Description
本発明は、樹脂芯材の表面に表皮材を貼り合わせた構成の車両用内装部品のうち、その表皮材の表面に縫い目模様としてのステッチを有するものに関し、特に、ステッチによる立体感の表現効果が高く、ステッチ周辺での外観不良の発生防止と製造工数の削減を図れるようにしたものである。
The present invention relates to a vehicle interior part having a structure in which a skin material is bonded to the surface of a resin core material, and has a stitch as a seam pattern on the surface of the skin material, and in particular, an effect of expressing a three-dimensional effect by stitching. Therefore, it is possible to prevent the appearance defects around the stitches and reduce the number of manufacturing steps.
従来、車両用内装部品としては自動車のドアトリムが良く知られており、この種のドアトリムでは、その見栄えの向上を図ること等を目的として、樹脂芯材の表面に合成皮革やレザー等の表皮材を貼り合わせている。
Conventionally, automobile door trims are well known as interior parts for vehicles. For the purpose of improving the appearance of these types of door trims, skin materials such as synthetic leather and leather are used on the surface of the resin core. Are pasted together.
また、前記のような樹脂芯材と表皮材の貼り合せ品からなるドアトリム（車両用内装部品）では、その更なる見栄えの向上を図る加飾手段として、表皮材の表面にステッチを形成している。この種のステッチを有する従来のドアトリムとして利用可能な加飾パネルは例えば、特許文献１に開示されている。この特許文献１の加飾パネルは、芯材（６）の表面側に表皮材（１）を貼り合わせた形態になっていて、その表皮材（１）の表面にステッチ（５）を形成している。
Moreover, in the door trim (vehicle interior part) which consists of a bonded product of the resin core material and the skin material as described above, stitches are formed on the surface of the skin material as a decoration means for further improving the appearance. Yes. A decorative panel that can be used as a conventional door trim having this type of stitch is disclosed in Patent Document 1, for example. The decorative panel of Patent Document 1 has a form in which a skin material (1) is bonded to the surface side of a core material (6), and stitches (5) are formed on the surface of the skin material (1). ing.
しかし、特許文献１の加飾パネルでは、ベースパネル（３）に対して表皮材（１）を縫い付ける構成、および、ベースパネル（３）を芯材（６）の凹溝（符号なし）に配置する構成（同文献の図２を参照）を採用している。このため、特許文献１の加飾パネルをドアトリム等の車両用内装部品に適用した場合には、その車両用内装部品の製造工程としては少なくとも３工程、すなわち、ベースパネル（３）に対して表皮材（１）を縫い付けることによりステッチ（５）を形成する工程と、ステッチ形成後の表皮材（１）付きベースパネル（３）を芯材（６）の前記凹溝に配置することでステッチ（５）の位置を調整する工程と、芯材（６）に対する表皮材（１）の貼り合せ工程とが必要になり、製造工数が多くなるという問題点がある。
However, in the decorative panel of Patent Document 1, a structure in which the skin material (1) is sewn to the base panel (3), and the base panel (3) is formed into a concave groove (not indicated) in the core material (6). The arrangement to be arranged (see FIG. 2 of the same document) is adopted. For this reason, when the decorative panel of Patent Document 1 is applied to an interior part for a vehicle such as a door trim, at least three processes for manufacturing the interior part for the vehicle, that is, the skin with respect to the base panel (3) The step of forming the stitch (5) by sewing the material (1) and the base panel (3) with the skin material (1) after the stitch formation is arranged in the concave groove of the core material (6). The process of adjusting the position of (5) and the bonding process of the skin material (1) with respect to the core material (6) are required, and there is a problem that the number of manufacturing steps increases.
また、特許文献１の加飾パネルでは、前述の通り、ベースパネル（３）を芯材（６）の凹溝（符号なし）に配置する構成（同文献の図２を参照）を採用しているため、そのように配置した状態において、ベースパネル（３）と芯材（６）の凹溝（符号なし）との間に空隙（同文献１の図２を参照）が生じることは避けられず、かかる空隙に表皮材（１）の一部が落ち込むことで、ステッチ（５）の横に意図しない凹筋模様が現れてしまう等、ステッチ周辺での外観不良が多発し易いという問題点もある。
Moreover, in the decorative panel of patent document 1, as above-mentioned, the structure (refer FIG. 2 of the literature) which employ | adopts arrange | positions a base panel (3) in the ditch | groove (without code | symbol) of a core material (6) is employ | adopted. Therefore, it is unavoidable that a gap (see FIG. 2 of the same document 1) is generated between the base panel (3) and the concave groove (not shown) of the core member (6) in such a state. In addition, since a part of the skin material (1) falls into such a gap, an unintended concave streak pattern appears on the side of the stitch (5), resulting in frequent appearance defects around the stitch. is there.
さらに、特許文献１の加飾パネルによると、ベースパネル（３）を芯材（６）の凹溝（符号なし）に配置したときに、ベースパネル（３）の表面と芯材（６）の表面が略一致する構成になっているため、ステッチ（５）両側に位置する表皮材（１）が芯材（６）の凹溝に引き込まれることによる高低差の発生は期待できず、ステッチによる立体感の表現効果は低い。
Furthermore, according to the decorative panel of Patent Document 1, when the base panel (3) is disposed in the concave groove (no symbol) of the core material (6), the surface of the base panel (3) and the core material (6) Since the surface is substantially coincident, the skin material (1) located on both sides of the stitch (5) cannot be expected to generate a height difference due to being pulled into the concave groove of the core material (6). The three-dimensional effect is low.

以下、本発明を実施するための最良の形態について、添付した図面を参照しながら詳細に説明する。
Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.
図１（ｄ）のドアトリムＤＴ（車両用内装部品）は、図示しない車体パネルの室内面側に装着されるものであり、車体パネルに対して着脱可能に取付けられる図１（ａ）の樹脂芯材１と、樹脂芯材１の表面に設けた凹溝１Ａと、図１（ｂ）のように樹脂芯材１の表面に貼り合わせた表皮材２と、を備え、その表皮材２の表面に縫い目模様としてのステッチ３（図１（ｃ）（ｄ）参照）を形成してある。このステッチ３は、樹脂芯材１の表面に表皮材２を貼り合わせた状態で、凹溝１Ａに沿って表皮材２を樹脂芯材１に直接縫い付ける方式によって、その凹溝１Ａ内に形成したものである。
The door trim DT (vehicle interior part) in FIG. 1 (d) is mounted on the interior side of a vehicle body panel (not shown) and is detachably attached to the vehicle body panel in FIG. 1 (a). 1, a groove 1 </ b> A provided on the surface of the resin core 1, and a skin material 2 bonded to the surface of the resin core 1 as shown in FIG. A stitch 3 (see FIGS. 1C and 1D) is formed as a seam pattern. The stitch 3 is formed in the concave groove 1A by a method in which the skin material 2 is directly sewn to the resin core material 1 along the concave groove 1A in a state where the skin material 2 is bonded to the surface of the resin core material 1. It is a thing.
樹脂芯材１表面への表皮材２の貼り合せは、手作業（手貼り）のほか、成形装置を使うことができる。成形装置での貼り合せでは、例えば、第１の型（下型）の型面上に樹脂芯材１をセットする一方、その第１の型の型面に対向する第２の型（上型）の型面上に表皮材２をセットするか、あるいは、いずれか一方の型の型面上に樹脂芯材１と表皮材２を重ねてセットした状態で、両型を相対的に接近させること（以下「型締め」という）により樹脂芯材１と表皮材２を圧着する方式で、樹脂芯材１表面への表皮材２の貼り合せを行うことができる。
The bonding of the skin material 2 to the surface of the resin core material 1 can be performed manually (manually) or using a molding apparatus. In the bonding with the molding apparatus, for example, the resin core material 1 is set on the mold surface of the first mold (lower mold), while the second mold (upper mold) facing the mold surface of the first mold. The skin material 2 is set on the mold surface of), or the molds of either one of the molds are set in a state where the resin core material 1 and the skin material 2 are overlapped, and the two molds are brought relatively close together. In this manner (hereinafter, referred to as “clamping”), the skin material 2 can be bonded to the surface of the resin core material 1 by the method in which the resin core material 1 and the skin material 2 are pressure-bonded.
また、前記成形装置での貼り合せでは、前記型締めの際に、第１の型の型面とこれに対向する第２の型の型面とで構成されるキャビティ内のエアーをバキューム装置で抜くことにより、キャビティ内に存在する表皮材２の一部が樹脂芯材１表面の凹溝１Ａ内に入り込むように成形することができる（以下「第１の成形方式」という）。また、前記型締めの際に、樹脂芯材１表面の凹溝１Ａに対応する突起で表皮材２の一部を凹溝１Ａ内に押し込むことにより、キャビティ内に存在する表皮材２の一部が樹脂芯材１表面の凹溝１Ａ内に入り込むように成形してもよい（以下「第２の成形方式」という）。この第１、第２の成形方式は、単独で採用するほか、併用も可能である。
Further, in the bonding by the molding apparatus, when the mold is clamped, the air in the cavity formed by the mold surface of the first mold and the mold surface of the second mold facing the first mold surface is vacuumed by the vacuum device. By pulling out, it is possible to mold so that a part of the skin material 2 existing in the cavity enters the concave groove 1A on the surface of the resin core material 1 (hereinafter referred to as “first molding method”). Further, when the mold is clamped, a part of the skin material 2 is pushed into the concave groove 1A by a projection corresponding to the concave groove 1A on the surface of the resin core material 1, thereby a part of the skin material 2 existing in the cavity. May be molded so as to enter into the concave groove 1A on the surface of the resin core material 1 (hereinafter referred to as “second molding method”). The first and second molding methods can be used alone or in combination.
前記のような成形装置や手作業（手貼り）による樹脂芯材１表面への表皮材２の貼り合せにおいては、例えばホットメルト接着材等の接着材を使用することができる。これとは別に、そのような接着材を使用しない方式、例えば、樹脂芯材１の表面を加熱溶融させるとともに、溶融した樹脂芯材１の表面に表皮材２を押し付けることにより、樹脂芯材１と表皮材２を圧着する方式を採用することも可能である。
In the bonding of the skin material 2 to the surface of the resin core material 1 by the above-described molding apparatus or manual work (manual bonding), for example, an adhesive such as a hot melt adhesive can be used. Apart from this, a method in which such an adhesive is not used, for example, by heating and melting the surface of the resin core material 1 and pressing the skin material 2 against the surface of the molten resin core material 1, It is also possible to adopt a method in which the skin material 2 is crimped.
前記第１又は第２の成形方式によって成形された表皮材１表面の凹み４（図１（ｄ）参照）、すなわち、表皮材２の一部が樹脂芯材１表面の凹溝１Ａ内に入り込んでいる箇所は凹溝１Ａに沿ってライン状になっており、このようなライン状の凹み４は、樹脂芯材１に対する表皮材２の縫い付けガイドとして利用することができ、これにより、縫い目模様としてのステッチ３の蛇行を防止し、蛇行の少ない安定したステッチラインを得ることができる。
The dent 4 on the surface of the skin material 1 formed by the first or second molding method (see FIG. 1D), that is, a part of the skin material 2 enters the concave groove 1A on the surface of the resin core material 1. The protruding portion is formed in a line shape along the concave groove 1A, and such a line-shaped recess 4 can be used as a sewing guide for the skin material 2 to the resin core material 1, thereby providing a seam. It is possible to prevent the meandering of the stitch 3 as a pattern and obtain a stable stitch line with little meandering.
樹脂芯材１に対する表皮材２の縫い付けについてはミシン（縫製機）を使用することができる。この場合は、先に説明したライン状の凹み４（表皮材２の一部が樹脂芯材１表面の凹溝１Ａ内に入り込んでいる箇所）に沿ってミシンのガイドバーを移動させ、移動するガイドバーでミシン針を誘導する等、凹み４のガイド機能を利用することにより、縫い目模様としてのステッチを凹溝１Ａ内に形成してもよい。
A sewing machine (sewing machine) can be used for sewing the skin material 2 to the resin core material 1. In this case, the guide bar of the sewing machine is moved along the line-shaped recess 4 (a portion where a part of the skin material 2 enters the recess groove 1A on the surface of the resin core material 1) as described above. A stitch as a stitch pattern may be formed in the concave groove 1A by utilizing the guide function of the recess 4 such as guiding a sewing needle with a guide bar.
図１（ａ）のドアトリムＤＴ（車両用内装部品）では、樹脂芯材１の裏面（表皮材２を貼り付けていない面）を凹凸のないフラットな面として構成しているが、図２に示したように、そのような樹脂芯材１の裏面には、樹脂芯材１表面の凹溝１Ａの凹みに合わせて同図のように出っ張った形態の凸条部５を設けてもよい。この凸条部５もまた、先に説明したライン状の凹み４と同じく、樹脂芯材１に対する表皮材２の縫い付けガイドとして利用することで、ステッチラインの安定に寄与する。なお、この凸条部５と先に説明したライン状の凹み４は、縫い付けガイドとして、単独で採用するほか、併用することも可能である。
In the door trim DT (vehicle interior part) of FIG. 1A, the back surface of the resin core material 1 (the surface on which the skin material 2 is not attached) is configured as a flat surface without unevenness. As shown, the back surface of such a resin core material 1 may be provided with a ridge 5 having a protruding shape as shown in FIG. This ridge 5 also contributes to the stability of the stitch line by being used as a sewing guide for the skin material 2 with respect to the resin core material 1, similarly to the line-shaped dent 4 described above. In addition, this ridge part 5 and the line-shaped dent 4 demonstrated previously are employable independently as a sewing guide, and can also be used together.
以上説明した本実施形態のドアトリムＤＴでは、その具体的な構成として、樹脂芯材１の表面に設けた凹溝１Ａに沿って表皮材２を樹脂芯材１に直接縫い付けることにより、表皮材２の表面に縫い目模様としてのステッチ３を形成したため、そのステッチ３の周辺では、ステッチ３両側に位置する表皮材２が樹脂芯材１の凹溝１Ａ内に引き込まれることで高低差が発生するため、ステッチ３による立体感の表現効果が高い。
In the door trim DT of the present embodiment described above, as a specific configuration, the skin material 2 is directly sewn to the resin core material 1 along the concave groove 1A provided on the surface of the resin core material 1, thereby the skin material. Since the stitch 3 as a seam pattern is formed on the surface of 2, the skin material 2 located on both sides of the stitch 3 is drawn into the concave groove 1A of the resin core material 1 in the vicinity of the stitch 3 to cause a height difference. Therefore, the effect of expressing the three-dimensional effect by the stitch 3 is high.
また、本実施形態のドアトリムＤＴによると、その具体的な構成として、樹脂芯材１の表面に表皮材２を貼り合わせた状態で、樹脂芯材１の表面に設けられている凹溝１Ａに沿って表皮材２を樹脂芯材１に直接縫い付ける構成を採用した。このため、２工程、すなわち、樹脂芯材１に対する表皮材２の貼り合せ工程と、その後に行われる表皮材２の縫い付け工程だけで、ステッチ３を有するドアトリムの製造が可能となる点で、製造工数の削減を図れる。また、ステッチ３の形成にあたり、従来の技術で説明したベースパネルを使用せず、表皮材２を樹脂芯材１に直接縫い付ける方式を採用したので、そのようなベースパネルの使用によって発生し得る従来の外観不良（具体的にはステッチ３の横に意図しない前述の凹筋模様が現れること）が生じるおそれもなく、ステッチ周辺での外観不良の発生防止も図れる。
Further, according to the door trim DT of the present embodiment, as a specific configuration thereof, in the state where the skin material 2 is bonded to the surface of the resin core material 1, the groove 1 </ b> A provided on the surface of the resin core material 1 is provided. A configuration was adopted in which the skin material 2 was sewn directly to the resin core material 1. For this reason, the door trim having the stitches 3 can be manufactured in only two steps, that is, the step of bonding the skin material 2 to the resin core material 1 and the step of sewing the skin material 2 performed thereafter. Reduce manufacturing man-hours. Further, in forming the stitch 3, the base panel described in the prior art is not used, but a method of directly sewing the skin material 2 to the resin core material 1 is employed. There is no risk of a conventional appearance defect (specifically, the above-mentioned unintentional concave streaks appear next to the stitch 3), and the appearance defect around the stitch can be prevented from occurring.
本発明は、以上説明した実施形態に限定されるものではなく、本発明の技術的思想内で当分野において通常の知識を有する者により多くの変形が可能である。例えば、本発明はドアトリム以外の車両用内装部品にも適用できる。
The present invention is not limited to the embodiments described above, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention. For example, the present invention can be applied to vehicle interior parts other than door trims.
