Description

Backpack

Technical Field

The utility model relates to the technical field of backpacks, in particular to a backpack.

Background

The knapsack is a common article carrying device and is commonly used in traveling, mountain climbing, working and other scenes. Modern backpacks typically use high strength, lightweight materials such as nylon, polyester fiber, etc. to ensure the life and portability of the backpack. The improvement design of the knapsack comprises the aspects of braces, back pads, outer bags and the like aiming at the comfort of the knapsack, and the factors of ergonomics, load distribution and the like are required to be considered, so that the characteristics of comfort, safety, easiness in use and the like of the knapsack are realized. The back pad and shoulder straps are the most important comfort components in backpacks, and are usually made of soft, breathable and well-supported materials; the shoulder strap is large, soft and adjustable to reduce the pressure on the shoulder and neck; the back pad may be thickened or hollow to enhance back support and breathability. The waistband can transfer the weight of the backpack from the shoulder to the waist, and lighten the burden of the shoulder, therefore, the waistband is generally designed to be wide, soft and adjustable and has good supporting force; furthermore, the position of the waistband should be appropriate to ensure that the weight can be correctly distributed.

Although the conventional backpack has many improved designs for comfort, the load of the backpack is still mainly distributed on the shoulders of the user, and for the user who uses the backpack for a long time, the user often needs to pull the braces to adjust the gravity center of the backpack, and the backpack is close to the back of the user, so that the comfort of the backpack is improved. However, the lack of points of force on the back strap of the existing backpack makes it quite inconvenient for the user to adjust the center of gravity of the backpack when pulling the back strap.
