Benefits of technology
[0009]The current invention addresses the needs of the prior art and overcomes it's limitations by providing an inflatable safety belt of simple construction and design. The inflatable safety belt in accordance with the invention includes a flotation device having a pair of spaced apart inflatable chambers that, when inflated by a source of compressed gas, extend to positions proximate the user's chest to provide buoyancy to the user's upper body. Embodiments having a single or more than two inflatable chambers are also envisioned with according adjustment of the buckle and its placement when wearing (or elimination of the buckle is possible in an embodiment designed to be pulled on over the legs or head). In an embodiment, the belt is also inflatable and in fluid communication with the inflatable chambers that extend to the chest.
Problems solved by technology
The disclosed safety belts of the prior art suffer the disadvantage of being expensive to manufacture and difficult to use.
The safety belts of the prior art also suffer from unnecessary complexity in their design.

Abstract
An inflatable safety belt is disclosed. The inflatable safety belt includes a belt including a means for buckling the belt about a waist of a wearer, a pair of pockets disposed in spaced relationship along a length of the belt and oriented toward a top thereof, and a source of compressed gas in fluid communication with the pair of pockets and the belt, each of the pockets and the belt being inflatable into an inflated chamber extendable around the waist and about the front torso of the wearer's body.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to personal flotation devices and more particularly to a swimmer's safety belt that can be inflated to provide at least one and preferably two inflated chambers extendable to a position proximate the user's chest.[0003]2. Description of Related Art[0004]Inflatable personal flotation devices are well known in the art and are described in U.S. patents issued to Dennis Brown including U.S. Pat. No. 5,180,321, U.S. Pat. No. 5,368,512, U.S. Pat. No. 5,702,279, U.S. Pat. No. 6,036,562, and U.S. Pat. No. 6,394,866.[0005]U.S. Pat. No. 5,180,321 discloses a swimmer's safety belt including a substantially hollow belt, worn about the waist, and able to assume the shape of a life preserver in use, while allowing the wearer to swim to safety after entering the water. U.S. Pat. No. 5,368,512 discloses an inflatable swimmer's safety belt including a pair of belts, tethered together, to restrict the life p...
