developments of the invention can be found in the 30 dependent claims.
The arrangement of the gas generator in the floatation bag means that the physical volume of the module is smaller than in the case of separate, externally 35 located, arrangement. In addition, it is simple to pack the floatation bag immediately adjacent to the gas generator, and this has the advantage that the gas generator inflates the floatation bag directly, without any flow losses. The gas losses resulting from flow
drag and cooling are thus small. The floatation bag has a bag flap to simplify installation of the gas generator. The bag flap is located where the tensile stresses on the floatation bag are at their smallest. One major advantage of the invention is that the module floats freely but constrained by means of the cable after it has been inflated and disconnected from the watercraft, without any risk of any functional adverse effect on the module or the vessel's own devices or other modules.
One exemplary embodiment of the invention is illustrated in the drawing, in which:
Figure 1 shows a side view of an inflated floatation bag, and
Figure 2 shows a front view of the floatation bag as shown in Figure 1.
A bearing foot 7 is firmly connected to the mounting plate 5 via a separating bolt 9, which can be initiated pyrotechnically, on a mounting plate 5, which is on the inner wall 1 of a watercraft 3.
A wound-up cable 13 is stored in a cavity 11 in the bearing foot 7, alongside the separating bolt 9. The cable 13 is connected to the mounting plate 5 and to the bearing foot 7.
A cylindrical pin 17 of a retaining body 19 is located in a further cavity 15 in the bearing foot 7.
A cylindrical gas generator 23 is mounted in a cylindrical, thin-walled trough 21 with vanes 20 on the retaining body 19, over an area 53.
A packaging bag 25 surrounds both a folded-up floatation bag 27, which is mounted on the gas
generator 23, and the gas generator 23, which is arranged in it. The packaging bag 25 is attached to the base body 7 in a gastight and watertight manner underneath a widened section 31.
In the area 55 of the lowest tensile stresses, the floatation bag 27 has openings 50 which can be closed in a watertight and gastight manner by means of a flap 49 on the floatation bag 27, for mounting of the gas generator 23 and of the retaining body 19. The flap 49 overlaps the base bag 47 and is connected to it at 51 in a gastight and watertight manner.
A weatherstrip 35 for the floatation bag 27 is mounted in a recess ¾33. The recess 33 is formed by appropriate channels 37, 38 on the bearing foot 7 and on the retaining body 19.

Operating ^sequence :
The gas generator 23 is initiated electrically in order to displace .. the water in the interior 2. The folded floatationAbag 27, which is still located within the packaging bag 25, starts to fill with gas, with the gas emerging at an opening 41 for the gas generator 23, and entering the floatation bag 27 directly and immediately.
Finally, the increase in gas volume in the floatation bag 27 bursts the packaging bag 25, and the floatation bag 27 unfolds to its final size, as shown. The water is correspondingly displaced, and the buoyancy is produced by the filled floatation bag 27.
After about 0.2 seconds, the separating bolt 9 is initiated electrically, and releases the bearing foot 7. The floatation bag 27, together with the gas generator 23, the retaining body 19 and the bearing
'"' foot 7, moves away by virtue of its buoyancy as far as the length of the cable 13 from the inner wall 1, and ' tries to find space for itself in the interior 2.
. One significant factor for the attachment of the floatation bag is that, beyond the weatherstrip 35, the floatation bag 27 is guided by the outer surface 22 of the vanes 20 on the partially cylindrical trough 21 - Figure 2. Fluctuations in the floatation bag 27 or
. extreme changes in the position of the floatation bag 27 do not lead to any kinking on the floatation bag 27. There are no shear stresses on the floatation bag 27. The cylindrical gas generator τ see Figure 1 - as well as the radii 43, 45 on the gas generator 23 also 5 contribute to this, on a plane offset through 90°.
; It is also advantageous for gaps 61 which are filled with gas to be formed between the cylindrical gas generator 23 and the floatation bag 27. These gaps 61 0 form additional buoyancy volume.
