In the state of use of the invention, 'the shaft (17) of the base (11) is framed by two independent connecting members (2ia) (21b), which are connected (21a) (21b) The chair back (20a) (20b) is attached separately, and each is attached The tilting assembly (3〇) is controlled to form a double seat back shape, and as shown in FIG. 9, the rotating shaft (17) of the base (11) is pivotally connected with a connecting member (21). Further, a backrest (22) extends from the bottom end of the seat back (2〇), and is fixed to the movable end of the connecting member (21) by the back rod (22), thereby forming a form of a single-back chair back, and further As shown in Fig. 10, the shaft (17) of the base (11) is connected to two independent connecting pieces (2la) (2ib), and the central connecting piece (2ia) is connected with a waist rod (23)' And a waist guard (24) is connected to the end of the waist bar (23), thereby forming a seat back structure having a waist-protecting effect. With the structure of the above specific embodiment, the following benefits can be obtained: the seat back (2〇) The pivoting effect is achieved by the connecting piece (21) in cooperation with the rotating shaft (17) of the seat (1), and the function of limiting the tilting angle and restoring is achieved by the woven fabric (31) and the elastic member (32). Further, the rotation adjusting lever (33) 'rotates the adjusting rod (33) to rotate the internal screw (311), and the elastic member (32) can be compressed by the action of the screw (311) to the end of the adjusting rod (33). ) shrinking its activity space To adjust the function of the back angle of the seat back (2〇) to increase its comfort.
