The escape device is lowered via a cable which can be anchored above and outside a window of a burning building. The descent of the device is regulated by a speed regulating brake or by a valve mounted in a hydraulic line for manual operation by the user. A guide device for the cable is connected to a rigid seat on which the occupant would be seated while descending along a burning building. A pair of wheels are also provided at a lower end of the seat to space the seat from the building and to provide stability while descending along the height of the building. In another embodiment, a sling is suspended from the guide device in order to receive the occupants with the seat regulating brake and emergency brake located in an overhead manner. In another embodiment, a hydraulic energy absorber controls the unwinding of the cable from a reel mounted under the seat of the device.
