Abstract

A swiveling seat comprises a seat bottom, a swivel mechanism and a swivel resistance system. The swivel mechanism allows the seat bottom to rotate at least partially around a first axis of rotation. The swivel resistance system may include a first member that rotates with the swivel mechanism, a second member that is fixedly positioned relative to the swiveling of the swivel mechanism and an operator adjustable resistance control that is operated by the vehicle operator to bias the second member into the first member so as to vary the resistance required to swivel the operator's seat.
