Automatic headrest adjustment control system for a vehicle seat assembly
First Claim
1. A control system for automatically adjusting the position of a headrest of a vehicle seat assembly, the control system comprising:
- at least one occupancy sensor adapted to be disposed in the seat assembly for detecting the presence of a passenger in the seat assembly;
at least one passenger position sensor adapted to be disposed proximate to the headrest for detecting the position of a passenger'"'"'s head relative to the position of the headrest;
a control module configured to communicate with the at least one occupancy sensor and the at least one passenger position sensor for receiving output signals, wherein the control module is configured to interpret output signals generated by the sensors and to generate a control signal to position the headrest; and
at least one drive motor adapted to be operatively connected to the headrest for positioning the headrest based on the control signal received from the control module.

Abstract
A control system and method for automatically adjusting the position of a headrest of a seat assembly for a vehicle. The control system includes at least one occupancy sensor disposed within the seat assembly for detecting the presence of a passenger in the seat assembly and at least one passenger position sensor disposed proximate to the headrest for detecting the position of a passenger'"'"'s head relative to the position of the headrest. A control module monitors the output of the at least one occupancy and position sensors and generates a control signal instructing the at least one drive motor to reposition the headrest to adjust to the presence and position of the passenger in the seat.

9. A seat assembly for use in a passenger compartment of a vehicle, the seat assembly comprising:
-
a seat bottom;
a seat back mounted to the seat bottom;
a headrest adjustably connected to and disposed adjacent an upper portion of the seat back; and
an automatic headrest adjustment control system, the control system including at least one occupancy sensor disposed within the seat bottom for detecting the presence of a passenger in the seat assembly, at least one passenger position sensor disposed proximate to the headrest for detecting the position of a passenger'"'"'s head relative to the position of the headrest, a control module in communication with the at least one occupancy sensor and the at least one passenger position sensor for receiving output signals of the sensors, wherein the control module generates a control signal to position the headrest based on the output signals, and at least one drive motor operatively connected to the headrest for positioning the headrest based on the control signal received from the control module. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of automatically adjusting the position of a headrest of a vehicle seat assembly, the method comprising:
-
monitoring output signals from at least one occupancy sensor and at least one passenger position sensor to detect the presence and position of a passenger in the vehicle seat assembly;
generating a control signal based on the output signals for instructing at least one drive motor to position the headrest; and
positioning the headrest with the at least one drive motor based on the control signal between at least one position in proximity to the passenger'"'"'s head and a stored position. - View Dependent Claims (19, 20, 21)
