Abstract
This invention relates to a vehicle seat track assembly. The assembly comprises a first track member having an upwardly facing bearing surface and a second track member for attachment to a vehicle seat, the second track member having a downwardly facing bearing surface. A cage is disposed between the first track member and the second track member. The cage carries a rolling element that is in rolling engagement with the upper and lower bearing surfaces to provide longitudinal movement of the first track member relative to the second track member. The cage is provided with at least one pad section for engaging at least one of the upwardly and downwardly facing bearing surfaces. In an unloaded state, the at least one pad section separates the upwardly and downwardly facing bearing surfaces from each other by a distance which is greater than the diameter of the rolling element.
