Abstract:
Support padding including a plurality of expandable cells, wherein each individual cell, in transverse section, is delimited by an inner and an outer perimeter, each generally coaxial with respect to a center of the cell with the outer perimeter defining a sheath, each cell having walls, which extend between the inner and the outer perimeters, being essentially linear from the inner perimeter outwardly for at least a portion of a distance to the outer perimeter, and wherein walls of a cell diverge from each other over at least such a linear portion, the walls also being arranged such that slits are defined between opposed walls of a cell extending inward from the external perimeter linearly a predetermined distance, and characterized by the fact that a cell, in its resting state in a transverse section of the walls, has an external sheath which is essentially square, and has four slits with opposed adjacent essentially parallel walls, with a flat part between two of the slits and having, at a minimum, as many flat parts as slits.
