Abstract

An elevator car with special measures for evacuation has several side walls, a floor and a ceiling, which together enclose an interior of the elevator car. The elevator car has a flap arranged on one of the side walls and a ladder for evacuating persons from the interior of the elevator car. The flap is movable between a closed state, in which the flap blocks access from the interior of the elevator car to an area behind the flap, and an open state, in which access is possible from the interior of the elevator car to the area behind the flap. The flap has a height less than the height of the side walls. In the closed state of the flap, the ladder is arranged in the area behind the flap. The ladder is removable from behind the flap and can be increased in length for the evacuation.
