[0005] The above-mentioned seats all maintain the straight state of the user's waist through unique shape design, but none of them can form a direct support for the user's waist, so it can only avoid the problem of pelvic rotation in the forward leaning state, but cannot solve the problem of psoas muscle Strain problem
In addition, these seats only have the effect of correcting the sitting posture, and it is difficult for the user to change the sitting posture to a reclined state, and it is impossible to relax and rest by reclining

Embodiment 1
[0049] 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.
[0050] Such as figure 1 , figure 2 and image 3 As shown, the seat 100 includes a seat board 1 , a waist board 2 , a bottom board 3 , a support rod 4 , a moving mechanism 5 , a linkage mechanism 6 and a limiting mechanism 7 .
[0051] In this embodiment, the seat 100 is in a form similar to a seat cushion. When in use, it needs to be placed on other seats (such as a seat or a stool) before being available for the user to sit on.
[0052] The seat board 1 corresponds to the user's buttocks, and when the user sits, the seat board 1 supports the user's buttocks.
[0053] The waist board 2 corresponds to the user's waist, and when the user s...
Embodiment 2
[0099] In the second embodiment, the same structures as those in the first embodiment are assigned the same symbols and the same descriptions are omitted.
[0100] Figure 8 It is a side view of the seat structure of Embodiment 2 of the present invention.
[0101] Such as Figure 8 As shown, in the seat 200 of the second embodiment, the linkage mechanism 6 is in the form of a connecting rod. That is, the linkage mechanism 6 is a connecting rod, one end of which is hinged on the seat plate 1, and the other end is hinged on the support rod 4. In the linkage mechanism 6, one end hinged to the seat plate 1 is equivalent to a coupling unit, and the end hinged to the support rod 4 is equivalent to a matching unit.
[0102] When the seat board 1 moves forward due to the forward component force, the seat board 1 directly drives the support rod 4 to rotate forward through the linkage mechanism 6; At this time, the support rod 4 also directly drives the seat plate 1 to move backward...
Embodiment 3
[0107] In the third embodiment, the same symbols are assigned to the same structures as those in the first embodiment, and the same descriptions are omitted.
[0108] Figure 9 It is a side view of the seat structure of Embodiment 3 of the present invention.
[0109] Such as Figure 9 As shown, in the seat 300 of the third embodiment, the linkage mechanism 6 is in the form of a push rod. That is, the linkage mechanism 6 is a push rod, the bottom end of which is fixed on the seat plate 1 , and the top end has a push rod pressure wheel 63 which is crimped on the back side of the support rod 4 .
[0110] In the linkage mechanism 6 , the end fixed on the seat plate 1 is equivalent to the coupling unit, and the end which is crimped with the support rod 4 is equivalent to the matching unit.
[0111] When the seat board 1 moves forward due to the forward component force, the seat board 1 drives the linkage mechanism 6 to move forward, and the push rod pressing wheel 63 pushes the ...

Abstract
The invention provides a seat, which is characterized in that the seat comprises a sitting plate, a waist plate, a bottom plate, a supporting rod, a movement mechanism and a linkage mechanism, wherein the sitting plate corresponds to the hip of a user; the waist plate corresponds to the waist of the user; the bottom plate is arranged on the bottom of the sitting plate; the supporting rod is used for supporting the waist plate and is provided with an upper end part combined with the waist plate and a lower end part combined with the bottom plate; the movement mechanism is arranged between the bottom plate and the sitting plate for enabling the sitting plate to move relative to the bottom plate; the linkage mechanism is provided with a combination unit which is at least combined with the sitting plate and a cooperation unit cooperated with the supporting rod. When a user bends forwards, the movement mechanism enables the sitting plate to move forwards relative to the bottom plate, the linkage mechanism drives the supporting rod to forwards rotate through the combination unit and the cooperation unit so as to enable the waist plate to correspondingly generate forward swinging movement; when a user bends backwards, the waist plate generates backward swinging movement, so that the supporting rod backwards rotates, and the linkage mechanism links the movement mechanism through the cooperation unit and the combination unit to enable the sitting plate to backwards move relative to the bottom plate.
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 using the seat, the user generally adopts one of forward leaning, sitting upright and reclining postures. When working at a desk, in order to facilitate placing both hands on the desk, the user usually adopts a forward-leaning posture, that is, the trunk is leaned forward and the lower back is away from 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 smal...
