Patent 7059654 was granted and assigned to Mitsui on June, 2006 by the United States Patent and Trademark Office.
A door system includes a front door and a rear door that are configured to shut together a continuous opening in a vehicle body; a striker configured to be inserted in both the front door and the rear door so as to couple the front door and the rear door when the continuous opening is shut by the front door and the rear door. When at least one of the front door and the rear door is opened, the striker is drawn out from one of the front door and the rear door so as to cancel the coupling between the front door and the rear door.
