Definitions

  • the invention relates to a bionic and posture-correcting backrest for study, and more particularly to a bionic and posture-correcting backrest for study for primary school students.
  • forward sitting position is defined if a person's upper body gravity is right on or in the front of the ischiatic tuberosity, where the balance is maintained by the back muscles and thighs.
  • Backward sitting position is defined if a person's upper body gravity is behind the ischiatic tuberosity, where the back must be against the backrest. It is apparent that the forward sitting position is likely to cause fatigue while the backward sitting position is not. However, students are fond of using the forward sitting position to study by bending over the desks. From the perspective of the physiology, when your line of sight is perpendicular to the object you are looking at, the image projected onto your retina is the clearest.
  • All the positions are contributable to correct sitting, reading, writing, and listening, i.e. a fist distance between chest and edge of desk and a foot from eyes to books.
