Abstract
The slide comprises two fixed lower sections and two upper sections. A gear-down mechanism is rigidly connected to one of the upper sections, the fixed lower section having an inner face provided with a toothing forming a rack. Reversible endless screws are mounted on a shaft able to rotate freely with respect to the rack and are blocked in the position chosen for the seat by shoes with inclined upper sections normally pressed against each other by springs an unlocked by flat portions of a bar having a controlled rotation. The seat is manually displaced.
