Description

Technical Field

[0001] The utility model relates to the technical field of posture - correcting seats, and particularly relates to an adjustable posture - correcting seat. Background Art

[0002] For sitting posture correction, the incidence of lumbar pain among sitting workers has been increasing year by year. Lumbar pain, lumbar bone soreness, lumbar disc herniation, and muscle soreness in the buttocks and shoulders have become common diseases among people who work sitting. A large part of the cause of these diseases comes from incorrect sitting postures in daily life. To solve this problem and help us correct our sitting postures, sitting - posture - correcting chairs have emerged.

[0003] The posture - correcting seat, through the cooperation of the seat surface and the backrest, and through the ergonomic design of the backrest, helps the user maintain the natural S - shaped curve of the spine, reduces spinal pressure, and the backrest can be tilted at a certain angle to help the user relieve muscle tension.

[0004] The existing posture - correcting seats mainly rely on supporting the spinal part to reduce spinal pressure, so as to help the user achieve the effect of posture correction. However, the backrest part of the existing posture - correcting seats can only achieve angle adjustment. For users of different ages and different heights, the height of the lumbar spine part that needs to be corrected is also different. The backrest support part of the existing posture - correcting seats cannot be well adjusted in height, and can only achieve the height adjustment of the overall seat surface. This leads to a reduction in the correction effect when the user uses it, and even produces side effects, resulting in a further deterioration of the sitting posture. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] Embodiment 1

[0027] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5 , this is the first embodiment of the present utility model. This embodiment provides an adjustable posture-correcting seat, including an L-shaped support plate 2. A support plate 1 is arranged on the outer surface of the L-shaped support plate 2. An adjustment assembly 3 is arranged on the side surface of the support plate 1. The adjustment assembly 3 includes a limit bar 305 fixedly connected to one side of the L-shaped support plate 2 close to the support plate 1. A connecting block 301 is slidably connected to the outer surface of the limit bar 305. One side of the connecting block 301 away from the limit bar 305 is fixedly connected to the outer surface of the support plate 1. A threaded rod 306 is threadedly connected to the inside of the connecting block 301. One end of the threaded rod 306 away from the support plate 1 passes through the L-shaped support plate 2 and is fixedly connected to a rotating block 303. A plurality of limit grooves 302 cooperating with the rotating block 303 are opened on one side of the L-shaped support plate 2 close to the rotating block 303. A sliding groove 304 for the movement of the threaded rod 306 is opened inside the L-shaped support plate 2 and the limit bar 305.

[0028] Specifically, a connecting hole 5 for installation is opened inside the L-shaped support plate 2. A plurality of reinforcing bars 4 are arranged at the turning part of the L-shaped support plate 2 away from the support plate 1. Two raised blocks are arranged on one side of the connecting block 301 close to the limit bar 305. The distance between the two raised blocks is the same as the width of the limit bar 305. The support plate 1 has an oblique angle of 60° to 90°. The cross-section of the support plate 1 part of the L-shaped support plate 2 is in a W shape.

[0029] Further, the chair is installed and fixed through the reserved connection holes 5, and then the rotating block 303 is rotated, thereby driving the threaded rod 306 to disengage from the connecting block 301, so that the rotating block 303 extends out of the limiting groove 302. One end of the threaded rod 306 always remains connected to the connecting block 301. Then, the support plate 1 is moved. The raised blocks provided on the outer surface of the connecting block 301 slide on the surface of the limiting strip 305, while the threaded rod 306 slides in the chute 304. After the support plate 1 is moved to a suitable height, the rotating block 303 is rotated in the reverse direction, so that the threaded rod 306 is fastened to the connecting block 301, and the rotating block 303 is inserted into the corresponding limiting groove 302, thereby realizing the height adjustment of the support plate 1. The cross-section of the part where the L-shaped support plate is connected to the support plate 1 is W-shaped, which improves the strength of the L-shaped connecting plate to cope with the deformation caused by the user leaning on the support plate 1. And a reinforcing strip 4 for improving the strength is provided at the turning part on the side of the L-shaped support plate away from the support plate 1. The support plate 1 has an oblique angle of 60° to 90°, so as to conveniently cope with the sitting postures of different users.

[0030] Working principle: When using the posture-correcting seat, the chair is installed and fixed through the reserved connection holes 5, and then the rotating block 303 is rotated, thereby driving the threaded rod 306 to disengage from the connecting block 301, so that the rotating block 303 extends out of the limiting groove 302. One end of the threaded rod 306 always remains connected to the connecting block 301. Then, the support plate 1 is moved. The raised blocks provided on the outer surface of the connecting block 301 slide on the surface of the limiting strip 305, while the threaded rod 306 slides in the chute 304. After the support plate 1 is moved to a suitable height, the rotating block 303 is rotated in the reverse direction, so that the threaded rod 306 is fastened to the connecting block 301, and the rotating block 303 is inserted into the corresponding limiting groove 302, thereby realizing the height adjustment of the support plate 1. Finally, the height of the support plate 1 of the posture-correcting seat is adjusted to adapt to users of different heights and body types.
