摘要

The arrangement includes a gear-box (11) with a freely rotating screw wheel (12) of a worm gear, and with a rope drum (15) turned by the screw wheel, on whose extent a rope for driving a cover element is rolled up. The rope drum is combined with the snail wheel in direction of an axis to a single unit (19), and is enclosed at its extent by a drum reception (17) with a radial spacer (18). The drum reception forms a single piece with the gear-box, whereby gear-box with drum reception, and snail wheel with rope drum are respectively manufactured as light-weight plastic die-casting parts.
