Abstract:
1. An inflatable floatable unit for life-saving equipment comprising at least a first inflatable flotation tube layer having an upper and a lower side with a distance between the upper side and the lower side, a second inflatable flotation tube layer having an upper and a lower side with a distance between the upper and lower sides, the first and second flotation tube layers being adapted to be arranged substantially above each other so that the upper side of the first tube layer is opposite the lower side of the second tube layer, the inflatable tube layers extending circumferentially for providing a substantially ring-shaped area, and a bottom element adapted to provide a bottom to the substantially ring-shaped area, wherein the bottom element comprises a first bottom layer and a second bottom layer, both bottom layers substantially covering the entire ring-shaped area, the first bottom layer being connected with the inflatable unit between the first and second flotation tube layers, the second bottom layer being connected with the lower side of the first flotation tube layer, and both bottom layers being connected with each other at least at a centre point of the ring-shaped area, the first and second bottom layers having a mutual distance at the centre point being less than the distance between the upper and lower sides of the first flotation tube layer so that at least the second bottom layer has an inclined extension from the lower side of the first flotation tube layer to the centre point.
