Abstract: To save space it is often not possible to provide a comfortable seat beside a bed, for example for a second flightdeck crew. Normally, sitting on a bed is not comfortable for extended periods of time. The present invention states a backrest arrangement which can be changed from a foldaway position to a seating position. The backrest arrangement can be hinged to a wall. In foldaway position, the distance between a lower region of the backrest and the essentially vertical surface is shorter than in the seating position. In this way the backrest arrangement can for example be attached to a wall beside a bed; in the seating position the backrest arrangement provides a comfortable and safe seat.
