Fire-resistant mattress and high strength fire-retardant composite
First Claim
1. In a mattress comprising a cover and a plurality of flammable components, a composite comprising a first layer of a fire-retardant composition bonded to a second layer of a material having a high tensile strength in the directions along its surface, the composite substantially enclosing the flammable components and oriented such that the material having a high tensile strength is disposed adjacent to at least one of the flammable components and the fire-retardant composition is disposed adjacent to the cover.

Abstract
An improved mattress includes a composite made of a layer of a fire retardant material capable of providing a heat barrier bonded to a layer of high tensile strength material, such as fiberglass fabric. The composite encloses at least most and generally practically all of the flammable ingredients of the mattress. When exposed to a fire, the fire retardant material chars, thereby creating a heat shield that protects the inside of the mattress while the high tensile strength material holds the mattress together and prevents the mattress from bursting open thereby exposing the flammable ingredients thereof to the fire.
The composite of the present invention is made by bonding a fire-retardant material capable of providing a heat barrier to a high tensile strength material.

6. In a mattress, the improvement comprising:
a composite layer enclosing substantially all of the flammable components of said mattress, said composite layer comprising a first layer of a fire retardant composition bonded to a second layer of a material having high tensile strength in directions along its surface, said first layer of said composite layer charring upon being exposed to fire to protect the inside of said mattress from heat and fire and said second layer preventing the mattress from bursting open upon being exposed to fire. - View Dependent Claims (7, 8, 9, 10)
