Abstract
A cushion includes interconnected walls that define an array of buckling columns. Each buckling column of the array of buckling columns includes a plurality of buckling points at different elevations along a height of the buckling column. The buckling points buckle under different loads. Methods of designing cushions with a plurality of buckling points are also disclosed.
Claims26
A cushion, comprising:
- a plurality of interconnected walls defining an array of buckling columns, each wall of the plurality of interconnected walls having a height and including a base buckling point extending laterally across the wall at a lower elevation along the height of the wall and a top buckling point extending laterally across the wall at a higher elevation along the height of the wall to enable each buckling column of the array of buckling columns to buckle at at least two elevations.
A cushion, comprising:
- a plurality of interconnected walls defining an array of buckling columns, each wall of the plurality of interconnected walls having a height and including a base with a base thickness at a lower portion of the height of the wall and a top with a top thickness at a higher portion of the height of the wall, each buckling column including an interior surface defining a void extending along a height of the buckling column.
A method for designing a cushion, comprising:
- determining a thickness of the cushion and a height of interconnected walls and buckling columns of the cushion;
- determining a number of buckling points to be provided along the height of each buckling column of the buckling columns of the cushion;
- and
- determining a threshold load required to cause each buckling point of the plurality of buckling points to buckle.
