  • Patent number: 6823884
    Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.

  • Patent number: 6745420
    Abstract: The invention modulates the air-volume in both mattress-type foam and traditional coil spring cores interactively, obtaining a wide variety of levels of density and indentation force deflection (IFD or spring-back force). Foam core modulation is used to soften or harden the upper surface of the combined two elements to form enhanced-comfort support surfaces. The combinations include multiple chambers of which at least one is filled with self-inflating foam. In most configurations of the present invention, the chambers are completely sealed and are not air communicable with each other. Each chamber is fitted with a valve used to selectively withdraw air from it—but never to pressurize it by adding air forcibly. The combinations of core layers include traditional coil spring cores that may or may not be completely enclosed in their own enclosure. When air is extracted from a self-inflating foam core, its surface softens uniformly, density increases while its IFD value drops.

  • Patent number: 6687937
    Abstract: A moisture drying mattress comprised of at least one cushion that has opposite top and bottom surfaces and a plurality of apertures that extend through the cushion from the bottom surface to the top surface. An air channel mat is positioned below the cushion. The air channel mat is adapted and dimensioned to fit beneath the cushion and support the cushion bottom surface in a spaced relation above a bottom base of the mat to thereby form an air flow space between the cushion and mat through which air can flow. A vapor permeable, liquid impermeable cover encases the air channel mat and the cushion defining a vapor evaporation area under the cover. The air channel mat defines a moisture drying zone within the vapor evaporation area. An air pump is provided for selectively supplying a flow of air to the air channel mat. A controller is provided to control the flow of air to the air channel mat to evaporate the vapor in the vapor evaporation area.

  • Patent number: 6684434
    Abstract: A mattress assembly for supporting a patient includes a body support portion having a head end, a foot end, and a knee support portion. The body support portion has a first air zone extending from the head end to the knee support portion and a second air zone extending from the knee support portion to the foot end. The mattress assembly also includes a control module configured to supply air to the first and second air zones to maintain the first air zone at a substantially constant first pressure and to maintain the second air zone at a substantially constant second pressure. The second pressure is less than the first pressure to provide reduced pressure on a patient's calves and feet located on the second air zone.

  • Patent number: 6684433
    Abstract: A pressure adjustable foam support apparatus includes a resilient, air pressure adjustable, self-inflating foam core. A flexible, airtight cover encloses the core. One or more air passageways are formed through the covering in pneumatic communication with the foam core. Each passageway carries a valve for alternately permitting and blocking passage into and out of the core through the passageway. The valve is opened to exhaust air from and at least partially collapse the core and to allow a core that is at least partially collapsed to draw in air through the passageway and expand. The valve is closed to maintain a selected air pressure within the core whereby corresponding levels of density and firmness (IFD) are exhibited by the core. At least one level of density and firmness provides the core with a viscoelastic or latex foam feel hence greatly reducing pressure points and increasing comfort.

  • Patent number: 6671911
    Abstract: Multiple foam-filled cells form a cushioned support surface of a seat or mattress. Individual cells may be collapsed by connection through a manifold and valve to a vacuum source. The collapsed cell essentially removes contact pressure in a localized area of the person supported on the surface and restores localized blood flow. After a pre-determined time interval, atmospheric pressure is readmitted to the cell.
