Cellular cushions including support material and methods of fabricating same

摘要

A cellular cushion includes a base, a plurality of hollow cells, and support material. The base includes at least a first layer and a second layer. The plurality of hollow cells are coupled to, and extend outward from, only one of the first layer and the second layer. Each of the plurality of cells extends from a root defined at only one of the first layer and the second layer outwardly to an outer end. The plurality of cells are coupled together in flow communication via a plurality of channels extending between the cells. The support material is inserted within at least one of the hollow cells. The second layer coupled to the first layer such that the support material is between an inner surface of said at least one of the hollow cells and the second layer.

1. A cellular cushion comprising:
a base comprising at least a first layer and a second layer; a plurality of hollow cells coupled to, and extending outward from, only one of said first layer and said second layer, each of said plurality of cells extends from a root defined at only one of said first layer and said second layer outwardly to an outer end, said plurality of cells coupled together in flow communication via a plurality of channels extending between said cells; and support material inserted within at least one of said hollow cells, said second layer coupled to said first layer such that said support material is between an inner surface of said at least one of said hollow cells and said second layer, wherein a cross-sectional shape of said support material is different from a cross-sectional shape of said at least one hollow cell, such that a contour of a supporting surface of said at least one hollow cell changes from being defined by said cross-section of said at least one hollow cell to being defined by said cross-section of said support material as an immersion depth of a user is increased.
