Abstract

The invention relates to a knapsack strap and a breathable strap pad, belongs to the field of bags and suitcases, and discloses a strap and a strap pad applied to a knapsack or a schoolbag, and adopts the technical scheme that the breathable strap pad is formed by injection molding of elastic plastic or punching of a foaming material, and the breathable strap pad is provided with breathable holes; the breathable strap pad is arranged between an upper-layer screen cloth and a lower-layer screen cloth to serve as an interlayer, and a layer of cloth is additionally arranged outside the upper-layer screen cloth for shaping when needed. The breathable strap pad is advantaged in that due to the fact that the strap pad is made of elastic plastic or foaming materials through punching, the weight is light, and due to the fact that the strap pad is provided with the breathable holes, an upper layer of straps of the backpack is changed into the mesh cloth with good air permeability, so the straps are vertically through and very good in air permeability, particularly, the strap pads are made of elastic plastic in an injection molding mode, transverse elasticity is good, and due to the fact that the side view is wave-shaped, longitudinal flexibility is high, and the backpack is more comfortable to carry.

[0002] Backpack is a common item in people's life, and it is necessary for travel. For students, schoolbag is essential. In order to make it more comfortable to carry, backpacks and schoolbags have added cushions to their straps, all of which are made of sponge or pearl cotton. If the material is thickened, these materials can achieve a little soft decompression effect, but due to the lack of lateral elasticity of these materials, the shoulders will be stressed unevenly, and long-term carrying will cause soreness on the shoulders. The existing straps are all made of mesh It is made of sponge or pearl cotton in the middle of the fabric. The upper layer is made of fabric, and the lower layer is made of mesh. Because the sponge or pearl cotton and the fabric have no air permeability, especially the material with poor heat dissipation of the sponge or pearl cotton, it is difficult to wear it when it is hot. Feels stuffy and not as comfortable as expected
