A compound pressure relief structure includes a first pressure relief part, a second pressure relief part, a gas pipe, an inflation part, a control circuit and a controller. The first pressure relief part is provided with a first air bag, the second pressure relief part is provided with a second air bag, one end of the gas pipe is connected with the first air bag, the inflation part is connected with a first air release part and a second air release part, and the first air release part is connected with the first air release part. At the other end of the air pipe, the second air release part is connected with the second air bag, the control circuit is connected with the air inflation part, and the controller is connected with the control circuit.So that when the human body has two parts at the same time, such as the upper part of the back,When the waist is against,By means of the inflator to the first,The second air bag inflates.The first airbag is inflated and pushed over the back.To form a fulcrum in the neck.The head, neck, shoulders, back and shoulders are extended.Chest enlargementThe function of activating collaterals,And inflate the second air bag up to the waist.Let the body stretch comfortably；In addition,The first,Inflation and deflation of the second air bag,Make the first airbag have different pushing angle.It can also adjust the head, neck, shoulder, back and extension.The extent of chest enlargement,The second air bag has different top waist height.To meet the needs of individuals,Promote blood circulation,Eliminate fatigue, etc.It has the effect of health care.一種複合式紓壓結構，係包含一第一紓壓部、一第二紓壓部、一氣管、一充氣件、一控制電路、一控制器，該第一紓壓部設有一第一氣囊，第二紓壓部設有一第二氣囊，該氣管一端連通該第一氣囊，該充氣件連接一第一洩氣件、一第二洩氣件，該第一洩氣件連通該氣管另一端，該第二洩氣件連通該第二氣囊，該控制電路連接該充氣件，該控制器連接於該控制電路。俾當人體同時以二部位如背部上方、腰部抵靠時，藉由充氣件對第一、第二氣囊進行充氣作用，使第一氣囊膨脹頂推背部上方，用以頸部形成支點，構成頭頸肩後仰及肩背伸展、擴胸、活絡之作用，及使第二氣囊膨脹向上頂高腰部，讓人體得以舒適地進行伸展運動；另外，可藉控制器調整第一、第二氣囊之充氣與洩氣，使第一氣囊產生不同之頂推角度，亦即可調整頭頸肩後仰角度及肩背伸展、擴胸之大小程度，及使第二氣囊產生不同之頂腰高度，進而符合個人之需求，促進血液循環、消除疲勞等，具有身體保健之功效。
