Garment integrated personal flotation device

Abstract

Airway and equipment protective buoyant, rescue, marking and recovery devices are disclosed. A garment mounted dual zipper cover releases a bladder that creates a reliable mandibular shelf and bracket while simultaneously encapsulating the crico-thyroid cartilage protecting it from compression. A dual wall personal floatation device (PFD) with its over sized inner bladder creates extended midline crossing. A dual chambered inner bladder separates the compressed gas inflated high-pressure low-volume bladder required for corrective turning from the higher-volume lower-pressure orally inflated chamber which provides the additional buoyancy needed to improve freieboard. A dual release fabric lock handle allows for the quick release of the deflated redundant abdominal PFD which then serves as an accurately thrown rescue inflatable. A PFD integrated variable-displacement dual-pressure personal life raft uses compressed gas to inflate a rigid floor conferring sufficient buoyancy to support the Marines 35 lb. Rucksack.
