以下、本発明の実施形態を車両用内装材としてルーフトリムを例に採って図面と共に詳述する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings by taking a roof trim as an example of a vehicle interior material.

図１は、サンルーフ仕様の車両に用いられるルーフトリム１を上方から見た略示的外観斜視図で、ルーフトリム１の中央部分には図外のルーフパネルに設定されたサンルーフ部に対応した開窓部２を形成してある。   FIG. 1 is a schematic external perspective view of a roof trim 1 used in a vehicle having a sunroof specification, as viewed from above. An opening corresponding to a sunroof portion set on a roof panel (not shown) is provided at a central portion of the roof trim 1. A window portion 2 is formed.

ルーフトリム１の車幅方向両側部には、トリム前側部ＴＦからトリム後側部ＴＲに亘る所要の長さ領域に、長尺の間接照明装置１０を配設してある。   On both sides of the roof trim 1 in the vehicle width direction, a long indirect lighting device 10 is disposed in a required length region extending from the trim front side portion TF to the trim rear side portion TR.

図１では便宜的に車両左側の間接照明装置１０のみを透視した状態として示している。   In FIG. 1, for convenience, only the indirect lighting device 10 on the left side of the vehicle is shown in a transparent state.

ルーフトリム１は、外周側トリム１Ａと内周側トリム１Ｂの２つのルーフトリム要素（内装材要素）に分割して別体に型成形してある。   The roof trim 1 is divided into two roof trim elements (interior material elements) of an outer peripheral side trim 1A and an inner peripheral side trim 1B, and is molded separately.

図２に示すように、外周側トリム１Ａおよび内周側トリム１Ｂは、例えば、何れも適宜の合成樹脂材からなるトリム芯材３と、該トリム芯材３の室内側の表面を覆う表皮４との積層構成体として成形することができる。   As shown in FIG. 2, the outer peripheral side trim 1 </ b> A and the inner peripheral side trim 1 </ b> B are, for example, a trim core material 3 made of an appropriate synthetic resin material, and a skin 4 that covers the interior surface of the trim core material 3. It can shape | mold as a laminated structure.

表皮４はルーフトリム１の意匠面およびソフトパッド面を構成するもので、適宜の模様や色彩を施した軟質の合成樹脂シートを用いることができる。   The skin 4 constitutes the design surface and the soft pad surface of the roof trim 1, and a soft synthetic resin sheet having an appropriate pattern or color can be used.

外周側トリム１Ａと内周側トリム１Ｂは、外周側トリム１Ａの内周側の端部の背面上方に内周側トリム１Ｂの外周側の端部を所要の間隔をおいてオーバーラップさせて配置してある。   The outer periphery side trim 1A and the inner periphery side trim 1B are arranged so that the outer periphery side end portion of the inner periphery side trim 1B overlaps the back surface of the inner periphery side end portion of the outer periphery side trim 1A at a predetermined interval. It is.

そして、上述のようにルーフトリム１の車幅方向両側部分において、これら外周側トリム１Ａと内周側トリム１Ｂの端部相互間に間接照明装置１０を配置して、外周側トリム１Ａの内周側の端末と内周側トリム１Ｂ面との間の隙間δから点灯光を照射して、該内周側トリム１Ｂの意匠面（表皮４）を間接照明するようにしている。   As described above, the indirect lighting device 10 is arranged between the end portions of the outer peripheral side trim 1A and the inner peripheral side trim 1B at both sides in the vehicle width direction of the roof trim 1, so that the inner periphery of the outer peripheral side trim 1A is arranged. Lighting light is irradiated from a gap δ between the terminal on the side and the inner peripheral trim 1B surface to indirectly illuminate the design surface (skin 4) of the inner peripheral trim 1B.

外周側トリム１Ａには、アシストグリップ２０の配設相当部位に凹陥部５を形成して、該凹陥部５にアシストグリップ２０を格納配置できるようにしている。   The outer trim 1 </ b> A is formed with a recessed portion 5 at a portion corresponding to the placement of the assist grip 20 so that the assist grip 20 can be stored and disposed in the recessed portion 5.

一方、内周側トリム１Ｂの内周側の端部は緩やかに湾曲して立ち上がるフランジ部６を形成して、図外のルーフパネルのサンルーフ部周りに構成されるルーフ強度メンバ２１等のルーフ内面部の構造を隠蔽するようにしている。   On the other hand, the inner peripheral side end of the inner peripheral side trim 1B forms a flange portion 6 that gently rises and rises, and the inner surface of the roof such as the roof strength member 21 formed around the sunroof portion of the roof panel (not shown). The structure of the part is concealed.

ルーフトリム１の車体側への固定は、例えば、外周側トリム１Ａの外周縁をルーフ骨格部材である図外のルーフレールにクリップ等により固定する一方、内周側トリム１Ｂを上述のルーフ強度メンバ２１に図２に示すように止着手段２２により係着して行われる。   For fixing the roof trim 1 to the vehicle body side, for example, the outer peripheral edge of the outer periphery side trim 1A is fixed to a roof rail (not shown) which is a roof frame member with a clip or the like, while the inner periphery side trim 1B is fixed to the roof strength member 21 described above. As shown in FIG. 2, the fixing means 22 is engaged.

このため、内周側トリム１Ｂには、その背面の所要部位に硬質合成樹脂あるいは金属からなるブラケット７を配設して、ルーフ強度メンバ２１とブラケット７に相互に係着する上述の止着手段２２を設けている。   For this reason, the above-mentioned fastening means for arranging the bracket 7 made of hard synthetic resin or metal on a required portion on the back surface of the inner peripheral trim 1B and engaging the roof strength member 21 and the bracket 7 with each other. 22 is provided.

間接照明装置１０は、ハウジング１１と、ハウジング１１に保持された光源１２と、光源１２を覆ってハウジング１１に装着されたレンズ１３と、を備えている。   The indirect lighting device 10 includes a housing 11, a light source 12 held in the housing 11, and a lens 13 that covers the light source 12 and is attached to the housing 11.

ハウジング１１とレンズ１３は何れも適宜の合成樹脂材からなり、レンズ１３を上述の外周側トリム１Ａの内周側の端末と内周側トリム１Ｂの平坦な意匠面（表皮４）との間の隙間δを埋めて配置してある。   Both the housing 11 and the lens 13 are made of an appropriate synthetic resin material, and the lens 13 is disposed between the inner peripheral end of the outer peripheral trim 1A and the flat design surface (skin 4) of the inner peripheral trim 1B. The gap δ is filled.

これにより、光源１２の点灯光を図２の矢印ａに示すように前記隙間δを通してレンズ１３により拡散して照射し、内周側トリム１Ｂの意匠面４を間接照明するようにしている。   As a result, the illumination light of the light source 12 is diffused and irradiated by the lens 13 through the gap δ as shown by the arrow a in FIG. 2, and the design surface 4 of the inner peripheral side trim 1B is indirectly illuminated.

光源１２は、例えば、前述の特許文献１に示された長尺の方形断面に形成した複数のアクリル製の導光体と、その長さ方向端面に配置した平板状のＬＥＤとの組み合わせからなる光源ユニットを用いることができる。   The light source 12 is composed of, for example, a combination of a plurality of acrylic light guides formed in the long rectangular cross section shown in the above-mentioned Patent Document 1 and a flat LED arranged on the end face in the length direction. A light source unit can be used.

そこで、図１，図２に示す実施形態では、光源１２を車両前後方向に複数に分割して配設してあって、ハウジング１１は方形断面の導光体が嵌合可能なコ字型断面としている。   Therefore, in the embodiment shown in FIGS. 1 and 2, the light source 12 is divided into a plurality of parts in the vehicle front-rear direction, and the housing 11 is a U-shaped cross section into which a light guide having a square cross section can be fitted. It is said.

上述の隙間δの下縁を構成する外周側トリム１Ａの内周側の端末部分は、上方に向けて緩やかに湾曲して成形してあり、これに伴ってレンズ１３の下面形状をこのトリム端末部分に面整合する凹凸形状としている。   The terminal portion on the inner peripheral side of the outer peripheral side trim 1A constituting the lower edge of the gap δ described above is formed by gently curving upward, and the lower surface shape of the lens 13 is accordingly changed to the trim terminal. It has a concavo-convex shape that matches the surface.

ここで、本実施形態にあっては、上述の間接照明装置１０は、外周側トリム１Ａの内周側の端部の背面に固設してあって、内周側トリム１Ｂをこの間接照明装置１０を介して連接するようにしている。   Here, in the present embodiment, the indirect lighting device 10 described above is fixed to the back surface of the inner peripheral side end portion of the outer peripheral side trim 1A, and the inner peripheral side trim 1B is fixed to the indirect lighting device. 10 are connected to each other.

本実施形態ではハウジング１１は、その長さ方向（車両前後方向）に所要の間隔をおいて前記外周側トリム１Ａと内周側トリム１Ｂの端部相互間に介在する閉断面形状の複数の座部１４を備えている。そして、この座部１４の下面をレンズ１３の下面と共に外周側トリム１Ａの端部背面に適宜の接着材により接着固定してある。   In the present embodiment, the housing 11 has a plurality of seats having a closed cross-sectional shape interposed between the end portions of the outer periphery side trim 1A and the inner periphery side trim 1B at a predetermined interval in the length direction (vehicle longitudinal direction). Part 14 is provided. The lower surface of the seat portion 14 is bonded and fixed to the rear surface of the end portion of the outer trim 1A together with the lower surface of the lens 13 with an appropriate adhesive.

各座部１４には、その上面側に突出して閉断面が連続するファスナー部１５を形成してあり、該ファスナー部１５を内周側トリム１Ｂおよびブラケット７を貫通して設けた取付孔８に嵌挿することにより、該内周側トリム１Ｂを外周側トリム１Ａに接続するようにしている。   Each seat portion 14 is formed with a fastener portion 15 that protrudes from the upper surface side and has a continuous closed cross section, and the fastener portion 15 is inserted into an attachment hole 8 provided through the inner peripheral trim 1B and the bracket 7. The inner periphery side trim 1B is connected to the outer periphery side trim 1A by being inserted.

また、ファスナー部１５の頂面とルーフ強度メンバ２１に前述と同様の相互に係着する止着手段２２を設けて、間接照明装置１０をこのファスナー部１５を介してルーフ強度メンバ２１に係着固定するようにしている。   Further, the fastening means 22 for engaging with each other is provided on the top surface of the fastener portion 15 and the roof strength member 21 as described above, and the indirect lighting device 10 is attached to the roof strength member 21 via the fastener portion 15. I try to fix it.

以上の構成により本実施形態のルーフトリム１によれば、外周側トリム１Ａの端末と内周側トリム１Ｂとの間の隙間δが、間接照明装置１０の配光用のレンズ１３で埋められて外観が整えられるため、見栄えが良好となって品質感を高めることができる。   According to the roof trim 1 of the present embodiment having the above configuration, the gap δ between the terminal of the outer periphery side trim 1A and the inner periphery side trim 1B is filled with the light distribution lens 13 of the indirect lighting device 10. Since the appearance is adjusted, the appearance is good and the quality can be enhanced.

また、児童等が悪戯して上述の隙間δに指を差し入れることはできないので、外周側トリム１Ａの端末が不当に拡開方向（下側）に変形されることもない。   In addition, since the child or the like cannot play a finger and insert his / her finger into the gap δ, the terminal of the outer trim 1A is not unduly deformed in the expanding direction (lower side).

そして、レンズ１３により前記隙間δを通して間接照明光を車室側に一様に拡散照射できて、間接照明の配光性能を高めることができる。   The indirect illumination light can be uniformly diffused and irradiated to the passenger compartment side through the gap δ by the lens 13, and the light distribution performance of the indirect illumination can be enhanced.

また、本実施形態では間接照明装置１０を外周側トリム１Ａの端部の背面に固設してあって、内周側トリム１Ｂをこの間接照明装置１０を介して連接するようにしている。これにより、専用の連結手段を不要として間接照明装置１０の固定とルーフトリム１のモジュール化とを設計上有利に実施することができる。   Further, in the present embodiment, the indirect lighting device 10 is fixed to the back surface of the end portion of the outer peripheral side trim 1 </ b> A, and the inner peripheral side trim 1 </ b> B is connected via the indirect lighting device 10. Thereby, the fixing of the indirect lighting device 10 and the modularization of the roof trim 1 can be advantageously carried out in terms of design without using a dedicated connecting means.

しかも、間接照明装置１０のレンズ１３を外周側トリム１Ａの端末に固定できるので、該端末の経時的な波打ち変形を抑制することもできて品質感をより一層高めることができる。   In addition, since the lens 13 of the indirect lighting device 10 can be fixed to the terminal of the outer peripheral side trim 1A, the wavy deformation of the terminal over time can be suppressed, and the quality can be further enhanced.

図３は本発明の第２実施形態を示すもので、本実施形態では前述の間接照明装置１０は、外周側トリム１Ａに乗員頭部Ｈの衝突荷重Ｆが作用した場合に、車体パネルであるルーフ強度メンバ２１との間で潰れ変形可能なエネルギー吸収部３０を備えている。   FIG. 3 shows a second embodiment of the present invention. In this embodiment, the indirect lighting device 10 described above is a vehicle body panel when a collision load F of the occupant head H acts on the outer trim 1A. An energy absorbing portion 30 that can be crushed and deformed with the roof strength member 21 is provided.

図３の（Ａ），（Ｂ）に示す例では、間接照明装置１０のハウジング１１に一体成形した座部１４を、下側が開放した開断面に形成している。そして、この開断面の車幅方向両側縁には外周側トリム１Ａの背面に当接する受圧用のフランジ１４ａを設けてある。これにより、フランジ１４ａを介して所定値以上の衝突荷重Ｆが入力すると、座部１４の車幅方向両側の側壁が（Ｂ）図に示すように車体側パネル２１との間で座屈変形するようにしている。   In the example shown in FIGS. 3A and 3B, the seat portion 14 formed integrally with the housing 11 of the indirect lighting device 10 is formed in an open cross section with the lower side open. And the pressure-receiving flange 14a which contact | abuts to the back surface of the outer periphery side trim 1A is provided in the vehicle width direction both-sides edge of this open cross section. Thus, when a collision load F of a predetermined value or more is input via the flange 14a, the side walls on both sides in the vehicle width direction of the seat portion 14 are buckled and deformed between the vehicle body side panel 21 as shown in FIG. I am doing so.

即ち、本実施形態ではハウジング１１の座部１４自体でエネルギー吸収部３０を構成している。   That is, in this embodiment, the energy absorbing portion 30 is configured by the seat portion 14 itself of the housing 11.

また、図示する例では、座部１４の頂面に第１実施形態におけるファスナー部１５に替えてボス部１５Ａを設けて、該ボス部１５Ａを介して内周側トリム１Ｂをビス１６によりねじ止めして接続するようにしている。   Further, in the illustrated example, a boss portion 15A is provided on the top surface of the seat portion 14 in place of the fastener portion 15 in the first embodiment, and the inner peripheral side trim 1B is screwed with a screw 16 via the boss portion 15A. And try to connect.

従って、本実施形態によれば前記第１実施形態の作用効果に加えて、車両の衝突時等に乗員頭部Ｈが外周側トリム１Ａの間接照明装置１０の配設相当部分に干渉して、エネルギー吸収部３０を構成するハウジング１１の座部１４に所定値以上の衝突荷重Ｆが入力すると、上述のように該座部１４の座屈変形により衝突エネルギーを吸収して優れた緩衝効果を得ることができる。   Therefore, according to the present embodiment, in addition to the operational effects of the first embodiment, the occupant head H interferes with the arrangement of the indirect lighting device 10 of the outer trim 1A at the time of a vehicle collision or the like, When a collision load F of a predetermined value or more is input to the seat portion 14 of the housing 11 constituting the energy absorbing portion 30, the collision energy is absorbed by the buckling deformation of the seat portion 14 as described above, and an excellent buffering effect is obtained. be able to.

そして、専用のエネルギー吸収部材を用いないので、レイアウトが困難となることがなく、しかも、部品点数や取付工数が嵩むこともないのでコスト的に有利に得ることができる。   Since no dedicated energy absorbing member is used, the layout does not become difficult, and the number of parts and the number of mounting steps are not increased, which can be advantageously obtained in terms of cost.

また、このような衝突荷重Ｆの入力に関しては、前記第１実施形態を含めて、外周側トリム１Ａの端末には前記特許文献１の如き別部材のカバーモールが室内に露出して設けられていないので、このカバーモールの破損による不具合を生じることもない。   Further, regarding the input of such a collision load F, including the first embodiment, a cover molding as a separate member as in the above-mentioned Patent Document 1 is provided indoors at the terminal of the outer peripheral side trim 1A. Therefore, there is no problem caused by the damage of the cover molding.

図４は本発明の第３実施形態を示すもので、本実施形態では前述の内周側トリム１Ｂは、外周側トリム１Ａとオーバーラップして配置した端部に、外周側トリム１Ａに乗員頭部Ｈの衝突荷重Ｆが作用した場合に、車体パネルであるルーフサイドレール２３との間で潰れ変形可能なエネルギー吸収部３０を備えている。   FIG. 4 shows a third embodiment of the present invention. In this embodiment, the above-mentioned inner peripheral trim 1B is disposed on the outer trim 1A at the end portion that overlaps the outer trim 1A. When the collision load F of the part H acts, the energy absorption part 30 which can be crushed and deform | transformed between the roof side rails 23 which are vehicle body panels is provided.

図示する例では、内周側トリム１Ｂの間接照明装置１０を介して連結した部分よりも車幅方向外側に、部分的にあるいは長さ方向（車両前後方向）に沿って延設部を形成して、ここに下側が開放した凹形の開断面部９を形成し、該開断面部９をもって外周側トリム１Ａの背面に当接して定置されるエネルギー吸収部３０を構成している。   In the illustrated example, an extending portion is formed partially or along the length direction (vehicle longitudinal direction) on the outer side in the vehicle width direction than the portion connected via the indirect lighting device 10 of the inner peripheral trim 1B. Thus, a concave open cross-section portion 9 whose lower side is opened is formed here, and the energy absorption portion 30 that is placed in contact with the back surface of the outer peripheral side trim 1A with the open cross-section portion 9 is configured.

また、本実施形態の場合も前記第２実施形態と同様に、ハウジング１１の座部１４の頂面にボス部１５Ａを設けて、該ボス部１５Ａを介して内周側トリム１Ｂをビス１６によりねじ止め固定するようにしている。   Also in this embodiment, as in the second embodiment, a boss portion 15A is provided on the top surface of the seat portion 14 of the housing 11, and the inner peripheral trim 1B is screwed by a screw 16 via the boss portion 15A. It is fixed with screws.

従って、本実施形態によれば前記第１実施形態の作用効果に加えて、車両の衝突時等に乗員頭部Ｈが外周側トリム１Ａにおける前記エネルギー吸収部３０の配設相当部分に干渉して、所定値以上の衝突荷重Ｆが入力すると、このエネルギー吸収部３０を構成する内周側トリム１Ｂの開断面部９が車体側パネル２３との間で座屈変形することにより衝突エネルギーを吸収して優れた緩衝効果を得ることができる。   Therefore, according to the present embodiment, in addition to the operational effects of the first embodiment, the occupant head H interferes with the arrangement of the energy absorbing portion 30 in the outer trim 1A during a vehicle collision or the like. When a collision load F of a predetermined value or more is input, the open cross-section portion 9 of the inner peripheral side trim 1B constituting the energy absorbing portion 30 is buckled and deformed with the vehicle body side panel 23 to absorb the collision energy. And an excellent buffering effect can be obtained.

また、本実施形態の場合も専用のエネルギー吸収部材を用いないので、レイアウトが困難となることはなく、しかも、部品点数や取付工数が嵩むこともないのでコスト的に有利に得ることができる。   Also, in the case of this embodiment, since a dedicated energy absorbing member is not used, the layout is not difficult, and the number of parts and the number of mounting steps are not increased, so that it can be advantageously obtained in terms of cost.

なお、前記実施形態では本発明をルーフトリムに適用した場合を例示したが、この他、ドアトリム、リヤサイドトリム、リヤピラートリム等の室内サイドトリムに本発明を採用することができる。   In addition, although the case where this invention was applied to the roof trim was illustrated in the said embodiment, this invention is employable also for interior side trims, such as a door trim, a rear side trim, a rear pillar trim.
