The life jacket has a harness designed to be fitted over the torso of an individual and having a dorsal structure and a ventral structure, at least ventral buoyancy tubes attached to the harness, and manual inflation means for inflating the ventral buoyancy tubes. The uninflated ventral buoyancy tubes are arranged in the dorsal structure of the harness and, when inflated, they are deployed in the ventral structure of the harness. The harness has a guide rope extending along its dorsal and ventral structures and the ventral buoyancy tubes are attached to the harness by a connector that can also be inflated and is designed to be deployed, under the action of the inflation means, by being guided along the guide rope. The life jacket is only deployed on the front of the abdomen in the event of difficulty.

An autonomous lifebuoy includes a body, an electric power supply, a propelling module and a control unit configured to control the autonomous lifebuoy so as to automatically guide the autonomous lifebuoy towards a person overboard in water, during a man overboard (MOB) situation. The control unit includes at least one communication module, a non-volatile memory, a graphics processing unit (GPU) configured to perform an image comparison and a microcomputer configured to make calculations, based on at least the image comparison performed by the graphics processing unit (GPU), and issue commands to at least the propelling module to propel the autonomous lifebuoy towards the person overboard in the water during the man overboard (MOB) situation.

A signal device for maritime distress rescue and a surveillance device for maritime distress rescue are provided. The signal device for maritime distress rescue which is carried by a user aboard a vessel may include a first communicator configured to communicate with a surveillance device for maritime distress rescue of the vessel, a first position detector configured to generate first position information of the signal device at a predetermined time interval, and a first controller configured to receive second position information of the surveillance device from the surveillance device at a predetermined time interval and determine whether the first position information is within a safe area of the vessel that is set on the basis of the second position information. Accordingly, when a distress occurs, it is possible to transmit a distress signal without operating a switch while minimizing power consumption of the signal device.

A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve.

A personal flotation assembly is provided that includes flotation device and a protective shell extending therefrom. The flotation device is a buoyant structure that includes an open interior, such as a ring or similar shape. Along the lower end of the flotation device is a protective shell. The shell includes a spiral expansion spring therein and a resilient construction, whereby the shell is adapted to compress against the flotation device when stored and expand outward when deployed. When deployed, the shell forms a rounded sidewall, an enclosed lower, and an interior volume sized to receive the floating user. The shell is made of a resilient material and is water permeable. Therefore, the flotation assembly supports a floating user and protects the user when adrift for long periods. Additional locating elements may be secured to the floatation device, including strobes or signal generators.

A plastic internally hollow body has a cavity for containing liquids, solids or gases, and includes a main body shaped and having an inner surface at least partially defining the cavity. The inner surface terminates in a shaped edge that delimits a coupling aperture to the cavity. The internally hollow body includes a closure body, having an outer sealing surface suitable at least partially engaging the inner surface of the main body. The closure body at least partially closes the cavity in correspondence of the coupling aperture. The main body is joined to the closure body at least partially along the shaped edge by a joining element over-moulded to the main body and the closure body and covering the over-moulding seat resulting between the main body and the closure body. A method for making the internally hollow body over-moulds the joining element by injection moulding with an over-moulding mould.
