Definitions

  • the present disclosure relates generally to the field of adjustable and movable seats. More specifically, the present disclosure relates to the fieid of reconfigurable, power vehicle seats that may be configured to facilitate storage and access to the interior of a vehicle behind the seat.
  • second row seats have been provided in a variety of different configurations.
  • some seats are configured so that the seat back folds down on top of the seat cushion.
  • this configuration allows cargo to be placed on top of the folded down seatback, it generally does not provide convenient access to a third row of seats because such a seat requires the occupant to ciimb over the folded down seat, which may be burdensome in many cases.
  • Other seats are configured such that the seatback folds down over the seat cushion, and then the rear of the folded unit is rotated upward so that the seat cushion and seatback are in a generally vertical position proximate the back of the seat in front of the folded seat. While such a seat allows an occupant to more easily access the third row of seats, moving the seat from the seating position to the folded or storage position can be burdensome due to the fact that one must lift the weight of the seat to rotate it to the folded or vertical position.
  • Still other seats are configured so that the seat cushion can be rotated around the forward portion of the seat cushion into a generally vertical position proximate the back of the seat in front, and so that the seat back can be moved forward and upward (either at the same time the seat cushion is rotated forward, or after the seat cushion has been rotated forward) in a generally arc- ⁇ ke path until it rests proximate the seat cushion in a generally upright position.
  • this configuration reduces the obstacles an occupant must climb over to reach the third row of seats, it still requires the occupant to lift the seatback while moving it into the forward position. The need to lift the seat or a portion of the seat can be burdensome and inconvenient.
  • Vehicle seats such as stadium and folding seats, that may be moved along a track in a vehicle are also known.
  • a user translates the seat along a track by manually moving the seat.
  • the seat may be moved between a design position, where a vehicle occupant may sit in the seat while riding, and an EZ entry position, where the seat is moved, typically forward, so that a person may have easier access to regions of the vehicle behind the seat.
  • a spring is employed to help drive the seat forward to the EZ entry position. In this case, returning the seat toward the back (toward the design position) must be done against the spring force, and requires a larger effort to return the seat.
  • One exemplary embodiment relates to a vehicle seat including a power shuttle drive system.
  • the seat includes a seat back, a seat bottom, a track arrangement, a first carriage, and a second carriage.
  • the seat bottom is coupled to the seat back.
  • the track arrangement is configured to be coupled to the vehicle.
  • the first carriage is coupled to the seat bottom and is moveabie within the track arrangement.
  • a power shuttle drive system for use with the seat includes a carriage drive mechanism configured to move at least one of the first and second carriages within the track arrangement and in at least a first direction.
  • the power shuttle drive system may move the second carriage within the track arrangement in at least a second direction, which may be opposite the first direction, to move the seat back and seat bottom between a first design position and a second folded position.
  • FIG. 1 Another exemplary embodiment relates to a power shuttle drive system adapted to be used with a seat, the seat including a seat cushion, a seat back and a track arrangement that is configured to be coupled to a vehicle.
  • the track arrangement includes a carriage configured to be coupled to the seat cushion and moveabie within the track arrangement.
  • the power shuttle drive system that may be added to the seating system comprises a drive motor, a drive screw, a drive nut and a iatch.
  • the drive motor drives the drive screw and the drive nut is engaged with the drive screw.
  • the latch is configured to be coupled to the carriage and engages with the drive nut which causes the carriage to move within the track.
  • a power shuttle drive system is adapted to be used with an existing seat, the power shuttle drive system having a comfort adjustment feature.
  • the seat includes a seat cushion, a seat back, a track arrangement, and a carriage.
  • the track arrangement is configured to be coupled to a vehicle and the carriage is coupled to the seat and is moveabie within the track arrangement.
  • the power shuttle drive system includes a drive motor, a drive screw, a drive nut and a latch.
  • the drive motor drives the drive screw and the drive nut is engaged with the drive screw.
  • the latch is configured to be coupled to the carriage and engages with the drive nut which causes the carriage to move within the track.
  • the power shuttle drive system further includes two stops disposed on the drive nut. The stops define an adjustment space. The latch is selectively located in the adjustment space between the stops to allow the iatch and thereby the carriage to move along the track in between the stops independently of the power shuttle drive system.
