Abstract
A chair adapted to continuously discharge static electricity has conductive fabric (80, 98) on backrest and seat cushions (18, 14) grounded through conductive plates (84, 100) and staples (88), bolts (34, 68) and T-nuts (62). The backrest bolts (34) are electrically connected to each chair base (16) through a metal bracket (40). The seat bolts (68) are connected directly to the chair base (16). A conductive contact spring (120) is secured to the bottom of a spindle (114) to maintain electrical contact between the spindle (114) and a hub tube (124). A drag cable assembly (140) maintains electrical communication between the base (16) and a floor surface.
