A waist-protecting and posture-correcting chair

Technical Field

The utility model relates to the technical field of seats, in particular to a waist protection and posture correction seat.

Background Art

Ergonomic chairs are a new type of environmentally friendly and healthy chairs. They are widely used in homes, offices, leisure and entertainment venues. Ergonomic chairs conform to the principles of ergonomics, so they can fit the needs of the human body well and help people sit healthily and comfortably.

First embodiment:

As shown in Figures 1 to 5, a lumbar protection and posture correction chair is disclosed, the chair comprises a lumbar support part 1, a connecting part 2 and a hip-leg part 3 which are connected in sequence, the lumbar support part 1 comprises a lumbar support part 11 which is symmetrically arranged along a vertical plane where the midline of the human body is located, when the lumbar support part 11 is observed from a side angle, the front end of the lumbar support part 11 is bent toward a side close to the human waist, when the lumbar support part 1 is observed from a top angle, the side surface of the lumbar support part 11 is bent toward a side close to the human waist to embrace and support the human waist, and a first protrusion 12 is further arranged in the middle of the lumbar support part 1, the first protrusion 12 is engaged with the human spine line to achieve lumbar posture correction.

According to the standard sitting posture of the human body, the trunk is at right angles to the thigh, the thigh is at right angles to the calf, and the axis of the trunk and the axis of the thigh are in the same vertical plane. As shown in Figures 4 and 5, specifically, the upper end of the waist support portion 11 is bent toward the side away from the human waist, and the lower end of the waist support portion 11 is bent toward the side away from the human waist, so that the waist support portion 11 as a whole is bent toward the side close to the human waist, and the front end surface of the waist support portion 1 fits the rear curve of the human waist to ensure that the upper body of the human body is in a vertical state. At the same time, the two sides of the waist support portion 1 embrace and support the human waist, and the surface of the waist support portion 1 fits the side curve of the human waist to locate the waist position, and the first protrusion 12 can be stuck into the human spine line to prevent scoliosis.

As shown in Figures 4 and 6, further, the hip and leg part 3 includes a support part 31 symmetrically arranged along the vertical plane where the midline of the human body is located. When the support part 31 is observed from a side view, the rear end of the support part 31 is bent toward the side close to the human buttocks, and the front end of the support part 31 is bent toward the side away from the human thigh. When the support part 31 is observed from a front view, the side of the support part 31 is bent toward the side close to the human thigh to embrace and support the human thigh. A third protrusion 32 is also arranged in the middle of the hip and leg part 3, and the third protrusion 32 is inserted between the human thighs to achieve leg posture correction.

Specifically, the upper surface of the hip-leg portion 3 fits the lower curve of the human thigh and buttocks to ensure that the thigh is in a horizontal state. At the same time, the hip-leg portion 3 embraces and supports the human thigh on both sides, and the upper surface of the hip-leg portion 3 fits the side curve of the human thigh to position the leg. The third protrusion 32 can be inserted between the thighs to prevent the leg from being distorted relative to the waist and buttocks.

As shown in Figures 7 and 9, further, the connecting portion 2 includes a hip supporting portion 21 symmetrically arranged along a vertical plane where the midline of the human body is located. When the hip supporting portion 21 is observed from a side angle, the hip supporting portion 21 is bent toward the side away from the human body's buttocks. When the hip supporting portion 21 is observed from a cross-sectional angle, the side of the hip supporting portion 21 is bent toward the side close to the human body's buttocks to embrace and support the human body's buttocks. A second protrusion 22 is also arranged in the middle of the connecting portion 2, and the second protrusion 22 is inserted between the human body's buttocks to achieve buttocks posture correction.

Specifically, the connection part 2 embraces and supports the human buttocks on both sides, and the surface of the connection part 2 fits the curve of the human buttocks to locate the position of the buttocks. The second protrusion 22 can be inserted between the buttocks to prevent the buttocks from being distorted relative to the waist and legs.

As shown in Figures 2 to 9, further, a first outer edge 13 is set on the outer side of the lumbar support part 1, a second outer edge 23 is set on the outer side of the connecting part 2, and a third outer edge 33 is set on the outer side of the hip and leg part 3. The first outer edge 13, the second outer edge 23, and the third outer edge 33 are all bent toward the side away from the human body, so they will not hit the edge of the seat when in use, thereby improving the safety of the seat.

As shown in Figures 1 and 8, further, the first raised portion 12, the second raised portion 22, and the third raised portion 32 are on the same axis and are connected in sequence, ensuring that the axes of the waist, legs, and buttocks are on the same vertical plane, which has a better effect on correcting the posture and shaping of the human body as a whole.

As shown in Fig. 5, Fig. 6, Fig. 8 and Fig. 9, further, the seat comprises a frame 4 and a sponge 5 arranged on the surface of the frame 4, and the frame 4 and the sponge 5 are formed by molding to form the lumbar support part 1, the connecting part 2 and the hip and leg part 3. Specifically, the frame 4 is integrally molded by injection molding, the frame 4 is placed in the mold, and the sponge 5 is foamed on the frame 4. The thickness of the sponge 5 at the first raised part 12, the second raised part 22 and the third raised part 32 is greater than the thickness of the surrounding sponge 5.

As shown in FIG. 10 , further, a protrusion 24 is provided at the lower end of the frame 4 , and the protrusion 24 is inserted into a bracket (not shown) at the bottom of the seat to prevent the seat from tilting and shaking.
