Abstract

Corner guards suitable for use with a bedding assembly and providing a degree of fire resistance. The corner guards may contain fire/flame resistant (FR) polymeric reagents, flammable polymeric reagents combined with one or more FR agent or have an FR coating. Additionally, the corner guards may have effective FR properties while substantially maintaining the mechanical properties that allow the corner guard to support and protect the edges of upholstered furniture, such as a foundation or sofa. The corner guards arise, at least in part, from the realization that flare ups occurring during the test about the combustion of an FR foundation, result from high burn temperatures causing the corner guard to melt and the subsequently combustion of the melted polymeric material.

Description

200924672 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The field of the invention relates to furniture and in particular to fire corner protectors for mattress, seat and bedding assemblies. In particular, it relates to the application and manufacture of fire corner protectors for bedding assemblies. [Prior Art] Today, the mattress industry is taking steps to make mattresses with reduced sensitivity to open flames. This target will provide a mattress and bed that will resist burning when exposed to an open flame and when the room or home begins to burn. ❹ To slow down the burning rate of mattresses, engineers and chemists have studied mattress and base structures to identify how open flames can affect these structures and identify techniques for retarding fire spread. These engineers and chemists have modeled the gaskets and shim of mattresses and bases as fuel sources, and have developed techniques for retarding the burning of such materials. To this end, the mattress is designed to contain two key fire protection systems. The first fire protection system is a fire barrier in the mattress that isolates the highly flammable material contained in the core cushion of the mattress. The second fire protection system is a chemical/polymer fire retardant additive that can be used to reduce the flammability of the jacket and other layers outside the fire barrier. These existing fire protection systems in mattresses have greatly reduced the burning time of the mattress and improved the survival of the mattress fire. However, studies of mattresses exposed to open flames for extended periods of time have shown that even mattresses treated with fire-resistant compounds will begin to burn over time, in many cases by slowing the combustion by adding a toothing compound that anodes the flame. 'But in some cases, it has been found that the bed or base of the burning bed sometimes ignites for at least a short period of time. Of course 6 200924672 I don't want to be like this. Therefore, there is still a need to improve the manufacture of mattresses and bases that are more resistant to open flames and combustion. However, there is still room for improvement.

The thickness of the side walls of the rigid body is generally substantially uniform and the thickness can be selected in relation to the desired fire resistance/flame resistance. Similarly, the amount of FR material that is mixed with or coated on the rigid body can vary depending on the fire resistance/flame resistance sought.
