Patent ID: 7823233

Claim:
A method to produce a gelastic cushion comprising: A. selecting a mold material; B. cutting the mold material to create a gelastic structure having (1) a first set of buckling walls (i) define a first bottom open-ended opening area wherein there is no gelastic skin material positioned on or across the entire first set of buckling walls' bottom surface, (ii) are the tallest walls in the gelastic cushion with a first height ranging from the first set of buckling walls' bottom surface to the first set of buckling walls' top surface, (iii) have a first width that allows the first set of buckling walls to buckle, when a force is applied at the first set of buckling walls' top surface to the first set of buckling walls, into the first opening area or into (a) an adjacent second opening and/or (b) exterior to the perimeter of the gelastic cushion; (2) a second wall (i) positioned within the first opening area, (ii) interconnects to (a) a first interconnection area that extends from the first set of buckling walls' bottom surface a distance greater than zero along the first wall toward the first set of buckling walls' top surface and (b) a second interconnection area that extends from the first set of buckling walls' bottom surface a distance greater than zero along the first wall toward the first set of buckling walls' top surface wherein the first interconnection area is diametrical to the second interconnection area; (iii) has a second height, which is less than the first height of the first set of buckling walls and the difference between the first height of the first set of buckling walls and second height of the second wall is a first differential distance; (iv) has a second width that allows the second wall to buckle into the first opening area if the force applied to the first set of buckling walls buckles the first set of buckling walls a distance greater than the first differential distance; C. pouring a gelastic material into the mold to form the gelastic cushion.
