Abstract
The reversible endless screw slides are fixed by their lower fixed elements to the vehicle floor via a base plate. The base plate is mounted under at least one of the two slides and carries a profile section forming a rack cooperating with a reversible endless screw and which can be locked by a second shoe. The movement of the second shoe is controlled by a lever able to pivot against action of springs via another lever fast with an articulated control bow placed between the two slides so as to free the endless screw placed in a casing and cooperating with the rack for forming a mechanical memory for the slides.
