Vehicle seat track assembly

Abstract

A vehicle seat track assembly wherein guide elements are mounted on one of a pair of cooperating track structures. The guide elements have generally vertically facing guide surfaces which have been broached to be positioned a predetermined distance vertically from generally opposed spaced surfaces on the one track structure. The vertically facing guide surfaces slidably engage generally oppositely facing surfaces of another of the track structures so as to effectively prevent relative vertical movement in a direction tending to vertically separate the track structures. When used in a manually actuated mode, the track assembly includes a locking assembly comprising a pair of abutting metal plates stamped to provide abutting elongated mounting portions having a plurality of spaced abutting locking portions extending transversely therefrom, a mounting structure within which the mounting portions of the abutting plates extend and a spring constructed and arranged to resiliently bias the mounting structure and abutting plates into a locking position wherein the locking portions are within selected notches and to enable the mounting structure and abutting plates to be manually moved against the resilient bias into a releasing position wherein the locking portions are out of the notches.
