Title:
SELF-ADAPTIVE BACK WIDTH STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/098560
Kind Code:
A1
Abstract:
The present invention relates to a self-adaptive back width structure, comprising a base plate connected to a back surface of a backpack. Multiple matching supporting assemblies are arranged corresponding to a human back on the side of the base plate distant from the backpack, and each supporting assembly comprises a movable block and a protective block fixedly arranged on the movable block. Each movable block is movably connected forwards and backwards to the base plate by means of a guide assembly, and elastic components are arranged between the movable blocks and the base plate, the elastic components being used for enabling the movable blocks to move away from the base plate. The self-adaptive back width structure of the present invention has a compact structure and is lightweight overall. The supporting assemblies enable the movable blocks and the protective blocks to move forwards and backwards a certain distance by means of the action of the elastic components according to the degree to which the human back presses against the base plate during use by people, so as to automatically adapt to the human back, thereby relieving and dispersing stress when the backpack is worn by people and protecting human spines and back muscles.
