自動車の車体天井の室内側に張設される天井内装は前記
バットに樹脂発泡材を用い、この表面を樹脂材からなる
表皮材で覆う方法がとられている。Problems to be Solved by the C0 Invention The ceiling interior installed on the interior side of the ceiling of an automobile body uses a resin foam material for the bat and covers the surface with a skin material made of resin material. .
したがって剛性が低くこれらの天井内装材が室内側に撓
み易いという問題点がある。そしてルーフパネル全体の
剛性を高めるため、その補強材として前記天井内装材を
活用することは非常に好ましいことであった。Therefore, there is a problem that the rigidity of these ceiling interior materials is low and they tend to bend toward the indoor side. In order to increase the rigidity of the entire roof panel, it is highly desirable to utilize the ceiling interior material as a reinforcing material.
ｄ、 問題点を解決するための手段
本発明は前記事情に鑑みてなされたもので、室内側の外
観を損うことなく、ルーフ並びにその天井内装の剛性を
向上させた自動車の天井内装構造を提供しようとするも
のである。d. Means for Solving the Problems The present invention has been made in view of the above circumstances, and provides an automobile ceiling interior structure that improves the rigidity of the roof and its ceiling interior without impairing the exterior appearance of the interior. This is what we are trying to provide.
すなわち、本発明は自動車のルーフパネルの室内側に樹
脂発泡材からなる天井内装材を装着する場合において、
前記天井内装材に所定間隔を置いて多数の溝を圧縮形成
するとともに、該溝の底部を圧縮強化し、このように構
成した天井内装材を前記ルーフパネルに接着固定したこ
とを特徴とする自動車の天井内装構造である。That is, the present invention provides a method for installing a ceiling interior material made of a resin foam material on the indoor side of a roof panel of an automobile.
An automobile characterized in that a large number of grooves are compressed and formed in the ceiling interior material at predetermined intervals, the bottoms of the grooves are compressed and strengthened, and the ceiling interior material configured in this manner is adhesively fixed to the roof panel. This is the ceiling interior structure.
以下、本発明の実施例について図面を参照しながら詳細
に説明する。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図〜第６図において、１は乗用自動車、２は乗用自
動車１のルーフパネル、３．４は乗用自動車ｌの前後面
のウィンドガラス、５はルーフパネル２の内側に張設さ
れた天井内装材である。1 to 6, 1 is a passenger car, 2 is a roof panel of the passenger car 1, 3.4 is a front and rear windshield of the passenger car 1, and 5 is a ceiling stretched inside the roof panel 2. It is an interior material.
天井内装材５は、第１図に示すようにルーフパネル２の
内側形状に合せて、はりその全域を覆うように形成され
、一定間隔を置いて複数の溝５ａが左右方向に両端部か
ら設けである。As shown in FIG. 1, the ceiling interior material 5 is formed to match the inner shape of the roof panel 2 so as to cover the entire area of the beam, and a plurality of grooves 5a are provided at regular intervals from both ends in the left and right direction. It is.
この天井内装材５は樹脂発泡材、たとえば発泡ウレタン
５ｂからなり、必要に応じ適所にグラスファイバーによ
って補強しである。すなわち、発泡ウレタン５ｂからな
る天井内装材５に対し、これを圧縮して溝５ａを形成し
、この溝５ａの底部５ｃの外側の圧縮部分を強化する。This ceiling interior material 5 is made of a resin foam material, for example foamed urethane 5b, and is reinforced with glass fibers at appropriate places as required. That is, the ceiling interior material 5 made of foamed urethane 5b is compressed to form a groove 5a, and the compressed portion outside the bottom 5c of the groove 5a is strengthened.
そして必要に応じて、たとえば第５図に示すようにガラ
ス繊維５ｇを混在せしめて硬化しである。 ５ｄは発泡
ウレタン５ｂの室内側を覆う表皮材、５ｅはその発泡ウ
レタン５ｂと表皮材５ｄの間に介在されたガラス繊維シ
ートである。Then, if necessary, for example, as shown in FIG. 5, 5 g of glass fiber is mixed in and hardened. 5d is a skin material covering the indoor side of the urethane foam 5b, and 5e is a glass fiber sheet interposed between the urethane foam 5b and the skin material 5d.
このように構成された天井内装材５の溝５ａは車室天井
の弓状の形状に合せて形成され、その左右両側部分にお
いて、溝５の底部５Ｃの前後の部分で車室天井の両側部
分に接着あるいはアシストクリップなどで止着される。The groove 5a of the ceiling interior material 5 configured in this way is formed to match the bow-like shape of the ceiling of the vehicle interior, and in both left and right portions, the portions before and after the bottom 5C of the groove 5 are formed on both sides of the ceiling of the vehicle interior. It is attached with adhesive or assist clip.
なお、前記実施例では自動車の左右方向に溝を並設した
が、天井内装材を強化したい方向に自由に溝を設けうろ
ことは述べるまでもない。Incidentally, in the above embodiment, the grooves were arranged in parallel in the left-right direction of the automobile, but it goes without saying that the grooves can be freely provided in the direction in which it is desired to strengthen the ceiling interior material.
ｅ、 発明の効果
以上のように本発明に係る天井内装構造によれば、樹脂
発泡材に対し、これを圧縮して平行な多数の溝を形成し
、これら溝の底部を補強して硬化しであるので、天井内
装材全体に剛性が与えられる。その結果、室内側の外観
を損うことなく、必要部分の剛性向上が計れる。e. Effects of the Invention As described above, according to the ceiling interior structure according to the present invention, a large number of parallel grooves are formed by compressing the resin foam material, and the bottoms of these grooves are reinforced and hardened. Therefore, rigidity is given to the entire ceiling interior material. As a result, it is possible to improve the rigidity of necessary areas without damaging the exterior appearance of the interior.
また、本発明によれば、成形時に溝の部分の部分硬化を
施せばよいから製造コストがか＼らない。Furthermore, according to the present invention, only the groove portions can be partially hardened during molding, so manufacturing costs are not increased.
さらにルーフパネルに対し、前記構成の天井内装材を接
着固定することにより、ルーフパネル全体の剛性が向上
し、かつ高度の吸音、遮音性かえられる。Furthermore, by adhesively fixing the ceiling interior material having the above structure to the roof panel, the rigidity of the entire roof panel is improved, and a high degree of sound absorption and sound insulation properties can be obtained.
また、天井内装材表面とルーフパネル間を接着固定する
構造とすることができるため、乗員のヘッドクリアラン
スが充分に確保でき、したがって車高をおさえ込むこと
が可能となる。Furthermore, since the structure can be made such that the surface of the ceiling interior material and the roof panel are adhesively fixed, sufficient head clearance for the occupant can be ensured, thereby making it possible to reduce the vehicle height.
