Abstract
Abstract A housing for encasing a gas generator comprising a shell formed of a filament-wound epoxy comprising glass filaments bonded with epoxy and having vent passages therethrough. The shell is closed at the bottom end and is provided with a removable cover at the upper end. Breathing equipment is compactly stored within the upper end of the housing and is connected to the cover for removal therewith. A firing mechanism is operatively connected to the cover and is adapted to be actuated upon removal of the cover. A detent is mounted in the housing for indicating that the cover has been axially shifted. Mounting members are pivotally mounted on the shell of the housing for attachment to a fixed support structure. When detached, the mounting members serve as handles in manually carrying the assembly.
