<p>A static control wristband (10) comprises a strap (12) having a first polymeric, insulative layer and a second, conductive layer (14) integrally molded with the first layer, contact means (22) for interconnection of the second layer with a conductive tether, and means for adjusting an effective length of the strap to accommodate the size of a user's limb. A third, conductive layer (24) may be included to provide a constant monitoring device in the ground path. The contact means may comprise a conventional eyelet passing through a portion of the conductive layer with a snap for connection to the tether. The insulative layer may be overmolded onto the conductive layer (14) or, where the conductive layer is also polymeric, co-molded, co-extruded in sheet or tubular form, or insert molded with the insulative layer. The tether comprises a grounding cord that may be constructed of a conductive layer surrounding a flexible strengthening member, where the strengthening member may be stranded copper wire, foil tensile wrapped around an insulative polyamide fiber thread, or a metal coated fiber. The conductive layer of the tether may be constructed of a flexible elastomer loaded with a conductive filler, and a flexible polymer insulative layer may surround the conductive layer. The tether may be formed into a coil to remove excess length during use.</p> |
