Abstract

A vehicle seat assembly is provided with a seat bottom pivotally mounted to an actuator and a vehicle floor. A controller is in electrical communication with the actuator and programmed to receive input indicative of a seating position angle, and input indicative of a potential vehicle impact. A signal is output to the actuator to pivot the seat to a nearest one of the plurality of predefined seat orientations if the seating position is not one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received. The signal is not output to the actuator if the seating position is one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received. The plurality of predefined seat orientations is offset radially at sequential increments.

First claim

What is claimed is:

1. A vehicle seat assembly comprising:
a seat bottom adapted to be pivotally mounted to a vehicle floor;
an actuator in cooperation with the seat bottom and the vehicle floor to pivot the seat bottom relative to the vehicle floor; and
a controller in electrical communication with the actuator and programmed to:
receive input indicative of a potential vehicle impact,
receive input indicative of a seating position angle,
determine if the seating position angle is one of a plurality of predefined seat orientations, and
output a signal to the actuator to pivot the seat assembly to a nearest one of the plurality of predefined seat orientations in response to receiving the input indicative of the potential vehicle impact.

2. The vehicle seat assembly of claim 1 wherein the controller is further programmed to:
receive input indicative of a direction of the potential vehicle impact;
determine a mitigated risk seating orientation for the direction of the potential vehicle impact; and
output the signal to the actuator to pivot the seat assembly to the mitigated risk seating orientation in response to receiving the input indicative of the potential vehicle impact and the input indicative of the direction of the potential impact.

3. The vehicle seat assembly of claim 1 wherein the controller is further programmed to output the signal to the actuator if the seating position angle is not one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received.

4. The vehicle seat assembly of claim 3 wherein the controller is further programmed to not output the signal to the actuator if the seating position angle is one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received.

5. The vehicle seat assembly of claim 1 wherein the plurality of predefined seat orientations is offset radially at sequential increments.

6. The vehicle seat assembly of claim 1 wherein the plurality of predefined seat orientations includes a forward-facing seat orientation and a rearward-facing seat orientation.

7. The vehicle seat assembly of claim 6 wherein the plurality of predefined seat orientations includes at least one laterally-facing seat orientation.

8. The vehicle seat assembly of claim 1 wherein the plurality of predefined seat orientations is further defined as a radial array with increments of forty-five degrees.

9. An autonomous vehicle comprising:
a land vehicle with a vehicle floor;
at least one impact sensor;
a controller in cooperation with the land vehicle to control travel of the land vehicle, and in cooperation with the at least one impact sensor to output a signal indicative of a potential vehicle impact; and
at least one seat assembly according to claim 1 mounted to the vehicle floor, wherein the seat assembly controller is in communication with the autonomous vehicle controller.

10. A vehicle seat assembly comprising:
a seat bottom adapted to be pivotally mounted to a vehicle floor;
an actuator in cooperation with the seat bottom and the vehicle floor to pivot the seat bottom relative to the vehicle floor; and
a controller in electrical communication with the actuator and programmed to:
receive input indicative of a seating position angle,
receive input indicative of a potential vehicle impact,
determine if the seating position angle is one of a plurality of predefined seat orientations,
output a signal to the actuator to pivot the seat to a nearest one of the plurality of predefined seat orientations if the seating position is not one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received, and
not output the signal to the actuator if the seating position is one of the plurality of predefined seat orientations when the input indicative of the potential vehicle impact is received; and

wherein the plurality of predefined seat orientations is offset radially at sequential increments.

11. The vehicle seat assembly of claim 1 wherein the plurality of predefined seat orientations is further defined as a finite number of predefined seat orientations designed to withstand impact conditions.

12. The vehicle seat assembly of claim 11 wherein the plurality of predefined seat orientations is further defined as a radial array with increments of forty-five degrees.
