    • A breathing apparatus for survival gear is provided by a head receiving hood that is sealed over the head of the user and has sufficient volume to provide breathing air for at least a selected period of time while submerged and is made of a material that prevents the ingress of liquid water while being permeable to the flow of gasses therethrough whereby the supply of oxygen in the hood may be replenished and the carbon dioxide concentration reduced. A suitable waterproof transparent window is formed in the hood in the position which permits the wearer to see out of the hood and a gas passage spacer pad prevents the hood from collapsing into the breathing apertures of the user and provides passages communicating with the inside of the hood remote from the breathing passage.
    • 用于生存齿轮的呼吸器由头部接收罩提供,该头部接收罩被密封在使用者的头部上,并且具有足够的体积以在浸没时至少选定的时间段提供呼吸空气,并且由防止入口的材料制成 的液态水,同时可以通过气体流通,从而可以补充发动机罩中的氧气供应并减少二氧化碳浓度。 在罩中形成适当的防水透明窗口,该窗口允许穿戴者从罩中看到的位置,并且气体通道隔离垫防止罩子塌陷到使用者的呼吸孔中,并提供通向与使用者的内部连通的通道 罩远离呼吸通道。

    • An atmospheric air pressure inflatable garment has an inner layer and outer layer define a confined space with a compressible material therein. The compressible material has resiliency and strength characteristics so that it compresses under atmospheric conditions when the air pressure in the confined space is reduced to sub-atmospheric pressure and an air passage adapted to permit passage of air into and out of the confined space but not water when a seal for sealing the passage is released. The garment is stored with the air removed and permitting atmospheric air to fill the space when the seal is opened raise the pressure in the space to atmospheric and causes the compressible material to expand separating the inner and outer layers and forming an insulation therebetween.
    • 大气压充气衣服具有内层和外层,其中限定空间与其中的可压缩材料。 可压缩材料具有弹性和强度特性,使得当密闭空间中的空气压力降低到低于大气压力时,它在大气条件下压缩,并且空气通道适于允许空气进入和离开受限空间而不是水 当用于密封通道的密封件被释放时。 存储衣物,除去空气,并且当打开密封件时,允许大气空气填充空间,将空间中的压力升高到大气压,并使可压缩材料膨胀分离内层和外层并在其间形成绝缘。
