Description

重ね合わせ内装部品及び重ね合わせ内装部品用のクッション部材Laminated interior parts and cushioning members for laminated interior parts
　本開示は、重ね合わせ内装部品及び重ね合わせ内装部品用のクッション部材に関する。 The present disclosure relates to overlapping interior components and cushioning members for overlapping interior components.
　特許文献１に開示された内装部品は、第１の部材と、第２部材とを備える。第２部材は、第１の部材に向かって突出する複数の突起を有する。各突起は、撓み変形可能であって、先細になっている。 The interior component disclosed in Patent Document 1 includes a first member and a second member. The second member has a plurality of projections projecting toward the first member. Each projection is flexurally deformable and tapered.
　こうした内装部品において、第２の部材が第１の部材に向けて押し込まれると、複数の突起の一部または全体が第１の部材と接触して撓み変形する。この内装部品は、使用者に対して、発泡ウレタンなどの発泡材が埋め込まれた内装部品に似た触感を与える。 In such an interior component, when the second member is pushed toward the first member, part or all of the plurality of projections come into contact with the first member and bend and deform. This interior component gives the user a tactile sensation similar to that of an interior component in which a foam material such as urethane foam is embedded.
国際公開第２０１３／１３２６７７号WO2013/132677
　第２の部材の押し込み量を大きくするために、突起の長さを長くすると、以下の不都合が生じるおそれがある。すなわち、上述したように、先細の突起の長さを長くすると、突起の基端部が太くなる。そのため、第２の部材の表皮部分のうち突起の基端部分とそれ以外の部分とで厚さの差が大きくなるとともに、これに起因して熱収縮量の差が大きくなる。その結果、熱収縮に伴う成形不良、所謂ヒケが第２の部材の表皮部分に発生しやすくなる。これにより、意匠性が損なわれるおそれがある。 If the length of the protrusion is lengthened in order to increase the amount of pushing of the second member, the following problems may occur. That is, as described above, increasing the length of the tapered projection makes the proximal end portion of the projection thicker. Therefore, the difference in thickness between the proximal end portion of the protrusion and the other portion of the outer skin portion of the second member increases, and the difference in the amount of heat shrinkage also increases due to this. As a result, molding defects due to heat shrinkage, so-called sink marks, are likely to occur in the surface of the second member. This may impair the designability.
　これに対して、上記表皮部分を厚くすることでヒケの発生を抑えるようにすると、第２の部材を押し込む際の触感が硬くなるといった別の問題が生じる。
　なお、上述したヒケの問題は、先細の突起に限定されるものではなく、一定の太さの突起であっても、第２の部材の押し込み量を大きくするために突起を長くすることに伴って突起を太くした場合には同様にして生じることとなる。 On the other hand, if the occurrence of sink marks is suppressed by increasing the thickness of the skin portion, there arises another problem that the tactile sensation becomes hard when pushing the second member.
Note that the problem of sink marks described above is not limited to tapered protrusions, and even if the protrusions have a certain thickness, the protrusions may be elongated in order to increase the pushing amount of the second member. If the projection is made thicker, it will occur in the same way.
　また、押し込み量を大きくするために突起を長くすると、第２の部材を押し込む際の反発荷重が小さくなるという背反が生じることとなる。 In addition, if the projection is lengthened in order to increase the amount of pushing, there is a tradeoff that the repulsive load when pushing the second member becomes smaller.
　本開示の一態様に係る重ね合わせ内装部品は、基材と、前記基材を覆う表皮材と、前記基材と前記表皮材との間に設けられるクッション部材と、を備え、前記基材、前記クッション部材、及び前記表皮材が互いに重ね合わせられている。前記クッション部材は、基部であって、前記表皮材に面接触する接触面及び複数の貫通孔を有する、基部と、複数の突起であって、前記各突起が対応する前記貫通孔の縁から前記基材に向かって突出する、突起と、を有し、前記各突起は、仮想軸線に向かって曲がって延びる曲がり部を有し、前記仮想軸線は、前記対応する貫通孔の中心を通るとともに前記接触面に直交する。 A laminated interior component according to an aspect of the present disclosure includes a base material, a skin material covering the base material, and a cushion member provided between the base material and the skin material, the base material, The cushion member and the skin material are superimposed on each other. The cushion member includes a base portion having a contact surface that makes surface contact with the skin material and a plurality of through holes, and a plurality of projections, each of which extends from the edge of the through hole corresponding to each of the projections. and a projection projecting toward the substrate, each projection having a bent portion that bends and extends toward an imaginary axis, the imaginary axis passing through the center of the corresponding through hole and the perpendicular to the contact surface.

　図１に示すように、表皮材１２に対して外力が作用していない状態において、クッション部材１３の基部２０の接触面２１は表皮材１２に接触している。また、この状態において、各突起３０の先端３３は基材１１に接触している。 As shown in FIG. 1 , the contact surface 21 of the base portion 20 of the cushion member 13 is in contact with the skin material 12 when no external force is applied to the skin material 12 . Also, in this state, the tip 33 of each protrusion 30 is in contact with the substrate 11 .
　図１～図３に示すように、突起３０の基端部は、貫通孔２２の内周面よりも貫通孔２２の内側に突出している。
　図１に示すように、突起３０の全体が、当該突起３０が設けられている貫通孔２２を第１仮想軸線Ｖ１に沿って仮想的に延長した領域Ｖ内に位置している。 As shown in FIGS. 1 to 3, the base end portion of the protrusion 30 protrudes inside the through-hole 22 beyond the inner peripheral surface of the through-hole 22 .
As shown in FIG. 1, the entire protrusion 30 is positioned within a region V virtually extending the through hole 22 in which the protrusion 30 is provided along the first imaginary axis V1.
　次に、本実施形態の作用について説明する。
　表皮材１２が基材１１に向けて押し込まれると、クッション部材１３の基部２０から突出する突起３０が基材１１と接触するとともに撓み変形する。このため、使用者に対して、発泡ウレタンなどの発泡材が埋め込まれた内装部品に似た触感を提示することができる。 Next, the operation of this embodiment will be described.
When the skin material 12 is pushed toward the base material 11, the protrusions 30 protruding from the base 20 of the cushion member 13 come into contact with the base material 11 and bend and deform. Therefore, it is possible to provide the user with a tactile sensation similar to that of an interior component in which a foam material such as urethane foam is embedded.
　また、表皮材１２自体に突起３０を設けなくて済むため、突起３０の成形に起因した表皮材１２の成形不良の問題を回避できる。
　また、表皮材１２の厚さを薄くできるため、表皮材１２を押し込む際の触感が硬くなることを抑制できる。 In addition, since it is not necessary to provide the projections 30 on the skin material 12 itself, the problem of defective molding of the skin material 12 due to the molding of the projections 30 can be avoided.
In addition, since the thickness of the skin material 12 can be reduced, it is possible to prevent the skin material 12 from becoming hard to the touch when the skin material 12 is pushed.
　さらに、固定型及び可動型を用いてクッション部材１３を成形する際に、固定型の成形面によって基部２０の接触面２１を成形するとともに、可動型の成形面によって基部２０の上記接触面２１とは反対側の面２４を成形することができる。この場合、固定型の成形面の凸部（図示略）によって突起３０の一部分を成形することができるとともに、基部２０の貫通孔２２を利用して固定型の成形面の凸部からクッション部材１３を引き抜くことができる。このため、突起３０がアンダーカットとなることを回避できる（以上、作用１）。 Furthermore, when molding the cushion member 13 using the fixed mold and the movable mold, the contact surface 21 of the base 20 is molded by the molding surface of the fixed mold, and the contact surface 21 of the base 20 is formed by the molding surface of the movable mold. can mold the opposite face 24 . In this case, a portion of the projection 30 can be molded by the convex portion (not shown) of the molding surface of the stationary mold, and the through hole 22 of the base portion 20 is used to extend the cushion member 13 from the convex portion of the molding surface of the stationary mold. can be pulled out. Therefore, it is possible to prevent the projection 30 from being undercut (the above is effect 1).
　突起３０は、曲がり部３２を有している。このため、図４Ａに示すように、表皮材１２の面方向において突起３０の先端３３に近い位置が押し込まれると、突起３０は潰れるように変形する（以下、潰れ変形）。 The projection 30 has a bent portion 32. Therefore, as shown in FIG. 4A, when a position near the tip 33 of the protrusion 30 is pushed in the surface direction of the skin material 12, the protrusion 30 is deformed so as to be crushed (hereinafter referred to as crushing deformation).
　一方、図４Ｂに示すように、表皮材１２の面方向において突起３０の先端３３から離れた位置が押し込まれると、突起３０が倒れるように変形する（以下、倒れ変形）。
　ここで、潰れ変形には、倒れ変形に比べて大きな荷重が必要となる（以上、作用２）。 On the other hand, as shown in FIG. 4B, when a position apart from the tip 33 of the projection 30 in the surface direction of the surface material 12 is pushed, the projection 30 is deformed so as to collapse (hereinafter referred to as collapse deformation).
Here, the crushing deformation requires a larger load than the falling deformation (above, action 2).
　次に、本実施形態の効果について説明する。
　（１）突起３０は、貫通孔２２の中心を通るとともに接触面２１に直交して延在する第１仮想軸線Ｖ１に向かって曲がって延びる曲がり部３２を有している。 Next, the effects of this embodiment will be described.
(1) The projection 30 has a bent portion 32 that bends and extends toward a first imaginary axis V1 that passes through the center of the through hole 22 and extends orthogonally to the contact surface 21 .
　こうした構成によれば、上記作用１を奏することから、押し込み量の拡大と意匠性の向上との両立を図ることができる。また、上記作用２を奏することができることから、押し込み量の拡大と反発荷重の増大との両立を図ることができる。 According to such a configuration, since the above effect 1 is achieved, it is possible to achieve both an increase in the pushing amount and an improvement in design. In addition, since the effect 2 described above can be achieved, it is possible to achieve both an increase in the pushing amount and an increase in the rebound load.
　（２）突起３０は、縁２３から第１仮想軸線Ｖ１に向かって傾斜して延びる傾斜部３１を有している。曲がり部３２は、傾斜部３１の先端に連なって延びている。
　こうした構成によれば、第１仮想軸線Ｖ１に対する傾斜部３１の傾斜角度、曲がり部３２の曲率、及び第１仮想軸線Ｖ１方向における突起３０の長さを変更することによって、押し込み量及び反発荷重の調整を行うことが可能となる。 (2) The protrusion 30 has an inclined portion 31 extending from the edge 23 at an angle toward the first imaginary axis V1. The bent portion 32 extends continuously from the tip of the inclined portion 31 .
According to such a configuration, by changing the inclination angle of the inclined portion 31 with respect to the first imaginary axis V1, the curvature of the bent portion 32, and the length of the projection 30 in the direction of the first imaginary axis V1, the pushing amount and the rebound load can be changed. Adjustments can be made.
　（３）縁２３は、接触面２１の面方向において湾曲して延びている。突起３０は、縁２３に沿って湾曲している。
　こうした構成によれば、突起３０が貫通孔２２の中心に向けて倒れにくくなる。このため、押し込み量の拡大と反発荷重の増大との両立を一層図ることができる。 (3) The edge 23 extends curvedly in the surface direction of the contact surface 21 . Protrusions 30 are curved along edge 23 .
Such a configuration makes it difficult for the projection 30 to fall toward the center of the through hole 22 . Therefore, it is possible to further achieve both an increase in the pushing amount and an increase in the rebound load.
　（４）貫通孔２２は、平面視扇形状である。縁２３は、扇形の弧の部分である。突起３０は、縁２３に沿って円弧状に湾曲するとともに先細状である。
　こうした構成によれば、貫通孔２２の扇形の中心角を変更することによって、押し込み量及び反発荷重の調整を行うことが可能となる。 (4) The through hole 22 is fan-shaped in plan view. Edge 23 is a segment of a sector arc. The protrusions 30 are arcuately curved and tapered along the edge 23 .
According to such a configuration, by changing the central angle of the sector of the through hole 22, it is possible to adjust the pushing amount and the repulsive load.
　（５）貫通孔２２の扇形の中心角は、９０度である。
　こうした構成によれば、基部２０に対して複数の貫通孔２２を密に配置することが可能となる。 (5) The fan-shaped central angle of the through hole 22 is 90 degrees.
With such a configuration, it is possible to densely arrange the plurality of through holes 22 with respect to the base portion 20 .
　（６）複数の貫通孔２２が、第２仮想軸線Ｖ２に沿って互いに一定の間隔をおいて並んでいる。第２仮想軸線Ｖ２方向において隣り合う突起３０同士は、第２仮想軸線Ｖ２方向において突起３０の先端３３同士が隣り合わないように配置されている。複数の貫通孔２２が、第３仮想軸線Ｖ３に沿って互いに一定の間隔をおいて並んでいる。第３仮想軸線Ｖ３方向において隣り合う突起３０同士は、第３仮想軸線Ｖ３方向において突起３０の先端３３同士が隣り合わないように配置されている。 (6) A plurality of through holes 22 are arranged along the second imaginary axis V2 at regular intervals. Protrusions 30 that are adjacent to each other in the direction of the second imaginary axis V2 are arranged such that tips 33 of the protrusions 30 are not adjacent to each other in the direction of the second imaginary axis V2. A plurality of through holes 22 are arranged along the third imaginary axis V3 at regular intervals. Protrusions 30 that are adjacent to each other in the direction of the third imaginary axis V3 are arranged such that tips 33 of the protrusions 30 are not adjacent to each other in the direction of the third imaginary axis V3.
　上述したように、表皮材１２の面方向において突起３０の先端３３に近い位置ほど反発荷重が大きくなる。このため、複数の貫通孔２２を並べて設ける場合、隣り合う突起３０の先端３３同士が隣り合うように突起３０が配置されると、反発荷重の位置によるばらつきが大きくなる。 As described above, the closer the position is to the tip 33 of the projection 30 in the surface direction of the skin material 12, the greater the repulsive load. Therefore, when a plurality of through-holes 22 are provided side by side, if the protrusions 30 are arranged so that the tips 33 of adjacent protrusions 30 are adjacent to each other, the positional variation of the repulsive load increases.
　この点、上記構成によれば、反発荷重が位置によってばらつくことを、第２仮想軸線Ｖ２方向及び第３仮想軸線Ｖ３方向の双方において低減することができる。すなわち、反発荷重が位置によってばらつくことを、接触面２１の面方向において低減することができる。 In this respect, according to the above configuration, it is possible to reduce the variation in the repulsive load depending on the position in both the second imaginary axis V2 direction and the third imaginary axis V3 direction. That is, it is possible to reduce variation in the repulsive load depending on the position in the surface direction of the contact surface 21 .
