Abstract

The present invention includes a vehicle seat having a seat portion and a seatback. The vehicle seat further includes a plurality of air bladders disposed in the seat portion and a plurality of air bladders disposed in the seatback. The air bladders are configurable between fully inflated condition, fully deflated condition, and plurality of semi-inflated conditions. A controller is configured to control air bladder inflation, wherein the air bladders deflate to the fully deflated condition in response to an access signal received by the controller. The controller is further configured to control the seat position with regards to vertical and horizontal positions to provide greater access to the vehicle interior when entering or exiting the vehicle.

Claims

1. A vehicle seat, comprising:

a track assembly and a seat height adjustment mechanism coupled to the vehicle seat;

a plurality of air bladders disposed in the vehicle seat;

a controller configured to control the air bladders and a seat position; and

wherein the air bladders deflate to a fully deflated condition and the vehicle seat moves to a rearward-most and lower-most position in response to an access signal received by the controller.

2. The vehicle seat of claim 1, wherein the vehicle seat includes a seat portion coupled to the track assembly and the seat height adjustment mechanism.

3. The vehicle seat of claim 2, wherein the vehicle seat includes a seatback operably coupled to the seat portion.

4. The vehicle seat of claim 3, wherein the plurality of air bladders includes a plurality of air bladders disposed in the seat portion.

5. The vehicle seat of claim 4, wherein the plurality of air bladders further includes a plurality of air bladders disposed in the seatback.

6. The vehicle seat of claim 5, wherein each air bladder of the plurality of air bladders disposed in the seat portion and the plurality of air bladders disposed in the seatback are further configurable between a fully inflated condition and a plurality of semi-inflated conditions.

7. The vehicle seat of claim 1, wherein the vehicle seat is disposed in a motor vehicle having an ignition switch interfaced with the controller, and further wherein the access signal is received by the controller when the ignition switch is in an off condition.

8. A vehicle seat configuration system, comprising:

a vehicle seat operable between a support condition having a first vertical position and a first horizontal position, and an access condition having a second vertical position and a second horizontal position;

a plurality of air bladders disposed in the vehicle seat, wherein the air bladders are configured to deflate when the vehicle seat is in the access condition; and

a controller configured to move the vehicle seat to the access condition from the support condition in response to an access signal.

9. The vehicle seat configuration system of claim 8, wherein the second vertical position is spaced downwardly from the first vertical position, and the second horizontal position is spaced rearwardly from the first horizontal position.

10. The vehicle seat configuration system of claim 9, wherein the plurality of air bladders is disposed in a seatback of the vehicle seat.

11. The vehicle seat configuration system of claim 10, wherein the plurality of air bladders is disposed in a seat portion of the vehicle seat.

12. The vehicle seat configuration system of claim 8, wherein the vehicle seat is disposed in a motor vehicle having an ignition switch interfaced with the controller, and further wherein the access signal is received by the controller when the ignition switch is in an off condition.

13. A vehicle seat, comprising:

a seat portion and a seatback;

a plurality of air bladders disposed in the seat portion, wherein the air bladders are configurable between a fully inflated condition, a fully deflated condition, and a plurality of semi-inflated conditions therebetween; and

a controller configured to control air bladder inflation, wherein select air bladders deflate to the fully deflated condition in response to an access signal received by the controller.

14. The vehicle seat of claim 13, including:

a track assembly coupled to the vehicle seat for movement between fore and aft positions, including a rearward-most position along the track assembly.

15. The vehicle seat of claim 14, including:

a seat height adjustment mechanism coupled to the vehicle seat and configured to move the vehicle seat between upper-most and lower-most positions and a plurality of intermediate positions therebetween.

16. The vehicle seat of claim 15, wherein the vehicle seat is configured to move to the rearward-most position by the controller when the access signal received by the controller.

17. The vehicle seat of claim 16, wherein the vehicle seat is configured to move to the lower-most position by the controller when the access signal received by the controller.

18. The vehicle seat of claim 17, including:

a plurality of air bladders disposed in the seatback, wherein the air bladders disposed in the seatback are configurable between a fully inflated condition, a fully deflated condition, and a plurality of semi-inflated conditions therebetween, and further wherein the air bladders disposed in the seatback deflate to the fully deflated condition when the access signal is received by the controller.

19. The vehicle seat of claim 18, wherein the vehicle seat is disposed in a motor vehicle having an ignition switch interfaced with the controller, and further wherein the access signal is received by the controller when the ignition switch is in an off condition.

20. The vehicle seat of claim 13, including:

a plurality of air bladders disposed in the seatback, wherein the air bladders disposed in the seatback are configurable between a fully inflated condition, a fully deflated condition, and a plurality of semi-inflated conditions therebetween, and further wherein the air bladders disposed in the seatback deflate to the fully deflated condition when the access signal is received by the controller.
