Abstract

A seat assembly is provided with a seat cushion and a seat back. A controller is in electrical communication with an actuator. The controller is programmed to receive a data input indicative of occupant anthropometry data. The data input is compared with predetermined data ranges. A setting of the actuator is adjusted to a predetermined setting based on the predetermined data range. A data input indicative of a selected driving mode is received by the controller. The setting of the actuator is adjusted to another predetermined setting based on the selected driving mode. The actuator includes an inflation device, side bolster air bladders, a seat back recline actuator, a tilt actuator, and a central air bladder. The driving modes include a touring mode, a sport mode and a performance mode.

First claim

What is claimed is:

1. A seat assembly comprising:
a seat cushion adapted to be adjustably mounted to a vehicle body;
a seat back 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; and
a controller in electrical communication with the at least one actuator and programmed to:
receive a data input indicative of occupant anthropometry data,
compare the data input with predetermined data ranges,
adjust at least one of the plurality of settings of the at least one actuator to a predetermined setting based on the predetermined data range,
receive a data input indicative of a selected driving mode,
adjust at least one of the plurality of settings of the at least one actuator to another predetermined setting based on the selected driving mode, and
adjust at least one of the plurality of settings of the at least one actuator in response to the selected driving mode to decrease central back support.

2. The seat assembly of claim 1 wherein the controller is further programmed to adjust at least one of the plurality of settings of the at least one actuator in response to the selected driving mode to increase bolster support.

3. The seat assembly of claim 2 wherein the at least one actuator is oriented within a side bolster region of the seat assembly.

4. The seat assembly of claim 2 wherein the at least one actuator comprises:
a pair of side bolster actuators oriented within side bolster regions of the seat cushion; and
a pair of side bolster actuators oriented within side bolster regions of the seat back.

5. The seat assembly of claim 2 wherein the at least one actuator has a range of adjustment; and
wherein the controller is further programmed to adjust the at least one actuator to at least seventy-five percent of the range of adjustment in response to the selected driving mode to increase bolster support.

6. The seat assembly of claim 2 wherein the at least one actuator comprises:
an inflation device in electrical communication with the controller; and
at least one air bladder with a range of inflation in fluid communication with inflation device; and
wherein the controller is further programmed to adjust the inflation device so that the at least one air bladder is at seventy-five percent inflation in response to the selected driving mode to increase bolster support.

7. The seat assembly of claim 2 wherein the at least one actuator has a range of adjustment; and
wherein the controller is further programmed to adjust the at least one actuator to at least ninety-five percent of the range of adjustment in response to the selected driving mode to increase bolster support.

8. The seat assembly of claim 2 wherein the at least one actuator comprises:
an inflation device in electrical communication with the controller; and
at least one air bladder with a range of inflation in fluid communication with the inflation device; and
wherein the controller is further programmed to adjust the inflation device so that the at least one air bladder is at ninety-five percent inflation in response to the selected driving mode to increase bolster support.

9. The seat assembly of claim 1 wherein the at least one actuator comprises a seat back recline actuator.

10. The seat assembly of claim 9 wherein the seat back has a pivot range relative to the seat cushion; and
wherein the controller is further programmed to decrease an angle between the seat cushion and the seat back in response to the selected driving mode to increase back support.

11. The seat assembly of claim 10 wherein the controller is further programmed to decrease the angle between the seat cushion and the seat back by five percent in response to the selected driving mode to increase back support.

12. The seat assembly of claim 1 wherein the controller is further programmed to adjust at least one of the plurality of settings of the at least one actuator in response to the selected driving mode to increase thigh support.

13. The seat assembly of claim 12 wherein the seat cushion is adapted to be pivotally mounted to the vehicle body with a pivotal range to adjust a tilt angle of the seat cushion; and
wherein the controller is further programmed to adjust the at least one actuator to raise a front of the seat cushion in response to the selected driving mode to increase thigh support.

14. The seat assembly of claim 13 wherein the controller is further programmed to adjust the at least one actuator to raise the front of the seat cushion by ten percent of the pivotal range in response to the selected driving mode to increase thigh support.

15. The seat assembly of claim 1 wherein the at least one actuator is oriented within a central back region of the seat back.

16. The seat assembly of claim 15 wherein the at least one actuator comprises:
an inflation device in electrical communication with the controller; and
at least one air bladder oriented centrally within the seat back in fluid communication with the inflation device.

17. The seat assembly of claim 16 wherein the controller is further programmed to adjust the inflation device so that the at least one air bladder is deflated in response to the selected driving mode to decrease central back support.

18. The seat assembly of claim 1 further comprising:
an inflation device;
a pair of side bolster air bladders in fluid communication with the inflation device and oriented within side bolster regions of the seat cushion, each with a range of inflation;
wherein the seat back is pivotally mounted adjacent the seat cushion with a pivot range;
a seat back recline actuator operably connected to the seat cushion and the seat back to adjust a recline angle of the seat back relative to the seat cushion; and
a pair of side bolster air bladders in fluid communication with the inflation device and oriented within side bolster regions of the seat back; and
wherein the controller is in electrical communication with the inflation device and the seat back recline actuator, and the controller is further programmed to:
receive a data input indicative of a sport driving mode,
adjust the inflation device to inflate the pair of side bolster air bladders in the seat cushion to increase bolster support in response to the sport driving mode,
adjust the inflation device to inflate the pair of side bolster air bladders in the seat back to increase bolster support in response to the sport driving mode, and
adjust the seat back recline actuator to decrease an angle between the seat cushion and the seat back in response to the sport driving mode to increase back support.

19. A seat assembly comprising:
a seat cushion adapted to be adjustably mounted to a vehicle body;
a seat back 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;
wherein the at least one actuator has a range of adjustment; and
a controller in electrical communication with the at least one actuator and programmed to:
receive a data input indicative of occupant anthropometry data,
compare the data input with predetermined data ranges,
adjust at least one of the plurality of settings of the at least one actuator to a predetermined setting based on the predetermined data range,
receive a data input indicative of
