This creation is a pressure relief pad installed on the back frame and the back frame composed of it. Through this creation, the pressure at the contact point between the back frame and the body can be evenly distributed on the pressure relief pad, so that the wearer can move more comfortably and solve the problem that the learned pressure relief pad will cause discomfort to the wearer. The decompression pad installed on the back frame includes an air cushion and a re adhesive layer. The shape of one side of the air cushion can at least correspond to the shape of the place to be set on the back frame. The adhesive layer can be repeatedly arranged on one side of the air cushion opposite to the back frame.本創作係為一種裝設於背架之減壓墊與其組成之背架，透過本創作可將背架與身體接觸點的壓力平均分佈於減壓墊，使得穿戴者得以更加舒適地活動，解決習知減壓墊會造成穿戴者不適的問題。本創作之裝設於背架之減壓墊，其包括一氣墊與一可重覆黏貼層。氣墊的一面之造型至少可對應符合一背架上待設置處之外型。可重覆黏貼層設置於該氣墊對應該背架設置處之一面。
