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.
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.

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.

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.
