Respective regions provide support, and center of gravity pressure is nearly all on vertebra, and this brings larger pressure to vertebra, and due to half
Chair all without bustle, therefore also extremely serious to lumbar vertebrae pressure-bearing, the time is permanent, and if things go on like this, vertebra is easily deformed, turned round
Song is gently then had a pain in the back, heavy then can cause sciatica, waist dish outstanding, a series of diseases such as osteoproliferation.And if it is
Abnormal sitting posture, the probability bigger of that deformation of spinal column, and backbone is an important composition organ of trunk, including vertebra, chest
Vertebra, lumbar vertebrae, stubble vertebra and tail bone to the spreading of the support of trunk, movement and spinal nerve, are protected and have particularly significant work
With influencing many normal physiological functions, heavy then entail dangers to life if impaired light.Therefore, various in order to protect backbone
Nursing chair operation and give birth to, but these nursing chairs are expensive, dynamic then hundreds and thousands of, and the indoor popularization of routine office work is made
With more difficulty.And there is also following problems for commercial type some back cushions：
The neckpillow and waist of existing aggregate protection vertebra rest the head on integrally formed office chair back cushion, and neckpillow mostly uses greatly U-shaped pillow,
But its U-shaped pillow and back cushion or the perpendicular direction fixed design of human body back, i.e. its U-shaped opening direction H is vertical with human vertebra,
I.e. when human body is leaned on into the neckpillow, two U-shaped sides of the U-shaped pillow are come respectively with the direction of vertical vertebra insertion neck both sides with this
Support vertebra.But due in this mode, the U-shaped opening direction of U-shaped pillow 1 be it is fixed, this result in that human body takes a seat when
Wait it is more inconvenient, U-shaped side outstanding can pair human body back that do not take a seat also make obstruction.
2, current integrally formed neckpillow, waist pillow and back pillow, all parts shape are then difficult to be changed once shaping,
It is unfavorable for user and phase permeability curve adjusting is carried out to respective sitting posture when in use.
