The invention belongs to the technical field of airplane oxygen/life support system design, and relates to an airplane cockpit explosion decompression human body protection vest which comprises a vest face body, a pre-tightening air bag, an air generator, an exhaust valve and an electronic oxygen regulator. The pre-tightening air bag, the gas generator and the exhaust valve are arranged on the clothes surface main body, the electronic oxygen regulator is arranged on the ejection seat, and the pre-tightening air bag is arranged in the clothes surface main body; when the ejection seat explodes to reduce pressure, the electronic oxygen regulator senses pressure change and controls the gas generator to work, the gas engine inflates the pre-tightening air bag and the airfoil main body to expand, so that the upper body of a human body is pre-tightened, counterforce pressure is established on the body surface, excessive expansion of lung tissue is effectively reduced, and damage to the lung tissue is avoided; after 2 seconds, an exhaust signal is sent to the exhaust valve, the exhaust valve is opened, pressure in the pre-tightening air bag is relieved, pressure on the human body is removed, and work is simple and efficient.
本申请属于飞机氧气/生命保障系统设计技术领域,为一种飞机座舱爆炸减压人体防护背心,包括衣面主体、预紧气囊、气体发生器、排气阀和电子氧气调节器;预紧气囊、气体发生器和排气阀设于衣面主体上,所述电子氧气调节器设于弹射座椅上,所述预紧气囊设于衣面主体内部;当弹射座椅发生爆炸减压的瞬间,电子氧气调节器感应到压力变化,控制气体发生器工作,气体发动机向预紧气囊内充气,翼面主体膨胀,从而对人体上身进行预紧,在体表建立对抗压力,从而有效减少肺组织的过渡膨胀,避免肺组织损伤;2s后发送排气信号至排气阀,排气阀打开,卸除预紧气囊内的压力,去除人体的受压,工作简单高效。
