Safety seat capable of protecting neck from falling down
Technical Field
The invention relates to the technical field of safety protection, in particular to a safety seat for protecting a neck from falling.
Background
The chair is a chair with a backrest and armrests, and is an indispensable article in the life of people. A large number of statistical materials indicate that with the increasing level of modern living, many spinal disorders in sitting positions, particularly low head workers, are extremely high in incidence, including housewives, embroidery women, office workers, typewriters, fitters on instrument lines, and the like. Spinal disease is the pathological changes of bones, intervertebral discs, ligaments and muscles of the spine, and further stresses and pulls spinal cords, spinal nerves, blood vessels and autonomic nerves, so that complex and various symptoms appear. The common disease is cervical spondylosis and lumbar spondylosis. The main symptoms are as follows: inability to stand upright, headache, dizziness, blurred vision, reduced memory, soreness of neck and shoulders, inappetence, regurgitation, vomiting, weakness of lower extremities, and paralysis may occur in severe cases.
Clinical diagnosis of the spondylopathy shows that the disease causes of the spondylopathy are symptoms such as local muscle hardening, poor blood flow, dislocation of spinal joints caused by different muscle tensions on two sides of the spine or protrusion of intervertebral disc caused by long-term overlarge pressure between spinal joints, thus pressing nerves to cause incapacitation, headache, dizziness, blurred vision, memory decline and the like caused by long-time keeping of the same sitting posture, standing posture and prone posture. Therefore, professions most prone to spine diseases are often persons working in the same posture, such as business families, office staff, designers, computer engineers, and the like. Research shows that the muscle temperature is raised, the vibration can promote the blood circulation in the muscle, and the muscle hardening is prevented, so that the elasticity of the muscle is ensured, the unbalance of the tension of the muscles at two sides of the spine is prevented, and the formation of the spinal disease can be effectively prevented.
