Abstract
An improved structure for seat adjusting device mainly comprises a sliding rail and a brake pad used for fixing the sliding rail, wherein the brake pad is arranged as reverse L-shape, and one end of the brake pad is fixed on the sliding rail and the other end of the brake pad is provided with a positioning part. A bolt penetrates through the brake pad so that the positioning part can be locked and fixed on the sliding rail. An abutting part is arranged on one end of the positioning part, and a hooking part and a rubber block are arranged on the other end of the positioning part. A bolt penetrates through an elastic component so that the two ends of the elastic component respectively abut the abutting part and the hooking part of the positioning part, thereby enabling the positioning part to be capable of moving up and down to constitute a seat adjusting device. By means of mounting the symmetrical seat adjusting device on the fixed plate, mounting the fixed plate on a bottom frame of a seat, and fixing the seat on the brake pad, the adjustment of the front position and back position of the seat can be achieved through the sliding of the rail along the fixed plate. Meanwhile, brake positioning can be achieved by means of the self-weight of users.
