  • Patent number: 6922031
    Abstract: A door actuation system conducts or assists movement of sliding vehicle doors by connecting the door to a bi-directional motor via one or more helical cables that engage with gearing on the bi-directional motor. Rotation of the motor in either direction pushes or pulls the helical cables, causing the door to move toward the open or closed position. The motor can be stopped when the door reaches selected positions other than the open or closed position, holding the door in a partially open position.
    Type: Grant

  • Patent number: 6854212
    Abstract: A drive system drives a pulley along a curved track to open and close a sliding vehicle door. The pulley is pivotally mounted to the sliding door to permit the pulley to pivot when the pulley traverses the curved portion of the track. An electric motor drives the pulley through a drive belt. In operation, as the pulley pivots when it traverses the curved portion of the track, the drive belt twists. Torque transfer between the pulleys and the motor is maintained during twisting of the drive belt which thereby permits an uncomplicated yet effective system for driving the sliding door along the curved portion of track. Another drive system transmits torque through a drive shaft arrangement which rotates as the drive system traverses the curved portion of track.

  • Patent number: 6848216
    Abstract: A common drive system drives multiple systems within a sliding vehicle closure member with a single drive motor. A controller selectively connects the drive motor to either a door drive assembly, a window drive assembly, or a lock module drive assembly through a selector assembly in response to actuation of a particular input. The selector assembly includes a transmission which shifts the drive motor between multiple gear trains to drive the particular drive assembly.

  • Patent number: 6807775
    Abstract: A vehicle includes an automated drive device for powered sliding movement of the door into open or closed positions. The drive device includes a belt that cooperates with a track. A biasing member urges the belt into engagement with a corresponding portion of the track to ensure adequate engagement to achieve the desired movement of the door responsive to rotary movement of the belt. In one example, the belt and track include teeth that cooperate such that rotary movement of the belt results in linear movement of the door relative to the vehicle body.

  • Publication number: 20040172884
    Abstract: A drive system drives a pulley along a curved track to open and close a sliding vehicle door. The pulley is pivotally mounted to the sliding door to permit the pulley to pivot during traverse of the curved portion of the track. An electric motor driven pulley remotely drives the pulley through a drive belt. In operation, as the pulley pivots during traverse of the curved portion of the track, the drive belt twists. Torque transfer between pulleys is maintained during twisting of the drive belt which thereby permits an uncomplicated yet effective system for driving the sliding door along the curved portion of track. Another drive system transmits torque to pulley through a drive shaft which rotates during traverse of the curved portion of track.

  • Patent number: 6729072
    Abstract: A vehicle door lock system comprises a sliding vehicle door, having a door path of travel generally translational to a vehicle frame. A drive unit moves the vehicle door along a door path. A drive component communicates the movement from the drive unit to the vehicle door by moving along a drive component path of travel. A latch is selectively actuated to arrest movement of the drive component and the vehicle door by blocking the drive component path of travel.
