    Abstract: A modular supporting element has a supporting surface for a user and includes a plurality of elastic modules, suitable for being deformed according to a direction substantially perpendicular to the supporting surface of the user. Each module has a side surface and an upper portion, wherein the modules are arranged juxtaposed to each other with the side surfaces substantially in contact or with the side surfaces at such a distance as not to prevent contact between one module and another during the elastic deformation movement. The modules have anti-friction surfaces arranged in a part of the side surface of the modules in such a way as to prevent interferences by friction between one module and another. The modular supporting element is made up of a plurality of modules with different rigidity from area to area without any appreciable influence between one module and another.

  • Patent number: 8065767
    Abstract: The present invention provides a safety apparatus as an aid for the prevention of Sudden Infant Death Syndrome: A mattress, fitting the dimensions of a standard-sized crib, is composed of three different layers, allowing a free flow of air through it to the infant lying in any position. The lowest layer has transverse channels allowing cross-wise air movement. The middle and top layers have vertical perforations through them allowing a vertical flow of air. Being composed of 3 layers, differing in density and firmness, the mattress is both firm and pleasant to the touch. Therefore, in addition to its primary function, the mattress provides a method to counter a potential delay in the motor development of the infant, which can result from prolonged lying in the supine position. A mesh sheet is stretched taut over the mattress and fastened securely to the vertical bars of the crib.

  • Patent number: 6598251
    Abstract: A body support system is provided having improved static and dynamic mechanical response characteristics and improved thermal regulation. The body support system can be of a modular construction to provide mechanical response characteristics suited to a particular user or group of users, or to a particular environment or use. In one embodiment, the body support system is a seat cushion comprising a foam layer with a central region, a plurality of spaced apart vertical foam columns that define a fluid reservoir in the central region, a plurality of fluid channels in the foam layer for communicating fluid in and out of the fluid reservoir, and an elastomeric layer having resilience and flow properties, such as a viscoelastic gel, positioned above the fluid reservoir.

  • Patent number: 6402775
    Abstract: Cooling pads, mattresses, and limb-comforming sleeves reduce a person's temperature by evaporative and/or conducting cooling. An open cell foam pad defines an internal air flow passages proceeding according to serpentine or other desired routing. The pad is wetted, and a blower circulates air through the air flow passage and evaporatively cools the pad by removing warm water vapor. By contacting the cooled structure, the person is conductively cooled. The pad also employs evaporative cooling if water is permitted to seep from the foam pad onto the person's skin and subsequently evaporate. Another cooling device is a multi-layer evaporative cooling mattress. The mattress comprises an open cell foam structure having a person-receiving side and a base side. At the person-receiving side lies an absorbent layer with internal liquid delivery lines, and optionally having an outer film applied thereto.

  • Patent number: 6272707
    Abstract: A support pad includes a low density layer of an air and water permeable three-dimensional matrix composed of a mat of polymeric material. The layer preferably has a smooth and planar contour on the top face, and a “peak and valley” contour on the bottom face. A pad may be maintained over the top face of the low density layer. Sheeting may be placed over at least the top face of the low density layer and the pad to provide a more comfortable surface for an individual to rest upon.

  • Patent number: 6182315
    Abstract: A 3-layer venting mattress structure comprised of a steel fiber layer sandwiched by net layers sewn on its periphery. Both upper and lower net layers are made of fiber or non-woven with interlaced mesh for venting purposes. The steel layer between the fiber layers is made of high-strength steel yarn lop-sided woven in a spiral and continuous fashion to provide a mattress that allows excellent air permeability and tensile strength with sufficient capability to withstand local area loads. Therefore, the present invention solves the poor ventilation problem of the prior art, achieves the evenly distributed load susceptibility of the mattress, and provides an innovative type of space arrangement.

  • Patent number: 6171333
    Abstract: A heating and cooling comforter for heating or cooling a user. The heating and cooling comforter includes an inner bladder comprising a pair of panels coupled together along the outer perimeter of the inner bladder to define an air space therebetween. Each of the panels of the inner bladder has a plurality of spaced apart air apertures therethrough into the air space of the inner bladder. A comforter cover is also included comprising a pair of panels coupled together along the outer perimeter of the comforter cover. The comforter cover has an elongate slit therein between the panels of the comforter cover. The inner bladder is inserted into the comforter cover. A vent cover is included having an arcuate upper wall and an open bottom. An elongate conduit is extended between the from the inner bladder and the vent cover to fluidly connect the air space of the inner bladder to the vent cover.
