Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 60/443,973, filed Jan. 31, 2003.[0001]

BACKGROUND OF THE INVENTION

This invention relates generally to fire safety products and methods, and more particularly to methods and systems for deploying a blanket usable for protection against fire and heat within a vehicle.

Commercial airline passenger safety continues to be paramount in the minds of industry professionals and passengers. The increase in the number of both domestic and international flights has led to a potential increase in accidents. Airplanes present a significant danger of fire after a technically survivable crash. In most accidents, passenger injuries may arise from three basic threats including impact, fire, and heat.

In the event of a potential crash landing, passengers are instructed to fasten their seat belts and tuck into a crash position. Although seat belts reduce the threat of injury from impact and tucking reduces the threat of injury from dislodged debris, the passengers are substantially unprotected against fire and heat. A passenger seat-based system that provides each passenger with the means to shield themselves against fire and heat would be beneficial.

BRIEF DESCRIPTION OF THE INVENTION

In one aspect, a blanket usable for protection against fire within a vehicle wherein the blanket is stored within the vehicle is provided. The blanket includes a first layer having a flame resistant material, a second layer having a heat resistant material adjacent the first layer, a fastener having a flame resistant material configured to attach the first layer to the second layer, and a cushion usable within the vehicle wherein the cushion includes a sealable cavity for storing the blanket in a deployable position. The first layer and the second layer form a thin, flexible, sheet-like blanket having a length and a width dimension larger than a thickness dimension.

In another aspect, a cushion attachable to a seat is provided. The cushion includes a sealable cavity, and a blanket usable for protection against fire wherein the blanket is configured to be stored in the sealable cavity in a deployable position. The blanket includes a first layer having a flame resistant material, a second layer having a heat resistant material adjacent to the first layer, and a fastener having a flame resistant material configured to attach the first layer to the second layer. The first layer and the second layer form a thin, flexible, sheet-like blanket having a length and a width dimension larger than a thickness dimension.

In another aspect, a fire emergency protection system usable within a vehicle is provided. The system includes a seat having a headrest for a passenger within the vehicle, a cushion attached to the headrest having a sealable cavity, and a blanket usable by the passenger for protection against fire within the vehicle. The blanket is foldable for storage within the sealable cavity and for facilitating deployment around the passenger.

In another aspect, a method of deploying a fire emergency protection system usable within a vehicle is provided. The method includes providing a cushion attachable to a headrest on a seat within the vehicle wherein the cushion has a cavity configured to store a blanket usable for protection against fire within the vehicle, enabling a passenger to easily access the blanket within the cavity in case of a fire emergency, and deploying the blanket from the cavity using a first and a second strap such that the blanket covers the passenger within the seat.

FIG. 4 is a bottom view of [0034] emergency blanket 10 shown in FIG. 1. Blanket 10 is a thin, flexible sheet such that it is foldable. In the example embodiment, blanket 10 can be folded along a series of lengthwise folds 60. Each fold 60 has a width 62. In the exemplary embodiment, fold width 62 is approximately seven inches wide. Fold width 62 is dependant upon the size of blanket 10 and the vehicle seat (not shown in FIGS. 1-3). Each of blanket edge 36 and 38 are folded in a first direction 64 towards center axis 40. Blanket 10 is folded until a distance 66 exists between center axis 40 and fold 60. In the exemplary embodiment, distance 66 is 7.5 inches.
FIG. 5 is front perspective view of an [0035] airplane seat 70 and headrest 71 and emergency blanket 10 prior to storage in headrest 71. FIG. 6 is front perspective view of the airplane seat with the emergency blanket stored therein. Blanket 10 is folded as shown in FIG. 4 until blanket 10 resembles the folded blanket 10 in FIG. 5. Blanket 10 is then folded in a series of accordion-like folds 72. Each fold 72 has a width 74. In the exemplary embodiment, fold width 74 is approximately seven inches wide.
During storage, [0036] blanket 10 is disposed within a cushion 80 that includes a cavity 82. Cavity 82 is sized to receive blanket 10 and is configured to secure blanket second end 32 to an attachment member 84. Blanket 10 is fixedly attached within cavity 82 using a mechanical fastener (not shown), including, but not limited to, a thread or a metallic grommet. A protective flap 86 allows blanket 10 to remain covered while in cavity 82. A first end 88 of protective flap 86 is fixedly attached to headrest 71 using a mechanical fastener (not shown), including, but not limited to, a thread or a metallic grommet. A second end 90 of protective flap 86 is releasably attached to headrest 71 using a mechanical fastener (not shown), including, but not limited to, hook and pile fasteners.
FIGS. [0037] 7A-7F are front perspective views of airplane seat 70 with emergency blanket 10 being deployed by a passenger 100. Beginning with FIG. 7A, passenger 100 is notified of a potentially dangerous situation. Passenger 100 lifts protective flap 86 up and back in a direction 102 toward the rear of the airplane (not shown) exposing first and second straps 44 and 46. Next in FIG. 7B, passenger 100 grasps first and second straps 44 and 46 and pulls in a vertical direction 104 by extending their arms a length 106 until blanket 10 extends from seat 70. In FIG. 7C, passenger begins to pull blanket 10 in a second horizontal direction 108 and blanket 10 begins to unfold. In FIG. 7D, passenger 100 pulls blanket 10 in a downward direct 110 and then grabs third strap 48 and pulls in a downward and sideways direction 112 using both arms. In FIG. 7E, passenger 100 secures first and second straps under their feet. In FIG. 7F, passenger 100 pulls third strap 48 until the entire passenger is covered by blanket 10.
The flame resistant side of blanket protects the passenger from flames that may occur at or shortly after impact, while the heat resistant side protects the passenger from the heat generated by the flames. In one embodiment, the blanket can be detachably connected to headrest such that it can be removed while the passenger exits the plane. Additionally, the blanket has uses outside vehicles that take advantage of both its accordion-like folding nature and its fire and heat protection. In one embodiment, high rise buildings could place cushions within an office such that a person trapped by a fire in the office could deploy the blanket as a shield to assist in exiting the building, therefore eliminating the need to jump from the building and yet maintain access to fresh air. [0038]
The blanket's ability to provide protection from fire and heat and its ability to be stored in small cavities will facilitate reducing deaths and injuries resulting from fire emergencies that occur within vehicles including airplanes, motor vehicles, and trains. [0039]
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims. [0040]
