ABSTRACT:
A chair assembly (20) for chairlift including a seat (22) and enclosure member (43) mounted to the seat (22) for movement between open and closed positions. The chair assembly (20) has a drive (51) for moving the enclosure (43) which includes a rail (52) mounted to the movable enclosure member (43) and drive rollers (56, 57) carried by the frame (26) of the seat assembly (21). The drive rollers (56, 57) are powered by motion of the chair assembly (20) through actuator rollers (82, 83) that engage stationary actuator rails (84, 85) at the chair terminals. The actuator rollers (82, 83) are coupled by flexible drive cables (87, 88) to the drive rollers (56, 57) so that movement of the chair along the actuator rails (84, 85) produces rotation of the actuator rollers (82, 83) and the drive rollers (56, 57), which displaces the rail (52) and movable enclosure member (43).
