A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

This invention reveals a collar life preserver for water sports or similar that includes a compressed inflatable life preserver (1), a cartridge (2) that is filled with CO2, a solenoid valve (3) in connection with the cartridge (2), a discharge valve (4), a sensor (5) associated with a microprocessor (6) programmed with an algorithm and emission/reception means between the valve (3) and the microprocessor (6). The inflatable collar (1) presents a sensor (5) associated with the microprocessor (6) programmed with an algorithm that constantly receives information of the user's body functions and is capable of determining when the user is unconscious.

A persona! flotation device for a user comprises a bodywear member, as well as a container containing buoyant gas and an actuation assembly, both of which are mounted to the bodywear member. The bodywear member is to be worn to by the user such as on the wrist or the neck. The actuation assembly is in operative communication with the container containing buoyant gas for selectively being actuated so as to provide fluid communication between the container containing buoyant gas and the inflatable member. Actuation of the actuation assembly provides for releasing the buoyant gas into the inflatable member causing the inflatable member to inflate and provide buoyancy to the persona! flotation device.

A rescuing and positioning assembly includes a bag which is inflatable; a surface of the bag having textures or drawings for displaying rescue indications; an inflation device for inflating the bag; a connecting wire having one end connected to the bag; a light emitter installed on the connecting wire; and a bracelet connected to another end of the connecting wire; the bracelet used to be worn on the user's body so that the bag may be tied to user's body for indicating where the user is and for avoiding to separate from the user. In use, the bag is inflated by using the inflation device, and the bracelet wears on the user's body. Thus, the user can float on water. The bag could indicate a position of the user and textures or drawings on the bag and light from the light emitter will alert others to keep attention to the user.

The invention includes a floatation device. The floatation device includes a body fabricated from a buoyant foam, and the body comprises an outer side wall, a top side comprising a downwardly sloped portion and a level portion, an inner opening at the center of the level portion, and a division extending from the outer side wall to the inner opening. The floatation device may also include one or more front, rear, and/or side extensions as well as one or more inserts, in some embodiments.

A swim training flotation device system includes two oblong inflatable bags connected to a belt worn about a swimmer's waist. The swim training flotation device allows swimmers to move from a vertical position to a horizontal position and from a prone position to a supine position without adjustment of the device. In addition, the device does not inhibit a swimmer's arm stroke and the device promotes a neutral swimming position.

An inflatable personal flotation device worn about the waist level as a belt or as incorporated into a swimming garment is disclosed, that is inconspicuous and may be worn over, under or even be incorporated into almost any type of apparel. This waist belt PFD in its uninflated state is practical, comfortable, attractive and inconspicuous. The PFD contains an outer compartment housing a buoyancy component, activated by pressurized gas or other means, and has one or more straps to secure the device to the wearer. Upon inflation the apparatus, being deployed and powered by its own buoyancy, rises above the waterline into a rescue configuration turning and positions a wearer upright with their head above water.

An inflatable personal floatation systems includes the manually inflated personal floatation device for aviation use including arm-strap loops, an inflation pull cord, a pack breakaway tether, and an inflation canister, a sealed pouch, an individual floatation device pack and a strap. The individual floatation device is configured to be worn in a waist belt. The individual floatation device is housed within the sealed pouch and connected to the sealed pouch via the pack breakaway tether. The inflatable personal floatation system provides a safety device for the user-wearer.

This invention reveals a collar life preserver for water sports or similar that includes a compressed inflatable life preserver (1), a cartridge (2) that is filled with CO2, a solenoid valve (3) in connection with the cartridge (2), a discharge valve (4), a sensor (5) associated with a microprocessor (6) programmed with an algorithm and emission/reception means between the valve (3) and the microprocessor (6). The inflatable collar (1) presents a sensor (5) associated with the microprocessor (6) programmed with an algorithm that constantly receives information of the user's body functions and is capable of determining when the user is unconscious.

An air bag structure includes an air bag body. The air bag body includes a first air bag, a second air bag, and an intermediate partition disposed between the first air bag and the second air bag. The intermediate partition is extensible. When one of the air bags is broken, the other air bag is inflated. The intermediate partition is deformed to move toward the rupture, and the air volume of the good air bag is doubled and returned to the original air volume, thereby maintaining buoyancy.
