Abstract:
A parachute is stored within the specially configured seat back of each passenger seat of a commercial aircraft, behind a removable front upholstery panel. The parachute harness extends outwardly from the concealed parachute, through and beyond the periphery of the removable panel, for donning by the seated passenger. An openable upper cover extends over the top of the concealed parachute. When the parachute is needed, the passenger (having previously donned the parachute harness) pulls forward from the seat to release the front upholstery panel from the seat back to pull the parachute free, and escapes from the aircraft. In the event the seat structure separates from the aircraft, the still seated passenger opens the top flap of the seat back to access the parachute rip cord. A second embodiment comprises a child harness having a series of D-rings thereon, for face-to-face attachment to the parachute harness of an accompanying adult.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to passenger protection and safety systems for airline aircraft, and more specifically to an individual parachute system for each passenger seat on an airline aircraft. The present invention generally comprises an individual parachute removably installed within a cavity formed in the seat back of each passenger seat aboard an airline aircraft. The parachute harness extends forwardly from the seat back for donning by the seated passenger. 
     2. Description of the Related Art 
     While airline safety has seen continuous improvement over the years, the airline industry cannot provide one hundred percent safety to its passengers. Any time a complex machine is traveling at a high rate of speed, there is some element of danger, even if that element is quite small. While various safety devices have been installed in airline aircraft in the past, and in fact are required by regulation (e.g., flotation devices for overwater flights, and emergency oxygen equipment), there has never been any requirement for emergency parachute equipment to be provided on board for airline passengers. 
     In the past, most parachutes tended to be relatively bulky and heavy, and the placement of emergency parachutes within the passenger cabin of an airliner was impractical, due to the reduction of payload and interior cabin volume. However, the parachute industry has seen significant advances in emergency parachutes in the relatively recent past. Many emergency parachutes are now capable of supporting persons of significant weight and withstanding opening shocks at relatively high velocities, all while conforming to a back pack configuration having a thickness of only three inches or so, and a weight of less than fifteen pounds. 
     The configuration of the modern emergency parachute lends itself to convenient storage within the seat back of an otherwise conventional airline passenger seat, with the seat back modified to provide a cavity or receptacle for such an emergency parachute. Accordingly, the present invention provides such an airline seat configuration, with an emergency parachute stored within the modified seat back structure for ready removal and deployment as needed. The forward panel of the seat back upholstery is removably secured over the parachute, with the parachute harness extending forwardly from the seat back for the passenger to don for potential emergency use. The present invention also provides a child harness which removably attaches to the front of the seat back parachute harness, enabling infants or small children to escape with their parent or guardian. While successful escape from an airliner may be difficult, the present invention at least opens the door for possible survival in an otherwise likely fatal accident. 
     A discussion of the related art of which the present inventor is aware, and its differences and distinctions from the present invention, is provided below. 
     U.S. Pat. No. 3,436,037 issued on Apr. 1, 1969 to Robert M. Stanley, titled “Apparatus For Deploying And Opening Parachutes,” describes an emergency parachute using a small rocket to deploy the chute. The rocket is jettisoned from the parachute pack, and then ignited to pull the parachute from the pack. The Stanley parachute deployment device is primarily directed to military chutes which are generally worn directly upon the back of the pilot, rather than to an emergency parachute which is stored within a cavity in a seat back structure, as is the case with the present invention. 
     U.S. Pat. No. 3,516,098 issued on Jun. 23, 1970 to Maurice H. O&#39;Link, titled “Floatable Life Preserver Seat Insert,” describes is a buoyant cushion which is removable from the bottom of the seat structure. The cushion serves as a seat cushion during normal use, but is easily and quickly removed for use as a float in the event of a water emergency landing. No parachute is disclosed, either in the bottom or the back of the seat. 
     U.S. Pat. No. 3,726,499 issued on Apr. 10, 1973 to Fred B. Stencel, titled “Method Of Deploying A Parachute By A Rocket Under Low Speed Conditions,” describes another ejection seat system, utilizing a rocket to deploy an emergency parachute from a seat back structure. The parachute remains attached to the seat structure, rather than being removed from the structure, as in the present airline seat parachute invention. 
     U.S. Pat. No. 3,862,731 issued on Jan. 28, 1975 to Robert G. McIntyre, titled “Zero-Delay Speed/Altitude Controlled Ejection Seat,” describes a system which bypasses or overrides the normal parachute opening delay system, to cause the parachute to deploy more rapidly in the event of low altitude and/or low airspeed use. The present airline seat parachute system may make use of automated devices for opening the parachute, as disclosed in the McIntyre &#39;731 U.S. Patent, which disclosure is incorporated herein by reference. While McIntyre discloses a parachute which is automatically deployed when the ejection seat separates from the flight crewmember, the parachute is worn on the back of the flight crewmember, rather than being stored within the seat back. 
     U.S. Pat. No. 4,004,764 issued on Jan. 25, 1977 to Vernon D. Burklund et al., titled “Drogue Chute Extraction,” describes yet another ejection seat mechanism using a rocket to deploy a drogue chute, which in turn deploys the main parachute. The main chute remains affixed to the seat structure, unlike the present airline seat parachute which separates from the seat back for use. 
     U.S. Pat. No. 4,306,748 issued on Dec. 22, 1981 to Kenneth Sullivan, titled “Life Jacket Installation,” describes a life jacket which is stored in the bottom and back of a seat, with the assembly primarily intended for use in a hovercraft or other high speed watercraft, rather than in an airliner. Accordingly, no parachute is disclosed by Sullivan, and the overall life jacket apparatus of Sullivan is considerably bulkier than is suitable for placement only within the seat back. 
     U.S. Pat. No. 4,527,758 issued on Jul. 9, 1985 to Peter Ayoub et al., titled “Deployment Sequence Mode Selection System For Aircraft Ejection Seat,” describes an electronic system which takes into account the airspeed, altitude, and rate of descent of the ejection seat and its flight crewmember, to determine the optimum deployment of the parachute. No parachute or seat structure is disclosed by Ayoub et al. 
     U.S. Pat. No. 4,619,623 issued on Oct. 28, 1986 to Bernt Elverskog, titled “Life-Jacket Assembly,” describes an emergency use device stored in an aircraft seat back assembly. The Elverskog life jacket is deployed by opening the top cover for the seat back; the front cover for the seat back is permanently attached to the seat back structure. Elverskog does not disclose separation of the front cover of the seat back from the remainder of the seat back structure, nor capture of that front cover between a parachute (or any other emergency device) and the person wearing or using the parachute, as provided by the present invention. Also, Elverskog does not provide any means for a complete six point harness to be secured from his device to the person using the device, through the permanently affixed front panel of the seat back upholstery. 
     U.S. Pat. No. 4,709,885 issued on Dec. 1, 1987 to James W. Martin, titled “Parachute System And Aircraft Ejection Seat Incorporating The Same,” describes a seat mounted drogue and main parachute system, closely resembling the system of the Stencel &#39;499 U.S. Patent discussed further above. The same points of difference noted in that discussion, are seen to apply here as well. 
     U.S. Pat. No. 4,765,570 issued on Aug. 23, 1988 to Gerald F. Herndon, titled “Aircraft Ejected Seat Stabilizing And Delayed Parachute System,” describes a system wherein the parachute harness is attached directly to the flight crewmember, but which utilizes an ejection seat to remove the flight crewmember and his parachute from the aircraft. The parachute is not stored within any part of the seat, but rather is donned by the flight crewmember before being seated in the ejection seat. Accordingly, no separable panel securing a parachute within the back of a seat structure, is disclosed by Herndon. 
     U.S. Pat. No. 4,775,119 issued on Oct. 4, 1988 to Armand J. Aronne, titled “Aircraft Crew Multipurpose, Unitary Backpack For Bailout And Survival,” describes a backpack assembly worn by the flight crewmember, with the assembly containing a parachute and additional survival gear. The flight crewmember wears the assembly while seated in the aircraft, but the assembly remains with the crewmember at all times in the aircraft, rather than being secured within the seat back structure and concealed behind the front panel of the seat back upholstery, as in the present invention. 
     U.S. Pat. No. 4,865,273 issued on Sep. 12, 1989 to Leon Jones, titled “Parachute-Release Mechanism And Method,” describes an aneroid device for automatically deploying a parachute at a predetermined altitude. The present emergency parachute system may include such a device as well, with the disclosure of the Jones &#39;273 U.S. Patent being incorporated herein by reference. 
     U.S. Pat. No. 5,213,392 issued on May 25, 1993 to John M. Bostrom, titled “Seat Construction,” describes a seat back with an open area between the two side bolsters. A housing extends rearwardly from the seat back, to provide room for a large oxygen cylinder. The Bostrom seat is intended for firefighters who require such supplemental breathing apparatus, and is not suitable for the comfort of a passenger in a vehicle. Bostrom does not disclose any form of parachute with his seat, nor any form of front surface upholstery cover overlying the seat back structure to secure a parachute therein, as provided by the present invention. 
     U.S. Pat. No. 5,342,109 issued on Aug. 30, 1994 to David L. Berry et al., titled “Seat Having Life Jacket Contained Therein,” describes a seat back structure having a hollowed central area for a life jacket. The front of the seat back has an openable upholstery panel using Velcro® for securing along three sides, but having its upper edge permanently secured to the forward side of the seat back, just below the conventional headrest. In order to remove the life jacket from the Berry et al. seat back, the front upholstery panel must be lifted upwardly and back over the headrest. This is unworkable with the present invention, for two reasons: (1) the passenger would be unable to escape while wearing the parachute harness with the seat back upholstery captured between the parachute and passenger, as the Berry et al. upholstery panel is permanently affixed to the seat back at the headrest; and (2) folding the Berry et al. upholstery panel over the headrest, would preclude access to the top of the chute and rip cord D-ring. 
     U.S. Pat. No. 5,825,667 issued on Oct. 20, 1998 to Eric Van Den Brock, titled “Parachute Release Device,” describes an automated parachute opening device, which senses acceleration to determine a maximum velocity of a falling person and cause the chute to open before that velocity is exceeded. The Van Den Brock device incorporates an aneroid pressure sensor to provide altitude information, as well as other sensors. The Van Den Brock device is intended for use by sport parachutists, rather than as an emergency device per se. Accordingly, Van Den Brock does not disclose any form of seating in which a parachute is stored for emergency use, as provided by the present invention. However, the present emergency parachute system may make use of an aneroid device to provide for automatic opening of the chute, as noted further above. 
     U.S. Pat. No. 5,979,829 issued on Nov. 9, 1999 to Nell W. Nance et al., titled “In-Flight Evacuation System,” describes a system in which each passenger seat has a parachute and survival kit in the seat back portion. In an emergency, the seats rotate 180 degrees and move along tracks to a rear exit. The seat back separates from the seat bottom, with the bottom remaining with the aircraft and the back remaining with the passenger, who descends using the parachute deploying from the seat back. The present invention contrasts by leaving the relatively bulky seat back behind, and requires little, if any, modification to the airframe itself. However, Nance et al. disclose the general structure of a conventional passenger carrying commercial aircraft in their &#39;829 U.S. Patent, which disclosure is incorporated herein by reference. 
     British Patent Publication No. 640,520 published on Jul. 19, 1950 to James Martin of Martin-Baker Aircraft Company, titled “An Ejection Seat For Aircraft,” describes an early pyrotechnically actuated ejection seat. The only parachute mechanism incorporated with the seat per se, is a relatively small drogue chute which deploys immediately after ejection. The primary parachute is worn by the flight crewmember at all times, and is not stored or contained within the seat back prior to use, as it is in the present invention. 
     British Patent Publication No. 2,118,498 published on Nov. 2, 1983 to Autoflug GmbH, titled “Air-Sea Rescue Apparatus,” describes an automated actuation system for operating components of a survival system after an emergency bailout. Most of the elements of the survival system are located in the bottom of the seat. No seat back structure is disclosed, either conventionally or having a parachute contained therein. 
     Finally, PCT Patent Publication No. 00/56,600 published on Sep. 28, 2000 to Simula, Inc., titled “Adjustable Emergency Ejection Seat,” describes a seat mechanism having vertical and fore-aft adjustment. No parachute system nor space for housing a parachute in the seat back structure, is disclosed in the PCT Patent Publication. 
     None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant invention as claimed. Thus an airline seat parachute solving the aforementioned problems is desired. 
     SUMMARY OF THE INVENTION 
     The present invention comprises two embodiments of a passenger parachute system for use with airline or other commercial aircraft. In a first embodiment, the seat back of each passenger seat has a receptacle therein, in which an emergency parachute is stored during normal operations. The parachute harness extends forwardly from the seat back, between the edge of the removable front upholstery panel and the remainder of the seat back structure, for donning by the seated passenger. The front upholstery panel of the seat back, which conceals and protects the emergency chute during normal operations, is secured to the periphery of the seat back by removable fastener means, e.g., Velcro®. The top of the seat back and emergency parachute are covered by a separate flap, which remains permanently attached to the seat back along its rearward edge. However, the forward and lateral edges of the flap are removably attached (e.g., Velcro®, etc.) respectively to the removable front upholstery panel and top edges of the seat back. 
     When the emergency chute is needed, the passenger need only pull away from the seat with the chute harness secured around the passenger, to pull away the removable front upholstery panel of the seat back and parachute from the seat back structure. The removable upholstery panel remains captured between the passenger and the parachute. In the event that the seat structure separates from the aircraft in its entirety, the passenger need only open the upper flap to access the rip cord handle, with deployment of the parachute causing the remainder of the seat back to pull away. 
     A second embodiment comprises a smaller six point harness, adapted for use by infants and small children who are otherwise not seated within individual passenger seats within the aircraft. This child harness is not equipped with a parachute, but includes a series of sturdy fasteners (e.g., D-rings or the like) which are permanently secured to the front of the harness. An adult parent or guardian passes his or her harness through the D-rings of the child harness, to secure the child to the adult in a face-to-face relationship. The relatively light weight of the child will not significantly increase the descent rate of the adult in his or her parachute. 
     Accordingly, it is a principal object of the invention to provide an airline seat parachute system, with an emergency parachute contained within the seat back structure of each passenger seat of an airliner or other commercial aircraft. 
     It is another object of the invention to conceal such an emergency parachute within the seat back structure, by means of a removably installed front upholstery panel for the seat back which covers the emergency parachute therein and which allows the harness of the parachute to extend therefrom for donning by a passenger seated within the seat. 
     It is a further object of the invention to provide such an emergency parachute system which provides rapid access to the rip cord of the parachute, even though the parachute remains in its stored location within the seat back, for actuation by the passenger in the event the seat separates from the aircraft. 
     Still another object of the invention is to provide a child harness which is removably attachable to the adult harness. 
     It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. 
     These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention comprises two embodiments of an emergency escape system for passengers of a passenger carrying, commercial aircraft. A first embodiment of the present invention is illustrated in FIGS. 1 through 4 of the drawings, and comprises an emergency parachute  10  which is removably installed within a parachute receptacle  12  within the seat back portion  14  of an airline passenger seat assembly  16 . A second embodiment is illustrated in FIG. 4 of the drawings, and comprises a child&#39;s harness which may be removably secured to the harness assembly  18  of the emergency parachute  10  of FIGS. 1 through 4. 
     FIG. 1 illustrates a typical airline passenger seating row  20 , with each of the seat assemblies  16  comprising the seat row  20  having a seat back portion  14  containing an emergency parachute  10  within a parachute receptacle  12  therein. Each of the emergency parachutes  10  includes a conventional six point harness assembly  18 , comprising a pair of shoulder straps  22 , a lateral chest strap  24 , left and right leg straps  26  and  28 , and a conventional waist strap (not shown, for clarity in the drawing FIGS.). The seat back portions  14  are each covered with a removable front upholstery panel  30 , with each parachute  10  proper being protected and concealed behind the corresponding upholstery panel  30 , and with the various straps  22  through  28  extending forwardly from the edges of the upholstery panel  30  where they are accessible for donning by a passenger seated within any of the seats  16 . 
     FIG. 3 of the drawings provides an illustration of the partially removed front upholstery panel  30  of the seat back  14 , with a separate openable upper panel  32  being shown lifted from the upper or headrest portion  34  of the seat back structure  14  to access the parachute  10 . The periphery of the upper seat back structure  34  includes a lower edge  36  which joins the main seat back structure  14 , an opposite upper edge  38 , and opposed left and right lateral edges  40  and  42 . The upper seat back structure  34  is covered by an openable panel  32 , as noted above, with the panel  32  having a periphery comprising a lower edge  44 , an opposite upper edge  46 , and opposed left and right lateral edges  48  and  50 . The left and right lateral edges of the upper seat back structure  34  and openable upper panel  32 , i.e., upper seat back/panel edges  40 / 48  and  42 / 50 , are congruent and overlap one another. 
     The upper or rearward edge  46  of the openable panel  32  is permanently secured (e.g., stitched, etc.) to the corresponding upper edge  38  of the upper seat back portion  34 , with the forwardmost or lower edge  44  (when closed over the upper seat back portion  34 ) being congruent with and overlapping the upper edge of the removable front upholstery panel  30  of the seat back structure  14 , as explained further below. The various openable edges  44 ,  48 , and  50  of the openable panel  32  include removable fastening means  52  thereon, e.g., first hook and loop fastening material (Velcro®) with the corresponding lateral edges  40  and  42  of the upper seat back structure  34  and mating upper edge of the front upholstery panel  30  having mating second material  54  thereon. 
     The primary portion of the seat back structure  14 , below the upper or headrest portion  34 , has a periphery defined by an upper edge  56 , an opposite lower edge  58 , and opposed left and right lateral edges  60  and  62 , with the emergency parachute receptacle  12  being contained within these peripheral edges  56  through  62  and with the upper portion of the parachute  10  extending upwardly into the upper seat back portion  34  as required. The periphery of the removable front upholstery panel  30  is defined by an upper edge  64 , an opposite lower edge  66 , and opposed left and right edges  68  and  70 . As in the case of the upper seat back portion  34  of the seat back structure  14 , and its openable upper cover  32 , the periphery of the seat back structure  14 , comprising edges  56  through  62 , and the periphery of the removable front panel  30  of the seat back structure  14 , comprising edges  64  through  70 , are congruent with one another, with the removable panel edges  64  through  70  overlapping the corresponding edges  56  through  62  of the seat back structure  14 . 
     As in the case of the upper seat back portion  34  and its cover  32 , the edges  58  through  62  of the seat back structure  14 , and lower edge  44  of the openable cover  32 , have a first type of separable fastener material  72  disposed thereon, which removably engages a mating second type of fastener material  74  disposed upon the edges  64  through  70  of the removable front panel  30  of the seat back structure  14 . The mating first and second fastener material  72  and  74  is preferably hook and loop material (e.g., Velcro®), although other fasteners (snaps, etc.) may be used as desired. 
     The hook and loop fastener material  72  disposed along the sides  60  and  62  and bottom edge  58  of the main seat back structure  14 , faces forwardly so as to engage the rearwardly facing mating material  74  along the sides  68  and  70  and lower edge  66  of the removable seat back upholstery panel  30 . However, the fastener material  74  along the upper edge  64  of the removable panel  30  faces forwardly when the panel  30  is in place, as shown by the upturned right hand corner of the panel  30  in FIG.  3 . This allows the rearwardly facing and mating fastener material  52  installed along the rearwardly facing lower edge  44  of the openable upper cover  32 , to overlap the upper edge  64  of the lower panel  30  and engage the mating fastener material  74  to provide a complete seal around the enclosed parachute  10  within the seat back structure  14 , excepting the areas where the various harness straps  18 ,  26 ,  28 , etc. extend from between the upholstery panel  30  and seat back structure  14  edges, and/or between the upper edge  64  of the removable panel  30  and overlapping lower edge  44  of the openable upper cover  32 . 
     The parachute  10  is readied for potential use by opening the upper cover  32  and removing the seat back upholstery panel  30  from the seat back structure  14 , and placing the parachute  10  within the seat back receptacle  12 . All harness buckles and closures are opened at this time, with the various harness straps  22 ,  26 ,  28 , etc. extended from the parachute receptacle  12 . The removable cover  30  is then reinstalled over the parachute  10 , and the upper cover folded downwardly and attached along its edges to the upper seat back structure  34  and upper edge  64  of the removable cover  30 . 
     When the passenger boards, he or she need only secure the parachute harness  18  about his/her body, and rest assured that an emergency escape from the aircraft is possible using the parachute  10 . (A woman wearing a dress or skirt may forgo securing the leg straps  26  and  28  until they are needed.) In the event that evacuation is necessary from the aircraft in flight, the passenger need only release his/her conventional seat belt (not shown in the drawings, for clarity) and pull forward from the seat, thereby pulling the removable fastener material apart which holds the removable upholstery panel  30  to the seat back structure  14 , and which holds the openable upper cover  32  in place. Alternatively, the passenger may manually separate the various fasteners  52 ,  54  and  72 ,  74 , if so desired. The removable upholstery panel  30  remains captured between the back of the passenger and the parachute  10 , as the parachute  10  and upholstery panel  30  are pulled from the seat back structure  14 . 
     It will be noted in FIG. 3 that the rip cord handle  76  extends from the upper portion  78  of the parachute  10 , rather than its more conventional location near the center of the harness  18 . In the event of a catastrophic structural failure, where the seat(s)  16  and/or seat row(s)  20  are torn from the aircraft, the passenger may still be saved by the present invention. In such an event, if the passenger is still conscious and able to respond, he/she need only unfasten his/her seat belt, open the upper panel  32 , and pull the rip cord handle  76  extending from the upper portion  78  of the parachute  10 . 
     The opening shock of the parachute  10  will likely separate the parachute  10  from the remainder of the seat structure  16 , causing the releasable fastener material along the edges of the removable panel  30  to separate from the seat structure  16 , just as if the passenger separated him or herself from the seat structure  16  while still in the aircraft. However, it is likely in such a catastrophic accident that the passenger would be rendered unconscious, and unable to open his/her parachute  10 . Accordingly, a conventional automatic opening device (aneroid, etc.) may be included with the parachute  10 , to assure that the chute  10  will open as required without manual intervention. Such devices are well known in the art, with disclosures of such devices noted further above in the discussion of the related art, and incorporated herein by reference. 
     FIG. 4 of the drawings illustrates a further embodiment of the present invention, comprising a child harness  80  which is devoid of any parachute attachment per se. Federal Aviation Regulations and most airline rules, allow infants, toddlers, and small children who may be seated or carried upon the lap of a parent or guardian, to be carried in such a manner, rather than being required to have their own seat. Such a small child would thus not have access to the seat mounted parachute and harness of the present invention. In any event, the harness  18  of the seat stored emergency parachute  10  of the present invention, would not likely provide sufficient adjustment to fit a very small child or toddler. 
     Accordingly, a child harness  80  is provided, which removably attaches to the parachute harness  18  of the emergency parachute  10  of the present invention. The child harness  80  is preferably a smaller version of a conventional six point harness, including a pair of front and rear straps  82 ,  84  which pass generally vertically over the shoulders and between the legs, with the two straps  82  and  84  being secured together laterally by upper and lower lateral back straps  86  and  88 . A pair of left leg straps  90  and right leg straps  92  complete the harness assembly  80 . The child harness  80  does not include a parachute, but rather includes a series of removable fasteners (e.g., D-rings  94 , etc.) extending from the front straps  82  and  84 , which may be removably secured to the parachute harness  18 . 
     The child harness  80  is secured to the primary parachute harness  18  by opening the two vertical front or shoulder straps  22  of the harness  18 , and passing the ends through the appropriate D-rings  94  of the child harness  80 , once the child has been secured within the harness  80 . The child is secured in a face-to-face relationship with the adult wearing the parachute  10  and its harness  18 , to provide a more comforting relationship. The relatively light weight of a infant, toddler, or very small child, produces a negligible increase in the sink rate of the emergency parachute  10 , thus allowing the parachute  10  to save both lives, if at all possible. 
     In conclusion, the present airline seat parachute, along with its additional embodiment including a child harness which is removably attachable to the primary parachute harness, provides a response to many potentially disastrous situations in aviation. While the present invention may not be able to save a significant number of lives in many aviation disasters where extremely high altitudes and speeds are involved, the potential for saving even a few lives under the right circumstances, serves to justify the present invention. While the present invention is directed primarily to commercial airline passengers, it may also be adapted for use by flight and cabin crewmembers as well, and may find even more practicable use in lighter commercial charter and air taxi aircraft. The present airline seat parachute will not only provide some potential for saving lives, but will greatly enhance the peace of mind of passengers flying in aircraft so equipped. 
     It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
