Impact absorption structure is provided in side frame element of seat cushion frame, wherein the side frame element is basically of a closed cross-section portion therein, including forward and backward support points therein. In the structure, an opened cross-section area is defined in the closed cross-section by forming a cut-away portion in a lower part of a forward local region of such closed cross-section portion between the forward and backward support points, so that the opened cross-section area is deformable at said cut-away portion by a great load transmitted from a seat back frame thereto, thereby absorbing a corresponding impact.
