Title:
BACKPACK HAVING LOAD-REDUCTION AND CORRECTION FUNCTIONS
Document Type and Number:
WIPO Patent Application WO/2023/130195
Kind Code:
A1
Abstract:
Provided in the present invention is a backpack, comprising a longitudinal supporting member, which has a first end portion corresponding to the shoulders of a human body and a second end portion corresponding to the waist of the human body; a backpack body, which is independent of the longitudinal supporting member and has a top end corresponding to the first end portion and a bottom end corresponding to the second end portion, the backpack body being obliquely arranged relative to the longitudinal supporting member; and at least one transverse connecting member, which is connected to the longitudinal supporting member and the backpack body and at least partially maintains the inclination of the backpack body relative to the longitudinal supporting member, wherein a first transverse spacing between the first end portion and the top end is greater than a second transverse spacing between the second end portion and the bottom end. The waist or the back bears part of the weight of the backpack body, such that pressure on the shoulders is reduced, thereby achieving a load reduction effect. In addition, the backpack body inclines to the right to create a backward stretching force on the shoulders, thereby achieving an effect of correcting curved shoulders and a curved back.
