To disperse and absorb with good efficiency an impact load at the time of side collision.SOLUTION: A side collision attitude control device has an under air cover 17r, an under cover 11, and a control unit 21. The under air bag 17r is located at a lower part of a floor panel 7 of an own vehicle, and the under cover 11 covers an undersurface of the under air bag 17r. In both sides of the under cover 11 in a width direction, a reinforcement 13r side is joined with weaker joining force than a side sill 4r side with respect to a side sill 4r and a reinforcement 13r which are provided in a vehicle width direction of the floor panel 7. The control unit 21 determines a time (collision prediction time) |ΔT| when an approaching vehicle S, which approaches the own vehicle M from the side, collides with the own vehicle, and immediately before reaching this collision prediction time |ΔT|, a part of the under cover 11, which is joined with weak joining force, is separated to inflate and expand the under air bag 17r.SELECTED DRAWING: Figure 3

    【課題】側面衝突時の衝撃荷重を分散させて効率良く吸収させる。【解決手段】側突時姿勢制御装置は、アンダエアバッグ17rとアンダカバー11と制御ユニット21を有する。アンダエアバッグ17rは自車両のフロアパネル7の下部に配設され、アンダカバー11はアンダエアバッグ17rの下面を覆う。又アンダカバー11の幅方向両側が、フロアパネル7の車幅方向に設けられたサイドシル4rとリンフォース13rに対し、リンフォース13r側がサイドシル4r側よりも弱い接合力で接合されている。制御ユニット21は、自車両Mに対して側方から接近する接近車両Sが衝突する時間(衝突予測時間)|ΔT|を求め、この衝突予測時間|ΔT|に達する直前で、アンダカバー11の弱い接合力で接合されている部位を乖離してアンダエアバッグ17rを膨張展開させる。【選択図】図3
