15. A portable sacral support device accordingly to claim 1 , wherein the inner arch and outer arch are conjoined to the pedestal, together define a horse-shoe-shaped slot.
16. A portable sacral support device accordingly to claim 1 , wherein the inner arch provides a cantilevered support for an main body, and wherein the inner arch defines a portal capable of aligning with the vented center relief portion of the main body.
17. A sacral support device comprising:
a main body comprising:
a center support portion;
relief arms disposed laterally to the center support portion;
an upper support portion connected to the center support portion and the relief arms; and
a support skirt connected to the center support portion and to the relief arms; and
a support frame attached to the main body, the support frame comprising;
an outer arch;
an inner arch medial to the outer arch; and
a base portion;
wherein the support frame is capable of attachment to a seat back frame assembly having a frame and springs or suspension.
18. A sacral support device accordingly to claim 17 , wherein each relief arm independently, with the center support portion, upper support portion, and support skirt, defines an elongated slot portion in the main body.
19. A sacral support device accordingly to claim 17 , wherein a surface of the main body includes ribs, said surface of the main body being proximate to the support frame.
20. A sacral support device accordingly to claim 17 , wherein the center support portion of the main body is attached to the inner arch of the support frame.
21. A sacral support device accordingly to claim 17 , wherein said attachment of the support frame comprises attachment to the frame of the seat back assembly.
22. A sacral support device accordingly to claim 17 , wherein said attachment of the support frame comprises attachment to the frame and springs, or to the suspension, of the seat back assembly.
23. A sacral support device accordingly to claim 22 , wherein said attachment of the support frame further comprises attachment of the support frame to the frame and springs, or to the suspension, of the seat back assembly.
24. A sacral support device accordingly to claim 17 , wherein each relief arm forms an arc rearwardly curving between its connections to the upper support portion and support skirt.
25. A sacral support device accordingly to claim 17 , wherein the main body and support frame comprise a thermoplastic.
26. A sacral support device accordingly to claim 25 , wherein the thermoplastic is viscoelastic.
27. A sacral support device accordingly to claim 26 , wherein the thermoplastic comprises a polyester elastomer.
28. A sacral support device accordingly to claim 27 , wherein the polyester elastomer has a flex modulus in the range of from about 1200 to about 2500 psi as measured by the ASTM D790 or ISO 178 method for flex modulus determination.
29. A sacral support device accordingly to claim 17 , wherein the inner arch and outer arch, conjoined to the base portion, define a horse-shoe-shaped slot.
30. A sacral support device accordingly to claim 17 , wherein the inner arch provides a cantilevered support for an main body, and wherein the inner arch defines a portal capable of aligning with the vented center relief portion of the main body.
