The cushion 200 is mounted removably in the mounting slot 121 and attached to a front wall of the cavity 110.

The user carries the load reducing backpack on the his back, the shoulder straps 101 hang on the user's shoulders. Adjust the lengths of the shoulder straps 101, so that the cushion 200 attaches against the user's waist to form some gap between the back of the load reducing backpack and the user's back, thereby disperse the pressure of the load reducing backpack and the articles therein on the user's shoulder and the user's waist, and reducing the pressure on the user's back and the user's shoulders.

The cushion 200 is mounted in the mounting slot 121, the cushion 200 and the back pad 120 are perpendicular to each other to form a stable structure, which can support effectively the articles in the load reducing backpack and disperse the pressure of the articles, thereby reducing the load on the user's shoulder and back, so that the user do not feel tired and discomfort. If the articles in the load reducing backpack are too heavy, the users can also add a plenty of cushions 200 to improve the reducing load effect.

In the embodiment, the back pad 120 is sewn in the main body 100.

In some embodiments in the present invention, referring to FIG. 1 and FIG. 2, the cavity 100 contains a mounting plate 111 arranged above the mounting slot 121, a side of the mounting plate 111 is fixed with an inner wall of the cavity 120. When the cushion 200 is mounted in the mounting slot 121, a bottom surface of the mounting plate 111 attaches to the cushion 200, a top surface of the mounting plate 111 is provided rotatably with a plurality of soft plates 1111. The soft plates 1111 can hold some cards, keys, etc., which further enriches the types of stored articles of the cavity 110, and improving the practicality.

When the cushion 200 is mounted in the mounting slot 121, the mounting plate 111 can further press the cushion 200 so that the cushion 200 can not take off the mounting slot 121.

In some embodiments in the present invention, referring to FIG. 1 and FIG. 2, the inner of the mounting plate is fixed with a plurality of elastic members 1112. When one side of the cushion 200 is inserted into the mounting slot 121, the elastic members 1112 are pressed by the cushion 200, thereby applying an reverse force to the cushion 200 to fix it securely in the mounting slot 121, which enhances the pressing effect of the mounting plate 111 on the soft plates 1111.

In the embodiment, the elastic members 1112 are re linear compression spring.

In some embodiments in the present invention, referring to FIG. 3, the cushion 200 comprises a straight plate 210 and a curve plate 220, the straight plate 210 is fixed with the curve plate 220, the curve plate 220 is mounted in the mounting slot 121 removably, the straight plate 210 attaches to the front wall of the cavity 110. Specifically, the straight plate 210 covers a whole bottom part of the load reducing backpack and plays the function of supporting the articles in it. The curve plate 220 is overfitting with the mounting slot 121. So that, when the curve plate 220 is mounted in the mounting slot 121, it is fixed therein, thereby fixing the cushion 200.

In some embodiments in the present invention, referring to FIG. 4, the cushion 200 comprises a straight plate 210 and an edge plate 230 which are fixed together. The edge plate 230 is inserted into the mounting slot 121 removably. The straight plate 210 attaches to the front wall of the cavity 110. Specifically, the edge plate 230 is a triangle edge plate, mounted in the mounting slot 121, the edges of the edge plate 230 are coupled with the wall of the mounting slot 121 so that the cushion 200 is generally mounted within the cavity 110 securely.

In some embodiments in the present invention, referring to FIG. 5, the surface of the back pad 120 is provided with a plurality of elastic bulge particles 122, which are equidistant distributed. Because of the existing of the elastic bulge particles 122, there is breathable space between the user's back and the back pad 120. The heat, generated by the friction of the user's back and the back pad 120, can be discharged outward through the breathable space. The reducing load bag has good air permeability, the users are not easy to sweat when carrying it.

In some embodiments in the present invention, referring to FIG. 5, the rear part of the main body 100 is provided with a first cotton block 130, a second cotton block 140 and a third cotton block 150. The first cotton block 130 and the second cotton block 140 are fixed above the rear part of the main body 100 symmetrically. Specifically, the first cotton block 130 and the second cotton block 140 are arranged a left side and a right side of the upper portion of the rear part of the main body 110.

When using, the first cotton block 130 and the second cotton block 140 attach tightly to the user's shoulders, which can disperse effectively the pressure on the user's shoulders, that is, to a certain extent to relieve the pressure on the user's shoulders, so that the user is not easy to feel tired. The third cotton block 150 is fixed the lower portion of the rear part of the main body 100, corresponding to the user's waist, and disperse the pressure on the waist of the user's waist effectively and reducing the pressure on the user's waist.

In some embodiments in the present invention, referring to FIG. 5 and FIG. 6, the bottom part of the main body 100 is provided with a thick plate 160, between which and the main body 100, there is a baffle 170. The thick plate 160 enhances the load capacity of the backpack and increases the capacity of the backpack.

The baffle 170 is made from plastics for shock-absorbing, if the backpack is hit accidentally, it provides certain protection.

In some embodiments in the present invention, referring to FIG. 5, the cavity 110 contains a partition 112, which is fixed with the inner wall of the cavity 110 and divides the cavity 110 into a primary storage chamber 113 and a secondary storage chamber 114. In the embodiments, one end of the partition 112 is fixed with the bottom of the cavity 110. The cavity 110 is divided into a plurality of storage layers, which facilitates the user to store articles according to the size, shape and facilitate the removal and release of articles.
