図２、図３に示すように、座(Ｂ)は、閉結構造とした方形枠状の座フレーム(フレーム)(１)の外周部の上面(表面)に、高張力プラスチック等のネット部材(２)の周辺部を重合した後、この周辺部を、下方へ折り曲げて、座フレーム(１)の外周部の外側面に重合し、さらに座フレーム(１)の下面(裏面)に沿って内方へ折り曲げ、この内向折曲げ部(2a)の下面に、座フレーム(１)とほぼ相似形をなす締付枠(３)を重合し、ボルト(４)をもって、締着して形成されている。
【００１６】
そのため、座フレーム(１)の外周部の下面、および締付枠(３)の複数の対応個所には、それぞれ、ねじ孔(５)と通孔(６)が穿設されている。
【００１７】
ネット部材(２)における前記内向折曲げ部(2a)は、座フレーム(１)の外周部の下面と締付枠(３)の上面との間に、次のようにして挟支保持されている。
【００１８】
座フレーム(１)の外周部(７)は硬質の厚肉部となっておりこの外周部(７)の下面(裏面)には、内側から、上向きの環状逃げ溝(８)、係止用環状溝(９)および受圧用環状溝(10)が設けられている。
【００１９】
内側の環状逃げ溝(８)と中間の係止用環状溝(９)の間の隔壁(11)はやや薄肉となっており、その下端適所には、隔壁(11)の長手方向に対をなして並ぶ多数の上向き切込み(12a)(12a)を設け、隣接する上向き切込み(12a)(12a)の間を、下面が外上方を向く傾斜面とした可撓係止爪(12)としてある。

【００２０】
外側の受圧用環状溝(10)は、緩傾斜の台形断面となっている。
【００２１】
ネット部材(２)の周縁部には、その全長に沿って、座フレーム(１)における厚肉の外周部(７)の外側面および下面に沿って巻回した後、前記係止用環状溝(９)内へ下方から進入しうる断面Ｌ形の係止縁材(13)が止着され、係止縁材(13)の角部における前記可撓係止爪(12)と対応する位置には、係合孔(14)が穿設されている。
【００２２】
ネット部材(２)の幅、従ってその対向する係止縁材(13)(13)間の間隔は、後述のようにネット部材(２)を張設した際、その張力が、一定かつ所望の値となるように定められている。
【００２３】
締付枠(３)の上面は、座フレーム(１)の厚肉の外周部(７)へ下方から嵌合しうる凹溝状となっており、その上面要所には、座フレーム(１)の下面における外側の受圧用環状溝(10)へ、ネット部材(２)を挟支した状態で嵌入しうる断面台形の食い込み突条(15)が形成されている。
【００２４】
締付枠(３)の外周縁には、座フレーム(１)へ取付けた際、座フレーム(１)の下部周縁に重合しうる上向きの保護フランジ(16)が設けられている。
【００２５】
本発明の技術的特徴として、座フレーム(１)の上面(表面)と外側面との交差部に、その稜線の方向を向く凹溝(17)を設け、この凹溝(17)に、軟質材からなる縁材(18)の一部を嵌合し、この縁材(18)の他部でネット部材(２)を外方に押し出すようにしている。
【００２６】
凹溝(17)及び縁材(18)は、座フレーム(１)の全周に設けるのが好ましい。
また、縁材(18)は、例えば軟質ポリウレタン等の、可撓性を有する合成樹脂製の線材により形成するのがよい。線径は、３〜１０ｍｍ程度であるのが好ましい。
【００２７】
ネット部材(２)を座フレーム(１)に取付けるには、まず、ネット部材(２)を、座フレーム(１)の輪郭に応じた形状寸度を有する表面部の周辺に、座フレーム(１)の厚肉外周部(７)の外側面を経て、下方内側へ巻き込んだときに、周縁部が厚肉部(７)の下面の中間の係止用環状溝(９)の付近まで来る形状寸度に裁断するとともに、その周縁にＬ形の係止縁材(３)の内側面を、接着その他適宜の手段で止着しておく。

ついで、座フレーム(１)の下面に締付枠(３)を重合すると、係止縁材(13)は、ネット部材(２)の周縁部とともに、締付枠(３)により上方へ押されて、可撓係止爪(12)を乗り超え、可撓係止片(12)は係合孔(14)に係止して抜け止めする。
【００３０】
またこの際、締付枠(３)の食い込み突条(15)が締付枠(１)の受圧用環状溝(10)内に進入していくため、ネット部材(２)の周辺部は、受圧用環状溝(10)内で強圧される。
【００３１】
しかして、係止用環状溝(９)、および受圧用環状溝(10)は、締付枠(３)の全周に亘り、また係止縁材(13)は、ネット部材(２)の周縁の全周に亘っているから、ネット部材(２)のほぼ全面に亘って、均等な張力が作用し、ネット部材(２)は、体裁よく、かつ強固に張設される。
【００３２】
その後、縁材(18)を、座フレーム(１)の上面とネット部材(２)の下面との間に、座フレーム(１)の内側から順次押し入れて、凹溝(17)の全周に亘って順次係合させ、凹溝(17)から突出した縁材(18)の突出部分により、ネット部材(２)を外方に押し出すことにより、ネット部材(２)にさらに張力を付与することができる。
【００３３】
前記各溝(８)〜(10)は必ずしも環状でなくてもよく、部分的に切られているものでもよい。

受圧用環状溝(10)を締付枠(３)の上面に、また食い込み突条(15)を、座フレーム(１)の外周部(７)の下面に設けてもよい。
【００３５】
さらに、図８に示すように、凹溝(17)の上方に外向きの突条(19)を設け、これと締付枠(３)の保護フランジ(16)との間に、縁材(18)とその外周を取り巻いて垂下するネット部材(２)の垂下部分とを挟むようにすると、縁材(18)の外れや移動を阻止することができるだけでなく、ネット部材(２)の伸びをも防止することができる。
【００３６】
【発明の効果】
各請求項に記載の発明の効果は、次の如くである。
