To prevent a floor cross member from being deformed by an impact load at the time of a side collision and enable the impact load to be effectively absorbed.SOLUTION: A seat support structure includes: a floor panel; side sills, a pair of front and rear floor cross members connected to the floor panel and extending in a vehicle width direction; and seat brackets connected to the floor cross member and the side sills to support a seat attached to upper surfaces of the seat brackets. The seat brackets each include a support member connected to the floor cross member and to which the seat is attached; and a collapse member interposed between the side sill and the support member to be connected to the side sill and the support member. A collapse portion is formed on the collapse member, and the collapse portion is collapsed and deformed inward in the vehicle width direction when an impact load is applied from the side sill to the collapse member.SELECTED DRAWING: Figure 2
【課題】側面衝突時の衝撃荷重によるフロアクロスメンバの変形を抑制し、且つ衝突荷重を効率良く吸収できるようにする。【解決手段】シート支持構造は、フロアパネルと、サイドシルと、フロアパネルに接合されて車幅方向へ延在する前後一対のフロアクロスメンバと、フロアクロスメンバとサイドシルとに接合されて、上面に取付けられたシートを支持するシートブラケットとを備え、シートブラケットが、フロアクロスメンバに接合されていると共にシートが取付けられる支持部材と、サイドシルと支持部材との間に介在してサイドシルと支持部材とに接合された圧潰部材とを有し、圧潰部材にサイドシルからの衝突荷重を受けた際に車幅方向内側へ圧潰変形する圧潰部が形成されている。【選択図】図2
