The invention discloses an automobile seat cushion framework with a descending prevention function. The automobile seat cushion framework comprises two side plates, a pair of front connecting rods and a pair of rear connecting rods, wherein the front and rear parts of each side plate are articulated with an upper sliding rail by virtue of one front connecting rod and one rear connecting rod; a descending prevention rod is connected between the two side plates; the outer side edge of each front connecting rod is provided with a flange which is protruded outwards; when the automobile seat cushion framework descends to the bottommost position, the descending prevention rod is withstood by the flanges; when the whole automobile seat cushion framework is collided, the front connecting rods can not rotate around the articulation points of the front connecting rods and the upper sliding rail, and a fixed frame body is formed between the side plates, the front and rear connecting rods and a lower sliding rail. Compared with the prior art, the automobile seat cushion framework has the advantages of being capable of reducing the excessive descending amount caused by clearances between the descending prevention rod and the front connecting rods and the deformation of the side plates, effectively catering to the stress direction of the descending prevention rod, and providing stable support so as to improve the safety performance of a seat.
