Problems solved by technology

However, angle adjustment mechanisms such as recliners usually need to rely on a locking mechanism to achieve angle locking, and users need to use control parts such as handles or control levers to unlock the locking mechanism to perform angle adjustment, which is cumbersome to operate; If the control parts are installed at the front side of the seat where the user's hands are easy to touch, it is easy to bump the user. If it is installed at the position below or behind the seat that will not bump the user, the user needs to bend down or It can only be operated by twisting the waist, so this kind of seat is also very inconvenient to use

Embodiment 1

[0044] figure 1 It is a structural schematic diagram of a seat in Embodiment 1 of the present invention, figure 2 It is a schematic diagram of the side view structure of the seat in Embodiment 1 of the present invention, image 3 It is a schematic diagram of the exploded structure of the seat in Embodiment 1 of the present invention.

[0045] Such as figure 1 , figure 2 and image 3 As shown, the seat 100 according to the first embodiment of the present invention includes a seat board 10 , a waist board 20 , a support member 30 , a movement path control assembly 40 and a seat surface 50 .

[0046] The seat board 10 is plate-shaped, corresponding to the user's buttocks, and supports the user's buttocks during use. In addition, the lower surface of the seat board 10 is a plane, and the seat board 10 can be placed on other seats with supporting legs during use, so as to be used in conjunction with such seats.

[0047] The waist board 20 corresponds to the waist of the use...

Embodiment 2

[0112] In the second embodiment, the same structures as those in the first embodiment are assigned the same symbols and the same descriptions are omitted.

[0113] Figure 14 It is a structural schematic diagram of a seat in Embodiment 2 of the present invention. exist Figure 14 In , some detailed structures are omitted in order to briefly show the overall structure of the seat.

[0114] Such as Figure 14 As shown, the same as the first embodiment, the seat 200 of this embodiment also has a seat board 10, a waist board 20, a support member 30, a movement path control assembly 40 and a seat surface (not shown in the figure).

[0115] The difference from Embodiment 1 is that the support member 30 of this embodiment is rotatably mounted on the waist board 20, while the movement path control assembly 40 is arranged on the seat board 10, and correspondingly, the support cross bar portion 31 is also located on the support member The lower end of 30 is combined with the seat bo...

Embodiment 3

[0119] In the third embodiment, the same structures as those in the first embodiment are assigned the same symbols and the same explanations are omitted.

[0120] Figure 15 It is a structural schematic diagram of the path adjustment member and the cover member in Embodiment 3 of the present invention.

[0121] Such as Figure 15 As shown, the difference between the seat in this embodiment and the seat 100 in Embodiment 1 is that the accommodating portion 421 of the path adjusting member 42 is a closed ring. That is to say, the first free end 4211 and the second free end 4212 are connected to each other as a whole.

[0122] The above-mentioned structure of this embodiment can also realize the same functions as the cooperation between the pressing piece and the receiving part and the mutual cooperation of the blocks as in the first embodiment, but compared with the first embodiment, since the first free end of the first block 424 is provided 4211 does not exist, and the pres...

Abstract

The invention provides a seat device. The seat device comprises a seat plate, a waist plate, a support part and a movement path control assembly, wherein the seat plate corresponds to hips of a user;the waist plate corresponds to the waist of the user, and is rotationally arranged on the seat plate; the support plate is used for supporting the waist plate, and stabilizing the waist plate onto a position in a working state corresponding to the sitting gesture of the user in the working state, or stabilizing the waist plate onto a position in a rest state corresponding to the sitting gesture ofthe user in the rest state; the support plate is provided with a support transverse rod part; the movement path control assembly is used for controlling the support transverse rod part to move in a movement path formed among the position in the working state, the position in the rest state, and an adjusting position between the position in the working state and the position in the rest state.

Description

technical field [0001] The invention belongs to the field of daily necessities and relates to a seat. Background technique [0002] Seats such as seats and stools are an indispensable part in people's daily life and work. Wherein, the seat has a backrest, which can support the back of the human body when the user leans back, so that the user feels comfortable, so it is widely used. [0003] When working, in order to place both hands on the desk conveniently, the user usually adopts a leaning forward or sitting posture, that is, the trunk leans forward or stands upright, and the lower back leaves the backrest of the seat. At this time, the backrest cannot fit the lower back, so it cannot support the lower back. The weight of the upper body of the user is transmitted to the pelvis through the spine, causing the pelvis to rotate backward around the ischium, resulting in a smaller lumbar protrusion curvature. The posterior opening angle between the lumbar vertebrae increases, ...
