Motor-driven passenger seat and method for adjusting the same

A method for readjusting the range of motion for a motor-driven passenger seat the method comprising the steps of:

• engaging motor-driven actuators of the passenger seat to the end of a stroke;
• determining operating positions of the motor-driven actuators;
• detecting the end of the stroke;
• and
• automatically adjusting Preference positions based on the operating positions determined when the end of stroke is detected.

A control mechanism for actuating a power seat, comprising:

• a plurality of actuators allowing a range of motions of the power seat, the range of motions having at least a mechanical limit range of motion and a soft limit range of motion, the soft limit having a predetermined range of motion within the mechanical limit range;
• a position device for determining operating positions of the actuators;
• a sensor for detecting an end of a stroke of the mechanical limit;
• and
• a controller for controlling the operating position of the actuators, the controller having an adjusting mode for automatically adjusting the range of motion of the soft limit based on the operating positions determined when the end of stroke is detected.
