The device comprises at least one pair of flexible ballasts which extend laterally along the length of the inflatable structure and each comprise an orifice, acting as a vent, situated at the front, and a scoop system situated at the rear. Between the ballasts, at least one pipe connects the cavities of said ballasts to equalize their level of fill and the stagnation pressure of the water obtaining in said cavities when the inflatable structure is pulled along in the inflated state. This scoop system consists of a component moulded in a rigid or semirigid thermoplastic or is made of an assembly of cutouts from a flexible material of watertight fabric. This scoop system is bonded and/or welded to the ballast.

The rescue device for the passengers and crew of a ship includes: a container that contains survival equipment; a system that is intended for stowing said container relative to the deck of the ship and contains at least one strap and a system for multimodally attaching and releasing said container; an airbag-type inflatable balloon set up between a structure, secured to the deck, and said container, said structure defining a passage for the passengers when needed; and a means for releasing the airbag set up on the wheelhouse of said ship. The frame-shaped structure is formed of: two side posts; a lower cradle, on which said container rests; an upper crosspiece; and a plate set up inside the ship and acting as a counterbearing for the airbag when said container is ejected.
The device comprises at least one pair of flexible ballasts (3) which extend laterally along the length of the inflatable structure (1) and each comprise an orifice (6), acting as a vent, situated at the front, and a scoop system (4) situated at the rear with, between these ballasts, at least one pipe (5) which connects the cavities of said ballasts (3) to equalize their level of fill and the stagnation pressure of the water obtaining in said cavities when the inflatable structure is pulled along in the inflated state. This scoop system (4) either consists of a component moulded in a rigid or semirigid thermoplastic or is made of an assembly of cutouts from a flexible material of the watertight fabric type, and this scoop system is bonded and/or welded to the ballast (3).
B63B 1/14 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving lift mainly from water displacement with multiple hulls the hulls being interconnected resiliently
The rescue device for the passengers and crew of a ship includes: a container (10) that contains survival equipment; a system that is intended for stowing said container (10) relative to the deck of the ship and contains at least one strap (14) and a system for multimodally attaching and releasing said container (10); an airbag-type inflatable balloon (30) set up between a structure (11), secured to the deck (9), and said container (10), said structure defining a passage for the passengers when needed; and a means for releasing the airbag (30) set up on the wheelhouse of said ship. The frame-shaped structure (11) is formed of: two side posts (12); a lower cradle (13), on which said container (10) rests; an upper crosspiece (23); and a plate (26) set up inside the ship and acting as a counterbearing for the airbag when said container (10) is ejected.
The invention relates to a ramp (1) that includes three longitudinal beams (5, 6) each including at least two inflatable tubes (8) braced by inflatable tubes of side and lower struts arranged as closed stiffening inflatable frames (11, 18) having a polygon shape at the inflated state and surrounding the longitudinal beams (5, 6) to which the tubes of the stiffening frames (11, 18) are connected by connection means and inflation means.
A sea survival device (1) comprising a container (2) with several shells (3, 4) enclosing respective pneumatic liferafts (5, 6) in the deflated and folded-up state, and inflation means; one half-shell (4) enclosing a liferaft (6) is closed by a closure partition (7); the automatically triggered inflation means are operationally associated with at least the first liferaft (5) in a manner such that said first liferaft (5) is inflated first when the survival device (1) is deployed operationally; and the liferaft (6) is operationally associated with inflation trigger means suitable for trigging inflation thereof only once the first liferaft (5) is inflated.
