Abstract: When a sliding door (3) as a plate-like object is moved in a front and rear direction from a closed position to an opening preparation position, a rotatable rail (20) rotates from a horizontal lying position to a vertical standing position about a rotation axis (L1). When the sliding door is in the opening preparation position, a roller (40) of the sliding door (3) rides on a running track (25b) of the rotatable rail (20). When the sliding door (3) is further moved from the opening preparation position to an open position, the roller (40) transfers from the running track (25b) to an auxiliary track (26) of an adjacent rotatable rail (20). The rotatable rail (20) is biased toward the standing position by an elastic force of a torsion spring (18) and maintained in the standing position by an arm (13). This allows the sliding door (3) to be returned to the opening preparation position.

Abstract: An arrangement for mounting a sliding door to a vehicle body for movement between an open position and a closed position. The arrangement includes a guide track mounted to the sliding door, a carriage support arrangement carried by the sliding door and a swing arm. The swing arm is connected to the carriage for pivotal movement about a first axis and to the body for pivotal movement about a second axis. With the sliding door unlatched, the swing-arm rotates the carriage support arrangement and the sliding door through an obtuse swing angle, thereby reducing longitudinal tipping forces on the sliding door. Further, when the swing-arm and sliding door are in the full-open position, the sliding door's center of gravity is only slightly offset aft of the carriage support arrangement, thereby reducing the force needed to remove the swing-arm, carriage support arrangement and vehicle sliding door to a fully-closed position.
