1. An inflatable unit for evacuation purposes, comprising:
- at least a first inflatable chamber and a second inflatable chamber, said chambers abutting each other;
an opening, which is arranged between the two inflatable chambers;
a pressure source with an inflating gas, which pressure source is connected to the first inflatable chamber;
a one-way valve, which is arranged in connection with the opening between the inflatable chambers so that the inflating gas can only pass from the first chamber to the second chamber, wherein the one-way valve comprises;
at least a first sheet, which is made of a flexible material, said first sheet being adapted to be a sleeve or be part of a sleeve, said sleeve having a first end and a second end, and at least openings at both ends, said sleeve being substantially closed between the ends, said sleeve being directly or indirectly connected at the first end to an outer side of the first chamber around the opening so that an airtight passage for the inflating gas is created inside the sleeve.

Abstract
The present invention relates to an inflatable unit for evacuation purposes, said inflatable unit comprising at least a first inflatable chamber (1) and a second inflatable chamber (2), said chambers abutting each other, an opening, which is arranged between the two inflatable chambers (1, 2), a pressure source with an inflating gas, which pressure source is connected to the first inflatable chamber (1), a one-way valve (3), which is arranged in connection with the opening between the inflatable chambers, so that the inflating gas only can pass from the first chamber (1) to the second chamber (2). The one-way valve (3) comprises at least a first sheet (4), which is made of a flexible material, said first sheet (4) being adapted to be a sleeve (5) or be part of a sleeve (5). Furthermore, the sleeve (5) has a first end (7) and a second end (8), and at least openings (9, 10) at both ends (7, 8), said sleeve (5) being substantially closed between the ends (7, 8). The sleeve (5) is directly or indirectly connected at the first end (7) to an outer side (6) of the first chamber (1) around the opening so that an airtight passage for the inflating gas is created inside the sleeve (5).
