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.

Abstract: A vehicle seat adjustment system has at least two tracks and each track includes: a stationary female number, a male member slidably mounted in the female member, and a unitary locking device for removably securing the male member in the female member. The device has a first end secured to the female member, an intermediate flexible section, and a vertically displaceable second end section. The second end section has an L-shaped flange received within a slot formed in an upper surface of the female member. Cutouts are longitudinally formed along a bend in the flange and normally engage: a) longitudinally formed notches in an upper surface portion of the male member; and b) longitudinally formed notches in a flange return of the female member, the return underlying an outwardly extending flange of the male member. Vertical displacement of the locking device removes the cutouts from the engaged notches thereby allowing sliding movement of the male member within the female member.
