Claim:
A frame system, comprising: a bent tubular rod; an interface joint molded over the bent tubular rod, wherein a section of the bent tubular rod having the interface joint molded thereon includes a dimple to receive molding material of the interface joint to secure the interface joint to the bent tubular rod by molding material of the interface joint flowing into the dimple; wherein a hollow cross face structural member connects to a first portion of the bent tubular rod through the interface joint being molded over the bent tubular rod and the hollow cross face structural member, wherein the bent tubular rod is continuous through the interface joint, and wherein the hollow cross face structural member couples the first portion of the bent tubular rod to a second portion of the bent tubular rod, and wherein the hollow cross face structural member includes a solid plug filling an interior of an end of the hollow cross face structural member that is molded in the interface joint, wherein the solid plug is configured to prevent mold material from entering the hollow cross face structural member during the interface joint molding process.
