Abstract: Rescue and safety device, permitting the reversibility of a rescue raft, shelter (s)-tent (s), consists of an inflated grille provided with unlockable, spreadable and lockable openings, handles and safety belts. On this grille are fixed bags (11) containing membranes that expand into the shelter(s) (8) and the floor(s) (7). The whole is made to be removable, including the weight element, by a fastener system that is laid on two sides of a boat. The male fasteners are fixed to handles (4) and bags (11), the female fasteners are fixed on the rods and allow, if the raft expands inside out, it to be remounted in place.
