  • Patent number: 5749111
    Abstract: A cushion that includes a cushioning element. The cushioning element has a number of substantially parallel elongate columns formed in a gelatinous cushioning media. The columns are configured so that when a force is applied to the cushioning element in a direction that is generally parallel to the longitudinal axes of the columns, the cushioning element will yield by a combination of compressability of the cushioning media and bucklability of the walls of the columns. In particular, the walls of columns which are located beneath a protruberance on an object being cushioned tend to buckle, permitting the cushioning element to conform to the shape of the cushioned object while evenly distributing a supporting force across the contact area of the cushioned object and avoiding pressure peaks. The preferred cushioning media is a gelatinous elastomer or gelatinous viscoelastomer. Various configurations of cushioning elements, including sidewall supports, are disclosed.

  • Patent number: 5652985
    Abstract: A pressure relief support system utilizes a self-adjusting approach to maintaining generally constant pressure in fluid support bladders. A constant force, such as from a constant force linear spring or from a counterweight system, is applied directly to a fluid support bladder or to a reservoir in fluid communication with such bladder. Plural self-adjusting arrangements may be provided in a single device for fabricating a support body with sectionalized support. Such arrangements may be incorporated into mattress support systems or into seating arrangements or other alternative uses. By appropriately selecting system components, such as the amount of the constant force applied, the original volume of fluid to which the force is applied, and the reservoir size, pressure dispersion for a patient or supported object of any type may be controlled at a predetermined generally constant point.

  • Patent number: 5626657
    Abstract: A composite mixture of spherical objects and lubricant useful for its cushioning properties is disclosed and claimed. The composite mixture may be composed of microspheres typically less than 2000 microns in diameter with inert atmospheres sealed within their interiors and any of a variety of lubricants facilitating sliding and rolling movement between microspheres. Typically the composite mixture includes lubricant in a quantity sufficient to substantially coat the exterior surface of essentially all of the spherical objects, but in a quantity less than would cause dispersion of the spherical objects in the lubricant sufficient to physically separate the spherical objects from each other and substantially reduce the sliding and rolling contact of the spherical objects with each other. The preferred lubricant is a visco-elastic fluid that has a principle molecule and a cross-linking agent.
