Abstract
A device for compensating for clearances between a satellite and toothings of flanges of a reducing mechanism provided for adjusting the position of a seat. The mechanism has a fixed flange and a mobile flange that are held against one another via a crimped ring and enclose an eccentrically mounted satellite that bears on a cam driven by a shaft. This shaft has a square section with a first conical portion, and with a cone that is disposed in a central opening of the fixed flange. A spring is disposed between the cone and a peg provided on the shaft. When a hard point is met upon cooperation of toothings of the fixed and mobile flanges with a double toothing of the satellite, a slight longitudinal offset movement of the shaft in either direction is produced, resulting via one of the first conical portion and the cone in a change in eccentration of the satellite, thereby providing for passage of the hard point. As soon as the hard point is passed, the spring, which was stressed during the movement of the shaft, returns the various components to a starting position, thereby reestablishing an original eccentricity.
