Abstract: The present invention relates to a life-jacket assembly primarily intended for aircraft passengers, including a buoyant body (7) furnishing at least the principal part of the buoyancy, and straps or the like adapted to retain the life-jacket assembly in position on persons in emergency situations, said buoyant body (7) being utilized as upholstery in a chair or the like.The novel feature is that the life-jacket includes an elongated, generally flat buoyancy body (7) substantially made of buoyancy material, that the life-jacket is entirely contained in an upwardly open compartment in the back-rest of a chair where the buoyant body (7) forms at least part of the upholstery, that an end surface of the life-jacket is provided with a pull handle (6) which is accessible at the top end of the back-rest, and that the generally flat body (7) has, at some distance from that end which is provided with the pull handle, an opening (8) through which the user has to pass his head.
Abstract: The rescue-unit includes a housing containing, a folded floating element and a bottle of compressed gas for automatic inflation of the floating element in the water. Inflation is initiated as soon as disc-like support-elements, placed on edge, become soft and buckle, when water enters, and thus no longer prevent actuation of a valve loaded by a spring located below the bottle of compressed gas. The spring can be completely released, for the purpose of actuating the valve of the compressed-gas bottle, only when a locking element, projecting into a preloading device loaded by the spring, is removed. The locking element is firmly connected to a retainer in which the housing is secured. When the housing is withdrawn from the retainer, the preloading device is automatically unlocked, leaving the rescue-unit ready for automatic inflation of the floating element as soon as the water gains access to the support-elements.
Abstract: There is disclosed a cold-proof water-proof garment, which is to be worn for marine operations on cold water and can save life in such a case as when a man wearing it accidentally drops into water or encounters perils of the sea.
Abstract: A dual chamber personal flotation device which allows rebreathing into it. One of the chambers is for flotation only and is inflated with CO.sub.2 ; the other is for rebreathing, and is inflated with air. A tube located close to the wearer's mouth has a combination mouthpiece-shutoff valve on it which is designed to collect a minimum amount of water in it prior to being inserted in the wearer's mouth, thereby minimizing problems due to water ingestion during rebreathing. The chambers are independently inflatable in the event that either the size or the buoyancy has to be minimized in order to escape.
Abstract: An inflatable life preserver of the encapsulated type encircling the neck of a wearer includes an inflatable cell or cells confined within a protective cover when in collapsed condition. The cover, formed of a strong fabric or other flexible material, comprises a pair of panels between which the cell is confined. The panels are premanently secured along the edge of a neck-encircling, center opening of the cover. The outer edges of the panels are separably connected, to confine the collapsed cells. Inflation of the cells causes separation of the panels. A protective flap is substantially coextensive in area and configuration with the panels, and lies between the panels so that the cover is in effect composed of three layers. The cells are confined between the flap and one of the panels, the flap being secured along its outer edge to said one panel while having its inner edge left free.
