Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0025] In the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0027] Referring to the accompanying drawings of the specification, a chair includes a seat body 10 of the chair. A base 20 is provided below the seat body. A fabric is sleeved on the seat body. For better understanding of this structure, the fabric is not drawn in the figure and is similar to that in the prior art and will not be elaborated in detail here. The front side below the seat body is hinged to the base so that the seat body can swing relative to the base. After the base is placed on the ground, it is relatively fixed, and the rear side of the seat body can swing up and down. A buffer device 30 is provided between the rear side of the seat body and the seat body. One end of the buffer device is hinged to the seat body, and the other end of the buffer device is hinged to the base. The buffer device can well give the user a sense of damping and improve the comfort of the chair when it sways. In one use, the buffer device can be an elastic buffer device.

[0028] Preferably, the seat body includes side frames 11 on both sides. The frames can be made by bending rods. An inclined rod 111 is arranged below the frames. A connecting piece 40 is arranged on the inclined rod. The connecting piece is hinged to one end of the base. There is a height difference between the horizontal rods at the front and rear ends of the inclined rod, which is just used to fit the short rod, effectively controlling the overall height.

[0029] Further, the base includes a U-shaped rod formed by bending a rod. The opening of the U-shaped rod faces backward. The connecting piece is hinged to the upper end of the U-shaped rod through a shaft 41. A limiting surface 42 is also arranged on the connecting piece. The limiting surface can be in abutting cooperation with the upper end surface of the U-shaped rod. In use, that is, in the natural state, under the action of the buffer device, when no one is sitting, the upper end surface of the short rod is in abutting cooperation with the limiting surface, ensuring that the chair is in a horizontal state and also preventing the rear end of the seat body from swinging upward. When sitting down, the rear end of the seat body swings downward.

[0030] Still further, the U-shaped rod includes a short rod 21 and a long rod 22 arranged up and down. One end of the short rod is hinged to the connecting piece. The base further includes a U-shaped piece 23 arranged on the long rod. The opening of the U-shaped piece faces downward. The U-shaped piece can buckle outside the frame. The frame can be in abutting cooperation with the bottom surface of the U-shaped piece. In this state, that is, when the upper end surface of the short rod is in abutting cooperation with the limiting surface, one end of the buffer device can be hinged to the U-shaped piece. In this way, through the two restrictions of the limiting surface and the U-shaped piece, the upward swing of the chair can be restricted. At the same time, the U-shaped piece also plays a guiding role. The frame can only swing up and down within the U-shaped piece and will not sway left and right, avoiding danger to the user.

[0031] To improve the applicability of the chair during use, anti-slip sleeves 24 are arranged on the front and rear sides below the long rod.

[0032] Preferably, the buffer device includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod can be inserted into and cooperate with the second connecting rod. The first connecting rod can axially move relative to the second connecting rod. A spring 33 is arranged between the first connecting rod and the second connecting rod. The first connecting rod can be hinged to the seat body. The second connecting rod can be hinged to the base. The first connecting rod can be sleeved inside the second connecting rod. The spring is arranged inside the second connecting rod. The hinge point A of the first connecting rod and the frame is located behind the hinge point B of the second connecting rod and the frame.

[0033] Referring to the accompanying drawings, the seat body further includes a front cross-bar group 12 and a rear cross-bar group 13 located between the two side frames. Both the front cross-bar group and the rear cross-bar group are composed of two rods hinged in the middle. Of course, the upper ends on the same side of the front cross-bar group and the rear cross-bar group can be connected together by a cross-bar 14, so that the front cross-bar group and the rear cross-bar group are composed of two U-shaped rods. A cloth is arranged between the two cross-bars for people to sit on. The lower end of the front cross-bar group is hinged to the lower part of the front side of the frame, and the lower end of the rear cross-bar group is hinged to the lower part of the rear side of the frame. The upper end of the front cross-bar group is hinged to one end of a first connecting piece 51, and the other end of the first connecting piece is hinged to the upper part of the front side of the frame. The connection part of the first connecting piece and the front cross-bar group is located above the self-crossing part of the front cross-bar group. The upper end of the rear cross-bar group is hinged to one end of a second connecting piece 52, and the other end of the second connecting piece is hinged to the upper part of the rear side of the frame. The connection part of the second connecting piece and the rear cross-bar group is located above the self-crossing part of the rear cross-bar group. When folding, the side frames, the buffer device, and the base remain stationary, and the cross-bar moves upward under the action of the two connecting pieces to complete the folding. Since there is also a backrest part above the rear side of the frame, the cross-bar can be prevented from exceeding the backrest part, so that the overall occupied space after folding is reduced.

[0034] In order to reduce the generation of noise and improve the service life, buffer pads 60 are further provided on the first connecting piece and the second connecting piece. The front cross-bar group and the rear cross-bar group can be placed above the buffer pads, or the connection parts of the cross-bar and the two cross-bar groups can be placed above the buffer pads.
