Abstract: A hinge mechanism comprising first and second connection members mounted to pivot relative to each other and having first and second circular locking bearing surfaces co-operating with respective ones of first and second locking shoes that are part of the slugs so as to hold the first and second connection members stationary, and a control device for putting the slugs in engagement with the first and second locking bearing surfaces while allowing the slugs to pivot to a certain extent about their own axes.

Abstract: This concerns a slide rail for a vehicle seat including a fixed section and a "U" shaped mobile section, a memorization runner sliding along the fixed section and defining a memorized position of the mobile section, a runner catch, a first control to simultaneously unlock the slide rail and attach the runner to the mobile section and a second control solely to unlock the slide rail. The memorization runner is brought resiliently to its locked position where it engages with notches provided on the flange of the fixed section. The runner slides on a single flange of the fixed section.
