ABSTRACT:
An improved seat base for a swivel type seat in which the base's seat support and pedestal are connected together in swivel relation by a thrust bearing of inverted conical configuration. In preferred form, a latch dog is movable between a latch position defined by a latch seat in the outer bearing collar for preventing swivel type rotation of the seat, and a release position where the latch dog is withdrawn from the latch seat into the interior of the thrust bearing for allowing swivel type rotation of the seat. The latch dog is pivotable on a horizontal axis oriented above the thrust bearing between those two positions through a latch post in the inner bearing collar by use of a lift arm connected thereto, the lift arm having a handle located adjacent to the seat's front edge.
