The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0026] Below, reference is made to Figures 1-3 Describe the ergonomic seat 100 according to the embodiment of the present utility model.
[0027] As Figures 1-3 shown, the ergonomic seat 100 according to the embodiment of the present utility model includes: a seat cushion assembly 1, a backrest assembly 2, and a lumbar support assembly 3.
[0028] Specifically, the seat cushion assembly 1 includes: a seat cushion frame 11 and a seat cushion body 12 that wraps the seat cushion frame 11. The backrest assembly 2 includes: a backrest bracket 21. The backrest bracket 21 is connected to the seat cushion frame 11. One end of the lumbar support assembly 3 is rotatably connected to the backrest bracket 21, and the other end of the lumbar support assembly 3 is connected to the seat cushion frame 11. The lumbar support assembly 3 includes: a lumbar support bracket 31 and a lumbar support body 32. The lumbar support bracket 31 extends along an arc that protrudes in a direction away from the backrest bracket 21 in the height direction of the backrest bracket 21, and the lumbar support body 32 is movably provided on the lumbar support bracket 31.
[0029] That is to say, the backrest bracket 21 is connected to the seat cushion frame 11, and the seat cushion frame 11 is wrapped with the seat cushion body 12. As shown in the figure, the upper end of the lumbar support assembly 3 is rotatably connected to the backrest bracket 21, and the lower end of the lumbar support assembly 3 is connected to the seat cushion frame 11. In the up and down direction, the lumbar support bracket 31 extends along an arc that protrudes in a direction away from the backrest bracket 21 (such as Figure 2 the right direction shown in the figure), and the lumbar support body 32 is movable on the lumbar support bracket 31. Thus, the structural design of the ergonomic seat 100 is simple and ingenious, and can well reduce the discomfort of the human body.
[0030] The purpose of the design of the ergonomic seat 100 is to provide the best sitting posture support, reduce the pressure and discomfort on the body caused by sitting for a long time. For traditional ergonomic chairs, when reclining, the position of the lumbar support can be adjusted to support the waist. The lumbar pillow can be moved and rotated at a small angle to adapt to the waists of different people. Usually, when reclining, the position of the lumbar support needs to be adjusted again, but the adjustment of the reclining posture is not convenient. Therefore, for the ergonomic seat 100 of the embodiment of the present utility model, when the user sits on the seat cushion assembly 1 in a standard sitting posture, as Figure 2 shown, the lumbar support assembly 3 is in the initial position to support the human waist. When the user reclines, as Figure 3 shown, the lumbar support assembly 3 rotates and moves downward along with the position of the human waist to the support position, ensuring that it always fits the human waist.
[0031] For the ergonomic seat 100 according to the embodiment of the present utility model, by movably arranging the lumbar support body 32 on the lumbar support bracket 31, it can automatically rotate and move with the force exerted when the user reclines, so as to ensure that the lumbar support assembly 3 can always provide continuous support for the waist, which helps to maintain the natural curve of the spine, reduce the pressure on the spine, significantly relieve the fatigue of the lumbar muscles, and enable the seat to adapt to the body shapes and sitting posture habits of different users.
[0032] In some embodiments, the backrest assembly 2 further includes a backrest body, and the backrest body is wrapped outside the backrest bracket 21 to improve the comfort for the user.
[0033] Furthermore, the lumbar support assembly 3 further includes a first connecting member 33. One end of the first connecting member 33 is connected to the seat cushion frame 11, and the other end of the first connecting member 33 is rotatably connected to one end of the lumbar support bracket 31. The lumbar support bracket 31 can rotate relative to the seat cushion frame 11, thereby realizing the angle adjustment of the lumbar support assembly 3. In this way, the user can adjust the position and angle of the lumbar support according to personal body shape and sitting posture needs to obtain the best support effect and relieve the fatigue of the lumbar muscles.
[0034] Even further, the lumbar support assembly 3 further includes: a second connecting member 34. One end of the second connecting member 34 is connected to the other end of the lumbar support bracket 31, and the other end of the second connecting member 34 is rotatably connected to the backrest bracket 21. The lumbar support bracket 31 can rotate relative to the backrest bracket 21, thereby realizing the angle adjustment of the lumbar support assembly 3. In this way, through the cooperation of the lumbar support assembly 3 with the first connecting member 33 and the second connecting member 34, the best angle adjustment of the lumbar support assembly 3 is realized, and the fatigue of the lumbar muscles is significantly relieved. Specifically, the length dimension of the second connecting member 34 is preferably 65 mm, the width dimension of the second connecting member 34 is preferably 40 mm, and the second connecting member 34 is a plastic part.
[0035] In some embodiments of the present utility model, the first connecting member 33 is formed with a first connecting hole, and the lumbar support bracket 31 is formed with a second connecting hole. The first connecting member 33 and the lumbar support bracket 31 are relatively rotatable by the first shaft 4 passing through the first connecting hole and the second connecting hole. In this way, the relative rotation of the lumbar support assembly 3 around the seat cushion assembly 1 is realized; the second connecting member 34 is formed with a third connecting hole, and the backrest bracket 21 is formed with a fourth connecting hole. The second connecting member 34 and the backrest bracket 21 are relatively rotatable by the second shaft passing through the third connecting hole and the fourth connecting hole. In this way, the relative rotation of the lumbar support assembly 3 around the backrest bracket 21 is realized. Thus, the lumbar support can adapt to various sitting postures, provide the best lumbar support, reduce the pressure on the waist during long-term sitting, and help maintain a healthy sitting posture, and the overall connection structure is simple and ingeniously designed.
[0036] Specifically, one end of the lumbar support bracket 31 is formed with a connecting portion 311, the connecting portion 311 extends along the height direction of the backrest bracket 21, and the second connecting hole is formed on the connecting portion 311. Thus, the relative rotational connection between the lumbar support bracket 31 and the backrest bracket 21 is realized, and the connection stability and flexibility between the lumbar support assembly 3 and the seat cushion frame 11 are increased.
[0037] In some embodiments of the present utility model, the lumbar support bracket 31 is formed with a first adjusting portion 312, and the lumbar support body 32 is formed with a second adjusting portion. The lumbar support body 32 adjusts the relative position with the lumbar support bracket 31 through the cooperation of the first adjusting portion 312 and the second adjusting portion. Specifically, the second adjusting portion is formed as an adjusting groove, and the first adjusting portion 312 is formed as a plurality of limiting protrusions. The adjusting groove and the plurality of limiting protrusions cooperate to adjust the relative position between the lumbar support bracket 31 and the lumbar support body 32. Thus, the relative movement between the lumbar support bracket 31 and the lumbar support body 32 is realized, adapting to people of different heights.
[0038] Furthermore, a slide rail is formed on the lumbar support bracket 31, and a slide groove is formed on the lumbar support body 32. The slide rail and the slide groove cooperate to define the moving direction of the lumbar support body 32 on the lumbar support bracket 31. The overall structure is simple and firm, facilitating assembly.
[0039] In some embodiments of the present utility model, the lumbar support assembly 3 further includes: an elastic member, one end of the elastic member is connected to the lumbar support body 32, and the other end of the elastic member is connected to the backrest bracket 21. It can be understood that when the user sits on the seat cushion assembly 1 in a standard sitting posture, the lumbar support assembly 3 is in the initial position to provide support for the human waist. At this time, the elastic member is in the initial state. When the user leans backward, the lumbar support assembly 3 rotates and moves downward to the support position along with the position of the human waist, ensuring that it is always in contact with the human waist. At this time, the elastic member is in a stretched state. The elastic member has a force to return the lumbar support body 32 to the initial position. When the user returns from the backward-leaning state to the standard sitting posture, the lumbar support body 32 is pulled back to the initial position by the elastic member.
[0040] In some embodiments of the present utility model, the cross-sectional area of the lumbar support bracket 31 gradually decreases in the direction away from the seat cushion assembly 1. Thereby, the comfort of the ergonomic seat 100 is improved, and the weight of the ergonomic seat 100 is reduced. Specifically, the width dimension of the upper end of the lumbar support bracket 31 is preferably 66 mm, and the width dimension of the lower end is preferably 140 mm.
[0041] Preferably, the lumbar support bracket 31 is formed as a metal part.
[0042] In some embodiments of the present utility model, the lumbar support body 32 includes a frame and a mesh. A card slot is formed along the periphery of the frame. The mesh covers the frame and is connected to the frame by being clamped in the card slot by a card strip. Thereby, the connection method is simple, and it has good air permeability, high comfort, long service life, and is easy to clean and maintain. Specifically, the length dimension of the lumbar support body 32 is preferably 385 mm, and the width dimension is preferably 240 mm.
