Description

この発明は、基材と表皮材との間で発泡成形される発泡体を備えた車両内装部材に関するものである。   The present invention relates to a vehicle interior member provided with a foam that is foam-molded between a base material and a skin material.

車両の乗員室内には、インストルメントパネル、フロアコンソール、コンソールリッド、ドアパネル等の車両内装部材が配置されている。インストルメントパネルは、乗員室側の後側部分とデフロスタの空気吹き出し口等が設けられるフロントウィンドウ側の前側部分とで表面外観が異なるように構成されることがある。例えばインストルメントパネルは、硬質な基材および柔軟な表皮材の間に弾力性を有する発泡体を配設した３層構造で後側部分が構成される。また、インストルメントパネルは、前側部分が硬質な基材のみからなる１層構造となっている。   Vehicle interior members such as an instrument panel, a floor console, a console lid, and a door panel are arranged in the passenger compartment of the vehicle. The instrument panel may be configured so that the surface appearance is different between a rear portion on the passenger compartment side and a front portion on the front window side where an air outlet of the defroster is provided. For example, the instrument panel has a three-layer structure in which a foam having elasticity is disposed between a hard base material and a flexible skin material, and the rear side portion is configured. Moreover, the instrument panel has a one-layer structure in which the front side portion is composed only of a hard base material.

図１０に示すように、前記インストルメントパネル６０は予備成形した基材６２および予備成形した表皮材６４を成形型の第１成形型７８および第２成形型８０に夫々セットしたもとで、成形型を型閉めした際に基材６２および表皮材６４の間に画成される発泡空間７０内で発泡原料を発泡させて、後側部分７４と前側部分７２とが一体的に形成される(例えば、特許文献１参照)。   As shown in FIG. 10, the instrument panel 60 is molded under the condition that a preformed base material 62 and a preformed skin material 64 are set in a first molding die 78 and a second molding die 80, respectively. When the mold is closed, the foaming raw material is foamed in the foaming space 70 defined between the base material 62 and the skin material 64, so that the rear part 74 and the front part 72 are integrally formed ( For example, see Patent Document 1).

特開平９−３８９９９号公報JP-A-9-38999

前記インストルメントパネル６０は、前側部分７２の表面に硬質な基材６２が剥き出しとなっているので、基材６２より柔らかい表皮材６４で表面が構成された後側部分７４と比べ前側部分７２がソフトな質感に欠ける、という問題がある。また、インストルメントパネル６０では、表皮材６４の外縁輪郭部に成形された表皮材シール部６６を、発泡空間７０内で発泡する発泡原料の発泡圧により基材６２へ押し付けて前側部分７２と後側部分７４の境界部７６を封止している。しかしながら表皮材シール部６６と基材６２との間のシールが不充分で、発泡体６８が漏れ出して、境界部７６が波打ったりする等、見栄えが悪化する問題が指摘される。そして、漏出して硬化した発泡体６８を除去するための手間もかかる。   In the instrument panel 60, the hard base material 62 is exposed on the surface of the front side portion 72, so that the front side portion 72 has a surface portion composed of a skin material 64 softer than the base material 62. There is a problem of lack of soft texture. Further, in the instrument panel 60, the skin material seal portion 66 formed on the outer edge contour portion of the skin material 64 is pressed against the base material 62 by the foaming pressure of the foaming material foamed in the foaming space 70, and the front portion 72 and the rear portion 72. The boundary portion 76 of the side portion 74 is sealed. However, the seal between the skin material seal portion 66 and the base material 62 is insufficient, and a problem that the appearance is deteriorated such as the foam 68 leaking out and the boundary portion 76 undulates is pointed out. Further, it takes time and effort to remove the foam 68 that has leaked and hardened.

すなわち本発明は、従来の技術に内在する前記問題に鑑み、これらを好適に解決するべく提案されたものであって、全体としてソフトな質感を有すると共に見栄えがよい車両内装部材を提供する。   That is, the present invention has been proposed in order to solve these problems inherently in the prior art, and provides a vehicle interior member that has a soft texture as a whole and has a good appearance.

前記課題を克服し、所期の目的を達成するため、本願の請求項１に係る車両内装部材は、

More specifically, the foam 34 includes the second design portion 30, the second seal portion 32 supported by the side portion 18 of the recess 16 via the first seal portion 26, and the foam bottom surface 20 a. The enclosed space is filled. As described above, in the instrument panel 10, the second structure portion 42 is configured by the concave portion 16 of the base material 12, the foam 34, and the second design portion 30 covering the front side of the foam 34. This is a design surface of the second structure portion 42.

図３および図４に示すように、第１表皮材２２の第１シール部２６には、底部シール２６ｂの端部から側部シール２６ａにおける途中部位に亘って切欠部３６が設けられている。インストルメントパネル１０では、切欠部３６の第１意匠部２４側に側部シール２６ａと第２シール部３２とが当接する部分が確保されるようになっていると共に、第２シール部３２の少なくとも一部が該切欠部３６を覆うようになっている。切欠部３６は、側部シール２６ａの厚み方向に貫通して設けられ、例えば第１意匠部２４側に頂部を配置した三角形状に形成されている。切欠部３６は、第１シール部２６の端部から、第１意匠部２４に向けて先細りとなるように、第２構造部４２と第１構造部４０との境界部４４に沿う方向に離間して複数設けられている。   As shown in FIG. 3 and FIG. 4, the first seal portion 26 of the first skin material 22 is provided with a notch 36 extending from the end of the bottom seal 26 b to the middle portion of the side seal 26 a. In the instrument panel 10, a portion where the side seal 26 a and the second seal portion 32 abut on the first design portion 24 side of the notch portion 36 is secured, and at least the second seal portion 32 is provided. A part thereof covers the notch 36. The notch 36 is provided penetrating in the thickness direction of the side seal 26a, and is formed in, for example, a triangular shape having a top disposed on the first design portion 24 side. The notch 36 is spaced apart from the end of the first seal portion 26 in a direction along the boundary 44 between the second structure portion 42 and the first structure portion 40 so as to taper toward the first design portion 24. A plurality of them are provided.

次に、実施例のインストルメントパネル１０の製造方法について説明する。基材１２は、一般部１４および凹部１６を一体的に有する所要形状に、ポリエチレンやポリプロピレン等の合成樹脂からインジェクション成形等によって予め成形されている。第１表皮材２２は、基材１２における一般部１４の被覆対象部位形状に合わせた形状で、オレフィン系熱可塑性エラストマー等の合成樹脂からパウダースラッシュ成形や真空成形等によって予め成形されている。第２表皮材２８は、基材１２の凹部１６との間に発泡空間３８を画成する第２意匠部３０および第１シール部２６に当接する第２シール部３２とを一体的に有する所要形状に、オレフィン系熱可塑性エラストマー等の合成樹脂からパウダースラッシュ成形や真空成形等によって予め成形されている。基材１２には、接着剤等によって、一般部１４の表面および凹部１６のシール側面１８ａから発泡体底部２０ａの一部に亘って、第１表皮材２２が装着される。   Next, the manufacturing method of the instrument panel 10 of an Example is demonstrated. The base material 12 is molded in advance from a synthetic resin such as polyethylene or polypropylene into a required shape integrally having the general portion 14 and the concave portion 16 by injection molding or the like. The first skin material 22 has a shape that matches the shape of the portion to be coated of the general portion 14 of the base material 12 and is previously molded from a synthetic resin such as an olefinic thermoplastic elastomer by powder slush molding or vacuum molding. The second skin material 28 is required to integrally include a second design portion 30 that defines a foaming space 38 between the second skin material 28 and the concave portion 16 of the base material 12 and a second seal portion 32 that contacts the first seal portion 26. The shape is previously molded from a synthetic resin such as an olefin-based thermoplastic elastomer by powder slush molding, vacuum molding, or the like. A first skin material 22 is attached to the base material 12 from the surface of the general portion 14 and the seal side surface 18a of the concave portion 16 to a part of the foam bottom portion 20a by an adhesive or the like.

図５に示すように、第１表皮材２２を装着した基材１２および第２表皮材２８を、第１成形型４６および第２成形型４８に夫々セットする。この際、第１表皮材２２を接着した基材１２を、基材１２の裏側が第１成形型４６の成形面に合うように配置し、第２表皮材２８を、第２表皮材２８の表側が第２成形型４８の成形面に合うように配置する。第１成形型４６および第２成形型４８を閉じることで、第２表皮材２８および基材１２の凹部１６の間に発泡体３４分の発泡空間３８が画成される。この際、第２シール部３２の端部は、第１シール部２６の底部シール２６ｂに沿って配置され、第２シール部３２の第１シール部２６側に臨む面は、第１シール部２６の側部シール２６ａにおける底部シール２６ｂとの接合部位から第１意匠部２４との接合部位に沿って配置される。発泡空間３８にポリウレタン等の発泡原料を入れて発泡成形させ、発泡空間３８に発泡体３４が充填された後、第１成形型４６および第２成形型４８を開き成形品を取り出すことで、一体成形されたインストルメントパネル１０が得られる。   As shown in FIG. 5, the base material 12 and the second skin material 28 on which the first skin material 22 is mounted are set in a first molding die 46 and a second molding die 48, respectively. At this time, the base material 12 to which the first skin material 22 is bonded is arranged so that the back side of the base material 12 matches the molding surface of the first molding die 46, and the second skin material 28 is placed on the second skin material 28. The front side is arranged so as to match the molding surface of the second mold 48. By closing the first mold 46 and the second mold 48, a foam space 38 for the foam 34 is defined between the second skin material 28 and the recess 16 of the base 12. At this time, the end of the second seal portion 32 is disposed along the bottom seal 26 b of the first seal portion 26, and the surface of the second seal portion 32 facing the first seal portion 26 side is the first seal portion 26. It arrange | positions along the joining site | part with the 1st design part 24 from the joining site | part with the bottom part seal | sticker 26b in the side part seal | sticker 26a. A foaming raw material such as polyurethane is put into the foaming space 38 and foam-molded. After the foam 34 is filled in the foaming space 38, the first molding die 46 and the second molding die 48 are opened, and the molded product is taken out. A molded instrument panel 10 is obtained.

次に、実施例のインストルメントパネル１０の作用について説明する。基材１２より柔らかい第１表皮材２２および第２表皮材２８で表面が構成されているので、全体としてソフトな質感を有する。また、前述の発泡空間３８での発泡体３４の発泡成形に際し、発泡原料が膨張すると発泡空間３８の周囲には発泡圧が掛かる。この発泡圧により、第２シール部３２は、第１シール部２６の側部シール２６ａへ押し付けられる。基材１２より柔らかい第１シール部２６は、第２シール部３２との形状追従性がよいので、第１シール部２６と第２シール部３２との間のシール性を向上することができ、第１構造部４０と第２構造部４２との境界部４４からの発泡体３４の漏出を防止することができる。従って、車両内装部材は、境界部４４が設定どおりに延在し、見栄えがよい。また、境界部４４から漏出した発泡体３４の除去作業が不要となり製造コストを抑えることができる。更に、第１表皮材２２の一部である第１シール部２６で第２シール部３２を受けるため、部品点数を増やすこともない。   Next, the effect | action of the instrument panel 10 of an Example is demonstrated. Since the surface is composed of the first skin material 22 and the second skin material 28 that are softer than the base material 12, the overall surface has a soft texture. Further, when the foam material is expanded in the foaming space 38 described above, foaming pressure is applied around the foaming space 38 when the foaming raw material expands. Due to this foaming pressure, the second seal portion 32 is pressed against the side seal 26 a of the first seal portion 26. Since the first seal portion 26 softer than the base material 12 has good shape followability with the second seal portion 32, the sealability between the first seal portion 26 and the second seal portion 32 can be improved. Leakage of the foam 34 from the boundary portion 44 between the first structure portion 40 and the second structure portion 42 can be prevented. Therefore, the vehicle interior member has a good appearance because the boundary portion 44 extends as set. Moreover, the removal operation | work of the foam 34 which leaked from the boundary part 44 becomes unnecessary, and can suppress manufacturing cost. Further, since the second seal portion 32 is received by the first seal portion 26 that is a part of the first skin material 22, the number of parts is not increased.

実施例の第２シール部３２は、側部シール２６ａにおける底部シール２６ｂとの接合部位から第１意匠部２４との接合部位に亘って押し付けられると共に、第２シール部３２の端部は、底部シール２６ｂに押し付けられる構成である(図５の矢印参照)。このため、第２シール部３２と、側部シール２６ａとが互いの面で当接する部位に加えて、第２シール部３２の端部と底部シール２６ｂとの当接部位でも第１シール部２６の柔軟性により、第１シール部２６と第２シール部３２との間のシール性を向上することができる。更に、第２シール部３２は第１シール部２６より硬度が硬いため、第２シール部３２に発泡圧が掛かった際に、第２シール部３２が撓みにくく、第２シール部３２を柔らかい第１シール部２６へ適切に押し当てることができ、シール性が高い。   The second seal portion 32 of the embodiment is pressed from the joint portion with the bottom seal 26b to the joint portion with the first design portion 24 in the side seal 26a, and the end portion of the second seal portion 32 is the bottom portion. The structure is pressed against the seal 26b (see the arrow in FIG. 5). Therefore, in addition to the portion where the second seal portion 32 and the side seal 26a contact each other, the first seal portion 26 also at the contact portion between the end portion of the second seal portion 32 and the bottom seal 26b. Due to this flexibility, the sealing performance between the first seal portion 26 and the second seal portion 32 can be improved. Further, since the second seal portion 32 is harder than the first seal portion 26, when the foam pressure is applied to the second seal portion 32, the second seal portion 32 is difficult to bend and the second seal portion 32 is soft. 1 can be properly pressed against the seal portion 26 and has high sealing performance.

第１シール部２６には、底部シール２６ｂの端部から側部シール２６ａの中間部位までに亘って切欠部３６が設けられている。このため、発泡成形に際して発泡空間３８のガスを切欠部３６に逃がすことができ、発泡空間３８のガス溜まりによる発泡体３４の肉欠きを防止して、第２意匠部３０、第２シール部３２および発泡体底面２０ａの間に発泡体３４を均一に充填させることができる。実施例の切欠部３６は、底部シール２６ｂ側から第１意匠部２４側へ向かうにつれて先細りとなるように設けられているため、切欠部３６による第１意匠部２４への影響を抑制するようになっている。   The first seal portion 26 is provided with a notch 36 extending from the end of the bottom seal 26b to the intermediate portion of the side seal 26a. For this reason, the gas in the foaming space 38 can escape to the notch 36 during foam molding, and the second design portion 30 and the second seal portion 32 are prevented from being cut out of the foam 34 due to gas accumulation in the foaming space 38. And the foam 34 can be uniformly filled between the foam bottom surfaces 20a. The cutout portion 36 of the embodiment is provided so as to taper as it goes from the bottom seal 26b side to the first design portion 24 side, so that the influence of the cutout portion 36 on the first design portion 24 is suppressed. It has become.

実施例の第１表皮材２２の表側および第２表皮材２８の表側には、夫々異なるシボ加工がなされていている。このように、実施例のインストルメントパネル１０は、第１表皮材２２および第２表皮材２８が異なる表面外観を有し、全体として基材１２よりソフトな質感を有する。ここで、異なる表面外観とは、色、質感、風合い等の違いをいう。   The surface side of the first skin material 22 and the surface side of the second skin material 28 of the embodiment are respectively subjected to different embossing. As described above, in the instrument panel 10 of the embodiment, the first skin material 22 and the second skin material 28 have different surface appearances and have a softer texture than the base material 12 as a whole. Here, different surface appearances refer to differences in color, texture, texture, and the like.

前述した実施例の構成に限定されず、以下のように変更することも可能である。
(１)実施例では、単層の第１表皮材を使用したが、前記第１表皮材の基材側が弾力性を有する発泡層で構成された多層構造の第１表皮材でもよい。例えば、第１表皮材の表側が発泡層より密度の高い外皮層で構成されて、該外皮層に軟質ウレタンフォーム等からなる発泡層が裏打ちされたものを採用できる。また、第１表皮材における基材側の一部が発泡層で構成されていてもよく、例えば第１シール部における基材側のみが発泡層で構成されていてもよい。このように、第１表皮材の基材側が弾力性を有する発泡層で構成されているので、第１表皮材に覆われる部分の質感を更にソフトにできる。また、第２シール部を受ける第１シール部の弾力性が増すのでシール性をより向上することができる。
(２)実施例では、一般部と、一般部より裏側へ凹むように形成された凹部とを備えた段状に形成された基材を採用するが、凹部と複数の一般部とで複数の段が形成された基材でもよく、凹部が一般部に囲まれた形状の基材でもよい。
(３)実施例では、第１シール部の端部が凹部の底面まで延出されているが、図６に示すように、第１シール部２６が凹部１６の側面２６ａの少なくとも一部を覆っていればよい。
(４)実施例の如く、第２表皮材を第１表皮材より硬く設定するのが好ましいが、第２表皮材が第１表皮材より柔らかくても、同じ硬さであっても、第１シール部が基材より柔らかいので、基材にシールする場合よりシール性を向上することができる。
(５)実施例では、切欠部の形状が三角形であるが、切欠部に発泡空間のガスを逃がすことができ、かつ第２シール部が第１シール部に当接して発泡体をシールできる構成であればよく、例えばスリットでもよい。

The present invention is not limited to the configuration of the embodiment described above, and can be modified as follows.
(1) In the examples, a single-layer first skin material was used, but a first skin material having a multilayer structure in which the base material side of the first skin material is formed of an elastic foam layer may be used. For example, it is possible to adopt a structure in which the front side of the first skin material is constituted by an outer skin layer having a higher density than the foam layer, and the outer skin layer is lined with a foam layer made of soft urethane foam or the like. Moreover, a part of the base material side in the first skin material may be configured by a foam layer, and for example, only the base material side in the first seal portion may be configured by a foam layer. Thus, since the base material side of the 1st skin material is comprised by the foaming layer which has elasticity, the texture of the part covered with the 1st skin material can be further softened. Moreover, since the elasticity of the 1st seal part which receives a 2nd seal part increases, a sealing performance can be improved more.
(2) In the embodiment, a substrate formed in a step shape including a general part and a concave part formed so as to be recessed from the general part to the back side is adopted. The base material in which the step was formed may be sufficient, and the base material of the shape where the recessed part was enclosed by the general part may be sufficient.
(3) In the embodiment, the end portion of the first seal portion extends to the bottom surface of the recess, but the first seal portion 26 covers at least a part of the side surface 26a of the recess 16 as shown in FIG. It only has to be.
(4) Although it is preferable to set the second skin material harder than the first skin material as in the embodiment, the first skin material may be softer than the first skin material or the same hardness. Since the seal part is softer than the base material, the sealing performance can be improved as compared with the case of sealing to the base material.
(5) In the embodiment, the shape of the notch is a triangle, but the configuration allows the gas in the foaming space to escape to the notch, and the second seal to contact the first seal and seal the foam. For example, a slit may be used.
(6) In the embodiment, the first seal portion extending from the side surface of the concave portion to the bottom surface of the concave portion in the base material is provided with the notch portion, but if the notch portion is provided from the end portion of the first seal portion. As shown in FIG. 7, the end of the first seal portion 26 may face the side surface 18 a of the recess 16, and the notch 36 may be provided at the end of the first seal portion 26.
(7) The notch can be omitted.
(8) In the embodiment, the instrument panel divided into two parts having different surface appearances is adopted, but a plurality of parts having different surface appearances may be provided, for example, three parts having different surface appearances are provided. It may be.
(9) In the embodiment, the instrument panel is adopted as the vehicle interior member, but any vehicle interior member in which a plurality of different parts are integrally formed may be used, for example, a floor console, a console lid, a door panel, or the like.
