Abstract (en)
[origin: WO9858571A1] The invention concerns a support or upholstery comprising expansible cells whereof the inoperative cell body in transverse cross-section is individually delimited by at least two concentric perimeters, the inoperative cell walls joining each of the perimeters are characterised in that the cell wall portion joining two points each located on one of the concentric perimeters (6 and 7) can be strictly in a straight line on its centripetal travel, if between two other points (28) at the opening of the successive chinks, slots or breaks (4) located on the outer perimeter the path followed takes on at least over a certain length the aspect of a strictly straight line or flat surface (29); one of the two last points (28) being the same as the first located on the outer perimeter (7) at the junction or exit of a chink; all the points constituting this flat surface (29) being more distant or distal relative to the cell centre (24) than the other points, outside the flat surface (29), constituting the cover (7) on its travel between two points (28) located at the successive chink (4) junction.
