Abstract
The van (10) has a sliding door (14) mounted on rollers (22, 24 and 30) that are supported by and slidable in tracks (16, 18 and 20). An opening and closing module (50) is mounted inside the van adjacent to the center track (18). A front cable (74) is attached to the front cable drive pulley (144), and extends from the pulley through a front cable roller guide assembly (54) and is attached to the hinge and roller assembly (26). A rear cable (100) is attached to the rear cable drive pulley (136) and extends from the pulley through a rear cable roller guide assembly (56) and is attached to the hinge and roller assembly (26). The front and rear cable drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove 210. A motor (126) rotates the front and rear cable drive pulleys to move the sliding door. The small diameter cable grooves (208) drive the sliding door (14) when the door is in the forward portion of the tracks. The large diameter spiral cable grooves (164) drive the sliding door when the door is in the center and rear portions of the tracks. Fixed idler rollers (226 and 254) guide the front and rear cables (74 and 100) to and from the cable drive pulleys (136 and 144).
