Cushion pad for backpacks

Abstract

Disclosed herein is a cushion pad for backpacks. In the cushion pad of the present invention, a net fabric is provided on a portion of each of the backpad and the shoulder straps which are in close contact with the back and shoulder of a user. Furthermore, the cushion pad includes a porous filter which is placed inside the net fabric to dissipate heat to the atmosphere, and a sheet which is made of a material such as polyurethane and layered on a surface of the porous filter. The sheet is inserted along with the porous filter into a space defined between the net fabric and the cloth of the backpack. As such, the cushion pad having the above-mentioned structure provides superior ventilation and elasticity to the backpad and the shoulder straps of the backpack. In addition, the cushion pad of the present invention is lighter than conventional pads and has superior ventilation, thus preventing the backpack from being soaked with sweat, thereby being pleasant to the user who carries the backpack on his/her back.
