The seat swivel includes a swivel assembly having a swivel plate rotatably supported between a pair of fixed plates, the swivel plate being adapted to be affixed to the seat and the fixed plates being adapted to be affixed to a seat base. The seat swivel further includes a brake assembly having a mechanism for releasably retaining the seat in any one of the infinite number of positions when the seat is subjected to a first dynamic impact loading, the mechanism being either mechanically or electrically actuated, the mechanism being adapted to withstand a dynamic impact loading of up to about 16 g in at least one rotational position of the seat.
