Sea-rescue overall safeguarding unconscious wearers - embodies tubes inflatable to bring wearer to sitting position from prone position

摘要

The overall garment safeguarding unconscious wearers is a conventionally-cut overall suit but embodies a system of tubular inflatable chambers. Inflatation with a buoyancy-producing medium can be manual or, after a predetermined delay, automatic and brings the wearer into a sitting position, semi-submerged. A tube extension above the wearer's head will turn him upright if floating head-down; for keeping the head above water there is a collar-tube. For service in cold regions, additional pockets are fitted containing material forming foam-pads, but only after prolonged immersion and over extra-sensitivity areas.
