Abstract:
A support cushion cover assembly for removing humidity and heat from a contact surface of a support cushion is provided. The support cushion cover assembly comprises a support cushion cover that includes an upper panel having a top surface, a bottom surface, and a middle spacer layer positioned between the top surface and the bottom surface. The support cushion cover further includes an amount of hygroscopic material and at least one flexible tube that defines a plurality of fenestrations. Each fenestration is in fluid communication with the middle spacer layer of the upper panel. An air pump is further included in the cover assembly and is operably connected to the flexible tube, such that an amount of air is delivered into the flexible tube and the middle spacer layer of the cover. Methods for removing humidity from a contact surface of a support cushion are also provided.
Abstract:
A mattress assembly includes a first layer of viscoelastic foam defining an upper surface, and a second layer of non-viscoelastic foam supporting the first layer. The mattress assembly also includes a plurality of spring elements positioned beneath the upper surface for enhancing a firmness of the combined first and second layers. Each of the spring elements includes a first spring having a first spring rate and a second spring having a second spring rate different than the first spring rate.
Abstract:
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.
Abstract:
A support cushion is provided for moving an amount of air through the support cushion. The support cushion includes a body supporting layer having a removable portion, an upper base layer defining one or more air conduits In fluid communication with the removable portion, a lower base layer defining a cavity, and a bottom layer. A fan is positioned within the cavity such that the fan is in fluid communication with the one or more air conduits defined by the upper base layer. The fan is thus capable of drawing air from the top surface of the body supporting layer, through the removable portion, through the one or more air conduits in the upper base layer, and exhausting the air into the bottom layer. Methods of actively ventilating a support cushion are also provided.
Abstract:
A support cushion for providing prolonged cooling at an upper surface of the support cushion is provided. The support cushion includes a body supporting portion having an upper surface, at least one region of phase change material positioned and configured to provide cooling at the upper surface of the body supporting portion, and a copper layer underlying and operably connected to each region of phase change material.
Abstract:
Retainer bar assemblies are provided for use is an adjustable base of a support cushion. The retainer bar assemblies include a retainer bar having a horizontal rod and two legs connected to the horizontal rod with an end portion that extends from each leg in a direction substantially parallel to the horizontal rod. The retainer bar assemblies further include a pair of brackets where each bracket defines at least one channel for receiving the end portion of the two legs. Each channel has a vertical segment and an angled segment such that each channel is configured to allow the horizontal rod to be moved upward and rotated away from each bracket. Adjustable support cushions or bed assemblies that include the retainer bar assemblies are also provided.
Abstract:
A support cushion for providing individualized heating and cooling to a user resting on the support cushion is provided. The support cushion includes a body supporting layer, a plurality of thermoelectric elements positioned and configured to selectively provide heating or cooling of the body supporting layer, a heat transfer layer positioned adjacent to the body supporting portion and operably connected to the thermoelectric elements, a base layer positioned adjacent to the heat transfer layer opposite the body supporting layer and defining one or more inlet and outlet conduits, and one or more fans operably connected to each of the outlet conduits. Methods of controlling the surface temperature of a support cushion are also provided.
Abstract:
A mattress includes a first layer of viscoelastic foam having an upper surface and a layer of non-viscoelastic foam supporting the first layer. The mattress also includes a plurality of static bolster elements positioned beneath the upper surface and clustered together to define a plurality of troughs between adjacent bolster elements. The first layer of viscoelastic foam is further compressible in regions of the mattress corresponding with the troughs than surrounding regions corresponding with the bolster elements. Each of the bolster elements is capable of exerting a reaction force having a lateral component on an individual pushing against the bolster element with a line of action through one of the troughs.
Abstract:
A massage cushion assembly for providing a massage to a user resting on the massage cushion assembly is provided. The massage cushion assembly includes a body supporting portion having a first surface and a second surface opposite the first surface, a base portion defining one or more slots extending longitudinally through the base portion, and a massage unit including one or more massage members. Each of the massage members is movable along a length of a particular slot and between a raised position and a lowered position. Each massage member is further positioned in a particular slot such that a head portion of the massage member extends out of the slot and presses against the second surface of the body supporting portion when the massage member is in the raised position.
Abstract:
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.
