This invention relates to a friction drive mechanism 10 for a motorized sliding door 11. The door 11 is suspended by a first rail 12 and its movement guided by a third rail 13. A second rail 14 is flexibly coupled to the first rail 12 and biased against a motorized driving roller 16 by a simple tensioning mechanism 17. The tensioning mechanism 17 maintains the friction contact between the driving roller 16 and the second rail 14. The flexible coupling 15 joining the first and second rails 12,14 compensates for any misalignment in the mounting of the componentry. The flexible mounting 15 also allows for the door 11 to be driven around curves. |
