A cargo retainer system incorporates a load-bearing strap that extends over a cargo element, and a strap-retainer having an elastic portion that is stretched to a stretched length and attached to the load-bearing strap. The strap-retainer has clamp that attaches to the load-bearing strap and a hook on an opposing end to secure the strap retainer under tension, or with the elastic portion stretched. The strap-retainer provides an elastic retaining force on the load-bearing strap wherein the force exerted on the load bearing strap increase when the cargo shift away from strap-retainer and the force decreases when the cargo shifts toward the strap-retainer. A cargo retainer system may incorporate a strap-retainer on either side of the cargo element to provide complimentary and corrective elastic retaining forces on the load-bearing strap.

The strap-retainer of claim 1, wherein the elastic portion comprises rubber. 3. The strap-retainer of claim 1, wherein the elastic portion is configured to extend at least 100% of the original length and recover substantially back to said original length. 4. The strap-retainer of claim 1, wherein the first clamp portion has a substantially first planar body portion, and wherein the second clamp portion has a substantially second planar body portion that is configured to align substantially parallel with the first planar body portion when the clamp is in a closed configuration. 5. The strap-retainer of claim 4, wherein the aperture in the first clamp portion extends in a cross-length direction across the first planar body portion. 6. The strap-retainer of claim 1, wherein the clamp comprises a latch to hold the clamp in a closed configuration. 7. The strap-retainer of claim 1, wherein the clamp comprises a lock to retain the clamp in a closed configuration. 8. The strap-retainer of claim 1, wherein the protrusion has a height that is configured to extend completely through the aperture and past an outside surface of the first clamp portion when the clamp is in a closed configuration. 9. A cargo retainer system comprising: a. a load-bearing strap assembly comprising: i. a load-bearing strap extending from a hook-end comprising an extended-end hook to a ratchet apparatus;ii. a ratchet-strap extending from the ratchet apparatus to a ratchet-end hook;wherein the ratchet apparatus is configured to pull and retain the load-bearing strap from the hook-end to the ratchet apparatus;b. a first strap-retainer comprising: i. a hook end comprising a hook;ii. a clamp end comprising a clamp comprising: a first clamp portion having an aperture;a second clamp portion having a protrusion;a hinge configured between and coupling the first and second clamp portions together;wherein the protrusion of the second clamp portion is configured to extend at least partially through the aperture of the first clamp portion when the clamp is in a closed configuration; iii. an elastic portion extending between the hook end and the clamp end,wherein the elastic portion is elastic in a length direction, whereby the elastic portion can be stretched from an original length to a stretched length and recover substantially back to said original length,whereby in use, with the load-bearing strap extending over a cargo element and the extended-end hook coupled to a support on a first side of the cargo element and the ratchet-end hook coupled with a support on a second and opposing side to said first side of the cargo element, andwith the clamp of the strap-retainer clamped to the load-bearing strap and said load-bearing strap extending through the clamp in a closed configuration to retain the strap-retainer to the load-bearing strap, with the hook of the strap retainer coupled to a support and with the elastic portion stretched to the stretched length, the strap-retainer provides an elastic retaining force on said load-bearing strap. 10. The cargo retainer system of claim 9, comprising a second strap-retainer; wherein the first strap-retainer is clamped to the load-bearing strap the first side of the cargo element with the elastic portion of the first strap-retainer stretched to the stretched length; andwherein the second strap-retainer is clamped to said load-bearing strap on a second and opposing side to said first side of the cargo element with an elastic portion of the second strap-retainer stretched to a stretched length. 11. The cargo retainer system of claim 10, wherein the stretched length of both the first and second elastic portions is at least 20% greater than a respective original length. 12. The cargo retainer system of claim 9, wherein the ratchet apparatus comprises a ratchet. 13. The cargo retainer system of claim 9, wherein the elastic portion is configured to extend at least 100% of the original length and recover substantially back to said original length. 14. The cargo retainer system of claim 9, wherein the stretched length is at least 20% greater than the original length. 15. The cargo retainer system of claim 9, wherein the protrusion has a height that is configured to extend completely through the aperture and past an outside surface of the first clamp portion when the clamp is in a closed configuration. 16. A method of retaining a cargo element comprising the steps of: a. providing a cargo retainer system comprising: i. a load-bearing strap assembly comprising: a load-bearing strap extending from a hook-end comprisingan extended-end hook to a ratchet apparatus;a ratchet-strap extending from the ratchet apparatus to a ratchet-end hook;wherein the ratchet apparatus is configured to pull and retain the load-bearing strap from the hook-end to the ratchet apparatus; ii. a first strap-retainer comprising: a hook end comprising a hook;a clamp end comprising a clamp comprising: a first clamp portion having an aperture:a second clamp portion having a protrusion;a hinge configured between and coupling the first and second clamp portions together;wherein the protrusion of the second clamp portion is configured to extend at least partially through the aperture of the first clamp portion when the clamp is in a closed configuration; an elastic portion extending between the hook end and the clamp end,wherein the elastic portion is elastic in a length direction, whereby the elastic portion can be stretched from an original length to a stretched length and recover substantially back to said original length,b. attaching the extended-end hook of the load-bearing strap to a support on a first side of a cargo element;c. extending the load-bearing strap over said cargo element;d. attaching the ratchet-end hook to a support on a second and opposing side to said first side of said cargo element;e. tightening the load-bearing strap between the extended-end hook and the ratchet apparatus to produce a tension in the load-bearing strap and securing the load-bearing strap under said tension with the ratchet apparatus;f. attaching the first strap-retainer to the load-bearing strap by clamping the clamp around a portion of the load-bearing strap, wherein the load-bearing strap extends through the clamp;g. extending the elastic portion of the first strap-retainer to a stretched length and attaching the hook of the first strap-retainer to a support; whereby in use, the first strap-retainer provides an elastic retaining force on said load-bearing strap when the cargo element shifts during transport. 17. The method of retaining a cargo element of claim 16, further comprising the steps of: providing a second strap-retainer;attaching the second strap-retainer to the load-bearing strap by clamping the clamp around a portion of the load-bearing strap, wherein the load-bearing strap extends through a clamp of the second strap-retainer; extending an elastic portion of the second strap-retainer to a stretched length and attaching a hook of the second strap-retainer to a support;whereby in use, the first and second strap-retainers provide an elastic retaining force on said load-bearing strap when the cargo element shifts during transport. 18. The method of retaining a cargo element of claim 17, wherein a stretched length of both the first strap-retainer and second strap-retainer elastic portions is at least 20% greater than respective original lengths. 19.
