  • Patent number: 8428828
    Abstract: An apparatus is provided for controlling an automated closure panel in a vehicle. The apparatus includes a command module configured to generate a control signal. A motor is configured to actuate the automated closure panel based upon the control signal. A motor sensor is configured to measure an output characteristic of the motor, with the motor sensor having a motor sensor output signal. An adaptive logic module is coupled to the command module and to the motor sensor. The adaptive logic module is configured to provide an output to the command module to thereby adjust the control signal, wherein the adaptive logic module is configured to determine when the automated closure panel is obstructed by an obstacle based upon the motor sensor output signal.

  • Patent number: 6641201
    Abstract: A vehicle body has a roof-enclosed passenger compartment and a rear cargo compartment. The cargo compartment has a cover and a tailgate to close the cargo compartment. The cover is movable along a pair of tracks from its closed position on the cargo compartment to a stowed position on top of the passenger compartment. The cover has an intermediate position above the cargo compartment which serves as a camper top and with the addition of zip-on side covers converts the vehicle body to a camper. The intermediate position of the cover in conjunction with the roof of the vehicle body also provides support for hauling long cargo.

  • Patent number: 6447054
    Abstract: A vehicle access system includes an access opening for the passenger compartment that is closed by a swinging door in combination with an articulating door. The articulating door moves through an arc without angling away from the vehicle body and is supported on a hinge assembly that attaches near the center of the door. An arm assembly guides the door throughout its range of positions and maintain the door in an orientation that is substantially parallel to the vehicle body. When the doors are open, an uninterrupted access opening is provided to the area of the second and third seat rows of the vehicle.

  • Patent number: 6317925
    Abstract: A hinge trim system including a covering portion overlying at least a portion of at least one of the exposed surfaces of a hinge, wherein the covering portion can include one or more covering surfaces overlying the hinge so as to maintain a barrier surface between one or more pivot points and the covering portion. Additionally, selected portions of the covering portion move as the hinge moves so as to maintain a barrier surface over a substantial portion of the hinge as the hinge moves from one position to another.
