CA 2262559

A liferaft has a floor (52) surrounded by one or more inflatable tubes (50, 51). Two canopies (54a, 54b) are provided, one (54a) covering one side of the floor (52) and the other (54b) covering the other side of the floor (52). When the liferaft is deployed on water, support means, which may be an inflatable column (63), erect the canopy (54a) that is above the water. The other canopy (54b) is unerected and lies in the water. The system of weights (67) and elastic ropes (66) forms the canopy in the water into stabilizing means in the form of water pockets. Similar means are provided on the deployed canopy (54a) but, when the canopy (54a) is erected, they lie flush with the canopy surface and so do not interfere with the operation of the liferaft.

Radeau de sauvetage possédant une base (52) entourée par un ou plusieurs tubes gonflables (50, 51). Ce radeau comporte deux auvents (54a, 54b), l'un (54a) recouvrant un côté de la base (52) et l'autre (54b) recouvrant l'autre côté de la base (52). Quand le radeau de sauvetage est déployé sur l'eau, des moyens de support, pouvant être constitués par une colonne gonflable (63), dressent l'auvent afin qu'il soit au-dessus de l'eau. L'autre auvent (54b) n'est pas dressé et repose dans l'eau. Un système de poids (67) et de cordes élastiques (66) font de l'auvent reposant dans l'eau un dispositif de stabilisation sous forme de poches d'eau. L'auvent déployé (54a) possède des moyens semblables mais, quand cet auvent (54a) est dressé, ces moyens sont alignés sur la surface de l'auvent et ne jouent, par conséquent, aucun rôle dans l'opération du radeau de sauvetage.
