Abstract

A seat assembly is provided with a seat bottom, a seat back, and a plurality of sensors operably connected to at least one of the seat bottom and the seat back to detect a seating condition of a seated occupant. A controller is in electrical communication with the plurality of sensors. The controller is programmed to receive input from the plurality of sensors indicative of a seating condition of the seated occupant. The seating condition is compared to a predetermined seating condition. An output indicative of the predetermined seating condition is transmitted. An actuator is in electrical communication with the plurality of sensors and operably connected to at least one of the seat bottom and the seat back for adjustment of at least one of a plurality of settings of the seat assembly. The actuator is adjusted to a predetermined setting corresponding to the predetermined seating condition.

First claim

1 . A seat assembly comprising:
a seat bottom; a seat back; wherein a position of at least one of the seat bottom and the seat back is manually adjustable; a plurality of sensors operably connected to at least one of the seat bottom and the seat back to detect a seating condition and to detect manual adjustment to the seating position; and a controller in electrical communication with the plurality of sensors, the controller being programmed to:
receive input from the plurality of sensors indicative of the seating condition,
compare the seating condition to a predetermined seating condition, and
transmit an output indicative of the predetermined seating condition.

2 . The seat assembly of claim 1 wherein the input indicative of the seating condition comprises input indicative of a fore-aft position of the seat bottom.

3 . The seat assembly of claim 2 wherein the input indicative of the seating condition further comprises:
input indicative of a height position of the seat bottom;
input indicative of a tilt position of the seat bottom; and
indicative of a recline position of the seat back.

4 . The seat assembly of claim 1 wherein the input indicative of the seating condition comprises input indicative of a height position of the seat bottom.

5 . The seat assembly of claim 1 wherein the input indicative of the seating condition comprises input indicative of a tilt position of the seat bottom.

6 . The seat assembly of claim 1 wherein the input indicative of the seating condition comprises input indicative of a recline position of the seat back.

7 . The seat assembly of claim 1 wherein the plurality of sensors comprise a plurality of gyroscopic sensors.

8 . The seat assembly of claim 1 wherein the plurality of sensors comprise a plurality of six-axis sensors.

9 . The seat assembly of claim 1 wherein the plurality of sensors comprise an array of four sensors.

10 . The seat assembly of claim 1 further comprising a display in communication with the controller to display an image of the predetermined seating condition.

11 . The seat assembly of claim 1 wherein the controller is further programmed to transmit an output indicative of the seating condition.

12 . The seat assembly of claim 11 further comprising a display in communication with the controller to display an image of the seating condition and the predetermined seating condition.

13 . The seat assembly of claim 11 wherein the controller is further programmed to transmit an output indicative of at least one adjustment from the seating condition to the predetermined seating condition.

14 . The seat assembly of claim 13 further comprising a display in communication with the controller to display an image of the seating condition, the predetermined seating condition and the at least one adjustment.
