ABSTRACT:
A chair seat mounting device comprises a platelike support bracket that can be fastened to a chair base and a mounting plate that can be fastened to the underside of the chair seat. The plate automatically tilts forward on an axle on the bracket when the person sitting in the chair leans forward and his or her weight overcomes a spring mechanism that yieldably restrains the seat in the normal, upright position.
