Description

Technical Field

[0001] The utility model relates to the technical field of sitting chairs, in particular to a high-convex waist and spine protecting sitting chair. Background Art

[0002] With the shift in modern work and lifestyles, sitting for extended periods of time for work, study, or entertainment has become the norm. However, prolonged poor sitting posture often places excessive pressure on the waist and spine, leading to a range of health issues such as lumbar muscle strain, lumbar disc herniation, and spinal deformity. While traditional chairs can meet basic sitting and lying needs, they lack support, breathability, and ergonomic design, making them ineffective in effectively alleviating the discomfort and harm caused by prolonged sitting.

[0003] Specifically, the backrests of traditional chairs are mostly flat or simply curved. When in use, the user's spine comes into contact with the sitting chair, which puts pressure on the spine and cannot effectively disperse the pressure on the spine. Long-term use can easily lead to spinal fatigue and injury. Utility Model Content

[0021] 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.

[0022] See also Figure 1-4 The utility model provides a technical solution: a high-convex waist and spine protection sitting chair, which consists of a seat body 1, a backrest protector 2, a seat cushion 3, a backrest pad 4 and a seat cushion pad 5, wherein the seat body 1 is composed of an integrated seat back 11 and a seat 12, the backrest pad 4 and the seat cushion pad 5 are respectively connected to the seat back 11 and the seat 12 through a snap structure, and the backrest protector 2 and the seat cushion 3 are respectively bonded and fixed to the outer surfaces of the backrest pad 4 and the seat cushion pad 5 by glue. In order to improve the ventilation effect of the user's waist during use, ventilation holes 13 are symmetrically opened at the junction of the backrest 11 and the seat 12, and the junction of the backrest 11 and the seat 12 fits the user's waist, thereby protecting the waist;

[0023] A reinforcing rib 15 is provided in the middle of the seat body 1. The reinforcing rib 15 can be provided with a steel wire or an elastic material. The reinforcing rib can make the seat stretch when it is under pressure.

[0024] Please read Figure 4 The front middle portion of the chair back 11 is provided with an outwardly protruding rib 6, and the back middle portion of the chair back 11 is provided with an inwardly recessed inner groove 7, through which the protrusions of the ribs 6 just form a corresponding support with the groove of the human waist.

[0025] In addition, in order to protect the user's spine, raised support parts 21 are symmetrically provided on both sides of the chair back guard 2, and the raised support parts 21 are connected by recessed parts 22.
