Abstract

A vehicle includes a seat adjustable fore and aft and a lock-out feature configured to render the vehicle inoperable when the seat is rearward of a predetermined point in the vehicle. The lock-out feature is preferably configured to prevent movement of the seat rearward of the predetermined point when at least one predetermined vehicle condition exists. A corresponding method is also provided.

Claims

1. A vehicle comprising:

a seat having a lower seat portion and a seatback portion wherein the seat is selectively movable fore and aft within the vehicle; and

a lock-out system sufficiently configured to render the vehicle inoperable when the lower seat portion is located rearward of a predetermined point.

2. The vehicle of claim 1, further comprising a transmission selector movable between a plurality of positions including a first position corresponding to a park transmission mode and a second position corresponding to a drivable transmission mode;

and a transmission selector lock operatively connected to the transmission selector to selectively lock the transmission selector in the first position and thereby render the vehicle inoperable;

wherein the lock-out system is configured such that the transmission selector lock locks the transmission selector in the first position when the lower seat portion is rearward of the predetermined point.

3. The vehicle of claim 1, further comprising an ignition switch switchable between an on position and an off position;

and an ignition switch lock operatively connected to the ignition switch to selectively lock the ignition switch in the off position and thereby render the vehicle inoperable;

wherein the lock-out system is configured such that the ignition switch lock locks the ignition switch in the off position when the seat is rearward of the predetermined point.

4. The vehicle of claim 1, wherein the vehicle includes a powerplant for supplying motive power to propel the vehicle, and a controller operatively connected to the powerplant and sufficiently configured to render the powerplant inoperable when the seat is rearward of the predetermined point.

5. The vehicle of claim 1, wherein the lock-out system is sufficiently configured to prevent movement of the lower seat portion rearward of the predetermined point when a predetermined vehicle condition exists.

6. The vehicle of claim 5, wherein the lock-out system includes a sensor configured to detect whether the predetermined vehicle condition exists.

7. The vehicle of claim 6, further comprising a transmission selector movable between a plurality of positions including a first position corresponding to a park transmission mode and a second position corresponding to a drivable transmission mode;

wherein the sensor is sufficiently configured and positioned with respect to the transmission selector to detect whether the transmission selector is in the second position; and

wherein the predetermined vehicle condition is the transmission selector being in the second position.

8. The vehicle of claim 6, further comprising an ignition switch switchable between an on position and an off position;

wherein the sensor is sufficiently configured and positioned with respect to the ignition switch to detect whether the ignition switch is in the on position; and

wherein the predetermined vehicle condition is the ignition switch being in the on position.

9. The vehicle of claim 5, wherein the seat is a front sear, and wherein the vehicle includes a rear seat rearward of the front seat;

and wherein the front seat is selectively movable such that at least a portion of the front seat is rearward of at least a portion of the rear seat.

10. A method comprising:

determining whether a lower seat portion of a vehicle seat is positioned rearward of a predetermined point, the vehicle seat being selectively movable fore and aft within a vehicle; and

rendering the vehicle inoperable in response to the lower seat portion being positioned rearward of the predetermined point.

11. The method of claim 10, wherein the vehicle includes a transmission selector movable between a plurality of positions including a first position corresponding to a park transmission mode and a second position corresponding to a drivable transmission mode, and wherein said rendering the vehicle inoperable includes locking the transmission selector in the first position.

12. The method of claim 10, wherein the vehicle includes an ignition switch switchable between an on position and an off position, and wherein said rendering the vehicle inoperable includes locking the ignition switch in the off position.

13. The method of claim 10, wherein the method further comprises sensing the presence or existence of a predetermined vehicle condition;

and preventing movement of the lower seat portion rearward of the predetermined point in response to the presence or existence of said predetermined condition.

14. The method of claim 13, wherein the vehicle includes a transmission selector movable between a plurality of positions including a first position corresponding to a park transmission mode and a second position corresponding to a drivable transmission mode;

and wherein said predetermined condition is the transmission selector being in the second position.

15. The method of claim 13, wherein the vehicle includes an ignition switch switchable between an on position and an off position;

and wherein said predetermined condition is the ignition switch being in the on position.

16. The method of claim 13, wherein the vehicle seat is operatively connected to a seat track on which the vehicle seat is movable fore and aft, and wherein said preventing the vehicle seat from moving rearward of the predetermined point includes obstructing movement of the vehicle seat along the seat track.

17. A vehicle comprising:

a seat having a lower seat portion and a seatback portion wherein the seat is selectively movable fore and aft within the vehicle; and

a lock-out system sufficiently configured to

render the vehicle inoperable when the lower seat portion is located rearward of a predetermined point, and

prevent movement of the lower sear portion rearward of the predetermined point when a predetermined vehicle condition exists.
