Description

車両用の内装パネル及び車両用の内装パネルの製造方法Interior panel for vehicle and method for manufacturing interior panel for vehicle
　本発明は、インストルメントパネル等の車両用の内装パネル及びその製造方法に関する。 The present invention relates to an interior panel for a vehicle such as an instrument panel and a manufacturing method thereof.
　自動車の車室内にはインストルメントパネルやドアトリム等の内装パネルが設けられている。例えば特許文献１には、こうした内装パネル及びその製造方法が開示されている。 Interior panels such as instrument panels and door trims are installed in the car interior. For example, Patent Document 1 discloses such an interior panel and a manufacturing method thereof.
　従来の内装パネルは、所定の形状に成形された基材と、この基材の表面に貼着された表皮部材とからなっている。 A conventional interior panel is composed of a base material molded into a predetermined shape and a skin member adhered to the surface of the base material.
　基材は、例えばポリプロピレン樹脂によって形成されている。表皮部材は、例えばポリ塩化ビニル樹脂によって形成されている。 The base material is made of, for example, polypropylene resin. The skin member is made of, for example, polyvinyl chloride resin.
　こうした内装パネルを製造するに際しては、まず、射出成形によって上記基材が形成される。そして、上記表皮部材の素材である原反シートが加熱されて軟化され、基材の表面に対して貼着される。原反シートには全体が均一な厚みを有するものが用いられる。 When manufacturing such an interior panel, first, the base material is formed by injection molding. And the raw fabric sheet | seat which is the raw material of the said skin member is heated and softened, and is affixed with respect to the surface of a base material. A raw sheet having a uniform thickness as a whole is used.
特開平１０―１５６８６６号公報JP-A-10-156866
　上述した内装パネル及びその製造方法においては、以下の問題が生じるおそれがある。例えば図１９に示すように、屈曲部１０４を備えたメータフード１０２を有するインストルメントパネルを製造する場合に、基材１１０の表面に対して表皮部材１２０が貼着される。貼着される表皮部材１２０は、屈曲部１０４において他の部位よりも引き伸ばされる。これにより、メータフード１０２の屈曲部１０４において表皮部材１２０のクッション性が損なわれる。そのため、乗員が当該屈曲部１０４を押した際に屈曲部１０４は他の部位に比較して早く圧縮の限界に到達し、触感が損なわれる。 The following problems may occur in the interior panel and the manufacturing method thereof described above. For example, as shown in FIG. 19, when manufacturing an instrument panel having a meter hood 102 having a bent portion 104, a skin member 120 is attached to the surface of a base material 110. The attached skin member 120 is stretched at the bent portion 104 more than other portions. Thereby, the cushioning property of the skin member 120 is impaired at the bent portion 104 of the meter hood 102. Therefore, when the occupant pushes the bent portion 104, the bent portion 104 reaches the compression limit earlier than other portions, and the tactile sensation is impaired.
　これに対して、厚い表皮部材を採用することが考えられる。しかしながら、この場合には、乗員がほとんど触らない部位まで表皮部材が必要以上に厚くされるため、内装パネルの重量が増加するおそれがある。 In contrast, it is conceivable to use a thick skin member. However, in this case, since the skin member is thickened more than necessary to the part that the occupant hardly touches, the weight of the interior panel may increase.
　本発明の目的は、内装パネルにおける触感を好適に向上させつつ、内装パネルの重量の増加を抑制することのできる車両用の内装パネルを提供することにある。また、触感が向上した内装パネルを容易に製造することのできる車両用の内装パネルの製造方法を提供することにある。 An object of the present invention is to provide an interior panel for a vehicle that can suppress an increase in the weight of the interior panel while suitably improving the feel of the interior panel. Moreover, it is providing the manufacturing method of the interior panel for vehicles which can manufacture easily the interior panel which improved the tactile sense.
　上記目的を達成するため、本発明に従う車両用の内装パネルは、基材と、積層された表皮層及びクッション層を有するとともに前記表皮層を外側にして前記基材の表面に貼着される表皮部材とを備える。また、前記基材と前記表皮部材との間の一部にはクッション層を有する中間部材が介在されている。 In order to achieve the above object, an interior panel for a vehicle according to the present invention has a base material, a laminated skin layer and a cushion layer, and is attached to the surface of the base material with the skin layer on the outside. A member. An intermediate member having a cushion layer is interposed between a part of the base material and the skin member.
　同構成によれば、内装パネルにおいて中間部材が介在されている部分におけるクッション層が厚くなる。このため、内装パネルのクッション層を部分的に厚くすることができる。従って、内装パネルにおける特定の部分の触感を好適に向上させつつ、内装パネルの重量の増加を抑制することができる。 According to this configuration, the cushion layer at the portion where the intermediate member is interposed in the interior panel becomes thick. For this reason, the cushion layer of the interior panel can be partially thickened. Therefore, an increase in the weight of the interior panel can be suppressed while suitably improving the tactile sensation of a specific portion of the interior panel.
　前記基材の表面には少なくとも前記中間部材の端部を収納する凹部が形成されていることが好ましい。 It is preferable that a recess for accommodating at least the end of the intermediate member is formed on the surface of the base material.
　この場合、基材の表面に形成された凹部に中間部材の端部が入り込むため、中間部材の端部において表皮部材の表面に形成される段差を小さくできる。従って、内装パネルの意匠性や触感が損なわれることを好適に抑制することができる。 In this case, since the end of the intermediate member enters the recess formed on the surface of the base material, the step formed on the surface of the skin member at the end of the intermediate member can be reduced. Therefore, it can suppress suitably that the designability and tactile sense of an interior panel are impaired.
　また、前記基材の表面と前記中間部材の表面とが面一になるように前記凹部に前記中間部材が収納されていることが好ましい。 Further, it is preferable that the intermediate member is housed in the recess so that the surface of the base material and the surface of the intermediate member are flush with each other.
　この場合、凹部によって、基材と中間部材とが面一にされるため、中間部材の端部によって表皮部材の表面に段差が形成されない。従って、内装パネルの意匠性や触感が損なわれることを回避することができる。 In this case, since the base material and the intermediate member are flush with each other by the recess, no step is formed on the surface of the skin member by the end of the intermediate member. Therefore, it can avoid that the designability and tactile sense of an interior panel are impaired.
　前記中間部材の前記凹部に収納される端部は尖形の断面形状を有し、前記端部において前記中間部材の裏面は同端部の先端に近づくほど前記中間部材の表面に徐々に近づくように同表面に対して傾斜しており、前記基材は前記凹部を形成した第１部位と、前記凹部を形成していない第２部位とを備え、前記第２部位の表面と前記凹部の底面との間に傾斜面が形成され、その傾斜面によって前記第２部位の表面が前記凹部の底面に接続されていることが好ましい。 An end portion of the intermediate member housed in the recess has a pointed cross-sectional shape, and the back surface of the intermediate member at the end portion gradually approaches the surface of the intermediate member as it approaches the tip of the end portion. And the base member includes a first part in which the concave part is formed and a second part in which the concave part is not formed, and the surface of the second part and the bottom surface of the concave part. It is preferable that an inclined surface is formed between and the surface of the second part is connected to the bottom surface of the recess by the inclined surface.
　また、前記基材は前記凹部を形成した第１部位と、前記凹部を形成していない第２部位とを備え、前記基材には前記第２部位と前記凹部との境界において段差部が形成され、前記基材における前記第１部位の厚さは前記段差部から離間するほど増大していることが好ましい。 Further, the base material includes a first part in which the concave part is formed and a second part in which the concave part is not formed, and a stepped part is formed in the base material at a boundary between the second part and the concave part. In addition, it is preferable that the thickness of the first portion of the base material increases as the distance from the stepped portion increases.
　例えば基材の表面において中間部材が設けられている部位の全体にわたって凹部が形成され、基材における凹部の位置には一律に薄くされた薄肉部が形成されることが考えられる。しかしながらこの場合には、薄肉部の厚さによっては基材の剛性が不足するおそれがある。 For example, it is conceivable that a concave portion is formed over the entire portion where the intermediate member is provided on the surface of the base material, and a thin portion that is uniformly thinned is formed at the position of the concave portion in the base material. However, in this case, the rigidity of the substrate may be insufficient depending on the thickness of the thin portion.
　この点、上記のように、基材における凹部が形成されている第１部位の厚さが段差部から離間するほど増大していれば、基材の表面において中間部材が設けられている部位の全体に一律に薄くされる薄肉部を有する構成に比べて、薄肉部を少なくできる。従って、内装パネルの意匠性や触感が損なわれることを好適に抑制することができるとともに、基材の剛性が低下することを好適に抑制することができる。 In this regard, as described above, if the thickness of the first portion where the concave portion is formed in the base material increases as the distance from the step portion increases, the portion of the base member where the intermediate member is provided Compared to a configuration having a thin portion that is uniformly thinned as a whole, the thin portion can be reduced. Therefore, it can suppress suitably that the designability and tactile sense of an interior panel are impaired, and it can suppress suitably that the rigidity of a base material falls.
　前記内装パネルは屈曲部を備え、前記中間部材は少なくとも当該内装パネルの屈曲部に設けられていることが好ましい。 It is preferable that the interior panel includes a bent portion, and the intermediate member is provided at least in the bent portion of the interior panel.
　この場合、少なくとも内装パネルの屈曲部のクッション層を厚くすることができ、その触感を好適に向上させることができる。 In this case, at least the cushion layer of the bent portion of the interior panel can be thickened, and the tactile sensation can be suitably improved.
　また、前記内装パネルは、車両用シートに対向するとともに前記中間部材を備えた部分を有することが好ましい。 Moreover, it is preferable that the interior panel has a portion facing the vehicle seat and provided with the intermediate member.
　この場合、内装パネルにおいて車両用シートに対向した部分に中間部材が設けられるため、乗員が触りやすい部分が厚くされ、当該部分の触感を好適に向上させることができる。一方、内装パネルにおいて乗員が触りにくい部分は厚くされない。従って、内装パネルにおいて乗員が触れやすい部分の触感を好適に向上させつつ、内装パネルの重量の増加を抑制することができる。 In this case, since the intermediate member is provided at the portion of the interior panel that faces the vehicle seat, the portion that is easily touched by the occupant is thickened, and the tactile sensation of the portion can be improved suitably. On the other hand, the portion of the interior panel that is difficult for an occupant to touch is not thickened. Therefore, it is possible to suppress an increase in the weight of the interior panel while suitably improving the tactile sensation of the portion that is easily touched by the occupant in the interior panel.
　また、前記中間部材は前記表皮部材と同一の材料からなることが好ましい。 The intermediate member is preferably made of the same material as the skin member.
　この場合、中間部材が表皮部材と同一の材料からなるため、中間部材が表皮部材とは別の材料からなる構成に比べて、必要な素材の種類が少なくて済み、内装パネルを簡易な構成で形成することができる。 In this case, since the intermediate member is made of the same material as the skin member, the number of types of necessary materials can be reduced compared to a configuration in which the intermediate member is made of a material different from that of the skin member, and the interior panel has a simple configuration. Can be formed.
　また、前記基材の表面において前記中間部材が介在される部分は残りの部分に比べて大きな摩擦係数を有することが好ましい。 Further, it is preferable that the portion where the intermediate member is interposed on the surface of the base material has a larger coefficient of friction than the remaining portion.
　この場合、内装パネルを製造する際に、基材の表面に載置された中間部材がずれにくくなり、中間部材の一部が基材の表面から浮くことが抑制される。従って、表皮部材の一部が浮いたり、表皮部材の表面に皺が形成されたりすることを抑制することができる。 In this case, when manufacturing the interior panel, the intermediate member placed on the surface of the base material is less likely to be displaced, and part of the intermediate member is suppressed from floating from the surface of the base material. Therefore, it can suppress that a part of skin member floats or a wrinkle is formed on the surface of a skin member.
　また、前記基材の表面において前記中間部材が介在される部分にはシボ加工が施されていることが好ましい。 Moreover, it is preferable that the surface of the base material is subjected to a graining process on the portion where the intermediate member is interposed.
　上記目的を達成するため、本発明に従う車両用の内装パネルの製造方法は、基材の表面の一部に対してクッション層を有する中間部材を載置する第１の工程と、積層された表皮層及びクッション層を有する表皮部材を前記基材の表面に貼着する第２の工程であって、前記表皮部材は前記表皮層を外側にして前記中間部材を覆うように貼着される前記第２の工程とを備える。 In order to achieve the above object, a method for manufacturing an interior panel for a vehicle according to the present invention includes a first step of placing an intermediate member having a cushion layer on a part of the surface of a substrate, and a laminated skin It is the 2nd process of sticking the skin member which has a layer and a cushion layer on the surface of the above-mentioned substrate, and the above-mentioned skin member is stuck so that the above-mentioned skin layer may be outside and the above-mentioned intermediate member may be covered 2 steps.
　同方法によれば、基材の表面に対して表皮部材を貼着する工程に先立ち、基材の表面の一部に対してクッション層を有する中間部材を載置することで、クッション層が部分的に厚くされた内装パネルが形成される。従って、クッション層が好適に厚くされてその触感が向上した内装パネルを容易に製造することができる。 According to the method, prior to the step of attaching the skin member to the surface of the base material, the cushion member is partially formed by placing the intermediate member having the cushion layer on a part of the surface of the base material. A thickened interior panel is formed. Therefore, it is possible to easily manufacture an interior panel in which the cushion layer is suitably thickened and the tactile sensation is improved.

　次に、メータフード２を有するインストルメントパネル１の製造方法について説明する。図４（ａ）～（ｃ）に、インストルメントパネル１の各製造工程を模式的に示す。従って、図４において基材１０、中間部材３０、表皮部材２０の形状は説明のために模式的に示されており、図２に示したメータフード２の形状に一致していない。 Next, a method for manufacturing the instrument panel 1 having the meter hood 2 will be described. 4A to 4C schematically show each manufacturing process of the instrument panel 1. FIG. Therefore, in FIG. 4, the shapes of the base material 10, the intermediate member 30, and the skin member 20 are schematically shown for explanation, and do not match the shape of the meter hood 2 shown in FIG.
　まず、射出成形によって周知の態様にて上記基材１０が形成される。 First, the base material 10 is formed in a known manner by injection molding.
　次に、図４（ａ）に示すように、下型５１上に基材１０が載置され、この基材１０の表面においてメータフード２の屈曲部４に対応する位置に中間部材３０が載置される（第１の工程）。 Next, as shown in FIG. 4A, the base material 10 is placed on the lower mold 51, and the intermediate member 30 is placed at a position corresponding to the bent portion 4 of the meter hood 2 on the surface of the base material 10. (First step).
　次に、図４（ｂ）に示すように、下型５１の上方に、直前にヒータによって加熱されて軟化された表皮部材２０（より正確にはその素材である原反シート）がセットされる。ここで、表皮部材２０はその外縁部がクランプ機構５３によって把持されている。全体的に均一な厚みを有する原反シートが用いられる。 Next, as shown in FIG. 4 (b), the skin member 20 (more precisely, the raw material sheet that is the material) that has been heated and softened by the heater just before is set above the lower mold 51. . Here, the outer edge portion of the skin member 20 is held by the clamp mechanism 53. A raw sheet having a uniform thickness as a whole is used.
　次に、図４（ｃ）に示すように、上型５２が降下され、下型５１と上型５２とによって基材１０、中間部材３０、及び表皮部材２０が挟み込まれる。このとき、真空成形によって、表皮部材２０の外縁部が下型５１上に貼着される。下型５１にはその型面の複数箇所に開口する複数の吸引通路５１ａが形成されている。吸引通路５１ａには真空ポンプ５５が接続されている。吸引通路５１ａを介して真空ポンプ５５により表皮部材２０が下型５１の型面に向けて真空吸引されるとともに、下型５１に対して上型５２が押圧されることによって、同表皮部材２０が基材１０（中間部材３０）の表面に貼着される（第２の工程）。基材１０に表皮部材２０が貼着された後に、表皮部材２０の外縁部の余分な部分がトリミングされる。 Next, as shown in FIG. 4C, the upper mold 52 is lowered, and the base material 10, the intermediate member 30, and the skin member 20 are sandwiched between the lower mold 51 and the upper mold 52. At this time, the outer edge part of the skin member 20 is stuck on the lower mold | type 51 by vacuum forming. The lower mold 51 is formed with a plurality of suction passages 51a that open to a plurality of locations on the mold surface. A vacuum pump 55 is connected to the suction passage 51a. The skin member 20 is vacuum-sucked toward the mold surface of the lower mold 51 by the vacuum pump 55 through the suction passage 51a, and the upper mold 52 is pressed against the lower mold 51, whereby the skin member 20 is It sticks on the surface of the base material 10 (intermediate member 30) (2nd process). After the skin member 20 is attached to the base material 10, an excess portion of the outer edge portion of the skin member 20 is trimmed.
　第１実施形態では、第１の工程において載置される中間部材３０は、上記一対の型５１，５２とは別の型を用いて上記第２の工程と同様な真空成形によって形成される。 In the first embodiment, the intermediate member 30 placed in the first process is formed by vacuum forming similar to the second process using a mold different from the pair of molds 51 and 52.
　次に、図５を参照して第１実施形態の作用について説明する。図５のグラフにおいて、実線は、２層のクッション層２２及び３２を備える第１実施形態のメータフード２の屈曲部４に対して押し当て力を印加した場合のストローク量（屈曲部４の変形量）と押し当て力との関係を示している。また、破線は、１層のクッション層を備える屈曲部に対して押し当て力を印加した場合のストローク量（屈曲部の変形量）と押し当て力との関係を示している。 Next, the operation of the first embodiment will be described with reference to FIG. In the graph of FIG. 5, the solid line represents the stroke amount when the pressing force is applied to the bent portion 4 of the meter hood 2 of the first embodiment including the two cushion layers 22 and 32 (deformation of the bent portion 4). The relationship between the amount) and the pushing force is shown. Moreover, the broken line has shown the relationship between the stroke amount (deformation amount of a bending part) at the time of applying pressing force with respect to the bending part provided with one layer of cushion layers, and pressing force.
　図５に実線及び破線にて示すように、押し当て力が０［Ｎ］から徐々に大きくされると、まずはクッション層が圧縮されることによってストローク量が増大する。更に、押し当て力が大きくされると、屈曲部を構成する基材１０が変形することによってストローク量がＬ１、Ｌ２よりも増大する。 As shown by a solid line and a broken line in FIG. 5, when the pressing force is gradually increased from 0 [N], first, the stroke amount is increased by compressing the cushion layer. Further, when the pressing force is increased, the base material 10 constituting the bent portion is deformed, so that the stroke amount is larger than L1 and L2.
　ここで、メータフードの屈曲部が１層のクッション層を有するものでは、第１のストローク量Ｌ１にてクッション層の圧縮の限界に到達する（図５の破線参照）。これに対し、第１実施形態のメータフード２では、第１のストローク量Ｌ１よりも大きい第２のストローク量Ｌ２（Ｌ２＞Ｌ１）でクッション層の圧縮の限界に到達する（図５の実線参照）。従って、メータフード２の屈曲部４におけるクッション層を部分的に厚くすることができる。 Here, when the bent portion of the meter hood has a single cushion layer, the compression limit of the cushion layer is reached at the first stroke amount L1 (see the broken line in FIG. 5). On the other hand, in the meter hood 2 of the first embodiment, the compression limit of the cushion layer is reached with a second stroke amount L2 (L2> L1) larger than the first stroke amount L1 (see the solid line in FIG. 5). ). Accordingly, the cushion layer in the bent portion 4 of the meter hood 2 can be partially thickened.
　以上説明した第１実施形態に係る車両用の内装パネル及び車両用の内装パネルの製造方法によれば、以下に示す効果が得られるようになる。 According to the vehicle interior panel and the vehicle interior panel manufacturing method according to the first embodiment described above, the following effects can be obtained.
　（１）メータフード２は、基材１０と、積層された表皮層２１及びクッション層２２を有するとともに表皮層２１を外側にして基材１０の表面に貼着される表皮部材２０とを備えている。また、メータフード２の屈曲部４には基材１０と表皮部材２０との間に上記表皮部材２０と同一材料の中間部材３０が介在されている。こうした構成によれば、メータフード２において中間部材３０が介在されている屈曲部４のクッション層が厚くなる。このため、メータフード２のクッション層を屈曲部４において部分的に厚くすることができる。従って、メータフード２における屈曲部４の触感を好適に向上させつつ、メータフード２の重量の増加を抑制することができる。 (1) The meter hood 2 includes a base material 10 and a skin member 20 that has a laminated skin layer 21 and a cushion layer 22 and is adhered to the surface of the base material 10 with the skin layer 21 facing outside. Yes. Further, an intermediate member 30 made of the same material as that of the skin member 20 is interposed between the base material 10 and the skin member 20 in the bent portion 4 of the meter hood 2. According to such a configuration, the cushion layer of the bent portion 4 in which the intermediate member 30 is interposed in the meter hood 2 is thickened. For this reason, the cushion layer of the meter hood 2 can be partially thickened at the bent portion 4. Therefore, an increase in the weight of the meter hood 2 can be suppressed while suitably improving the tactile sensation of the bent portion 4 in the meter hood 2.
　（２）中間部材３０が表皮部材２０と同一材料から形成されるため、中間部材が表皮部材とは別の材料から形成される場合に比べて、必要な素材の種類が少なくて済み、メータフード２を簡易な構成で形成できる。 (2) Since the intermediate member 30 is made of the same material as the skin member 20, the number of necessary materials can be reduced compared to the case where the intermediate member is made of a material different from the skin member, and the meter hood 2 can be formed with a simple configuration.
　（３）メータフード２の製造方法は、所定の形状を有する基材１０の表面においてメータフード２の屈曲部４に対応する部分に対してクッション層３２を含む中間部材３０を載置する第１の工程と、基材１０の表面において中間部材３０を含む部分に対して表皮層２１とクッション層２２とを有する表皮部材２０を貼着する第２の工程とを備えている。こうした方法によれば、屈曲部４の厚さが好適に大きくされてその触感が向上したメータフード２を容易に製造することができる。 (3) The manufacturing method of the meter hood 2 is a first method in which the intermediate member 30 including the cushion layer 32 is placed on the surface of the base material 10 having a predetermined shape and corresponding to the bent portion 4 of the meter hood 2. And a second step of attaching the skin member 20 having the skin layer 21 and the cushion layer 22 to the portion including the intermediate member 30 on the surface of the base material 10. According to such a method, the meter hood 2 in which the thickness of the bent portion 4 is suitably increased and the tactile sensation is improved can be easily manufactured.
　＜第２実施形態＞
　以下、図６～図８を参照して、本発明の第２実施形態について説明する。 Second Embodiment
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
　図６に示すように、基材４１０と表皮部材４２０との間に中間部材４３０が介在されていると、中間部材４３０の前側の端部４３５において表皮部材４２０の表面に段差４２５が形成される。そのため、こうした段差によってメータフード４０２の意匠性や触感が損なわれるおそれがある。 As shown in FIG. 6, when the intermediate member 430 is interposed between the base material 410 and the skin member 420, a step 425 is formed on the surface of the skin member 420 at the front end 435 of the intermediate member 430. . Therefore, there is a possibility that the design and feel of the meter hood 402 may be impaired by such a step.
　図７及び図８に示すように、第２実施形態において、メータフード５０２の屈曲部５０４において基材５１０と表皮部材５２０との間には中間部材５３０が介在されている。基材５１０の表面において、中間部材５３０の裏面に対向する部位の全体（第１部位）には、凹部５１４が形成されている。基材５１０において中間部材５３０に対向していない部位（第２部位）である基部５１１，５１２の表面と凹部５１４との境界には、段差部５１５が形成されている。このため、基材５１０において凹部５１４が形成されている部位は基部５１１，５１２に比べて薄い薄肉部５１３を構成している。また、基材５１０の表面および中間部材５３０の表面が、基材５１０と中間部材５３０との境界において面一になるように、凹部５１４の深さは中間部材５３０の厚さと同一に設定されている。 7 and 8, in the second embodiment, an intermediate member 530 is interposed between the base material 510 and the skin member 520 in the bent portion 504 of the meter hood 502. A concave portion 514 is formed on the entire surface (first portion) of the surface of the base material 510 facing the back surface of the intermediate member 530. A stepped portion 515 is formed at the boundary between the surface of the base portions 511 and 512 that are portions (second portions) that do not face the intermediate member 530 and the concave portion 514 in the base material 510. For this reason, the site | part in which the recessed part 514 is formed in the base material 510 comprises the thin part 513 thin compared with the base parts 511 and 512. FIG. Further, the depth of the recess 514 is set to be equal to the thickness of the intermediate member 530 so that the surface of the base material 510 and the surface of the intermediate member 530 are flush with each other at the boundary between the base material 510 and the intermediate member 530. Yes.
　次に、第２実施形態の作用について説明する。 Next, the operation of the second embodiment will be described.
　基材５１０の表面に形成された凹部５１４に中間部材５３０の全体が入り込む。そのため、中間部材５３０の端部５３５によって表皮部材５２０の表面に段差が形成されなくなる。 The whole intermediate member 530 enters the recess 514 formed on the surface of the substrate 510. Therefore, no step is formed on the surface of the skin member 520 by the end portion 535 of the intermediate member 530.
　以上説明した第２実施形態に係る車両用の内装パネル及び車両用の内装パネルの製造方法によれば、第１実施形態の効果（１）～（３）に加え、新たに以下に示す効果が得られるようになる。 According to the vehicle interior panel and the vehicle interior panel manufacturing method according to the second embodiment described above, in addition to the effects (1) to (3) of the first embodiment, the following effects are newly provided. It will be obtained.
　（４）基材５１０の表面には中間部材５３０を収納する凹部５１４が形成されており、凹部５１４の深さは中間部材５３０の厚さと同一に設定されている。これにより、中間部材５３０の端部５３５によって表皮部材５２０の表面に段差が形成されなくなり、メータフード５０２の意匠性や触感が損なわれることを回避することができる。 (4) A recess 514 for accommodating the intermediate member 530 is formed on the surface of the base 510, and the depth of the recess 514 is set to be the same as the thickness of the intermediate member 530. Thereby, a step is not formed on the surface of the skin member 520 by the end portion 535 of the intermediate member 530, and it is possible to avoid that the design and feel of the meter hood 502 are impaired.
　＜第３実施形態＞
　以下、図９及び図１０を参照して、本発明の第３実施形態について説明する。 <Third Embodiment>
Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 9 and 10.
　図７に示すように、基材５１０の表面において中間部材５３０が設けられている部位の全体（第１部位）にわたって、中間部材５３０の厚さに等しい深さの凹部５１４が形成される。そのため、基材５１０には、凹部５１４の位置に一律に薄くされた薄肉部５１３が形成される。この場合、薄肉部５１３の厚さによっては基材５１０の剛性が不足するおそれがある。 As shown in FIG. 7, a recess 514 having a depth equal to the thickness of the intermediate member 530 is formed over the entire portion (first portion) where the intermediate member 530 is provided on the surface of the substrate 510. Therefore, the base 510 is formed with a thin portion 513 that is uniformly thinned at the position of the recess 514. In this case, the rigidity of the base material 510 may be insufficient depending on the thickness of the thin portion 513.
　図９及び図１０に示すように、凹部６１４の深さは、中間部材６３０の端部６３５に対応する凹部６１４の最前端において中間部材６３０の厚さと同一に設定される一方、後側へ向けて減少している。従って、基材６１０において凹部６１４が形成されている薄肉部６１３の厚さｔｘは後側へ向けて増大し、すなわち段差部６１５から離間するほど増大する。 As shown in FIGS. 9 and 10, the depth of the recess 614 is set to be the same as the thickness of the intermediate member 630 at the foremost end of the recess 614 corresponding to the end 635 of the intermediate member 630, while facing the rear side. It is decreasing. Therefore, the thickness tx of the thin portion 613 in which the concave portion 614 is formed in the base material 610 increases toward the rear side, that is, increases as the distance from the step portion 615 increases.
　次に、第３実施形態の作用について説明する。 Next, the operation of the third embodiment will be described.
　基材６１０における凹部６１４が形成されている薄肉部６１３の厚さｔｘが段差部６１５から離間するほど増大している。そのため、基材の表面において中間部材が設けられている部位の全体にわたって凹部が形成される構成に比べて、薄肉部６１３を小さくできる。 The thickness tx of the thin part 613 in which the concave part 614 in the base material 610 is formed increases as the distance from the step part 615 increases. Therefore, the thin-walled portion 613 can be made smaller than the configuration in which the concave portion is formed over the entire portion where the intermediate member is provided on the surface of the base material.
　以上説明した第３実施形態に係る車両用の内装パネル及び車両用の内装パネルの製造方法によれば、第１実施形態の効果（１）～（３）、第２実施形態の効果（４）に加え、新たに以下に示す効果が得られる。 According to the vehicle interior panel and the vehicle interior panel manufacturing method according to the third embodiment described above, the effects (1) to (3) of the first embodiment and the effect (4) of the second embodiment. In addition, the following effects can be newly obtained.
　（５）基材６１０における凹部６１４が形成されている薄肉部６１３の厚さｔｘは後側へ向けて増大し、すなわち段差部６１５から離間するほど増大する。こうした構成によれば、薄肉部６１３が小さくて済むため、メータフード６０２の意匠性や触感が損なわれることを好適に抑制することができるとともに、基材６１０の剛性が低下することを好適に抑制することができる。 (5) The thickness tx of the thin portion 613 in which the concave portion 614 is formed in the substrate 610 increases toward the rear side, that is, increases as the distance from the step portion 615 increases. According to such a configuration, since the thin-walled portion 613 can be small, it is possible to suitably suppress the designability and tactile sensation of the meter hood 602 and to appropriately suppress the rigidity of the base material 610 from being lowered. can do.
　＜第４実施形態＞
　以下、図１１～図１３を参照して、本発明の第４実施形態について説明する。 <Fourth embodiment>
The fourth embodiment of the present invention will be described below with reference to FIGS.
　図１１に示すように、基材７１０の段差部７１５の壁面と中間部材７３０の端部７３５の先端７３６とが隣接される構成においては、同壁面の高さと先端７３６の高さとが異なることがある。この場合、表皮部材７２０の表面における上記壁面と上記先端７３６との境界、すなわち同図に示されるＰ位置に触感の差が生じ、メータフード７０２の触感が損なわれるおそれがある。そのため、基材７１０の段差部７１５や中間部材７３０の端部７３５の高さは、緻密に管理されなければならない。 As shown in FIG. 11, in the configuration in which the wall surface of the stepped portion 715 of the base material 710 and the tip 736 of the end 735 of the intermediate member 730 are adjacent to each other, the height of the wall surface and the height of the tip 736 may be different. is there. In this case, a difference in tactile sensation occurs at the boundary between the wall surface and the tip 736 on the surface of the skin member 720, that is, the P position shown in the figure, and the tactile sensation of the meter hood 702 may be impaired. Therefore, the height of the stepped portion 715 of the base material 710 and the end portion 735 of the intermediate member 730 must be managed precisely.
　第４実施形態では、図１２及び図１３に示すように、中間部材８３０の端部８３５は尖形の断面形状を有している。端部８３５において中間部材８３０の裏面は前側ほど、すなわち同端部８３５の先端８３６に近づくほど中間部材８３０の表面に徐々に近づくように同表面に対して傾斜している。 In the fourth embodiment, as shown in FIGS. 12 and 13, the end 835 of the intermediate member 830 has a pointed cross-sectional shape. In the end portion 835, the back surface of the intermediate member 830 is inclined with respect to the front surface, that is, gradually approaches the surface of the intermediate member 830 as it approaches the front end 836 of the end portion 835.
　また、基材８１０は、凹部８１４を形成した第１部位と凹部を形成していない第２部位とを備える。基部８１１（第２部位）の表面と凹部８１４の底面との間には傾斜面が形成され、該傾斜面は基部８１１に対して傾斜している。該傾斜面によって基部８１１の表面は凹部の底面に接続されている。薄肉部８１３の厚さは基部８１１に近づくほど連続的に大きくされている。従って、図１３に示すように、第１部位と第２部位との境界Ｂの近傍において表皮部材８２０の表面は平滑であり、同境界Ｂには段差部が存在しない。 Further, the base material 810 includes a first portion where the recess 814 is formed and a second portion where the recess is not formed. An inclined surface is formed between the surface of the base portion 811 (second portion) and the bottom surface of the concave portion 814, and the inclined surface is inclined with respect to the base portion 811. The surface of the base portion 811 is connected to the bottom surface of the concave portion by the inclined surface. The thickness of the thin portion 813 is continuously increased as it approaches the base portion 811. Therefore, as shown in FIG. 13, the surface of the skin member 820 is smooth in the vicinity of the boundary B between the first part and the second part, and no stepped portion exists on the boundary B.
　以上説明した第４実施形態に係る車両用の内装パネル及び車両用の内装パネルの製造方法によれば、第１実施形態の効果（１）～（３）に加え、新たに以下に示す効果が得られるようになる。 According to the vehicle interior panel and the vehicle interior panel manufacturing method according to the fourth embodiment described above, in addition to the effects (1) to (3) of the first embodiment, the following effects are newly provided. It will be obtained.
　（６）中間部材８３０の凹部８１４に収納される端部８３５は尖形の断面形状を有している。同端部８３５において中間部材８３０の裏面は同端部８３５の先端８３６に近づくほど中間部材８３０の表面に徐々に近づくように同表面に対して傾斜している。また、基材８１０は凹部８１４を形成した第１部位と、凹部を形成していない第２部位（基部８１１）とを備えている。基部８１１の表面と凹部８１４の底面との間には傾斜面が形成され、その傾斜面によって第２部位（基部８１１）の表面と凹部８１４の底面とは、接続されている。こうした構成によれば、中間部材８３０の端部８３５によって表皮部材８２０の表面に段差が形成されなくなる。従って、内装パネルの意匠性や触感が損なわれることを回避することができるとともに、基材８１０や中間部材８３０を容易に製造することができる。 (6) The end 835 housed in the recess 814 of the intermediate member 830 has a pointed cross-sectional shape. In the same end 835, the back surface of the intermediate member 830 is inclined with respect to the same surface so as to gradually approach the surface of the intermediate member 830 as it approaches the tip 836 of the same end 835. In addition, the base material 810 includes a first portion in which the concave portion 814 is formed and a second portion (base portion 811) in which the concave portion is not formed. An inclined surface is formed between the surface of the base portion 811 and the bottom surface of the recess portion 814, and the surface of the second portion (base portion 811) and the bottom surface of the recess portion 814 are connected by the inclined surface. According to such a configuration, no step is formed on the surface of the skin member 820 by the end portion 835 of the intermediate member 830. Therefore, it can avoid that the designability and tactile sense of an interior panel are impaired, and the base material 810 and the intermediate member 830 can be manufactured easily.
　＜第５実施形態＞
　以下、図１４～図１６を参照して、本発明の第５実施形態について説明する。 <Fifth Embodiment>
Hereinafter, a fifth embodiment of the present invention will be described with reference to FIGS.
　メータフードを製造する際に、基材の表面に載置された中間部材が所定の位置からずれることがある。この場合、図１４に示すように、中間部材７３０の一部が基材７１０の表面から浮いた状態で表皮部材７２０が基材７１０及び中間部材７３０に貼着されることで、表皮部材７２０の一部が浮いたり、表皮部材７２０の表面に皺が形成されたりするおそれがある。 When manufacturing the meter hood, the intermediate member placed on the surface of the base material may be displaced from a predetermined position. In this case, as shown in FIG. 14, the skin member 720 is attached to the base material 710 and the intermediate member 730 in a state where a part of the intermediate member 730 is lifted from the surface of the base material 710. There is a risk that a part of the surface floats or a wrinkle is formed on the surface of the skin member 720.
　図１５及び図１６に示すように、第５実施形態の基材９１０の薄肉部９１３の表面にはシボ加工が施されている。また、基部９１１を含む基材９１０の表面のその他の部分にはシボ加工が施されていない。従って、薄肉部９１３の表面は上記その他の部分に比べて摩擦係数が大きくされている。 As shown in FIGS. 15 and 16, the surface of the thin portion 913 of the base material 910 of the fifth embodiment is subjected to a textured process. In addition, the other parts of the surface of the base material 910 including the base 911 are not subjected to the texture processing. Therefore, the surface of the thin portion 913 has a higher coefficient of friction than the other portions.
　次に、第５実施形態の作用について説明する。 Next, the operation of the fifth embodiment will be described.
　基材９１０の薄肉部９１３の表面は基材９１０の表面のその他の部分に比べて大きな面粗度を有し、大きな摩擦係数を有する。そのため、メータフード９０２を製造する際に、基材９１０の表面に載置された中間部材９３０がずれにくくなり、中間部材９３０の一部が基材９１０の表面から浮くことが抑制される。 The surface of the thin portion 913 of the base material 910 has a larger surface roughness than the other portions of the surface of the base material 910, and has a large friction coefficient. Therefore, when the meter hood 902 is manufactured, the intermediate member 930 placed on the surface of the base material 910 is hardly displaced, and a part of the intermediate member 930 is suppressed from floating from the surface of the base material 910.
　また、基材９１０における中間部材９３０が載置されない部分にはシボ加工が施されていないため、基材９１０と表皮部材９２０とが好適に密着され、基材９１０に対して表皮部材９２０が好適に貼着される。 In addition, since the surface of the base material 910 where the intermediate member 930 is not placed is not subjected to the texturing process, the base material 910 and the skin member 920 are preferably in close contact with each other, and the skin member 920 is suitable for the base material 910. Affixed to.
　以上説明した第５実施形態に係る車両用の内装パネル及び車両用の内装パネルの製造方法によれば、第１実施形態の効果（１）～（３）、第２実施形態の効果（４）に加え、新たに以下に示す効果が得られるようになる。 According to the vehicle interior panel and the vehicle interior panel manufacturing method according to the fifth embodiment described above, the effects (1) to (3) of the first embodiment and the effect (4) of the second embodiment. In addition, the following effects can be newly obtained.
　（７）基材９１０の薄肉部９１３の表面にはシボ加工が施されており、同薄肉部９１３の表面は基材９１０の表面のその他の部分に比べて大きな摩擦係数を有する。こうした構成によれば、表皮部材９２０の一部が浮いたり、表皮部材９２０の表面に皺が形成されたりすることを抑制することができるとともに、基材９１０に対して表皮部材９２０を好適に貼着することができる。 (7) The surface of the thin portion 913 of the base material 910 is subjected to graining, and the surface of the thin portion 913 has a larger coefficient of friction than other portions of the surface of the base material 910. According to such a configuration, it is possible to prevent a part of the skin member 920 from floating or formation of wrinkles on the surface of the skin member 920 and to suitably paste the skin member 920 to the base material 910. Can be worn.
