Emergency safe haven

Abstract

An emergency safe haven for use in hazardous environments is claimed. The safe have has a compacted and expanded shape. When expanded, the safe haven provides a volume for crewmembers to occupy in times of emergency. The safe haven has an air supply for providing the occupant with breathable air.

1 . An emergency safe haven comprising: 
 a crew compartment having an internal volume, a compacted shape, an expanded shape, and a crew compartment closure cooperating with a crew compartment access port;    the crew compartment closure having an open position and a closed position and the closed position covering the access port in a substantially airtight manner;    an anteroom having an internal volume, a compacted shape, an expanded shape, and an anteroom closure cooperating with an anteroom access port;    the anteroom closure having an open position and a closed position and the closed position covering the access port in a substantially airtight manner;    the crew compartment being fixedly attached with the anteroom;    an air supply;    the crew compartment and anteroom being transitioned from an initially compacted shape to an expanded shape and in the expanded shape a crew member gains access to the anteroom internal volume through the anteroom access port when the anteroom closure is in the open position and a crew member gains access to the crew compartment internal volume from the anteroom through the crew compartment access port when the crew compartment closure is in the open position; and    the air supply providing air for the crew members in the anteroom and the crew compartment when the anteroom and the crew compartment are in the expanded shape.    
   
   
       2 . An emergency safe haven as in  claim 1  wherein the crew compartment further comprises; 
 a fabric outer shell; and    an air barrier inner shell.    
   
   
       3 . An emergency safe haven as in  claim 1  wherein the anteroom further comprises; 
 a fabric outer shell; and    an air barrier inner shell.    
   
   
       4 . An emergency safe haven as in  claim 1  further comprising; 
 a pressurized gas reservoir;    a gas reservoir valve; and    the pressurized gas reservoir being connected to the gas reservoir valve and the pressurized gas reservoir valve communicating with the crew compartment and the anteroom such that the activation of the gas reservoir valve releases gas from the pressurized gas reservoir and inflates the crew compartment and the anteroom from the compacted shape to the expanded shape.    
   
   
       5 . An emergency safe haven as in  claim 1  further comprising a food source.  
   
   
       6 . An emergency safe haven as in  claim 1  further comprising a water source.  
   
   
       7 . An emergency safe haven comprising: 
 a crew compartment having a compacted shape and an expanded shape and the crew compartment comprising; 
 i) a fabric outer shell;  
 ii) an air barrier inner shell;  
 iii) an internal volume formed by the air barrier inner shell;  
 iv) a crew compartment access port extending through the air barrier inner shell and the fabric outer shell;  
 v) a crew compartment closure having an open position and a closed position and the closed position covering the access port in a substantially airtight manner;  
   an anteroom having a compacted shape and an expanded shape and the anteroom comprising; 
 i) a fabric outer shell;  
 ii) an air barrier inner shell;  
 iii) an internal volume formed by the air barrier inner shell;  
 iv) an anteroom access port extending through the air barrier inner shell and the fabric outer shell;  
 v) an anteroom closure having an open position and a closed position and the closed position covering the access port in a substantially airtight manner;  
   the crew compartment being fixedly attached to the anteroom;    a pressurized gas reservoir;    a gas reservoir valve;    an air supply;    the pressurized gas reservoir being connected to the gas reservoir valve and the pressurized gas reservoir valve communicating with the crew compartment and the anteroom such that the activation of the gas reservoir valve releases gas from the pressurized gas reservoir and inflates the crew compartment and the anteroom from the compacted shape to the expanded shape;    in the expanded shape, a crew member gaining access to the internal volume of the anteroom through the anteroom access port with the anteroom closure in the open position and thereafter the anteroom closure is transitioned to the closed position;    the crew member gaining access to the internal volume of the crew compartment from the anteroom by moving through the crew compartment access port with the crew compartment closure in the open position and thereafter the crew compartment closure is transitioned to the closed position; and    the air supply providing air for occupants of the crew compartment and the air supply providing pressure such that the pressure in the anteroom and the crew compartment is substantially at the same pressure when the closures are in the closed position.    
   
   
       8 . A method for using an emergency safe haven comprising the steps of: 
 inflating a crew compartment and an anteroom;    accessing the anteroom through a closure;    accessing the crew compartment from the anteroom through a closure; and    activating an air supply for providing air to the anteroom and the crew compartment.    
   
   
       9 . An emergency safe haven comprising: 
 a crew compartment having a compacted shape, an expanded shape, and a substantially airtight crew compartment closure;    an anteroom having a compacted shape, an expanded shape, and a substantially airtight anteroom closure;    the crew compartment being fixedly attached with the anteroom;    an air supply connected to the anteroom and the crew compartment;    means for transitioning the crew compartment and anteroom from an initially compacted shape to an expanded shape;    means for a crewmember gaining access to the anteroom through the anteroom closure;    means for a crewmember gaining access to the crew compartment from the anteroom through the crew compartment closure; and    means for utilizing the air supply for providing air for the occupants of the anteroom and the crew compartment when the anteroom and the crew compartment are in the expanded shape.    
   
   
       10 . An emergency safe haven comprising: 
 a crew compartment fixedly attached to an anteroom and the crew compartment and anteroom having a compacted shape and an expanded shape;    means for transitioning the crew compartment and anteroom from a compacted shape to an expanded shape;    means for a person to gain access to the anteroom;    means for a person to gain access to the crew compartment from the anteroom; and    means for providing air to the crew compartment and the anteroom.
