VEHICLE SEATING SYSTEM AND METHOD FOR REDUCING FATIGUE WITH DYNAMIC ACTUATOR MOVEMENT
First Claim
Patent Images
1. A vehicle seating system for reducing user fatigue, comprising:
- a seat having a seat back and a seat bottom;
a first powered seat adjustment actuator to slowly move said seat back incline slowly forwards and slowly backwards between at least first seat-back position and a second seat-back position, said slow movement occurring while the vehicle is moving;
a first sensor for sensing a first series of speed parameters from said seat back, said first powered seat actuator, or both; and
,a controller for automatically controlling movement of said first powered seat adjustment actuator while the vehicle is moving, wherein said controller dynamically adjusts the speed of movement of said seat back based on comparing at least one speed parameter from said first series of speed parameters with a first smooth movement speed projection and dynamically adjusting a first control signal to said first powered seat adjustment actuator to converge the speed of movement of said seat back, said first powered seat adjustment actuator, or both toward or equal to said first smooth movement speed projection.

Abstract
A vehicle seating system is disclosed having a seat and at least one powered seat adjustment actuator for altering the seating position formed by the seat. A controller dynamically adjusts the speed of movement of said seat back based on comparing at least one speed parameter from said first series of speed parameters with a first smooth movement speed projection and dynamically adjusting a first control signal to said first powered seat adjustment actuator to converge the speed of movement toward or equal to said first smooth movement speed projection.
