Abstract
A conductive strap for tethering personnel to electrical ground comprises a stretchable band of an elastomeric non-conductive fabric for resiliently embracing a body member in a closed loop. At least one row of a continuous conductive thread is embroidered to the interior surface of the band by a line of stitching which includes a non-conductive thread component penetrating through the fabric from the outside and interlocking with the interior conductive thread component, preferrably sewn in a zig-zag pattern. The conductive thread is coupled to a clasp for electrical connection to ground through a cable tether.
