PROBLEM TO BE SOLVED: To provide a seat cushion frame of a seat for an automobile, effectively catching to inhibit the forward movement without giving any unreasonable shock to an occupant by receiving the load caused by the occupant's forward movement by stages at the time of a front collision. SOLUTION: Right and left side frames 10, 9, a front cross member 11 and a rear cross member 12 constitute a frame quadrangular in a plan view. The front cross member 11 is formed by bending a substantially rectangular metal plate material, and the cross sectional shape along a longitudinal cutting line has a top face part 13 having a gently curved to be gradually lowered with a downward gradient from the front side to the rear, a front part 17 hanging down with a gradient from the front end of the top face part 13 through a front end bent part 14 toward the rear and a rear end part 20 extended forward from the rear end of the top face part 13. The respective both end parts of the top face part 13, the front part 17 and the rear end part 20 are at least partly fixed to the right and left side frames 10, 9. COPYRIGHT: (C)2006,JPO&NCIPI
