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.

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.

A buoyancy assistance kit including a belt for surrounding part of the trunk of a user and two armbands each surrounding part of an arm of said user respectively, the belt and the armbands each including at least one element arranged so as to ensure a buoyancy assistance function, each armband being connected to said belt by an element, each element having an elasticity which allows the relative position of the armband to be adapted in relation to the belt when being worn.

The present invention relates to a floatation device for encumbered people carrying equipment such as military personnel and offshore workers. Ideally, the floatation device includes an auxiliary floatation device for encumbered users that can be used with a primary lifejacket worn by a user. The auxiliary floatation device includes a buoyancy portion that, in 5 use, can be attached to the legs of the user, and the orientation of the torso of the user is controlled by the buoyancy force provided by the buoyancy portion and, in turn, effect the distance between the mouth of a user and waterline, which is referred to as the freeboard.

A lifesaving device and a lifesaving control method are provided. Wherein, the lifesaving device includes: at least one first detection module (200) configured for detecting human body biological characteristic information, a lifesaving device body (100) capable of being worn on a body of a user, and at least one first gasbag module (300) arranged on the lifesaving device body (100); after the first gasbag module (300) is activated, a lifesaving gasbag (1) can be popped up; the first detection module (200) is in signal connection with the first gasbag module (300) and is configured for activating the first gasbag module (300) when the biological characteristic information detected meets a first preset condition.

A wearable dress unit comprising a garment assembly, an inflatable bladder connected to the garment assembly, a plurality of connection structures disposed on an exterior of the garment assembly, an inflation assembly disposed in fluid communication with an inside of the inflatable bladder, and a pocket structure. The garment assembly is wearable at all times when worn in a conventional position, and provides flotation when removed and disposed in a flotation position. The plurality of connection structure forms a retaining engagement that at least partially secures the garment assembly to the individual. The inflation assembly may dispose the inflatable bladder into an expanded and a collapsed orientation. When respectively disposed in the flotation position and in the expanded orientation, the garment assembly and the inflatable bladder are cooperatively configured to provide flotation to the individual. The pocket structure may retain and permit operation of a communication device.

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 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.

An emergency alert assembly for alerting people to a drowning or other emergency near an individual wearing the apparatus includes a belt and an alert device attached to the belt. The alert device includes a balloon and a gas tank which selectively fills the balloon with gas that is less dense than air. When filled with the gas, the balloon moves out of the housing and serves to indicate a location of an emergency such as a drowning.

A floatation device for use by an individual in a body of water, comprising of an upper body covering and two fabric covered inflatable sleeve elements. The upper body covering contains multiple gussets that hide the male or female end of a clasp device. The fabric covered inflatable sleeves contain the opposite end of the clasp device which allow them to be securely fastened to the upper body covering in one or more locations.
