ステイ付芯材とパツドとを縫製布地の表皮で被覆
し、接続部をフアスナーで塞ぐようにした構造で
ある。
しかしながら、このような中央に孔の開成した
ヘツドレストにあつては、表皮が縫製布地である
ため、縫製工数が多大にかかり、コスト高とな
り、更に、外観品質も安定しない。又、縫製部に
「シワ」、「浮き」等が出やすく品質が一定しない。
このため、特開昭58−203714号公報に示すよう

ｃ 発明が解決しようとする問題点 ところが、表皮の凸条部を挿入するための中芯
の凹溝の成形は、抜き型がインバースになるため
複雑になり、しかも、フイニツシヤとの係合寸法
としては精度の高いことが望まれる。又、パツド
に対して表皮の凸条部は、パツドに固持されてい
ないので、表皮の折れ線の位置が不安定で、フイ

１６内に基部２４がインサートされたクリツプ２
３に干渉しないよう逃げるよう形成されている。
次に、第１図ト，チに示すように、表皮３の中
央凸部８を切断して、他の辺部９と共に、パツド
１５側へ折り返して、パツド１５に固持又は当接
