Description

【発明の詳細な説明】 本発明は、車輌、家具の座席用或は建材の内装
用等として用いられるところの表装材の接合方法
に関する。
従来、この種表装材では、一定厚みのスポンジ
状クツシヨン芯層１を介し、皮革、合成皮革等の
表皮２と塩ビシート等の裏打材３とを三層に重ね
合せ、それ等を複数対の上下高周波電極棒４，５
による押圧でキルテイング状等に加熱溶着するこ
とにより三者を一体接合することが行なわれてい
る。然し、この表装材では、三者の加熱溶着の為
に、加熱媒体、例えば高周波電極棒等により表皮
側より裏打材側に押圧する際に、該電極棒側部に
接合部周辺の表皮が接触し、該接触部分の表皮が
溶解されまた溶断される危険がある（第１図ａ〜
ｃ参照）。特に第１図ｃに示す如く、側端部附近
の場合には、中央域の場合と異なり、同図右方へ
の引張力が殆んど作用しない為、よりその傾向が
強くなる。しかし乍ら、近来外観をより良くする
ためクツシヨン芯層を年々厚くする傾向にあり、
この問題が助長される。
本発明は、上記の如き欠点を除去し、加熱溶着
時に、加熱媒体に対し接合部周辺の表皮が接触せ
ず、的確且つ安定した溶着作用を行い得る座席等
の表装材を提供することを目的とする。
即ち、本発明に係る表装材の溶着方法に於いて
は、クツシヨン芯層の接合域附近を、他の部分に
比して薄厚乃至完全に取り除いて溶着接合するも
のである。このようにすれば、表皮側から裏打材
側への加熱媒体による押圧に対して、接合部附近
のクツシヨン芯層の膨出変形が殆んど見られず、
従つて接合部附近の表皮と加熱媒体側部との接触
の危険が全くなく、常に的確に溶着し得るもので
ある。
以下、これを第２〜６図で示す実施例に基づい
て説明すれば、次の通りである。
第２図に示す表装材は、クツシヨン芯層１を介
し、表皮２と裏打材３とを三層に重ね合せ、それ
らを高周波溶着で一体接合することにより、表面
側に凹凸状の起伏を呈するように構成したもので
ある。茲で用いられるクツシヨン芯層１はスポン
ジ状のものであり、ウレタンフオーム、ポリエチ
レンフオーム、ラテツクスフオーム等を用いるこ
とができる。また表皮２としては皮革、塩ビシー
ト等を用い、裏打材３としては、塩ビ、ビニロ
ン、ポリエステル、その他適宜の樹脂被膜を用い
ることができる。
溶着施工の形態としては、第２図示の如くキル
テイング状、直線状、網目状、縞模様形状等種々
のものがあるが、いずれの形態を採つてもよい。
この溶着施工の形態に対応して、略板状のクツ
シヨン芯層１の接合予定域部分は、あらかじめ薄
肉となるように成形され、表皮２及び裏打材３と
重ね合わせた際に、空隙部６が生じるように構成
されている（第３図参照）。この薄厚の接合予定
域は、加熱媒体たる高周波電極棒４，５を表皮２
側より裏打材３側へ押圧した際に、表皮２とクツ
シヨン芯層１の表面部分との間に空隙が全く残ら
ず、且つ前記電極棒４の側部に接合予定域附近の
表皮が接触しない範囲の幅及び厚みで成形しなけ
ればならない（第４図参照）接合予定域の幅が不
必要に大きい場合には、表皮２とクツシヨン芯層
１との間に空隙が残り、表皮２の接合目 周辺に
弛みや皺が生じ、表装材として不体裁であると共
に、接合予定域の厚みが大きい場合には、電極棒
４との接触の危険性が残存する為である。
この接合予定域のクツシヨン芯層は、場合によ
つては完全に取り除いてもよい（第５図参照）
が、この場合、クツシヨン芯層１が複数個の独立
クツシヨン芯材から構成されることとなり、その
製造、裏打材上への配設、裏打材と表皮との溶着
のそれぞれに於いて、余分の手間が掛かるので、
単に薄厚として一体成形するのが望ましい。
なお、第６図に示す如く、座席等の背もたれ部
７と座部８とを一体接合する際には、該接合部９
のクツシヨン芯材を完全に取り除き、対の表皮乃
至裏打材同志を直接に加熱溶着せしめることとな

以上の如く構成される、本考案に係る表装材に
依れば、加熱溶着による接合が的確且つ安定的に
行い得るものであつて、中央部或は側端部を問わ
ず、接合目附近の表皮の溶断が回避され、しかも
接合目部分の弛みや皺が全く生ぜず、クツシヨン
性乃至化粧性に優れたものとすることができる。
