Inflatable unit

Abstract

The present invention relates to an inflatable liferaft comprising at least one inflatable flotation tube, said inflatable tube extending circumferentially for providing a substantially ring-shaped area, and a bottom element which is adapted to provide a bottom to the substantially ring-shaped area. Furthermore, at least two seating arrangements are arranged in the ring-shaped area.

1 . An inflatable liferaft comprising at least one inflatable flotation tube, said inflatable tube extending circumferentially for providing a substantially ring-shaped area, and a bottom element which is adapted to provide a bottom to the substantially ring-shaped area, wherein at least two seating arrangements are arranged in the ring-shaped area. 
     
     
         2 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements are extending in a direction away from the inflatable tube across the ring-shaped area. 
     
     
         3 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements are inflatable. 
     
     
         4 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements are extending so that persons being evacuated are able to be seated on each side of the seating arrangements thereby using each other as backrest. 
     
     
         5 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements comprise at least three longitudinal parts, said longitudinal parts are extending substantially in a same plane. 
     
     
         6 . The inflatable liferaft according to  claim 5 , wherein the longitudinal parts are separate parts mutually connected or one unit comprising longitudinal parts. 
     
     
         7 . The inflatable liferaft according to  claim 5 , wherein longitudinal grooves are arranged between the longitudinal parts. 
     
     
         8 . The inflatable liferaft according to  claim 1 , wherein a plurality of seating arrangements are arranged parallel to each other across the ring-shaped area, with a predetermined distance between them. 
     
     
         9 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements are connected to the bottom element and/or the inflatable tube. 
     
     
         10 . The inflatable liferaft according to  claim 9 , wherein the seating arrangements are detachable or securely connected to the bottom element and/or the inflatable tube. 
     
     
         11 . The inflatable liferaft according to  claim 1 , wherein one or more passage(s) is/are arranged transversely to the extensions of the seating arrangements. 
     
     
         12 . The inflatable liferaft according to  claim 1 , wherein the seating arrangements are stiffening the liferaft in a transverse direction. 
     
     
         13 . The inflatable liferaft according to  claim 1 , wherein at least one of the seating arrangements are hingedly connected to the bottom element.
