Abstract
Abstract A control station for a vehicle adapted to be driven alternately in forward and reverse directions by a seated driver. A swivel seat allows for horizontal rotation about an upright axis and is mounted to the vehicle on shock-absorbing suspension means. A foot rest is fixed relative to the swivel rotation of the seat, providing the driver with the capability of controlling the swivelling of the seat by foot pressure while the vehicle is being driven. Additional foot and hand controls are mounted to the control station such that they rise and fall with the seat of the control station.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
A control station for use by a driver in a vehicle adapted to be driven alternately in forward and reverse directions, said control station comprising: a seat mounted for swivel rotation about an upright axis by means comprising a shock-absorbing suspension, said axis extending substantially through the center of gravity of the seated driver, said seat being free to swivel while the vehicle is in motion; foot rest means fixed relative to the swivel rotation of the seat for facilitating controlled swivelling of the seat by the driver's foot pressure while the vehicle is being driven; and foot controls adjacent said foot rest means and extending around said axis such that they may be operated at all operational rotational positions of the seat, said foot controls and said foot rest means being mounted to rise and fall with the seat.
Claim 2
Dependent Claim
140 words
A control station for use by a driver in a vehicle adapted to be driven alternately in forward and reverse directions, said control station comprising: a seat mounted for swivel rotation about an upright axis by means comprising a shock-absorbing suspension, said axis extending substantially through the center of gravity of the seated driver, said seat being free to swivel while the vehicle is in motion; foot rest means fixed relative to the swivel rotation of the seat for facilitating controlled swivelling of the seat by the driver's foot pressure while the vehicle is being driven; and foot controls adjacent said foot rest means and extending around said axis such that they may be operated at all operational rotational positions of the seat, said foot controls and said foot rest means being mounted to rise and fall with the seat.
Claim 3
Dependent Claim
26 words
The control station of claim 1 wherein hand controls are carried by said station, said hand controls comprising steering and vehicle joysticks mounted on the seat.
Claim 4
Dependent Claim
22 words
The control station of claim 1 wherein said foot controls are mounted around said axis and comprise arcuately-shaped accelerator and brake pedals.
Claim 5
Dependent Claim
51 words
The control station of claim 1 wherein said suspension means comprises a hydraulic cylinder connected to an accumulator pressurized to variably control the dampened resilience of said suspension means when vertical movement of said seat causes hydraulic fluid to flow through a restricting orifice element in the connection to said cylinder.
Claim 6
Dependent Claim
26 words
The control station of claim 1 wherein steering means for steering said vehicle are mounted to rise and fall with said seat and said foot controls.
