Abstract
A backpack is provided. The backpack includes: a longitudinal supporting element, a first end of which is opposite to the shoulder and the second end opposite to a waist of the user; a main body includes a top end, a middle part and a bottom end; the main body is inclined relative to the longitudinal supporting element; and a transverse connector connects the longitudinal supporting element to the main body, and maintains the inclination of the main body relative to the longitudinal supporting element. A portion weight of the main body is shared by the waist or back, reducing the pressure on the shoulders and achieving a load reduction effect. And the inclination creates a backward stretching force on the shoulders, thereby correcting the curvature of the shoulders and back.
