Description
技术领域Technical Field
本发明涉及座椅领域，特别涉及一种坐站调节椅。The invention relates to the field of seats, and in particular to a sit-stand adjustable chair.
背景技术Background Art
座具在现代人学习和工作中广泛使用，对于大多数办公椅或学习椅而言，只具备坐的功能；从生理学角度来说，一个人站久了腿部负荷过重使人易感到劳累；而坐久了人也会感到难受或疲劳，同时还会因为脑供血不足、全身重量压在脊椎底端等引发诸如记忆力减退、头痛头晕、腰椎颈椎等各种疾病，对身体不利。久坐对身体不利已有许多研究和报道，一个人站久了就希望能坐坐，而坐久了又希望能够站站。在久坐的人群中，似乎办公室白领和在校学习的学生坐的时间最长，他们几乎整小时整天地坐着工作或者学习，很难进行姿势的调节，不仅人很容易产生疲劳，而且身体容易受到影响。解决该问题的方法是最好让人的“坐”和“站”能够交替进行。Seats are widely used in modern people's study and work. For most office chairs or study chairs, they only have the function of sitting. From a physiological point of view, if a person stands for a long time, the leg load is too heavy, making people easily tired; and if they sit for a long time, they will feel uncomfortable or tired. At the same time, they will also cause various diseases such as memory loss, headache, dizziness, lumbar spine and cervical spine due to insufficient blood supply to the brain and the weight of the whole body on the bottom of the spine, which is not good for the body. There have been many studies and reports on the harm of sitting for a long time. If a person stands for a long time, he wants to sit, and if he sits for a long time, he wants to stand. Among the sedentary people, it seems that office white-collar workers and students studying in school sit the longest. They sit for almost all hours to work or study, and it is difficult to adjust their posture. Not only are people easily fatigued, but the body is also easily affected. The solution to this problem is to allow people to alternate between "sitting" and "standing".
现有技术中已存在同时具备坐站功能的椅子：如：CN202021173902.2的中国实用新型专利公开了一种“坐站椅”，该坐站椅包括主支撑体和对称设置在主支撑左右两侧的侧支撑体，侧支撑体配置为绕主支撑体转动；沿宽度方向，侧支撑体具有靠近主支撑体的内侧部分以及远离主支撑体的外侧部分；该坐站椅具有坐姿状态与站姿状态；在坐姿状态下：侧支撑体均处于平铺姿态，形成一个供使用者平坐的座位面；站姿状态：侧支撑体相对于主支撑体转动并使侧支撑体上翻至直立姿态，同时侧支撑体的外侧部分升高以迎合使用者就坐或倚靠。该坐站椅通过侧支撑体平铺与上翻的变动实现坐姿与站姿的切换；但是侧支撑体上翻后，座椅的靠背的高度是固定不动的，这就导致了用户在站姿状态下，背部会失去支撑，使用缺乏安全感。其次直接将侧支撑体上翻直立，导致两个侧支撑体集中在中间位置处；使得座椅整体结构视觉上比较突兀，不美观；形变过程中给人的视觉感受不是很好。In the prior art, there are chairs that have both sitting and standing functions: for example, the Chinese utility model patent CN202021173902.2 discloses a "sit-stand chair", which includes a main support body and side supports symmetrically arranged on the left and right sides of the main support, and the side supports are configured to rotate around the main support body; along the width direction, the side supports have an inner part close to the main support body and an outer part away from the main support body; the sit-stand chair has a sitting state and a standing state; in the sitting state: the side supports are all in a flat posture, forming a seat surface for the user to sit flat; in the standing state: the side supports rotate relative to the main support body and turn the side supports up to an upright posture, while the outer part of the side supports rises to cater to the user sitting or leaning. The sit-stand chair achieves the switching between sitting and standing positions by changing the flat and upturned side supports; but after the side supports are turned up, the height of the seat back is fixed, which causes the user's back to lose support in the standing state, and lacks a sense of security when using it. Secondly, the side supports are directly flipped upright, resulting in the two side supports being concentrated in the middle position; this makes the overall structure of the seat visually abrupt and unsightly; and the visual experience given during the deformation process is not very good.
CN201921465494.5的中国实用新型专利公开了一种“座椅变换机构及多用途座椅”，包括底座，设置在底座上的滑轨组件，滑轨组件具有动轨及静轨，以及座支撑件，座支撑件分为第一座与第二座，第二座被配置为连接动轨且总是保持在大致水平状态，第一座相对于第二座铰接；还包括背支撑件，以及连杆。该实用新型首先提供了一种座椅变换机构，其具有两个状态：（1）平坐状态，像普通座椅一样，供人就坐办公。（2）站姿状态；第一座后端抬高，第一座前端向下翻折保持下垂，此时只有第二座呈现支撑人体臀部的状态；使用者可以呈站立状态倚靠在椅座最上方或呈跨越式骑在椅座最上方，符合人们的生理健康。该座椅通过第一座向下翻转保持下垂实现坐姿站姿的变化，使得用户站姿状态下可以坐在第二座上；但是在用户实际使用过程中，站姿状态下，用户的臀部位置相比坐姿状态下更靠前靠上的，但是该座椅仅通过将第二座抬高，且座面的宽度并没有改变，并不会方便用户站姿状态下进行骑跨，使用效果并不会很好。进一步说：该实用新型在实施例中也提到了能够进一步将第二座的前半部分配置为利于使用者骑跨的细长形状，使得第二座在升高后，利于使用者像骑坐在马鞍上一样骑跨在第二座上，第二座能够分别设置为自行车座椅形、椭圆形、细长梯形；但是该结构需要另外在第一座上设置与第二轮廓相吻合的避让槽，且站姿状态下，第一座向下翻转使得避让槽完全露出在外，结构突兀；使得站姿状态下的整体性不好，不美观。The Chinese utility model patent CN201921465494.5 discloses a "seat conversion mechanism and multi-purpose seat", including a base, a slide rail assembly arranged on the base, the slide rail assembly having a moving rail and a static rail, and a seat support member, the seat support member is divided into a first seat and a second seat, the second seat is configured to connect the moving rail and always remain in a roughly horizontal state, and the first seat is hinged relative to the second seat; it also includes a back support member and a connecting rod. The utility model first provides a seat conversion mechanism, which has two states: (1) a flat sitting state, like an ordinary seat, for people to sit and work. (2) a standing state; the rear end of the first seat is raised, and the front end of the first seat is folded down and kept drooping, at this time only the second seat is in a state of supporting the human body's buttocks; the user can lean on the top of the seat in a standing state or ride on the top of the seat in a straddling manner, which is in line with people's physiological health. The seat can change from a sitting position to a standing position by flipping the first seat downward and keeping it drooping, so that the user can sit on the second seat in a standing position; however, in actual use by the user, in the standing position, the user's buttocks are positioned further forward and upward than in the sitting position, but the seat only raises the second seat, and the width of the seat surface does not change, which does not facilitate the user to straddle in the standing position, and the use effect is not very good. Further: the utility model also mentions in the embodiment that the front half of the second seat can be further configured as a slender shape that is convenient for the user to straddle, so that after the second seat is raised, it is convenient for the user to straddle the second seat like sitting on a saddle, and the second seat can be set to a bicycle seat shape, an elliptical shape, and a slender trapezoidal shape respectively; however, the structure needs to set an avoidance groove that matches the second contour on the first seat, and in the standing position, the first seat flips downward so that the avoidance groove is completely exposed, and the structure is abrupt; the integrity in the standing position is poor and unsightly.

采用了上述技术方案的本发明的设计出发点、理念及有益效果是：The design starting point, concept and beneficial effects of the present invention using the above technical solution are:
首先，本发明的坐站调节椅，主支撑体的坐支撑面和站支撑面分别对应在坐姿形态和站姿形态下作为支撑面；坐姿形态下，坐支撑面水平，且坐支撑面、侧支撑体及后支撑座形成整体水平的座位面，方便用户坐姿下就坐。且由坐姿形态转变为站姿形态时，后支撑座抬升，同步的，两个侧支撑体前端下翻，主支撑体后端向上向前翻转使得站支撑面水平，从而使得主支撑体与两个侧支撑体之间形成鞍座状，方便用户站姿乘座；通过侧支撑体及主支撑体共同变形以实现座面变化，整体形变效果好，变形观感更佳；且无论在坐姿形态还是站姿形态下，座支撑组件的结构整体性好，造型美观。继而使得整个座支撑组件和背支撑体形成的座椅整体外观件即为功能件；通过结构变化以在坐姿形态和站姿形态切换。First, in the sit-stand adjustable chair of the present invention, the sitting support surface and the standing support surface of the main support body correspond to the support surface in the sitting posture and the standing posture respectively; in the sitting posture, the sitting support surface is horizontal, and the sitting support surface, the side support body and the rear support seat form an overall horizontal seat surface, which is convenient for users to sit in a sitting posture. When the sitting posture is changed to the standing posture, the rear support seat is lifted, and synchronously, the front ends of the two side support bodies are turned down, and the rear end of the main support body is turned up and forward to make the standing support surface horizontal, so that a saddle shape is formed between the main support body and the two side support bodies, which is convenient for users to sit in a standing posture; the side support body and the main support body are deformed together to realize the seat surface change, the overall deformation effect is good, and the deformation perception is better; and whether in the sitting posture or the standing posture, the seat support assembly has good structural integrity and beautiful shape. Then, the overall appearance of the seat formed by the entire seat support assembly and the back support body is a functional part; through structural changes, the sitting posture and the standing posture can be switched.
其次，主支撑体通过第一导杆和第一导槽的作用能够与后支撑座保持联动，侧支撑体通过第二导杆和第二导槽的作用也能够与后支撑座保持联动；继而由坐姿转为站姿调节时，只需控制后支撑座抬升，主支撑体与侧支撑体将会自行发生联动，从而能够自行变化座面，无需用户再手动调节座面，操作简单，设计巧妙。Secondly, the main support body can maintain linkage with the rear support seat through the action of the first guide rod and the first guide groove, and the side support body can also maintain linkage with the rear support seat through the action of the second guide rod and the second guide groove; then when adjusting from a sitting position to a standing position, it is only necessary to control the lifting of the rear support seat, and the main support body and the side support body will automatically link up, thereby being able to change the seat surface by itself, without the user having to manually adjust the seat surface. The operation is simple and the design is ingenious.
再者，所述连杆装置包括第一连杆机构以及升降支杆，其中后支撑座、第一连杆、第二连杆、底座之间形成四连杆机构，通过该四连杆机构形变以实现后支撑座能够相对底座升降，结构稳定。升降支杆设置在底座与背支撑体的后端，后支撑座升降运动时，升降支杆将相应的绕底座进行转动，且背支撑体上的导引杆相应沿升降滑槽上下滑动以对应后支撑座的升降动作，使得升降运动更加稳定。Furthermore, the linkage device includes a first linkage mechanism and a lifting support rod, wherein a four-link mechanism is formed between the rear support seat, the first linkage rod, the second linkage rod, and the base, and the rear support seat can be lifted relative to the base through deformation of the four-link mechanism, and the structure is stable. The lifting support rod is arranged at the rear end of the base and the back support body, and when the rear support seat is lifted or lowered, the lifting support rod will rotate around the base accordingly, and the guide rod on the back support body will slide up and down along the lifting slot to correspond to the lifting action of the rear support seat, so that the lifting movement is more stable.
另外，所述的后支撑座后端还设有提供背部支撑的背支撑体，从而使得背支撑体将与后支撑座同步向上向前运动，使得用户的背部在坐姿或站姿下始终能够得到支撑；使得人体重心位置不会改变，使用更加舒适。In addition, a back support body for providing back support is also provided at the rear end of the rear support seat, so that the back support body will move upward and forward synchronously with the rear support seat, so that the user's back can always be supported in a sitting or standing position; the center of gravity of the human body will not change, and the use is more comfortable.

Correspondingly, a third support rod 13 and a fourth support rod 14 extending downward are arranged at the bottom of the rear support seat 4, and the third support rod 13 is located in front of the fourth support rod 14. The lower end of the first link 9 is hinged to the first support rod 11, and the upper end of the first link 9 is hinged to the third support rod 13; the lower end of the second link 10 is hinged to the second support rod 12, and the upper end of the second link 10 is hinged to the fourth support rod 14; then a four-link mechanism is formed between the first link 9, the second link 10, the base 2 and the rear support seat 4; the four-link mechanism is deformed to make the rear support seat 4 stably lift and lower relative to the base 2; and during the lifting process of the rear support seat 4, the first link 9 and the second link 10 rotate forward, and the rear support seat 4 moves upward and forward, so that the rear support seat 4 will also move forward during the lifting process, which is more convenient for users to sit in a standing position. In addition, the first link mechanism is mirrored on the left and right sides between the base 2 and the rear support seat 4, making the structure more stable.
此外，如图3-5所示，所述的后支撑座4后端还设有提供用户背部支撑的背支撑体15，背支撑体15与后支撑座4一体成型；从而使得背支撑体15将与后支撑座4同步升降，即上升时，背支撑体15将与后支撑座4一起向上向前运动；使得用户的背部在坐姿或站姿下始终能够得到支撑，使用更加舒适。连杆装置3还包括设置在背支撑体15后端与底座2之间的用于加强稳定性的升降支杆16，升降支杆16的下端铰接在底座2后端；且升降支杆16上端设有竖向的升降滑槽17，所述背支撑体15上对应设有穿设在该升降滑槽17内的导引杆18；继而，所述后支撑座4通过第一连杆机构相对底座2升降过程中，所述的升降支杆16将相应的绕底座2进行转动，且导引杆18沿升降滑槽17上下滑动以对应后支撑座4的升降动作，使得升降运动更加稳定。再者，如图3所示，坐姿形态下，所述的导引杆18将与升降滑槽17下端抵接，能够分散受力，提高结构强度。In addition, as shown in Figs. 3-5, the rear end of the rear support seat 4 is also provided with a back support body 15 for providing back support for the user, and the back support body 15 is integrally formed with the rear support seat 4; so that the back support body 15 will rise and fall synchronously with the rear support seat 4, that is, when rising, the back support body 15 will move upward and forward together with the rear support seat 4; so that the user's back can always be supported in a sitting or standing position, and it is more comfortable to use. The connecting rod device 3 also includes a lifting support rod 16 arranged between the rear end of the back support body 15 and the base 2 for enhancing stability, and the lower end of the lifting support rod 16 is hinged to the rear end of the base 2; and a vertical lifting slot 17 is provided at the upper end of the lifting support rod 16, and a guide rod 18 is correspondingly provided on the back support body 15 and is inserted into the lifting slot 17; then, when the rear support seat 4 is lifted and lowered relative to the base 2 through the first connecting rod mechanism, the lifting support rod 16 will rotate around the base 2 accordingly, and the guide rod 18 slides up and down along the lifting slot 17 to correspond to the lifting action of the rear support seat 4, so that the lifting movement is more stable. Furthermore, as shown in FIG. 3 , in the sitting position, the guide rod 18 will abut against the lower end of the lifting slide slot 17 , which can disperse the force and improve the structural strength.
如图6-9所示，所述的主支撑体5的侧截面呈三角形，座支撑面7和站支撑面8为相邻的两个面。在所述的底座2前端的中间位置处还设有两个间隔的向前上方伸出的连接杆19，所述的主支撑体5的下端两侧分别与连接杆19转动连接，使得主支撑体5能够相对连接杆19转动。所述的后支撑座4的下端设有一固定座21，该固定座21上设有向前水平伸出的一支撑横杆22,所述的支撑横杆22伸出在主支撑体5内；具体而言，如图9所示，所述的主支撑体5由两个壳体5a对接形成，结构简单，连接方便；主支撑体5的后端面为所述的站支撑面8，且该站支撑面8上还具有避让支撑横杆22的避让槽23；且在所述的两个壳体5a的侧面上分别设有第一导槽20，在所述的支撑横杆22上设有水平的第一导杆24，第一导杆24的两端分别穿设在第一导槽20内。如图7所示，在坐姿形态下，所述的坐支撑面7处于水平状态，站支撑面8位于后方且处于斜向后下方倾斜状态；此时，从前往后，所述第一导槽20朝后下方倾斜，第一导杆24位于第一导槽20的前端；由坐姿形态转换站姿状态时，后支撑座4向上向前运动以带动第一导杆24上移；第一导杆24将限制在第一导槽20内并沿第一导槽20移动，从而第一导杆24将对主支撑体5施加一个向上的作用力，从而使得主支撑体5同步相对底座2向上向前转动；如图8所示，站姿形态下，所述的站支撑面8翻转至水平状态，且此时从前往后，所述的第一导槽朝20后上方倾斜，第一导杆24位于第一导槽20的后端。再者，该过程中，只需控制后支撑座4抬升，主支撑体5将会自行发生联动，设计巧妙，无需用户另外操作。As shown in Figs. 6-9, the side section of the main support body 5 is triangular, and the seat support surface 7 and the stand support surface 8 are two adjacent surfaces. Two spaced connecting rods 19 extending forward and upward are also provided at the middle position of the front end of the base 2. The lower ends of the main support body 5 are rotatably connected to the connecting rods 19, so that the main support body 5 can rotate relative to the connecting rods 19. A fixed seat 21 is provided at the lower end of the rear support seat 4, and a support crossbar 22 extending forward horizontally is provided on the fixed seat 21, and the support crossbar 22 extends out of the main support body 5; specifically, as shown in Fig. 9, the main support body 5 is formed by two shells 5a docking, with a simple structure and convenient connection; the rear end surface of the main support body 5 is the stand support surface 8, and the stand support surface 8 is also provided with an avoidance groove 23 for avoiding the support crossbar 22; and first guide grooves 20 are respectively provided on the sides of the two shells 5a, and a horizontal first guide rod 24 is provided on the support crossbar 22, and the two ends of the first guide rod 24 are respectively inserted into the first guide groove 20. As shown in FIG7 , in the sitting posture, the sitting support surface 7 is in a horizontal state, and the standing support surface 8 is located at the rear and is in an inclined state of being obliquely backward and downward; at this time, from front to back, the first guide slot 20 is inclined toward the rear and downward, and the first guide rod 24 is located at the front end of the first guide slot 20; when the sitting posture is converted to the standing posture, the rear support seat 4 moves upward and forward to drive the first guide rod 24 to move upward; the first guide rod 24 will be limited in the first guide slot 20 and move along the first guide slot 20, so that the first guide rod 24 will exert an upward force on the main support body 5, so that the main support body 5 is synchronously rotated upward and forward relative to the base 2; as shown in FIG8 , in the standing posture, the standing support surface 8 is flipped to a horizontal state, and at this time, from front to back, the first guide slot is inclined toward the rear and upward of 20, and the first guide rod 24 is located at the rear end of the first guide slot 20. Furthermore, in this process, it is only necessary to control the rear support seat 4 to lift, and the main support body 5 will automatically be linked, which is a clever design and does not require additional operation by the user.
如图10-11所示，在所述的侧支撑体6与第二连杆10之间还设有使侧支撑体6与后支撑座4之间发生同步运动的联动机构，所述联动机构包括设置在侧支撑体6底部向下伸出的滑座25，在该滑座25上设有第二导槽26，所述的第二导槽26内穿设有一水平的第二导杆27，进一步的说：该第二导杆27依次穿设在第二支杆12和第二连杆10上，且第二导杆27还作为第二支杆12与第二连杆10的转动轴，第二连杆10能够绕该第二导杆27相对底座2转动。其中，在后支撑座4向上抬升过程中，所述第二导杆27将在第二导槽26内相对滑动，从而带动侧支撑体6同步运动；具体的说：如图10所示，在坐姿形态下，从前往后，所述的第二导槽26朝向后上方倾斜，所述第二导杆27位于第二导槽26的后端；由坐姿形态转换站姿形态时，所述第二连杆10向前转动，后支撑座4向上向前运动；所述第二导杆27限制在第二导槽26内并沿第二导槽26移动，从而第二导杆27将对侧支撑体6施加一个向下的力，使得侧支撑体6前端相对后支撑座6向下转动；如图11所示，站姿形态下，从前往后，所述第二导槽26朝后上方倾斜，且倾斜角度更大；此时所述第二导杆27位于该第二导槽26的前端。As shown in Figures 10-11, a linkage mechanism is provided between the side support body 6 and the second connecting rod 10 to enable synchronous movement between the side support body 6 and the rear support seat 4. The linkage mechanism includes a sliding seat 25 extending downward from the bottom of the side support body 6, and a second guide groove 26 is provided on the sliding seat 25. A horizontal second guide rod 27 is passed through the second guide groove 26. Specifically, the second guide rod 27 is sequentially passed through the second support rod 12 and the second connecting rod 10, and the second guide rod 27 also serves as the rotation axis of the second support rod 12 and the second connecting rod 10. The second connecting rod 10 can rotate relative to the base 2 around the second guide rod 27. Among them, during the upward lifting process of the rear support seat 4, the second guide rod 27 will slide relatively in the second guide groove 26, thereby driving the side support body 6 to move synchronously; specifically: as shown in Figure 10, in the sitting posture, from front to back, the second guide groove 26 is inclined toward the rear and upper part, and the second guide rod 27 is located at the rear end of the second guide groove 26; when the sitting posture is converted into the standing posture, the second connecting rod 10 rotates forward and the rear support seat 4 moves upward and forward; the second guide rod 27 is restricted in the second guide groove 26 and moves along the second guide groove 26, so that the second guide rod 27 will apply a downward force to the side support body 6, so that the front end of the side support body 6 rotates downward relative to the rear support seat 6; as shown in Figure 11, in the standing posture, from front to back, the second guide groove 26 is inclined toward the rear and upper part, and the inclination angle is larger; at this time, the second guide rod 27 is located at the front end of the second guide groove 26.
此外，如图3-4所示，在所述的底座2上还转动设有锁定杆28，锁定杆28的上端设有卡钩，在所述的第二连杆10上的对应位置处设有钩槽29；如图3所示，坐姿形态下，锁定杆28转动至直立状态，且卡钩钩接在钩槽29上以限制第二连杆10向上转动；从而能够使座椅锁定在坐姿形态下；解锁时，只需将锁定杆28向外转动离开第二连杆10即可。如图11所示，该坐站调节椅还包括用于驱动连杆装置3形变的驱动组件30，该驱动组件30为常见的气杆或者电动推杆，驱动组件30的一端作用于后支撑座4，驱动组件30的另一端安装在底座2上。In addition, as shown in Fig. 3-4, a locking rod 28 is rotatably provided on the base 2, a hook is provided at the upper end of the locking rod 28, and a hook groove 29 is provided at the corresponding position on the second connecting rod 10; as shown in Fig. 3, in the sitting state, the locking rod 28 is rotated to an upright state, and the hook is hooked on the hook groove 29 to limit the second connecting rod 10 from rotating upward; thereby the seat can be locked in the sitting state; when unlocking, the locking rod 28 only needs to be rotated outward to leave the second connecting rod 10. As shown in Fig. 11, the sit-stand adjustable chair also includes a driving assembly 30 for driving the connecting rod device 3 to deform, and the driving assembly 30 is a common gas rod or electric push rod, one end of the driving assembly 30 acts on the rear support seat 4, and the other end of the driving assembly 30 is installed on the base 2.
综上，本发明坐站调节椅，通过控制连杆装置3形变即可控制座支撑组件1在坐姿形态和站姿形态下切换；并且所述后支撑座4抬升的同时，所述的主支撑体5及侧支撑体6能够发生联动，从而能够自行变化座面，无需用户手动调节座面，操作简单，设计巧妙。再者，在坐姿形态下，坐支撑面7、侧支撑体6及后支撑座4形成整体水平的座位面；在站姿形态下，侧支撑体6向下翻转，所述主支撑体5向上翻转，以使站支撑面8作为用户站姿下的就坐面，且主支撑体5和两个侧支撑体6之间形成鞍座，更方便用户骑座；使得无论在坐姿形态和站姿形态下，座支撑组件1的结构整体好，不突兀，造型美观。且侧支撑体6及主支撑体5同步跟随后支撑座4抬升而使座面自动变形，变形效果更好，变形观感更佳。In summary, the seat-stand adjustable chair of the present invention can control the seat support assembly 1 to switch between the sitting posture and the standing posture by controlling the deformation of the connecting rod device 3; and when the rear support seat 4 is lifted, the main support body 5 and the side support body 6 can be linked, so that the seat surface can be changed automatically, without the need for the user to manually adjust the seat surface, which is simple to operate and ingeniously designed. Furthermore, in the sitting posture, the sitting support surface 7, the side support body 6 and the rear support seat 4 form an overall horizontal seat surface; in the standing posture, the side support body 6 flips downward, and the main support body 5 flips upward, so that the standing support surface 8 is used as the sitting surface of the user in the standing posture, and a saddle is formed between the main support body 5 and the two side support bodies 6, which is more convenient for the user to ride on the seat; so that the structure of the seat support assembly 1 is good as a whole, not abrupt, and beautiful in shape, whether in the sitting posture or the standing posture. And the side support body 6 and the main support body 5 synchronously follow the rear support seat 4 to lift and automatically deform the seat surface, so that the deformation effect is better and the deformation perception is better.
