Abstract

The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable.

Claims

1-33. -33. (canceled)

34. A gelastic cushion comprising

A. a first set of buckling walls

(i) made of a first gelastic material having a first triblock polymer of the general configuration A-B-A and a first plasticizer;

(ii) 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,

(iii) 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,

(iv) 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;

B. a second buckling wall

(i) made of a second gelastic material having a second triblock polymer of the general configuration A-B-A and a second plasticizer;

(ii) positioned within the first opening area,

(iii) interconnects to

(a) a first wall of the first set of buckling walls at 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 wall of the first set of buckling walls at a second interconnection area that extends from the first set of buckling walls'"'"' bottom surface a distance greater than zero along the second wall toward the first set of buckling walls'"'"' top surface wherein the first interconnection area is diametrical to the second interconnection area;

(iv) 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 the second height of the second buckling wall is a first differential distance; and

(v) has a second width that allows the second buckling 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.

35. The gelastic cushion of claim 34 wherein the first width and the second width are the same width.

36. The gelastic cushion of claim 34 wherein the first width and the second width are different widths.

37. The gelastic cushion of claim 34 wherein the second wall has a top surface having a concave shape between the first interconnection area and the second interconnection area.

38. The gelastic cushion of claim 34 wherein the second wall has a top surface having a convex shape between the first interconnection area and the second interconnection area.

39. The gelastic cushion of claim 34 wherein the second buckling wall has a top surface having a planar shape between the first interconnection area and the second interconnection area.

40. The gelastic cushion of claim 34 further comprising a third buckling wall

(i) made of a third gelastic material having a third triblock polymer of the general configuration A-B-A and a third plasticizer;

(ii) positioned within the first opening area,

(iii) interconnects to

(a) a third wall of the first set of buckling walls at a third interconnection area that extends from the first set of buckling walls'"'"' bottom surface a distance greater than zero along the third wall toward the first set of buckling walls'"'"' top surface and

(b) a fourth wall of the first set of buckling walls at a fourth interconnection area that extends from the first set of buckling walls'"'"' bottom surface a distance greater than zero along the fourth wall toward the first set of buckling walls'"'"' top surface wherein the third interconnection area is diametrical to the fourth interconnection area and is not the first interconnection area or the second interconnection area;

(iv) has a third height, which is lower than the first height and the second height wherein the difference between the first height and the third height is a second differential distance D3 and the difference between the second height and the third height is a third differential distance;

(v) a third width that allows the third buckling wall to buckle into the first opening area if the force applied to

(a) the first set of buckling walls buckles the first set of buckling walls a distance greater than the second differential distance and

(b) the second buckling wall buckles the second buckling wall a distance greater than the third differential distance.

41. The gelastic cushion of claim 40 wherein the first width, the second width, and the third width are the same width, different widths or combinations thereof.

42. The gelastic cushion of claim 40 wherein the second buckling wall has a top surface having a shape selected from the group consisting of convex, concave, planar, and combinations thereof;

and the third buckling wall has a top surface having a shape selected from the group consisting of convex, concave, planar, and combinations thereof.

43. The gelastic cushion of claim 34 wherein the gelastic structure is incorporated into a portion of a mattress design.

44. The gelastic cushion of claim 34 wherein the first gelastic material and the second gelastic material can be the same or different materials.

45. The gelastic cushion of claim 40 wherein the first gelastic material, the second gelastic material, and the third gelastic material can be the same materials, different materials or combinations thereof.

46. The gelastic cushion of claim 34 wherein the second buckling wall has a protrusion and the protrusion interconnects to the first wall of the first set of buckling walls at the first interconnection area.

47. The gelastic cushion of claim 34 wherein the second buckling wall and the first set of buckling walls are formed in the same mold with the same gelastic material so the second buckling wall interconnects to the first wall of the first set of buckling walls at the first interconnection area.

48. The gelastic cushion of claim 40 wherein the second buckling wall has a gap to receive a portion of the third buckling wall.

49. The gelastic cushion of claim 48 wherein the third interconnection area receives a portion of the third buckling wall.

50. The gelastic cushion of claim 34 further comprising a peg positioned below the second buckling wall.

51. The gelastic cushion of claim 34 further comprising a peg positioned below the gelastic cushion and attached to a non-woven.
