ABSTRACT:
An inflatable flotation assembly includes a compressed gas cylinder stored inside a split housing the parts of which are held together by a releasable pivot on one end and an interlocked pivoted arm at the other end which engages a flexible tab aligned against the gas cylinder. The arm overlies the housing to engage the releasable pivot and when unclasped from this engagement will rotate to pierce the cylinder by deflecting the tab. Thereafter the expansion of a flotation bladder separates the housing while the arm remains interlocked to the tab to control the rate of gas release into the bladder by the angular inertia of the arm around its pivot.
