Description

【考案の詳細な説明】 《産業上の利用分野》 本考案は、車両のルーフパネル内側に張設され
る成形天井に関する。
《従来の技術》 車両用成形天井は、車両室内の美観、乗員の安
全性の向上等の目的で、車両のルーフパネル内側
に張設されるものである。
この成形天井は、第５図に示すように、基材で
あるダンボール１と表皮材２とを樹脂系接着剤と
してのホツトメルト３を介して積層し、ルーフパ
ネル４の内側形状に合わせて加熱加圧成形して、
その周縁部を図示しないガーニツシユやボデーサ
イドウエルト等によつてルーフパネル４側に支持
されて張設される。
そして、従来、接着剤としてのホツトメルト３
は、ダンボール１と表皮材２とを互いに接合させ
ることだけを目的として、これらの間に薄く均一
な厚さに塗布または貼付されている。
《考案が解決しようとする問題点》 ところが、ダンボール１は湿気を吸収すると元
の形状に戻ろうとして外側へ変形するため、第５
図に示すように、ルーフパネル４の端末形状と合
わなくなつてルーフパネル４に取り付けることが
できなくなるおそれがある。
本考案は、湿気を吸収してもルーフパネル確実
に取り付けることができる車両用成形天井を提供
することを目的とする。
《問題点を解決するための手段》 このため本考案の車両用成形天井は、表皮材と
基材としてのダンボールとを樹脂系接着剤を介し
て積層し、車体のルーフパネル内側に沿つた形状
に成形される車両用成形天井であつて、前記接着
剤を天井の中央部よりも周辺部で厚くしたことを
特徴としている。
《作用》 湿気を吸収した基材としてのダンボールがルー
フパネル側である外側へ変形しようとすると、そ
の内側に塗付された樹脂系接着剤の収縮よつて内
側へ引かれ外側への変形が押えられる。特に、基
材のうち絞り率の大きい天井周縁部では、厚く貼
付した接着剤により基材の外側への変形が確実に
押えられる。
これにより、成形天井は、基材が湿気を吸収し
ても、外側へ変形することはなく、確実にルーフ
パネルに取り付けることができる。
《実施例》 本考案の車両用成形天井は、前述した従来例と
略同様な構造を有しており、第１図に示すよう
に、基材としてのダンボール１１と表皮材１２と
を樹脂系接着剤としてのホツトメルト１３を介し
て積層し、ルーフパネル１４の内側形状に合わせ
て加熱加圧成形して、その周縁部を図示しないガ
ーニツシユやボデーサイドウエルト等によつてル
ーフパネル１４側に支持されて取り付けられる。
ダンボール１１は、第３図および第４図に示す
ように、上下二枚のライナー１６，１７と、これ
ら二枚のライナー１６，１７の相対向する面にそ
れぞれ配設されたポリエチレンフイルム１６ａと
１７ａと、二枚のライナー１６，１７の間に介装
される波板状の中芯１８とから構成されており、
このダンボール１１をルーフパネル１４の内側形
状に合わせて熱プレス成形し、その表面にフイル
ム状のホツトメルト１３を介して表皮材１２を積
層してさらに熱プレス成形し、第２図に示すよう
な内側成形天井１９を得る。なお、表皮材１２と
してはポリエステル製の不織布やトリコツトが用
いられている。
成形天井１９の周辺部のうち特に絞り率の大き
い長手方向両端部１９ａ，１９ｂ（第２図中の破
線のハツチングで示す部分）には、第１図に示す
ように、フイルム状のホツトメルト１３が厚く配
設されている。そして、成形天井１９の中央付近
では、絞り率が小さいため湿気吸収による変形が
小さく、ホツトメルト１３は薄くなつている。
ホツトメルト１３の厚さを具体的な数値を用い
て説明する。ここで用いる成形天井１９は、小型
あるいは中型乗用車に用いるもので、ダンボール
１１の二枚のライナー１６，１７は目付量280〜
300ｇ／m2、ポリエチレンフイルム１６ａ，１７
ａは厚さ25〜50μｍ、中芯１８は目付量220ｇ／
m2で、表皮材１２は目付量200〜300ｇ／m2のもの
が用いられている。
ホツトメルト１３を厚く配設する成形天井１９
の長手方向両側部１９ａ，１９ｂは、それぞれ幅
が150〜200mmで、ホツトメルト１３の厚さは75〜
100μｍとなつている。そして、長手方向両側部
１９ａ，１９ｂを除く部分でのホツトメルト１３
の厚さは30〜50μｍとなつてるい。
以上のように構成された成形天井１９では、加
熱加圧成形された後湿気を吸収しても、それによ
つてダンボール１１が外側へ変形しようとする力
より、収縮性を有するホツトメルト１３がダンボ
ール１１を内側へ変形させようとする力の方が大
きく、ダンボール１１の外側への変形がなくな
る。特に、外側へ変形しようとする力の大きい長
手方向両側部１９ａ，１９ｂには、ホツトメルト
１３を厚くしたので、ダンボール１１の外側への
変形が確実に押えられる。
これにより、成形天井１９は、湿気による影響
を受けずにルーフパネル１４に確実に取り付ける
ことができる。
なお、第１図に示すようにダンボール１１の内
側への変形は、その取付け構造上問題にならな
い。その理由は、周縁部が内側へ変形したダンボ
ール１１の場合、ルーフパネル１４に当接した
後、周縁部を外側へ押し広げて、ボデーサイドウ
エルト等によつてルーフパネル１４に取り付けら
れるからである。
また、本実施例では、ホツトメルト１３をダン
ボール１１の長手方向両側の周辺部に厚くした
が、前後方向両側の周辺部も同様に厚くしてもよ
く、また周辺部に限らず、絞り率が大きく外側へ
変形しやすい部分であれば、その部分のホツトメ
ルト１３を厚くすることで、前記同様の作用・効
果を得ることができる。
《考案の効果》 本考案の車両用成形天井では、収縮性を有する
樹脂性接着剤の厚さを適宜調整することにより、
基材が湿気を吸収しても外側へ変形することはな
く、ルーフパネルに確実に取り付けることができ
る利点がある。
