20090025150 | Systems and methods for hinged bedding assemblies - In many aspects, the systems and methods described herein include mattress having a top sleeping layer disposed on top of a support layer. The support layer includes polyurethane foam having channels comprising one or more slits on both sides of a surface to act as hinges for articulation. The channels may be aligned with the joints of the articulated sections of the foundation or frame of the adjustable bedding assembly. When the sections articulate about the joints, the channels allow the overlying top layer to conform to the sections while reducing wear and tear therein. | 01-29-2009 |
20090133195 | MATTRESS - A description is given of a mattress with at least one elastic basic body. The basic body has at least one channel in which at least one resilient rake can be arranged. The resilient rake includes an elongate, elastic crosspiece which is capable of torsion. A multiplicity of resilient arms are fastened on the crosspiece, each being arranged essentially transversely to the crosspiece. | 05-28-2009 |
20090183315 | INNERSPRING DAMPENING INSERTS - Dampened and zoned innersprings for use in support systems such as mattresses and furniture have dampening inserts in the form of foam pieces which fit integrally with the springs or coils of an innerspring. Dampened innersprings with one or more foam dampeners inserted between springs or coils of an innerspring, and more particularly foam dampener inserts which are configured to extend between multiple adjacent or aligned springs or coils, and which also have segments which fit between individual turns or convolutions of each spring or coil with which the insert is engaged Mechanical engagement of the innerspring by the foam dampening inserts insures alignment and registration of the innerspring and foam components, and compression and recoil of the individual coils of the innerspring occurs in conjunction with compression and decompression of the foam dampening inserts. | 07-23-2009 |
20110107523 | MATTRESS INNERSRPING INSERTS AND SUPPORTS - Innerspring dampening foam inserts are disclosed in various combinations with mattress innersprings having a plurality of helical form coils interconnected in an array in which the coils are generally aligned in rows and columns, each of the coils having a generally cylindrical coil body formed by helical turns of wire with openings between each of the helical turns of wire, and first and second ends to the coil body also formed by the wire, each of the coil bodies being spaced apart in the array. At least one innerspring insert is inserted into an innerspring in spaces or channels between the spaced apart coils. The innerspring dampening inserts, which are preferably made of foam, may have a generally H-shaped configuration with upper and lower parallel lateral members and a transverse member that extends between and bisects the upper and lower lateral members. In another embodiment, the innerspring inserts may be generally T-shaped having a lower lateral member, a vertical member which is perpendicular to and bisects the lower lateral member and a lateral extension which extends outward from one side of the vertical member. The innerspring inserts may create or define zones or regions of the innerspring which have different support characteristics from other zones or regions by dampening or altering the spring rates and support characteristics of the innerspring in the areas or regions where the insert are located. The innerspring inserts may also be placed at or near the border or edges of the innerspring to provide increased stability in the perimeter or edge areas of the support surface of a mattress. | 05-12-2011 |
20120066838 | SYSTEMS AND METHODS FOR HINGED BEDDING ASSEMBLIES - In many aspects, the systems and methods described herein include mattress having a top sleeping layer disposed on top of a support layer. The support layer includes polyurethane foam having channels aligned with the joints of the articulated sections of the foundation or frame of the adjustable bedding assembly. When the sections articulate about the joints, the channels allow the overlying top layer to conform to the sections while reducing wear and tear therein. | 03-22-2012 |
20130081207 | Coated Springs and Mattress Made Thereof - The invention describes a coated spring for mattresses that comprises a helical compression spring and a wrapping in the form of a bag containing the spring, wherein the bag containing the spring is injected with a polymeric reaction mixture, which after reacting or curing produces a polymeric foam, preferably of flexible polyurethane up to a desired volume in order to cause the spring to change its flexion or compression properties, as well as the method for its manufacturing and its use in the manufacturing of mattresses of different kinds. | 04-04-2013 |
20130269115 | INNERSPRING MATTRESS WITH SHREDDED FOAM FILL - Disclosed is an innerspring bed mattress with shredded fill inside the mattress central spring core, around, between, in and inside the springs. The shredded fill is generally particulate, and may be of conventional types, sizes and shapes of resilient and compressive materials. Preferably, the fill is shredded organic latex rubber foam fill, obtained from the scrap of organic latex rubber mats used in conventional mattress upholstery layers manufacture. Alternatively, the fill may be specially designed and manufactured to obtain specific dampening characteristics for a specific combination of spring, upholstery and fill types, for example. | 10-17-2013 |
20140373280 | Pocketed Spring Assembly Comprising Strings of Springs Having Y-Shaped Seams and Inserts - A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The product may have individual inserts between adjacent strings of springs. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart. | 12-25-2014 |
20140373281 | Pocketed Spring Assembly Comprising Strings of Springs Having Y-Shaped Seams and Inserts - A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The product may have individual inserts between adjacent strings of springs. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart. | 12-25-2014 |
20150335163 | MATTRESS ASSEMBLY - A mattress assembly includes a first layer of viscoelastic foam defining an upper surface, and a second layer of non-viscoelasiic foam supporting the first layer. The mattress assembly also includes a plurality of static spring elements positioned beneath the upper surface for enhancing a firmness of the combined first and second layers. | 11-26-2015 |
20150342362 | POCKET COIL SPRING ASSEMBLY INCLUDING FLEXIBLE FOAM - A pocket coil spring assembly is provided that includes a coil spring having an upper portion and a lower portion collectively defining an interior cavity of the coil spring. The pocket coil spring assembly further includes a fabric pocket encasing the coil spring with a top area covering the upper portion of the coil spring and a bottom area covering the lower portion of the coil spring. An amount of flexible foam is positioned in the interior cavity of the coil spring such that a top surface of the flexible foam extends above the coil spring. A mattress assembly is further provided that includes a plurality of the pocket coil spring assemblies. | 12-03-2015 |
20160029809 | ENCASED ASYMMETRIC COIL INNERSPRINGS WITH ALTERNATING COIL SPRING ORIENTATIONS - Encased coil innersprings with alternating spring coil orientations utilize a common coil configuration and a uniform encasement or pocket configuration, and wherein the coils have an asymmetrical configuration and the vertical end-up orientation of the coils that is alternated or otherwise varied. Selected coils in different areas or patterns in the array of pocketed coils that form the spring core are inverted, relative to a support surface of the spring core, within the individual pockets. The inverted coils have spring characteristics including spring rate, stiffness and initial deflection force which are different from the spring characteristics of the non-inverted coils due to the asymmetry of the coils along a longitudinal axis. | 02-04-2016 |
