<p>The invention relates to a device for increasing the buoyancy of a human body in water. The device comprising, an inflatable tube member (1), a coupling unit (4) comprising a first part (8) and a second part (11), said coupling unit (4) together with said tube member (1) being arranged to form an endless float ring when the device is in the active state, a gas cartridge (6) comprising a punctureable membrane, a penetration element (23) arranged to puncture said membrane, a gas duct extending between said first part (8) of the coupling unit (4) and the tube member (1), wherein the gas cartridge (6) and the penetration element (23) are mutually displaceable in the direction towards each other. The device is characterized in that a first coupling member (20) of the first part (8) is pivotally arranged about a pivot between an inactive position and an actuating position, in which the first coupling member (20), direct or indirect, causing said mutual displacement of the gas cartridge (6) and the penetration element (23).</p> |
