Abstract

An emergency descent system includes at least one ladder which is articulated on at least one supporting unit on a bearing device. The ladder is designed to be unfolded about this bearing device out of a rest position in which the ladder is disposed parallel to the at least one supporting unit and into a working position, wherein a push-out unit and a pivot unit operatively connected thereto by means of a catch are associated with the ladder. The pivot unit drives the push-out unit by the kinetic energy generated during the unfolding, wherein the push-out unit moves away from the at least one supporting unit at a first acute angle, and in the operating position, the push-out unit forms an acute angle with the at least one supporting unit and the pivot unit is held at an obtuse angle relative to the push-out unit on a stop associated with the at least one supporting unit.
