommodating space, or the like. Determined. Further, a hollow portion 14 is formed between the recess 11 a of the panel side base material 11 and the indoor side base material 12 as shown in the figure, and this hollow portion 14 is not affected by the shape of the roof panel 1. It is necessary to maintain the product surface shape of the molded ceiling 10 in a substantially flat shape, and the hollow portion 14 is also effective in heat insulation and sound insulation.

  The molded ceiling 10 accommodates and fixes a clip mounting seat 20 and a harness 30 for attachment to the roof panel 1 as accessory parts. Further, a structure in which the adhesive 15 is applied to the back surface of the recess 11 a of the panel-side substrate 11 and the molded ceiling 10 is bonded and fixed to the indoor surface of the roof panel 1 may be used in combination.

  By the way, the molded ceiling 10 according to the present invention can effectively cope with modularization, and can attach accessory parts such as the clip mounting seat 20 and the electrical harness 30 in a short time, and these accessory parts fall off. In order to make it possible to attach firmly without fear, it is a structural feature that at least a part of the accessory parts 20 and 30 is sandwiched and fixed by the two-layer base materials 11 and 12.

  That is, as shown in FIG. 2, if the holding structure of the clip mounting seat 20 and the electrical harness 30 is illustrated and described, the mounting plate 23 that extends to the base portion of the clip mounting seat body 22 that holds the clip 21 is the front and back surfaces thereof. Since it is clamped by the panel side base material 11 and the indoor side base material 12 from the side, the clip mounting seat 20 does not fall off and is firmly fixed. Furthermore, unlike conventional reactive hot melt adhesives, it can be fixed in a short time without requiring a long curing time (about 24 hours in the past).

  In addition, the electrical harness 30 is embedded in the space between the panel-side base material 11 and the indoor-side base material 12, and the electrical harness 30 is also firmly supported and fixed without falling off. Yes. Although not shown, for fixing the harness clip or the shock absorbing pad used in the structure for holding the electrical harness 30 on the rear surface of the molded ceiling 10, the flange-like mounting plate is attached to the panel side as in the above-described embodiment. If it clamps and fixes between the base material 11 and the indoor side base material 12, fixation will be completed easily and in a short time. Further, as shown in an enlarged view in FIG. 2, if the locking claw 24 is integrally formed on the lower surface 23a of the mounting plate 23 of the clip mounting seat 20 (the surface facing the indoor base material 12), the anchor effect is obtained. Thus, the support strength of the clip mounting seat 20 can be further strengthened.

  Thus, by forming the molded ceiling 10 into a two-layer structure of the panel-side base material 11 and the indoor-side base material 12, the product surface shape of the molded ceiling 10 is substantially the same regardless of the shape of the roof panel 1. It can be molded into a flat shape, can improve appearance and feel, and conversely, the molded ceiling 10 can increase the degree of freedom of the roof panel 1 without restricting the shape of the roof panel 1. . Further, as described above, the hollow portion 14 formed between the panel-side base material 11 and the indoor-side base material 12 can enhance heat insulation and sound insulation, and also sets a desired uneven shape. By doing so, it is possible to set a space for installing an accessory such as a shock absorbing pad, which is optimal for modularization.

  An outline of the method for manufacturing the molded ceiling 10 described above will be described with reference to FIG. 3, and each step of the manufacturing method will be described with reference to FIGS. 4 to 10. In FIG. 3, a molding apparatus 40 used when molding the molded ceiling 10 is provided so as to be able to be carried in and out of the molding upper mold 50, the molding lower mold 60, and the molding dies 50, 60 that can move up and down.
