特許文献１のように、インストルメントパネルに固定的に設けられて車両前後方向と交叉するベース面部（例えばインパネ後面部やセンタークラスタパネルなど）の所定位置に車載機器を配置して固定する構造において、ベース面部から車両前方へ曲折する後曲折部と、後曲折部から車両前方へ延びる中間面部と、中間面部の前端からベース面部と対向しない反ベース面部側へ曲折する前曲折部と、前曲折部から反ベース面部側へ延びる底面部とを有し、ベース面部から車両前方へ凹む凹空間を区画する曲折面部を設け、凹空間に車載機器を配置して固定する場合がある。 In a structure as in Patent Document 1, an in-vehicle device is arranged and fixed at a predetermined position on a base surface portion (for example, an instrument panel rear surface portion, a center cluster panel, etc.) that is fixedly provided on an instrument panel and intersects the vehicle front-rear direction. , A rear bend that bends from the base surface to the front of the vehicle, an intermediate surface that extends from the rear bend to the front of the vehicle, a front bend that bends from the front end of the intermediate surface to the anti-base surface side that does not face the base surface, and a front bend. It has a bottom surface portion extending from the portion to the side opposite to the base surface portion, and a bent surface portion for partitioning a concave space recessed from the base surface portion to the front of the vehicle may be provided, and an in-vehicle device may be arranged and fixed in the concave space.

しかし、インストルメントパネルに上記曲折面部を設ける構造では、曲折面部（特に後曲折部）によってベース面部の面剛性が増大する。このため、車両衝突時等において乗員が前方のインストルメントパネル側（ベース面部や曲折面部）に衝突した際に、インストルメントパネル側から乗員が受ける衝撃を緩和することが好ましい。 However, in the structure in which the instrument panel is provided with the bent surface portion, the surface rigidity of the base surface portion is increased by the bent surface portion (particularly the rear bent surface portion). For this reason, it is preferable to alleviate the impact received by the occupant from the instrument panel side when the occupant collides with the front instrument panel side (base surface portion or bent surface portion) at the time of a vehicle collision or the like.

そこで開示は、車両の衝突時にインストルメントパネル側から乗員が受ける衝撃を緩和することが可能なインストルメントパネル構造の提供を目的とする。 Therefore, the purpose of the disclosure is to provide an instrument panel structure capable of alleviating the impact received by the occupant from the instrument panel side in the event of a vehicle collision.

上記目的を達成すべく、本開示の第１の態様は、車室前方のインストルメントパネルに車両前後方向と交叉するベース面部が固定的に設けられるインストルメントパネル構造であって、曲折面部と底スリットと中間スリットとを備える。 In order to achieve the above object, the first aspect of the present disclosure is an instrument panel structure in which a base surface portion intersecting the vehicle front-rear direction is fixedly provided on an instrument panel in front of the vehicle interior, and the bent surface portion and the bottom thereof are provided. It has a slit and an intermediate slit.

曲折面部は、ベース面部から車両前方へ曲折する後曲折部と、後曲折部から車両前方へ延びる中間面部と、中間面部の前端からベース面部と対向しない反ベース面部側へ曲折する前曲折部と、前曲折部から反ベース面部側へ延びる底面部とを有し、ベース面部から車両前方へ凹む凹空間を区画する。底スリットは、スリット穴形状であり、前曲折部に沿って延びるように底面部に形成される。中間スリットは、スリット穴形状であり、底スリットから前曲折部を横断して中間面部へ延びるように曲折面部に形成される。 The bent surface portion includes a rear bent portion that bends from the base surface portion to the front of the vehicle, an intermediate surface portion that extends from the rear bent portion to the front of the vehicle, and a front bent portion that bends from the front end of the intermediate surface portion to the anti-base surface portion that does not face the base surface portion. It has a bottom surface portion extending from the front bent portion to the side opposite to the base surface portion, and partitions a concave space recessed from the base surface portion to the front of the vehicle. The bottom slit has a slit hole shape and is formed on the bottom surface so as to extend along the front bent portion. The intermediate slit has a slit hole shape, and is formed on the bent surface portion so as to extend from the bottom slit across the front bent portion to the intermediate surface portion.

上記構成では、車両衝突時等に乗員が前方のインストルメントパネル側（ベース面部や曲折面部）に衝突し、曲折面部に前方への荷重が入力すると、底スリット及び中間スリットが拡幅して三次元的に開口する。このため、ベース面部を前方へ大きく移動させることができ、インストルメントパネル側から乗員が受ける衝撃を緩和することができる。 In the above configuration, when the occupant collides with the front instrument panel side (base surface portion or bent surface portion) in the event of a vehicle collision and a forward load is input to the bent surface portion, the bottom slit and the intermediate slit are widened to be three-dimensional. To open. Therefore, the base surface portion can be largely moved forward, and the impact received by the occupant from the instrument panel side can be mitigated.

本開示の第２の態様は、ベース面部を有する組付パネルがインストルメントパネルに固定される第1の態様のインストルメントパネル構造であって、底面部には、インストルメントパネルに固定されるパネル取付部が設けられ、底スリットは、パネル取付部と前曲折部との間を横切るように延びる。 The second aspect of the present disclosure is the instrument panel structure of the first aspect in which the assembly panel having the base surface portion is fixed to the instrument panel, and the bottom surface portion is a panel fixed to the instrument panel. A mounting portion is provided, and the bottom slit extends across between the panel mounting portion and the front bent portion.

上記構成では、底スリットがパネル取付部と前曲折部との間を横切るように延びるので、曲折面部に前方への荷重が入力した際に底スリットが拡幅し易い。このため、インストルメントパネル側から乗員が受ける衝撃をさらに緩和することができる。 In the above configuration, since the bottom slit extends so as to cross between the panel mounting portion and the front bent portion, the bottom slit tends to widen when a forward load is applied to the bent surface portion. Therefore, the impact received by the occupant from the instrument panel side can be further mitigated.

本開示の第３の態様は、車室前方のインストルメントパネルに組付パネルが固定され、組付パネルが車両前後方向と交叉するベース面部を有するインストルメントパネル構造であって、曲折面部と底スリットとを備える。 A third aspect of the present disclosure is an instrument panel structure in which an assembly panel is fixed to an instrument panel in front of the vehicle interior and the assembly panel has a base surface portion that intersects the vehicle front-rear direction, and has a bent surface portion and a bottom. It has a slit.

曲折面部は、ベース面部から車両前方へ曲折する後曲折部と、後曲折部から車両前方へ延びる中間面部と、中間面部の前端からベース面部と対向しない反ベース面部側へ曲折する前曲折部と、前曲折部から反ベース面部側へ延びる底面部とを有し、ベース面部から車両前方へ凹む凹空間を区画する。底スリットは、スリット穴形状であり、前曲折部に沿って延びるように底面部に形成される。底面部には、インストルメントパネルに取付けられるパネル取付部が設けられ、底スリットは、前曲折部とパネル取付部との間を横切るように延びる。 The bent surface portion includes a rear bent portion that bends from the base surface portion to the front of the vehicle, an intermediate surface portion that extends from the rear bent portion to the front of the vehicle, and a front bent portion that bends from the front end of the intermediate surface portion to the anti-base surface portion that does not face the base surface portion. It has a bottom surface portion extending from the front bent portion to the side opposite to the base surface portion, and partitions a concave space recessed from the base surface portion to the front of the vehicle. The bottom slit has a slit hole shape and is formed on the bottom surface so as to extend along the front bent portion. A panel mounting portion to be mounted on the instrument panel is provided on the bottom surface portion, and the bottom slit extends so as to cross between the front bent portion and the panel mounting portion.

上記構成では、車両衝突時等に乗員が前方のインストルメントパネル側（ベース面部や曲折面部）に衝突し、曲折面部に前方への荷重が入力すると、底スリットが拡幅して開口する。また、底スリットがパネル取付部と前曲折部との間を横切るように延びるので、曲折面部に前方への荷重が入力する際に底スリットが拡幅し易い。このため、ベース面部を前方へ大きく移動させることができ、インストルメントパネル側から乗員が受ける衝撃を緩和することができる。 In the above configuration, when the occupant collides with the front instrument panel side (base surface portion or bent surface portion) at the time of a vehicle collision or the like and a forward load is input to the bent surface portion, the bottom slit widens and opens. Further, since the bottom slit extends so as to cross between the panel mounting portion and the front bent portion, the bottom slit tends to widen when a forward load is input to the bent surface portion. Therefore, the base surface portion can be largely moved forward, and the impact received by the occupant from the instrument panel side can be mitigated.

本開示の第４の態様は、第２又は第３の態様のインストルメントパネル構造であって、底面部は、矩形状の底開口を区画する枠形状である。底スリットは、底面部のうち底開口の開口幅の内側領域に形成され、開口幅の外側に延出しない。 The fourth aspect of the present disclosure is the instrument panel structure of the second or third aspect, and the bottom surface portion has a frame shape for partitioning a rectangular bottom opening. The bottom slit is formed in the inner region of the opening width of the bottom opening in the bottom portion and does not extend to the outside of the opening width.

上記構成では、底スリットが底開口の開口幅の外側に延出しないので、底スリットによる組付パネルの剛性の低下を抑制しつつ、インストルメントパネル側から乗員が受ける衝撃を緩和することができる。 In the above configuration, since the bottom slit does not extend outside the opening width of the bottom opening, it is possible to alleviate the impact received by the occupant from the instrument panel side while suppressing the decrease in the rigidity of the assembled panel due to the bottom slit. ..

本開示の第５の態様は、第４の態様のインストルメントパネル構造であって、底スリットから前曲折部までの距離は、底スリットから底開口の開口縁部までの距離よりも短い。 A fifth aspect of the present disclosure is the instrument panel structure of the fourth aspect, in which the distance from the bottom slit to the front bend is shorter than the distance from the bottom slit to the opening edge of the bottom opening.

上記構成では、底スリットから前曲折部までの距離が底開口の開口縁部までの距離よりも短く、底スリットの位置が開口縁部よりも前曲折部に近い（前曲折部側に偏在している）ので、底スリットの位置が開口縁部側に偏在している場合に比べて、ベース面部に前方への荷重が入力した際に底スリットが拡幅し易い。このため、インストルメントパネル側から乗員が受ける衝撃をさらに緩和することができる。 In the above configuration, the distance from the bottom slit to the front bent portion is shorter than the distance to the opening edge of the bottom opening, and the position of the bottom slit is closer to the front bent portion than the opening edge (unevenly distributed on the front bent portion side). Therefore, the bottom slit is more likely to widen when a forward load is applied to the base surface portion, as compared with the case where the positions of the bottom slits are unevenly distributed on the opening edge side. Therefore, the impact received by the occupant from the instrument panel side can be further mitigated.

本開示によれば、車両の衝突時にインストルメントパネル側から乗員が受ける衝撃を緩和することができる。 According to the present disclosure, it is possible to mitigate the impact received by the occupant from the instrument panel side in the event of a vehicle collision.

Further, in the following description, the front-rear direction means the front-rear direction of the vehicle, and the left-right direction means the left-right direction in a state of facing the front of the vehicle.

インストルメントパネル１は、車両の車室２の前方に配置され車体側に固定されて車幅方向に延びる樹脂製のパネルであり、図１に示すように、上下方向と交叉するインパネ上面部３と、インパネ上面部３の後端縁から下方へ延びるインパネ後面部４とを有する。インパネ後面部４の車幅方向中央の上部には、オーディオ機器等の車載機器５（図４参照）が配置されるインパネ中央開口（図示省略）が形成される。インパネ後面部４には、インパネ中央開口を含む領域を後方から覆うように、ベゼル（センタークラスタベゼル）６が取り付けられる。 The instrument panel 1 is a resin panel that is arranged in front of the passenger compartment 2 of the vehicle, is fixed to the vehicle body side, and extends in the vehicle width direction. And an instrument panel rear surface portion 4 extending downward from the rear end edge of the instrument panel upper surface portion 3. An instrument panel central opening (not shown) in which an in-vehicle device 5 (see FIG. 4) such as an audio device is arranged is formed in the upper part of the instrument panel rear surface portion 4 in the center in the vehicle width direction. A bezel (center cluster bezel) 6 is attached to the instrument panel rear surface portion 4 so as to cover the area including the instrument panel central opening from the rear.

ベゼル６は、インパネ後面部４に対して後方から取付けられる樹脂製の化粧パネルであり、図２〜図５に示すように、前後方向と交叉するベース面部１０と、ベース面部１０から前方へ凹んで矩形状の凹空間１１を区画する曲折面部１２とを一体的に有する。ベース面部１０はインストルメントパネル１に固定的に設けられ、ベース面部１０を有するベゼル６は組付パネルを構成する。なお、一体的とは、一体成形されていることに加え、別体で成形されたものを固定することにより一体化することを含む。また、以下の説明において、ベゼル６に関する方向は、特に説明のない限り、ベゼル６をインパネ後面部４に取り付けたベゼル取付状態における方向を示す。 The bezel 6 is a resin decorative panel attached to the instrument panel rear surface portion 4 from the rear, and as shown in FIGS. 2 to 5, the base surface portion 10 intersecting the front-rear direction and the base surface portion 10 are recessed forward. It integrally has a bent surface portion 12 for partitioning the rectangular concave space 11. The base surface portion 10 is fixedly provided on the instrument panel 1, and the bezel 6 having the base surface portion 10 constitutes an assembly panel. In addition to being integrally molded, the term "integral" includes fixing a separately molded product to be integrated. Further, in the following description, the direction with respect to the bezel 6 indicates a direction in a bezel-mounted state in which the bezel 6 is mounted on the instrument panel rear surface portion 4 unless otherwise specified.

曲折面部１２は、ベース面部１０から前方へ凹む階段形状であり、ベース面部１０から前方へ曲折する後曲折部１３と、後曲折部１３から前方へ延びる中間面部１４と、中間面部１４の前端からベース面部１０と対向しない反ベース面部側へ曲折する前曲折部１５と、前曲折部１５から反ベース面部側へ延びる底面部１６とを有する。 The bent surface portion 12 has a staircase shape that is recessed forward from the base surface portion 10, and has a rear bent portion 13 that bends forward from the base surface portion 10, an intermediate surface portion 14 that extends forward from the rear bent portion 13, and the front end of the intermediate surface portion 14. It has a front bent portion 15 that bends toward the anti-base surface portion that does not face the base surface portion 10, and a bottom surface portion 16 that extends from the front bent portion 15 toward the anti-base surface portion side.

底面部１６は、矩形状の底開口１７を区画する枠形状である。底面部１６には複数のボルト挿通孔１９が形成され、ボルト挿通孔１９を挿通するボルト（図示省略）によって車載部品５がベゼル６に締結固定される。底開口１７は、ベゼル６に固定された車載機器５の前面を前方へ露出させる。 The bottom surface portion 16 has a frame shape for partitioning the rectangular bottom opening 17. A plurality of bolt insertion holes 19 are formed in the bottom surface portion 16, and the in-vehicle component 5 is fastened and fixed to the bezel 6 by bolts (not shown) through which the bolt insertion holes 19 are inserted. The bottom opening 17 exposes the front surface of the vehicle-mounted device 5 fixed to the bezel 6 to the front.

底面部１６の前面には、複数（本実施形態では、底開口１７の上方に３箇所、下方に２箇所）のクリップ（パネル取付部）２０が突設される。各クリップ２０をインパネ後面部４に形成された矩形状のクリップ係止孔１８に後方から挿入して係止することにより、底面部１６がインパネ後面部４に取付けられる。また、ベゼル６には、曲折面部１２以外の位置でベゼル６をインパネ後面部４へ取付けるための他の複数（図３にその一部を示す）のクリップ２１が設けられている。 A plurality of clips (panel mounting portions) 20 (in this embodiment, three locations above the bottom opening 17 and two locations below) are projected from the front surface of the bottom surface portion 16. The bottom surface 16 is attached to the instrument panel rear surface 4 by inserting and locking each clip 20 into the rectangular clip locking hole 18 formed in the instrument panel rear surface 4 from the rear. Further, the bezel 6 is provided with a plurality of clips 21 (part of which is shown in FIG. 3) for attaching the bezel 6 to the instrument panel rear surface portion 4 at a position other than the bent surface portion 12.

曲折面部１２には、１本の底スリット２２と、左右に離間した２本の中間スリット２７とが形成されている。底スリット２２及び中間スリット２７は、曲折面部１２を貫通するスリット穴形状である。底スリット２２と中間スリット２７とは互いに連通し、底スリット２２及び中間スリット２７の拡幅により両者が一体となって三次元的に開口し得る。なお、底スリット２２及び中間スリット２７の数は上記に限定されず、任意に設定可能である。 The bent surface portion 12 is formed with one bottom slit 22 and two intermediate slits 27 separated to the left and right. The bottom slit 22 and the intermediate slit 27 have a slit hole shape penetrating the bent surface portion 12. The bottom slit 22 and the intermediate slit 27 communicate with each other, and the widening of the bottom slit 22 and the intermediate slit 27 allows both to be integrally opened three-dimensionally. The number of bottom slits 22 and intermediate slits 27 is not limited to the above, and can be set arbitrarily.

底スリット２２は、底開口１７の下方の底面部１６で、クリップ２０と前曲折部１５との間を横切るように、前曲折部１５に沿って車幅方向に直線状に延びる。中間スリット２７は、底スリット２２から前曲折部１５を横断し、後方の後曲折部１３に向かって中間面部１４を直線状に延びる。 The bottom slit 22 is a bottom surface portion 16 below the bottom opening 17, and extends linearly in the vehicle width direction along the front bent portion 15 so as to cross between the clip 20 and the front bent portion 15. The intermediate slit 27 crosses the front bent portion 15 from the bottom slit 22 and extends linearly along the intermediate surface portion 14 toward the rear bent portion 13.

底スリット２２は、底面部１６のうち底開口１７の開口幅Ｄの内側領域２３に形成され、開口幅Ｄの外側に延出しない。底開口１７の開口幅Ｄの内側領域２３とは、底開口１７の左右の開口縁部２４を下方へ延長した左右の境界線２５の間の領域であり、底スリット２２は、左右の境界線２５を超えて左右に延出しない（図３参照）。また、底スリット２２は、前曲折部１５側に偏在し、底スリット２２から前曲折部１５までの距離Ｌ１は、底スリット２２から底開口１７の下方の開口縁部２６までの距離Ｌ２よりも短い。 The bottom slit 22 is formed in the inner region 23 of the opening width D of the bottom opening 17 in the bottom surface portion 16 and does not extend to the outside of the opening width D. The inner region 23 of the opening width D of the bottom opening 17 is a region between the left and right boundary lines 25 extending the left and right opening edge portions 24 of the bottom opening 17 downward, and the bottom slit 22 is the left and right boundary lines. It does not extend beyond 25 to the left or right (see FIG. 3). Further, the bottom slits 22 are unevenly distributed on the front bent portion 15 side, and the distance L1 from the bottom slit 22 to the front bent portion 15 is larger than the distance L2 from the bottom slit 22 to the opening edge 26 below the bottom opening 17. short.

本実施形態によれば、車両衝突時等に乗員が前方のインストルメントパネル１側（ベース面部１０や曲折面部１２）に衝突し、曲折面部１２に前方への荷重が入力すると、底スリット２２及び中間スリット２７が拡幅して三次元的に開口する。このため、ベース面部１０を前方へ大きく移動させることができ、インストルメントパネル１側から乗員が受ける衝撃を緩和することができる。 According to the present embodiment, when a occupant collides with the front instrument panel 1 side (base surface portion 10 or bent surface portion 12) at the time of a vehicle collision or the like and a forward load is input to the bent surface portion 12, the bottom slit 22 and the bent surface portion 12 and The intermediate slit 27 widens and opens three-dimensionally. Therefore, the base surface portion 10 can be largely moved forward, and the impact received by the occupant from the instrument panel 1 side can be alleviated.

底スリット２２がクリップ２０と前曲折部１５との間を横切るように延びるので、曲折面部１２に前方への荷重が入力した際に底スリット２２が拡幅し易い。このため、インストルメントパネル１側から乗員が受ける衝撃をさらに緩和することができる。 Since the bottom slit 22 extends so as to cross between the clip 20 and the front bent portion 15, the bottom slit 22 tends to widen when a forward load is applied to the bent surface portion 12. Therefore, the impact received by the occupant from the instrument panel 1 side can be further mitigated.

底スリット２２が底開口１７の開口幅Ｄの外側に延出しないので、底スリット２２によるベゼル６の剛性の低下を抑制しつつ、インストルメントパネル１側から乗員が受ける衝撃を緩和することができる。 Since the bottom slit 22 does not extend to the outside of the opening width D of the bottom opening 17, it is possible to alleviate the impact received by the occupant from the instrument panel 1 side while suppressing the decrease in the rigidity of the bezel 6 due to the bottom slit 22. ..

また、底スリット２２から前曲折部１５までの距離Ｌ１が底開口１７の開口縁部２６までの距離Ｌ２よりも短く、底スリット２２の位置が開口縁部２６よりも前曲折部１５に近い（前曲折部１５側に偏在している）ので、底スリット２２の位置が開口縁部２６側に偏在している場合に比べて、ベース面部１０に前方への荷重が入力した際に底スリット２２が拡幅し易い。このため、インストルメントパネル１側から乗員が受ける衝撃をさらに緩和することができる。 Further, the distance L1 from the bottom slit 22 to the front bent portion 15 is shorter than the distance L2 to the opening edge portion 26 of the bottom opening 17, and the position of the bottom slit 22 is closer to the front bent portion 15 than the opening edge portion 26 ( Since it is unevenly distributed on the front bent portion 15 side), the bottom slit 22 is unevenly distributed on the opening edge portion 26 side as compared with the case where the bottom slit 22 is unevenly distributed on the opening edge portion 26 side when a forward load is input to the base surface portion 10. Is easy to widen. Therefore, the impact received by the occupant from the instrument panel 1 side can be further mitigated.

例えば、上記実施形態では、ベゼル６をインストルメントパネル１に固定し、ベゼル６にベース面部１０及び曲折面部１２を形成する例を説明したが、インストルメントパネル１にベース面部１０及び曲折面部１２を形成してもよい。 For example, in the above embodiment, the bezel 6 is fixed to the instrument panel 1 and the base surface portion 10 and the bent surface portion 12 are formed on the bezel 6. However, the base surface portion 10 and the bent surface portion 12 are attached to the instrument panel 1. It may be formed.

また、上記実施形態では、底面部１６に底開口１７を形成し、底開口１７の下方の底面部１６に底スリット２２を形成する例を説明したが、底開口１７の下方以外の底面部１６に底スリット２２を形成してもよく、また底面部１６に底開口１７を形成せずに底スリット２２を形成してもよい。 Further, in the above embodiment, an example in which the bottom opening 17 is formed in the bottom surface 16 and the bottom slit 22 is formed in the bottom surface 16 below the bottom opening 17, but the bottom surface 16 other than below the bottom opening 17 has been described. The bottom slit 22 may be formed in the bottom slit 22 or the bottom slit 22 may be formed in the bottom surface portion 16 without forming the bottom opening 17.
