Abstract

Synchronizing mechanism comprises a spring arrangement (10) having an extension spring (24) arranged parallel to the sliding direction of a seat support (4) and between a bearings. Preferred Features: One or more bearings for increasing the spring length can be adjusted to adjust the pre-tension of further extension springs (22). Each adjustable bearing is formed by a receiving hook which is hinged on an cam. The cam can be rotated by an adjusting drive via a worm gear pair.
