First Claim
Patent Images
1. A vehicle seating system for reducing user fatigue, comprising:
- a seat mountable in a vehicle having a seat back and a seat bottom;
at least two powered seat adjustment actuators including a seat back actuator to incline the seat back and a seat bottom actuator to tilt the seat bottom, each movable between a respective first position and a respective second position, for altering the seating position formed by said seat to reduce positional fatigue;
wherein said powered seat adjustment actuators reposition said seat to different seating positions with a slow movement average of less than about 10 centimeters per second between said first positions and said second positions; and
an electrical controller for activating movement of said powered seat adjustment actuators, said electrical controller having a control period;
wherein said controller automatically activates said slow movement average of said powered seat adjustment actuators between said first and said second positions to incline the seat back forward and said slow movement average of said seat bottom actuator to tilt the seat bottom upward, and automatically activates said slow movement average of said seat back actuator to incline the seat back backward and said slow movement average of said seat bottom actuator to tilt the seat bottom downward to reduce positional fatigue.

Abstract
A vehicle seating system can be used within a variety of vehicles to reduce positional fatigue and other effects of long distance traveling. Such a system includes a typical vehicle seat mountable in a vehicle, at least two powered seat adjustment actuators, and an electrical controller. The actuators are moveable to alter the seating position formed by the seat, thereby reducing fatigue experienced by a vehicle traveler.

11. A vehicle seating system for reducing user fatigue, comprising:
-
a seat mountable in a vehicle having a seat back and a seat bottom; at least two powered seat adjustment actuators including a seat back actuator to incline the seat back and a seat bottom actuator to tilt the seat bottom, each movable independently of each other between a respective first position and a respective second position for altering the seating position formed by said seat to reduce positional fatigue; wherein said powered seat adjustment actuators reposition said seat to different seating positions between said first positions and said second positions; and an electrical controller for activating movement of said powered seat adjustment actuators, said electrical controller having a control period; and
,wherein said controller automatically activates said powered seat adjustment actuators between said first and said second positions to incline the seat back forward and said seat bottom actuator to tilt the seat bottom upward, and automatically activates said seat back actuator to incline the seat back backward and said seat bottom actuator to tilt the seat bottom downward to reduce positional fatigue. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for reducing vehicle user fatigue, comprising:
-
providing a seat mountable in a vehicle having a seat back and a seat bottom; providing at least two powered seat adjustment actuators including a seat back actuator to incline the seat back and a seat bottom actuator to tilt the seat bottom, each movable between a respective first position and a respective second position for altering the seating position formed by said seat to reduce positional fatigue; activating movement of said powered seat adjustment actuators with an electrical controller having a control period including at least one movement period; and said activating movement including activating at least one of said powered seat adjustment actuators to reposition said seat to different seating positions during said at least one movement period, wherein movement of said powered seat adjustment actuators includes a slow movement average of less than about ten centimeters per second from said first position to said second position; and
,wherein said controller automatically activates said powered seat adjustment actuators between said first and said second positions to incline the seat back forward and said seat bottom actuator to tilt the seat bottom upward, and automatically activates said seat back actuator to incline the seat back backward and said seat bottom actuator to tilt the seat bottom downward to reduce positional fatigue. - View Dependent Claims (20, 21, 22, 23)
