发明名称 INDEPENDENT FOAM CELL SURFACE AND METHOD OF MAKING SAME
摘要 <p>An apparatus for reducing the occurrence of motion transfer across a bed when the apparatus is placed upon an independent coil construction mattress. The apparatus includes a substantially resilient pad having a size and shape substantially conforming to the size and shape of the mattress. The pad has a generally planar bottom surface sized and configured to lay upon the mattress further has an opposing load-bearing surface which defines a plurality of peaks extending therefrom. The load-bearing surface further defining a plurality of valleys extending between the load-bearing surface and the bottom surface. The peaks and valleys are arranged across the pad in a pattern to form a plurality of cells which depress independently of each other when pressure is exerted thereupon. A method of making the pad includes sandwiching a foam blank in-between two sacrificial sheets which are fed through two cylindrical rollers having protrusions formed thereon.</p>
