Abstract
An adjustable, automotive vehicle seat track having slidably interfit upper and lower tracks. The upper track is generally cross-shaped and includes a vertical web and a horizontal web. Opposite longitudinal edges of the horizontal web define a pair of inwardly opening, longitudinal channels. A pair of opposed, longitudinal flanges extend outwardly from the bottom edge of the vertical web. The lower track is generally U-shaped in cross section and includes a pair of longitudinal flanges slidably interfitted with the horizontal web channels and a longitudinal channel slidably interfitted with the vertical web flanges. The lower track channel is partially closed around the vertical web flanges to resist separation of the upper track from the lower track.
