Referring to fig. 1 to 3, in a first embodiment, the sitting and lying dual-purpose chair of the present utility model comprises a support base 1, a chair frame 2, a driven swing link 3 and a telescopic driving swing link 4. The supporting seat 1 supports the chair frame 2 through the driven swing rod 3 and the driving swing rod 4, and the driven swing rod 3 and the driving swing rod 4 are pivoted with the supporting seat 1 and the chair frame 2 in combination with fig. 2 and 3, and the driven swing rod 3 and the driving swing rod 4 can swing synchronously through controlled telescopic change of the driving swing rod 4, so that the toppling posture of the chair frame 2 is correspondingly changed, wherein the state of fig. 2 is a sitting posture state, and the state of fig. 3 is a prone posture state. For convenience of explanation, the X direction in the drawing is the left-to-right direction, the Y direction is the front-to-back direction, and the Z direction is the bottom-to-top direction. As will be described in further detail below.

The support seat 1 comprises a base part 1A, a pivot seat part 1B and a columnar joint part 1C, wherein the columnar joint part 1C is positioned between the base part 1A and the pivot seat part 1B. The pivoting seat 1B can rotate relative to the column-shaped joint 1C, and the scheme for realizing the rotation of the pivoting seat 1B can adopt the existing technology, which is widely used in common office chairs, and is not a gist of the present utility model, so that the description is omitted. The pivot seat part 1B is provided with a pivot lug P pivoted with the driving swing rod 4. The pin joint seat part 1B of the supporting seat 1 is respectively pin-jointed with the driven swing rod 3 and the driving swing rod 4, so that the driven swing rod 3, the driving swing rod 4 and the chair frame 2 can rotate along with the pin joint seat part 1B. In other embodiments, the pivot seat portion 1B may be further designed to move up and down relative to the pillar-shaped joint portion 1C, so that the seat frame 2, the driven swing link 3 and the telescopic driving swing link 4 can move up and down integrally.

The seat frame 2 of the present embodiment includes a seat portion 2A and a backrest portion 2B, and is an integrated seat frame. It should be understood that the seat frame 2 may also be adjusted such that the seat and backrest portions are rotatable relative to each other, and that a telescoping push rod may be mounted between the seat and backrest portions of the seat frame to drive the backrest portion relative to the seat portion. The chair frame 2 can be provided with a massage mechanism (not shown) such as a massage machine core. In another embodiment, the front end of the seat 2A of the chair frame 2 may be pivotally connected with a lower limb rest.

In the first embodiment, the driven swing rods 3 are two groups which are oppositely arranged left and right, each group of driven swing rods 3 comprises a first driven swing rod 3A and a second driven swing rod 3B, and the second driven swing rod 3B is positioned at the rear side of the first driven swing rod 3A. The driving swing rods 4 are positioned at the rear sides of the driven swing rods 3, one driving swing rod 4 is positioned between the two groups of driven swing rods 3 when the front side of the sitting and lying dual-purpose chair is observed, and the distribution mode ensures that the stress distribution of the driven swing rods 3 and the driving swing rods 4 is balanced. The driven swing rod 3 is a curved swing rod, the driven swing rod is gradually bent outwards from bottom to top, the driven swing rod 3 comprises a first pivoting part M1, a connecting part M2 and a second pivoting part M3, the first pivoting part M1 is pivoted on the pivoting seat part 1B, the second pivoting part M3 is pivoted on the chair frame 2, the connecting part M2 is positioned between the first pivoting part M1 and the second pivoting part M3, and the connecting part M2 is inclined outwards from bottom to top. In combination with fig. 1, the size of the outer periphery side of the driven swing rod 3 is gradually enlarged from bottom to top due to the fact that the driven swing rod 3 is gradually bent from bottom to top to the outside, and the size distribution mode can facilitate a user to clean the space below the chair frame 2. As shown in fig. 3 and 4, the driven swing link 3 and the driving swing link 4 are pivoted with the supporting seat 1 and the chair frame 2, and the driven swing link 3 and the driving swing link 4 can swing synchronously through controlled telescopic change of the driving swing link 4, so that the tilting posture of the chair frame 2 is correspondingly changed.
