Title:
INFLATABLE LIFE RAFT
Document Type and Number:
WIPO Patent Application WO/2010/058205
Kind Code:
A3
Abstract:
An inflatable life raft has a platform (12) or platform portion formed by two flexible panels (20,22) joined together by each of a plurality of threads (24) to limit the distance apart that the panels can be moved, the panels being sealed to each other at their edges to form a chamber. A sensor can detect when the life raft is in the water, and an inflation system is operable in response to such detection to inflate the chamber with a gas. Preferably, the threads have similar lengths so that, when the chamber is inflated, the panels are substantially parallel. Accordingly, it is possible to fabricate an inflatable life raft which does not balloon out and which can provide a substantially flat platform.
