Abstract

L'invention concerne un radeau de sauvetage très sûr qui peut être fabriqué facilement dans une taille quelconque souhaitée à un coût faible. Le radeau (11) de sauvetage comporte un corps principal (12A) de radeau qui peut être dilaté en y introduisant un fluide comprimé. Le corps principal (12A) de radeau comporte des tubes (12) capables de former des parties creuses tandis qu'ils sont dilatés par l'introduction d'un fluide, les tubes (12) comportant une pluralité de tuyaux souples annulaires (121 à 12n) de petit diamètre susceptibles d'être dilatés par introduction d'un fluide et disposés longitudinalement de telle façon que les parties creuses (12c) soient alignées entre elles. Si un fluide comprimé est introduit dans les tuyaux souples annulaires (121 à 12n) de petit diamètre, les parties creuses (12c) présentant un grand diamètre sont formées de telle manière que les parties creuses (12c) de grand diamètre communiquent avec des ouvertures de grand diamètre des deux côtés et sur les côtés intérieurs. Les tubes (12) capables de former des parties creuses tandis qu'ils sont dilatés par l'introduction d'un fluide sont reliés en forme de tore pour raccorder les ouvertures de grand diamètre des deux côtés. Une entrée / sortie est formée dans une face de paroi latérale à une position située plus haut que la surface de l'eau. Un compartiment (R) de sauvetage est formé à l'intérieur des parties creuses de grand diamètre. Un élément (18) d'aide à l'embarquement est installé dans l'espace intérieur des tubes (12) en forme de tore capables de former des parties creuses tandis qu'ils sont dilatés par l'introduction d'un fluide.
