The invention relates to an improved escape system including a chute adapted to compensate for varying vertical distance. Elastic cords extend in a course of direction which progresses differently from vertically when the escape system has been launched and the chute is hanging vertically from the higher position to the lower position, such that tension is applied to the elastic cords. By the present invention it is realised that a longer elongation of the chute may be obtained without increasing the minimum length when the elastic cords extend in such a course of direction, because the cords hereby become longer than in a course of direction progressing straight and vertically. Since any elastic cord has a maximum strain which it may safely endure, a longer extent of such a cord subjected to maximum strain will result in a longer elongation, and hence longer maximum length while maintaining or even reducing the minimum length. One effect is therefore that the ability of the escape system to compensate for varying evacuation height is improved.
