Abstract
A vehicle seat suspension has lower and upper housings with the upper housing adapted to support the seat and having longitudinally extending side tracks. A linkage assembly having a plurality of links connects the lower and upper housing. A plurality of side rollers are mounted to the links and ride in the side tracks, each rotating on a horizontally extending axis. Each of the side rollers has an outer conical bearing surface and each of the side tracks has an angled outside wall. The outer conical bearing surface of each side roller and the angled outside wall of each side track have an angle relative to vertical to facilitate their rolling engagement. The side rollers engage the longitudinal tracks at spaced locations to stabilize the upper housing in a direction generally perpendicular to its fore and aft travel path.
