  • Publication number: 20110232002
    Abstract: A TPU composition comprising two or more TPU polymers is disclosed. The TPU composition gives a broad process window for melt coating applications. The blend of TPUs give better processing than either of the individual TPU polymers used in the blend alone. This results in melt coating which gives less matt and glossy streaks and allows faster coating speeds along with lower coating weight. The two or more TPU polymers used in the blend have a different soft segment. The different soft segment is created by using different molecular weight polyol for the TPU polymers or by using chemically different polyols.

The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.

  • Publication number: 20100101026
    Abstract: An adaptable surface system including a plurality of individually adjustable surface units and a plurality of pressure sensors. Each pressure sensor corresponds to one of the adjustable subsurface units and is positioned to measure an amount of pressure exerted upon the subsurface unit. The system also includes a controller that receives a first pressure value from a pressure sensor, compares the value to a threshold, and adjusts the height of the first subsurface unit based on the comparison. The controller also receives a second pressure value from a second pressure sensor, compares the second pressure value to the threshold, and adjusts the height of a second subsurface unit based on the comparison.

  • Patent number: 7681264
    Abstract: A cushion comprising an array of individual suspension elements arranged in a pattern wherein one embodiment the longitudinal axis of each suspension element in the array is positioned at a right angle or parallel to the longitudinal axes of the adjacent suspension elements. Each suspension element has a displaceable load-bearing surface, a first end wall, a second end wall, and an optional bottom wall, with load-bearing surface and recited walls defining an inner chamber. The material thickness of the load-bearing surface generally is greater than the material thickness of the end walls whereby the end walls deflect outwardly toward the load-bearing surfaces of adjacent support elements under load. The load-bearing surface can have a substantially arch-shaped, elliptical or rectangular cross-section and may be constructed from different materials to make a composite suspension element.

  • Patent number: 7644724
    Abstract: The invention relates to an assembly comprising an electromechanical device and a self-sealing valve, and in particular, to any inflatable device that includes the assembly. In one embodiment, the assembly comprises a valve housing defining an opening through which fluid can be provided to the inflatable device, a flexible diaphragm assembly that is configured to self-seal the opening with sufficient fluid pressure in the inflatable device and to open under sufficient fluid pressure from a fluid moving device, to provide fluid through the opening to and seal the inflatable device. The assembly further comprises an electromechanical device including an actuating arm, having a first position in which the actuating arm urges open the self-sealing valve and a second position in which the actuating arm does not act upon the self-sealing valve, so as to regulate an amount of fluid within the inflatable device. With this arrangement, a small, low power, low duty cycle electromechanical device can be used.

  • Patent number: 7636970
    Abstract: An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder. A middle layer below said top layer is partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, via a plurality of air vents in the middle layer, creating air-pockets arrayed on the top surface of the air mattress.

  • Publication number: 20090265857
    Abstract: The cushion according to the invention is made up of several layers of pneumatic elements (3) which each form a matrix (2). These pneumatic elements (3) each have a multiplicity of holes (5a) into which elastic spring elements, for example foam cylinders (1), are inserted. The pneumatic elements (3) are all substantially congruent, such that the holes (5a) of superposed pneumatic elements (3) are in each case located at the same places. An individual pneumatic element (3) is produced from two superposed sheets of an elastic plastic. The two sheets are welded sealingly to each other at the edges of the cushion and at the edges of the holes (5a). The holes (5a) are cut out after the welding. Each pneumatic element (3) has at least one connection for compressed gas. While supporting a patient, the pneumatic elements (3) are alternately supplied with compressed gas and then relaxed again.
