Abstract

The invention relates to a fine adjustment mechanism of a supporting leg bracket on a chair. The supporting leg bracket is connected with the chair. The fine adjustment mechanism comprises a first rod piece, a second rod piece, a third rod piece and a fourth rod piece; one end of each of the first rod piece and the second rod piece is rotatably connected with the chair; one end of each of the third rod piece and the fourth rod piece is rotatably connected with the first rod piece; the other ends of the third rod piece and the fourth rod piece are rotatably connected with the supporting leg bracket; the second rod piece is rotatably connected with the fourth rod piece; an adjusting hole is formed in the first rod piece; and one end of the third rod piece rotates and slides relative to the first rod piece through the adjusting hole. According to the fine adjustment mechanism greatly, the comfortability of double legs, placing on the supporting leg bracket, of a user, is greatly improved, and the whole structure is simple and reasonable.

Description

technical field [0001] The invention relates to a seat, in particular to a fine-tuning mechanism for a leg support on the seat. Background technique [0002] The massage chair achieves the purpose of soothing and health care by massaging the whole body or part of the human body. A massage chair generally includes a base, a seat body arranged on the base, and a leg support connected to the seat body. A drive mechanism is generally provided between the outrigger bracket and the seat body to adjust the angle between the two, so as to achieve the desired use angle of the user. However, once the angle between the outrigger bracket and the seat body is adjusted by the driving mechanism, the two will be in a relatively fixed state. At this time, if the user still feels uncomfortable, the adjustment can no longer be made to ensure the comfort of use. decline. Contents of the invention [0003] The purpose of the present invention is to provide a fine-tuning mechanism for the ou...
