<p>An improved life raft with inflatable tubes having a boarding ramp attached to such raft wherein the raft is inflated by a hose interconnected by a coupling means and via a second hose to the raft such that the pressurized life raft chamber inflates the boarding ramp. The coupling means is a quick disconnect coupling means which in a connected condition is operative to main a flow connection between hoses and chambers but in a disconnected condition is operative to block the flow connection from both hoses and their respective chambers. A tension member is used to interconnect the quick disconnect coupling means to the raft and provides the means for disconnecting the coupling means when sufficient tension is provided as extending the distance between the coupling means and the raft. Such coupling means with the tension member can also be installed between the main inflating cylinder and the raft.</p> |
