Abstract

The invention discloses a sitting posture adjusting device. The device comprises a connecting piece, a sitting piece, a waist cushion and shoulder limiting pieces; one side of the connecting piece isrotationally connected with one side of the sitting piece; the shoulder limiting pieces are arranged on the upper portion of the connecting piece, and the waist cushion is located at the joint of theshoulder limiting pieces and the connecting position; the waist cushion and the shoulder limiting pieces are located on the same side of the connecting piece; the connecting piece is connected with the waist cushion through a transmission device, and the rotating movement between the connecting piece and the sitting piece enables the waist cushion and the shoulder limiting pieces to move in the same side direction through the transmission device; the waist cushion is provided with a curved surface, and the side, away from the connecting piece, the curved surface protrudes. According to the device, the pulling force, caused by incorrect sitting postures, on a backrest part can be converted into backward supporting force of a middle waist supporting part and the pulling force of the sittingpiece to the bottom of the backrest part, and the force of the three parts is natural and comfortable force which scientifically depends on the formation of biological feedback and is not the stress formed by forcibly constraining an external device, so that discomfort is eliminated, and the posture correcting effect is improved.

Description

technical field [0001] The invention relates to a device for adjusting a sitting posture and a method for adjusting a sitting posture of a human body, belonging to the field of daily life appliances. Background technique [0002] Adolescents and children are at a critical moment of growth and development. Due to the current academic pressure, they spend more and more time sitting and studying.
