Multi-Sektions-Matratze und Auflage für eine systematisierte Verteilung des Druckes.

摘要

A polyurethane foam mattress pad or overlay (20) has a relatively flat support surface (30) and is divided into several longitudinally disposed sections (40, 50, 60) which correspond with different parts of a user's body; each section has predetermined support characteristics which are selected in relationship with such characteristics for the other sections so as to define systematized support of a patient. A plurality of projections (42, 52, 62) are formed in each surface section, and in general, the cross-sectional area of such projections at the support surface (30) or at a given depth therefrom is the same within each section, but differs from one section to another. The separation between contiguous projections may also vary from section to section to tailor the support characteristics in the respective sections (40, 50, 60) to provide engineered support for all parts of a user's body. Side edges (90, 92) of the projections (42, 52, 62) may be bevelled and/or rounded to enhance independent movement of the projections. Also, channels (44) for dissipating heat and moisture may be provided, and may have dimensional characteristics which vary from section to section.
