Abstract:
1. An escape system for emergency evacuation from a first higher position to a second lower position comprising a chute, said chute comprising: a plurality of spaced apart shaping sections defining a longitudinal axis, each shaping section including at least one ring-like structure; a plurality of elastic cords for connecting said plurality of shaping sections, said elastic cords having a cord coupling at an intermediate section thereof, said plurality of elastic cords being connected to the shaping sections in positions along a circumference of the ring-like structures, wherein said plurality of elastic cords are configured to allow relative motion between shaping sections in a direction generally parallel to the longitudinal axis of shaping sections; at least one tunnel-like device arranged and held inside the plurality of shaping sections and configured to enable a person who is being evacuated to move from the first position to the second position through the tunnel-like device; and a plurality of length limiting means, each length limiting means having one end connected directly to at least one of the ring-like structure and another end having means for releasably connecting directly to the cord coupling, said length limiting means providing the chute with a self adjusting length so as to be operable at least at two different mean chute lengths when the chute has been launched and the chute is hanging substantially vertically from the higher position to the lower position.
