ABSTRACT:
An operator comprising a housing ending in a flange is provided with a turret incorporating a stepped bore for locating a worm shaft of a drive mechanism. A first seal is disposed between the worm shaft and the stepped bore. A second seal is interposed between the flange and a frame of a window. An interconnecting mechanism driven by the worm shaft comprises a pair of worm arms followed by a pair of links. The former and the latter are provided with male and female ends using, respectively, a calotte of a sphere complemented by a spherical shaped recess. Thus, between the pair of worm arms and the pair of links, pivotal joints are formed.
