Aircraft passenger cabin area which comprises: - a main aisle which extends substantially parallel to a longitudinal axis of the aircraft passenger cabin area; - a restricted area, wherein a safety area is defined in a region of the restricted area; - a transverse aisle which connects the main aisle to the restricted area; - at least one passenger seat which comprises a rigid carrier structure, a backrest and a seat element and which is arranged in the passenger cabin area adjacent to the transverse aisle in such a way that the seat element faces towards the transverse aisle; and - a compressible object arrangement area disposed adjacent to the safety area and, when viewed in a direction substantially parallel to a longitudinal axis of the transverse aisle towards the restricted area, protruding into the restricted area, wherein the safety area may not be encroached by components installed within the aircraft passenger cabin area, but in the compressible object arrangement area a compressible object which, by the application of a pressure, can be reduced in size may be arranged, wherein the seat element is displaceable, relative to the backrest and the carrier structure, wherein the seat element comprises a compressible seat cushion forming a seating surface, the seat element is substantially linear displaceable in a direction substantially perpendicular to the longitudinal axis of the transverse aisle between a usable position and an out-of-use position, in the usable position of the seat element, the seating surface has a first depth by the compressible seat cushion protruding from the compressible object arrangement area into the safety area defined in the region of the restricted area, and in the out-of-use position of the seat element, the seating surface has a second depth smaller than the first depth by the compressible seat cushion clearing the safety area defined in the region of the restricted area by being entirely arranged within the compressible object arrangement area. - a main aisle which extends substantially parallel to a longitudinal axis of the aircraft passenger cabin area; - a restricted area, wherein a safety area is defined in a region of the restricted area; - a transverse aisle which connects the main aisle to the restricted area; - at least one passenger seat which comprises a rigid carrier structure, a backrest and a seat element and which is arranged in the passenger cabin area adjacent to the transverse aisle in such a way that the seat element faces towards the transverse aisle; and - a compressible object arrangement area disposed adjacent to the safety area and, when viewed in a direction substantially parallel to a longitudinal axis of the transverse aisle towards the restricted area, protruding into the restricted area, wherein the safety area may not be encroached by components installed within the aircraft passenger cabin area, but in the compressible object arrangement area a compressible object which, by the application of a pressure, can be reduced in size may be arranged, wherein the seat element is displaceable, relative to the backrest and the carrier structure, wherein the seat element comprises a compressible seat cushion forming a seating surface, the seat element is substantially linear displaceable in a direction substantially perpendicular to the longitudinal axis of the transverse aisle between a usable position and an out-of-use position, in the usable position of the seat element, the seating surface has a first depth by the compressible seat cushion protruding from the compressible object arrangement area into the safety area defined in the region of the restricted area, and in the out-of-use position of the seat element, the seating surface has a second depth smaller than the first depth by the compressible seat cushion clearing the safety area defined in the region of the restricted area by being entirely arranged within the compressible object arrangement area.
