Abstract

The invention discloses a seat mechanism for correcting a sitting posture. The seat mechanism comprises a seat surface part and a seat backrest part, wherein the two ends of a first rod of the seat surface part are connected with a rack I and a movable pair I respectively; the two ends of an air spring are connected with the middle positions of the rack I and the first rod respectively; a second rod in the seat backrest part is connected with a third rod; the middle position of the second rod is hinged with a rack II; the other end of the third rod is fixedly connected with a movable pair II; a fourth rod is connected with a fifth rod; the middle position of the fourth rod is hinged with a rack III; the other end of the fifth rod is fixedly connected with a movable pair III; a sixth rod is connected with a seventh rod; the middle position of the sixth rod is hinged with a rack IV; the other end of the seventh rod is fixedly connected with a movable pair IV; the other end of an eighth rod is fixedly connected with a head pillow; the middle position of the eighth rod is hinged with a rack V. The seat mechanism for correcting the sitting posture has an obvious effect on correcting postures of all sections of a vertebral column of a human body; the system can realize multi-joint isolated degree-of-freedom movement and has a good posture correction function on a back posture when the human body sits down normally.

Description

technical field [0001] The invention relates to a seat mechanism, in particular to a novel seat mechanism for correcting sitting posture. Background technique [0002] In daily social life, white-collar workers and students who operate computers for a long time can easily cause the muscles of the waist, buttocks and legs to be in a state of tension for a long time due to the long-term fixed sitting posture. Bad sitting habits can cause myopia and strabismus for students , hunchback, and serious consequences of spinal curvature; for computer operators, long-term unreasonable sitting postures can easily lead to lumbar hyperplasia, and make the posterior longitudinal ligament tense and lose elasticity, causing lumbar disc herniation and compression of nerve roots. Compression of the sciatic nerve can lead to radicular sciatic nerve pain, serious consequences such as low back pain, lower limb pain, and mobility impairment. At present, except for the wearable posture-correcting ...
