PROBLEM TO BE SOLVED: To provide a seat cushion that moderates pressure against the back of the knees of the legs of a sitting occupant and achieves weight reduction.SOLUTION: A plate-like knee lower part supporting body, which is formed of synthetic resin foams at a front side of a seat cushion pad, separated from right and left bank parts and made as one singular body, or a plurality of bar-like or a plurality of plate-like knee lower part supporting bodies, which are separated from the right and left bank parts, divided in a longitudinal direction and respectively arranged in a row at predetermined intervals, are provided in a cantilevered state toward the front of the seat cushion pad, so as to allow the knee lower part supporting bodies to be bent while being tilted forward by sitting of a sitting occupant, and below the knee lower part supporting bodies are arranged elastic bodies which are compressed and deformed with respect to a deflection of the knee lower part supporting bodies and have attenuation performance.SELECTED DRAWING: Figure 8
【課題】着座者の足の膝裏部分に対する圧迫を和らげ、軽量化を実現させるシートクッションを提供することである。【解決手段】シートクッションパッド前側に合成樹脂発泡体で成形され、左右の土手部とは分離され一つの単体とした板状の膝下支持体を、または左右の土手部とは分離されかつ前後方向で分割しそれぞれ所定の間隔を空けて列設した複数の棒状又は複数の板状の膝下支持体を、前記シートクッションパッド前方に向かって片持ち梁の状態で設けて前記膝下支持体が着座者の着座により前方に傾倒しながら撓むことを可能とし、かつ前記膝下支持体の下方に前記膝下支持体の撓みに対して圧縮変形して減衰性を有する弾性体を配設することによって課題を解決できた。【選択図】 図8
