Abstract
A slit curtain separating apparatus for separating a smoking area and a non-smoking area, defined in a passenger cabin of an airliner, with respect to cigarette smoke includes a curtain wall, which is suspended from the ceiling of the passenger cabin and extends along the boundary between the smoking and non-smoking areas. The curtain wall has slit curtains arranged individually over left- and right-hand aisles of the passenger cabin and a center curtain located between the aisles. The separating apparatus further includes a vent port array on the ceiling of the smoking area. The vent port array has aisle vent ports corresponding individually to the aisle and a center vent port located between the aisles. Smoke filled air in the smoking area is discharged from these vent ports.
