Abstract

A seat assembly is provided with a translatable seat cushion, a pivotal seat back, and a head restraint adapted to be mounted for translation adjacent the seat back. An actuator is operably connected to at least one of the seat cushion and the seat back for adjustment of a plurality of settings of the seat assembly. A controller is in electrical communication with the actuator and is configured to receive input indicative of occupant anthropometry data, current physical condition and/or activity level, compare the input with predetermined data ranges, and adjust at least one of the plurality of settings of the actuator to a predetermined setting based on the predetermined range. A computer-program product is programmed for automatically adjusting a seat assembly. A method for adjusting a seat assembly receives anthropometry data for an occupant.

Claims

1. A seat assembly comprising:

a seat cushion adapted to be mounted for translation;

a seat back adapted to be pivotally mounted adjacent the seat cushion;

at least one actuator operably connected to at least one of the seat cushion and the seat back for adjustment of at least one of a plurality of settings of the seat assembly;

a controller in electrical communication with the at least one actuator and configured to;

receive input indicative of occupant anthropometry data,

select a predetermined data range associated with the input indicative of occupant anthropometry data, and

adjust at least one of the plurality of settings of the seat assembly to a predetermined setting based on the selected predetermined data range;

wherein the at least one actuator comprises;

a compressor in electrical communication with the controller,

a plurality of valves in electrical communication with the controller and in fluid communication with the compressor, and

a plurality of air bladders in fluid communication with the plurality of valves;

wherein the plurality of air bladders comprises individually inflatable left side air bladders and individually inflatable right side air bladders;

a plurality of sensors operably connected to at least one of the seat cushion, the seat back, and a head restraint to detect a seating position of an occupant; and

wherein the plurality of sensors comprises;

at least one left side sensor, and

at least one right side sensor;

wherein the controller is further configured to;

output a questionnaire to a media device, and

receive the input indicative of the occupant anthropometry data from the media device in response to the questionnaire;

wherein the at least one actuator is manually adjustable;

wherein the input indicative of occupant anthropometry data comprises at least one of occupant height and occupant weight and

wherein the controller is further configured to;

receive input indicative of a manual adjustment to the at least one actuator,

compare the manual adjustment to biomechanically optimized data, and

adjust the at least one actuator to a setting corresponding to a predetermined range of biomechanically optimized data associated with the occupant anthropometry data in response to the input indicative of the manual adjustment.

2. The seat assembly of claim 1 wherein the controller is further configured to:

receive input indicative of current physical condition; and

adjust at least one of the plurality of settings of the at least one actuator to a predetermined setting based on a predetermined data range associated with the current physical condition.

3. The seat assembly of claim 1 wherein the controller is further configured to:

receive input indicative of activity level; and

adjust at least one of the plurality of settings of the at least one actuator to a predetermined setting based on a predetermined data range associated with the activity level.

4. The seat assembly of claim 1 wherein the predetermined data ranges comprise biomechanically optimized data.

5. The seat assembly of claim 1 wherein the predetermined data ranges comprise a table of anthropometry data ranges collected from a plurality of surveyed persons.

6. The seat assembly of claim 1 wherein the at least one actuator comprises a motor-driven height adjustment mechanism.

7. The seat assembly of claim 1 wherein the at least one actuator comprises a motor-driven fore-aft adjustment mechanism.

8. The seat assembly of claim 1 wherein the at least one actuator comprises a motor-driven head restraint adjustment mechanism.

9. The seat assembly of claim 1 wherein the at least one actuator comprises:

a motor-driven height adjustment mechanism;

a motor-driven fore-aft adjustment mechanism; and

a motor-driven head restraint adjustment mechanism.

10. A computer-program product embodied in a non-transitory computer readable medium that is programmed for automatically adjusting a seat assembly, the computer-program product comprising instructions for:

receiving input indicative of occupant anthropometry data;

selecting a predetermined data range associated with the input indicative of occupant anthropometry data; and

adjusting an actuator to a predetermined setting based on the selected predetermined range;

outputting a questionnaire to a media device;

receiving the input indicative of the occupant anthropometry data from the media device in response to the questionnaire;

wherein the input indicative of occupant anthropometry data comprises at least one of occupant height and occupant weight

receiving input indicative of a manual adjustment to the actuator;

comparing the manual adjustment to biomechanically optimal data; and

adjusting the actuator to another predetermined setting based on the biomechanically optimal data associated with the occupant anthropometry data in response to the input indicative of the manual adjustment.

11. A method for adjusting a seat assembly comprising steps of:

obtaining predetermined data ranges from biomechanically optimized data provided by a posture expert;

receiving anthropometry data for an occupant;

selecting a predetermined data range associated with the anthropometry data for the occupant; and

adjusting the seat assembly to a preferred seating adjustment for the selected predetermined data range; and

wherein the anthropometry data comprises at least one of occupant height and occupant weight.
