Abstract
A cushioning element includes interconnected walls that define voids and hollow columns that are substantially cylindrical or cylindrical in shape. Some of the interconnected walls may project laterally from a wall that defines part of a hollow column to further define part of an interspace between a group of hollow columns. Methods of designing cushioning elements with hollow columns that are substantially cylindrical or cylindrical are also disclosed.
Claims7
A cushion comprising:
- an elastomeric cushioning material defining:
- a plurality of hollow columns that are cylindrical or substantially cylindrical;
- at least one lateral projection extending from an outer surface of each of the hollow columns, the at least one lateral projection joining a hollow column of the plurality of hollow columns with an adjacent hollow column of the plurality of hollow columns;
- and
- a plurality of interspaces defined between walls defining the hollow columns and at least partially defined by lateral projections of the hollow columns,
- wherein the plurality of hollow columns have a first buckling profile and the walls and the lateral projections that at least partially define the plurality of interspaces have a second buckling profile different than the first buckling profile, such that the plurality of hollow columns begin to buckle under a different applied force than the walls and the lateral projections that at least partially define the plurality of interspaces start to buckle.

A cushion comprising:
- an elastomeric cushioning material defining:
- a plurality of hollow columns that are cylindrical or substantially cylindrical positioned adjacent to each other, each hollow column having a first cross-sectional shape and/or size, taken perpendicular to a height of the hollow column;
- and
- a plurality of interspaces, each interspace defined by walls defining a group of hollow columns and having a second cross-sectional shape and/or size, taken perpendicular to a height of the interspace, that differs from the first cross-sectional shape and/or size,
- wherein the plurality of hollow columns have a first buckling profile based at least in part on the first cross-sectional shape and/or size, and the walls that define the plurality of interspaces have a second buckling profile based at least in part on the second cross-sectional shape and/or size, the second buckling profile being different than the first buckling profile.
