The utility model relates to the technical field of correcting instruments, and discloses a back supporting and posture correcting belt. The
back support comprises a fabric layer and a wing-shaped supporting plate, and the fabric layer is used for making contact with the
human body in an attached mode to increase the comfort degree; the number of the wing-shaped supporting plates is two, the two wing-shaped supporting plates are attached to the fabric layer in a
bilateral symmetry mode, the wing-shaped supporting plates are used for being attached to and supported on the lower posterior saw
muscle and the middle-lower erector spine
muscle on the corresponding sides, and the two wing-shaped supporting plates cooperate to jointly support the spine from the two sides of the spine and limit the spine. The middle and lower erector spine muscles of the
human body can be covered, the design of the wing shape conforms to the natural
radian of the
lumbar vertebra and fits the
waist curve, necessary supporting force is provided for posterior sawed muscles, erector spine muscles and other
peripheral muscular tissues, and the activity in other directions is not limited while the spine is supported and fixed; the supporting structure aims to solve the technical problems that an existing supporting structure of a posture correcting belt is insufficient in supporting strength, insufficient in
lumbar vertebra covering and poor in biomechanical adaptability.
