Abstract: Luggage, such as suitcases and backpacks, converts into personal flotation devices by incorporating flotation elements into their structure. Backpacks can also be converted to rescue harnesses by the incorporation of a reinforcing strap and rescue ring. Significantly, such multi-purpose items of luggage offer users access to safety devices unavailable to users of ordinary luggage, enabling such users to have access to lifesaving equipment without requiring the user to carry a dedicated PFD or rescue harness. In one embodiment a backpack includes an emergency lower opening that can be used to remove heavy items while the user is still wearing the backpack, to increase the buoyancy of the survival backpack by eliminating ballast. In another embodiment, a backpack includes a peripheral zipper that separates the backpack into first and second portions, one portion to be worn over the chest and the other portion to be worn over the back.

Abstract: Inflatable articles of clothing are disclosed. Using in many cases multiple plies of material impervious to air, inflatable pockets are created. Valves may also be included to facilitate introducing air into the pockets and, if necessary, to permit their deflation.

Abstract: A buoyancy compensation device has a plurality of guide assemblies disposed about its outer and inner periphery, such that a plurality of resilient bands can each be disposed in a pair of complementary guide assembles, the bands biased to restrain expansion of the bladder when deflated or partially inflated to reduce drag, increase comfort and improve air distribution.
