Support or padding including expandable cells whose cell body in its resting state seen in transverse section is individually delimited by at least two concentric perimeters, the walls of the cell in its resting state rejoining each of the perimeters are characterized by the fact that the portion of the wall of the cell rejoining two points located each on one of the concentric perimeters 6 and 7 can be strictly in a straight line during its centripetal path, if between two others points 28 at the entrance of the successive fissures, slits or clefts 4 located on the external perimeter 7 the path followed takes at least for a certain length an aspect strictly of a straight line or flat part 29, one of the last two points 28 being the same as the first one located on the external perimeter 7 at the junction or exit of a fissure: all of the consecutive points of this flat part 29 being further away or distal in relation to the center 24 of the cell than the other points, outside of the flat part 29, constitutive of the sheath 7 on its path between two points 28 located at the junction of the successive fissures 4.
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.
Support padding comprising a plurality of expandable cells, wherein each individual cell, in transverse section, is delimited by at least two concentric perimeters, an inner and an outer perimeter, which are generally coaxial with a center of a cell, the outer perimeter defining a sheath, each cell having walls which extend between the inner and the outer perimeters, said walls extending in essentially a jagged line at least a portion of a distance from the inner perimeter outward toward the outer perimeter, walls diverging from each other at least over the same distance, with opposed cell walls defining a slit therebetween, and further including cells characterized by the fact that a cell, in its resting state, in transverse section of the walls, an external sheath having four slits with opposed essentially parallel walls defining a slit.
Support padding including a plurality of expandable cells, at least a first one of the plurality of expandable cells having a wall forming first and second branches in a transverse section of the first cell in a resting state, the first and second branches separated by first and second slits, the first branch comprising first and second walls of the first and second slits, respectively, the first and second walls being divergent away from a center of the cell such that at least a third wall joins the first and second walls, the third wall being along an outer perimeter of the wall of the cell.
Support padding comprising an expandable cell whose section in transverse in a resting state has wings, each of the wings being perceptibly triangular with an apex closest to a center of the cell, at least two sides of each of the wings being non-parallel for the totality of each of the wings and corresponding to two successive fissures, wherein each of the fissures being defined between successive wings, a third side of each of the wings including at least one flat part along an external sheath, the flat part being further spaced from the center than other portions of the third side.
