Abstract: The present invention provides a resilient seat belt extension device comprising: a female receptacle adapted to engage a seat belt system's male buckle; a male buckle adapted to engage a seat belt system's female receptacle; and a resilient connector fixedly attached to the female receptacle on one end and the male buckle on another end; wherein the connector is formed by the following steps: (i) attaching ends of an elongated material together to form the connector with two layers of elongated material; (ii) placing a non-liquid compound between the two layers of elongated material wherein the compound is adapted to provide resiliency to the connector; (iii) attaching the two layers of elongated material together; and (iv) curing the compound at a predetermined temperature. The present invention also provides a method of making the above-described device.

Abstract: A cable manufacturing method includes feeding bundles of core wires into a wire tensioning apparatus, applying even tension on the fed bundles before extrusion, and extruding the evenly tensioned core wire bundles into a cable with a substantially D-shaped cross-section. Other steps include providing a cable take up spool, and winding the extruded cable in overlapping layers onto the take up spool such that overlapping D-shaped cross-sections of wound cable are lined up directly on top of each other in a controlled fashion to prevent cable deformation.
