Abstract
An improved crew oxygen mask and stowage assembly combination ( ) is provided including a stowage box ( ) equipped with a door ( ), with a crew mask assembly ( ) made up of a mask ( ), gas-conveying tubing ( ) and valve unit ( ). The box ( ) also includes a valve-controlling switch lever ( ) for selective gas-on or gas-off operation of valve unit ( ). In normal conditions, the mask ( ) and tubing ( ) are stowed within box ( ) with lever ( ) oriented in the gas-on position, so that the tubing ( ) is pressurized and mask ( ) may be quickly pulled from the box ( ) and used. After such use, the switch lever ( ) is shifted to the gas-off position, causing the tubing ( ) to be depressurized; this allows easy restowage of the tubing ( ) and mask ( ) within the box ( ). However, when door ( ) is closed, the switch lever ( ) is cammed back to the gas-on position, thereby repressurizing tubing ( ) and returning the combination ( ) to a full-ready condition.
