Title:
【発明の名称】発泡体マットレスコアを有するマットレス構造体
Document Type and Number:
Japanese Patent JP2000511086
Kind Code:
A
Abstract:
An elongated mattress core for a mattress structure includes a foam core having an upwardly-facing top surface, a bottom surface spaced apart from the top surface, and first and second elongated sides connecting the top and bottom surfaces. The foam core is formed to include a plurality of longitudinally spaced apart transverse slits extending downwardly from the top surface. Each slit terminates at a lower end spaced apart from the bottom surface by a first distance and extending transversely from a first slit end spaced apart from the first side of the foam core to a second slit end spaced apart from the second side of the foam core. Each adjacent pair of slits defines a foam column so that the foam core has a plurality of longitudinally spaced apart and transversely extending foam columns. Each foam column has a pair of generally vertical column side walls defining the slits. Each column side wall includes a shear coating having a low coefficient of friction so that each column can compress and decompress without drag forces resulting from frictional engagement with adjacent column side walls interfering with the compression and decompression.
