Description

Technical Field

[0001] The utility model relates to the technical field of sitting chairs, in particular to a sitting chair with a hollowed-out spine to protect the waist and spine. Background Art

[0002] With the accelerated pace of modern life, prolonged sitting has become the norm for people, including office workers, students, and drivers. However, traditional seated chair designs often overlook the natural curves and support needs of the human spine. Prolonged use can lead to health issues such as increased spinal pressure, lumbar disc herniation, and lumbar muscle strain. This is particularly true for chair backs, which traditionally utilize a solid structure. This compresses the spine over time, preventing effective relief and support, and increasing the strain on the spine.

[0003] In addition, although there are some sitting chairs with adjustment functions or local support designs on the market, most of them fail to accurately optimize the design for specific parts of the spine, especially in the key area where the spine contacts the chair back, and lack effective decompression and support mechanisms. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a sitting chair with a hollowed-out spine and waist and spine protection, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hollow spine waist and spine protection sitting chair, including a seat body, and also including:

[0006] A hollow portion, which is reserved and arranged on the top of the seat body and corresponds to the human spine;

[0007] Back cushions, the back cushions being symmetrically mounted on the top of the seat body and located on both sides of the hollow portion;

[0008] A seat cushion is symmetrically mounted on the bottom of the seat body.

[0009] Furthermore, the seat body includes a backrest and a seat of an integrated structure, and the connection between the backrest and the seat is configured as an arc-shaped structure.

[0010] Furthermore, a plurality of ventilation holes are reserved at the connection between the chair back and the chair seat, and the ventilation holes are of a trapezoidal structure.

[0011] Furthermore, the surfaces of the chair back and the chair seat are respectively mounted with a back cushion mounting plate and a seat cushion mounting plate through a plurality of buckles, and the back cushion and the seat cushion are respectively bonded to the surfaces of the back cushion mounting plate and the seat cushion mounting plate.

[0012] Furthermore, a plurality of sockets are reserved inside the back cushion mounting plate and the seat cushion mounting plate, and the buckles are inserted into the sockets.

[0013] Furthermore, a plurality of latch holes are reserved inside the chair back and the chair seat, and buckles are provided inside the latch holes.

[0014] The utility model provides a hollowed-out back-protecting and waist-protecting sitting chair. Compared with the existing technology, it has the following advantages:

[0015] This hollowed-out backrest and lumbar support chair features a hollowed-out section at the top of the backrest. This design cleverly avoids the natural protrusions of the human spine, so that when the user is sitting, the spine is no longer directly under pressure from the backrest, significantly reducing spinal pressure and helping to prevent and alleviate spinal disorders. The symmetrically mounted back cushions on either side of the hollowed-out section effectively support the muscles on both sides of the spine, sharing the pressure on the spine and surrounding tissues. This design not only enhances sitting comfort but also promotes blood circulation in the muscles on both sides of the spine, helping to prevent muscle fatigue and stiffness.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3The utility model provides a technical solution: a spine hollow waist and spine protection sitting chair, which consists of a seat body 1, a hollow part 2, a cushion 3, a seat cushion 4, a cushion mounting plate 5, a cushion mounting plate 6 and a buckle 7. The seat body 1 includes a chair back 11 and a seat 12 of an integrated structure. The hollow part 2 is reserved at the top of the chair back 11 and is "V" shaped, corresponding to the human spine. The cushions 3 are symmetrically installed on the top of the seat body 1, and the cushions 3 are located on both sides of the hollow part 2. When the user uses the chair When sitting on the posture chair, the hollow part 2 is set so that the spine does not contact the sitting chair, so that the spine does not need to bear the pressure of the body, and cooperates with the cushion 3 to support the muscles on both sides of the spine and distribute the pressure. The connection between the chair back 11 and the seat 12 is set as an arc-shaped structure, which fits the human waist and protects the waist. A plurality of ventilation holes 14 are reserved at the connection between the chair back 11 and the seat 12. The ventilation holes 14 are a trapezoidal structure. The setting of the ventilation holes 14 can prevent the user from feeling stuffy in the waist when using the chair.
