Guide especially for vehicle seats, with runner rail with top and bottom track

摘要

The two tracks (1e,1a,1b) of the runner rail (1) are joined by a profiled arm (1f). A roller (4) rotarily mounted on a support bolt (2a) rolls along the lower track (1a,1b). A tension roller rolls along the top track (1e) and is in the form of a ring (6) enclosing the runner roller, protruding beyond its periphery and mounted coaxially with the runner roller. The elastic ring maintains a distance apart from the opposite facing part of the lower track, and freely rotates in relation to the runner roller. The ring has an inner bearing ring (5) mounted so as to rotate freely on the runner roller. The ring is positioned inside a groove (4c) guiding it laterally and positioned round the periphery of the support roller.
