Action, and can be active stability and better support. [0002] • [Prior Art] A conventional seat has a foot pad arrangement that can provide a position for supporting the leg of the foot to enhance the comfort of the sitting seat, and the foot pad can be deployed or folded as needed to facilitate the user to sit on the seat. On the seat. [0003] The conventional foot pad is usually disposed at a position below the front end of the seat and perpendicular to the seat, and is used to pivot the foot pad to be parallel with the seat, for example, US Pat. US6572185, US713471 3, US6402232 Design, but this way will be caused by the lack of length of the mat due to the height of the footrest and the height of the floor. [0004] • It is also known that the foot pad is designed to be interlocked with the back of the chair, and the foot pad can be simultaneously unfolded when the back of the chair is tilted, but this design will cause the foot pad to be unfolded when the seat back is not tilted, and is still applicable. Poor sexuality. [0005] [New content] The purpose of the present invention is to provide an independent control of the deployment of the foot pad, the folding action, and the stability of the position and the better support. Another object of the present invention is to provide a spring-assisted convenience for ease of operation. [0007] Another object of the present invention is to provide an adjustable multi-segment position deployment positioning structure. 10121075#单号A01〇l Page 3 of 20 1013218719-0 M438188 [0008] The seat telescopic pedals The mechanism is disposed under the seat of the seat, and includes a base, an operating rod, two operating rod sets, two telescopic rod sets, and a receiving frame, and the base is fixed under the seat and has two correspondences The bottom surface of the seat is perpendicular and parallel to each other, and the accommodating space between the two joint plates is provided with a guide groove and a plum joint area in the joint plate; and the operating rod is disposed at the base position; The two telescopic rods are disposed in the accommodating space and are connected to the operating rod; and the two telescopic rods are respectively disposed at the positions of the corresponding two engaging plates, and can be unfolded and folded, and the two telescopic rod groups are correspondingly arranged.
