Ribbed gel devices for cushioning purposes.
1. A ribbed gel cushioning member comprising:
a first ribbed gel cushioning element having a plurality of first elongated element ribs extending continuously and longitudinally in a first direction in an undeformed condition, the first direction oriented parallel to a major plane of the ribbed gel cushioning member, at least some of the first element ribs being capable of deforming under a load; and
a second ribbed gel cushioning element disposed adjacent to the first ribbed gel cushioning element and having a plurality of second elongated element ribs extending continuously and longitudinally in a second direction in an undeformed condition, the second direction oriented parallel to a major plane of the ribbed gel cushioning member, the second direction oriented at an angle relative to the first direction other than parallel, at least some of the second element ribs being capable of deforming under a load, at least some of the first element ribs and at least some of the second element ribs comprising an elastomeric gel;
wherein the first ribbed gel cushioning element and the second ribbed gel cushioning element are integrally formed with one another such that the first ribbed gel cushioning element and the second ribbed gel cushioning element comprise regions of a single unitary body, each elongated element rib of the plurality of first elongated element ribs integrally adjoining at least one elongated element rib of the plurality of second elongated element ribs over a generally planar area in a plane of intersection between the first ribbed gel cushioning element and the second ribbed gel cushioning element, the generally planar area defined by a width of each of the integrally adjoining elongated element ribs of the plurality of first elongated element ribs and the at least one elongated element rib of the plurality of second elongated element ribs.
2. The ribbed gel cushioning member of claim 1 , wherein the first elongated element ribs are configured to buckle at a first load, and the second elongated element ribs are configured to buckle at a second load differing from the first load.
3. The ribbed gel cushioning member of claim 1 , wherein the first elongated element ribs comprise a first gel having a first hardness, and the second elongated element ribs comprise a second gel having a second hardness differing from the first hardness.
4. The ribbed gel cushioning member of claim 1 , further comprising fabric disposed between the first ribbed gel cushioning element and the second ribbed gel cushioning element, the fabric connected to each of the first ribbed gel cushioning element and the second ribbed gel cushioning element.
5. The ribbed gel cushioning member of claim 1 , wherein the first ribbed gel cushioning element and the second ribbed gel cushioning element differ in at least one of length, width, and height.
6. The ribbed gel cushioning member of claim 1 , wherein at least one elongated element rib of the first elongated element ribs has a thickness differing from a thickness of at least one elongated element rib of the second elongated element ribs.
7. The ribbed gel cushioning member of claim 1 , wherein the first elongated element ribs and the second elongated element ribs are configured to buckle at a load, and wherein the first elongated element ribs and the second elongated element ribs are configured such that buckling of an elongated element rib of the first elongated element ribs and the second elongated element ribs causes a reduction in load carrying ability of the elongated element rib of the first elongated element ribs and the second elongated element ribs.
8. The ribbed gel cushioning member of claim 1 , wherein each of a gel of the first ribbed gel cushioning element and a gel of the second ribbed gel cushioning element comprises a solid elastomer extended by at least 20 parts of a plasticizer per 100 parts of the solid elastomer by weight.
9. The ribbed cushioning member of claim 8 , wherein the solid elastomer of each of the gel of the first ribbed gel cushioning element and the gel of the second ribbed gel cushioning element is independently selected from SEEPS polymers, SEBS polymers, and SEPS polymers.
10. The ribbed gel cushioning member of claim 9 , wherein the second direction is oriented at an angle of about 90° relative to the first direction.
11. The ribbed gel cushioning member of claim 10 , wherein the first elongated element ribs comprise a first gel having a first hardness, and the second elongated element ribs comprise a second gel having a second hardness differing from the first hardness.
12. The ribbed gel cushioning member of claim 11 , wherein the first elongated element ribs extend at least substantially parallel to one another from one side of the first ribbed gel cushioning element to another side of the first ribbed gel cushioning element.
13. The ribbed gel cushioning member of claim 1 , wherein the first elongated element ribs extend at least substantially parallel to one another from one side of the first ribbed gel cushioning element to another side of the first ribbed gel cushioning element.
14. The ribbed gel cushioning member of claim 13 , wherein each of a gel of the first ribbed gel cushioning element and a gel of the second ribbed gel cushioning element comprises a solid elastomer extended by at least 20 parts of a plasticizer per 100 parts of the solid elastomer by weight.
15. The ribbed cushioning member of claim 14 , wherein the solid elastomer of each of the gel of the first ribbed gel cushioning element and the gel of the second ribbed gel cushioning element is independently selected from SEEPS polymers, SEBS polymers, and SEPS polymers.
16. The ribbed gel cushioning member of claim 15 , wherein the first elongated element ribs comprise a first gel having a first hardness, and the second elongated element ribs comprise a second gel having a second hardness differing from the first hardness.
17. The ribbed cushioning member of claim 16 , wherein the first elongated element ribs and the second elongated element ribs are oriented at about 90° relative to one another.
18. The ribbed gel cushioning member of claim 13 , wherein the first elongated element ribs comprise a first gel having a first hardness, and the second elongated element ribs comprise a second gel having a second hardness differing from the first hardness.
