1. An articulating closure system comprising:
- a body having an opening;
an articulating door having a middle area and closing at least part of the opening;
a dual pivot mechanism pivotably attached to the body about a first pivot axis and pivotably attached to the articulating door near the middle area about a second pivot axis, the dual pivot mechanism supporting the weight of the articulating door on the body; and
an arm assembly pivotably attached to the articulating door and pivotably attached to the body, and guiding movement of the articulating door so that the articulating door always faces in a substantially constant orientation, wherein the arm assembly includes a first link having a first pivot length and a second link having a second pivot length and wherein the distance between the first pivot axis and the second pivot axis defines a third pivot length and wherein the first, second and third pivot lengths are all equal.

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.

14. An articulating closure system comprising:
-
a vehicle including a body having an opening, the opening being substantially uninterrupted and the body including a rear wheel house;
an articulating door having a rear edge and a forward edge and closing a rearward part of the opening, the rear edge being positioned substantially over the center of the rear wheel house when the articulating door is in a closed position;
a dual pivot mechanism pivotably attached to the body about a first pivot axis and pivotably attached to the articulating door about a second pivot axis, the dual pivot mechanism supporting the weight of the articulating door on the body;
an upper control arm assembly pivotably attached to the articulating door and pivotably attached to the body, the upper control arm assembly guiding movement of the articulating door so that the articulating door always faces in a substantially constant orientation as it moves through an arc between the closed position and a full open position, the forward edge of the articulating door being positioned substantially over the center of the rear wheel house when the articulating door is in the full open position; and
a swinging door having a forward edge and being pivotably attached to the body near the forward edge, the swinging door closing a forward part of the opening, wherein the upper control arm assembly includes a first link having a first pivot length and a second link having a second pivot length and wherein the distance between the first pivot axis and the second pivot axis defines a third pivot length and wherein the first, second and third pivot lengths are all equal. - View Dependent Claims (15, 16, 17, 18)
