Bleach compatible polyolefin mattress cover
A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.
MATTRESS RETENTION ASSEMBLY AND RADIOFREQUENCY WELD IN SURFACE COVERS
A mattress assembly includes a mattress and an outer mattress shell that covers the mattress and has a patient support portion and a sleep deck portion. The outer mattress shell defines an interior surface and an exterior surface. A bonding strip is coupled to the interior surface of the outer mattress shell and a fastening strip is coupled to the exterior surface of the outer mattress shell. A weld extends through the exterior surface and through the interior surface of the outer mattress shell. A clasp locker is operably coupled to the fastening strip and detachably couples the patient support portion to the sleep deck portion of the outer mattress shell.
Self rising board molding
A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
Method and apparatus for creating a kneeler pad using a thermoforming process
The present invention is a system and method for manufacturing a framework for a padded cushion in the shape of a kneeler pad, wherein the framework is created using a thermoforming process to make rigid and plastic top and bottom shells that are then coupled together to form a framework to which upholstery is added to thereby form a padded kneeling cushion, wherein a fabric tightening system is also installed in the framework that enables the upholstery to be stretched tighter over the framework in order to tighten the upholstery around the cushion as the upholstery loses its shape and stretches over time, and wherein a system is provided to extend a length of the kneeler pads through the addition of expansion segments in the framework.
SUPERIMPOSED CUSHIONING ELEMENTS
A cushioning element includes a fabric, a first cushioning element on a first side of the fabric, and a second cushioning element on a second side of the fabric. The first cushioning element and second cushioning element may be superimposed. The fabric may include a first layer and a second layer that are superimposed, with the first cushioning element secured to and protruding from the first layer and the second cushioning element secured to and protruding from the second layer. Each of the first cushioning element and second cushioning element may include a plurality of interconnected walls formed from an elastomeric gel material. The walls of the first cushioning element and second cushioning element may be aligned or offset.
METHODS FOR FORMING CUSHIONING ELEMENTS ON FABRIC

The first cushioning element and second cushioning element may be superimposed. The fabric may include a first layer and a second layer that are superimposed, with the first cushioning element secured to and protruding from the first layer and the second cushioning element secured to and protruding from the second layer. Each of the first cushioning element and second cushioning element may include a plurality of interconnected walls formed from an elastomeric gel material. The walls of the first cushioning element and second cushioning element may be aligned or offset.

Method of manufacturing multi-hardness and multi-elasticity foam mattress by use of continuous foaming process and foam mattress manufactured thereby
A method of manufacturing a multi-hardness and multi-elasticity foam mattress in which a plurality of foam blocks are formed integrally with each other by use of a continuous foaming process the method comprising the steps of: arranging a plurality of nozzles above one end of a molding plate; installing a separation wall between two adjacent ones of the respective nozzles arranged at the molding plate; laminating a release paper on the top of the molding plate; spraying foaming solutions from the nozzles, respectively, wherein the release paper moves in a direction toward the other end of the molding plate corresponding to a moving speed of the foaming solution; and molding a foam body having a plurality of zones where a plurality of unit foam blocks have multi-hardnesses and multi-elasticities.
Composite cushions
A composite cushion includes a first cushioning element and a second cushioning element. The second cushioning element is formed in a manner that engages a peripheral engagement are of the first cushioning element to interlock the second cushioning element onto the first cushioning element. The second cushioning element may surround an outer periphery of the first cushioning element. In addition, a portion of the second cushioning element may be superimposed over a central cushioning area of the first cushioning element. Superimposed portions of the first and second cushioning elements may have an unsecured relationship (i.e., they are not directly secured to each other).
RESILIENT CORES WITH CONVECTION BARRIERS PARTICULARLY FOR INFLATABLE BODIES AND METHODS FOR MAKING THE SAME
Resilient cores preferably for inflatable bodies having resilient slabs that define a plurality of generally columnar holes or resilient arrays of generally columnar solids, methods for making such slabs and arrays, and articles incorporating the same wherein the cores further includes thermal transmission mitigation means for improving a core's resistance to heat transfer beyond the core's innate insulative properties. Non-exclusive and non-exhaustive examples of such thermal transmission mitigation means in slab core embodiments include consideration to hole or bore geometric cross section, frequency, pattern and orientation, the introduction of a thermal barrier at or within at least some holes or bores, and/or slab material selection/treatment.
