PROBLEM TO BE SOLVED: To restrain and protect a thigh part of an occupant by surely operating without delaying in side collision occurrence time by an inexpensive and simple constitution.SOLUTION: Left-right side support parts 3a and 3b for forming left-right side surfaces are fixed to a seat frame 2a, a seat pan member 5 is supported on the seat frame 2a by energizing upward by a plurality of coil springs 4, a load transmission member 8, which moves by interlocking with an addition of a load to a locker member 7 caused by a side collision, is extendedly arranged under a seat cushion 2 from the side surface of the locker member 7, and the seat pan member 5 and the load transmission member 8 are connected by a plurality of connection members 10. The seat pan member 5 is moved downward against energization of the coil springs 4 by the movement of the load transmission member 8 in the side collision, the seat pan member 5 is relatively sunk in to both side support parts 3a and 3b, and a thigh part H of an occupant is restrained from both sides by both side support parts 3a and 3b.
【課題】安価かつ簡単な構成により、側突発生時に遅れることなく確実に作動して乗員の大腿部を拘束して保護できるようにする。【解決手段】シートフレーム2aに左右の側面を成す左右のサイドサポート部3a,3bを固定し、シートフレーム2a上に複数個のコイルばね4によりシートパン部材5を上方に付勢して支持し、側突に伴うロッカ部材7に対する荷重の付加に連動して移動する荷重伝達部材8を、ロッカ部材7の側面からシートクッション2の下方に延出して配設し、シートパン部材5と荷重伝達部材8とを複数の連結部材10により連結する。そして、側突時に荷重伝達部材8の移動によりシートパン部材5をコイルばね4の付勢に抗して下方に移動させて両サイドサポート部3a,3bに対してシートパン部材5を相対的に沈み込ませ、両サイドサポート部3a,3bにより乗員の大腿部Hを両側から拘束する。【選択図】図1
