CA 2533810

A survival suit (10) including two inner bladders (50), (60) filled with air exhaled from the user to provide warmth and floatation. The first inner bladder (50) is located against the user~s back that covers the entire dorsal region. Located behind the firs inner bladder (50) is a second inner bladder (60) that acts as an insulation layer when submerged under water. Both the first and second inner bladders (50), (60) are filled with fibrous filler material (80) to provide insulation and allow exhaled air to flow freely therein. An air conduit (74) extends from the user~s mouth to the second inner bladder (60). Formed between the first and second inner bladders (50), (60) is an air passageway (55) that delivers air from the second inner bladder (60) into the first inner bladder (50). Air outlet ports (58) located on the first inner bladder (50) allows exhaled air to escape into the body cavity (14) and that completely surround the user. The exhaled air in the body cavity (14) eventually escapes through the face opening (23).

La présente invention concerne une combinaison de survie (10) qui comprend deux sacs gonflables internes (50), (60) remplis par l'air exhalé par l'utilisateur, qui fournit chaleur et flottaison. Le premier sac gonflable interne (50) est situé contre le dos de l'utilisateur et couvre toute la région dorsale. Derrière le premier sac gonflable interne (50) est situé un second sac gonflable interne (60) qui agit comme une couche isolante lorsqu'il est immergé dans l'eau. Le premier et le second sac gonflable interne (50), (60) sont remplis d'une matière de charge fibreuse (80) qui assure l'isolation et permet à l'air exhalé de circuler librement à l'intérieur. Une conduite d'air (74) s'étend de la bouche de l'utilisateur au second sac gonflable (60). Un passage d'air (55) est formé entre le premier et le second sac gonflable (50), (60), qui distribue l'air du second sac gonflable interne (60) au premier sac gonflable interne (50). Des orifices de sortie d'air (58) situés sur le premier sac gonflable interne (50) permettent à l'air exhalé de s'échapper dans la cavité corporelle (14) qui entoure complètement l'utilisateur. L'air exhalé dans la cavité corporelle (14) s'échappe finalement à travers l'ouverture faciale (23).
