INFLATABLE SELF-RECOVERING RAFT Russian patent published in 2017 - IPC B63C9/04 

FIELD: transportation.

SUBSTANCE: inflatable self-recovering liferaft comprises a hull of a lower and an upper buoyancy chamber that are made in the form of tubular closed shells, an inflatable bottom, gas filling systems and two inflatable racks arranged at a distance parallel to each other. The inflatable racks are represented by inflatable tubular elements in the form of arches, which consist of sections. Each inflatable rack extends from one side of the raft hull to the other and up and outward from the raft hull perimeter at an angle from the perpendicular to the raft hull. The sections of each inflatable rack in the plan fit into a semi-circle whose center is at the intersection of the vertical symmetry axis and the upper tangent plane of the tubular shell of the upper buoyancy chamber.

EFFECT: raft design safety when returning from the inverted raft position to the working vertical one without human intervention.
