Embodiment 1

[0096] Embodiment 1: the present invention provides a chair unit at first, such as Figure 1-10 shown, including:

[0097] Seat support assembly 1, said seat support assembly 1 includes lift air rod 2, and the lower end of lift air rod 2 is plugged with support foot 3 with roller 4 at the bottom.

[0098] The base 5 above the ground is supported by the seat support assembly 1, and the base 5 is plugged with the upper end of the lifting air rod 2, and the height of the base 5 from the ground can be controlled by the lifting air rod 2. In this embodiment The height is set to 360-550cm; 400cm is the suitable height for most people.

[0099] The slide rail assembly 6 standing on the base 5, the slide rail assembly 6 has a moving rail 7 and a static rail 8 that are slidably matched with each other, wherein the static rail 8 and the base 5 are fixed by welding or connected by fasteners.

[0100] The seat support member 9 arranged on the front side of the slide rail assembly 6; the...

Embodiment 2

[0119] Embodiment 2: as Figure 11-16 , Shown in 20-23, 33-36, differ from embodiment 1 in that, the present embodiment is not provided with lever arm 63, but adopts four-bar linkage to guide.

[0120] Specifically, this embodiment also includes a first connecting rod 64 and a second connecting rod 65, one end of the first connecting rod 64 is hinged to the middle seat 11, the other end of the first connecting rod 64 is connected to one end of the second connecting rod 65 Hinged, the other end of the second connecting rod 65 is hinged with the side seat 10, the first connecting rod 64, the second connecting rod 65, the side seat 10 and the middle seat 11 form a four-bar linkage mechanism, and the guide shaft 61 is arranged at the second On a connecting rod 64.

[0121] In the four-bar linkage mechanism, the middle seat 11 is stationary, and when the guide shaft 61 is guided by the chute 60, the first link 64 and the second link 65 are linked, thereby driving the side seat 10 ...

Embodiment 3

[0125] Embodiment 3: as Figure 16 , 37 As shown in -42, the difference from Embodiments 1 and 2 is that the base 5 of this embodiment adopts a tilting chassis, so that not only the initial height of the base 5 can be adjusted normally, but also it has a tilting position when sitting flat. function to make sitting more comfortable.

[0126] Specifically, the base 5 includes a seat body 31 and a seesaw 32 that is rotatably connected to the seat body 31. The static rail 8 is fixedly connected to the seesaw 32. The upper end of the lifting air rod 2 is connected to the seat. The body 31 is plugged and fitted, and a return spring 68 is provided between the seesaw 32 and the seat body 31 .

[0127] A safety lock control mechanism is provided between the base 5 and the middle seat 11. The safety lock control mechanism includes a lock plate 69, a mounting seat 70, a slide pin 72, a torsion spring 73 and a lock pin 74. The lock plate 69 is fixedly arranged on the seat. On the body ...

Abstract

The invention discloses a chair unit and a chair. The chair unit comprises a base and a sliding rail assembly with a movable rail and a static rail, and the static rail is fixedly connected with the base; a seat supporting piece comprises a middle seat and a side seat, wherein the middle seat is configured to be always kept in an approximately horizontal state or form an acute angle with the horizontal plane, and the middle seat and the movable rail are relatively fixed; the side seat is hinged with the middle seat; a back supporting piece is connected with the movable rail and moves up and down along with the movable rail, and a linkage mechanism responds to lifting movement of the middle seat and acts on the side seat to enable the side seat to turn over relative to the middle seat. Thechair unit provided by the invention has two states, namely a flat sitting state and a standing posture state, and a chair conversion mechanism can freely convert between the two states and can convert only by sliding fit of the sliding rail assembly; compared with the prior art, the structure is simple, operation is easy and convenient, and the experience feeling of a user is good. The chair unit disclosed by the invention is convenient and rapid to switch between sitting and standing and can be widely applied to occasions such as offices and families.
