Active suspension seat and vehicle operation interlocks

1. An apparatus for actively suspending a seat in a motor vehicle comprising:

a swivel enabling the seat to be pivoted about a vertical axis towards and away from an appropriate position for the seat to be used by a person when driving a vehicle;

a brake;

a controller coupled to the brake to cause the brake to inhibit the seat from being pivoted away from the appropriate position in response to receiving an indication that the vehicle is in motion, and

at least one controllable actuator coupled to the controller and operated by the controller to actively control motion of the seat in at least one degree of freedom of motion.

2. The apparatus of claim 1 , wherein motion of the seat is actively controlled in a rotational degree of freedom.

3. The apparatus of claim 2 , wherein:

the rotational degree of freedom is rotation about a horizontal axis; and

the swivel is interposed between a floor of the vehicle and the at least one actuator.

4. The apparatus of claim 3 , wherein the controller ceases to operate the at least one actuator to actively control motion of the seat in response to the seat being pivoted away from the appropriate position.

5. The apparatus of claim 1 , wherein the swivel comprises a slip ring to convey electric power from the vehicle to another portion of the seat.

6. The apparatus of claim 5 , wherein the slip ring further conveys a wired network of the vehicle to the seat controller.

7. The apparatus of claim 5 , wherein the another portion of the seat is one of a set consisting of the brake and an actuator to actively suspend the seat.

8. The apparatus of claim 1 , wherein the swivel comprises a tube-in-tube slip fitting to convey pressurized gas from the vehicle to another portion of the seat.

9. The apparatus of claim 1 , wherein:

the seat further comprises an accelerometer carried by a portion of the seat fixed to structure of the vehicle;

the controller comprises a processing device and a storage storing a sequence of instructions executed by the processing device;

wherein the processing device is caused by the sequence of instructions to monitor the accelerometer to detect an acceleration consistent with the vehicle being in motion; and

wherein the indication that the vehicle is in motion is the acceleration consistent with the vehicle being in motion.

10. The apparatus of claim 1 , wherein:

the controller comprises a network interface, a processing device, and a storage storing a sequence of instructions executed by the processing device;

wherein the processing device is caused by the sequence of instructions to operate the network interface to monitor a network of the vehicle for data from a component of the vehicle indicative of the vehicle being in motion; and

wherein the indication of the vehicle being in motion is the data from a component of the vehicle indicative of the vehicle being in motion.

11. A method of actively suspending a seat of a motor vehicle comprising:

awaiting an indication that the vehicle is in motion;

in response to receiving the indication, operating a brake of an active suspension seat to prevent the seat from pivoting on a swivel of the seat away from an appropriate position for use of the seat while driving the vehicle, and

automatically operating via the controller a controllable actuator that actively controls motion the seat in at least one degree of freedom.

12. The method of actively suspending a seat of claim 11 , wherein awaiting the indication comprises monitoring an accelerometer carried by a portion of the seat fixed to structure of the vehicle to detect an acceleration consistent with the vehicle being in motion.

13. The method of actively suspending a seat of claim 11 , wherein awaiting the indication comprises operating a network interface of a seat controller of the active suspension seat to monitor a network of the vehicle for data from a component of the vehicle indicative of the vehicle being in motion.

14. The method of actively suspending a seat of claim 11 , further comprising:

monitoring a sensor to detect whether the seat is currently in the appropriate position for use in driving; and

in response to receiving the indication and detecting that the seat is not currently in the appropriate position for use in driving, disabling provision of active control of seat motion by ceasing to operate the controllable actuator.

15. The method of actively suspending a seat of claim 11 , further comprising:

monitoring a sensor to detect whether the seat is currently in the appropriate position for use in driving; and

in response to receiving the indication and detecting that the seat is not currently in the appropriate position for use in driving, operating a component of a user interface to provide one of a set of alerts consisting of an audible alert that the seat is not in the appropriate position and a visual alert that the seat is not in the appropriate position.

16. The method of actively suspending a seat of claim 11 , further comprising:

monitoring a sensor to detect whether the seat is currently in the appropriate position for use in driving; and

in response to receiving the indication and detecting that the seat is not currently in the appropriate position for use in driving, operating a network interface to signal a component of the vehicle to provide one of a set of alerts consisting of an audible alert that the seat is not in the appropriate position and a visual alert that the seat is not in the appropriate position.

17. The method of actively suspending a seat of claim 11 , further comprising:

monitoring a sensor to detect whether the seat is currently in the appropriate position for use in driving;

operating a network interface to monitor a network of the vehicle for data from a component of the vehicle indicative of a manually-operable control of the vehicle being operated to cause the vehicle to be in motion; and

in response to receiving data indicative of a manually-operable control of the vehicle being operated to cause the vehicle to be in motion and detecting that the seat is not currently in the appropriate position for use in driving, operating the network interface to signal a component of the vehicle to act to prevent the vehicle from being caused to be in motion.

18. The method of actively suspending a seat of claim 11 , further comprising signaling a television carried within the vehicle to refrain from displaying entertainment channels in response to receiving the indication.

19. The method of actively suspending a seat of claim 18 , further comprising signaling the television to display an image provided by a camera disposed on the vehicle and providing a view to the rear of the vehicle in response to receiving the indication.

20. The method of actively suspending a seat of claim 11 , wherein the one degree of freedom is a rotation about a horizontal axis.
