ABSTRACT:
Safety enclosures for use in high speed vehicles such as aircraft and high speed trains. The safety enclosures include an enclosure shell which preferably has two shell walls separated by a crash resistant intermediate material which also provides thermal insulation against fires and acoustic attenuation. The enclosures also advantageously include cooling systems which utilize a refrigerant which is expanded through tubes connected along the inner wall of the enclosure shell. A compressed air supply is provided which supplies breathing air to passengers and is used to expand a crash bag. Air is supplied through both the crash bag at passenger contacting panels and through supply lines which exhaust near the passengers' heads. A motor driven door assembly is controlled to close as the crash bag is being deployed. Exhaust ports having check valves allow positive pressure to be maintained in the cabin of the enclosures to exclude smoke and fire. Passenger seating is provided which includes a dual shoulder harness restraint which is supplemented by the crash bag system. Seating includes a number of features designed to reduce shock and inertial forces experienced by the passengers during crashes. The safety enclosures are provided in singular units and modular arrays having single rows and opposing muliple rows of passenger seats.
