초록 ▼

A method of making a polyurethane foam mattress overlay so that it has several sections defined in a relatively flat support surface thereof. The sections are longitudinally disposed so as to correspond with different parts of a user\s body. Each such section has predetermined support characteristics which are selected in relationship with such characteristics for the other sections so as to define systematized support. Specific numerical ranges and inter-relationships for such sections are preferred. A plurality of projections are formed in each surface section. In general, the cross-sectional area of such projections at the overlay support surface or at a given depth therefrom is the same within each section, but differs from one section to another. Separation distances between such projections may also vary with the respective sections. The resulting tailored support characteristics in respective sections provide engineered support for all parts of a user\s body. Side edges of the projections may be bevelled and/or include a radius of curvature to enhance independent action of the projections. Channels for dissipating heat and moisture may be provided, and have characteristics which vary with the different support sections. An effectiveness index takes into consideration the thickness, indentation load deflection (i.e., stiffness), and density of a given pad, to assist practioners in selecting appropriate embodiments of the invention.

대표청구항 ▼

A method of making a mattress pad for providing systematized pressure dispersion for a person reclined thereon, comprising: providing a main body of resilient material having a predetermined thickness and predetermined density; and an upper support surface, defined by said main body, for receipt of a person thereon; making a plurality of parallel longitudinal and parallel transverse cuts in said main body to a given depth thereof, for defining a plurality of rectangular-shaped elements; defining a plurality of sections in said body, with each respective section including at least two adjacent transverse rows of said rectangular-shaped elements, and having predetermined element cross-sections which are generally constant over the respective section but which differ among said sections; wherein said cuts are made so as to form 25% ILD characteristics in respective sections in said body generally in a range from about 17 pounds to about 26 pounds, where 25% ILD stands for 25% indentation load deflection as defined by the number of pounds of pressure required to push a 50 square inch circular plate into said main body so as to compress same by 25% of its predetermined thickness, so as to form a support system for dispersing pressure in a desired manner for all parts of a person reclined thereon for optimized prevention of decubitus ulcers. *** BRS DOCUMENT BOUNDARY ***
