摘要： A backframe for a self contained breathing apparatus (SCBA) is formed of a molded shell (10) having some depth, and a closure plate (11) fixed to the shell to provide an enclosed volume. The molded shell (10) with the closure plate (11) yields a good weight-to-strength ratio, and provides a water and dust-resistant enclosure for control components of the SCBA. A water-tight battery compartment (14) is enclosed within the shell so the batteries are separated from other components. A low air pressure alarm provides an auditory signal, and may also include a tactile signal. A buddy breathing hose (30) can be pulled from the backframe to provide a reasonable length tether; and, by connecting two such buddy breathing hoses, twice the length is provided.

摘要： A self contained breathing apparatus has a display of air pressure within the face mask in the field of vision of the user of the breathing apparatus. The display is four lights that indicate the four quarter-tanks of pressure, and the lights change to indicate the amount of air remaining. A transducer receives tank pressure and provides an electric signal. The air pressure is placed on a bourdon tube which rotates a disk in response to changes in pressure. One half of the disk includes a gradient, and a light source emits light through the gradient to be received by a light sensor. As the disk rotates, the gradient varies the amount of light received by the sensor, so the electrical output of the sensor varies.

摘要翻译： 用于自给式呼吸器（SCBA）的后框架由具有一定深度的模制壳体（10）形成，并且封闭板（11）固定到壳体以提供封闭容积。 具有封闭板（11）的模制外壳（10）产生良好的重量与强度之比，并为SCBA的控制部件提供防水防尘外壳。 外壳内装有一个防水电池仓（14），使电池与其他部件分离。 低气压报警器提供听觉信号，并且还可以包括触觉信号。 伙伴呼吸软管（30）可以从后框架拉出以提供合理的长度系绳; 并通过连接两个这样的好友呼吸软管，提供两倍的长度。
