  • Patent number: 5297847
    Abstract: A fire-resistant seating component. In a first embodiment, seat backs and pans are equipped with an enclosure containing a fire-retardant material which can flow out of early-release openings in the enclosure. The enclosure comprises at least one meltable zone which causes dispensation of the fire-resistant material at a temperature which is below the ignition temperature of the seating component. The enclosure is located at the lower portion of either a seat pan, a seat back, or both, so that burning rubbish such as paper cups and similar flammable debris disposed under a seat can be extinguished by the fire-retardant material as it flows vertically downward into the space beneath the seat. In a second embodiment, interior spaces within a seating component are coated or filled with non-combustible material to reduce the transfer of heat and the spread of fire. Such material may completely occupy the interior space within the component, or the material may simply coat the interior surfaces of the component.

The neoprene foam must be so formulated that it also is capable of evolving at combustion temperature sufficient amount of water to efficiently cool the affected area. Normally, the latex from which the foam is prepared is formulated with a char promoter and a hydrated inorganic compound. Upholstered furniture of this invention passes a burning cigarette test and performs extremely well in the flame spread test.

    Abstract: A liquid filled cover for a mattress having horizontally disposed upper and lower sheets of a material having a low resistance to penetration by fire and hot objects capable of initiating fire joined at their outermost edges to form a leakproof enclosure. After filling the enclosure with a fire extinguishing liquid, the filled height of the cover is relatively small as compared to its length and breadth. The upper sheet contains a closure for adding or removing liquid and a plurality of symmetrically opposed depressions within the upper and lower sheets of the liquid filled cover provide desired shape and load supporting characteristics. A retaining means positions and retains the cover to the top surface of a mattress. The liquid filled cover when interposed between a mattress and a sleeping occupant provides protection and warning to the occupant when the cover is punctured by fire or hot objects, whereby the released liquid acts to suppress the fire and awake the occupant.
