Abstract: The present invention relates to a buoyant body surfing suit for a body surfer having knees. The buoyant body surfing suit includes an upper portion together with a pair of short sleeves, a collar, a front, and a rear being a homogeneous piece of resilient material, and a lower portion together with the upper portion and a front being a homogeneous piece of resilient material, the lower portion together with a pair of legs being a homogeneous piece of resilient material that ends below the knees of the body surfer so that due to the collar and the pair of short sleeves water is prevented from entering under the buoyant body surfing suit and slow down the speed of the body surfer.

Abstract: An individual rescue apparatus for use around the waist of a person comprising a waist encircling support belt (1) with a Fastener (2a,2b) at its extremities, an inflation system (9-14) adapted to be secured to the support belt, a pressurized gas reservoir adapted to be able to be placed in communication with the inflation system, and a release device adapted to assure the inflation of the system from the gas reservoir, the inflation system comprising a atubular portion (9) extending along the support belt and connected to the gas reservoir, and cells (11-14) distributed along the tubular portion and communicating therewith for inflating the cells by the action of the release device, the support belt (1) comprising an upward extension (3) of a height adapted to extend approximately above the center of gravity of the person when the belt is worn around the waist, the extension (3) being provided with an attaching zone (3a) in its upper portion, the inflation system (9-14) being maintained, in the passive posit

Abstract: A lined life-jacket comprises an airtight inflatable bag extending along the front and along the area of the neck and shoulders, a device for supplying compressed air into the airtight bag and an inflation tube. The compressed air supply device and the inflation tube are so arranged on the life-jacket that a person wearing the life-jacket can easily operate the device by hand and easily place the tube in the wearer's mouth.

Abstract: An improved personal floatation device composed of (a) a back panel to encircle the back and sides of a wearer, (b) a front panel and (c) a shoulder panel with a head opening which interconnects the front and back panel, and (d) straps for fastening the device about the body of a wearer and wherein the device includes a head support panel swingably connected to the top of the back panel for supporting the head of a wearer when worn by a user in water.

Abstract: A personal flotation device includes a back portion of buoyant material and a separate mesh layer between the back portion and the wearer of the personal flotation device for increasing the comfort of the personal flotation device. The mesh layer and the buoyant material are connected together at the top and bottom and are unconnected along at least a portion of the sides, and the length of the mesh layer is less than the length of the buoyant material so that the buoyant material buckles outwardly away from the wearer.

Abstract: There is disclosed an underwater jacket including an outside waterproof cloth and an inside waterproof cloth, said outside and inside cloths being put one upon the other and connected together at their marginal edges by sewing to form a jacket body into which air can be injected. The outside and inside cloths are partially connected to each other by high-frequency welding at a portion or portions where the cloths are to be folded or curved during use. At least one hole is formed through the outside and inside cloths at the portion, and a bolt made of plastic material is passed through the hole, while a nut made of plastic material is fitted to a protruding end of the bolt on the other side of the cloths. Packings are interposed between the bolt and nut and the outside and inside cloths, respectively.

Abstract: A combined life vest device and buoyancy compensator is disclosed for use by divers along with scuba gear including a back pack for mounting a compressed air tank on the back of the diver. One embodiment of the invention comprises a single garment for the diver including inner and outer shells providing abrasion protection with first and second airtight chambers forming respectively a buoyancy compensator adjacent the compressed air tank and a part of life vest surrounding the diver's torso. A conventional power inflator is employed for regulating pressure within the buoyancy compensator. An inflating device for the second chamber preferably includes an interconnection between the two chambers with a one-way check valve so that the second chamber is automatically inflated when pressure in the first chamber exceeds a predetermined level. A rebreathing tube is provided in communication with the second chamber so that the diver may use it as an emergency air supply.

Abstract: A swim-safe play suit is provided and consists of a plurality of substantially equi-spaced flexible waterproof buoyant elements arranged within upper portion of the play suit in parallel relation so that if wearer of the play suit enters water the wearer will not drown.

Abstract: A combined swimming aid and lifesaving device in which a buoyant harness for encircling the swimmer's torso comprises a plurality of releasably interconnected portions for selective use of one or more parts of the harness to obtain desired buoyancy, and a plurality of separate inflatable buoyant devices are releasably attached to the harness at spaced locations thereon to impart greater or lesser buoyancy to the device for providing desired buoyant support to the swimmer to maintain the swimmer in horizontal position in the water. Attaching points are on the harness for securing a lifeline thereto, and the inflatable buoyant devices remain slack when inflated so that they are able to undulate during use to reduce drag through the water.
