Abstract
Description
図1~7に基づいて第1実施形態に係るシートパッド10について説明する。このシートパッド10は、例として、自動車の座席の背もたれ部を構成するバックパッドである。シートパッド10は、軟質ポリウレタンフォームの発泡成形体からなるパッド本体12と、三次元網目構造体からなる通気性クッション体14とを備えてなる。
図8は、第2実施形態に係るシートパッド10Aを示したものである。この実施形態では、通気性クッション体14をメイン部16の中段部16Bに設ける代わりに、メイン部16の下段部16Cに設けた点が、第1実施形態とは異なる。
図9は、第3実施形態に係るシートパッド10Bを示したものである。この実施形態では、通気性クッション体14をメイン部16の中段部16Bに設ける代わりに、メイン部16の上段部16Aに設けた点が、第1実施形態とは異なる。
図10は、第4実施形態に係るシートパッド10Cを示したものである。この実施形態では、通気性クッション体14をメイン部16の中段部16Bに設ける代わりに、左右のサイド部18,18に設けた点が、第1実施形態とは異なる。
図11は、第5実施形態に係るシートパッド10Dを示したものである。この実施形態では、通気性クッション体14をメイン部16の中段部16Bだけでなく、下段部16C、上段部16A及び左右のサイド部18,18にも設けた点で、第1実施形態とは異なる。
図12及び図13は、第6実施形態に係るシートパッド10Eを示したものである。この実施形態では、通気性クッション体14をパッド本体12の発泡成形により積層一体化する代わりに、パッド本体12の発泡成形後に通気性クッション体14を設置する点で、上述した第1実施形態とは異なる。
以上の実施形態では、背もたれ部としてのバックパッドの場合について説明したが、本発明は、着座者である乗員の臀部を支持するためのシートクッションパッドにも同様に適用することができる。
