Abstract

A method of controlling the position of a front seat having an unbelted rearmost position forward of a belted rearmost position within a vehicle is provided. The method includes determining if a seatbelt associated with the front seat is fastened and allowing movement of the front seat rearward of the unbelted rearmost position if the seatbelt is fastened. Alternately, movement of the front seat rearward of the unbelted rearmost position is prevented if the seatbelt is not fastened. The front seat may be either a driver seat or a passenger seat. A vehicle apparatus operable to carry out the disclosed method is also provided.

Claims (64)

1. A method of controlling the position of a front seat having an unbelted rearmost position forward of a belted rearmost position within a vehicle, the method comprising:

determining if a seatbelt associated with the front seat is fastened before and after determining if a transmission selector of said vehicle has moved out of the park position;

allowing movement of the front seat rearward of the unbelted rearmost position if the seatbelt is fastened; and

preventing movement of the front seat rearward of the unbelted rearmost position if the seatbelt is not fastened;

wherein said movement of the seat is controlled based upon said position of said transmission selector.

2. The method of claim 1 , wherein the front seat is a passenger seat, the method further comprising determining if the passenger seat is occupied prior to determining if said seatbelt is fastened.

3. The method of claim 1 , wherein the front seat is a passenger seat, the method further comprising:

determining if the passenger seat is rearward of the unbelted rearmost position if said seatbelt is not fastened;

moving the passenger seat to the unbelted rearmost position if the passenger seat is rearward of the unbelted rearmost position; and

maintaining the position of the passenger seat and preventing movement of the passenger seat rearward of the unbelted rearmost position if the passenger seat is at, or forward of, the unbelted rearmost position.

4. The method of claim 1 , wherein the front seat is a driver seat, the method further comprising moving the driver seat to the rearmost belted position to facilitate entry into the vehicle prior to determining if said seatbelt is fastened.

5. The method of claim 1 , wherein the front seat is a driver seat, the method further comprising:

determining if an ignition switch of said vehicle has been actuated; and

wherein it is determined if said seatbelt is fastened after said ignition switch has been actuated and before said transmission selector has been moved out of the park position.

6. The method of claim 5 , further comprising:

moving the driver seat to the furthest forward of a preselected seating position and the unbelted rearmost position if said seatbelt is unfastened; and

moving said driver seat to a preselected position at one of a position forward of, rearward of, and at the unbelted rearmost position if said seatbelt is fastened.

7. The method of claim 1 , wherein the front seat is a driver seat, the method further comprising:

determining if said transmission selector has been moved out of the park position;

determining if said seatbelt is unfastened after said transmission selector has been moved out of the park position;

determining if said driver seat is rearward of the unbelted rearmost position; and

providing a warning.

8. The method of claim 7 , further comprising moving the driver seat to the unbelted rearmost position if said seatbelt is not fastened.

9. The method of claim 8 , further comprising:

moving the driver seat to the furthest forward of a preselected seating position and the unbelted rearmost position if said seatbelt is not fastened.

10. The method of claim 7 , wherein said warning is at least one of an audible warning and a visual warning.

11. A vehicle comprising:

a front seat movably mounted and movable in a fore and aft direction with respect to the vehicle;

a power drive mechanism operable to move said front seat;

a seatbelt assembly;

a seatbelt monitoring system operable to determine if said seatbelt assembly is fastened;

wherein said front seat has an unbelted rearmost position and a belted rearmost position disposed rearward of said unbelted rearmost position;

a controller operatively connected with said power drive mechanism and said seatbelt monitoring system;

a transmission selector;

a first sensor mounted with respect to said transmission selector and in communication with said controller; and

wherein said first sensor is operable to determine the state of operation of said transmission selector;

wherein said controller is sufficiently programmed to establish whether said seatbelt is fastened from said seatbelt monitoring system and command said power drive system to move said front seat rearward of said unbelted rearmost position if said seatbelt is fastened and to move said front seat forward of said unbelted rearmost position if said seatbelt is not fastened;

wherein said movement of the seat is controlled based upon the state of operation of said transmission selector.

12. The vehicle of claim 11 , wherein said front seat is one of a driver seat and a passenger seat.

13. The vehicle of claim 11 , further comprising:

a second sensor operatively connected to said controller; and

wherein said second sensor is operable to determine the position of said front seat.

14. The vehicle of claim 11 , farther comprising:

a third sensor mounted with respect to said front seat and operatively connected to said controller;

wherein said third sensor is operable to determine whether said front seat is occupied.

15. The vehicle of claim 11 , further comprising:

a warning system operable to indicate when said controller is commanding said power drive system to move said front seat; and

wherein said warning system is at least one of a visual warning system and an audible warning system.

16. The vehicle of claim 11 , further comprising:

an ignition switch;

a fourth sensor mounted with respect to said ignition switch and in communication with said controller; and

wherein said fourth sensor is operable to determine the state of said ignition switch.

17. A method of controlling the position of a driver seat and a passenger seat each having an unbelted rearmost position forward of a belted rearmost position within a vehicle having a transmission selector and ignition switch, the method comprising:

determining if a seatbelt associated with the driver seat is fastened;

moving the driver seat to the furthest forward position of a preselected position and the unbelted rearmost position if said seatbelt associated with the driver seat is not fastened;

moving the driver seat to said preselected position either forward or rearward of said unbelted rearmost position if said seatbelt associated with the driver seat is fastened;

determining if the passenger seat is occupied;

determining if a seatbelt associated with the passenger seat is fastened;

allowing the passenger seat to be adjusted to any position if said seatbelt associated with the passenger seat is fastened;

determining if the passenger seat is rearward of the unbelted rearmost position; and

moving passenger seat to the unbelted rearmost position if the passenger seat position is rearward of the unbelted rearmost position.

18. The method of claim 17 , further comprising maintaining the position of the passenger seat and preventing movement of the passenger seat rearward of the unbelted rearmost position if the passenger seat is forward of the unbelted rearmost position.

19. The method of claim 17 , further comprising at least one of determining if the ignition switch has been actuated and determining if said transmission shifter has been moved from the park position prior to determining if said seatbelt associated with the driver seat is fastened.

20. The method of claim 17 , further comprising providing at least one of a visual and audible warning prior to moving the driver seat to the unbelted rearmost position.
