BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an emergency descent system, or “EDS”. More particularly, this invention relates to an EDS that can be fully incorporated, both storage and during use, in the outerwear of a firefighter's gear, especially the coat and pants for the same. These lightweight, integral systems will be “available” any and every time thereby allowing its wearer to safely escape from the higher levels of a building, home or office in an atypical emergency. This invention uses flame resistant rope or cable for lowering each firefighting individual to affect a controlled descent from a higher to lower elevation.
2. Relevant Art
Descent control devices have been developed with the objective of lowering individuals (or objects) from a higher to lower elevation. Such devices have taken many forms and have utilized a variety of elements. Some are capable of providing a mechanical braking mechanism, such as a dead-man or panic control feature, when the device would be used for descent, escape, or rescue purposes.
Concerns with occupational safety have led to the development of mechanisms that enable a worker to lower himself from an elevated position such as a scaffold, crane, lift truck or platform in the event of an emergency. That equipment is, in some respects, similar to known fire escape devices, mountain climbing equipment, and military equipment.
One descent control device with a dead-man brake, in the form of a vertical cylindrical drum or capstan about which a rope is wound and a tapered slot through the drum for receiving and releasably gripping the rope, is shown in Varner et al. U.S. Pat. No. 4,883,146. That device includes plates on each end of a vertical cylindrical drum or capstan with apertures on each end plate through which the rope is threaded, then wound in two or more turns around the drum.
Tapered slots are well known for releasably fastening ropes, lines and cables. The use of cylindrical capstans for holding and providing a mechanical advantage for tightening ropes is also known. Likewise, a variety of fire escape devices utilize rope wound around a cylinder. See, for example, Budd U.S. Pat. No. 386,237; FitzGerald U.S. Pat. No. 536,866; Howe U.S. Pat. No. 771,251; Thuemer U.S. Pat. No. 946,588; Smith U.S. Pat. No. 1,115,603; Steffen U.S. Pat. No. 4,311,218; and Forrest U.S. Pat. Nos. 4,508,193 and 4,550,801.

SUMMARY OF THE INVENTION
It is the principal object of the present invention to provide an improved controlled descent system that can provide full body protection to all firefighter outerwear. A related object is to provide a full body EDS full body harness (i.e., both chest and legs) that can enable firemen and firewomen a fail-safe descent from the elevated levels of most any burning structure.
Firefighting personnel with an integral descent controller built into their protective gear at very little extra weight “cost”, can work better, more effectively knowing that should certain circumstances arise, they should more easily achieve a safe evacuation from the higher floors of a burning complex.
In accordance with the foregoing objects, the present invention incorporates into most any existing (or newly constructed) fire coat and pant combinations a full body harness consisting of a panel housing flame resistant rope or cable, a purposefully designed control descent rack in and through which that rope/cable is wound and a friction braking handle described in more detail below.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to the accompanying drawings, there is shown a first preferred embodiment of FEDS, or full body emergency descent system incorporated into the protective outerwear (gear) of a firefighter according to the present invention.
The accompanying drawings show one preferred embodiment of FireCoat FEDS complete and installed (at various stages) on a mannequin for wearing illustration purposes. It is important to note several unique aspects of this design. This is a Full Body Safety Harness fully integrated into a firefighter's coat/jacket and pants. This is not a safety waist belt only or a safety chest strap only (unlike some of those shown in the prior art). Rather, this is a Full Body Rappelling System with integrated 115 feet of stored line into a firefighter's clothing that allows for very quick donning and utilization that is a must for firefighters to react quickly to life threatening events. Current Bailout Bags contain only 50 feet of line. And they are bulky accessory on the outside of the firefighter's clothing that can catch on objects in an emergency situation. Worse, the individual firefighters must put such a bag ON before leaving the station or truck. The FEDS invention herein, by contrast, is always with them; it never has to be donned or separately put on over existing protective wear clothing or equipment.
Why is a Full Body Rappelling System important? In a word, SAFETY! Studies done by US Air Force in 1987, shown that a single chest safety strap can cause unconsciousness and possible death in approximately 5 minutes. A single waist safety strap can cause unconsciousness and possible death in less than 2 minutes, as well as invert the wearer since the upper bodies of most men are heavier than below their waists. If a harness consisting of an upper body section and connected waist system, it is still not considered a Full Body Safety Harness by ANSI Z359 Standards. These types of harness are outlawed by current OSHA Standards and cannot be used on the workplace.
Determined by the U.S. Air Force, a Full Body Safety harness has a much better survival time, i.e., from about 15 to 30 minutes. If a firefighter can quickly get to the ground in an emergency, he/she should be fine with any of the escape equipment. However, if that individual cannot reach the ground and is suspended for a prolonged time, from being in a higher building than his/her rope will reach, OR, if the device jams and suspends the firefighter for an extended amount of time, he/she may die before he can be safely extricated.
What makes it a “Full Body” system is the Leg Loops that attach to the Chest Section. To be a Full Body Safety Harness, it must have a chest section and 2 leg loops as recognized by ANSI Z359. If the harness has no leg loops or only one leg loop, the harness cannot be certified to ANSI Z359 standards. The Leg Loops must be an integrated part of the total Safety Harness. Their function is to help provide partial support for the overall bodies weight while suspended. Without the weight being distributed between the legs and chest of a suspended person, the person can become unconscious and possibly die very quickly due to Suspension Trauma's effect on the body.
The Leg Loops of the FEDS are integrated INTO the firefighter's pants, and are located between the Thermal Liner that is against the firefighter's skin and the outside Fire Resistant External Layer of clothing. This is the same for the Upper and Lower FEDS sections. This is very important! The integrated system of this invention never breaches the Thermal Liner, where heat would then be able to penetrate to the skin of the firefighter.
Both Upper and Lower Sections are located on the outside of the Thermal Liner and under the External Layer of the Fireman's coat and pants. Both Upper and Lower Sections of the FEDS exit from being located between the Thermal Liner and the External Layer through dedicated, minimal openings. They terminate in stored, covered pockets where immediate access and utilization is quick and with minimal effort in an emergency.
Also, if a firefighter is injured and is down and not able to walk, there is an Internal Integrated Drag Strap that cannot pull off of the clothing, because it loops around that individual's arms and shoulders and only tightens on the body the more you drag that person as needed. Such a Drag Strap is also hidden in the closed access flap located at the upper center back of the firefighter's coat/jacket, where a fellow firefighter can quickly locate the Drag Strap and pull his/her teammate to safety.
Should a firefighter be unconscious and need to be lowered from a rapidly increasing dangerous location that is being overrun by fire, this is a life-or-death situation that calls for extreme measures. A fellow firefighter can: quickly pull the FEDS' chest straps from the pockets of the unconscious firefighter, snap his/her attachment buckles together, attach the end of the harness' line to a secure location and roll the unconscious firefighter out of an open window to a lower, safety point.
The friction already placed on the line as it goes through the EDS Rack will allow the unconscious firefighter to survive the descent with minimal trauma to the body. The Integrated Brake Strap does NOT have to be deployed to slow the descent of the wearer for a survivable landing.
With many of the current descending devices, the wearer must be conscious and able to operate the device. These devices will not assist an unconscious firefighter, possibly forcing other extreme measures that will extremely injure or kill that individual. There is no other emergency descending devices like the FireCoat FEDS (Fullbody Emergency Descent System).
When referring to any numerical length, width or other number range herein, it should be noted that all such numbers are mostly representative of just one embodiment of FEDS (mostly as shown). Furthermore, any such range of numbers should expressly include each and every fraction or decimal between its stated minimum and maximum. For instance, any one component (strap, etc.) measuring from 1 to 3 inches in length should also specifically cover any strap measuring 1.1, 1.25 and 1.5 inches . . . and so on, up to about 2.75, 2.8 and 2.99 inches. The same applies for every other quantitative range herein. Now with respect to a first, fully working prototype, note the following particulars:

Because of its Kevlar friction brake, this invention can use technologically advanced, smaller diameter, lighter, yet stronger, flame resistant line. Particularly, the wearer/user does not have to grip the line and add friction for slowing his/her own descent. In known emergency descent systems, only ⅜″ line or larger may be used since the human hand cannot adequately grip a smaller line with sufficient force. By contrast, the preferred line for this unit can be as little as 3/16″ thick, much smaller than previously used lines, when using its EDS Rack specially designed for such lines.
Due to the smaller diameter and lighter weight of line used, much greater quantities/lengths of line can be stored allowing for safer firefighter escape from higher distances (but only when used with the Kevlar Friction Break and EDS Rack also described herein.

All Original Equipment Modifications for the Firecoat Feds are Complete
Lastly, consider the following preferred instructions for putting on a fitted FIRECOAT FEDS along with instruction on using the Emergency Descent System now added to the firefighter's coats and pants. Particularly:
- 1 Before closing the coat, attach the FireCoat FEDS Leg Straps to the Pants Leg Loops forming a Fullbody Harness. Lift the corner of the coat, remove the Leg Strap Male Buckle from the Coat Storage Buckle, peel back the Pant Pocket Flap and insert the Leg Strap Male Buckle into the Leg Loop Female Buckle inside the Leg Pocket. Snug the Leg Strap, place the free end of the strap into the pocket and replace Pocket Flap. Continue to buckle the coat front closed.
- 2 TO PERFORM AN EMERGENCY DESCENT FROM AN UNSAFE POSITION USING THE FIRECOAT FEDS, remove both Chest Strap ends from both Chest Pockets and connect the Cobra Buckle ends.
- 3 This places the Chest Strap with EDS, Line and Brake in front of the Fireman.
- 4 Attach the end of the Line to a firm anchor capable of withstanding the forces placed on it by the Fireman's weight while descending.
- 5 The Fireman can expose additional Line by backing up or by pulling Line from the stored position by shoving down on the Line between the Brake and EDS Rack and then letting it transition up thru the EDS Rack.
- 6 To start a descent, PLACE BOTH HANDS IN THE BRAKE HANDLE LOOP, GRIPPING IT TIGHTLY. TO SLOW OR STOP YOUR DESCENT FIRMLY PULL DOWN ON THE BRAKE HANDLE LOOP TOWARDS YOUR FEET.
- 7 To descend, YOU MUST REDUCE ENOUGH PRESSURE ON THE BRAKE TO ALLOW FOR THE LINE TO TRANSITION FROM THE STORAGE LOOPS AND UP OUT OF THE EDS RACK.
- 8 TO ACCESS THE DRAG STRAP LOOP, open the Outside Collar Slot on the back of the coat and pull out the Drag Loop from its stored position.
While certain illustrative embodiments have been shown in the drawings and described above in considerable detail, it should be understood that there is no intention to limit the invention to the specific forms disclosed.
