a seat mover system configured to provide means for moving the vehicle seat continuously relative to the vehicle floor from one configuration to another different configuration by varying a tilt angle, a height, and a longitudinal position of the vehicle seat in parallel relative to the vehicle floor without separate tilt angle, height, and longitudinal movements,
wherein the seat mover system includes a lift unit configured to provide means for moving a rear end of the vehicle seat relative to the vehicle floor to vary at least one of the height and the tilt angle of the vehicle seat,
wherein the lift unit includes a first mover that is configured to expand and contract radially relative to a pivot axis to cause the rear end of the vehicle seat to move radially relative to the pivot axis and a first actuator that is configured to drive expansion and contraction of the first mover.
8. The seat system of claim 7 , wherein the seat mover system includes a second lift unit configured to provide means for moving a front end of the vehicle seat relative to the vehicle floor to vary at least one of the height and the tilt angle of the vehicle seat and the second lift unit includes a second mover that is configured to expand and contract radially relative to a second pivot axis to cause the front end of the vehicle seat to move radially relative to the second pivot axis and a second actuator that is connected to the second mover and configured to drive expansion and contraction of the second mover.
9. The seat system of claim 7 , wherein the seat mover system further includes a rotator unit configured to provide means for moving the vehicle seat relative to the vehicle floor to vary at least one of the height and the longitudinal position of the vehicle seat.
10. The seat system of claim 9 , wherein the rotator unit includes a second mover arranged to move the lift unit circumferentially about the pivot axis relative to the vehicle floor and a second actuator configured to drive the second mover.
11. A seat system for use in a vehicle comprising
a vehicle seat arranged to support an occupant above a vehicle floor included in the vehicle, and
a seat mover system configured to provide means for moving the vehicle seat continuously relative to the vehicle floor from one configuration to another different configuration by varying a tilt angle, a height, and a longitudinal position of the vehicle seat in parallel relative to the vehicle floor without separate tilt angle, height, and longitudinal movements,
wherein the seat mover system includes a rotator unit configured to provide means for moving the vehicle seat relative to the vehicle floor to vary at least one of the height and the longitudinal position of the vehicle seat,
wherein the rotator unit includes a first mover arranged to move the vehicle seat circumferentially about a pivot axis relative to the vehicle floor and a first actuator configured to drive the first mover.
12. The seat system of claim 11 , wherein the seat mover system further includes a lift unit configured to provide means for moving a front end of the vehicle seat relative to the vehicle floor to vary at least one of the height and tilt angle of the vehicle seat.
13. The seat system of claim 12 , wherein the seat mover system further includes a second lift unit configured to provide means for moving a rear end of the vehicle seat relative to the vehicle floor to vary at least one of the height and the tilt angle of the vehicle seat.
14. The seat system of claim 12 , wherein the lift unit includes a second mover that interconnects the rotator unit and the vehicle seat and a second actuator connected to the second mover, the second mover is configured to expand and contract radially relative to the pivot axis to cause the front end of the vehicle seat to move radially relative to the pivot axis, and the second actuator is configured to drive expansion and contraction of the second mover.
15. A seat system for use in a vehicle comprising
a vehicle seat arranged to support an occupant above a vehicle floor included in the vehicle, and
a seat mover system including a first lift unit configured to move the vehicle seat relative to the vehicle floor to vary at least one of a height and a tilt angle of the vehicle seat, a second lift unit configured to move the vehicle seat relative to the vehicle floor to vary at least one of the height and the tilt angle of the vehicle seat, and a rotator unit configured to move the vehicle seat relative to the vehicle floor to vary at least one of the height and a translational position of the vehicle seat so as to move the vehicle seat continuously relative to the vehicle floor from one configuration to another different configuration by varying at least one of the tilt angle, the height, and the translational position of the vehicle seat simultaneously relative to the vehicle floor without separate tilt angle, height, and translational movements,
wherein the first lift unit includes a first scissor jack configured to expand and contract radially relative to a first pivot axis to cause a front end of the vehicle seat to move radially relative to the first pivot axis to vary at least one of the height and the tilt angle of the front end of the vehicle seat relative to the vehicle floor and the second lift unit includes a second scissor jack configured to expand and contract radially relative to a second pivot axis to cause a rear end of the vehicle seat to move radially relative to the second pivot axis to vary at least one of the height and tilt angle of the rear end of the vehicle seat relative to the vehicle floor.
