发明名称 Backpack apparatus
摘要 A backpack assembly with top, bottom, front, primary back and side panels which together define a chamber within. A pair of shoulder straps are secured to the backpack such that, with the straps positioned over the shoulders of the person, the position of the front panel is generally parallel to the back of the person. The primary back panel is securely attached to a secondary back panel along the top edge and elastically attached along the sides forming a pocket in-between the back panels. When placed over the back chair rest, the pocket supports the backpack behind the chair. Thermal gradient pads and vibrational generation provide enhanced benefits of the backpack to the user.
