Description

【０００１】
【発明の属する技術分野】
本発明は自動車の側面衝突時に車体パネルが車内側に変形するのを防止又は抑制して乗員保護性能を高めると共に、車両側面の意匠効果を高めることができる車両用補強兼装飾部材に関する。
【０００２】
【従来の技術】
車両用の補強部材としては、例えば特開平５−３０１５２２号公報に示されているように、ドアアウタパネルの外側面にインパクトビームを前後方向に取付け、該インパクトビームの前後端の取付部分をカバーで覆って、該インパクトビーム自体にサイドプロテクションモールの機能を持たせたものが知られている。
【０００３】
【発明が解決しようとする課題】
しかし、前記従来の車両用補強部材では、インパクトビームの形状がそのままサイドプロテクションモールの形状となるので、サイドプロテクションモールとしての意匠に制限を受ける不都合がある。また、この先行技術では、意匠性を優先すると補強機能を維持できないことがあり、いずれの場合にも製品設計の自由度に、制限を受けることがある。
【０００４】
そこで、本発明はインパクトビームとして適切な強度が得られると共に、サイドプロテクションモールとして所望の適切な意匠効果を得ることができる車両用補強兼装飾部材を提供しようとするものである。
【０００５】
【課題を解決するための手段】
請求項１にあっては、車両側面の車外側パネル面にほぼ前後方向に取り付けられる長尺な部材であって、該部材は剛性を有し、車両の側面衝突時の衝突荷重に対抗して車外側パネルの車内側への変形を防止又は抑制して梁として機能するのに十分な曲げ強度を有する長尺な骨格体と、この骨格体とは異なり相対的に軟かい材料で異なる形状に成形され、該骨格体に一体化され、この外側面を全体的に覆って所望の意匠を呈する装飾体とを備えた補強兼装飾部材として形成されていて、骨格体を内部に中空部を有する長尺な中央部分と、この中央部分の内部の中空部に内接嵌合された挿入部分を備えて該中央部分の両端に一体的に設けられた端末部分とで構成し、各端末部分は補強兼装飾部材を車外側パネル面に取り付ける連結手段を備え、補強兼装飾部材を連結手段で車外側パネルの前後端部に固着して実質的に両端固定梁として作用させると共に、前記衝突荷重が作用した時の支点として働くようにしたことを特徴としている。
【０００６】
この請求項１の構成によれば、車両の側面衝突時には、骨格体の中央部分で受けた衝突荷重を端末部分からピラー等の車両骨格部材へ分散して、車体パネルの車内側への変形量を小さく抑えて、乗員の保護性能を向上することができる。
【０００７】
また、骨格体を覆う装飾体が所望の意匠を呈することにより、車両側面の意匠効果を高めることができる。
【０００８】
請求項２にあっては、請求項１に記載の車両側面の車外側パネル面にほぼ前後方向に沿って車内側に向けて突出するように形成された凹溝に骨格体の車内側の一部を収容し車外側の一部を該パネル面から突出させて取付け可能としたことを特徴としている。
【０００９】
この請求項２の構成によれば、車外側パネル面の凹溝に骨格体の車内側の一部を収容し車外側の一部を突出させたことにより、補強兼装飾部材の車外側パネル面より突出する量を少なくして、規定の車幅寸法を得る場合に有利となる。
【００１０】

【００１２】
請求項４にあっては、請求項３に記載のパイプ状の長尺材を高張力鋼板で形成したことを特徴としている。
【００１３】
この請求項４の構成によれば、中央部分を高張力鋼板で形成したことにより、中央部分の厚さを薄くして軽量化を図ることができると共に、衝突荷重に対する適切な耐曲げ強度を得ることがことができる。
【００１４】
請求項５にあっては、請求項３に記載のパイプ状の長尺材を押し出し成形品で形成したことを特徴としている。
【００１５】
この請求項５の構成によれば、中央部分を押し出し成形品で形成したことにより、中央部分の成形性を向上することができる。
【００１６】
請求項６にあっては、請求項１〜５に記載の装飾体をゴム又は合成樹脂の成形品で形成したことを特徴としている。
【００１７】
この請求項６の構成によれば、歩行者等に対する安全性が向上するとともに装飾体の所望の意匠を表現する形状を容易に作ることができる。
【００１８】
請求項７にあっては、請求項６に記載の装飾体の表面に該装飾体を構成する材料自体の色とは異色の表面処理を施したことを特徴としている。
【００１９】
この請求項７の構成によれば、装飾体の表面に色による表面処理を施したことにより、車外側パネル面の塗装色との適合を図ることができる。
【００２０】
請求項８にあっては、請求項１〜７に記載の端末部分は中央部分の内部の中空部に内接嵌合される挿入部分を備えていると共に、連結手段はこの挿入部分に設けられた第１の連結要素を含み、該第１の連結要素は車外側パネルを挾んで第２の連結要素と結合可能にされていることを特徴としている。
【００２１】
この請求項８の構成によれば、連結手段の第１連結要素と第２連結要素とによって補強兼装飾部材の車外側パネルへの装着と伴せて、骨格体の端末部分と中央部分との一体化を図れ、補強兼装飾部材の強度剛性を向上することができる。
【００２２】
請求項９にあっては、請求項８に記載の端末部分を中央部分に接合したことを特徴としている。
【００２３】
この請求項９の構成によれば、端末部分と中央部分とを予め一体化してあるため、骨格体と装飾体との型成形性を向上することができる。
【００２４】
請求項１０にあっては、請求項１〜９に記載の骨格体の内部の中空部でドア開閉時の加速度の影響の少ない部分に車外側からの衝撃によって発生する加速度を検出するセンサを配置したことを特徴としている。
【００２５】
この請求項１０の構成によれば、骨格体の内部空間を有効利用してセンサを配置できて側面衝突時の加速度をより直接的にかつ確実に検出でき信頼性を高めることができる。
【００２６】
【発明の実施の形態】
以下、本発明の実施形態を説明する。
【００２７】
図１〜図５において、１は車両の側面を構成するフロントドア５２、リヤドア５３、フロントフェンダー５４、リヤフェンダー５５等の車外側パネル面に前後方向に取り付けられる長尺な補強兼装飾部材であって、本実施形態では補強兼装飾部材１をすでに塗装済のフロントドア５２やリヤドア５３におけるドアアウターパネル３１の車外側面に前後方向に形成された凹溝３３に直線状に取り付けた場合を一例として図示してある。
【００２８】
この補強兼装飾部材１は車両の側面衝突時の衝突荷重Ｆに対抗してドアアウターパネル３１の車内側への変形を防止又は抑制して梁として機能するのに十分な耐曲げ強度を有するパイプ状の骨格体２と、この骨格体２の外側を全体的に覆う装飾体３とを備えている。
【００２９】
骨格体２はドアアウターパネル３１よりも厚い板厚を有し、引張強度が５０ｋｇｆ／ｍｍ²以上の強度を有し、好ましくは８０Ｋｇｆ／ｍｍ²〜１５０ｋｇｆ／ｍｍ²、最も好ましくは１００ｋｇｆ／ｍｍ²前後の強度で板厚が１．０ｍｍ〜２．５ｍｍ程度の高張力鋼板をロール成形して溶接したパイプ（電縫管）やアルミニウム合金を押し出し成形したパイプ等からなる金属製角形パイプの中央部分４と、この中央部分４の両端に一体的に設けられた金属製の端末部分５，６とを備えている。
【００３０】
端末部分５，６は中央部分４の内部に内接嵌合される挿入部５ａ，６ａと、これらの挿入部５ａ，６ａの後端より外側に突出する頭部５ｂ，６ｂとを備えており、挿入部５ａ，６ａを中央部分４の端部より内部に挿入すると共に、頭部５ｂ，６ｂを中央部分４の端部に当接して、該頭部５ｂ，６ｂと中央部分４との当接部分の外周面を溶接７，８にて治金的に接合してある。
【００３１】
各端末部分５，６の挿入部５ａ，６ａの車内側面には連結手段の第１連結要素としてのねじ孔９，１０を形成してある。
【００３２】
これらのねじ孔９，１０と対向する骨格体２の車内側面には連結手段の第２連結要素としてのボルト１１，１２の軸部を挿入する貫通孔１３，１４を形成してある。
【００３３】
装飾体３はゴムや合成樹脂のインジェクション成形で別に予め形成しておいたものを後工程で骨格体２に嵌め込んで組み立てたり、あるいは端末部分５，６を備えた骨格体２をインサートとし、この骨格体２をインジェクション成形型内に載置して型内にゴムや合成樹脂を射出して装飾体３を成形するとともに骨格体２に一体化する（通称、インサートインジェクション法）こともできる。なお、インジェクション成形は、加熱溶融したゴムや合成樹脂材料を使用する通常のインジェクション成形に代えてＲＩＭ（反応射出成形）を適用することもでき、あるいはインジェクション・コンプレッション成形などでもよい。
【００３４】
以上の通り、装飾体３は成形型を用いて形成するものであるから、骨格体２の形状に制約されることなく所望の意匠を呈する比較的自由な形状に容易に成形できる。
【００３５】
装飾体３を形成する材料としては、ゴムの他に、通常のインジェクション成形によるときは、ＰＶＣ，ＰＰ，ＰＰＥ，ＡＢＳ，ＴＰＵ（熱可塑性ウレタン）樹脂等を用いることができ、ＲＩＭ成形を用いるときはポリオールとイソシアネートの混合によるポリウレタン樹脂とすることができる。
【００３６】
本実施形態の補強兼装飾部材１をドアアウターパネル３１に取り付けた場合において、図１に示すようにフロントドア５２又はリヤドア５３を車体に開閉可能に取り付けるドア側ヒンジ５１寄りの装飾体３の車外側面には欠如部１５を有段形成して、この欠如部１５によりフロントドア５２が開けられた際に装飾体３が車体のフロントフェンダー５４の後端縁部分に接して干渉したり、リヤドア５３が開けられた際に装飾体３がフロントドア５２の後端縁、又はフロントドア５２に取付けられた補強兼装飾部材の後端に干渉するのを防止するようにしてある。
【００３７】
また、図２及び図３に示すように、装飾体３の車外側面は、傾斜状の上側意匠面１６と、段差部１７を有する主意匠面１８と、傾斜状の下側意匠面１９とを備えている。更に、骨格体２が塗装したドアアウターパネル３１と直接に接触して塗膜面を傷つけるのを防止するため装飾材３の一部を骨格体２の両側及び車内側まで延長させて緩衝材部１６ａ，１９ａを形成しておくのが好ましい。
【００３８】
また、図４に斜線で示すように装飾体３の上側意匠面１６と主意匠面１８の段差部１７よりも上位面及び欠如部１５の上半面にはドアアウターパネル３１と同色の第１の色の塗装２１を施してあり、図４に網目で示すように主意匠面１８の段差部１７よりも下位面と下側意匠面１９及び欠如部１５の下半面にはドアアウターパネル３１の車外側面に仕上げ塗装される色と異なる第２の色の塗装２２を施してある。これによって、補強兼装飾材１をドア５２，５３の比較的上部に取り付けたとしても下部寄りに取り付けた様な外観を呈させることができ、車両のタイプにより適した位置と外観を両立させることができる。また装飾体３の幅を実際よりも細く見えさせることができる。
【００３９】
補強兼装飾部材１をドアアウターパネル３１に取り付けるには、図１に示すように、先ず、補強兼装飾部材１をその骨格体２の貫通孔１３，１４をドアアウターパネル３１側に向けてドアアウターパネル３１の凹溝３３に収容して、骨格体２より前後に延設された装飾体３の前端及び後端部の裏面に装着された両面粘着テープ等のような接着部材２３，２４をドアアウターパネル３１のドアインナーパネル３２と巻締め結合された前後縁に接着することにより、補強兼装飾部材１をドアアウターパネル３１に仮止めする。なお、装飾体３の幅は装飾性を向上させる為に凹溝３３の幅よりもやや大きくするのが好ましい。
【００４０】
次に、ドアインナーパネル３２の前端縁よりも内側に形成された膨出部３４と、該膨出部３４とドアアウターパネル３１との間に介装されたビームブラケット３５の相互に形成された作業孔３６より該ビームブラケット３５とドアアウターパネル３１との相互に形成された貫通孔３７及び骨格体２の貫通孔１３にボルト１１を、好ましくは高力ボルト１１をワッシャを介して通してねじ孔９に締結する一方、ドアインナーパネル３２の後端縁よりも内側に形成された段差３８と、該ドアインナーパネル３２とドアアウターパネル３１との間に介装されたビームブラケット３９の相互に形成された貫通孔４０より骨格体２の貫通孔１４に上記と同様にボルト１２を通してねじ孔１０に締結する。なお、ビームブラケット３５，３９は引張強度５０ｋｇｆ／ｍｍ²〜８０ｋｇｆ／ｍｍ²程度の強度で板厚２．０ｍｍ〜５．０ｍｍ程度の高張力鋼板のプレス成形品が好ましく、側面衝突時の荷重を支持して広い範囲に分散させる作用をする。
【００４１】
本実施形態の場合、図１に示すようにビームブラケット３５，３９はドアインナーパネル３２に対接面でスポット溶接され、更に端縁部でアーク等で溶接４１，４２，４３，４４にて接合してあり、図２に示すようにドアインナーパネル３１の凹溝３３を抱持するブラケット３９の端部はドアアウターパネル３１に溶接４５，４６にて接合してある。この場合溶接４５，４６は補強兼装飾部材１を取付けると外部からは目視されない。
【００４２】
また、図１に示すようにドアヒンジ５１側で、ドア開閉時に発生する横方向の加速度の影響の少ない端末部分５の先端面に形成された収容孔２５には外側からの衝撃によって発生する加速度を検出するセンサ４７を装着してある。
【００４３】
このセンサ４７よりリード線として延設されたハーネス４８は、樹脂グロメット５０を備えた電線用孔２６と４９を通してドア内部に引き出されている。
【００４４】
このハーネス４８は、車両の側面衝突時にセンサ４７がある一定値以上の横方向の加速度を検出したらその送信を送る為に、図外のシートベルトを引き締めて乗員を拘束するシートベルトのプリテンショナーシステムやサイドエアバックシステム等を駆動する制御装置の入力部に接続される。
【００４５】
自動車の側面衝突時には、一般的に側面ドアやフェンダーに荷重を受ける場合が多いが、荷重を受ける部分又はその近くに加速度センサーを設けることにより加速度を直接的、確実に加速度を検出できるので信頼性を向上させることができる。
【００４６】
また、前記ドアインナーパネル３２の膨出部３４とドアアウターパネル３１との間には、図外のドアウインドウパネル及びその昇降用のウインドウレギュレータ等が格納される。
【００４７】
本実施形態の構造によれば、車両の側面衝突時に補強兼装飾部材１が衝突荷重Ｆを受けると、該補強兼装飾部材１の骨格体２がこの衝突荷重Ｆに対抗してフロントドア５２やリヤドア５３の車内側への変形量を小さくして乗員の保護性能を向上することができる。
【００４８】
また、前記衝突荷重Ｆが作用して、骨格体２の中央部分４が車内側に変形するような場合にあっても、骨格体２の中央部分４で受けた衝突荷重Ｆを端末部分５，６からビームブラケット３５，３９を介して図外のピラー等の車両骨格部材へ分散してフロントドア５２やリヤドア５３の車内側への変形量を少なく抑えることができる。
【００４９】
また、骨格体２が衝突荷重Ｆを負担し得る耐曲げ強度を有し、この骨格体２を覆う装飾体３が所望の意匠を呈することにより、ドア側面の意匠効果を高めることができる。
【００５０】
一方、この実施形態では補強兼装飾部材１の車内側の一部をドアアウターパネル３１の前後方向に沿って車内側に突出するよう形成された凹溝３３に収容し車外側の一部を突出させてあるので、補強兼装飾部材１がドアアウターパネル３１の車外側面より突出する量を少なくして、規定の車幅寸法内に収めることができるとともに、隣り合って駐車した他の車両のドアが開いて接したときでも、他の車両のドア縁を突出した部分で受けとめて、車体パネル３１に傷がつくのを防止できる。また歩行者等がこの突出部に接しても安全である。
【００５１】
また、補強兼装飾部材１をドアアウターパネル３１に取付けるボルト１１，１２により骨格体２の端末部分５，６と中央部分４とを一体化できて強度剛性を高めることができる。
【００５２】
更に、該骨格体２はその端末部分５，６を中央部分４に予め接合してあることから、骨格体２に一体的に装飾体３を樹脂成形型を用いて成形する場合に装飾体３を形成する材料が骨格体３の内部に流れ込んでゆかず成形性を向上することができる。
【００５３】
図６は本発明の第２実施形態を示し、この図において、補強兼装飾部材１の骨格体２に連結手段の第１連結要素としてボルト５５を設けてある。
【００５４】
このボルト５５はそのねじ部を骨格体２の中央部分４の車内側面より突出させ、頭部は骨格体２の中央部分４の車外側面に形成された貫通孔５６から端末部分５の挿入部５ａの車外側面に形成された凹部５７に収容して該凹部５７まわりに溶接５８にて接合している。
【００５５】
補強兼装飾部材１はドアアウターパネル３１に前記実施形態と同様に仮止めした後に、作業孔３６よりナット５９をボルト５５のねじ部に締結することにより、取り付けることができる。
【００５６】
図７は本発明の第３実施形態を示し、骨格体２の中央部分４が複数のパイプ状の第１，第２部材６０，６１と、これらを結合する車外側，車内側保持板６３，６４とを備え、車外側，車内側保持板６３，６４を第１，第２部材６０，６１に溶接にて接合して、衝突荷重Ｆに対抗し得る曲げ強度を高めるように構成してある。
【００５７】
本実施形態の構造によれば、中央部分４の曲げ強度を第１，第２部材６０，６１と車外側，車内側保持板６３，６４とで高められることにより、該中央部分４の横幅を小寸法に形成することができて、補強兼装飾部材１の横幅を全体的に小さくでき、該横幅を小寸法に形成した分だけ、補強兼装飾部材１を収容するドアアウターパネル３１に形成される凹溝３３の深さを浅く形成できて、ドア内のスペースを大きく確保したいときに有用である。
【００５８】
また、この実施形態の場合第１，第２部材６０，６１の機械的強度、寸法、材質を選択して組み合わせることによって対荷重性能を調整することもできる。
【００５９】
図８は本発明の第４実施形態を示し、骨格体２の中央部分４が複数のパイプ状の第１，第２部材６０，６１を互いに突き合わせて、該突き合わせ部分を溶接６５，６６にて接合して、衝突荷重Ｆに対抗し得る曲げ強度を高めるように構成してある。
【００６０】
本実施形態の構造によれば、第１，第２部材６０，６１を互いに突き合わせて溶接６５，６６にて接合したことにより、第１，第２部材６０，６１の互いに突き合わされた部分が衝突荷重Ｆに対する補強リブとして作用して、中央部分４の耐曲げ強度を高めることができると共に、部品点数を少なくしてコストダウンを図ることができる。
【００６１】
図９は本発明の第５実施形態を示し、骨格体２の中央部分４が円形のパイプ材（電縫管）６７により形成してある。この場合にはパイプ材を安価に製造し、又は購入できる。
【００６２】
図１０は本発明の第６実施形態を示し、骨格体２の中央部分４がかまぼこ形のパイプ材６８により形成されて、該パイプ材６８の半円形凸部を衝突荷重Ｆ方向に向けて配置するようにしている。
【００６３】
図１１は本発明の第７実施形態を示し、骨格体２の中央部分４が内部にリブ６９を一体に有する角形のパイプ材７０により形成されて、該パイプ材７０のリブ６９を衝突荷重Ｆ方向に向けて配置するようにしてあり、この実施形態の場合アルミニウム合金等の押出し成形によって容易に得ることができる。
【００６４】
図１２は本発明の第８実施形態を示し、図９〜１１に示す実施形態の中央部分４を構成するパイプ材に相当するパイプ材７１の端末部分５を挿入する部分以外の部分の側面を、実線示から仮想線示のように液圧バルジ加工により膨出成形してある。
【００６５】
本実施形態の構造によれば、パイプ材７１の膨出により、衝突荷重Ｆに対する耐曲げ強度を一段と高めることができる。
【００６６】
図１３は本発明の第９実施形態を示し、骨格体２の中央部分４が高張力鋼板を曲げ加工してかまぼこ形に形成されたパイプ材７２により構成されて、該パイプ材７２の半円形凸部を衝突荷重Ｆ方向に向けていると共に、該パイプ材７２の縫合線７３を溶接７４にて接合して車内側に向けている。
【００６７】
図１４は本発明の第１０実施形態を示し、骨格体２の中央部分４が高張力鋼板を曲げ加工して内部にリブ７５を有する角形に形成されたパイプ材７６により構成されて、該パイプ材７６のリブ７５を衝突荷重Ｆ方向に向けていると共に、該リブ７５を構成する二重壁の車内側に位置する合わせ部分を溶接７７にて接合している。
【００６８】
図１５は本発明の第１１実施形態を示し、骨格体２の中央部分４が高張力鋼板を曲げ加工して内部にリブ７８を有するかまぼこ形に形成されたパイプ材７９により構成されて、該パイプ材７９のリブ７８を衝突荷重Ｆ方向に向けていると共に、該リブ７８を構成する二重壁の車外側に位置する凹状の合わせ部分を溶接８０にて接合している。
【００６９】
これらの実施形態のように、中央部分４を高張力鋼板を曲げ加工して構成すれば、パイプ材の板厚を薄くして軽量化を図ることができて、しかも、衝突荷重Ｆに対する適切な耐曲げ強度を得ることができる。
【００７０】
なお、この実施形態のように、パイプ材７９の断面形状が比較的複雑で部分的に加工度合が高くなるものでは高強度（例えば１２０ｋｇｆ／ｍｍ²以上）の高張力鋼板を用いると割れ等が発生しやすいので、低〜中（例えば５０ｋｇｆ／ｍｍ²〜１００ｋｇｆ／ｍｍ²）強度のものを用いるとよい。
【００７１】
図１６は本発明の第１２実施形態を示し、骨格体２の中央部分４を構成するパイプ材８１の内部で端末部分５を挿入する部分以外に硬質ポリウレタン樹脂の発泡体８２を充填してある。
【００７２】
本実施形態の構造によれば、中央部分４が衝突荷重Ｆで車内側に変形する際に、発泡体８２が抵抗として作用するので、パイプ材８２の板厚を薄くしても、衝突荷重Ｆに対する曲げ強度を向上することができる。
【００７３】
図１７は本発明の第１３実施形態を示し、骨格体２の端末部分５，６を金属の鍛造品で形成し、一方の端末部分５の車内側面にねじ孔９を形成し、他方の端末部分６の車内側面にボルト５５を結合している。
【００７４】
本実施形態の構成によれば、端末部分５，６を金属の鍛造品で形成したことにより、端末部分５，６の頭部５ｂ，６ｂの厚さに変化を持たせることができる。
【００７５】
図１８は本発明の第１４実施形態を示し、骨格体２の端末部分５，６に相当する端末部分８３を鋼板のプレス成形品で形成すると共に、該端末部分８３の車内側壁に貫通孔８４を形成して、該貫通孔８４まわりの内面にナット８５を溶接８６にて接合している。
【００７６】
本実施形態の構成によれば、端末部分８３を鋼板のプレス成形品で形成したことにより、端末部分８３の軽量化を図ることができる。
【００７７】
図１９は本発明の第１５実施形態を示し、補強兼装飾部材１を車両の側面を構成するフロントフェンダー５４、フロントドア５２、リヤドア５３及びリヤフェンダー５５のそれぞれの車外側面に前後方向に全体を大きな曲率半径Ｒを呈する弧状に取り付ければ、車両の前後方向に一連の意匠を表現することができる。
【００７８】
なお、図示は省略するが、骨格体２の中央部分４を金属以外のＦＲＰ（繊維強化樹脂）、特に、ＣＦＲＰ（カーボン繊維強化樹脂）を積層成形したパイプでも構成することもできる。
【００７９】
また、骨格体２の端末部分５，６を鋼材の鍛造品やプレス成形品以外のアルミニウム合金や亜鉛合金などのダイカスト成形品、ＦＲＰ成形品等で構成してもよい。
【００８０】
この骨格体２の中央部分４や端末部分５，６の一方又は両方を金属以外で形成した場合には溶接に代えて両者を接着剤等で化学的に接合すればよい。
【００８１】
なお、本願において、梁という用語は荷重のかかる方向とは無関係に、材料力学的な用語として用いている。
【００８２】
前記の実施形態の説明において、装飾体３は骨格体２の外側面全体を覆うものとして説明したが、骨格体２の外表面が例えばステンレス鋼板のように装飾性を有するものを使用するときには骨格体の一部分を長手方向に沿って露出させてもよく、また他に、装飾体３の表面に異色の装飾条片を被着してもよい。
【００８３】
