Abstract
【解決手段】軟質発泡樹脂材料よりなるシートパッド本体2の少なくとも一部に、ビーズ発泡体よりなる別部材3を接合配置し、前記ビーズ発泡体の融着率が50〜90%であることを特徴とする。
【選択図】図1
Description
図1は、本発明の座部シートパッドの一の実施形態を示す縦断面図である。
図中1は座部シートパッドを示し、このシートパッド1には、軟質発泡樹脂材料製のシートパッド本体2と、このシートパッド本体1の、少なくとも一部、図ではシートパッド本体2の下側部に、幅の中央に向けて、厚みを漸減させた、ほぼ楔状の断面形状を有するビーズ発泡体製の、一対の別部材3とを具える。
なお、この融着率は、その成形温度、加熱時間などで制御することができる。
ここで、剥離速度は300mm/minとし、試験片5個の実測値およびその平均値を記録する。
なお、表中の値は、それぞれの試験片5個の平均値である。
